The ACG® System has been used in commercial and research settings worldwide, longer and more extensively than any other system on the market today. The software component is tried and true, continuously undergoing improvements and modifications in response to user needs.
The ACG System continues to evolve through research and development conducted at the Johns Hopkins Bloomberg School of Public Health, a world renowned institution. Over the past 30 years, the ACG System has been maintained and supported by dedicated Johns Hopkins faculty and staff in medicine, biostatistics, and health economics. Johns Hopkins University also offers support services by academic professionals to ensure appropriate implementation of the ACG System as well as accurate interpretation of the results.
The ACG System benefits from extensive global validation and testing. The ACG System Bibliography contains close to 1,000 published articles and reports from around the globe demonstrating its robustness in varying health care system contexts.
The ACG System facilitates the identification of multi-morbid patients with complex needs to enable timely care interventions. Available to all ACG System users, Guided Care® is a program designed to help primary care practices meet the complex needs of patients with multiple chronic conditions, where case mix is combined to support patient management.
Characterized by excellence in both research and practice, The ACG System Team has been creating risk measurement and case mix categorization methodology for more than 30 years, continuously refining and updating the system. Our team has virtually “written the book” on risk adjustment through numerous contributions in the published literature.
Johns Hopkins University Distinguished Professor Barbara Starfield, M.D., M.P.H., was recognized world-wide as an expert in primary care, case mix methodologies, and promotion of equity in health. Her defining work with patterns of morbidity forms the basis of the ACG System, which she co-developed.
When Prof. Starfield passed away in 2011, the Johns Hopkins Bloomberg School of Public Health established the Barbara Starfield Scholarship Fund to support doctoral students who pursue study and research that continue Dr. Starfield’s primary areas of focus. In continuing to honor her legacy, the ACG System Team instituted The Starfield Award.
Johns Hopkins University was founded on the principle that by pursuing big ideas and sharing what we learn, we make the world a better place. For more than 140 years, the university hasn’t strayed from that vision.
More than 21,000 undergraduate and graduate students are enrolled in the university’s nine schools.
For 36 years in a row, the university has put more money into research than any other U.S. academic institution.
36 Hopkins researchers past and present have earned Nobel Prizes.
The university reaches into nearly every corner of the globe, conducting research, training, and related activities in more than 150 countries.
