This case study highlights the success of a cross-specialty diabetes pilot program, implemented by Geisinger Health System (Geisinger), to help control type 2 diabetes amongst Keystone Accountable Care Organization (ACO) beneficiaries. Geisinger, a member of the Keystone ACO, began to implement the program in early 2019 across Geisinger primary care providers (PCP). Beneficiaries continue to see reductions in their A1C levels, and the program will expand to other chronic conditions and be rolled out to providers throughout the entire ACO network.

In June of 2019, the Geisinger Health Plan’s type 2 diabetes prevention program earned full recognition from the Centers for Disease Control and Prevention (CDC), making it one of only 20 program suppliers in Pennsylvania to do so. Full recognition status is reserved for programs that effectively deliver high-quality, evidence-based programming through maintaining participant retention and showing clinical outcomes that meet all the standards for CDC recognition. Using interviews with the Geisinger team, this case study details how Geisinger continued its success managing type 2 diabetes within its ACO population.
