[Risk factors for inpatient suicide].

OBJECTIVE: The study aimed to examine suicidal behaviour during in-patient care in a psychiatric university hospital.
METHOD: Based upon a psychiatric basic documentation system prevalence and risk factors of in-patient suicides and suicide attempts were investigated (1995 - 2010).
RESULTS: A total of 42 in-patient suicides and 166 attempts were found among 16 251 patients. According to the multivariate logistic regression analysis the risk of suicide during hospitalization increases significantly for male patients, with more previous psychiatric hospitalizations and suicidality according to clinical impression at admission or suicide attempt before admission. Patients with affective or schizophrenic disorders were at highest risk. The following risk factors are associated with suicide attempt during stay: female gender, borderline personality disorder (F60.3), more previous psychiatric hospitalizations, shorter duration of disorder, earlier age of onset, suicidality according to clinical impression at admission or suicide attempt before admission.
CONCLUSION: As depressive and schizophrenic patients represent the high-risk group of in-patient suicide, suicide prevention should be a major goal in their treatment. More frequent suicide risk assessment is recommended particularly before granting a leave or an outing. © Georg Thieme Verlag KG Stuttgart · New York.
