HOMELESS VETERANS UTILIZATION OF MEDICAL, PSYCHIATRIC, AND SUBSTANCE-ABUSE SERVICES

This study focuses on the association between homeless veterans' prior utilization of medical, psychiatric, and substance abuse services and biopsychosocial characteristics reported at admission into a domicili ary care program. Given the large number of veterans in the US homeles s population and their health care needs, understanding factors associ ated with health service use among homeless veterans is significant. R esearch participants were 429 homeless male veterans who had been admi tted to the Domiciliary Care for Homeless Veterans Program site at the West Los Angeles Veterans Affairs Medical Center between February 198 8 and July 1992 for treatment of medical, psychiatric, or substance di sorders. Results of logistic regression analyses indicated that self-r eported need (chronic medical problems, serious psychiatric symptoms, combat stress, alcohol use) and evaluated need for care (evidence of l iver dysfunction) were important to veterans' use of health services i n the 6 months before program admission. Predisposing social structure factors (education, residential stability, and usual sleeping place) were also significant predictors of service utilization. Overall, need factors were more strongly related to service use. Supplementary logi stic regression analyses indicated that comorbidity of need factors de serves attention in understanding homeless veterans' use of services. In conclusion, it is important to attend to predisposing social struct ure factors as potential barriers to care for homeless veterans.
