Attempted suicide in Denmark. IV. A five-year follow-up.

From October 1, 1980 to April 20, 1981, 207 patients were admitted to the Department of Psychiatry, Odense University Hospital, after attempting suicide. Information on physical, mental and social conditions was collected. The patients were then followed for 5 years, to register subsequent suicidal behaviour and to try to identify relevant factors for evaluation of future suicide risk. During the follow-up period 11.6% of the attempters committed suicide, the majority within the first year after the index attempt. Seventy-five percent of the suicides were committed less than 6 months after the last contact with the psychiatric ward. Predictors for future suicide were chronic somatic disease, depression, abuse of medicine, and chronic alcohol abuse. The authors emphasize the need for a thorough medical evaluation of patients attempting suicide, to be able to identify and eventually treat these conditions.
