The patient population of the present study consisted of 702 poisoning cases treated at the outpatient emergency clinic (EC) and 251 poisoning cases treated at the intensive care unit (ICU). The most common diagnosis of the EC’s patients in psychiatric hospital care was alchoholism and that of the ICU’s patients was psychosis or neurosis. In order to reduce cases of relapse of self poisoning patients, the larger general hospitals should have psychiatric clinics providing psychiatric treatment.
