Data on Physician Practices Now Available From AHRQ’s Comparative Health System Performance Initiative

A new data file added to AHRQ’s Compendium of U.S. Health Systems identifies 36,303 physician group practices and allows researchers, policymakers and others to assess how the practices are organized and owned according to the nation’s 626 health systems. The group practice data are publicly available so users can identify practices within health systems and then, linking to additional data sources, explore characteristics of the systems and their group practices, such as cost and quality of care. The compendium was developed by AHRQ’s Comparative Health System Performance Initiative, which studies how healthcare delivery systems promote evidence-based practices and patient-centered outcomes research in delivering care.
