Appropriateness and Outcomes of Percutaneous Coronary Intervention at Top-Ranked and Nonranked Hospitals in the United States.
OBJECTIVES: This study sought to compare the appropriate use and outcomes of percutaneous coronary intervention (PCI) between top-ranked and nonranked hospitals. BACKGROUND: The U.S. News & World Report "Best Hospitals" rankings are an influential consumer-directed publication of hospital quality, and are commonly used in promotional campaigns by hospital systems. METHODS: Hospitals in the National Cardiovascular Data Registry CathPCI registry between July 1, 2014, and June 30, 2015, were classified as top-ranked if they were included in the 2015 U.S. News & World Report 50 best "Cardiology and Heart Surgery" hospitals. The remaining were classified as nonranked. We compared in-hospital mortality, post-procedural bleeding, post-procedural acute kidney injury, and the proportion of appropriate PCI procedures between top-ranked and nonranked hospitals. RESULTS: A total of 509,153 PCIs at 654 hospitals were included, of which 55,550 (10.9%) were performed at 44 top-ranked hospitals. After adjusting for patient case mix, PCIs performed at top-ranked hospitals had similar odds of in-hospital mortality (adjusted odds ratio [aOR]: 0.96; 95% confidence interval [CI]: 0.83 to 1.12; p = 0.64), acute kidney injury (aOR: 1.10; 95% CI: 0.98 to 1.22; p = 0.099), and bleeding (aOR: 1.15; 95% CI: 0.99 to 1.31; p = 0.052). Top-ranked hospitals had a slightly lower proportion of appropriate PCI compared with nonranked hospitals (89.2% vs. 92.8%; OR: 0.56; 95% CI: 0.45 to 0.69; p < 0.001). CONCLUSIONS: PCI performed at top-ranked hospitals was not associated with superior outcomes compared with PCI at nonranked hospitals. The inclusion of metrics based on clinical data may be important for hospital quality rankings.
