DR. GORDON: Good morning. Nice to have you. Our other commissioners are coming in momentarily. Thank you for being so prompt.
Before we begin each morning, we just sit quietly for a moment and gather ourselves in the space.
[Momentof silence observed.] Panel
DR. GORDON: Thank you. This is
the second day of the panels on research. This first panel is on research
methodology. We will begin with John Chabot.
Presenter:
DR. CHABOT: Good morning. I am a
surgeon, which may be unique in this group. That gives me a bit of
perspective that other people don't have. I came to alternative medicine,
to an interest in alternative medicine, through research, rather than the other
way around. I suspect most people you will be hearing from developed an
interest in alternative medicine first, and then developed a research focus
there.
What happened to me was, several years ago,
the director of our Comprehensive Cancer Center, Karen Antman, was approached by
the NCI to look at designing a trial to study the protocol used by Nick Gonzalez
to treat various cancer patients, and specifically we were asked to think about
pancreatic cancer.
Karen approached me, as our local pancreatic
cancer person, and said, would you consider it.
At that point, I had no personal experience
with alternative medicine treatments or any specific interest. I looked
through Nick Gonzalez's data and became much more interested.
Initially, I looked at it from a very
skeptical perspective. His results were so remarkable, in fact, that I was
completely suspicious. As I went through his data and his information,
became more and more convinced that the pilot trial that he had done under the
auspices of the NCI was both valid and important.
He, over several years, treated 11
pancreatic cancer patients with a regime that he had developed from historical
data. The regimen primarily consists of very high-dose pancreatic enzyme
supplements in conjunction with a very rigorous nutritional program that is
highly, highly specific, day to day, highly specific dietary regime that leaves
very little room for deviation. It includes fresh juices, prepared on the
day. It includes micronutrient supplements. It includes cleansing
and cathartic regimes at specified time intervals.
The data on those first 11 patients
demonstrated a 17-month median survival for patients with advanced pancreatic
cancer. In looking through the data records, it became clear to me that
these, in fact, were all patients with documented pancreatic adenocarcinoma, and
it was advanced disease. So the initial skeptical thought being, well,
these aren't real cases, I certainly convinced myself that these were patients
who had real cases of pancreatic adenocarcinoma.
The longest surviving patient in that group,
I actually interviewed. Because he had a very limited disease remaining,
he asked me if I would consider re-operating on him. He was four and a
half years out from his original disease, was deemed unresectable initially, had
been on the regimen for four and a half years and had what appeared to be very
limited disease by all measurements.
I was interviewing him to get data, but he
eventually convinced me to do an operation on him, and I found him, at that
point, to still have unresectable, poorly differentiated pancreatic
adenocarcinoma.
With that in mind, the treatment became a
very real potential therapy for advanced pancreatic cancer, in my mind, and we
set about designing a trial. We put together a standard, randomized trial
to compare Gemcitabine, which is the standard chemotherapeutic agent for
advanced pancreatic cancer with the Gonzalez regimen. It was funded by the
NCI, and we worked to get it through our various internal regulatory bodies, the
Institutional Review Board and the Cancer Committee.
That represents an important hurdle, I
think, in trying to do these trials, because just as there are strong advocates
of alternative medicine, there are strong biases against alternative medicine
and working through those committees is a chore when you are trying to do this
sort of trial. We were successful. We designed a good trial.
Scientifically, it was valid, and we made it through the regulatory committees.
The initial year of the trial, we had a huge
interest. There was a fair bit of publicity about this, none of it
solicited by us, but with a lot of press involvement in these sort of
trials. We were on TV and in the newspapers. We had huge numbers of
patients call with interest. Many, many, many of the patients did not fit
the eligibility criteria we had set, which are really very narrow. Those
patients who did fit the eligibility criteria, there were almost none of them
who were willing to enroll in a randomized trial.
In the first year, we randomized three
patients into the trial, despite a huge interest, enough patients to easily fit
into the pattern where we would expect to be able to complete the trial.
It became very clear that we would never collect adequate numbers of patients to
come to a conclusion.
So that, we then got the research group back
together, tried to make a decision, and did come to a conclusion that we could
do this trial in a non-randomized fashion by carefully stratifying the critical
variables. We went to the literature and confirmed that the two critical
variables in determining anticipated survival in patients with pancreatic cancer
were extent of disease, basically volume of disease, and the patient's ability
to eat.
With those two critical variables, we
redesigned the trial, resubmitted it for approvals, and we are now running a
trial where patients can choose which therapy they receive, whether it is a
chemotherapy-based treatment or the Gonzalez regimen, and we are stratifying
those two important variables to generate a control group as well as the
experimental group.
We now are accruing patients
regularly. From a practicality perspective, this trial, I think, will
effectively collect the appropriate number of patients for us to draw a
conclusion. In the absence of a randomized design, there are obvious
pitfalls here in drawing conclusions from the data once it is generated, the
randomized design being much easier to eliminate biases.
So that is where we stand today in my
experience over the last two and a half years with this particular trial.
Now knowing a bit about alternative medicine, I have come up with several
observations, and I think they can only be called observations at this
point. Among those people that we have screened for this protocol, the
bias toward alternative therapy is very, very strong.
The vast majority of people who call with
interest are only interested in alternative medicine approaches. Patients
who express interest in this protocol are generally healthier than the overall
population of patients that I see in my practice with advanced pancreatic
cancer. The way this protocol, and, I suspect, many are designed, the
patients who meet the eligibility criteria are clearly healthier than the
general population of advanced pancreatic cancer patients.
One has to be very careful coming to any
conclusions comparing these patients with the general population of pancreatic
cancer patients.
I will stop at my third observation.
The effects of psychosocial support and delivering hope to these patients is not
insignificant. In the absence of a blinded, randomized trial, separating
these effects from the physiologic and pharmacologic effects will be a major
challenge in trial design.
DR. GORDON: Thank you very much, Dr.
Chabot.
Marcia Angell.
Presenter: Marcia Angell, M.D.
DR. ANGELL: Thank you for inviting me
to address you this morning.
CAM is an umbrella term for a large number
of disparate practices based, often, on very different theories. They
include homeopathy, therapeutic touch, naturopathy, chiropractic, acupuncture,
and on and on. Many of them have very little in common, except for the
fact that they are practiced, largely, in the absence of good scientific
evidence to support their use. More about that later.
Because CAM consists of such disparate
practices, it makes no sense to imagine that a single research methodology would
apply to all of them. A clinical trial of acupuncture, for example,
presents different methodologic problems from a trial of an herbal remedy.
The former would require particular
attention to the selection of a comparison group, or more likely comparison
groups, whereas the latter, a trial of an herbal remedy, would require
particular attention to the composition of the product being tested.
Still less, does it make sense to imagine
that we need a brand new methodology to study CAM. The problems in
designing trials of new drug combinations to treat leukemia, for example, are
not all that different from the problems in studying herbal remedies. The
problems in studying fetal cell transplantation for Parkinson's disease are
similar to those of studying acupuncture.
Almost none of these methodologic problems
are insoluble. For years, scientists have managed to devise valid,
sometimes quite ingenious, ways to study potential new remedies, and there is
nothing qualitatively different about CAM.
Despite some differences in the details of
research methodology, the overarching approach must be the same, the application
of the scientific method. This means formulating a hypothesis that can be
tested. It is no good to have a hypothesis that can't be tested, designing
a study that will actually test it, collecting verifiable data, and drawing
those conclusions, and only those conclusions, that follow from the data.
The hallmark of the scientific method is its
utter reliance on evidence. No evidence, no conclusions. In the case
of proposed medical treatments, CAM or otherwise, randomized, controlled
clinical trials are usually required, not always but usually. That is
because they eliminate or reduce biases that stem from confounding variables,
variations and uncertainties in natural history, the placebo effect, and the
expectations of researchers and subjects.
Needless to say, the condition that is being
studied must be precisely defined, and the outcomes precisely defined, so that a
study can be replicated.
I want to emphasize that the scientific
method is not one of a number of options. It is the only way to answer
questions about the natural world, and the human body is a part of nature.
It is not a cultural or Western phenomenon, it is universal.
True, it has emerged and been applied at
different rates in different parts of the world, but that is mostly a reflection
of economic conditions. Whenever countries can afford to adopt what is
sometimes called Western medicine, they do. Medical care in Japan, for
example, is not much different from medical care in the United States.
Even in China, Western medicine is replacing traditional practices.
Now, I would like to say a few words about
the questions you posed to this panel. Many of them, I think, are in the
form of, have you stopped beating your wife, in the sense that they are based on
a dubious premise. The premise is that there is something different about
studying CAM that will require modification of current methodologies.
Let me highlight two of the
implied differences because they are, in fact, not different at all. You
seem to suggest CAM is unique in involving multiple interventions and complex
systems. That is simply not true. The standard treatment of diabetes
or childhood leukemia, for example, involves multiple interventions and complex
systems.
Many standard drugs, such as digitalis, were
derived from complex botanicals. It is important, nonetheless, that the
various components of treatment regimens be sorted out so that the contributions
of each are identified.
You also imply that CAM is different because
it requires individualization of treatment, but in standard medicine, good
doctors have always been ready to select or modify treatment according to
individual response. What is not possible, in general -- there are
exceptions -- but what is not possible in general, is to evaluate the safety and
effectiveness of new treatments in individuals. That requires a sample of
a population, and the population can be chosen to be as diverse or as
homogeneous as possible. It depends on what you want to find out.
Fortunately, humans are more similar than
they are different. So that, a beta blocker or a healthy diet tend to work
in everyone in much the same way, although not in the identical way. The
fact is that there are not two kinds of medicine, CAM and standard
medicine. There is only medicine that has been adequately tested, and
medicine that hasn't; medicine that works, and medicine that may or may not
work.
In general, CAM falls into the second
category. Standard medicine falls into both. I don't want to imply
for a second that all standard practices have been scientifically tested.
This would be a good time to say a few words
about the German Commission E monographs, since they are often considered a
source of scientific evidence on herbal remedies. Commission E was
established by the German Government in 1978 to evaluate the safety and
effectiveness of herbal remedies. Over the years, it issued its findings
in a series of 380 monographs, now collected together and translated.
Here is the shocker. They contain not
a single citation to any research study. The introduction to the English
translation of the compendium states that, "Only in conflicts or cases of
disputes to the medical act can an attorney or scientific organization view
these references."
Even then, the references might not be
there, since, "Some of the materials upon which the monographs were based were
unpublished studies of proprietary products from manufacturers in
Germany." In fact, it is acknowledged that many of the monographs are
based only on materials supplied by the KP, an organization of German
manufacturers.
Now, no one should accept ex-cathedra
pronouncements about scientific research, no matter what the source, without
having access to the evidence on which they are based. In this case, it
seems the opinions are not just those of an unbiased governmental body, but also
of the industry that gains from favorable evaluations.
One should also be wary of accepting the
notion that there is a gold mine of scientific information sequestered in
another language. Since science is universal, and English is a lingua
franca of science, that is highly unlikely.
In summary, we need to get on with the job
of testing CAM treatments rigorously, because millions of people are taking
remedies for which there is little or no evidence. Tradition,
testimonials, and speculation are no substitute. This has been
demonstrated repeatedly throughout medical history. What seemed true, and
sometimes had seemed true for millennia, often proved false.
The spectacular advances in clinical
medicine during the 20th century correlated with the growing acceptance of the
need to demonstrate scientifically. Whether biologically implausible
remedies should be tested is arguable, since we don't have the resources to test
everything.
I have come to believe, somewhat
reluctantly, that even biologically implausible remedies should be tested for
safety and effectiveness if, and only if, they are already being widely
used. If they are shown, and any other remedy is shown, to be effective
and reasonably safe, they should be incorporated into clinical practice,
regardless of whether they originate as CAM, but there are no shortcuts and
there should be no free passes.
Thank you.
DR. GORDON: Thank you very much.

Homeopathy has long been an enigma, due
largely to the high dilutions of the medicines that are used. While the
mechanism of action of homeopathy is not known, nearly 200 years of anecdotal
evidence from all parts of the world has convinced many patients as well as
physicians of its efficacy.
In France, 33 percent of medical doctors use
homeopathy in their practices, while in India, it is used by up to half of the
population. In that United States, 3.4 percent of the population used
homeopathy in 1997, which was a five-fold increase since 1990.
Homeopathy is based on the "principle of
similars," first described by Samuel Hahnemann in the late 18th century.
Substances that have been found to cause certain symptoms in someone who is
healthy are used to treat those same symptoms in someone who is sick.
Another important tenet of homeopathy is
individualization, whereby each person is treated with a specific remedy which
fits his or her unique pattern of physical, emotional, and mental
symptoms. For this reason, different people with the same diagnosis may
receive one of several different homeopathic medicines.
Homeopathy has been found to be extremely
safe, due to the low concentrations of active substances, as well as efficacious
in many clinical trials. A meta-analysis published in "The Lancet" in
1997, established clearly the efficacy of homeopathy when compared to
placebo. The investigators also found, however, that many studies had not
been replicated, something that has changed since the time of that meta analysis
publication.
Homeopathy has also been found to be cost
effective, reducing by more than half the use of conventional medicines in those
physicians who use it. In France, where homeopathy is included in the
national health system, medical costs have been estimated to be 15 to 25 percent
lower for homeopathic physicians. The average cost of a bottle of 100
homeopathic tablets in the United States is $5 to $10.
There are many barriers, both political and
methodological, to carrying out good homeopathic research. Many of these
things also apply to other areas of CAM research. The first is
funding. Funding has been limited by the fact that homeopathic medicines
are generic and cannot be patented. Thus, there are no profits to be made
from investments in research. Because of this, sample sizes have been
relatively small in homeopathic trials, which means that only large differences
can be detected between treatment groups.
In the childhood diarrhea research that I
carried out, p values in the range of 0.03 to 0.05 were found in individual
studies of 87 to 125 patients. However, when these studies were combined
to yield more than 200 patients, the p value drops to 0.002. If enough
money is available for enough subjects, even small differences in effects can be
found to be statistically significant, as is the case for many highly marketed
allopathic drugs.
Unlike other CAM modalities, homeopathy
lends itself well to conventional, randomized, placebo-controlled trials, the
RCT, which is the gold standard, as we have heard. This is because
homeopathy is prescribed on sugar pills. However, the individualized
nature of homeopathic practice makes a strict application of RCT methodology
difficult. Unlike trials in conventional medicine, all patients with the
same illnesses are not prescribed the same medicine in homeopathy.
Several strategies have been used to
incorporate individualization into the RCT study design. These include
individualizing the treatment each subject receives, and comparing the outcome
of the homeopathic group, as a whole, to placebo; limiting study subjects only
to those who fit a specific remedy picture; and using combination remedies that
contain the most common medicines for a specific illness.
Another area of importance is outcome
measures. It is important that outcome measures reflect the holistic
nature of CAM practices. In conventional medical research, often one or
two specific parameters are looked at, such as a blood pressure measurement or a
blood test. You do not really see the effect of the intervention on the
patient as a whole.
This can be solved by using already existing
symptom scores, such as the Kupperman Menopausal Index for hot flashes.
More globally, quality-of-life indicators, such as the SF-36 Health Survey, can
be used to evaluate subjective feelings as well as limitations of work, social
activities, and general health status. Other outcomes, such as days of
missed school or work, the cost of medical care, and patient satisfaction, are
all important in evaluating CAM modalities.
The use of placebo is an area of controversy
in CAM research, but it is necessary to establish efficacy, especially for
therapies such as homeopathy, which are thought be some to be nothing but
placebo. However, there are ways to use placebo to minimize the ethical
difficulties. One is to limit the time of the study to the shortest
possible to measure a clinical effect and to offer all patients the opportunity
to receive active treatment at the end of the study.
Once the efficacy of homeopathy is
established firmly, the use of placebo can be eliminated by randomizing subjects
to receive either conventional medical care or homeopathy. This would give
a more accurate representation of what homeopathy has to offer in actual
clinical practice. Longitudinal studies of homeopathic patients over
several years, should document the preventative as well as curative aspects of
this modality, as well as cost analysis.
There is now adequate evidence-based
research to justify the use of homeopathy in several conditions, yet the belief
structures of scientists continue to block its widespread application.
Many critics have stated that no matter how many clinical trials are published,
they will never accept homeopathy until its mechanism of action is
understood. This, in my view, is foolhardy, as there are many drugs in
modern medicine which were used for many years before their mechanism was
understood.
It is also chauvinistic for us to think that
we understand everything there is to know about science at this point in
history. Homeopathy does work, most likely on a subatomic or a subtle
energy level that has not yet been elucidated.
My first recommendation to the Commission is
that the government establish an initiative to find out how homeopathy
works. This could revolutionize our understanding of health and disease,
as well as open the door to other new healing strategies.
Modern medicine is at an impasse; $425
billion per year are spent treating the six leading illnesses, and costs
continue to rise. Drug costs now exceed $100 billion per year, and are
predicted to reach nearly $400 billion by 2010.
Recent studies have shown that adverse
reactions to allopathic drugs, used as directed, is the fourth leading cause of
death in hospitals. One survey showed that more than half of all
physicians said they would not do it again, when asked about their decision to
go into medicine.
In the 1999 special issues on alternative
medicine, the editors of JAMA wrote: "There is no alternative medicine.
There is only scientifically proven, evidence-based medicine, supported by solid
data, or unproven medicine for which evidence is lacking."
Homeopathy deserves the kind of careful,
unbiased evaluation that is necessary to establish its legitimacy. The
Commission should charge the government agencies to thoroughly investigate
homeopathy, so that it can become available within the health care system to
anyone who wants it.
Well-funded research into clinical efficacy
and cost effectiveness should demonstrate that homeopathy is a low-cost way to
provide health care to a wide segment of our population. It may also make
them healthier. Thank you.
DR. GORDON: Thank you very much.
Alex White.
Presenter:B. Alex White, D.D.S., Dr.P.H.
DR. WHITE: Good morning. My name
is Alex White, and I appreciate the invitation to come and talk with you today.
I serve as the principal investigator of the
Oregon Center for Complementary and Alternative Medicine, which is based in
Portland, Oregon, part of Kaiser Permanente. It is a collaboration of four
complementary and alternative medicine schools in Portland, as well as the
Oregon Health Sciences University.
What I would like to talk to you about this
morning are some of the experiences and learnings from about two years
together. Many of the recommendations that I will talk with you about this
morning are in your packet, and some of the background materials as well.
I should give a bit of a disclaimer. I
work for Kaiser, but I am not representing Kaiser. I am representing the
Oregon Center, so my comments should be taken in that context.
We are fortunate, actually, in Portland to
be able to have this institutional collaboration with the College of
Chiropractic Care, Oriental Medicine, Massage, and Naturopathy, as well as the
Oregon Health Sciences University School of Medicine and Dentistry.
Together with those institutions and Kaiser at the Center for Health Research,
we put together a center grant that is supported by the National Center for
Complementary and Alternative Medicine.
I would like to talk, generally, about three
areas: first, is research; the second is research methods; and the third is
infrastructure. I think some of the themes I would like to talk about with
you are some themes that you have heard from the other speakers. So that
is a good thing.
I think the fundamental and most important
thing that we need to focus on is doing good science. Without good
science, places like Kaiser and other payers, other practitioners, are not going
to incorporate CAM therapies into routine clinical care. That shouldn't in
and of itself be the goal of science, but it should certainly be to improve the
health and health care of our members, and research is an important tool to do
that. But it has got to be based on good science.
We go through processes that use science and
make recommendations for additions to the formulary for deciding what new
technologies to cover. Those decisions are based, among other things, on
good science. Certainly, politics and other things come into play in that
process, but science is the critical feature of each of those processes.
So we need to conduct good science on those products and processes, looking at
particular diseases, particular conditions that need to be addressed.
We also need to expand, I think, the
research to include factors that may influence that process. We need to
understand what it is about practitioners and patient characteristics that
influence good outcomes, to understand what it is about theories and beliefs and
ideas about how things work that may or may not influence the process and
outcomes of care.
We also need good research on
outcomes. I think, as was highlighted by the other speakers, we need
measures of outcomes that are going to reflect what is important to the patients
who receive that care, as well as to the practitioners who are providing that
care. They are broader than what are most used as clinical measures of
outcomes. I think clinical measures are an important part of assessing CAM
therapies, but we also need to look at things like economics. We need to
look at psychosocial impact of CAM therapies on health beliefs and, simply,
quality of life.
We need research that is going to help us
integrate CAM therapies into health plans or into routine and conventional
medical care. For example, we need research that is going to demonstrate
product safety. Not only is it important to demonstrate safety, but we
need to develop some standardization within natural products. We need to
look at good manufacturing processes.
We have got efforts afoot at Kaiser to try
to identify products that we can include in our formulary, and one of the
problems that we run into continually is, can we get good standardized products
of high quality, and it is very difficult to do that. So I think research
and efforts that can begin to introduce that information, and the evidence is an
important part for enhancing CAM therapies.
We also need to think about research more
broadly than simply clinical research, and think about, certainly, mechanistic
and biobehavioral research, but as well to think about health services research,
to think about cost and cost effectiveness, and to begin to look at how CAM
therapies can be integrated within conventional care settings.
The second area I would like to talk about
is research development. While I agree with the other speakers, that many
of the methods that we need to evaluate CAM therapies are in place now, there
are, I think, unique parts about CAM that we need to evaluate, whether the
current methods will be able to capture the important features of CAM therapy.
For example, we have developed as part of
our CAM Center, this huge packet of questionnaires. We refer to it as
"death by questionnaire." The members who are willing to participate
literally spend hours filling out questionnaires.
It is not that we are trying to kill them,
but what we are trying to do is to see if there are aspects of individual
members who are participating in our studies that make them more or less
receptive to CAM therapies; not only does the CAM therapy work, but is there
something about the mindset that people bring to clinical trials.
Certainly, I think that is true in conventional medicine, and perhaps even more
important in CAM therapy.
If we are asking a person to be randomized
to a trial where there is acupuncture, there is chiropractic care, there is
massage, and there is conventional care, can we really believe that they are
willing to be randomized to each of those arms, and if not, do they have
inherent preferences about which one they would like to be in; are there ways
that we can design clinical trials in the randomization process to account for
preferences in practitioner and patient beliefs about certain therapies.
I think one of the important parts that we
need to work on in research development is understanding the mechanisms of
action of CAM therapies to get the bio markers and other ways of assessing what
it is that we are doing to members, and how is it that they have come to benefit
from these therapies.
Finally, the infrastructure. As I
mentioned earlier, in Portland, we are very fortunate to have these
collaborations established, but I will tell you that it has taken a lot of time
and effort. There are people who are participating with us that are
following on the next panel, and perhaps that will come up. I will tell
you that it is a major investment of time and effort.
There is lots of enthusiasm within the CAM
community in Portland to participate in our clinical trials. The problem
is that many of the folks don't have the necessary research training and
experience to do that. Many of the institutions are geared toward
providing education and training clinicians, and not conducting research.
So there is infrastructure, not only in
providing training and education for new CAM practitioners, but also providing
infrastructure and training to institutions to allow them to participate in NIH
trials. When we began this process, many of institutions had no idea what
indirect costs were and how you come up with a negotiated rate with HHS.
For us, it is the lifeblood of what we do, and that is just part of our
operating business. So I think there are some very fundamental things that
need to be established within the CAM community to support CAM research.
Secondly, as I mentioned earlier, the
training of new researchers in the area, that is going to come up in the next
panel, but I think it is really important to talk about it in the context of
research as well. NCCAM and other places at NIH support training grants
for new investigators. I also think it is important to think about the
role that CAM centers can play in supporting and building a cadre of
investigators who can either be collaborators or turn into principal
investigators.
At our center, we have made a significant
effort to try to include people who do not have doctoral degrees, massage
therapists, acupuncturists, and others, who have come to appreciate research
methods, who will never be principal investigators on NIH-funded grants, but who
will understand the scientific process, who will learn to ask important
questions, who will begin to evaluate their clinical practice in clinical ways,
and can collaborate with us in developing new protocols that answer questions
that are important to them.
Through that process of developing a cadre
of perhaps non-principal investigators, but certainly investigators, we believe
we can advance CAM science in important ways because we can work with the
community in answering questions and addressing issues that are important to
that community.
The final point about infrastructure I would
like to make is that many of the CAM centers, I think, have had success in
developing these Phase 2 trials, or trials that establish whether or not a CAM
therapy is efficacious, but as we begin to think about moving trials into larger
trials, I think the journalizability issue is important. The CAM therapies
are going to need to be evaluated in multi-site clinical trials, looking at the
impact of culture, looking at the impact of geography and preferences, in
whether or not these interventions work.
That requires a substantial amount of
investment, and infrastructure beyond what we have in place in Portland and
other CAM centers, but infrastructure on a national level that allows us to do
many of the trials that are supported, for example, by NCI or NHLBI, that we are
able to provide an infrastructure to do a national study looking at chronic pain
and to have support to do that.
Let me just close by reiterating again that
I think the research in CAM and the evidence base for CAM is less well developed
than it is in other areas, and that research is an important way, the only way,
I think, that we can advance CAM therapy. The objective, then, is to
assure the best possible science, and as Marcia Angell said, adhering to the
good scientific method and developing hypotheses that can be tested.
I do think that there are some areas we need
to explore and understand, whether these research methods can be applied
directly to CAM, or whether we need to tweak the methods to understand how it is
and what it is about CAM that we are trying to evaluate, and making sure that we
are not missing some important parts of CAM therapy in improving the health of
people who use CAM. Thank you.
DR. GORDON: Thank you very much.
Bruce Rabin.
Presenter: Bruce Rabin, M.D., Ph.D.
DR. RABIN: I want to thank you for the
opportunity to address some issues regarding research methodology in
complementary and alternative medicine.
First, I would like to comment on a small,
uncontrolled, unscientific research effort at the University of Pittsburgh
Medical Center Health System regarding terminology. As you all are aware,
the terms "complementary and alternative," and "complementary and integrative"
have, on occasion, elicited not very subtle reactions, both pro and con, from
the public and health care workers.
Therefore, we conducted a consumer survey
for an indication of what patients seeing physicians in our health system
preferred our program to be called. As a result of this survey, we call
our program the Health Enhancement Program. Our program, which is a
top-down, trustee-driven, approved program by the trustees of the Health Center,
will incorporate validated alternative approaches and components of behavioral
medicine, and conduct research studies to determine the appropriateness of
modalities not yet validated.
I am a psychoneuroimmunologist, and I work
with the mind-body connection, the subject the panel was asked to address.
I study the effect of psychologic stress on the brain, how the brain's response
to stress alters the function of the immune system, and how altered immune
function influences health. I will briefly comment on three areas of
research concerns related to mind-body interactions: safety; standardization;
and controls.
Safety. Mind-body interactions often
promote enhanced coping with stress. Massage is a modality utilized for
this. Massage is unlikely to cause harm when applied by well-trained hands
that have received the appropriate certification from the appropriately
certified schools of massage.
Imagine feeling tired with some lower-back
pain, just the conditions that massage can help a patient with. That is,
unless the patient has multiple myeloma with destructive bone lesions, and as a
result of too vigorous a massage, suffers a bone fracture. Certainly, a
technique can be safe. However, only if the subject and the technique are
properly matched. In the example, they were not.
What if the same patient had sought a
therapeutic touch practitioner for their tiredness and low-back pain.
Certainly, there would be no concern of fracture, only the concern of time lost
before proper treatment was provided. I cannot emphasize strongly enough,
due to the increasing numbers of patients seeking non-standard approaches to
health, that it is essential to have proper medical evaluation before embarking
on a procedure that superficially may appear to be safe but that may do harm or
delay proper treatment.
How will research into the formulation and
implementation of guidelines for safety be established? I suggest the
answer lies in traditional and non-traditional practitioners working together to
merge their specialized skills into a consumer safety program. Formation
of collaborative panels of experts is encouraged to develop such guidelines.
Standardization. Many arguments take
place regarding the appropriateness of standardization of alternative
modalities. Alternative practitioners claim their techniques cannot be
standardized because different patients require adaptation of the modality to
the characteristics of the particular patient.
Traditional practitioners desire
standardization within large-scale clinical trials to determine the
effectiveness of a procedure. Both approaches are correct, indicating the
complexity of the subject. However, my concerns regarding standardization
addresses the recipient of the treatment, not the treatment itself, and this was
just alluded to by Dr. White.
Applying the same modality to individuals of
different personalities and emotional characteristics may yield different
outcomes, as we do not know the personality characteristics of someone who is
likely to experience a placebo effect.
Certainly, the mind-body health connection
may decrease the symptoms of disease because the patient is made to feel better
and tolerates their condition better. However, we also need to determine
whether having an enhanced sense of well-being has an effect on the pathologic
basis of disease by altering the concentration of stress hormones in tissue and
plasma.
Cell trafficking patterns, adhesion molecule
concentrations, protein synthesis, and even stem cell maturation, may be altered
by effects on catecholamine and glucocorticoid plasma concentrations as a result
of belief in an alternative modality a patient is experiencing.
Meaningful research is not going to occur
through study of non-standardized approaches of individual patients and
anecdotal reports. Large studies of standardized approaches in
well-characterized patients are needed.
Some of the characteristics of subjects we
are concerned about that may influence these sympathetic nervous system and
hypothalamic pituitary adrenal axis responses to alternative interventions, and
may contribute to understanding why the interventions work for some individuals
and not others, are: Is the subject high or low in optimism, anger, hostility, a
sense of humor, perceived stress, social support, religiosity or spiritualism,
and physical fitness; has the subject tried and been disappointed in traditional
medical care; is the subject high or low in their opinion of CAM; does the
patient have a good relationship with their physician, or have they been
dissatisfied with their physician; does the subject practice meditation or yoga;
does the subject expect the procedure to work.
Knowing what works and in who it works is
essential. A patient requesting acupuncture who has characteristics that
are found, through proper research, unlikely to be associated with a therapeutic
response, can be directed to a therapy more likely to provide a therapeutic
response, thereby saving time and money for both the patient and health care
practitioner.
For example, would research find that a
subject who was high in hostility, low in optimism, low in expectations of a
possible outcome from a procedure, sedentary, and lacking a sense of humor, be a
likely responder to acupuncture.
Controls. Whenever possible, control
groups should be studied to provide a means of evaluating CAM treatments, alone
or in combination with conventional treatments, and compared to standard
treatments or to no treatment.
Certainly, blinding a practitioner or a
subject to whether or not actual massage or acupuncture was being applied is
difficult. However, in the area of mind-body interventions, institutional
review board requirements are also a problem.
For example, assume that a study is being
performed of the effects of a stress-coping program on the progression of
MRI-documented plaque size in the central nervous system of patients with
multiple sclerosis. Patients are recruited to the study and sign an
informed consent appropriately indicating that they will either receive the
intervention or be randomized to a weightless control group.
However, the control group obviously knows
that they are a control group, and that if the intervention works, they will be
able to participate once the study is completed. This expectation and
knowing that they are part of a study may produce a positive placebo effect.
The proper control would be patients who did
not know that they were part of a study, believing the MRI was being done as
part of routine management. However, that could be deceptive and not
allowed.
Thus, proper research studies of the
influence of mind-body medicine on alteration of the course of disease may
require a modification of IRB criteria or the design of innovative clinical
trials that are developed by meaningful collaboration between alternative
practitioners and well-trained clinical trial interventionists.
In conclusion, in the absence of strong,
empirical data to support many CAM interventions, it is important for CAM
clinics and practitioners to put a mechanism in place to systematically obtain
baseline and objective outcome data on the clinical condition of the patients
they treat. Subjective outcomes, without knowing that the course of a
disease has been modified, will not help to end to the differences between
traditional and non-traditional practitioners.
Detailed assessment of the patient's course
of disease, including changes in symptoms, objective disease measures, and
laboratory parameters, should be monitored and recorded in accord with
guidelines that will allow the data to be published in peer-reviewed journals.
As I have stated, collaboration between
traditional and complementary practitioners is needed to enhance the safety,
standardization, and use of proper controls for studies to establish the
appropriateness of integration of CAM into conventional health care.
CAM practices have a past, present, and
future. The health care industry, the academic community, and CAM
practitioners in and out of the academic world, should advocate for and pursue
advances in the practices of scientific and humanistic medicine. This will
occur through open communication and mutual respect.
At present, the public both demands access
to and frequently utilizes CAM treatments. These treatments appear to
offer something that patients want and presumably may not be receiving from
mainstream medicine. Both patients and CAM practitioners believe that the
good in these treatments usually clearly outweighs their potential for harm.
The challenge is, therefore, to offer such
treatments to patients while carefully monitoring their use, subjecting CAM
treatments to empirical study, using accepted methods of scientific inquiry, and
making every effort not to mislead patients or the public. Thank you.
Panel Discussion
DR. GORDON: Thank you all very
much. I really appreciate the thoughtfulness of testimony.
One of the things I thought we might do is
send you all copies of each other's testimony, plus a couple of papers that we
have from Andrew Vickers at Memorial Sloan-Kettering that might be interesting
on the same subject, because we really feel this is an ongoing dialogue.
I also just wanted to thank you, John
Chabot, personally for your work with the Gonzalez trial, and also with a
patient of mine who consulted you. I just wanted to say that publicly.
DR. CHABOT: Thank you.
DR. GORDON: Questions. Tieraona
first, then Dean, and then Wayne.
DR. LOW DOG: It is hard to know who to
ask questions because you were all so good. Anybody who would like to
answer, but perhaps Dr. Angell.
Thirty years ago, we were confronted with a
similar sort of situation with OTC remedies when, basically, we had no
randomized trials. There was very little evidence of benefit, yet all
these products were out on the market. They got a group of experts
together to try to sift through if there was a reasonable certainty of safety or
a reasonable certainty of efficacy.
Keeping in mind that these are for minor
self-limiting conditions -- I'm not talking about heart failure or things like
that -- under the current situation that we have with DSHEA, would you be in
support of a group such as the National Academy of Science or another group, an
expert group, trying to set up a panel that would look at things that seem to
have a reasonable degree of safety or a reasonable degree of efficacy for minor
conditions, which, many of these supplements are used for? Do you think
that that would be a step in the right direction, or not?
DR. ANGELL: Well, as some of the
speakers said yesterday, I think the major problem is DSHEA itself and the
herbal remedies, the dietary supplements, the so-called dietary supplements,
should be subjected to the same standard as any drug. That is, the
manufacturers should be required to show safety and efficacy before they are
marketed, and not afterwards.
As for panels, if a panel gets together, an
expert panel, and looks at the scientific evidence that is out there, I am all
in favor of that, of sifting through it, but panels tend to take on a life of
their own and go beyond the evidence that is out there, and then it becomes
ex-cathedral pronouncements, and they are of no particular value. You
can't reach a conclusion without the evidence.
DR. LOW DOG: I guess my problem always
comes to things such as chamomile tea, which you can get at the village in or an
restaurant. We had it last night.
At what point do all things have to be
tested for safety and efficacy, when some of them are not foods but they are
clearly not the potent medications which so many companies do sell?
DR. ANGELL: What is the medicine and
what is the food, you are saying. Obviously, that is going to be a fairly
fuzzy boundary. I think the first question is, is the substance in the
thing that is labeled as having the substance in it. So there are two
different questions. There is standardization. There are standards
of purity and concentration and so forth, and there is effectiveness.
If the chamomile tea really is chamomile
tea, it would depend on what evidence is out there -- and I don't know -- about
any adverse reactions and so forth, but you can get silly about this. I
agree with you. You have to draw the line in a sensible place.
DR. GORDON: Let me just go through the
list and make sure I have everybody. I have Dean, Wayne, Ming, Joe
Pizzorno, George DeVries, and George Bernier, and Joe Fins.
Dean.
DR. ORNISH: I also want to thank the
panel for its very eloquent testimony, and to say that I think many of us are of
like mind, but I also have questions because one of our charges is to make
policy recommendations. We hear from a number of people that there should
be an increase in funding or there should be an increase in research. So
this first question is directed to Dr. Angell.
Do you support an increase in funding for
the National Center for Complementary and Alternative Medicine?
DR. ANGELL: I have a problem with that
center to begin with, because I don't believe that there should be two kinds of
medicine. I think that CAM practices for which there is preliminary
evidence, a lot of anecdotes, well-documented anecdotes, or CAM practices that
are already in widespread use, need to be studied. That you need a new
center to do it, I think, is arguable, and I would argue against that.
The current institutes can study any kind of
treatment they want for any kind of scientific question they want. And so,
if the hypothesis is that homeopathy is good for heart disease or whatever,
being more specific than that, then I would think that it would be studied
within the National Institute of Heart, Lung, and Blood.
So I think that this increases the
separateness of it. It is as though there were two kinds of medicine,
which I argued against in my statement. Instead, there ought to be
medicine that has been tested, and medicine that hasn't, and it ought to be all
in there together.
DR. ORNISH: I have quoted your
statement many times, because I agree with it in theory, but in practice, if
that were true, then those studies would already be out there. We have
heard from a number of people, almost as a refrain, that in the conventional
institutes, the NHLBI or whomever, at least certainly in the past, it has been
very difficult to get studies funded that are not within the conventional
paradigm, and for that matter difficult to get them published in leading
journals like the New England Journal and others, or that they are held to a
different standard.
De facto, if it were possible to get these
studies funded at the conventional institutes, there would be a much broader
literature already out there. People say, well, these interventions don't
have any science, but then it is very hard to get these studies funded.
DR. JACOBS: Can I just make a comment
as a researcher in the field? And that is, the whole area of research and
funding changed dramatically with the establishment of what was then the Office
of Alternative Medicine.
Before, when I was knocking on the doors at
the University, people thought I was some kind of lunatic. Once the OAM
was established and there were calls for paper and there were funds available,
all of a sudden, people were willing to collaborate and to take it seriously.
I agree with you that none of the research
that we have in the past, and very little of it in the past 10 years, would
exist if it hadn't been for the NIH office. I think it is very important
that it grow, because even with the small amount of funding it has now and so
many different modalities, a good homeopathic research study in otitis media,
which is one of the areas that it is reputed to be good for, we have estimated
would cost $3- to $5 million. That is maybe a tenth of the budget of the
whole NIH centers. So clearly, we need more funding.
DR. ANGELL: The way research is funded
and the attention that different things get has to do with a lot of factors, one
of which is the public concern about the ailment or the treatment. You
could name almost any disease or any treatment that somebody would argue had
been underfunded at some time. For a while, people thought that breast
cancer was underfunded. Now people argue that prostrate cancer is
relatively underfunded.
So that there is always a group that would
like to see more money put into something. The problem with talking about
CAM in general, as I said at the outset, it is so disparate, and not everything
can be funded. There is usually some prior probability that it might work.
One would say that the claims of a large
study of St. John's wort are very much higher than the claims of a large study
of therapeutic touch. So, which of those things are you talking about?
You can always complain that something is
being underfunded. Scientific knowledge changes. So that, for a
while, everything is going into AIDS because it is, scientifically, so
interesting, and then it switches.
I don't see why one should bundle all of the
CAM practices together and say it should be treated separately and specially.
DR. RABIN: The problem is not the
institutes; the problem is the reviewers in the process. For those with,
that I am sure many of us had, years of experience on study sections, there are
biases which come into the review process.
To make a level playing field, this
institute was created, but once the playing field is level and there is fair
review and qualified reviewers of CAM procedure on study sections, or study
sections set up for this within the existing institutes, then this may not be a
problem, but I think right now, there certainly is a bias. We dealt with
that in psychoneuroimmunology for many years, until we were able to get adequate
reviewers on study sections.
DR. ORNISH: Just one follow-up
question.
DR. GORDON: Quick, because we have a
lot of other people.
DR. ORNISH: Then, why don't we come
back if there is time.
DR. GORDON: Okay, great. Thank
you.
Wayne.
DR. JONAS: How many questions?
DR. GORDON: One.
DR. JONAS: One question?
DR. GORDON: One per person.
DR. JONAS: All right, one per person.
I want to thank the panel. I thought
this was an excellent series of presentations. I thought it was very
consistent with the previous presentations that we had, and I am supposed to be
heading up one of the discussion groups on research methodology a little later
in the day, and from what I can tell, it is going to be extremely easy because
there appears to be a consensus that we have good research methods that now
exist, that we want to use good research methods, and we just need to start
applying them to these areas and letting science take its course.
I want to especially thank Dr. White for
pointing out the variety of research methods that exist for different purposes
and that are good. I think it is important that we look at and use all
those research methods for those different purposes.
Let me mention that there was a third
methodology conference that was held, you may not have known about, that may be
of interest on histomology, which did not get published at the OAM.
Which question to pick.
DR. GORDON: Like Gertrude Stein,
right?
DR. JONAS: Yes, that's right.
The only area that I don't think, really,
has been addressed is the plausibility issue, and Dr. Angell, you addressed
that. I was pleasantly surprised and pleased to see that you were willing
to say, if there is no plausibility but if it is largely used by the public, we
probably need to investigate it in some way. I think we are coming even
closer on that issue, and could perhaps set up some criteria to decide when
those conditions exist.
I would like to ask Dr. Chabot why a
randomized, controlled trial was decided on in the first place. When I was
getting my evidence-based medicine training up at McMaster University, and Dr.
Sackett was up there saying, this is what you do, and this when you do a
randomized, controlled trial, et cetera, the example they always used, when you
do not need a randomized, controlled trial, was pancreatic cancer. I
taught that for years to my students. Yet, when we actually have the
opportunity to do an integrative therapy for pancreatic cancer, that is the
first thing that is attempted.
I am just wondering what the background, and
why was it that that was selected as something that needed to be done at the
time.
DR. CHABOT: I think the best answer to
that goes back to your first comment, plausibility. When you look into the
treatment, identifying physiologic relationships that should allow this
treatment to be explained, I can't come up with a mechanism.
So we then have to go back to, how can we be
absolutely sure we are going to come to a conclusion based strictly on
empiricism that this works, and I think the best trial designed to do that is
the trial design that eliminates all bias. A randomized trial is certainly
the easiest way to do that, and the way that is most unimpeachable when you
present the data.
In thinking about presenting this
information, once we have collected the data, there are ardent supporters and
vigorous antagonists to this treatment in particular. My hope was to
develop absolutely unimpeachable data to bring both of those camps together and
say, yes, this is the answer. A randomized trial is the way to do
that. As we went forward, it became quite clear that we were not going to
come up with any data if we insisted on that design.
The new design will be attacked when the
data becomes available, and there will then still be ongoing discussion: Well, I
can't accept it because of this; because the control group wasn't quite right;
because this patient didn't match that patient quite perfectly; because we
disagree on what the stratification should be. In order to get the trial
done, I think we have to accept that.
DR. JONAS: It was really patient
preferences that didn't allow you to do the controlled trial, right? They
just wouldn't be randomized into it.
DR. CHABOT: Correct.
DR. JONAS: My understanding from the
case you presented is that it looks like it doesn't actually cure the cancer in
any case. The cancer was still there, and just something else was going on
that allowed these people to live longer. Is that correct?
DR. CHABOT: That particular
individual, certainly. The other explanation for this phenomenon is
selection bias, which, it is very clear in running this trial now for a couple
of years, that this patient population is different, and therefore the control
group we select has to be selected very, very carefully. Again,
randomizing is the easiest way to do that, but hopefully not the only way.
DR. JONAS: [Off mike] -- that it was
belief and plausibility that prevented this trial, because I looked at this data
from Nicholas Gonzalez when I first came to the OAM, actually, and also was
impressed that there was something there and it ought to be looked at. I
was severely resisted at the NIH until there was some gentle congressional
influence, which then, finally motivated the NCI to fund it.
Whether that turns out to be worthwhile or
not, who knows, but I just thought I would illustrate that for the Commission.
DR. GORDON: Ming.
DR. TIAN: A question for Dr. Angell.
Thank you very much for your
presentation. You mentioned that methodology, you think there must be one
standard. I just wanted to share information with you about NIH research
on acupuncture. In 1974, NIH did fund an acupuncture study using
double-blind study to evaluate the efficacy of lower-back pain.
Unfortunately, after a three- or four-year study, the conclusion was that in the
control group it was 45 percent is effective, and in the treated group, it was
55.
So the conclusion was acupuncture was not
effective, it was placebo. That was pure, scientific design, until 1997,
which, it was sponsored by Dr. Jonas -- the second meeting was November -- that
they then reviewed all the data and noticed that methodology is quite
important. Now acupuncture is positively accepted because of a lot of
scientific evidence to show it works.
My question for you is, do you think we
should develop methodology for CAM? For instance, like acupuncture, there
are no such sham points. Is that necessary to develop the methodology?
DR. ANGELL: I'm not sure I understand
the question. You are saying that there are no acupuncture points that are
not valid, according to the theory of acupuncture?
DR. TIAN: No. My question is, if
we use traditional methodology to evaluate acupuncture, we might fail, so we
have to be very careful to at least use a newly developed methodology and have a
well-controlled group to study.
DR. ANGELL: I can't speak to the
details of this because I am not quite sure about the study that you are talking
or what you are alluding to, but when I said the same methodology, what I meant
was the application of the scientific method, to have a hypothesis, that this
will, in this condition, do this to; to have verifiable outcome measures; to
collect verifiable data; to draw the conclusions based on the data.
Within that overall requirement for the
application of the scientific method, of course there will be differences in the
details of the methodology, depending on the question that you are asking and
the modality that you are testing. There has to be.
In something like, I gave the example of,
fetal stem transplantation for Parkinson's disease, there is a lot of trouble
knowing what the control group should be, what the sham procedure should be,
whether it is ethical, for one thing, to do a sham procedure.
So there can be difficulties, but I don't
think they are unique in CAM. I am not persuaded that they are unique.
DR. GORDON: Thank you.
Joe.
DR. PIZZORNO: Dr. Angell, you present
an interesting challenge, because on the one hand, I agree with most of what you
have to say and believe that science is indeed the pathway, not so much that we
prove our efficacy, but by which the practice of medicine gets better.
On the other hand, we seem to live in very
different worlds, and I hear some perspectives from you of CAM being simply
modalities or therapies, which is a gross simplification. I also hear your
perspective about what conventional medicine is that is not, apparently, shared
by most of the patients out there who are choosing to go to CAM professionals.
I think one of the big challenges here is
that what really differentiates natural medicine from conventional medicine is
more of a philosophical approach to our patients, how we think and interact with
each other. That, I think, needs to be tested, and I think that that
different approach to the patient, which is much more patient-centric than
disease-centric, is why patients come to see us.
Is there some way we could design a study to
look at that very factor, not the theories, because, like you say, there is lots
of research that can be done there, but rather the different experience that
patients have going to conventional versus CAM providers, and learn from that
about ways in which we can improve medicine?
DR. ANGELL: Well, if that is a general
area that you would like to study, then you have to develop a hypothesis that
can be tested, and design a trial that will test it, and collect verifiable
data, and draw the conclusions, and only those conclusions, that flow from the
data, just as you would if you were testing anything else, but you have to give
me, not a vague hypothesis, but a specific hypothesis that can be tested.
DR. GORDON: Alex White, and also Bruce
Rabin, you addressed this some in your testimony, so we would welcome hearing
from you.
DR. WHITE: At the Oregon Center of
Complementary and Alternative Medicine, we don't get at this directly, but I do
think we get at some of the issues that you have highlighted.
Developing an acupuncture protocol was
actually very difficult because many of the people with whom we are working,
when we ask them to develop a standardized protocol that can be used in a
clinical trial, it is incomprehensible. It is not something that they are
used to doing. It is an individualized treatment approach. The
acupuncture points are modified based on patient response and examination, and
if we ask them to identify 20 points that can be used in a trial: Why would I do
that, because it doesn't make sense; My colleagues wouldn't believe it.
What we have tried to do in designing our
trial is to provide some flexibility in our studies, with some core acupuncture
points, but allowing there to be individualized within the context of the
clinical trial.
In particular, one of our studies is
actually evaluating more of the system approach. We have a trial that
looks at traditional Chinese medicine and naturopathy for women who have
multiple medical problems and chronic facial pain. We haven't specified
that X,Y, and Z happens within the context of that trial. We would rather
randomly assign these women to these particular intervention arms.
Within the context, we know what happens and
we have tried to put some balance on it, but it generally is evaluating the
system of care rather than a particular intervention.
The hypothesis is different because the
hypothesis then becomes not whether acupuncture point X,Y, or Z is the right
point, but rather, is the system approach and the holistic approach
important. That is what we are testing, essentially, rather than the
individual components that may make up traditional Chinese medicine or
naturopathy.
DR. RABIN: I wonder if part of the
study which you are suggesting, looking at interaction between patient and
practitioner, wasn't already done historically.
There was a time when the patient went to
the physician. The physician knew about the family, the personal problems,
the work problems, the stressors in their lives, and that interaction had,
possibly, a positive effect on health, and that is gone. The time is gone
where practitioners can get to know the patients like that.
I think history would say that you are
correct, that reestablishment of that relationship -- and a lot of what you are
doing and the beneficial effect of what you are doing, is reestablishing that
relationship -- it would be extremely important to take a look at it
again. If it indeed is shown through the proper scientific studies to be
important, to try and reestablish that.
DR. GORDON: Joe Fins is next -- no,
I'm sorry, George is next.
DR. BERNIER: Thank you, sir.
DR. GORDON: Thank you. I stand
corrected.
DR. BERNIER: I have a question for Dr.
Jacobs.
In the minds of many, evidenced here today
and in a lot of the discussion that has happened over the last year, many people
believe that it will be the clinical trial, one way or another, that provides
the answer for a lot of the issues that are being discussed.
In your statement, you indicate that an
important tenet of homeopathy is individualization, whereby each person is
treated with a specific remedy which fits his or her unique pattern of physical,
emotional, and mental symptoms. For this reason, different people with the
same diagnosis may receive one or several different homeopathic remedies.
The implication is that it can never be tested by the conventional clinical
trial way.
It makes me think of Dr. Bernie Fisher, who,
back in the 60s and 70s was able to start a program, whereby surgeons, present
company excepted, at that time, weren't terribly interested in finding out what
would happen to a population of 100 people. They were just focusing on
one.
That is a long-winded question. I
guess what I want to ask is, looking down the road, can you see really valid
clinical trials being conducted on a regular basis to test homeopathy?
DR. JACOBS: Well, actually, there have
been many clinical trials that I believe are valid that have tested
homeopathy. There are several ways to do this. I actually mentioned
these in my comments, but perhaps I was talking fast. The studies that I
have done have all been RCTs, where patients are randomized to either receive a
homeopathic medicine or a placebo.
So we are testing the patients as a whole
who received homeopathy, even though they may have received different
individualized medicines, versus the patients who received the placebo.
This, of course, has been criticized. In some circles it is seen as what
they call the "black box effect," whereas, you put people through a certain
system and compare that to placebo.
There are other ways that the RCT has been
adapted to homeopathy. One is by selecting only patients who fit a
specific homeopathic remedy picture for a specific disease. There is a
study of fibrositis that was done in England in the late 1980s, where only
patients were prescreened to see which ones fit the remedy picture for Rus Tox,
which is a homeopathic remedy which is commonly given for arthritic and
rheumatic conditions.
And so, only those patients were enrolled in
the trial, and those patients then were compared to placebo.
And then, the third approach is to use
homeopathic combination remedies, which are those that are sold over the
counter. You can buy them in health food stores today, teething tablets,
homeopathic cold medicines, where they have the five or six most common
homeopathic medicines for a particular illness.
In our diarrhea research, we found that 80
percent of the children had only five remedies that were indicated, five
different remedies were indicated in 80 percent of the children.
Theoretically, a combination medicine with those five medicines should help 80
percent of people. So a trial could be done of that combination versus
placebo.
I think this is true for other areas of CAM
research, too. There are ways to use individualization and still stay true
to the RCT methodology. I think it is very important because it is the
gold standard that we do this.
DR. GORDON: Please, John.
DR. CHABOT: May I make a very brief
comment? Dr. Bernier's allusion to surgical research opens the opportunity
here.
I think, in many ways, the history of
surgical evolution and research is somewhat similar to the current dilemma in
CAM research, in that, the surgeon-patient relationship is very, very
individual. The intervention is considered massive. The thought of
randomizing between an operation and medicine, most patients will usually favor
taking a pill rather than undergoing an operation.
But thinking about current surgery for
breast cancer is the ideal example. There were strong advocates of
mutilating operations in the past who felt fervently that the right operation to
do was a radical mastectomy for breast cancer, and the only operation to
do. It is only through long years of well-designed and implemented
clinical trials that most women now undergo breast conservation surgery for
breast cancer.
Very difficult to do; it took a long time,
and it was only through good science that we have achieved the state where
amputations for breast cancer are not done.
DR. GORDON: Thank you.
Joe Fins. We are already over time,
and I want to do our best to give the three people who haven't had a chance to
ask questions the chance. So, Joe, please.
DR. FINS: Dr. Angell, and the panel,
thank you all for your comments. I want to follow up Dean's question to
its logic or illogical conclusion.
When he asked whether you would want to
increase funding for the NCCAM, you said no, but based on what you have said, if
there would good hypotheses that were worthy of extramural funding, you would
say that would be appropriate.
I think there is an implicit statement or
idea in what you said about the value of integrating these studies in the other
institutes because it would foster integration, but at the same time, there are
biases in the other institutes against these kinds of hypotheses and some of the
questions that are out of the Cunian paradigm that they are used to living in.
So in an ideal world, we would have it
dispersed through all the institutes, maybe a quota system of certain kinds of
funding. But, practically, how do we get there from here? If the
term is not "complementary and alternative," but it is "integrative medicine,"
how do we have an integrative research system on the federal level, and maybe
seeing NCCAM as a transition item into a more integrative approach? How do
we get there from here?
DR. ANGELL: Well, it may, in fact,
turn out to be a transition, although any organization to become dedicated to
its survival. So that, I am not so sure that it, in fact, would play out
to be a transition.
Here again, the implication of your question
is that CAM is all one thing. I think there is often resistance to a new
type of treatment that is proposed. We just heard about lumpectomy versus
mastectomy; tremendous resistance, but as the science comes out -- and it may be
very slow at first, and there may be biases that have to be overcome -- the
successes will make the next one easier, and the next one will be easier.
That is just the way clinical science progresses. You can't do all
overnight.
Some of the CAM treatments, and I think the
herbal remedies are the most promising, will turn out to work, to be confirmed
in scientific testing, and will be incorporated within standard medicine.
Others will die, and should die.
So I don't want to see it marginalized by
being lumped together. I want to see it treated on its merits.
DR. FINS: The implication here is that
separate is not equal, and that the maturation of the field will be when
investigators, who maybe today are considered CAM investigators, are applying to
the other institutes for funding and they are viable.
DR. GORDON: One thing I want to point
out that Steve reminded me of, is that there is considerable and increasing
cofunding of some of these studies by NCCAM and some of the other
institutes. So I think that is an important development.
DR. WHITE: I would just add to that
that it is not only the support of research itself, but it is support of
education and training, and creating a cadre of CAM researchers, which I think
is important. It is a sort of Catch-22. I think the ability of other
institutes to take risks on funding CAM -- "risks" might not be the right word,
but my sense is that some directors would say that it is a risk -- of funding
CAM therapies is because there is not good science.
Well, you are not going to get good science
until you get the funding, so which do you do first, to the extent to which good
science, then, will lead other institutes to feel like it is less risky, that
there is a clear methodological basis for these therapies. I think that
NCCAM goes beyond simply funding research, that the infrastructure piece is the
education and training, developing a cadre, developing a research agenda in CAM.
I certainly agree that CAM is not a uniform
therapy, but there are things go beyond simply funding RO-1s.
DR. ANGELL: Except that advocacy
should not get ahead of the science.
DR. WHITE: I would agree with that.
DR. GORDON: Bill.
DR. FAIR: I, too, would like to thank
the panel. Having, until recently, spent 16 years at Memorial
Sloan-Kettering, I know Nick very well and was impressed by the tremendous
practice that he had. I also had the opportunity to review his manuscript
and submission to a journal, not the one it was subsequently published in, and
the problems that we had were several, and I wanted to know whether you had
surmounted these problems.
First of all, was, out of this huge
practice, he had 11 patients that he reported on. Quite honestly, we could
never get the denominator of the patients that he saw.
Secondly, the Kanusky Performance Status was
not listed adequately. Across the board, almost any clinical study in
oncology, as you well know, the best predictor of response, is going to be the
Kanusky Performance Status going into the study. That is almost axiomatic.
The third was, he was using his hair
analysis to alter the treatment. I think that that was pretty much put to
rest. You can't judge the effect of cancer therapy by hair analysis.
So my questions were, have you been able to
sort this out? As a surgeon, I would like to say one other thing to
support what you said. It has often been said that had we waited until all
the mechanisms and the responses and what flavored it and what inhibited the
immune response before doing a transplant, we would still be waiting to do the
first kidney transplant.
So I think this goes along with what Dr.
Angell said, sometimes you don't have perfection when you do things.
Typical surgical analysis: Just don't stand there, do something. So I
think that sometimes we have to do these studies, even if we don't have what
would fit the perfect statistical study, and obviously that is what you are
doing there.
DR. CHABOT: First, let me address the
hair analysis. It has no role in the clinical trial. It has been
demonstrated not to be effective. It was never part of the clinical trial
and has no role in guiding therapy.
I do not know the denominator for those 11
patients. The two answers to this, the 17-month median in 11 patients, it
is either selection bias, which is a very real possibility, or it works.
There aren't very many other plausible answers to this question.
I think that my review of the data convinces
me that they were real patients, they had the correct disease, they had the
correct stage of disease, they were followed carefully and the data are good
data. But selection bias is a very real possibility and I think that is
the concern that you raise.
To try to go back and answer that question,
look at that pilot trial and think about how many patients did 11 come from, I
think we would still be arguing about this, whether it is real or not. So
we just designed a trial to answer that question. That very specific
hypothesis really is, is this selection bias, or is this a real phenomenon.
DR. FAIR: We were just asking, okay,
Nick, in the course of a year, how many patients did you see with pancreatic
cancer; you have been doing this for X number of years, so X times X should give
us the denominator, and it was not possible to get that information.
DR. CHABOT: Today, Nick is not seeing
any patients with pancreatic cancer. He is referring all of them to the
trial, and we are screening them all. If they don't meet our screening
criteria and enter the trial, then they are free to see Nick independently, but
Nick will not see patients with pancreatic cancer without referring them to the
trial.
I do believe completely that he is following
that course of action.
DR. GORDON: I just want to say
something to everybody. We are already 10 minutes over. One of the
things that we might do is begin the small groups during lunch time, if that is
all right.
No, not all right? I'm sorry?
Okay. So not as good to do that.
So let's just have the last two questions, and then we will move on. Effie
next.
DR. CHOW: I want to thank the panel,
also. I have some comments, and I would like some comments from the
panel. We don't like the term "CAM" either. It is a dilemma within
itself, but using CAM, the dimensions that is very different, maybe you folks
can reduce that difference, is that many of the therapies utilize energetic
concepts, prahna, manna, toth [ph], chi, qi, whatever, and goes back to
Xioming's comment, there are no sham points in acupuncture. In touch,
there is no sham touch, either.
I think your psychoneuroimmunology is kind
of related to that very closely, and perhaps you could help us with this.
How do we then control the studies? For example, in distant healing, we
haven't mentioned distant healing. There is a great interest in that now,
and it is very effective; spirituality.
The thought is that once you think it, it is
so. So, how do you measure that? Dr. Samuel Rosen, the famous
audio-larynologist did a research on acupuncture. He used deep acupuncture
for real acupuncture, and superficial acupuncture for a sham. There, he
lost his control already, if we knew what acupuncture was, really.
Yet, they got results with the group.
They could talk behind them and they could hear, but their audiograms didn't
show any change. So, what about measurement tools, et cetera? I
throw this out. It is a real dilemma for us.
DR. RABIN: It is a very important
question, and, I think if we look at Michael Meaney's work, a question that
begins in utero. Certainly, we know from non-human primate studies that if
a pregnant monkey is undergoing high levels of stress, that the personality
characteristics, the response of the offspring, the immune system function, is
permanently changed.
The Michael Meaney studies on touching and
stroking animals, and how that permanently changes the function of the HPA
access. We are learning that different personality characteristics in
adults are associated with different activities of the HPA access, and different
activities of the locus cerelius.
I think we are dealing with a very exciting
area where we are beginning to learn that the wiring patterns of the brain, that
the hormonal milieu that the brain produces with different emotional states have
physiological effects. Certainly, with our new understanding of why
individuals develop atherosclerotic disease and adherence of monocytes to
endothelium, and migration of monocytes into the subendothelial tissue, we begin
to realize that the hormonal composition of an individual is associated with the
disease.
Now, we spent a lot of time looking at
stress and anxiety states. We have spent very little time looking at
relaxation and spiritualism and stress coping, and the hormonal alterations that
that produces. If you say to somebody, like you are indicating, "You are
the product of distant healing," there are most likely hormonal alterations
occurring in the individuals which will be associated with the different health
outcomes.
We really need to begin to look at these
interactions, at the hormonal response to both well-being as well as stress, to
look at what it does, not only to immune system function, but to a variety of
physiologic functions. Placebos work for a reason.
The investigators are not putting in grants
to do this. We don't need separate institutes for this. What we need
are researchers who put in excellent grants. If you put in excellent
grants with the proper controls and the proper data analysis, these should be
funded. We do need to remove biases from study sections, but the money is
there, certainly, if we have the qualified investigators.
As has been indicated, we need to stimulate
more individuals to work in this area to understand these mechanisms.
There are powerful effects. We know that from epidemiologic studies.
We do need to learn more about mechanisms, and we need the proper trials.
DR. CHOW: Do you feel you have the
mechanisms in place, or do you think they need to be more developed?
DR. RABIN: We are beginning to learn
about some of the mechanisms, but we can only study what we know.
Certainly, we can study the sympathetic nervous system and the HPA access, and
we can look at substance P and neural peptide Y. There are probably other
systems out there that modify the hormonal response to stress, the hormonal
response to relaxation and health effects.
I don't think we know everything. We
started off with a few cytokines, and now there are 40 or 50. Every day,
there are more cytokines. There are many things yet to be
discovered. We have to do that to get
DR. GORDON: Thank you. I think,
as you can see from our response, we could probably go on all day. I
really appreciate, we all appreciate, your coming and your presentations, and we
hope we will be able to continue the dialogue. Thank you very much.
[Applause.] Panel VI: Training of
Conventional and CAM Investigators
MS. CHANG: We are going to move right
into our next session, so if Commissioners can stay where you are. There
will be a break after this session, we promise.
Nancy Pearson and Neal West, who are sharing
some time, Robert Blanks, Russell Phillips, and Richard Hammerschlag, if you
could join us at the speakers' table. Thank you.
DR. GORDON: Good morning,
everyone. We will begin with Nancy Pearson, please.
Presenter:
Nancy Pearson, Ph.D.
During the next several minutes, we would
like to briefly describe NCCAM's training initiatives for conventional and CAM
investigators. I will describe NCCAM's National Research Service Award
program, or NRSA, for research training, Dr. West will describe NCCAM's Career
Development Award programs.
NCCAM's ability to achieve its research
goals is dependent on the availability of a critical mass of skilled
investigators, both from the CAM and the conventional research
communities. These goals are consistent with the NRSA program. To
quote from an NRSA announcement, "Congress enacted the NRSA, or National
Research Service Act program in 1974 to help ensure that highly trained
scientists will be available in adequate numbers and in appropriate research
areas to carry out the nation's biomedical and behavioral research agenda."
It is under this congressional authority
that NCCAM awards individual and institutional NRSA training grants.
Through the NRSA awards, NCCAM is committed to providing funds for high-quality,
mentored research training experience for both pre-doctoral and post-doctoral
students who are interested in pursuing a career in CAM research.
Funding through NRSA research training
grants are available both to CAM practitioners who wish to gain knowledge and
experience to conduct rigorous research in their field, and to conventional
researchers and practitioners who wish to increase their knowledge and
experience in specific CAM research areas.
To do high-quality research that will
advance the CAM field and make a significant impact on the health care system,
both CAM practitioners and more conventional investigators need the same
rigorous research training. They need to acquire knowledge of CAM, but in
combination with a strong grounding in those disciplines necessary to do
high-quality, clinical, and basic research.
One useful paradigm for training students in
CAM is to include CAM-trained practitioners and researchers as part of the
training faculty, so they can bring their important, unique perspective,
philosophy, and experience to the training.
During the first year of funding, which was
Fiscal Year 1999, NCCAM spent 1.3 percent of its budget on training.
Training is defined here as the combination of NRSA awards and career
development awards. In Fiscal Year 2000, it increased that to 3.8 percent
of the NCCAM budget. During this fiscal year, that is 2000, NCCAM funded
seven NRSA individual pre-doctoral fellowships, two NRSA individual
post-doctoral fellowships, and two NRSA institutional training grants.
These two NCCAM institutional training
grants, which support a total of 12 trainees, combine broad-based research
training, both in CAM and basic scientific methodologies, necessary to perform
high-quality research in any scientific area. NCCAM also has committed
funds to support fellows on five institutional training grants sponsored by
other institutes and agencies, and these are called co-pays.
In addition to these official training
mechanisms, research training also occurs in our funded research centers in RO-1
grants, as you heard in the last session.
While many of the NRSA awardees come from
conventional research and educational backgrounds, these NRSA training programs
have begun to attract trainees with degrees, for example, in traditional Chinese
medicine and chiropractic.
The research and investigations these
students or fellows are pursuing are wide-ranging and cover many different CAM
modalities. These range from research on herbal remedies to treating
various disease conditions, to investigations of the social processes that lead
to the use of alternative medicine therapies to treat HIV, to studies of the
effect of static magnetic fields on fibromyalgia.
We anticipate that the NRSA training
portfolio will continue to grow in 2001. This growth will include the
awarding of two more NRSA institutional training grants and additional NRSA
individual pre-doctoral and post-doctoral fellowship awards. NCCAM has
also issued a request for applications and made available money to fund minority
researchers.
In conclusion, we feel that by providing a
wide range of training initiatives, we can encourage maturation of the whole
field.
DR. GORDON: Thank you.
Neal West.
Presenter: Neal West, Ph.D.
DR. GORDON: Good morning.
DR. WEST: The NCCAM Post-Doctoral
Career Development, or K Awards, are designed to ensure that continued mentored
research opportunities are available to help a select group of highly
accomplished individuals to make the transition to independent investigator
status.
The NCCAM is currently supporting 11 Career
Development Awards at a total cost of $1.3 million in Fiscal Year 2000, and we
expect to make several additional awards this year.
Three current awardees have the K-01, which
is the Mentored Research Scientist Development Award. This generally is
made to a Ph.D.-trained scientist seeking a mentored career development
experience in a research area new to the individual.
Two of our current awardees have the K-08,
which is the Mentored Clinical Scientist Development Award. This supports
the development of outstanding clinical research scientists.
Four of our NCCAM awardees have the K-23,
which is the Mentored Patient-Oriented Research Career Development Award.
This supports clinically trained professionals who have the potential to develop
into scientifically productive clinical investigators, focusing on
patient-oriented research.
Two of NCCAM's K Awards are through the
K-24, which is the Mid-Career Investigator Award in Patient-Oriented
Research. This program is intended to further both the research and the
mentoring endeavors of outstanding patient-oriented investigators. Both of
our current K-24 awardees hold both the M.D. and the Ph.D. degree. This
award enables them to expand their potential for significant contributions to
their fields and to act as mentors for beginning clinical researchers.
NCCAM Career Development awardees are
conducting research across a broad range of scientific and medical topics,
including botanical/drug interactions, studies of glucosamine and cartilage,
homeostasis and degradation, yoga in pregnant asthmatics, and a separate K, yoga
as a treatment for insomnia, Ayurvedic herbal effects on lipids and
atherosclerosis, the pharmacology of ephedrine/caffeine supplements, and in one
K-23 award to a chiropractor, the psychosocial behavior and immune factors in
back pain.
Since the CAM research community and CAM
research needs are so diverse, the NCCAM has made available to potential
applicants this full range of traditional NIH career development grant
mechanisms. The resulting successful Career Development awardees will
constitute an elite corps of CAM researchers who are further preparing
themselves to succeed within the highly competitive CAM research and NIH grant
environments.
DR. GORDON: Thank you.
Robert Blanks.
Presenter:
Robert Blanks, Ph.D.
I have been the medical educator and
researcher-scientist, for 23 years, at the University of California,
Irvine. I have had a lot of background in terms of chairing institutional
animal review committee for animal and human subjects. I currently chair
our IRB. I have had the privilege of being a researcher in what I would
prefer to term holistic, vitalistic modalities, focusing primarily
subluxation-based chiropractic, and one of its modalities, and a little bit on
Oriental medicine.
Throughout this time, it became very clear
that I was quite ill prepared to deal with the nuances of training.
Although I went through traditional Ph.D. training. I had trained medical
students, residents, and faculty in this for a many years, it became clear that
I had just one world view, which was the view of the RCT, the randomized,
clinical trial. This was the view I had. Until quite recently, I had
the privilege -- I won't say recently, 10 years ago, I had the privilege of
meeting a very talented man, who I believe was providing testimony
previously. I will get back to that in a second.
I had the privilege of talking with the
person who now had the benefit of having a holistic view of the world, a very
broad way of looking at health, and said, basically, I don't want to deal with
symptoms in dealing with my modality. I don't want to deal with outcome
measures which are not honoring that human domain. We need to come up with
very valid measures of health, which could include quality of life, which
measures the full dimension of health.
At that point, my colleague pointed out that
there are many different models, and I was to go back to the table, redevelop
myself, redesign myself. So I began to research the process. About
that same time, we developed a center, the Southern California Center for
Complementary Medicine at the University of California, Irvine, since renamed.
We came up with an interdisciplinary
approach, which talks to the specifics of the details of the committee today,
which is basically how we deal with design of research, how we move cultures of
evidence forward, and particularly what we are doing with the mind-body
construct in a holistic or vitalistic approach to health.
The first team member we added then was a
medical sociologist. We brought in an anthropologist. We brought
people doing psychoneuroimmunology. I was physiologist-trained at that
point, and also medical people that brought in other people who were trained in
specific disciplines. Indeed, we developed a health, wellness, and
quality-of-life outcome measure.
It is now an 87-item questionnaire,
validated in three separate samples, including a nutritional co-therapy sample,
giving us a way of looking at this process of health, defined not specifically
as a disease-oriented modality, disease treatment modality, but certainly
embracing the broader constructs of health.
Let's come back to this issue of the world
view, and this is indeed what we call the biomedicine model. I think there
is no question that this is the dominant culture. I think there is no
question that randomization does help with the issue of bias and so forth, but
let's think of the problem at hand in dealing with these health modalities, and
particularly those which are very vitalistic. I think the issue there is
how you merge this culture of evidence, particularly at the lower levels, merge
it to the higher level, which might be the RCT.
One of the things that I preferred to do, is
when I trained medical students to deal with investigators, is deal with this
issue of training, that various models are out there, and I will just name a
few. I gave handouts here, and you will see that there is a summary of
what I consider the dualism of the world views of research and research
training. In general, the biomedicine model seeks to classify, diagnose
and treat, largely, symptoms.
There are other models. The one that
is transitional now is one we call a social epidemiological model, which looks
at the disease entity within the context of the broader social domain, which is
often that person's socioeconomic condition, socio-behavioral condition and so
forth. We are dealing with many of the other issues that have come up
here.
Here is the last one, which is on the right
side of the column, for the benefit of the handout here, the one I just termed
the "social science model," but it is one that is often referred to as the
holistic or the contextual model, which looks at the person, their bio, mental,
social, and spiritual domain within the context of the society, defined broadly.
Now, we believe that in the first search for
the various outcome measures that might allow us to address these broad domains
of health, that we first sought the quality-of-life survey, which was the
patient's perception of health, or what we call "health belief."
In that quest, we largely found, and as most
of you may know, there are many quality-of-life scales, but many of these are
disease-oriented. There is a separate one for mental status, for
Alzheimer's patients. There is a separate one for the diabetic patients,
and so forth.
In each case, it focuses largely on the
disease domain, which is the ceiling of this. Either you have the disease,
or you don't have the disease. The cap is not the vital standard, which is
the human potential, but often is the absence of disease.
Going back again, as a quick reminder, in
1958, the definition of health by the World Health Organization simply said, and
it was really a brilliant discussion, that health was complete physical, mental
and social well-being, and not merely the absence of disease or infirmity.
We have picked up that definition. We
have sculpted a large part of our research outcome measures in health, wellness
and quality-of-life through surveys around that definition. Again, it
keeps away from the symptom, or what we call the biomedical model.
So we what could be classed as the three
models of the world view. I use this, too, because I like to think of the
dualism, like you have the yin and yang in the Oriental medicine
philosophy. Your best state of health in Oriental philosophy is the flow
of energy between the two extremes.
I believe that we need the flow of energy
between health outcome and research models, one being biomedicine as RCT, and
the other being more the social science model, and a very broad base of
literature looking at many characteristics, such as patterns, processes, the
context with which you are evaluating health, dealing with tracking entire
rivers of information, as opposed to collecting facts and so forth.
Well, as to specific ideas and how one could
proceed in the training, I believe the first starting place is to have dialogue
among interdisciplinary groups, and beginning at very early levels so we don't
become arrested in our perspective. We always want to keep an open mind.
In addition to teaching medical students, we
also have courses in biosociology, talking about the various models for
pre-medical students, which I would encourage you to think about, this idea of
inculturation, particularly with research, occurs very early in the training.
In terms of research design, I think we have
to be always very attuned to the fact that many of the modalities that, I think,
people often refer to as a CAM are actually very specific. The field of
chiropractic, in my opinion, has many different fields within it. There
seems to be two dominant cultures, the musculoskeletal, and then the group that
I prefer to relate to is just more holistic, and that is called the
subluxation-based approach. We need to understand this. We can't
view all those papers together.
I was glad to hear from my colleague, Dr.
Pizzorno, who I have never met, although it was very nice to meet you, that his
view of medicine at Bastyr is very holistic. I think we should have
naturopaths as triage people at every medical school, largely because they are
dealing with the patient within the context of the holistic discipline, not
simply dealing with drugs and medicines for treatment of disease.
I think we need to understand that we need
these broad measures of health. I am not going to hard-sell this idea of
health outcome measures using surveys, but I think we need to understand that
with multiple outcome measures, including disease entities, including various
other social contextual assays, and particularly the biopsychosocial measures of
health, we can begin to do multi-variate analysis, begin to subdivide the
variance, that is, the variability in the population would be subdivided by
specific outcome measures, using multiple analysis.
There is probably no time, but I concluded,
in this model that we have done now, with a second page where we talk about a
model for health based on the analysis of 3,000 people under care, in which we
have done path analysis, a very complicated statistical analysis to look at the
interaction between a specific modality, in this case, network spinal analysis,
which is a modality within subluxation-based chiropractic, and how that relates
to the patient's perception of health. Indeed, that model has been proven
now, model-validated, and it will be published very shortly.
Finally, I would just point out that, I
think, in terms of strategies for the Commission, I would certainly recommend
that we think about building interdisciplinary teams, that these might be funded
through various interdisciplinary approaches and interagency approaches, core
center programs, where, regionally, people can begin to develop cultures of
evidence about these modalities, and so forth.
Lastly, I think we are in the process of
building a certificate program for distance education, in which we hope to train
over the Internet, the Web, various modalities here, and begin to talk about
this at interdisciplinary levels.
Lastly, I would just encourage you that,
yes, indeed, I believe that we need more funding for NCCAM, largely because it
is --
[Interruption.]
DR. GORDON: If a coincidence exists,
that was a coincidence.
DR. BLANKS: This is not the federal
government saying no.
[Laughter.]
DR. BLANKS: The bottom line is I
believe we need a national institute to respect this broad, holistic view that
NCCAM brings to the table, largely to increase the dialogue, and largely to
increase the lower levels of the evidentiary base so we can bring these things
and percolate them to the top, allowing us, then, to respect not only the
holistic nature, but vitalistic nature of these modalities.
DR. GORDON: Thank you very much.
Russell Phillips.
Presenter: Russell
Phillips, M.D.
DR. PHILLIPS: First, thank you for the
opportunity to speak this morning to the Commission.
I serve as Director of the Harvard General
Medicine in Harvard Complementary and Alternative Medicine Fellowship
Program. I am a general internist, teacher, and researcher. To date,
most of my research is focused on end-of-life care, but over the last few years,
it is increasingly focused on complementary and alternative medicine.
I would like to respond directly to each of
the questions that were raised for our panel. First, what training do
conventional investigators need to conduct CAM research?
Investigators need to be well-versed in
research methodology, usually requiring advanced training at a master's or
doctoral level. Investigators need an understanding of CAM modalities they
wish to study, including the paradigms of health and healing held by CAM
practitioners, mechanisms of action where those are understood, and knowledge of
previous research on the CAM modality of interest.
Investigators need mentoring, both by CAM
practitioners and experienced clinical investigators to assist in developing
research questions, methods, analytic plans in preparation of reports for
publication. Ideally, investigators need direct experience in CAM clinical
work, or close collaboration with CAM practitioners. Research training
programs should provide training and research skills, as well as clinical
complementary and alternative medicine opportunities.
At Harvard Medical School, we have a
training program for internal medicine physicians to develop skills needed to
perform CAM research. This program provides master's level training and
research methods, introduction to CAM modalities and practitioners, and
mentoring, both by CAM practitioners and experience clinical investigators.
I would like to describe our program
briefly. The Faculty Development and Fellowship Program in Complementary
and alternative Medicine accepts applicants for a three-year fellowship program
in both general internal medicine and complementary and alternative medicine.
The program offers each fellow an
appointment at Harvard Medical School hospitals. All fellows participate
in an intensive in clinical effectiveness at the Harvard School of Public
Health. Fellow qualifying for acceptance at the Harvard School of Public
Health then pursue a rigorous curriculum that could lead to a Master of Science
or Master of Public Health degree.
The program also includes structured
experiences to improve teaching skills and supervised clinical activities under
the direction of experienced faculty in both general medicine and complementary
and alternative medicine.
Each fellow is expected to design, conduct,
present, and publish one or more investigate projects. This fellowship is
funded by the NIH National Center for Complementary and Alternative Medicine as
a T-32 training program, or institutional NRSA, as described earlier by Dr.
Pearson.
Our program begins each July 1st, with a
seven-week summer core curriculum taught by program faculty and collaboration
faculty at the Harvard School of Public Health. This is what is known as a
Clinical Effectiveness Program. This curriculum includes required courses
in biostatistics, epidemiology, and elective courses in health policy, health
services research, decision sciences, quality improvement, and public health
ethics.
The intensive summer experience includes
about six hours per day of classroom time, and about four hours per night of
assignments, including required class presentations and development of mini
grant proposals.
After completion of the summer core
curriculum, fellows accepted in the Master's Program may then continue to take
advanced courses at the Harvard School of Public Health, and upon earning 40
academic credits, obtain a Master of Science or a Master of Public Health
degree.
Although the degree itself is optional,
fellows are strongly encouraged to take specific advanced course work that will
develop the investigative skills required for the regional research projects.
Fellows also attend weekly seminars or
research conferences addressing research in progress and study design.
These sessions, which bring together fellows located at various sites within the
program, reinforce skills learned in the classroom.
Monthly seminars in the Center for
Alternative Medicine Research and Education at Beth Israel Deaconess Medical
Center provide a forum to present and discuss ongoing research, and a journal
club provide opportunities to review recently published research.
Beginning at the end of the summer core
curriculum of the first fellowship year, each fellow provides care for
patients. Fellows also work with alternative providers, observing their
practices. In integrative practice site at Beth Israel Deaconess Medical
Center is under development and will likely serve as a clinical site for our
fellows in the future.
Each fellow participates in a series of
teaching how to teach seminars under the direction of clinicians who are
recognized as outstanding teachers. In addition, each fellow has
opportunities to serve as a teacher of medical students and house staff in the
ambulatory practice of their sponsoring clinical site, and also to teach
undergraduate courses and continuing medical education courses in alternative
medicine at Harvard Medical School.
Each fellow works in close collaboration
with a faculty mentor and initiates a research project during the first year of
the fellowship. The project may use any or all of the methodologic
disciplines that are included in the academic curriculum and focus on
complementary and alternative medicine.
Projects may utilize a variety of
methodologies and topics that include clinical epidemiology, clinical trials,
decision analysis, patient outcomes, health services research, health policy, et
cetera. Fellows present their plans in research in progress at seminars
within the program, and are encouraged and expected to present their findings at
regional and national meetings of investigators, such as the upcoming
International Scientific Meeting on Complementary and Alternative Medicine to be
held later this week in San Francisco.
They will also be invited to present their
work at the Annual Continuing Medical Education courses directed by the Center
for Alternative Medicine Research and Education at Beth Israel Deaconess Medical
Center.
Faculty in the program are recognized
leaders in general internal medicine, and also include experience CAM
researchers and practitioners. I have listed a number of those faculty in
the materials that you have. These include Joseph Audette [ph], who
studies acupuncture; Edward Chapman, homeopathy; and David Eisenberg, who is
interested generally in CAM research.
I direct the program, and Dr. Eisenberg,
Director of our Center for Alternative Medicine Research and Education, serves
as co-director. Our program is particularly interested in applications
from individuals from underrepresented minority groups.
The reason I describe our program in such
detail, is I think it emphasizes the aspects of training that I think should be
incorporated into training for clinical investigators in complementary and
alternative medicine.
The next question was, are there specific
issues involved in training conventional researchers to study CAM questions?
Conventional researchers need to understand
the CAM practice being evaluated, and need to work collaboratively with
CAM practitioners who are
expert in the CAM modality being studied. Several research issues are
potentially problematic. These include consideration of the placebo
effect, difficulties in blinding both patients and investigators, and
difficulties standardizing interventions.
I agree with the previous speaker, though,
who said that these are issues that we face in evaluating conventional medicine
as well, so are not necessarily new or different.
The next question is, what training do CAM
professionals need to collect valid data, collaborate on research projects,
contribute as members of research teams, and design and conduct high-quality
research?
These research activities are obviously
listed in order of increasing complexity. For each of these activities,
the necessary training would be similar to that required of other clinicians who
participate in research.
Commonly, clinicians are trained in
relatively short training sessions to collect and record data. Member of
our own research group did this successfully in an NCCAM-funded study of
patients seen by chiropractors, acupuncturists, naturopaths, and massage
therapists. Training sessions should include the fundamentals of research
methods, how to collect and store scientific data, and human subject protections
that need to be in place before research can be performed.
For CAM providers to collaborate and
contribute as members of a research team, they need increasing research
sophistication, which may vary depending on the study under consideration.
In order to design and conduct high-quality research, CAM providers need the
same training we provide to our physician-researchers, as I described earlier.
The next question is, how can CAM
practitioners become better educated in the critical evaluation of CAM product
claims and the results of CAM protocols in clinical research?
Similar to the training physicians should
receive, CAM practitioners need training and skills necessary to critically
appraise a published study. These skills include a basic understanding of
research design, and the limits of each approach, an understanding of different
measures of effect, of the meaning of p-values, statistical significant,
confidence intervals, and potential sources of bias and confounding.
An excellent series of papers on critical
appraisal skills has been published in JAMA, which form the basis, for many
critical appraisal courses taught to physicians, and could easily be adapted for
CAM practitioners. Ideally, these courses on critical appraisal skills
should be taught as part of the undergraduate program or clinical training
program for CAM practitioners.
Given the limited regulation of CAM product
claims, it is especially important for CAM providers to be able to assess the
strength of evidence supporting these claims.
The last question was, what policy
recommendations could I offer. First, I agree with the speakers who
recommended that there be increased funding for CAM research and that this be
made available for training programs for both conventional investigators and CAM
investigators and practitioners.
We need increased funding for career
development awards to enable investigators focusing on CAM to develop into
independent investigators, and we need increased funding for mid-career
investigator awards to provide support for the time required to mentor new
investigators. Thank you very much.
DR. GORDON: Thank you very much.
Richard Hammerschlag.
Presenter: Richard Hammerschlag, Ph.D.
I am fortunate to have had two careers in
research, one spanning 25 years at the biomedical lab bench, and the other now
reaching 10 years involved in challenges of exploring acupuncture and CAM.
At present, I am the Research Director at
the Oregon College of Oriental Medicine. I am involved in clinical
research trials at the two NCCAM-funded centers in Portland, and I serve as
Co-President at the Society for Acupuncture Research.
From my dual perspectives of biomedical and
CAM research, it is a pleasure to offer input for the strategies you are
developing to help sail the ship of CAM on the seas of evidence-based
medicine. I would like to address three concerns.
First, the need for CAM research to more
clearly reflect CAM practice.
Second, the need for better training of both
CAM and conventional practitioners in the skills necessary to evaluate the
quality of CAM research articles.
Third, the need to examine, systematically,
what CAM practice and research are revealing about how the body works that
biomedicine has not yet figured out.
First, I will address why I feel that much
of CAM research has been inadequate in its evaluation of CAM practice. The
need for CAM research is reflected in the creation, first, of OAM, and its
upgrade to NCCAM, has been recognized because of the widespread public use of a
wide range of under-researched CAM therapies.
It follows that what needs to be evaluated
in clinical trials is how people are being treated. In contrast, what too
often appears in clinical trials is a CAM therapy morphed into an
allopathic-like treatment, resulting in standardized protocols and variably
designed, non-validated placebo treatments. The challenge for CAM research
is to maintain rigorous research standards, while having the protocols reflect
the real-world practice of the CAM therapies.
When a CAM practitioners reads a research
study, I often think, their response should not be, this protocol is far too
restrictive or simplified; I would never treat a patient that way. Rather,
their response should be, well, I might not treat my patient in exactly that
way, but the protocol is reasonable, given the presenting condition and
diagnosis.
Well, my years in biomedical research have
left me with an appreciation of the need for controlled trials. I believe,
given the limited resources available for funding CAM research, that undue
emphasis is placed on placebo-controlled trials.
What I see a greater need for are what
researchers call "trials of pragmatic efficacy," in which two treatments are
compared under conditions in which they would applied in practice. To
quote Kapchuk, Edwards and Eisenberg, "A pragmatic perspective provides less
scientifically useful information, but potentially provides more clinically
relevant information."
As one example, a patient with tennis elbow,
and also the patient's practitioners, in this case, an acupuncturist, are less
interested in a clinical trial that has demonstrated acupuncture to be more
effective acupuncture, than in an equally rigorous trial in which acupuncture
was found to be as effective as steroid injection, and with fewer adverse
effects.
So my recommendations here are, first, that
NCCAM be encouraged to call for research proposals that clearly reflect
real-world practice of CAM.
Second, that CAM research proposals
submitted to NCCAM and to the various NIH institutes, be required to have had
CAM practitioners involved in the research design.
Third, that the CAM research design in such
proposals must be accompanied by a clear rationale, and must have been approved
by a consensus panel of experienced CAM practitioners.
Fourth, that representatives from the
NCCAM-funded centers should meet periodically, not only to present progress
reports on their research, as they currently do, but to exchange experiences of
how best to educated researchers in CAM practices, and how best to introduce CAM
practitioners to the research culture.
I will be briefer in presenting the second
and third of my three general concerns. My second concern stems from
teaching and lecturing about CAM research in general, and acupuncture research
in particular, to students and practitioners of CAM, as well as conventional
medicine.
What I repeatedly encounter in this era of
evidence-based medicine is a serious need for training and for continuing
education in how to understand and evaluate CAM clinical trials. Most
practitioners, CAM and conventional alike, are neither well trained in the
general principles of research design, nor appreciate the difficulties inherent
in applying conventional clinical research methods to CAM research.
Yet, increasingly in their clinics,
CAM and conventional practitioners are facing, or at least
should be facing, the task of reading and evaluating CAM research. Too
often, there is more attention paid to whether a trial's outcome is positive or
negative, rather than to whether the trial was designed well enough to have
provided an adequate test of the CAM therapy.
My recommendations here are, first, that
students at allopathic medical schools, as well as CAM colleges must be taught
how to understand and critique CAM research trials. I echo Dr. Phillips
here.
It is necessary, but not sufficient, to
offer survey courses of CAM practices, as an increasing number of allopathic
medical schools have been doing. There must also be survey courses in CAM
research.
Second, the CAM and conventional medical
practitioners should be encouraged, if not required, to take continuing
education seminars in how to understand and critique CAM research trials.
My first two concerns focused on the
question, does CAM work. My final concern addresses the question, how does
CAM work. With all the current emphasis on clinical trials, we are not
paying enough attention to a profoundly interesting parallel development of CAM
practice in research, that CAM is revealing ways in which the body works that
biomedicine has not yet figured out.
As we set off in these new directions, three
things need to be explored, the psychophysiological basis of the placebo
response, the physiology underlying Reiki, qigong, therapeutic touch, and other
CAM practices that are defining the landscape and boundaries of energy medicine,
and third, the basis of healing practices, including distant healing and
intercessory prayer, that unlike the phenomena underlying energy practices,
appear to be non-mediated, as well as non-local.
Notable for its virtual absence from the
recent NIH conference on the placebo was any studies on the physiology of the
placebo effects. While such effects are certainly not solely within the
province of CAM, biomedicine appears little interested.
Yet, an understanding of the essential
feature of the placebo response, what I call the "transformation of meaning into
molecules," will surely provide us with major insights into a range of mind-body
CAM phenomena, as well as improve the non-specific effects of healing. As
Harris Dienstrey [ph] elegantly understates, "The mind as a source of medicine
is waiting to be explored."
Second, while the term "energy medicine" is
often used today in an amorphous manner, research on bioelectric magnetic fields
produced by every organ and tissue of the body, and detected at the palms of
quigong masters, is giving form and substance this term of "energy medicine".
Even at the molecular, what I learned as a
graduate student in biochemistry is undergoing a sea change, in which
biochemistry is being considered, largely, as a solid state phenomena.
Briefly, in this view, signaling occurring
within and between cells and tissues occurs alongside the skeletal structures,
along proteins that span the cell membranes, and along the extracellular
matrix. The fixed ionic charges at the surface of these structures allow
electromagnetic signaling at orders of magnitude faster than signals mediated by
diffusible biochemicals.
Lastly, we must expand our understanding of
the human body by scientific study of healing phenomena that do not appear
explicable in terms of either molecular medicine or energy medicine. The
marked lessening of symptoms in HIV-positive patients and the physiological
improvement of patients in coronary care units are recent examples of elegantly
designed, randomized, controlled trials, assessing a therapeutic practice
involving mental intention by healers at sites remote from patients.
How is such healing received by patients,
and how does it alter physiology? Answers to such questions are of
profound importance for redefining our concepts of self and for the reshaping of
future health care.
Finally, my recommendations here are two:
that medical school survey courses of CAM and integrative medicine should
include research findings and emerging concepts that challenge the prevailing
views of physiology and pathophysiology.
Second, that NCCAM, or perhaps even the
National Academy of Sciences, should be encouraged to call for a conference that
would propose evidence-based models for expanding our present concepts of
physiology, and that would recommend an agenda for future research. Thank
you.
Panel Discussion
DR. GORDON: Thank you, and thank you
for those very thoughtful and stimulating suggestions. Thank you all.
I have a general question that I would like
to ask Nancy Pearson and Neal West.
What has been the response to the training
of researcher's program, and what are the challenges or obstacles, and where
would you like to see things go with the program?
DR. PEARSON: If you are talking about
the response from institutions who are applying, I think the numbers are
increasing, and we hope to increase the number of training grants that we offer.
DR. GORDON: How many people have
applied this last year, or how many institutions?
DR. PEARSON: I don't have an exact
number on that. I could certainly get that information to you in a written
statement.
DR. GORDON: But it has been increasing
each year.
DR. PEARSON: It has been increasing
each year, yes. You can see that in the amount of funding that has
increased from 1.3 percent up to about 3.8 percent in 2000, and it continues to
increase.
DR. GORDON: So the funding is not
preset.
DR. PEARSON: No, not at this point.
DR. GORDON: Maybe you could explain to
the Commission a little bit about how that works.
DR. PEARSON: My understanding from our
director is that we will continue to increase up to a certain level. If
you look at all of NIH, the funding for training NRSA and career development
awards ranges from about 2 percent up to 11 percent. So at this point,
since we are just starting out, we are closer to the bottom end, but we are
still increasing our funding, at this point.
DR. GORDON: What do you see as the
challenges in getting more institutions and more individuals interested in these
particular grants?
DR. PEARSON: I think, just getting the
word out that we are interested. We are revising our website right now to
give a lot more information about this, putting information about our presently
funded centers and institutional training grants on the website as possible
places where people can be trained. So any way we can get out more
information.
DR. GORDON: The other question
related, is, I noticed in the testimony you said some of the NCCAM centers
presently have research training, which implies that some don't.
Does that mean that is not required for the
NCCAM centers?
DR. WEST: The first iteration of the
NCCAM center announcements did not require set-aside money for training and
career development, although we appreciated that it would occur in the research,
in the process of doing research.
What we have done, as the center program has
been reannounced, is that we have not only included training and career
development as a specific item that is adjudicated in peer review, we have
suggested guidelines for a set-aside of a portion of the total award and
requested that it be committed to training and career development, and we, of
course, track that in several ways.
Following up on one of the things Nancy said
about our increased visibility in terms of the various ways in which we can
participate in training/career development, one of the things that has occurred
in the last year is that every time the NIH, through the guide process, has
announced a new training and career development initiative, and again, a lot of
these are done in a trans-NIH way, we have signed on.
Our name is on the top. It is very
visible. We have got a contact person, because there are a large number of
these. Our director has insisted that we sign on the full range. A
lot of NIH institutes and centers tend to support only a narrow range of
training and career development grant mechanisms.
We are signing, given the diversity of our
community -- and you will note that in those announcements, the CAM practitioner
community is specifically identified, by degree, as folks who are invited to
participate in that mechanism, rather than it being understood in the other
related language that often occurs at the end of those announcements.
In addition, I have written as a separate
pre-doctoral fellowship announcement and Dr. Pearson has recently published a
post-doctoral fellowship announcement, both specialized in complementary and
alternative medicine.
DR. GORDON: Thank you very much.
DR. HAMMERSCHLAG: Could I just add a
quick perspective? Christine Gertz from NCCAM recently told us some very
interesting statistics, that they have been tracking how many proposals they
have received from CAM colleges, and the number is 26, if I am remembering
right. Only one CAM college, which is Bastyr, has ever been funded, and
they have submitted, maybe, 11 or 12 out of those 26.
This speaks to a real need to improve the
research infrastructure and training at the CAM colleges to get that
perspective.
DR. GORDON: Hasn't there been a
chiropractic college?
DR. HAMMERSCHLAG: No. There is a
chiropractic center, which is a consortium, one of the currently funded NCCAM
sites.
DR. GORDON: I see. So your point
is that --
DR. HAMMERSCHLAG: Talking about
individual grants, that this is what NCCAM has been tracking.
DR. GORDON: Do you have any more
thoughts about that?
DR. HAMMERSCHLAG: Yes, that there
needs to be -- I am most familiar with the acupuncture colleges, and there are
very few people like myself, with a research background, in the acupuncture
colleges. So their ability to even develop the research infrastructure is
limited. They don't understand what is needed. A training program
that would be directed at the CAM colleges would be extremely valuable.
DR. PHILLIPS: Could I just add one
other thing? As someone outside NCCAM, I should say that these training
grants are incredibly important to the development of investigators who focus on
CAM. The general way our careers develop is that, generally, we will spend
a focused amount of time as a fellow to do research, and then that allows us to
create the track record and focus that we can then use to apply for our career
development awards, which would be the K-08 or K-23 award.
So the centerpiece really needs to be the
individual NRSA, or the institutional NRSA, which provides a fellowship
training, from which you can then progress to a K award, which will allow you to
develop into the type of independent investigator that they can successfully win
R-01 grant support.
One other comment is that we are
interviewing now for our third group of applicants. We actually applied
for this award, the T-32 Training Grant, because we had a large number of
fellows coming to us, or applicants coming to us, with specific interest in
complementary and alternative medicine.
Since we have started publicizing this
program, the numbers have grown fairly dramatically. The last year, we had
three or four applicants. This year, we are about 15 or 16, which is
almost as many as general medicine applicants, as we get to our fellowship
program that has now been in existence for over 20 years.
DR. GORDON: Thank you very much.
I have Charlotte, Linnea, and Tieraona, and Effie, Wayne.
SISTER KERR: I am feeling just a
little bit sad this morning, and it is not because of your excellent
presentations or your dedication. I think I am speaking to the whole
morning when I speak, and predominantly as a practitioner right now.
Yesterday, I spoke of a patient I saw
recently, and I want to say something about that. This person presented
with pain in the back of her leg, about a 33-year old lady. In doing the
history, many labels came up from a biomedical model, for example, Reynaud's,
dysmenorrhea, allergic rhinitis, headache with her period, brittle hair, some
mild anxiety, not considered a clinical problem, craving salt, she had lost her
friends because she couldn't run, and chronic constipation since a little girl.
Now, it often might be possible that almost
all of those symptoms would go away, but her leg would still hurt. This is
not unusual, as we practice in traditional acupuncture. What I want to say
is, in traditional acupuncture, and in other CAM therapies, we often -- I, we --
want to study whole energetic systems. It is based on an energetic
physiology. We don't focus on one symptom change as a desired outcome.
Now, these new understandings of new
physiology changes, in my opinion, future agenda methodologies, and Richard, you
spoke to this. I don't see this happening. Now, you need to know I
have been in this process for several months, and so, this is not like just
today I thought of that.
I am listening to some of the most
dedicated, fine minds in this country, over many weeks. I had a small part
in planning the NIH Consensus Conference on Acupuncture, and I understand the
impact that had on this country and the world. As an acupuncturist, I am
delighted that we know it helps dental pain and post-operative nausea, but it
was, in the South Carolina language, podunk outcomes, as far as I am concerned,
as far as what is possible.
I am not discouraged because I don't see any
of this thinking, but I don't see enough investment in acknowledging there is a
new aspect of physiology. I understand it is not in the West world's
established view of physiology yet, formally anyway, but I don't see the
desire. In these wonderful training programs, where is it built in to do
the epistomological reflection, the new world view reflection?
So this is my general question to you, are
we moving there any faster? It gets a little bit back to Ming's point this
morning, that we can have an outcome that something doesn't work, simply because
we are not studying the way we work. Thank you.
DR. BLANKS: Could I have the
opportunity to respond to that, please? I happen to agree with you 100
percent, and you might remember, I was trying to paraphrase my comments, not so
much evidence-based, but more people-based, holistic-, vitalistic-based.
Indeed, I would hope that we are moving in
that direction so that we can begin to see, not only the person as a total, but
also how they related to their social networks, how they relate to their
environment and their social structure.
I think there is a strong movement
there. With the incoming medical students, with my younger colleagues, I
see a very strong sense of, I am burned out on the managed care system; I have
to spend more time worrying about the details of treating patients as patients,
and not just an endless list of symptoms.
I don't know that this being addressed well
enough at the NIH level, largely because it is hypothesis-driven and it is very
difficult to center a hypothesis around quality of life as the single outcome
measure.
But we do see this. We see it,
certainly, in our cancer protocols. At our university, the physician who
is chair of the IRB will have $50 million worth of hypotheses or drug treatment
protocols, and almost every one of them now has a quality-of-life
component. So that part is beginning to drift in here.
I would applaud that perspective, and I am
going to hold my banner up and say, I am there but I am also on the other side,
too. I am hoping that we can go in this direction very strongly.
DR. HAMMERSCHLAG: I will have a go at
the other part of your question about, there is a real need to develop an energy
physiology to start to become the base for, and not just an energy physiology or
a beyond-energy physiology, but, how do we do this.
There are two general approaches to try to
get at some structure to this. Ann Harrington at the Placebo Conference
spoke elegantly about what she calls "sightings". We don't know what the
phenomena is, but whatever it is, this and this and this phenomena, have to be
explained by it.
I will just give you one example.
There was a study in Japan where a new chemotherapy protocol was being
tested. Forty percent of the patients in the placebo group experienced
significant hair loss. This is not just heart palpitations or slight
dizziness, this is a major biomedical symptom. What is going on here; we
don't have a clue about this.
Fabrizzio Benedetti was the closest that
anybody talked about physiology of placebo at the Placebo Conference, but he
spoke eloquently. He drew on the board a box. He said, I want you to
know the placebo, what we need to know is in that black box, and what I found,
the endorphins, those are outside of the box. We need to know what the
transduction, we call it in biomedical terms, how does that meaning get
transduced.
So sightings are one way. The other
way that Beverly Rubik goes about it, is she talks about an agenda where she
looks at parallels. She asks, what are the parallels with biomedicine that
we need to establish; are there specific receptors for bioelectromagnetic
fields; what are the pathways in the body by which we can get instant signaling
between different parts of the body to look at the parallels between existing
physiology.
So those are two approaches that I can begin
to see, but there is enough out there to begin to bring the mind-body people
together with people. When we say biomedicine isn't aware of this, it is
not true. We have been doing EEG and EKG and electroretinogram.
It is the same kind of bioelectromagnetic
fields that are produced at much lower levels by all the tissues in the body,
and this is surely our window into the future way of diagnosis of subclinical
imbalances that need to be corrected before they become, in Western science,
symptoms.
SISTER KERR: I just want to say, as a
policy recommendation, we are going to say a lot about more research. I
would like to know some language so that we can say, how can we be more
specific, because we are going to get the same biomedical research, I think.
DR. GORDON: Linnea.
MS. LARSON: Thank you all for your
very wise and useful observations. I could ask this question of all of
you, but I am going to limit it to Dr. West and Dr. Pearson.
Of the fellowships that you have offered,
how many of your candidates come from the worlds of medical anthropology,
masters of divinity, law, social services, family therapy, those areas that are
considered quite soft?
DR. WEST: I was Nancy Pearson before
she joined NCCAM. I was the fellowship coordinator for NCCAM, even though
she has as many years of experience and fellowships. I was happy to be the
program officer during the time we did have applications, pre-doctoral fellows,
in areas such as you are describing, in studying shamanics, for instance.
Two of our F-31 fellows, these are
pre-doctoral fellows who are actually doing research very similar to what you
are describing. One of the beauties of the pre-doctoral fellowship program
is to allow field studies off-site for many months. Those individuals took
advantage of that. We have been very receptive to medical anthropology as
an area for support.
MS. LARSON: Medical anthropology, can
you expand that to include, let's say, M.D.V.s, law, historians of science?
DR. WEST: Yes. Those are just
areas that, frankly, we haven't had applications in. One of the points,
and I tried to address it by describing, for instance, our K awards in all the
different categories, is that, I am sure those of you who go to the NIH to
grants and contracts, you see that this is an incredible variety and labyrinth
of different grant mechanisms, which tends to be way we are able to support
people, through peer review.
So we fall back on those mechanisms.
There are grant mechanisms that exist, including what we have and some others
that can accommodate almost any biomedical approach need. Some of the ones
you are describing, in my mind, I immediately think of grant mechanism and
hypothetical applications, but those are not the kinds of things that we have
gotten in yet.
Again, one of the points I was trying to
make about our increased visibility and our signing on to existing announcements
and developing our own, is that, when we do this, people appear. They
don't just appear, we work with them to put together applications.
Let me just say that training and career
development have very generous success rates across NIH. Our director is
very aware of this. NIH publishes success rates, and the success rates,
which are our chances of getting money, are significantly higher in our
fellowships and in our career development awards compared to research grants.
That is true across NIH, and it is certainly
true in our center. It really has to do with the applicant community
finding us and coming to us. We have been going out. I went to the
last two meetings of the American Association in Naturopathic Physicians, and I
felt like the pied piper of Hammelin. People are very, very
interested. They come to us, and they start thinking about it and talking
about it.
Sure, there is a lag period. People
need to finish their chiropractic training, but the interest is out there, and
we are in a position to respond.
DR. PEARSON: If I could just make one
additional comment, which really reflects what Neal says. We are really
just gearing up, because we only started funding in 1999.
I have just been with the organization for
two months, but during the time I have been there, I have gotten many, many
calls from people who do manage to find us, either through our website or
through other publications. I have gotten calls from spiritualists, people
interested in hearing. I will admit I have not gotten any calls from
people who were in law, but that could happen.
One of our roles is really trying to
introduce them to the NIH system, because it is very complicated for people
outside the system. So a big part of our job is spending a lot of time on
the phone, coaching people, telling them how to apply for NIH grants. We
do get individuals from a wide variety of different disciplines and professions
calling us. I am sure that will expand as we become better known.
DR. GORDON: Thank you.
Tieraona.
DR. LOW DOG: I am not quite sure how
to ask this and make it come out sounding the way I want it to sound. I
have heard we need to be studied in the way we really work, or the way we really
practice, that we need to relate to the total person, that this whole,
vitalistic approach needs to be studied.
I guess I am sitting here as a somebody who
went to a medical school and a rural family practice program where
cross-cultural medicine was taught, psychosocial impact on health, a month at
the wellness center for smoking cessation, exercise, weight management,
perspectives in medicine every two weeks for ethics and social approaches to
health, and I am curious, because when you are studying antihypertensive, you
are not studying the way we practice, either.
You are not studying the way family doctors
practice in our office. You just don't come in, we take blood pressure,
and we give you a pill. I mean, I hope not. That is not the way most
of us practice. We know who you are, and we know your issues, and we talk
to you about stress, and we talk to you about what is going on, we talk to you
about your diet and what you are doing, and exercise. We do all of those
things.
I am concerned, on some level, that in some
way we are saying that there is a different relationship that occurs in
complementary and alternative medicine between the healer and the patient than
what can occur, and often, I do believe, does occur in many, many physicians'
offices, especially primary care and rural, where I have seen just tremendous
amounts of this, and that, if we are going to do it for one, why wouldn't we do
it for the other; and why aren't you interested in studying rural family
practice docs in their real-life practice.
The reason, I understand, we don't do that,
or, my understanding is, because we want to remove the healer from the equation
so we actually know what is working. And yet, all of us who are not
researchers, who are just doctors in the field, believe strongly in our
relationship with our patient.
There is a concern that I have, that somehow
we are separating these out as it is unique to a particular modality, and that
it is not actually across the board, that most dedicated healers have this
common belief and experience.
Any comments?
DR. HAMMERSCHLAG: You are the White
House Commission on Complementary and Alternative Medicine, not a general
commission on health care practices, or health care research. I do firmly
believe that a large amount of our research dollars should be studying health
care as it is practiced in the community.
I would offer you models of the National
Health Service in Britain. They are currently funding two very large-scale
trials of acupuncture compared to usual care. In each arm, as the
practitioner is free to treat as they would treat in clinical
practice.
The National Health Service is
interested. These were competitive grants that they put out. One of
them that got funded is in migraine, the other is low-back pain. They are
exciting not only for the scope of what they are doing, but for the model within
which they are testing these studies. In this case, both conventional and
Chinese medicine practices are being given full scope to treat, and they want to
see how they do.
In this model, of course, you can also test
relative cost effectiveness, relative onset, comparative side effects, and how
long each treatment effect lasts. So that is a very powerful research
approach for asking very different kinds of questions than is, the treatment,
does it have efficacy, which strictly means, is it better than placebo.
DR. PHILLIPS: I think your question
emphasizes the fact that there are parallels between studies that we would do in
conventional medicine and complementary and alternative medicine. The
issue are very similar. The study that you talk about, potentially, is an
important one.
There is a large body of data that looks,
for instance, at whether subspecialists provide different care than
specialists. There are studies that look at care provided by different
types of practitioners, and there are differences. There are studies that
show that female physicians do things differently than male physicians, and
excel in some areas more than male physicians do.
I don't think we necessarily understand why
all those observations exist, but I think it is an important area of study, both
for conventional researchers studying conventional medicine, like family
practice or general internal medicine, or for researchers who are interested in
looking at CAM practitioners.
DR. LOW DOG: Yes, but my feeling is
that there is some sort of common denominator, that there may be common
denominators that are unique to all of us that are not CAM or conventional, and
that if we are completely looking at them separate and in isolation from one
another, we may miss what we have in common by simply focusing on what we do
different. That was my only comment.
This is the White Commission on
Complementary and Alternative Medicine, but it doesn't exist in isolation.
It exists within the system that we are all working within.
DR. GORDON: Effie.
DR. CHOW: Thank you all. I am
not as sad as Charlotte is. I am actually enlightened with some comments
here, relating to the human aspect and the outside-of-the-square comments.
One of our concerns is that the multifaceted
approach with which CAM -- and as I said before, I don't really like that term
-- multifaceted approach to the individual, worrying about it becoming
reductionistic by the process that we are putting it through, and the discussion
about research and how it is researched.
There are two questions here, or comments,
and I would like the comments from you folks. How do we keep it
multifaceted? Because acupuncture, using that as an example, has been
reduced to -- and maybe it will be expanded later on -- to six usages.
Whereas, it is a system of practice in China, and it deals with the whole, human
health and ailings. So that has been reduced.
Also, the utilization of researchers.
What are the qualities of the researchers? Is it acupuncturists and other
practitioners that have had a 200-hour training, and because of their
qualifications in Western medicine, that that qualifies them? Or, is it
acupuncturists who have had 2,000 hours of training or more, and deal with the
whole concept of the laws of the five elements and the relationship of the human
being to nature, all the classical, theoretical concept with the energetics
concept? The results will be different utilizing different types of
practitioners.
That is a comment, but it is a real serious
consideration, and I would love some comments from you folks. What are
some of the qualifications, for example, at Harvard, that you are utilizing for
acupuncturists? And comment on other practitioners, too, and for the
others, as well.
DR. PHILLIPS: I can't speak to the
exact credentials that are required. It varies, depending on the different
study, but I guess there are two principles that a number of our studies
follow. One is an individual study trying define a scope of practice that
represents what practitioners would do in the community for a specific problem.
So we are trying to avoid the problem of
providing such a narrow and prespecified intervention that bears no relation to
what a practitioner is really doing, and we try to develop that scope of
practice, working with, in the case of acupuncture, groups of acupuncturists who
agree that certain treatments are reasonable treatments for a specific
condition.
We also, for all of our alternative
practitioners that we are involving in research studies, have a lengthy
credentialing process to ensure that all the practitioners have had a certain
level of training and number of hours training and practicing. I don't
know, off hand, exactly what that requirement is.
DR. BLANKS: I would also like to
address your comments there. I, too, am very concerned about what are
holistic disciplines, complete health delivery systems. Oriental medicine,
I believe, is one, and I have some familiarity there. Subluxation-based
chiropractic, in many respects, fits this entire health delivery system concept;
take care of the patient, and they will take care of themselves. There is
a vitalistic component there, an innate intelligence, if you will, if take care
of that aspect.
I am concerned, and I tried to convey some
ideas about several different model approaches. Hopefully, you don't
settle on one, that you should settle on several, which I believe would allow
the ability to deal with entire disciplines, not taking in parts of those
disciplines to treat specific symptoms.
To come back to the commonality here.
If indeed we are treating patients, patient health and their wellness in the
illness-wellness model, than we would have done due diligence in terms of our
health outcome measures, our research documentation base, and so forth.
I will go back to her comment as well, and
that is, at our university, the only person allowed to deliver acupuncture in a
clinical setting is not a person trained as a doctor of Oriental medicine, where
they have --
DR. GORDON: Excuse me, I am going to
interrupt. We are already over time. If you could focus on research
training aspects in response to the question, okay?
DR. BLANKS: Very quickly, then, I
guess the point is that we have done this reductionism so much now that the only
person who can deliver the acupuncture in that setting, in primary health
delivery, is the physician. I think this is a problem that begins with the
training very early on, to realize that there is an entire body of evidence that
one has to learn in delivering health in these other disciplines.
DR. HAMMERSCHLAG: Can I briefly just
say one thing? I want to point out what Alex White mentioned in the early
panel, that when the NCCAM centers are funded, there is money for training CAM
practitioners, but just as it is with mainstream training grants, these are
post-doctoral awards.
The Kaiser Center realized that if they were
going to be post-doctoral, they could train chiropractors and naturopaths, but
they could not bring in acupuncturists or massage therapists, so they called
NCCAM and got them to allow them to create half-time fellowships that were open
to any CAM practitioner who had achieved the highest level of training in their
profession. So, another obvious mechanism for training.
DR. GORDON: That is very helpful.
Wayne, this is the last question, and then
we will take a break.
DR. JONAS: Dr. Blanks, outside of
NIMH, which I think has made an effort to begin to have a dialogue about the
synthesis of these different evidence approaches that social science and the
biomedical model have taken, are there any things outside of the CAM world and
the conventional research that are beginning to bridge these areas, that you
know of?
DR. BLANKS: Actually, there are some
other disciplines. The National Eye Institute, for example, has an
approach that would be health outcomes-based, broad health measures. It is
something that I am seeing drifting into the literature very quickly.
There was a recent RFA that would have addressed the specific issue, and many of
the others, I am not aware of.
DR. JONAS: I know, as more energy
builds for another methodology conference in this area, and I think Dr. White is
in the process of helping with others, this might be a thing to consider, one of
those aspects.
I wanted to ask Neal and Nancy -- first of
all, I wanted to congratulate you on the wide array of participation in the
training grants that you have rapidly moved into in getting NCCAM
involved. I think it is heroic. Knowing the work that it takes to do
that, it is just an incredible feat.
I am wondering if one of the next steps is
to try to see if it can't be stimulated a little bit more through an RFA
process, specifically setting aside some money targeting that. When that
happens, as you know, you get a lot of people that come out of the
woodwork. There are a lot of things, that even if they don't get funded,
begin to develop.
There has been one on curriculum
development, but it wasn't focused specifically on research training, and I was
wondering, is there any thought or discussion of doing some specifically on
research training to help supplement this?
DR. PEARSON: I will just mention one
thing. There is an RFA out now on institutional training grants for
minority research, and that is getting some response. To my knowledge,
there is not a specific plan for another one in the future, although Neal might
want to talk about curriculum.
DR. WEST: As you know, there is a
curriculum development announcement with set-aside money that is an ongoing
activity that provides CAM clinical trial curriculum support. That is an
ongoing announcement, which has one more year left on it with set-aside money.
One thing I would like to address about our
training and career development, I know we have presented you with a bit of what
I call an alphanumeric soup of different Ks and Fs and Ts, but there are really
a couple of threads, and one very specific thread, that runs through all of our
training and career development, and that is that these all require an
interdisciplinary, integrated research training environment that includes both
CAM and conventional skills.
We really want to bring those skills
together into our training environment. Whether it is a K, a T, an F, that
is not important. We really have an underlining belief that by bringing
those folks together in that training environment, that what has to develop and
has to be transmitted to the next generation of researchers and practitioners is
this mutual respect for each other's healing approaches, and an appreciation
that there are overlapping paradigms in conventional and complementary and
alternative medicine.
DR. JONAS: I think that is fabulous,
and I think that it would be great if perhaps you could stimulate. There
is such a dearth of good, qualified researchers in this area, as evidenced by
difficulty in sometimes getting good grant applications, that it really needs an
investment.
To do it right, of course, is complicated,
and you ideally need to partner with a number of the other institutes.
Anyway, that would be something I would suggest to you.
DR. GORDON: Thank you. And thank
you, Nancy Pearson and Neal West for your, as Wayne said, heroic work in moving
the field ahead. I want to thank the other three of you for the exemplary
demonstration efforts.
Also, Richard Hammerschlag, if you have that
curriculum for a course in CAM research, we would love to see that. That
would be very helpful to us in our deliberations. So thank you very much.
We are going to take a 15-minute break, and
let me thank, in advance, the editors of the journals for their patience as we
have gone a little bit overtime. We will back in 15 minutes.

Panel VII: Publication of
Peer-Reviewed
CAM Research Results
DR. GORDON: Good morning, all, and
thank you for being here with us. We would like to begin the panel with
Edward Campion, please.
Presenter:
Edward Campion, M.D.
DR. CAMPION: Thank you, and thank you
for the invitation to appear before the Commission.
I am an internist trained in rheumatology
and geriatric medicine. I have appointments at Massachusetts General
Hospital and Harvard Medical School, and for 13 years, I have been a deputy
editor at the New England Journal of Medicine.
The first commitment of a medical scientific
journal is to publish research that is accurate and relevant to the journals'
readers. Hence, the journals must assess both the evidence in a report and
the process by which it was obtained. Peer review is not infallible, but
it does improve the quality of scientific articles and provides editors useful
information as they make decisions about manuscripts.
Some of the questions that editors at
journals ask are, how important is this research question; what exactly is the
question trying to be answered; how rigorously was the work conducted; are the
results reproducible, generalizable; were the data analyzed in a way that is
valid, statistically; does the report recognize other research that has been
done on this topic.
A fundamental obligation of every type of
medicine is to identify what treatments can help patients and describe the basis
of that information in a way that is objective and useful. Researchers
must identify specific questions, and researchers must recognize that their
beliefs and prior impressions may turn out to be mistaken. In any
controversial area, it is useful to gather basic descriptive information about
what current practices, beliefs, and economic consequences, actually are.
Clinical studies must be conducted in ways
that minimize bias, including biases that may come from either skeptics or
enthusiasts, from investigators or patients. Comparison with appropriate
controls can increase confidence and results, as will comparisons with other
treatments.
Research evaluations should try to identify
what degrees of change are clinically meaningful, and recognize that small
differences may not be of any real benefit to patients. Particularly, in
chronic symptomatic conditions, the natural history may include large
variations, independent of any treatment. In all clinical studies, more
complete follow-up increases the strength of the evidence.
We must also recognize that some very
important aspects of medical care are never captured very well by any
research. These include a patient's hopes and expectations, and inner
beliefs, the provider's attitude, and manner toward the patient, the past
histories of both, and the personal relationship between them.
For policy recommendations, I will make
three. First, give priority to investigation of those few types of
unconventional treatment that can cause major harm, especially unregulated use
of drugs, herbal products, and so-called dietary supplements. At our
journal, I should say we see little evidence of reports of rigorous research of
CAM. We have published some reports of major, even life-threatening
toxicities from substances such as astrolochia, PC-Spez, and a dietary
supplement, ephedra.
I believe the FDA should have responsibility
for safety testing of herbal medicines and dietary supplements.
The second recommendation. Encourage
and support objective research studies, but only for modalities with evidence of
genuine promise. Beware of a research trap. Research dollars are
precious. They should not be wasted on trying to define 1,000 ill-defined,
unconventional practices, most of which are harmless.
Finally, there should be more investigation
of the reasons why consumers seek out unconventional therapies. One
reasons may be dissatisfaction with our nation's conventional health care
delivery system. Thank you
DR. GORDON: Thank you very much.
Jackie Wootton.
Presenter: Jackie
Wootton, M.Ed.
I note that three of the Commissioners are
on our editorial board. One is a former member of our editorial
board. Two of the panelists today are on our editorial board, and two of
the panelists today are authors in this latest issue of the journal.
We believe that the review process for the
Journal of Alternative and Complementary Medicine is essentially the same as
that for any major biomedical research journal. I joined the journal in
March 1996, and I am responsible, with the editor-in-chief, Kim Jobst, M.D., for
running the peer-review process.
I was determined from the start to emulate
the high standards of expert and impartial review that are accepted practice for
all quality academic publications. The journal was accepted for indexing
by MEDLINE within its first three years of publication, back-dated to the start
year, and has steadily gained a strong reputation as a serious CAM research
publication.
Ideally, the criteria for accepting articles
is that they are clear and coherent and scholarly, the description of methods
and materials is complete and replicable, that studies are contextualized within
the appropriate existing bodies of knowledge, and that claims and conclusions
are supported by evidence.
When selecting reviewers, I take into
consideration the author's recommendations and requests for excluding certain
reviewers. We have a large editorial board who review and are available
for consultation. I have also built up an extensive database of expert
specialist reviewers for the field.
Review is anonymous, but it is not
double-blinded. That is, the reviewers know who the authors are, but the
authors do not know the identity of the reviewers. There are usually three
reviewers, one with the appropriate CAM knowledge and expertise, one
conventional biomedical researcher, and I am fortunate that my office in
Bethesda is right next door to the NIH, so I have many friends and colleagues,
and I can sort of pop across and say, hey, I need a hepatologist or
whatever. This is a very, very important part of our review process.
Then we also seek a methodologist or a
statistician, and I have to admit that that is actually very difficult to
sustain. I collate the reviews and consult with my colleagues. The
editor-in-chief, Kim Jobst, ratifies the final decisions. We require
structured abstracts for the research papers, in accordance with the Cochrane
review process.
Like all the major journals, we receive
promotional articles sponsored by companies who need third party
literature. Like all the major journals, we request a Declaration of
Interest when the manufacturing company is involved.
As for all the conventional medical
journals, occasional weak papers slip through. I am pleased to hear that
you said the same from the New England Medicine. No peer-review process is
infallible. As we all know, publication is not the end of the scientific
process, fortunately.
The main reasons for rejection of papers is,
weak, unsubstantiated claims, strong unsubstantiated claims, to use a variant of
the quote, "Extraordinary claims demand extraordinary evidence." Trivial,
overblown papers, promotional papers, and what I label suspension of
disbelief. These are papers where the authors are so convinced by what
they believe is true, that they are incapable of objectivity.
These are problems facing all journal
editors, what I see as the unique challenges facing CAM journals, and our
journal specifically is, first of all, paucity of material. I receive
approximately 110 submissions of research review papers in a year.
Secondly, many researchers have not been
exposed to stringent scientific standards. This point keeps being
made. There is a lack of experienced researchers who have CAM experience
and insights. For the same reason, it is hard to find reviewers who
understand the code of expert and impartial review. Another problem is the
non-English speaking authors who have difficulty expressing their ideas clearly.
From unique challenges come unique
opportunities. Dr. Jobst and I, and members of the Board, spend a lot of
time educating and encouraging authors. Rather than reject out of hand, we
help authors to modify their claims. For example, we may require them to
add statements on the limitations of their experiment or methodology, or to
rework the paper.
An another instance, a poorly designed
clinical trial may have potentially interesting preliminary data or insights
that can be converted into a promising case study or a short report.
Unlike some of conventional journals that might throw such papers out, we
actually try to seek out these little gems.
We tolerate successive stages of review and
revision. Most papers go through one major revision stage, but some
require several iterations, so that some papers can take up to two years to get
through the review process. Our rejection rate is low, around 30 percent,
as a result, to a large extent, of our educative policy. The attrition
rate is high. Many authors don't return a revised paper for
reconsideration.
We are open to negative results. I
think the field actually needs some clear negatives, as well as positives, to
enhance credibility. However, authors do not want to publish negative
results. We do have safety studies, and in this most recent issue of the
journal, we have a paper from two naturopathic doctors on the safety of low-dose
lariatridentarta [ph], a retrospective clinical study.
Although the underlying principles of
publication are the same for CAM as for conventional medical journals, as you
say, the sea, the process does have differences. CAM articles published by
conventional journals are predominantly based on the standard pharmaceutical
drug model of isolating and testing single agents or interventions, typically
using the randomized, controlled trial.
At the Journal of Alternative and
Complementary Medicine, we encourage randomized, controlled trials, but we
encourage a broader perspective, too. Our feeling is that new theories
demand innovative methods, and, provided researchers adhere to the basic
scientific principles of external and internal validity, they should be free to
innovate, develop new appropriate methodologies and carefully crafted
techniques.
