Malpractice claims against U.S. doctors are often dismissed, and when they go to trial, the verdict is usually in the doctor's favor, according to a new study. But even when a case is dismissed, the road is typically long for both doctors and the patients suing, researchers said. Medical malpractice claims have become a hot-button issue in the U.S., coming up repeatedly in debates about healthcare reform. Some specialists must pay a couple hundred thousand dollars a year in premiums for insurance against malpractice claims—though rates vary by state. But not much has been known about how long malpractice claims take to resolve, or what proportion of them actually end in a payment to patients, according to Jena.
