Public safety personnel (PSP) and frontline healthcare professionals (FHP) are frequently exposed to potentially psychologically traumatic events (PPTEs), and report increased rates of post-traumatic stress injuries (PTSIs). Despite widespread implementation and repeated calls for research, effectiveness evidence for organizational post-exposure PTSI mitigation services remains lacking. The current systematic review synthesized and appraised recent (2008–December 2019) empirical research from 22 electronic databases following a population–intervention–comparison–outcome framework. Eligible studies investigated the effectiveness of organizational peer support and crisis-focused psychological interventions designed to mitigate PTSIs among PSP, FHP, and other PPTE-exposed workers. The review included 14 eligible studies (n = 18,849 participants) that were synthesized with qualitative narrative analyses. The absence of pre–post-evaluations and the use of inconsistent outcome measures precluded quantitative meta-analysis. Thematic services included diverse programming for critical incident stress debriefing, critical incident stress management, peer support, psychological first aid, and trauma risk management. Designs included randomized control trials, retrospective cohort studies, and cross-sectional studies. Outcome measures included PPTE impacts, absenteeism, substance use, suicide rates, psychiatric symptoms, risk assessments, stigma, and global assessments of functioning. Quality assessment indicated limited strength of evidence and failures to control for pre-existing PTSIs, which would significantly bias program effectiveness evaluations for reducing PTSIs post-PPTE.

旨在减轻公共安全和一线医护人员创伤后应激损伤的同伴支持和以危机为重点的心理干预：系统评价

公共安全人员（PSP）和一线医疗保健专业人员（FHP）经常暴露于潜在的心理创伤事件（PPTE），并报告创伤后应激损伤（PTSI）的发生率增加。尽管广泛的实施和反复的研究呼吁，但仍缺乏组织暴露后PTSI缓解服务的有效性证据。当前的系统评价是按照人口－干预－比较－结果框架，对来自22个电子数据库的最新研究（2008年至2019年12月）进行综合和评估。合格的研究调查了组织同伴支持和针对危机的心理干预措施的有效性，这些干预措施旨在减轻PSP，FHP和其他PPTE暴露工人中的PTSI。该评价包括14项符合条件的研究（n = 18,849名参与者），通过定性叙事分析进行了综合。缺乏前评估后和结果测量方法不一致的情况，无法进行定量荟萃分析。主题服务包括针对严重事件压力汇报，严重事件压力管理，同伴支持，心理急救和创伤风险管理的各种编程。设计包括随机对照试验，回顾性队列研究和横断面研究。结果指标包括PPTE的影响，旷工，药物使用，自杀率，精神病症状，风险评估，耻辱感和整体功能评估。质量评估表明，证据强度有限，无法控制现有的PTSI，
