The frequency of depressive illness was investigated in 195 patients who had been referred consecutively after attempted suicide during the period 15. February 1989-15, October 1989. A total of 130 of these patients were admitted to hospital while the remainder were treated in the psychiatric emergency room or admission department. Registration of depressive symptoms on admission revealed that 85% had depressed mood and other depressive symptoms. According to the criteria established by Feighner et al. 51% suffered from definite depressive disease on admission. According to Zung's Depression Scale, 60% were depressed. On the basis of observations during hospitalization, 25% suffered from depressive disease according to the criteria established by Feighner et al. 19% of these patients suffered from endogenic depression according to the Newcastle I scale which corresponds to 5% of all the hospitalized patients with attempted suicide. Approximately 10% were treated with antidepressives. Only 8% were discharged with the diagnoses of endogenic or reactive psychoses (ICD-8). It is concluded that depressive symptoms occur in the majority of patients with attempted suicide but that slight non-endogenic depressive states are most commonly concerned and that many of these improve rapidly during hospitalization without medicinal treatment. Restraint should be observed in prescription of antidepressive medicine to patients with attempted suicide until the diagnosis of depressive disease is verified.
