Since 2016, HRiA has been contracted by CT Department of Public Health (DPH) to facilitate a planning process with a diverse, statewide stakeholder group known as the Population Health Council. HRiA is supporting the Council’s efforts to research, design, and pilot a model for Prevention Service Centers (PSCs) in three demonstration sites in the state, selected based on population density, availability of service providers, and health disparities. The project is one of three co-related initiatives of the CT State Innovation Model (SIM) grant. The SIM goal is to develop a plan to advance multi-payer health care payment and delivery system reform models while achieving better quality of care, lower costs, and improved health for the population. HRiA engaged in research to inform the planning activities: 1) An environmental scan to identify promising national and local models for community health integration and accountable communities for health; 2) A statewide capacity assessment to identify and catalogue community service providers; and 3) Focus groups with CBOs and public health entities to learn more about collaboration with health care entities, capacity to enter into accountable arrangements, data and information technology systems, and supports and resources needed. Findings were used to inform next steps for the PSC model including the development of a request for proposal for vendors to provide TA to Community Service Providers.
