Abstract

BACKGROUND: Research is required to identify those psychiatric interventions with a protective effect against suicide. The overarching aim of the current study was to examine whether completed suicide in psychiatric patients in a Swedish population was associated with the quantity and nature of previous medical and psychosocial treatment interventions.

METHODS: This retrospective case-control study (n = 308) compared a group of deceased psychiatric patients with matched controls. For every case of suicide, a control was found within psychiatry that matched according to sex, age, and primary psychiatric diagnosis. A stepwise forward logistic regression model with suicide as the dependent outcome variable was used.

RESULTS: Receiving pharmacotherapy combined with psychotherapy [OR: 0.44 (95% CI: 0.226-0.876), p = 0.019] and a higher number of outpatient visits in psychiatry [OR: 0.99 (95% CI: 0.982-0.999), p = 0.028] were negatively associated with suicide. These associations were still significant after controlling for previous serious suicide attempts and somatic comorbidity.

CONCLUSIONS: Frequent visits and pharmacotherapy combined with psychotherapy seem to be important for preventing suicide in psychiatric patients. The reasons for not receiving such therapy are important issues for further study.
