One measure shown per center — the one with reportable case volume. Every center reports on a different mix, which is why the full grid below is worth reading.

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.
