NIH-PA Author ManuscriptMethods-Participants were linked to administrative databases to capture hospital admissions during the study period (2005)(2006)(2007)(2008)(2009). Logistic regression was used to identify predictors of medical/surgical and psychiatric hospitalizations.Results-Among 1,165 homeless adults, 20% had a medical/surgical hospitalization and 12% had a psychiatric hospitalization during the study period. These individuals contributed a total of 921 hospitalizations, of which 548 were medical/surgical and 373 were psychiatric. Independent predictors of medical/surgical hospitalization included birth in Canada, having a primary care provider, higher perceived external health locus of control, and lower health status. Independent predictors of psychiatric hospitalization included being a current smoker, having a recent mental health problem, and having a lower perceived internal health locus of control. Being accompanied by a partner or dependent children was protective for hospitalization.Conclusions-Health care need was a strong predictor of medical/surgical and psychiatric hospitalizations. Some hospitalizations among homeless adults are potentially avoidable, while others represent an unavoidable use of health services.
KeywordsHospitalization; Homeless persons; Health care utilization Homeless adults are frequent users of inpatient hospital services. In a nationally representative sample of homeless persons in the United States, almost one in four respondents reported being hospitalized in the past year, a rate four times higher than U.S. norms. 1 The frequent use of inpatient hospital services partially reflects the high prevalence of acute and chronic disease, injuries and assaults, and substance use and mental illness among this population. [1][2][3] However, the high rates of hospitalization have also been attributed to a lack of access to primary and preventative care, particularly in the United States where 50% of homeless people have no health insurance. 1,[4][5][6][7] In a nationally representative sample of persons who used homeless services in the United States, Kushel et al. show that lack of health insurance and African American race/ethnicity, as compared to non-Latino white race/ethnicity, were the only factors significantly associated with a lower odds of self-reported hospitalization 1 In a subsequent study, Kushel et al. show that being uninsured significantly decreased the likelihood of self-reporting a non-maternal hospitalization in the past year, while food instability and housing instabilit...
