Drawing from data reported by the Leapfrog Hospital Survey, the Agency for Healthcare Research and Quality (AHRQ), the Centers for Disease Control and Prevention (CDC), and the Centers for Medicare and Medicaid Services (CMS), this website provides grades for hospitals in the United States based on their safety. The Spring 2024 hospital safety grade results document improvements in healthcare associated infections and patient experience scores. A new data set shares the numbers of hospitals from large metropolitan areas with A grades.
