Duration of Hospitalization and Post Discharge Suicide

Abstract

A retrospective cohort of discharged patients from all public psychiatric hospitals in Hong Kong (1997-1999) was linked to suicide data from Coroner's court. Patients hospitalized shorter than 15 days had significantly lower suicide rates than longer stay patients. The results were fairly consistent across immediate/late post discharge periods, gender, age, diagnoses, and narrow/wide definitions of suicide. This finding was opposite of what has been reported in the literature. Short hospitalization carried different suicide risks in different service settings.
