In its toughest crackdown yet on medical errors, the federal government is cutting payments to 721 hospitals for having high rates of infections and other patient injuries, records released Thursday show. Medicare assessed these new penalties against some of the most renowned hospitals in the nation, including the Cleveland Clinic, Brigham and Women's Hospital in Boston, the Hospital of the University of Pennsylvania in Philadelphia and Geisinger Medical Center in Danville, Pa. One out of every seven hospitals in the nation will have their Medicare payments lowered by 1 percent over the fiscal year that began Oct. 1 and continues through September 2015.
