Suicide and suicide attempts in adults: exploring suicide risk 24 months after a psychiatric emergency room visit

Objective: Suicide risk (including attempted and completed suicide) should be measured over short periods of time after contacting health services. The objective of this study was to identify the patterns of attempted and completed suicides within 24-months of a psychiatric emergency department visit, as well as to investigate predictive risk factors, including sociodemographic and clinical variables, previous suicidal behavior, and service utilization. Method: A convenience sample (n=147), recruited at a general hospital's psychiatric emergency room, included patients with suicidal ideation, suicidal plans or previous suicide attempts. These patients were followed for 24 months, focusing on two main outcomes: attempted and completed suicides. Results: After six months there were no completed suicides and 36 suicide attempts, while after 24 months there were seven completed suicides and 69 suicide attempts. A final logistic regression model for suicide attempts at 24 months identified somatic pathology and the number of previous psychiatric hospitalizations as predictive factors, with a good area under the receiver operating characteristic curve. Conclusions: The findings showed distinct patterns of attempted and completed suicides over time, indicating the importance of a systematic multidisciplinary suicide risk evaluation in psychiatric emergency rooms.

Comparison of Clinical Characteristics between Single and Repeated Suicide Attempters Admitted to Emergency Room / 신경정신의학

OBJECTIVES: This study compares single and repeat suicide attempts, and evaluates the risk factors associated with suicide re-attempts. METHODS: Two hundred and seventy-nine patients admitted to emergency rooms in four university hospitals in Daegu after suicide attempt were included in this study (n=179 single suicide attempters, n=100 repeated attempters). A structured interview focused on demographic, clinical, suicidal and psychological characteristics was administered to these patients after recovery from physical and psychological impairments. RESULTS: Individuals with repeated suicide attempts were younger, more highly educated, had more history of psychiatric treatments, took more psychiatric medications, and had more sustained suicidal ideations, bipolar disorders and personality disorders than individuals with single suicide attempt. Individuals with repeated suicide attempts marked significantly higher scores in the Childhood Trauma Questionnaire, Patient Health Questionnaire-9, and the Barratt Impulsiveness Scale. Multivariate logistic regression showed that below the sixties, history of psychiatric treatments, personality disorders, substance use disorders and sustained suicidal ideations were significantly associated with predictive factors for subsequent suicide attempt. CONCLUSION: Our findings suggest that repeat suicide attempters have different clinical characteristics from single suicide attempters, and some risk factors raise the risk of further suicide attempts. It is necessary for suicidal prevention program planners to be aware of these risk factors, especially for first-time suicide attempters.
