The San Luis Obispo County Behavioral Health Department (SLOBHD) is partnering with Community Health Centers of the Central Coast (CHC) and other health providers to provide health services at Behavioral Health sites to individuals with serious mental illness. The San Luis Obispo Health Integration Project (SLO-HIP) will provide a health home including medical exams, preventive screenings, health promotion and disease management and navigation services. A Peer Wellness Coach will assist participants and family members with navigation and facilitate access to services. SLO-HIP will provide medical services to at least 280 of its 2800 clients with serious mental illness in its first year, with increased goals 700, 1120 and 1400 clients in Years 2, 3 and 4, respectively. Project goals are to: 1) Improve integration of physical and behavioral health care by providing medical services on-site to SLOBHD patients through a partnership with CHC. 2) Reduce chronic disease among SLOBHD's adult, severely mentally ill patients through early detection, intervention, and prevention education. 3) Improve access to a full range of integrated health services by employing a peer wellness coach, with lived experience, to support SLO-HIP patients. 4) Enhance information sharing between providers through electronic health information exchange between diverse electronic health record systems. 5) Evaluate cost benefit of integrated physical and behavioral health care through data collection and performance management. 6) Develop a sustainable system of integration of services by identifying funding mechanisms and responsibilities. An Integrated Treatment Team, including project staff and health care providers, will meet weekly to case manage, collect data, address barriers and improve program quality. A Coordination Team composed of agency executives, financial officers, medical directors and others will oversee SLO-HIP's operations and evaluation, and develop sustainability plans.
