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.

成人自杀和自杀未遂：在精神病急诊室就诊 24 个月后探索自杀风险

目标：应在联系卫生服务后的短时间内测量自杀风险（包括企图自杀和自杀完成）。本研究的目的是确定精神科急诊科就诊后 24 个月内企图自杀和完成自杀的模式，并调查预测性风险因素，包括社会人口统计学和临床​​变量、既往自杀行为和服务利用。方法：在一家综合医院的精神病急诊室招募的便利样本 (n=147)，包括有自杀意念、自杀计划或先前有自杀企图的患者。这些患者被跟踪了 24 个月，重点关注两个主要结果：企图自杀和完成自杀。结果：六个月后没有完成自杀和 36 次自杀未遂，而在 24 个月后，有 7 人完成自杀，69 人企图自杀。24 个月时自杀未遂的最终逻辑回归模型将躯体病理和既往精神病住院次数确定为预测因素，受试者操作特征曲线下面积良好。结论：研究结果显示，随着时间的推移，自杀未遂和完成自杀的模式不同，表明在精神病急诊室进行系统的多学科自杀风险评估的重要性。
