Abstract
Background—: Reducing readmissions for heart failure is an important goal for policymakers. Current national policies financially penalize hospitals with high readmission rates, which may have unintended consequences if these institutions are resource-poor, either financially or clinically. Methods and Results—: We analyzed national claims data for Medicare patients with heart failure discharged from US hospitals in 2006 to 2007. We used multivariable models to examine hospital characteristics, 30-day all-cause readmission rates, and likelihood of performing in the worst quartile of readmission rates nationally. Among 905 764 discharges in our sample, patients discharged from public hospitals (27.9%) had higher readmission rates than nonprofit hospitals (25.7%, P P P P P <0.001). These same characteristics identified hospitals that were likely to perform in the worst quartile nationally. Conclusions—: Given that many poor-performing hospitals also have fewer resources, they may suffer disproportionately from financial penalties for high readmission rates. As we seek to improve care for patients with heart failure, we should ensure that penalties for poor performance do not worsen disparities in quality of care.
