The Johns Hopkins ACG® (Adjusted Clinical Groups®) System has the distinction of being developed, tested and supported by a world-renowned academic and medical research institution, The Johns Hopkins University. The academic home of the ACG System allows for an unparalleled openness to the methods. Each component of the system is exposed to the user which allows the system to be easily adapted to unique local circumstances and applications. The ACG methodology is subject to continuous critical review and testing by a team of distinguished health services researchers led by Dr. Jonathan Weiner. This transparency and academic credibility is critical when trying to disseminate risk information to providers and purchasers of healthcare.
The Johns Hopkins Bloomberg School of Public Health has an unwavering commitment to the ongoing development of the ACG System and its dissemination to both private sector and government users. The Johns Hopkins University has a multi-disciplinary faculty that works to improve health and prevent disease and disability through the education of future public health leaders and through research on the causes and possible remedies of significant public health problems. Our goal is to promote equitable, effective and efficient health care around the globe. The ACG System is one strategic initiative to achieve that goal.
The ACG System offers a widely used and rigorous health-based risk adjustment approach. Used by healthcare providers, health plans, and public-sector agencies the ACG System has a uniquely clinical perspective on person health that emphasizes the inter-relationship of multiple diseases to explain healthcare utilization both retrospectively and prospectively. The ACG System has withstood the financial and clinical pressures of the healthcare marketplace to become a statistically valid and industry standard risk adjustment and predictive modeling method.
