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.
