Systematic Update Transparency

The U.S. Centers for Medicare & Medicaid Services (CMS) updates its official quality metrics registries incrementally (usually on a quarterly cycle). Hospital Data Center executes structured data checks and processes updates when CMS releases new datasets.

Next Scheduled Synchronization

Our target for the next major database sync is Fall 2026, matching CMS's publication cycle. Individual state corrections are synced bi-weekly.
