Part I:

“We tend to think of medicine as a science, but for most of human history it has been scientific-ish at best. In the first episode of a three-part series, we look at the grotesque mistakes produced by centuries of trial-and-error, and ask whether the new era of evidence-based medicine is the solution.”

Part II:

“How do so many ineffective and even dangerous drugs make it to market? One reason is that clinical trials are often run on “dream patients” who aren’t representative of a larger population. On the other hand, sometimes the only thing worse than being excluded from a drug trial is being included.”

Part III:

“By some estimates, medical error is the third-leading cause of death in the U.S. How can that be? And what’s to be done? Our third and final episode in this series offers some encouraging answers.”
