Cost-Effectiveness of Social Determinants of Health Interventions: Evaluating Multisector Community Partnerships' Efforts.

INTRODUCTION

The purpose of this analysis was to rapidly evaluate the potential costs, cost-effectiveness, and long-term effects of efforts by multisector community partnerships (MCPs) to improve chronic disease outcomes and advance health equity by addressing social determinants of health (SDOH).

METHODS

In 2022, the evaluators partnered with 13 MCPs to collect data on start-up and ongoing costs for implementing SDOH interventions and on intervention reach and timing. In 2023, the team used the Prevention Impacts Simulation Model to estimate the longer-term impact of MCPs' efforts over 5-, 10-, and 20-year periods. The team also analyzed costs and cumulative 10- and 20-year cost-effectiveness of the MCPs' SDOH interventions.

RESULTS

Over 20 years, SDOH interventions implemented by the 13 MCPs can potentially prevent 970 premature deaths and avert $105 million in medical costs and $408 million in productivity losses. The 20-year cumulative results show potential net costs of $38,300 per quality-adjusted life-year gained from the healthcare sector perspective and indicate potentially reduced costs and improved health outcomes from the societal perspective.

CONCLUSIONS

These findings can help inform and provide support for future investments in SDOH interventions. With a better understanding of costs needed to start up and implement SDOH interventions, funders, and MCPs can prepare for the resources required to do this work. Findings also suggest promising long-term impacts and potential cost-effectiveness for most MCP-implemented SDOH interventions.
