Worthless back surgeries are a nagging pain for U.S. health care
Abstract: Hospitals performed more than 200,000 unnecessary back surgeries over a three-year period, according to an analysis by the Lown Institute, a health care watchdog group. The useless treatments put patients at risk for complications and cost Medicare about $2 billion, the analysis found. Furthermore, there was a large variation in rates of overuse among individual hospitals, ranging from zero to more than half of procedures.
