Self‐Poisoning with Follow‐Up Considerations

One hundred patients who in 1963 had attempted self-poisoning and were subsequently admitted to the intoxication ward of a psychiatric hospital were studied twice: immediately after the attempted self-poisoning and 8 years after the attempt. It was found that within the follow-up period a total of nine patients had died, four of whom had committed suicide. The risk of suicide per years is .5%. According to the literature the range of the annual suicide risk is .9% to 2.5%.
