Approximately 1% of all physicians account for 32% of paid malpractice claims (New England Journal of Medicine, January 28, 2016). Using the National Practitioner Data Bank as their resource, Stanford medical law expert David M. Studdert and his colleagues concluded that "a small number of physicians with distinctive characteristics accounted for a disproportionately large number of paid medical malpractice claims" from 2005 through 2014. Over this 10-year period, there were 66,427 claims paid against 54,099 physicians. A physician with three paid claims was found to have three times the risk of incurring another paid claim when compared to a physician who had only one previous claim. The vast majority of these claims were out-of-court settlements, and one-third involved alleged negligence leading to patient death.
