The Stewards of Change Institute (SOCI) has just released an important new Issue Brief titled “Interoperability Insights: Demonstrating the Need and the Benefits of Connecting Health and Human Services.” This SOCI Issue Brief uses the Integrated Care for Kids (InCK), an initiative funded by the Centers of Medicare and Medicaid Innovation (CMMI), to illustrate the far-broader need for interoperability and information-sharing across programs, systems, and domains. SOCI’s intent, with this paper and with Project Unify, is to provide practical guidance, tools, and models that can be leveraged, replicated, and improved over time to address the enormous and growing need for coordinated care across the nation.
