The Precision of Standardized Hospitalization, Readmission, and Mortality Ratios for Dialysis Facilities

Standardized ratios are increasingly used as key indexes of quality in "value-based care" and have appeared in a number of health care arenas, such as hospitals.1 Recently, standardized ratios for hospitalization (SHR), readmission (SRR), and mortality (SMR) have been proposed or adopted to assess other smaller health care entities, among them dialysis facilities (see Item S1 for measure specifications).2 Because smaller entities treat fewer patients, calculating standardized ratios for these facilities is inherently based on fewer events, which may result in less statistical power and greater imprecision, as reflected in the variability of score estimates for individual facilities.
