Rats. Harriet stole what was going to be the title of this post! This is going to be something completely different than what I usually write about. Well, maybe not completely different, but different from the vast majority of my posts. As Dr. Snyder noted on Friday, it’s easy to find new woo-filled claims or dangerous, evidence-lacking trends to write about. Heck, I did it just last week, much to the continued consternation of one of our regular readers and commenters. Examining certain other health-related issues from a science-based perspective is more difficult, but I feel obligated to do it from time to time, not just for a change of pace but to stimulate the synapses and educate myself—and, I hope, you as well—about areas outside of my usual expertise.
We spend a lot of time writing about the scientific basis of medicine, clinical trials, what is and isn’t quackery, and how “complementary and alternative medicine” (CAM) subverts the scientific basis of medicine. However, SBM goes far beyond just that. At least I think of it this way. That’s why I’ve looked at issues that go more to the heart of health policy, which should be based on sound science and evidence. That evidence might take different forms than it does for determining, for example, whether Medicaid results in better health outcomes and by how much health insurance does the same. As is the case with policy issues and economics, conclusions are muddled and messy. The error bars are huge, and the number of potential confounders even huger. (more…)
