Suicidal behavior in psychiatric emergency room patients

BACKGROUND: Psychiatric emergency room (ER) patients are thought to be at increased risk of suicide. The prevalence and characteristics of suicidal behavior in a recent sample of patients who came to the ER for psychiatric evaluation were examined. METHODS: Charts of 311 consecutive psychiatric ER patients were reviewed. Suicidal behavior was considered present if current suicidal ideation or attempts within 24 hours of or during the emergency evaluation were noted in the chart. RESULTS: Suicidal behavior was present in 38% of the psychiatric ER patients. Younger age, white race, affective disorders in female patients, and substance abuse disorders in male patients were features of the suicidal group. Sex of the patient was not associated with suicidal behavior. CONCLUSIONS: Suicidal behavior is prevalent in the psychiatric ER. Effective suicide prevention in this setting will hinge on finding more specific risk factors.
