A study was made of the results of treatment of 57 patients who made 68 suicide attempts by means of burns in the period between 1979 and 1987. They formed 14 per cent of the total patient population older than 16 years of age. Attempted suicide was observed most frequently in patients between 20 and 39 years of age. The sex incidence was equal. Most patients were in contact with or had been in contact with mental health care institutions at the time of their attempt, half of the attempts took place in a psychiatric hospital. Twelve patients died, in nine the prognosis was considered to be so poor that in view of the seriousness of the burns or the accompanying injuries no treatment was initiated. Follow-up took place after an average 3.8 years (1-8.25 years). Information was obtained on all 45 surviving patients. Eight patients had died, six of natural causes and two had committed suicide. Eighteen patients were living at home, 13 were residents at a psychiatric hospital, three were living in a protective commune, two were being detained during Her Majesty's pleasure and one was in prison. It appeared to be difficult to incorporate these patients in a closed follow-up regimen.
