ObjectivesThe authors examined the clinical characteristics of homeless patients presenting to emergency departments (EDs) in the United States, with a focus on unintentional and intentional injury events and related comorbid conditions.MethodsThe study included a nationally representative sample of patients presenting to EDs with data obtained from the 2007 through 2010 National Hospital Ambulatory Medical Care Survey (NHAMCS). Descriptive and analytical epidemiologic analyses were employed to examine injuries among homeless patients.ResultsHomeless persons made 603,000 visits annually to EDs, 55% of which were for injuries, with the majority related to unintentional (52%) and self-inflicted (23%) injuries. Multivariate logistic regression analyses revealed that homeless patients had a higher odds of presenting with injuries related to unintentional (odds ratio [OR]=1.4. 95% confidence interval [CI]=1.1 to 1.9), self-inflicted (OR=6.0, 95% CI=3.7 to 9.5), and assault (OR=3.0, 95% CI=1.5 to 5.9) injuries.ConclusionsA better understanding of the injuries affecting homeless populations may provide medical and public health professionals insight into more effective ways to intervene and limit further morbidity and mortality related to specific injury outcomes.© 2014 by the Society for Academic Emergency Medicine.
