MALPRACTICE SUITS ARE a feared, often infuriating, and common event in a doctor’s life. (I have not faced a bona fide malpractice suit yet, but I know to expect one.) The average doctor in a high-risk practice like surgery or obstetrics is sued about once every six years. Seventy percent of the time, the suit is either dropped by the plaintiff or won by the doctor in court. But the cost of defense is high, and when doctors lose, the average jury verdict is half a million dollars.
