Sheetz KH, et al. - In this population-based study of 87 hospitals and 143,174 patients, researchers evaluated the extent to which surgical outcomes varied across hospitals within the networks of the highest-rated US hospitals. Findings revealed that surgical results vary widely across hospitals affiliated with the US News & World Report Honor Roll hospitals. Mechanisms for public reporting should provide patients with information about the quality of all hospitals affiliated with the network. In order to characterize and improve the extent to which a uniform standard of care is delivered, networks should monitor outcome variations.
