The purpose of this study has been to describe the course over ten years and prognosis for a cohort of patients who had been admitted to a psychiatric department following a suicide attempt. The cohort consisted of 207 patients who had been admitted in the period 1.10.1980-20.4.1981 to a department of psychiatry following a suicide attempt. At the index attempt 99 patients were randomly selected and interviewed. Information on the remainder was obtained from psychiatric case histories, casualty records and discharge reports. Ten years after the index attempt information concerning death, date and cause was collected. Of the 207 patients involved, 52 (25.1%) were dead. Twenty-five (12.1%) had committed suicide, the remainder had died of natural, accidental or unknown causes. Relative to the general population the death rate from suicide and other causes was extremely high. Predictors of suicidal outcome were substance abuse and dangerous index attempt. At least one of these two predictors was present for 72% of those who committed suicide and for 43% of those who did not commit suicide. Aging and previous suicide attempts were the only significant predictors of other causes of death.
