BackgroundThe social determinants of health are economic and social conditions that contribute to health. Access to housing is a major social determinant of health and homeless patients often rely on emergency departments (EDs) for their healthcare. These patients are frequently discharged back to the street which further perpetuates the cycle of homelessness and negatively affects their health. Previous work has described the financial and systems implications of ED-housed interventions for homeless patients; this review summarizes ED-based interventions that seek to improve the social determinants of health of homeless patients.MethodsWe conducted a search of multiple databases and gray literature for studies investigating interventions for homelessness that were initiated in the ED. Studies had to use a control group or use a pre/post-intervention design and measure outcomes that demonstrate an effect on health or the social determinants of health.ResultsThirteen studies were identified that met the inclusion criteria. Two studies were housing first interventions and were effective in providing housing and improving health. Seven studies used variations of case management and were able to address many of the social needs of people who are homeless.ConclusionThis review demonstrated that ED interventions can be effective in improving the social determinants of health of homeless individuals and can be the place to initiate housing interventions. ED providers must advocate for the resources necessary to properly address the social needs of this marginalized population. Equipped with the proper resources, EDs can be one place where the cycle of homelessness is broken.
