General hospital suicides--a psychological autopsy study in Finland

Although both severe medical disorders and mental disorders are established risk factors for suicide, it is not known if patients who commit suicide in general hospitals differ from others. This study investigated current mental disorders and other clinical characteristics among general hospital suicide victims and compared them with other suicide victims in an unselected nationwide population. Drawing on data from a psychological autopsy study of all suicides (N = 1397) in Finland during one year, all suicides committed by patients in a general hospital setting were identified. Retrospective DSM-III-R consensus diagnoses were assigned and general hospital suicide victims were compared with other suicide completers in terms of clinical characteristics. Twenty-six general hospital suicide victims, 1.9% of all suicides, were identified. Subjects who completed suicide during general hospital treatment were older and used more violent suicide methods than other suicide victims. One or more diagnoses of psychiatric (Axis I) disorders were assigned for 88% of the general hospital suicide victims. Overall, the most prevalent disorder was major depression, which was more common among the general hospital suicide victims, even when age was controlled for. The findings of this study suggest that most people who commit suicide during a spell of general hospital treatment suffer from current mental disorder, as do suicide victims in general. The recognition and treatment of major depression in particular should be improved in order to prevent suicide in general hospitals.
