Improving Social Needs Intervention Research: Key Questions for Advancing the Field

Abstract

Spurred by accumulated evidence documenting how social determinants of health shape health outcomes as well as the push for better value, the healthcare sector is embracing interventions that address patients' health-related social needs. An increasing number of healthcare organizations and payers are experimenting with strategies to identify needs and connect patients to resources that address identified needs with the goal of improving health outcomes, reducing avoidable utilization of costly health services, and improving health equity. Although many studies link social factors to health, relatively little published research exists about how the healthcare sector can effectively intervene to help identify and address social needs. This paper summarizes emerging evidence and identifies key areas where more research is needed to advance implementation and policy development. Although some healthcare-based social needs interventions have been shown to improve health and reduce avoidable utilization, important gaps remain in terms of comparative effectiveness and cost effectiveness of social needs intervention approaches. Additionally, the field would benefit from an increased understanding of mechanisms of action to maximize practitioners' ability to tailor interventions. More research is also needed to guard against unintended consequences and ensure these interventions reduce health inequities. Finally, implementation science research should identify supports and incentives for adoption of effective interventions. Focusing both public and private research efforts on these evidence gaps can help advance identification of interventions that maximize both health equity and healthcare value.

Neighborhood socioeconomic deprivation is associated with worse patient and graft survival following pediatric liver transplantation

“…However, retransplantation is a major healthcare expenditure and preventing even 1 episode of graft failure may realize cost savings. While it remains to be seen whether such programs will be cost‐effective, there is a strong moral imperative—reiterated in Health People 2020—to ensuring equitable child health outcomes.…”

Healthcare Sector Activities to Identify and Intervene on Social Risk: An Introduction to the American Journal of Preventive Medicine Supplement

“…25−47 The second cluster of articles in this supplement highlights research on these social care interventions with the goal of informing the major investments being made in this area. Fichtenberg et al 48 from both Agency for Healthcare Quality and Research and the Center for Medicare and Medicaid Innovation present a foundational article on existing intervention evidence, emphasizing a critical need for higher-quality evidence both on what works and how to implement effective models in real-life practice settings. The evaluation of the Center's Accountable Health Communities demonstration project is designed to add to existing knowledge in both of those areas, though results are still several years away.…”

A qualitative investigation of lived experiences of long-term health condition management with people who are food insecure

“…Fundamentally there is an urgent need to rethink public policies that are driving up the numbers of people affected by poverty and food insecurity in the UK [27,[98][99][100]. Healthcare professionals can also play a role by recognising and supporting patients with chronic health problems, and resource needs, such as poverty and food insecurity [59,101,102].…”
