Determinants of suicidal ideation and suicide attempt among former and currently homeless individuals.

Suicidal ideation and suicide attempt among currently or recently homeless individuals were both strongly associated with clinical variables. Based on the study results, specific interventions may be promoted to improve screening of homeless individuals with suicidal behavior and prevent hospitalization such as training programs and brief care management interventions, addiction liaison nurses, improved access to primary or specialized ambulatory services, and further development of case management and outreach programs for homeless individuals, especially those with functional disabilities.
