Research demonstrates that improving population health and achieving health equity will require broad approaches that address social, economic, and environmental factors that influence health. Recently there has been increased recognition of the importance of these factors to health. Moreover, the ACA includes provisions to help bridge health care and community health. Reflecting the increased focus and new opportunities provided under the ACA, a growing number of initiatives are emerging at the national, state, and local level to address broader determinants of health. Given Medicaid’s longstanding role serving a diverse population with complex health, behavioral, and social needs, efforts to address social determinants of health are emerging through many Medicaid delivery and payment initiatives. This brief provides an overview of the broad factors that influence health and describes emerging efforts to address them, including initiatives within Medicaid.
