Rates are per-100 risk-standardized 7-day hospital visits; "nat" is the national rate for that measure. Rating and Recommend are OAS CAHPS linear mean scores (0–100). A dash means CMS did not report a value — usually too few cases, which is not a bad score.

Sources: CMS Provider of Services file (iQIES, 2026 Q2) for the facility list, specialties and room counts; CMS ASCQR facility-level quality measures; CMS OAS CAHPS patient survey. Metro grouping is by CBSA code 24340; the area name is the U.S. Census Bureau's own title for it, not one we invented.
