Concurrent increases in evidence about social determinants of health and the use of value-based health care incentives are driving new efforts to integrate health care and human services. Despite expectations that the integration of these complementary services could improve health, reduce health inequities, and reduce potentially avoidable health care use and costs, current evidence on the effectiveness, implementation, and sustainability of such cross-sectoral partnerships is sparse and mixed. To realize the potential of health care and human services integration, knowledge gaps in these key areas must be filled. In doing so, particular attention needs to be paid to understanding how power and resource differentials between organizations in the two sectors influence integration approaches and their impacts. Furthermore, increased societal investments in resources to address social needs are likely necessary for integrative initiatives to yield desired individual- and population-level impacts.
