Background: Outreach psychiatric emergency services play an important role in all stages of a suicidal crisis; however, empirical assessment data are scarce. This study describes characteristics of patients assessed by these services and involved in suicidal crises. Method: During a 5-year period, detailed information from psychiatric emergency service assessments was recorded; 14,705 assessments were included. Characteristics of patients with/without suicidal behavior and with/without suicide attempts were compared. Outcomes were adjusted for clustering of features within individual patients. Results: Suicidal behavior was assessed in 32.2% of patients, of whom 9.2% attempted suicide. Suicidal behavior was most commonly associated with depression or adjustment disorder and these patients were referred to the service by a general practitioner or a general hospital, whereas those who attempted suicide were less likely to be referred by a general practitioner. Those who attempted suicide were more likely to be female and have had a referral by a general hospital. Self-poisoning by medication was the most common method of attempting suicide. Limitations: Bias could be due to missed or incomplete assessments. Primary diagnoses were based on clinical observation at the time of the assessment or on the primary diagnosis previously recorded. In addition, suicidal behavior or attempted suicide might have been underestimated. Conclusions: Suicidal behavior is commonplace in assessments by psychiatric emergency services. Suicidal patients with/without a suicide attempt differed with respect to demographic features, primary diagnoses, and referring entities, but not with respect to treatment policy. About 40% of the suicidal patients with/without an attempt were admitted following assessment.

外展精神科紧急服务。

背景：外展精神科急诊服务在自杀危机的各个阶段都发挥着重要作用；然而，经验评估数据很少。本研究描述了通过这些服务进行评估并涉及自杀危机的患者的特征。方法：在 5 年期间，记录了精神科急诊服务评估的详细信息；包括 14,705 项评估。比较了有/没有自杀行为和有/没有自杀企图的患者的特征。结果根据个体患者内的特征聚类进行了调整。结果： 32.2% 的患者接受了自杀行为评估，其中 9.2% 的患者企图自杀。自杀行为最常与抑郁症或适应障碍相关，这些患者被全科医生或综合医院转诊到服务机构，而那些企图自杀的人被全科医生转诊的可能性较小。那些企图自杀的人更有可能是女性，并且被综合医院转诊。通过药物自我中毒是最常见的企图自杀的方法。局限性：偏差可能是由于错过或不完整的评估。主要诊断基于评估时的临床观察或先前记录的主要诊断。此外，自杀行为或企图自杀可能被低估了。结论：自杀行为在精神科急诊服务评估中很常见。有/没有自杀企图的自杀患者在人口统计学特征、主要诊断和参考实体方面存在差异，但在治疗政策方面没有差异。大约 40% 有/没有企图自杀的患者在评估后被录取。
