Abbreviations: CLABSI, central line-associated bloodstream infection; COPD, chronic obstructive pulmonary disease.

^a Since the star ratings for hospitals range from 1 (worst) to 5 (best), and the outcomes are the reported rates of adverse events, an inverse association (i.e. negative slope) identifies an association between better experience and favorable outcomes. Data for hospital complications (except CLABSI) and readmissions are risk-adjusted rates from Hospital Compare; CLABSI is based on the standardized infection ratio (SIR) from the Centers for Disease Control and Prevention.
