Prescribing housing: A scoping review of health system efforts to address housing as a social determinant of health

US health systems have begun to address housing instability within a larger effort to address social determinants of health. To explore existing themes within efforts by health systems to reduce housing instability and improve health, the authors conducted a scoping review supplemented with key informant interviews. Twenty-two articles were analyzed and 7 participants from 6 health systems were interviewed. Themes identified from the literature and interviews included intervention strategies and funding, access, coordination, and administrative processes and evaluation. As more health systems integrate housing-related interventions, findings from this study highlight the need for more upstream focus, consistent funding, and reliable evaluation strategies.
