By now, regular SBM readers should be aware of the Choosing Wisely initiative. Just in case, Choosing Wisely is a campaign developed by the ABIM Foundation to bring together experts from a variety of medical specialties in order to identify common practices that should be questioned by patients and providers, if not outright discontinued. Their ultimate goal was not to establish treatment guidelines or dictate care, but to foster discussion. As I’ve written about in a prior post on the overuse of antibiotics in pediatrics, it doesn’t appear to have caught on. I routinely ask colleagues, residents and students if they are aware of it, and am frequently disappointed by their response.
The American Academy of Pediatrics issued a list of five questionable practices back in February of 2013 and I loved it. All five are important:
- Stop treating viruses with antibiotics
- Stop prescribing and recommending cough and cold medicines for young children
- Stop routine use of CT scans for minor head injuries
- Stop routine use of neuroimaging for simple febrile seizures
- Stop routine use of CT scans for abdominal pain
Imagine a retail pharmacy where some of the medicines on the shelves have been replaced with similar-looking packages that contain no active ingredients at all. There is no easy way to distinguish between the real and the fake.
Another section of the store offers a number of remedies with fantastic claims, such as “boosting” the immune system, “detoxifying” the body, or “cleansing” you of microscopic Candida. They look sciencey, unless you realize that they treat imaginary medical conditions.
A corner of the store offers unpurified drugs supplied as tinctures and teas. The active ingredients aren’t known, and the batch-to-batch consistency of the product is unclear. The store will suggest products for you based on your symptoms.
Walk past the enormous wall of vitamins and other supplements and you’ll find a nutritionist who will tell you what products you should be taking. You’ll also find a weight loss section. From a science-based perspective, this shouldn’t even exist, given no product has been shown to offer any meaningful benefit. But there are dozens of products for sale.
At the back of the store you’ll finally find the pharmacist. A sign on the counter offers blood- and saliva-based tests for food “intolerance” and adrenal “fatigue”, claiming to test for medical conditions that actually don’t exist or lack an evidence base. The pharmacy also offers a large compounding practice, advertising what it calls “personalized” approaches to hormone replacement with “bioidentical” hormones.
Welcome to the “integrative” pharmacy.
You may not see all these features in your local drug store, but they’re coming: claims of a new “integrative” way to provide health care that is changing the face of retail pharmacy. Unfortunately, it’s harkening back to the era of patent medicines and snake oil. It’s not good for the pharmacists and the profession of pharmacy, and it’s even worse for patients. (more…)
There is no alternative medicine. There is only scientifically proven, evidence-based medicine supported by solid data or unproven medicine, for which scientific evidence is lacking. JAMA

Wiser heads than I have commented on “Invitation to a Dialogue: Alternative Therapies” in The New York Times. So why add my two cents? Partly because The New York Times wanted brief responses and I don’t do brief. Partly because I write for me; nothing focuses the mind like putting electrons to LCD, except, perhaps, a hanging. Partly we do need a dialog, just not of the kind suggested by the writer. And partly, life has been so busy of late I needed a topic that required no research. (more…)
A recent opinion piece in The New York Times is an invitation to a dialogue on so-called alternative therapies, written by James Gordon. Gordon directs the Center for Mind-Body Medicine and was chairman of the White House Commission on Complementary and Alternative Medicine Policy appointed by President Bill Clinton. The piece, unfortunately, represents many of the common misconceptions about mainstream medicine and CAM (complementary and alternative medicine).
Even more distressing, the Affordable Care Act will likely reinforce current practice, which dictates surgical and pharmacological interventions that can be expensive, inappropriate, burdened by side effects and, often, ineffective.
His piece is doomed right from the start. Current practice does not “dictate” drugs and surgery, no matter how often CAM proponents claim that it does. This is simply a straw man designed by CAM advocates to create a niche for their brand. Mainstream medicine uses treatments that are backed by sufficient plausibility and evidence, regardless of modality. At least, this is what mainstream medicine strives for. We acknowledge the implementation is imperfect, and improving the standard is part of what we strive for at SBM. (more…)
By far the most common medical problem in newborn infants is jaundice, typically appreciated as a yellowish discoloration of the skin caused by increased blood levels of a pigment called bilirubin. In my role as a newborn hospitalist, I manage jaundice every day. If I am not treating jaundice, in every single baby I see I am at least determining the risk of the child developing jaundice severe enough to require treatment. I then use that assessment to help guide my recommendations on when the infant should follow up with their primary care pediatrician after discharge home.
Fortunately for the millions of infants who develop jaundice every year, in the vast majority it is a self-limited process and often considered to be just a normal part of the first few days of life. But in a significant minority of them, careful management is required in order to prevent complications. Some infants need treatment to prevent neurological symptoms from developing, and to reverse them when they do occur. And in a very small percentage of babies who develop severe jaundice, permanent brain damage and even death can occur.
Because newborn jaundice tends to resolve without any intervention, and complications are now uncommon, it isn’t surprising that a variety of myths and superstitions have arisen that involve preventing or curing the condition. And naturally there are practitioners of unproven alternative medical modalities that can be found claiming to be able to manage it as well. As expected, if you’ve spent any time reading Science-Based Medicine or researching the nonsensical claims of chiropractors, homeopaths and their ilk, their understanding is limited and their recommendations potentially dangerous.
But first a crash course on newborn jaundice. (more…)
There are two topics about which I know a fair amount. The first is Infectious Disease. I am expert in ID, Board Certified and certified bored, by the ABIM. The other, although to a lesser extent, is SCAMs.
When I read the literature on these topics, I do so with extensive knowledge and, in the case of ID, 30 years of clinical experience. The extensive knowledge, and, one hopes, understanding, has led me to read meta-analyses with a grain of salt substitute. They average meta-analysis and systematic review is good for gaining a general understanding of the topic within, as well as, and here is the key phrase, the limitations of the included studies.
And like all the published literature, when writing a meta-analysis, those with an axe to grind will grind it. Even, or perhaps especially, the Cochrane reviews.
Just because something is labelled as a systematic review does not mean it is any good. We have to be just as vigilant now as ever. Even a review with a Cochrane label does not make its true. Four out of 12 Cochrane reviews on acupuncture were wrong. Caveat lector rules, OK? (more…)
Science-based medicine is a concept that is larger than the analysis of any specific topic. It is, essentially, an approach to answering health and medical questions, one that involves careful and thorough analysis of scientific evidence within a framework of understanding of critical thinking, mechanisms of self-deception, and the process of science itself. We feel this creates the best opportunity to arrive at tentative conclusions that are most likely to be reliable.
We often address claims that are the result of a very different process. In fact there seems to be a thriving subculture on the internet that emphasizes the naturalistic fallacy, fear of anything technological (including irrational chemophobia), paranoia about the government, corporations, and mainstream medicine, and embracing anything perceived as being contrarian, exotic, or radical. To this subculture science is either the enemy, or it is used (as Andrew Lang famously quipped) like a drunk uses a lamppost, for support rather than illumination. This approach is simultaneously gullible and cynical.
It is no surprise that those who follow this fatally flawed approach consistently arrive at the wrong conclusion, especially on any controversial scientific topic. The two most prominent netizens following this approach, in my opinion, are Joseph Mercola and Mike Adams. I do believe, however, that there is another hoping to join their ranks – Vani Hari, who blogs under the name Food Babe. (Mark Crislip also blogged about her here.)
“Will Tylenol harm my baby?”
Pharmacists are among the most accessible of health professionals, and so we receive a lot of questions from the public. No appointment required, and the advice is free. Among the most frequent sources of questions are women seeking advice on drug use in pregnancy. This is an area where some health professionals are reluctant to tread. Some prefer to redirect all of these questions to physicians. But physicians are not always easily accessible, and few want to make an appointment just to ask what appears to be a simple question: Is it safe, or not? Admittedly, addressing questions about drug use in pregnancy can be challenging. There are no randomized controlled trials we can look to — there’s only messier, less definitive data. Our responses are filled with cautious hedging about risk and benefit, describing what we know (and don’t know) about fetal effects. In the pharmacy, one of the most common questions from pregnant women is about the use of acetaminophen (aka paracetamol aka APAP), more commonly known by the brand name Tylenol. Google “Tylenol and pregnancy” and you get 4.8 million results. Which source should you trust? (more…)
A comment from the blog:
Every single time – bar none – I have had a conversation with someone about CAM and its modalities, they are absolutely astonished when I explain to them what the modality really is. One story I love telling comes from my friend in the year behind me. His parents are professional chemists and he came home one day and saw his mother had a bottle of homeopathic medicine. He asked why and she gave the typical non-committal response of “well, I thought it may help and I saw it on the shelf at the pharmacy.” He explained what homeopathy actually is and they were absolutely dumbfounded. They are well aware of Avogadro’s number, after all. People generally don’t study what the CAM in question actually is – merely the fluff PR garbage that gets touted around and without direct and clear demonstration of harm, give it a pass as a result. After all, the business of real medicine is time consuming and difficult enough.
Participating in activities that have a permanent record gives one the fortunate, or unfortunate, opportunity to revisit the past and see just how you worked early in a career. (more…)
I glanced at my pharmacy license recently, and noticed I became a licensed pharmacist almost exactly twenty years ago. Two decades seems like a long time to do pretty much anything, yet I can still vividly recall some of the patients I encountered early in my career, working evenings in a retail pharmacy that drew heavily on the alternative medicine crowd. It was the first pharmacy I’d ever seen that sold products like homeopathy, detox kits, salt lamps, ear candles, and magnetic foot pads. And the customers were just as unorthodox. There were some that told me they manipulated their own pH, and others that insisted any prescription drug was designed to kill. And there was a huge clientele that relied on the pharmacy for their “bioidentical” hormones. It was an instructive learning experience, as it was as far from the science of pharmacy school as you could expect to find in a place that still called itself a pharmacy. One of the really interesting aspects of that pharmacy was the enormous supply of vitamins and supplements for sale. It stretched over multiple aisles and even back into where the drugs were kept, as there were some brands kept behind the counter. This wasn’t for any regulatory reason – it was because these were the “naturopathic” supply, the brands often recommended by naturopaths. In order for this pharmacy to sell them they had to keep the products behind the counter, presumably to grant these supplements a veneer of medical legitimacy. After all, they were “special”, and had the prices to prove it. (more…)
