Suicides, mental health care and interdisciplinary specialised addiction services in the Agder counties 2004-13

Most of those who commit suicide suffer from one or more mental disorders. We wished to identify the proportion that had been in contact with mental health care or interdisciplinary specialised addiction services during their lifetime and in the year prior to their death, and to describe characteristics of these patients.

Information on suicides in the Agder counties in the years 2004–2013 was retrieved from the Cause of Death Registry. Patient records from Sørlandet Hospital were reviewed with the aid of a structured form.

Altogether 329 suicides were included in the study. Of these, 66.6 % had at some point in life been in contact with mental health care or interdisciplinary specialised addiction services, 46.2 % during the year preceding their suicide. Altogether 28.6 % were actively undergoing treatment. The proportion who had been in contact in the preceding year tended to be lower among patients younger than 20 when compared to other age groups. Among those who had completed their treatment, there were more patients with adaptation disorder than in the group that remained in treatment; among those who remained in treatment there were more patients with psychotic disorders than among those who had completed their treatment.

A higher proportion of those who committed suicide in the Agder counties were in contact with mental health care and interdisciplinary specialised addiction services than what has been found in equivalent international studies. The findings underscore the need to develop effective measures to prevent suicides in these groups of patients.
