NCCAM: the not-even-wrong agency

The National Center for Complementary and Alternative Medicine (NCCAM) is a government agency tasked with (among other things), “[exploring] complementary and alternative healing practices in the context of rigorous science.” In this space we have talked about NCCAM quite a bit, but I have to admit that I don’t think about them very much. The other day, though, I was reading though JAMA and I came across a study funded by the agency. The study, which showed that Ginkgo does not prevent Alzheimer’s-type dementia, was pretty good, so I cruised on over to NCCAM’s website to see what else they’ve been up to.

A quick glance at NCCAM’s front page:

    “Ginkgo Evaluation of Memory (GEM) Study Fails To Show Benefit in Preventing Dementia in the Elderly”
    “CAM and Hepatitis C: A Focus on Herbal Supplements ‘No CAM treatment has yet been proven effective for treating hepatitis C or its complications.’”
    “Selenium and Vitamin E in Prostate Cancer Prevention Study, ‘selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer.’”

It seems that NCCAM is finding out something we already strongly suspected:  improbable medical claims are usually wrong.  Since that’s not how they see things,  and since I don’t believe that there is such a thing as alternative medicine, I was curious how they defined CAM.

CAM is a group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine. Conventional medicine is medicine as practiced by holders of M.D. (medical doctor) or D.O. (doctor of osteopathy) degrees and by their allied health professionals, such as physical therapists, psychologists, and registered nurses. Some health care providers practice both CAM and conventional medicine. While some scientific evidence exists regarding some CAM therapies, for most there are key questions that are yet to be answered through well-designed scientific studies–questions such as whether these therapies are safe and whether they work for the diseases or medical conditions for which they are used.

The list of what is considered to be CAM changes continually, as those therapies that are proven to be safe and effective become adopted into conventional health care and as new approaches to health care emerge. emphasis mine, ed.

The list of NCCAM studies appears to fall into three broad categories.

Canadian Justice: Breast-Fondling Chiropractor Faces “Interpersonal Skills Training”

There is something unexpectedly sinister about this news report from my former home town in Canada. Apparently, a local chiropractor has been using his “medical training” to excuse his sexual misconduct. Here’s the story from the Halifax Chronicle Herald:

During a hearing in July, the woman said the chiropractor would frequently grip her around the ribs and hold tight, sometimes cupping her breasts, while speaking softly over her shoulder.

On other visits, she said, he would have her lie on a table and would undo one side of her johnny shirt, exposing her breast, place a thumb between her breasts and roll her onto her side by pressing the weight of his own body on her.

Dr. LaPierre testified he performed a technique called the Zindler manoeuvre. It involves applying precise, quick pressure to a restricted joint to restore movement. He said he would have explained the procedure to her the first time but not on subsequent treatments…

The second incident involved a woman who complained that in 2006 the chiropractor “massaged” her breast while trying to find the source of her back pain.

Dr. LaPierre said he was using a technique called “matrix repatterning” that required contact with the woman’s sternum. He said he didn’t recall where the rest of his hand was at the time. He determined the woman had a rib out of alignment.

What was the punishment for his behavior?

Dr. Phillip LaPierre must have a female observer present when he examines women for the next five years, must take training on interpersonal skills and must pay a fine and costs totaling $26,000 now that a panel of the Nova Scotia College of Chiropractors has found him guilty of sexual misconduct based on the two complaints.

It’s hard to imagine such a small fee in an American court of law. If a US physician were molesting his patients, I’m willing to bet that the fine would have an additional zero or two at the end.

Does alternative medicine have alternative ethics?

Kimball Atwood has an interesting series of posts on the ethics of alternative medicine which I strongly encourage you to read.  He does a great job examining the ethical implications of certain alternative medicine practices, and has a terrific dialog with Peter Moran, a frequent commenter here.   At my other online locale, I make frequent forays into the morass of medical ethics, with an emphasis on specific clinical scenarios.  Today, though, I’d like to take a step back and examine the nature of medical ethics as they apply to so-called alternative medicine.

First, and perhaps most important, I am not an ethicist.  I do not have the depth of reading, the knowledge of terminology, or the specific education to lead a formal discussion on ethics.  What I am is a practicing internist, who must make ethical decisions on a daily basis. Most of these decisions are of necessity made “from the heart”, but it is not infrequent that I must evaluate a situation more formally and fall back on some of the ethical principles of my profession.

Ethics are not static.  They are not a divine gift bestowed on each of us as we don our white coats.  They are a living part of our specific cultures, and of the profession we serve.  Some of the modern principles of medical ethics are newer than others.  Beneficence, non-maleficence, and confidentiality are ancient principles of medical ethics, which continue to be relevant today.  Patient autonomy is a more recent value, reflecting a shift in how society views the relationship between patient and physician.  These ethics must be mutable, as the profession itself is ever-changing.  Despite this fluidity, there is an identifiable line of “doctor-hood” that has existed for at least the last century, and the members of this guild have always tried to adhere to some type of code of behavior.

Alternative medicine poses real challenges to the principle of medical ethics.  First, we’ll discuss who, in fact, is bound by these principles, then the way in which alternative medicine is or is not compatible with medical ethics. (more…)

Placebos in the news again

ResearchBlogging.orgTowards the end of last week, I was contemplating what I would be writing about for Monday. No topic had quite floated my boat, but I hated to dip into the archive of topics I’ve written about before to update a post. After all, I like to be topical whenever possible. Then what to my wondering eyes should appear (yes, I know Christmas is still two months away) but a study in the British Medical Journal by a group lead by Jon C. Tiburt at the Department of Bioethics at the National Institutes of Health in collaboration with investigators at the Osler Institute at Harvard University and the McClean Center for Clinical Medical Ethics at the University of Chicago entitled Prescribing “placebo treatments”: results of national survey of US internists and rheumatologists.

Serendipity? Who cares? The study addresses a very important aspect of science-based medicine.

Trick or Treatment

I’ve just finished reading Trick or Treatment: The Undeniable Facts about Alternative Medicine by Simon Singh and Edzard Ernst. I’d been looking forward to the publication of this book, and it exceeded my expectations.

Edzard Ernst, based at the University of Exeter in England, is the world’s first professor of complementary medicine, a post he has held for 15 years. An MD and a PhD, he also embraced alternative medicine and used to practice homeopathy. He has done extensive research and published widely. His stated objective is “to apply the principles of evidence-based medicine to the field of complementary medicine such that those treatments which demonstrably do generate more good than harm become part of conventional medicine and those which fail to meet this criterion become obsolete.” His most important accomplishment has been to “demonstrate that complementary medicine can be scientifically investigated which, in turn, brought about a change in attitude both in the way the medical establishment looks upon complementary medicine and in the way complementary medicine looks upon scientific investigation.”

Simon Singh is a science writer with a PhD in particle physics. As a team, he and Ernst are uniquely qualified to ferret out the truth about alternative medicine and explain it to the public. (more…)

The National Center for Complementary and Alternative Medicine (NCCAM): Your tax dollars hard at work

What’s an advocate of evidence- and science-based medicine to think about the National Center for Complementary and Alternative Medicine, better known by its abbrevation NCCAM? As I’ve pointed out before, I used to be somewhat of a supporter of NCCAM. I really did, back when I was more naïve and idealistic. Indeed, as I mentioned before, when I first read Wally Sampson’s article Why NCCAM should be defunded, I thought it a bit too strident and even rather close-minded. At the time, I thought that the best way to separate the wheat from the chaff was to apply the scientific method to the various “CAM” modalities and let the chips fall where they may.

Two developments over the last several years have led me to sour on NCCAM and move towards an opinion more like Dr. Sampson’s. First, after its doubling from FY 1998-2003, the NIH budget stopped growing. In fact, adjusting for inflation, the NIH budget is now contracting. NCCAM’s yearly budget remains in the range of $121 million a year, for well over $1 billion spent since its inception as the Office of Alternative Medicine in 1993. Its yearly budget contains enough money to fund around 75 to 100 new five year R01 grants, give or take. In tight budgetary times my view is that it is a grossly irresponsible use of taxpayer money not to prioritize funding for projects that have hypotheses behind them that have a reasonable chance of being true. Scarce NIH funds should not be for projects that have as their basis hypotheses that are outlandishly implausible from a scientific standpoint. Second, I’ve seen over the last few years how NCCAM is not only funding research (most of which is of the sort that wouldn’t stand a chance in a study section from other Institutes or Centers)) but it’s funding training programs. Indeed, that was the core complaint against NCCAM: that it facilitates and promotes the infiltration of nonscience- and nonevidence-based treatments falling under the rubric of so-called “complementary and alternative” or “integrative” medicine into academic medicine. However, NCCAM cannot do otherwise, given its mission:

  • Explore complementary and alternative healing practices in the context of rigorous science.
  • Train complementary and alternative medicine researchers.
  • Disseminate authoritative information to the public and professionals.

If, in fact, NCCAM actually did devote itself solely to “rigorous science” with regard to “alternative” healing practices, I would have much less problem with it than I do. However, it broadly interprets the second and third parts of its mission. For example, it views part of its mission as promotion, rather than study: “Supporting integration of proven CAM therapies. Our research helps the public and health professionals understand which CAM therapies have been proven to be safe and effective.” This would be all well and good if NCCAM had as yet actually proven any CAM therapies to be at least effective, but it has not. Worse, it has not even managed to demonstrate any of them to be ineffective, either, thus leading to endless studies of modalities that either do not work or at the very least would have marginal efficacy.

Still, I thought; All questions of promotion of CAM modalities aside, least there’s the science. Surely, under the auspices of the NIH, NCCAM must be funding some high-quality studies into CAM modalities that couldn’t be done any other way. That thought died when NCCAM announced last week the studies that it had funded during FY 2007.

On the nature of “alternative” medicine cancer cure testimonials

No doubt you’ve come across them before, either on the Internet, printed advertisements, or radio and TV ads: Alternative medicine cancer “testimonials.” They are the primary means by which “alternative” therapies for cancer (or just about any other disease) are promoted and the primary “evidence” that is used to “prove” the efficacy of non-evidence-based therapies. There’s no doubt that they sure can sound convincing. Typically, what you will see or hear is a chipper-looking and -sounding person who claims that this treatment “cured” his or her cancer. These testimonials almost always include many or all of these elements: First, the cancer patient receives the diagnosis, after which she is lost and suffering at the hands of “conventional” doctors, who either cannot or do not wish to understand and who cannot do anything for her. Often, this will take the form of the classic alt-med cliche that the patient was “sent home to die.” Then, when all hope seems lost, the patient discovers an alternative medicine “healer” or treatment. It is not infrequently described in quasireligious terms, like a revelation or something that brings the patient out of the darkness and into the light. Naturally, there is resistance from the patient’s doctors, family, and/or friends, who warn against it, with doctors warning of dire consequences if the patient abandons conventional medicine. But the patient, convinced by dubious practitioners, friends, and, of course, previous testimonials, “sees” that the treatment “works” in a way that medical science cannot and survives. Infused with fervor, the patient now wants to spread the word. Often, the patient is now selling the remedy. Perhaps you’ve seen such testimonials or heard them on the radio and thought: “Gee, this sounds great. I wonder if it works.”

The answer is: Almost certainly not.
