Suicide among psychiatric patients in Fukuoka Prefecture]

To investigate suicide among psychiatric patients in Japan (mainly Fukuoka prefecture), a questionnaire survey was submitted to psychiatrists from departments of psychiatry of university hospitals in Japan, departments of psychiatry of Rosai Hospitals in Japan, psychiatric hospitals in Fukuoka prefecture, psychiatric clinics in Fukuoka prefecture, and departments of psychiatry of general hospitals in Fukuoka prefecture regarding their psychiatric patients who died from suicide (266 females and 267 males). A large proportion of the patients at completed suicide was aged within the thirties to fifties. The majority of patients suffered from either F3 (mood disorders) or F2 (schizophrenia, schizotypal and delusional disorders) categories of the ICD-10 classification. Approximately one-fifth of the patients in Fukuoka prefecture had jobs at the time of completed suicide. The main "occupational risk factors" that were found to be risks for suicide were "failure or overloaded responsibilities in their jobs" and "worsening business situation". The main "other risk factors", i.e., risk factors other than "occupational risk factors" were "worsening psychiatric conditions", "personal life events (e.g., somatic illness or marital discord)" and "life events in other family members (e.g., familial discord or familial problems)". Over 50% of all cases had both "occupational risk factors" and "other risk factors", suggestive of the necessity for multidimensional evaluation and care in the treatment of suicidal patients. Given that numerous males that suffer from psychiatric disorders commit suicide without seeing a psychiatrist, it is important to establish a system to treat them appropriately in order to prevent unnecessary deaths.
