This story looked at how effective medical boards are at stopping dangerous doctors from practicing medicine. We used a state database to identify the 25 Florida doctors with the most malpractice payouts since 2000. We then looked at how many of these doctors had been stopped from practicing by the Florida Board of Medicine. Turns out, just four of them lost their licenses - and three of those four only lost them after they had been arrested and charged with either drug trafficking or billing fraud. The fourth lost his license after he failed to comply with the terms of a lesser punishment. In other words, not a single one of them had been stopped from practicing due to poor medical care.
