Health and Wellness Coaching: cautious optimism and some concerns

NCCHWC logo

The National Consortium for Credentialing of Health & Wellness Coaches (NCCHWC) and the National Board of Medical Examiners (NBME) signed an agreement last month for the launch of a national certification for individual health and wellness coaches in the U.S. According to a joint press release, the agreement is a landmark in the efforts of a dedicated group of individuals who have been working for years to establish professional practice and educational standards for health and wellness coaching.

What is “health and wellness coaching?” According to NCCHWC’s website:

Health and Wellness Coaches partner with clients seeking self-directed, lasting changes, aligned with their values, which promote health and wellness and, thereby, enhance well-being. In the course of their work health and wellness coaches display unconditional positive regard for their clients and a belief in their capacity for change, and honoring that each client is an expert on his or her life, while ensuring that all interactions are respectful and non-judgmental.

No, a rat study with marginal results does not prove that cell phones cause cancer, no matter what Mother Jones and Consumer Reports say

The zombie story that cell phones cause cancer has risen from the grave yet again.

The zombie story that cell phones cause cancer has risen from the grave yet again.

There are certain myths that are frustratingly resistant to evidence, science, and reason. Some of these are basically medical conspiracy theories, where someone (industry and/or big pharma and/or physicians and/or the government) has slam-dunk evidence for harm but conspires to keep it from you, the people. For example, despite decades worth of negative studies, the belief that vaccines are harmful, causing conditions ranging from autism to sudden infant death syndrome, to all varieties of allergies and autoimmune diseases, refuses to die. Fortunately, this myth is one that, after more than a decade of hammering by scientists, skeptics, and public health advocates, has finally taken on enough of the patina of a fringe belief that most mainstream news sources no longer feel obligated to include the antivaccine side in stories about vaccines for “balance.” It is a zombie myth, one that, no matter how often it is “killed,” always seems to rise again. Unfortunately, the same cannot be said for the myth that cell phones cause cancer, as some very credulous reporting late last week demonstrated in the form of headlines like this:

National Academy of Sciences Report on GMOs

NASGMOreportDespite the fact that numerous scientific and health organizations around the world have examined the evidence regarding the safety of genetically modified organisms (GMOs) and found them to be completely safe, there remains a public controversy on this topic. In fact a Pew Poll found that while 88% of AAAS scientists believe that GMOs are safe for human consumption, only 37% of the public do – a 51% gap, the largest in the survey.

This gap is largely due to an aggressive anti-GMO propaganda campaign by certain environmental groups and the organic food industry, a competitor which stands to profit from anti-GMO sentiments. There is also a certain amount of generic discomfort with a new and complex technology involving our food.

Because of all this, the National Academy of Sciences put together an expert committee to systematically review all the evidence regarding this new technology. Their thorough 407 page report is now available.

They pulled together experts with diverse backgrounds, and also took public comment and solicited input from a wide range of interests. They decided specifically not to rely on any previous review, but to conduct their own review of the primary literature. (more…)

Are medical errors really the third most common cause of death in the U.S.?

NOTE: Anyone who has seen several derogatory articles about me on the web and is curious about what the real story is, please read this and this.

Dr. Martin Makary claims that medical errors are now the third leading cause of death in the US. Is he correct?

Dr. Martin Makary claims that medical errors are now the third leading cause of death in the US. Is he correct?

It is an unquestioned belief among believers in alternative medicine and even just among many people who do not trust conventional medicine that conventional medicine kills. Not only does exaggerating the number of people who die due to medical complications or errors fit in with the world view of people like Mike Adams and Joe Mercola, but it’s good for business. After all, if conventional medicine is as dangerous as claimed, then alternative medicine starts looking better in comparison.

In contrast, real physicians and real medical scientists are very much interested in making medicine safer and more efficacious. One way we work to achieve that end is by using science to learn more about disease and develop new treatments that are as efficacious or more so than existing treatments with fewer adverse reactions (clinical equipoise). Another strategy is to use what we know to develop quality metrics against which we measure our practice. Indeed, I am heavily involved in just such an effort for breast cancer patients. Then, of course, we try to estimate how frequent medical errors are and how often they cause harm or even death. All of these efforts are very difficult, of course, but perhaps the most difficult of all is the last one. Estimates of medical errors depend very much on how medical errors are defined, and whether a given death can be attributed to a medical error depends very much on how it is determined whether a death was preventable and whether a given medical error led to that death.

Overprescribing Antibiotics

Phial of penicillin from 1946, marking the advent of the now-closing "antibiotic era".

Recently I had a cutaneous abscess which was treated (quite painfully) with incision and drainage. My doctor told me that antibiotics were not strictly necessary, but I could have them if I wanted. The idea of any treatment that could resolve the abscess more quickly was appealing, but I did not want to contribute to the unnecessary use of antibiotics so I declined.

The use of antibiotics in cutaneous abscess is not straightforward, as there are indications – signs of systemic infection, failure to resolve quickly with just I&D, or in immunocompromised patients. Antibiotics may also reduce the risk of recurrence. These are, after all, bacterial infections.

If I were not very familiar with the issue of antibiotic overuse and emerging resistance I probably would have caved and accepted the antibiotics, and I suspect most patients do. Many patients probably request antibiotics or at least ask about them. I declined, and everything turned out fine. (more…)

Medical exemptions to vaccine mandates for sale after SB277! Get ’em before they’re gone!

NOTE: Anyone who has seen several derogatory articles about me on the web and is curious about what the real story is, please read this and this.

SB277, which eliminates nonmedical exemptions to school vaccine mandates in California, is a very good law, but it's not perfect. Unfortunately, one provision allows the issuance of medical exemptions based on the say-so of doctors using antivaccine misinformation and pseudoscience.

SB277, which eliminates nonmedical exemptions to school vaccine mandates in California, is a very good law, but it’s not perfect. Unfortunately, one provision allows the issuance of medical exemptions based on the say-so of doctors using antivaccine misinformation and pseudoscience.

I realize that it’s a cliché to say so, but some clichés are true. Time really does fly. It’s hard to believe that a year ago California—and, by proxy, the rest of the country—was in the throes of a major political war over the bill SB277. SB277, you will recall, was a bill introduced into the California Assembly in the wake of the Disneyland Measles outbreak in early 2015 that eliminated non-medical exemptions to school vaccine mandates beginning with the 2016-2017 school year. Ultimately, SB277 passed and was signed into law by Governor Jerry Brown last July. It was an uncommon victory for science and public health, and already appears to be having a positive effect on vaccine uptake in kindergarten children.

Unfortunately but not unexpectedly, to say that the proposal and passage of SB277 into law drove the antivaccine movement into even greater fits of crazy in response is to put it mildly. It became a common trope on antivaccine websites and blogs to see SB277 compared to fascism, in particular the Holocaust. Robert F. Kennedy, Jr. and “Dr. Bob” Sears explicitly compared SB277 to the Holocaust. Truly, the Godwin was strong in the antivaccine movement. One particularly offensive meme that went around at the time consisted of antivaccinationists suggesting that SB277 was a major step in the direction of requiring unvaccinated children to wear a badge or armband to identify themselves, the way that the Nazis required Jews to wear badges or armbands with a yellow Star of David on them. One, Heather Barajas, even went so far as to be photographed with her children wearing such an “unvaccinated” badge and juxtapose that photo with photos of Jews from the Third Reich wearing yellow Stars of David.

Reclassifying thyroid cancer and the willful misunderstanding of overdiagnosis

This is a panel showing some of the pathologic criteria for distinguishing invasive encapsulated follicular variant of papillary thyroid carcinoma from noninvasive. This is real science. Sayer Ji's rant is not.

This is a panel showing some of the pathologic criteria for distinguishing invasive encapsulated follicular variant of papillary thyroid carcinoma from noninvasive. This is real science. Sayer Ji’s rant is not.

If there’s one lesson that we here at Science-Based Medicine like to emphasize, it’s that practicing medicine and surgery is complicated. Part of the reason that it’s complicated is that for many diseases our understanding is incomplete, meaning that physicians have to apply existing science to their treatment as well as they can. The biology of cancer, in particular, can be vexing. Some cancers appear to progress relentlessly, meaning that it’s obvious that all of them must be treated. Others, particularly when detected in their very early stages through screening tests, have a variable and therefore difficult to predict clinical course if left untreated. Unfortunately, some people, such as Sayer Ji, don’t understand that. They like their medicine black and white, and if physicians ever change guidelines in order to align them more closely with scientific understanding, they write blisteringly ignorant articles like “‘Oops… It Wasn’t Cancer After All,’ Admits The National Cancer Institute/JAMA.”

Not exactly. An expert panel recommended reclassifying a specific thyroid lesion as not cancerous based on recent science. It’s called medicine correcting itself. Admittedly, this reclassification was probably long overdue, but what would Mr. Ji rather have? Medicine not correcting itself in this situation? In any case, when last I met Mr. Ji, he was happily abusing the science of genetics to argue that Angelina Jolie and other carriers of deleterious cancer-causing mutations don’t need prophylactic surgery because lifestyle interventions will save them through epigenetics, which to “natural health” enthusiasts like Mr. Ji seems to mean the magical ability to prevent any disease. Most recently, he has appeared on the deeply dishonest “documentary” about alternative medicine cancer cures, The Truth About Cancer, to expound on how chemotherapy is evil. His rant about the reclassification of a non-encapsulated follicular variant of papillary thyroid cancer as not cancer is more of the same, as you will see.

Statins for everyone? Not so fast.

In rosuvastatin we trust?

In rosuvastatin should we trust?

People love the idea of preventive medicine. Preventing a disease, before it occurs, seems intuitively obvious. But when it comes to taking medicine to prevent a disease before it occurs, people tend to be much less comfortable. Not only are there the concerns about the “medicalization” of healthy people, there are good questions about benefits, risks, and costs. Cardiovascular disease will kill many of us, so there’s been decades of research studying how to prevent that first heart attack or stroke. But even if you’re born with good genes and do everything possible to prevent heart disease (e.g., don’t smoke, exercise regularly, eat a healthy diet, moderate your alcohol, and keep your weight down) you’re still at risk of heart disease. And if you have one or more risk factors for disease, your lifetime risk goes up dramatically. Once you’ve had your first heart attack or stroke, the effectiveness of medical therapy is clear. Drug therapy with medication like the “statins” class of cholesterol-lowering drugs reduces deaths from cardiovascular disease. Given their unambiguous effectiveness, and the high likelihood that many of us will eventually have cardiovascular disease of some sort, the idea of “pre-treating” otherwise-healthy people with drug therapy to possibly prevent that first event has been held out as a potential public health strategy. There’s new evidence that tests this hypothesis, and the results are surprising. (more…)

Why Antibiotic Use Scares Me

Editor’s note: Today we present a guest post from fourth-year medical student Joshua Horton, about the looming problem of antibiotic resistance. Welcome!

Antibiotic sensitive (left) and resistant (right) bacterial colonies. They probably shouldn't be that close together.

Antibiotic sensitive (left) and resistant (right) bacterial colonies. They probably shouldn’t be that close together.

I read a study recently that alarmed me: acute bronchitis is a condition that rarely requires antibiotics, but three quarters of patients presenting with this condition receive a prescription for antibiotics. Even more worrisome, this statistic has not changed in 20 years. To those of us on the cusp of a career in medicine – I am a fourth year medical student – this is terrifying because we are going to have to deal with the consequences. Antibiotic overuse leads to:

  • Increased morbidity and mortality for patients infected with resistant bugs
  • Unnecessary and exorbitant healthcare expenditures
  • The potential to cultivate multi-resistant bacteria that could spread to pandemic proportions

We still take them for granted, but antibiotics are a finite resource. Each time we breed a bug that is resistant to a particular drug, we are forced to relinquish that gun from our armamentarium. With fiscal impetus for pharma to develop new antibiotics waning, we may have reached a point of no return. That’s why this study scared me. Hopefully, clever techniques based on behavioral theory designed to reduce antibiotic prescribing may pull us back from that edge – read on to learn more. (more…)

American Journal of Public Health article touts “potential public health benefits” of homeopathy

Homeopathy: It's just water.

Homeopathy: It’s just water.

An article in the April, 2016 issue of the American Journal of Public Health caught my eye: “Homeopathy Use by US Adults: Results of a National Survey.” I was pleased to see that homeopathy use is actually quite low. The 2012 National Health Survey found that only 2.1% of U.S. adults used homeopathy in the last 12 months, although that was a 15% increase over 2007. Users were mostly young, white, well-educated women, the typical CAM consumer.

Even fewer saw a homeopathic practitioner (only 19% of all users), although those who did perceived a greater benefit from homeopathic remedies. This difference, speculate the authors, could be due to several factors, one of which is

a more individualized and effective homeopathic prescription by the provider.

What? Are the authors suggesting that the series of off-the-wall questions asked by homeopaths leads to a prescription of an “effective” homeopathic remedy?

They certainly seem to be. Who are these authors, anyway?

They are Michelle L. Dossett, MD, PhD, MPH, Roger B. Davis, ScD, Ted J. Kaptchuk, and Gloria Y. Yeh, MD, MPH. All are, or were, with the Division of General Medicine and Primary Care, Beth Israel Deaconess Medical Center. All are also connected with Harvard and work, in various ways, in “integrative medicine” research. The article was funded, in part, by the National Center for Complementary and Integrative Health, and in part by Harvard. (more…)
