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.

Heart attack death rate: 30-day death rate for heart attack patients.
Heart failure death rate: 30-day death rate for heart failure patients.
Pneumonia death rate: 30-day death rate for pneumonia patients.
COPD death rate: 30-day death rate for COPD patients.
CABG surgery death rate: 30-day death rate for CABG surgery patients.
Stroke death rate: 30-day death rate for stroke patients.
Hospital-wide readmission rate: Rate of unplanned readmission within 30 days, all conditions. From 2025 CMS reports the Hybrid Hospital-Wide Readmission measure (claims plus EHR data), which replaced the claims-only measure; values are close but not strictly comparable across the change. CMS suppressed it for 2026.. Latest available: 2025 release.
