Homeless patients tend to have greater psychiatric needs when presenting to the emergency department^.

Homeless patients tend to visit Emergency Departments (EDs) more frequently than the non-homeless population. The goal of this study was to assess differences in chief complaint, medical conditions, and disposition between homeless patients compared to non-homeless patients presenting to an urban ED.

This was a retrospective cohort of homeless patients ages ≥18 years compared to non-homeless controls from January 1, 2017 to December 31, 2017. Exclusion criteria were as follows: direct admission to hospital floor, repeat visits, or leaving without being seen. The primary endpoint of this study was to assess differences in chief complaint of homeless versus non-homeless patients upon presentation to the ED. Our secondary endpoints included differences in ED utilization between the two groups, in terms of length of stay, ambulance use, diagnosis, and disposition.

Homeless patients were more likely present to the ED for a psychiatric evaluation (homeless group 34% vs. non-homeless group 4%, p < 0.01) and have a history of a psychiatric diagnosis (56% vs. 10%, p < 0.01) compared to non-homeless controls. Homeless patients also tended to require more ambulance transport (46% vs. 16%, p < 0.01). More homeless patients were transferred to a psychiatric facility (40% vs. 1%, p < 0.01), while the majority of non-homeless patients were discharged home (50% vs. 93%, p < 0.01).

This study found that homeless patients had a significantly higher association with psychiatric diagnoses and greater ED utilization than non-homeless. This suggests the importance of increased access to consistent psychiatric care and follow up within the homeless population.
