Note: Hospital summary scores were adjusted for social risk factors and the change in their performance quartile and star rating were determined. Shown are the adjusted performance quartile (A) and star rating (B) (table columns) for each original performance quartile (A) or star rating (B) group (table rows). For instance, Table B shows that after SRF risk-adjustment, for hospitals with an original 5-star rating, a single 5-star hospital (0.3%) became a 3-star hospital, 82 5-star hospitals (24.9%) became 4-star hospitals, and 246 5-star hospitals (74.8%) remained 5-star hospitals. Light gray denotes hospitals with no change in performance quartile after risk adjustment; darker gray denotes hospitals that changed 1 performance quartile after risk adjustment.
