ObjectiveTo investigate potential risk factors associated with the repetition of deliberate self-poisoning (DSP).MethodsRetrospective medical record review of all patients who presented to the emergency department of a tertiary teaching hospital after DSP between January 1, 2000, and December 31, 2009. Repetition of a suicide attempt was determined from reported episodes before the index episode or from 2 visits to the same hospital during the study period. Demographic information, clinical variables, and other variables at the first suicide attempt were investigated for factors associated with repetition of DSP.ResultsOf the 967 patients, 203 (21%) presented with repeated suicide attempts. Patients with repeat suicide attempts differed in sex, occupation, living condition, method of DSP, history of psychiatric treatment, reversibility, and psychiatric diagnosis. In the multivariate regression analysis, the only reliable associated factors for repeat suicide attempt were sex (P = .001), living condition (P < .001), method of DSP (P < .036), and history of psychiatric treatment (P < .001).ConclusionEarly psychological intervention and close observation is required for patients who are female, living without a family, use antidepressants, and have a history of psychiatric treatment.Crown Copyright © 2011.
