Completed suicide in psychiatric inpatients and former inpatients. A comparative study.

A total of 49 psychiatric inpatient suicides were compared with 53 former psychiatric inpatients who had committed suicide within one year after their discharge. Significant differences were found in the diagnostic distribution of both groups, especially the predominance of schizophrenics among inpatient suicides, and of alcoholics and drug abusers among suicides of former inpatients. Furthermore, some other important differences between the groups emerged that bore practical implications. In different diagnostic groups suicide occurs for different reasons and based on different psychosocial backgrounds. In the investigation of suicide in psychiatric patients, homogeneity of the population studied in terms of patient status should be strived for.
