A comparison of suicides in psychiatric in-patients, after discharge and in not recently hospitalized individuals.

OBJECTIVE:Time of in-patient treatment and the first weeks after hospital discharge have repeatedly been described as periods of increased suicide risk. This study compared demographic, clinical and suicide related factors between in-patient, post-discharge and not recently hospitalized suicides. METHODS:Suicide data from the Tyrol Suicide Register were linked with registers of three psychiatric hospitals in the state of Tyrol, Austria. Suicide cases then were categorized as in-patient suicides, post-discharge suicides (suicide within 12weeks after discharge) or never/not within 12weeks before death hospitalized suicides. Data were collected between 2004 and 2011. RESULTS:Of the total of 711 cases, 30 were in-patient, 89 post-discharge and 592 not recently hospitalized suicides. The three groups differed with regard to male-to-female ratio (lower in both hospitalized groups), marital status, suicide method used (jumping in in-patients, hanging in not recently hospitalized suicides), history of attempted suicide and suicide threats (highest in in-patients) and whether suicides had been in psychiatric or general practitioner treatment shortly before death. In most variables with significant differences there was a gradual increase/decrease with post-discharge suicides taking the middle place between the two other groups. CONCLUSIONS:The three suicide populations differed in a number of variables. Varying factors appear to influence suicide risk and choice of method differently in in-patient, post-discharge and not hospitalized suicides.
