How this was measured
CMS overall hospital star rating (1 to 5), from the Hospital General Information file. The rating summarizes up to five groups of measures (mortality, safety, readmission, patient experience, timely and effective care); it is not a patient review. Shares are of rated hospitals only, one row per CMS facility number. States with fewer than 10 rated hospitals are not ranked.
Source: CMS Hospital General Information (Provider Data Catalog, dataset xubh-q36u), CMS release October 2026. Figures are a snapshot of that release and are not updated; a later release gets its own report. Not affiliated with CMS.
