The Leapfrog Group is a consortium of private and public employers who collectively purchase health care for more than 30 million Americans. Leapfrog recommends four evidence-based practices for implementation by hospitals: computerized provider order entry, intensivist coverage of critically ill patients, evidence-based hospital referral for high-risk patients, and adoption of the National Quality Forum's safe practices. This study found that hospitals that reported implementing at least one patient safety practice also provided slightly better care for myocardial infarction and congestive heart failure (as measured by publicly reported quality data), but not for pneumonia. The authors note that as the Leapfrog recommended practices are not directly tied to improving care quality for these specific conditions, implementation of Leapfrog patient safety practices likely indicates an overall commitment to providing higher-quality care.
