[High mortality from both natural and unnatural causes. A 10-year follow-up of patients admitted to a center for poisoning treatment after attempted suicide].
While it is well known that suicide rates for suicide attempters are high, mortality rates for all causes needed to be more thoroughly investigated. A Danish 10-year follow-up study of patients who in 1980 were admitted to a poisoning treatment centre after attempted suicide was carried out with the purpose of describing mortality by suicide and other causes of death, and to identify predictive factors. A total of 974 patients aged 15 and over referred to a poisoning treatment centre after deliberate self-poisoning were included in the study. Death by different causes registered in the Danish Death Cause Register was the outcome measure. Over a 10-year follow-up period 306 patients had died; 103 by suicide, 131 from natural causes, 31 by accidents, five were murdered and in 36 cases the cause of death was uncertain. The Standard Mortality Rate (SMR) was 550. The cause-specific SMRs were for suicide 2960, for natural causes 236, for accidents 1256 and for uncertain causes 5459. In Cox-regression analysis high-risk factors for later suicide were more than one previous suicide attempt (relative risk (RR) 2.25), living alone (RR 2.28) and age (RR 1.03 per year). Predictors of death by natural causes were pension (RR 1.69), drug abuse (RR 2.72), more than one previous suicide attempt (RR 2.25), age (RR 1.06 per year) and male sex (RR 2.49). The group of patients fulfilling at least one high-risk criteria for later suicide differed significantly from the rest of the patient group regarding frequency of suicide, but both sensitivity and specificity remain low.(ABSTRACT TRUNCATED AT 250 WORDS)
