• Provider of Services: the certification, provider type, beds and status.
• Medicare Care Compare: the star rating and every measure on this page, with the state and national rates CMS publishes beside them.
• NPPES NPI Registry: the NPI records connected to this certification.

Better and worse are CMS's own comparison with the national rate, not ours: for most measures a low score is the good one (deaths, infections) and for others a high one is, so measures where CMS states no comparison are left uncoloured. The exception is star ratings, which are read against the national average here. Quality measures are published by CMS and are not adjusted or re-scored here. Averages marked “computed here” are the mean of every facility reporting that measure, worked out by NPIMap because CMS publishes no comparison for it. Confirm anything you rely on at Medicare Care Compare.
