Sarah Kliff explains:
They sound like some of the worst mistakes a surgeon could make: Leaving an instrument inside a patient. Operating on the wrong body part — or the wrong person. They’re aptly named "never" events, the errors that should never, ever occur. Turns out, however, these "never" events happen quite frequently, about 500 times a year. Between September 1990 and September 2010, new research in the journal Surgery found evidence of 9,744 paid malpractice claims for never events.
