The objectives of this study were to perform a systematic review and meta-analysis of studies reporting prevalence of personality disorders (PDs) in emergency departments (EDs) and evaluate the effect of comorbid PDs on clinical outcomes. A systematic search of five databases along with manual searching and expert consultation was performed. A quality appraisal was conducted. A total of 29 articles were included. Prevalence of PDs in ED attendees varied depending on presenting complaint, Q(4) = 577.5, p < .01, with meta-analytic prevalence rates of suicide and self-harm at 35% and 22%, respectively. The assessment method had a significant effect on prevalence rates, Q(3) = 17.36, p < .01. Comorbid PD was a risk factor for repeating presenting complaint, subsequent ED return, and hospitalization. Better identification of PDs using screening tools in EDs could improve patient management and clinical outcomes. Future research should focus on PD prevalence in unselected ED populations using validated diagnostic interviews.

对急诊科中的人格障碍患病率和患者结果进行系统回顾和荟萃分析。

这项研究的目的是对报告急诊室（ED）人格障碍（PD）患病率的研究进行系统的回顾和荟萃分析，并评估合并症PD对临床结果的影响。进行了五个数据库的系统搜索以及手动搜索和专家咨询。进行了质量评估。总共包括29篇文章。ED参与者中PD的患病率根据提出的投诉而有所不同，Q（4）= 577.5，p <.01，自杀和自我伤害的荟萃分析患病率分别为35％和22％。评估方法对患病率有显着影响，Q（3）= 17.36，p <.01。合并PD病是重复提出投诉，随后的ED返回和住院的危险因素。使用急诊室中的筛查工具更好地鉴定PD可改善患者管理和临床结果。未来的研究应使用经过验证的诊断性访谈，重点关注未选择的ED人群的PD患病率。
