In collaboration with Human Services Research Institute (HSRI), Desert Vista Consulting recently evaluated the Minnesota PIN program, a managed care organization (MCO)/county partnership involving Medica Health Plan, Dakota County, and Medica Behavioral Health. A key component of the PIN program model involves a Patient Navigator model that provides case management and coordination of physical and mental health care and social services for individuals with serious mental illness. The evaluation will assess the effectiveness of the PIN program in addressing access, quality and cost issues and will identify the components of the Navigation Model that are most successful and may be refined and replicated.
