# CMS Care Compare Hospital Quality Measures (mortality / readmissions / timely / infections / imaging / maternal)

`medicare_silver.fact_hospital_quality_measure` · Hospital price transparency · status live · 510,084 rows

Long-format hospital quality measures from the CMS Provider Data Catalog (Care Compare), unioned across SIX source datasets into one fact, partitioned by measure_source: "Complications and Deaths" (mortality + complication rates), "Unplanned Hospital Visits" (readmission / ED-return rates), "Timely and Effective Care" (timeliness), "Healthcare Associated Infections" (HAI / SIR), "Outpatient Imaging Efficiency" (appropriate-imaging measures), and "Maternal Health" (maternal-care measures). Each row carries the raw score string + a parsed score_numeric, plus compared-to-national, denominator/sample, lower/higher estimate, footnote, and the measurement start/end dates. The QUALITY axis joinable by CCN to the hospital chargemaster spine — i.e. expensive-and-low-quality detection.

**Grain.** One row per (measure_source, hospital CCN, measure_id) — the measure score + bounds.
