There’s a saying in medicine that we frequently hear when a newer, more effective therapy supplants an older therapy or an existing therapy is shown not to be as efficacious as was once thought, and it has to do about how long it takes for the use of that therapy to decline. The saying basically says that the therapy won’t die out until the current generation of established physicians retire and are replaced by the new generation coming up through medical schools. From my perspective, it’s a bit of an exaggeration, because in the mere 13 years that I’ve been a real doctor (i.e., an attending physician) our practices in breast cancer surgery has changed markedly. Although certain core principles of breast cancer care remain the same, there have been major changes in terms of how we deal with the axillary lymph nodes, our use of hormone therapy and chemotherapy, and our very understanding of the different subtypes of breast cancer. Of course, I have spent my entire career as faculty at two different NCI-designated comprehensive cancer centers; so my experience is not representative of that of most physicians, particularly given that I’m super subspecialized. It’s generally expected that if you’re faculty in an academic medical center you will be at the very least up to date, if not beyond at the cutting edge.
Even so, there is some truth to the observation that it takes the rise of a new generation of physicians to force out certain old ideas, which means that how we train our medical students is of utmost importance. Unfortunately, these days, it is medical students who have become a major force for promoting the “integration” of quackery into medicine (which these days is known as, appropriately enough in a way unintended by its proponents, “integrative medicine”). No, I’m not saying that all or even most medical students are prone to the blandishments of quackademic medicine, but rather that there is a large enough contingent of medical students who have gone beyond being shruggies to become activists for unscientific medicine. There are CAM clubs, CAM interest groups, and student-driven CAM electives.
And then there’s the American Medical Students Association (AMSA), specifically its various initiatives in “integrative medicine.” I fear that each successive generation of medical students is more prone to embracing unscientific medicine than the last.
