2015 AcademyHealth HSR Impact Awardee: The ACG System


Jonathan Weiner, DrPH accepted the 2015 HSR Impact Award on behalf of the ACG System team during the AcademyHealth National Health Policy Conference in Washington, D.C.

The prestigious HSR Impact Award is presented annually to health services research that has made a clear impact on health policy and practice. This year’s winner, The Johns Hopkins ACG System, has gained international acceptance as a standard measurement tool and is applied on a daily basis in hundreds of diverse settings throughout the world for population needs assessment, capitation adjustment, chronic care management, predictive modeling, and provider performance profiling. This model, which examines data to study the relationship between patterns of morbidity and health care use, cost, and outcomes, built upon the work of the late Barbara Starfield and her colleagues Jonathan Weiner, Donald Steinwachs, and Christopher Forrest, expanding the earlier work on children to all age groups.
