For my first blog entry, I wanted to write about something important, and I couldn’t think of anything more important than a recent book by R. Barker Bausell: Snake Oil Science: The Truth About Complementary and Alternative Medicine. If you want to understand how medical research works, if you want to know what can lead patients and scientists to false conclusions, if you have ever used complementary or alternative medicine or have wondered why others do, if you value evidence over belief, if you care about the truth, you will find a treasure trove of information in this book.
Some of the treatments encompassed under “complementary and alternative medicine” (CAM) have been around for a long time. Before we had science, “CAM” was medicine. Back then, all we had to rely on was testimonials and beliefs. And even today, for most people who believe CAM works, belief is enough. But at some level, the public has now recognized that science matters and people are looking for evidence to support those beliefs. Advocates claim that recent research validates CAM therapies. Does it really? Does the evidence show that any CAM therapy actually works better than placebos? R. Barker Bausell asks that question, does a compellingly thorough investigation, and comes up with a resounding “NO” for an answer.
Bausell is the ideal person to ask such a question. He is a research methodologist: he designs and analyzes research studies for a living. Not only that: he was intimately involved with acupuncture research for the National Center for Complementary and Alternative Medicine (NCCAM). So when he talks about what can go wrong in research and why much of the research on CAM is suspect, he is well worth listening to.
