Health-Related Social Needs and Health Care Access and Use by Payer Type.

BACKGROUND: While payers and health systems are increasingly interested in addressing health-related social needs (HRSNs) to reduce health care use and align with value-based care incentives and regulatory requirements, limited evidence enables actionable strategies to manage and address social needs across population groups. OBJECTIVES: To understand the relationship between HRSNs and health care access and use for adults with Medicare, Medicaid, and private health insurance coverage. RESEARCH DESIGN: Survey data from adult participants from the All of Us Research Program (2017-2023; n=126,490) and logistic regression were used to examine the association between food insecurity and housing instability and having a usual source of care, seeing a health care provider, and forgoing care due to cost-stratified by payer type. RESULTS: The prevalence of HRSNs varied substantially by insurance: food insecurity affected 49.20% of Medicaid beneficiaries 18-64 years of age, 11.89% of privately insured adults 18-64 years of age, and 5.20% of Medicare beneficiaries 65 years of age and older; housing instability affected 54.61%, 25.18%, and 14.99%, respectively. Food insecurity was associated with lower odds of having a usual source of care for Medicaid and privately insured adults, lower odds of use for privately insured adults, and higher odds of forgone care for all 3 payer types. Housing instability was associated with lower odds of having a usual source of care for all 3 papers and with higher odds of forgone care for all groups. CONCLUSIONS: HRSNs like food insecurity and housing instability vary substantially by payer type and influence health care access and utilization in different ways. This can inform the design of payer-specific health management strategies that incorporate HRSNs.
