Objective
Homeless adults make extensive use of emergency department (ED) services. This study examined factors associated with moderate and high ED use in a cohort of chronically homeless individuals.
Methods
A cross-sectional analysis identified factors related to ED use in a cohort of 755 individuals at 11 sites at entry into in the Collaborative Initiative to Help End Chronic Homelessness (CICH). Bivariate analyses identified sociodemographic, housing status, health status, and service-related factors associated with moderate and high ED use. Independent risk factors were then identified using a multivariate multinomial model. Hierarchical regression was used to compare the strengths of association between ED use and blocks of factors composed of sociodemographic, housing, health, and service-related characteristics.
Results
In a 3-month period, 30% of participants visited the ED 1 or 2 times (moderate ED use) and 12% used the ED 3 or more times (high-ED use). ED use was most strongly associated with poor health status and utilization of other non-ED services, and to a lesser extent with housing status.
Conclusions
Increased ED utilization was associated with both medical and psychiatric morbidity and greater use of non-ED services. ED use is thus related to high need and acuity and is not ameliorated by use of other services. Housing instability and homelessness contribute less robustly to increased ED use. More coordinated services may better address the complex medical, housing, and psychosocial needs of chronically homeless individuals.
