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.

Left ED without being seen: Percentage of patients who left the emergency department before being seen.
Time in emergency department: Median time patients spent in the emergency department before leaving.
Appropriate sepsis care: Percentage of patients who received appropriate care for severe sepsis and septic shock.
Health care workers vaccinated for flu: Percentage of health care workers given influenza vaccination.
