Competition and the impact of online hospital report cards

Abstract

Information on the quality of healthcare gives providers an incentive to improve care, and this incentive should be stronger in more competitive markets. We examine this hypothesis by studying Pennsylvanian hospitals during the years 1995-2004 to see whether those hospitals located in more competitive markets increased the quality of the care provided to Medicare patients after report cards rating the quality of their Coronary Artery Bypass Graft programs went online in 1998. We find that after the report cards went online, hospitals in more competitive markets used more resources per patient, and achieved lower mortality among more severely ill patients.
