Medicaid investments to address social needs in Oregon and California

Health care organizations across the US are developing new approaches to addressing patients' social needs. Medicaid programs are uniquely placed to support these activities, given their central role in supporting low-income Americans. Yet little evidence is available to guide Medicaid initiatives in this area. We used qualitative methods to examine how Medicaid funding was used to support social interventions in sites involved in payment reforms in Oregon and California. Investments were made in direct services-including care coordination, housing services, food insecurity programs, and legal supports-as well as capacity-building programs for health care and community-based organizations. A mix of Medicaid funding sources was used to support these initiatives, including alternative models and savings. We identified several factors that influenced program implementation, including the local health system context and wider community factors. Our findings offer insights to health care leaders and policy makers as they develop new approaches to improving population health.
