The Leapfrog Group annually ranks the nation’s hospitals. Its most recent Spring 2016 rankings point to wide disparities in the quality of care among the nation’s hospitals. The quality indicators measured included hospital acquired infection rates, surgical mistakes, the adoption of safety measures, and patient communications. For example, how often did patients have bed sores or falls, how often did the hospital infect the patient, leave a foreign object in the patient during surgery, cause an air or gas bubble leading to a stroke, did the hospital, its nurses and doctors explain to the patient what to do for follow up care after discharge.
