CMS Care Compare measures (largely a Medicare population). Rates are this hospital's reported value vs the national figure for the same measure; “better / worse than average” is CMS's own statistical comparison. Mortality, readmission, and infection measures are risk-adjusted; lower is better for those, higher is better for screening, sepsis care, and patient experience. How to read these →
