Method. Six CMS Care Compare datasets (July 2026 release) are pulled through the data.cms.gov metastore and reduced to one tidy fact table in PostgreSQL. Every benchmark on this page — national and state averages, percentiles, peer-group ranks, the composite — is computed from hospital-level rows; nothing is loaded from a pre-aggregated table. The same computations run here in the browser from a static export of the tables, and in SQL on the SQL tab.

Limitations. One reporting period per measure in this release, so there are no trends. CMS suppresses small-denominator scores; many measures are missing for over half of hospitals (see Measures). Hospital locations are ZIP-centroid approximations. The weighted composite on the Rankings tab is illustrative and is not the CMS Overall Star Rating methodology.
