About these rankings

Rankings use the 2026 release of CMS Care Compare data. Hospitals share a rank (“T”) when their values are equal, and only hospitals with a reported value for the sorted measure are ranked. Shading compares each value with every hospital in the country, so it doesn’t change with your filters. Small differences are often not statistically meaningful; use the methodology and glossary for context.

C. diff infections: Clostridium difficile (C. diff) intestinal infections (standardized infection ratio; 1.0 = national baseline).

Hospital-wide readmission rate: Rate of unplanned readmission within 30 days, all conditions.
