The Leapfrog Group has named the nation's top hospitals for 2011, and the list shines a spotlight on how health IT can help improve patient care—even preventing medical errors that can lead to adverse drug reactions and deaths. Leapfrog bases its annual ranking on a survey of hospitals' processes, quality of care, and patient safety. Its evaluation includes "stringent IT requirements," said Leah Binder, Leapfrog CEO.
