This article  from BusinessWeek is scarily eye-opening—and a clear reminder of the importance of keeping CME evidence-based. From the article:
- he carved out a niche showing doctors at specialty society meetings that their cherished beliefs were dubious. "At each meeting I would do the same exercise," he says. He would ask doctors to think of a typical patient and typical treatment, then write down the results of that treatment. For urologists, for instance, what were the chances that a man with an enlarged prostate could urinate normally after having corrective surgery? Eddy then asked the society's president to read the predictions.
The results were startling. The predictions of success invariably ranged from 0% to 100%, with no clear pattern. "All the doctors were trying to estimate the same thing -- and they all gave different numbers," he says. "I've spent 25 years proving that what we lovingly call clinical judgment is woefully outmatched by the complexities of medicine." Think about the implications for helping patients make decisions, Eddy adds. "Go to one doctor, and get one answer. Go to another, and get a different one." Or think about expert testimony. "You don't have to hire an expert to lie. You can just find one who truly believes the number you want."
