About the data

Every designation needs a source.

The registry publishes only records collected from approved official sources and matched to licensed facilities.

Normalized records

Facilities, states, counties, designation taxonomy, certifying bodies, certifications, and verification events are separate entities. One hospital can carry multiple source-backed designations.

Controlled refreshes

Imports validate records, deduplicate within counties, compare designation changes, and create audit and review records before publication.

Traceable provenance

Every certification includes its official source URL and last verified date. Missing dates remain unpublished rather than inferred.

Current coverage

The bundled production snapshot contains California EMSA adult Level I–III trauma centers and California clinical-care cancer centers verified in the public NCI directory. Joint Commission, DNV, AHA, heart attack designation, and STS CABG adapters publish nothing until an authorized file or approved feed is supplied.

Identity matching

Source names are constrained by county, normalized, checked against documented aliases, and scored. Low-confidence matches enter the manual review queue. The source designation is never replaced with a claim from a hospital marketing page.
