 Evaluating hospital performanceGerald Pruckner and Thomas Schober No 2025-03, Economics working papers from Department of Economics, Johannes Kepler University Linz, Austria Abstract: Patient selection remains a major challenge in evaluating hospital perfor mance. We exploit the quasi-random assignment of patients to hospitals, based on a rotation schedule between hospitals in the Upper Austrian capital of Linz. In the instrumental variable (IV) framework, we use high-quality administrative data and estimate hospital performance on patient outcomes such as mortality and readmission. We contrast these results with those of traditional risk adjustment models based on patient observables. We find that the assessment of hospital performance is sensitive to the inclusion of patient observables and that increasing the number of socio economic covariates to better control for patient risk profiles does not always help bring risk-adjusted estimates closer to IV estimates. Our results sug gest that common risk adjustment does not adequately control for patient differences between hospitals and that hospital quality indicators based on common administrative data should be interpreted with caution. The trend toward personalized medicine may support the process of collecting more clinical information at the individual level, thus allowing for better quality comparisons between hospitals.
