Impact of hospital and health system initiatives to address social determinants of health (SDOH) in the United States: A scoping review of the peer-reviewed literature

BACKGROUND: Hospital and health system initiatives addressing Social Determinants of Health (SDOH) are essential for achieving whole-person care and advancing health equity. Building on prior research characterizing these efforts (Part 1), this scoping review (Part 2) evaluates the effectiveness of these initiatives, with a focus on SDOH data integration, EHR utilization, and the broader scope of hospital efforts in addressing individual- and system-level determinants of health. Using an integrated conceptual framework combining the DeVoe & Cottrell framework for operational assessment and the National Academy of Medicine (NAM) 5A framework for systemic evaluation, this study provides a multidimensional assessment of hospital-based SDOH interventions. 

METHODS: Guided by PRISMA-ScR criteria, this review analyzed 41 U.S.-based studies published between 2018 and 2023, identified through three academic databases. Eligible studies examined hospital initiatives addressing SDOH with measurable outcomes. Analyses assessed SDOH data collection, integration into care practices, EHR use, and overall initiative effectiveness. 

RESULTS: Most studies (66%) were randomized controlled trials in urban settings (68%), targeting patients with chronic or mental health conditions (39%) or high-risk healthcare users (20%). Nearly half of initiatives (49%) addressed multiple SDOH domains, focusing on Social & Community Context, Economic Stability, and Neighborhood & Built Environment. Only 24% of initiatives utilized EHRs for SDOH data collection. EHR-based initiatives demonstrated significantly higher adherence to evidence-based practices, including use of community resource guides for referrals (90% vs. 45%, p = 0.013). Across all outcome measures, 79% demonstrated improvement, with no instances of worsening outcomes. However, 85% of initiatives lacked community-level SDOH data integration, and few employed upstream, universal strategies. Process, clinical, and social outcomes were unevenly prioritized, with only 10% of studies addressing all three outcome types. 

CONCLUSIONS: While these initiatives reflect progress in integrating SDOH into care workflows and improving whole-person care at the individual level, progress toward health equity remains insufficient. Persistent gaps in EHR use, community-level data integration, and upstream strategies hinder systemic impact, potentially perpetuating disparities. Strengthening SDOH-EHR integration, fostering community partnerships, and supporting policy advocacy are critical to bridging individual and community needs. Future research should emphasize long-term, sustainable, and community-level impacts of hospital-led SDOH interventions.
