Diabetes is becoming an epidemic within the general population. The risk of developing diabetes is estimated to be twice that for people with serious mental illness (SMI) or intellectual disability (ID). Simultaneously, persons with SMI or ID typically receive fewer primary care services for chronic disease management. This situation is more challenging for those populations living in rural areas with reduced access to care. This project was designed to address these concerns by providing training on the mental health and medical aspects of diabetes to providers in both primary care and behavioral health to increase competency, treatment coordination, and outcome effectiveness for both disciplines. Results included increased primary care visits, attention to the whole person, and use of monitored HEDIS assessments for diabetes.
