An overwhelming proportion of road traffic deaths and injuries in low- and middle-income countries (LMICs) occur in prehospital environments. Lay first responders such as police officers play an important role in providing initial assistance to victims of road traffic injuries either alone or in collaboration with others. The present study evaluated a postcrash first aid (PFA) educational program developed for police officers in Tanzania. A 16-h PFA educational program was conducted in Dar es Salaam, Tanzania, for 135 police officers. Participants completed training surveys before, immediately and 6 months after the training (before, N = 135; immediately after, N = 135; after 6 months, N = 102). The primary outcome measures were PFA knowledge, perceived skills confidence, and skills utilization. Parametric and nonparametric tests were used to analyse changes in outcome. The mean PFA knowledge score increased from 44.73% before training (SD = 20.70) to 72.92% 6 months after training (SD = 18.12), p < .001, N = 102. The mean PFA perceived skills confidence score (measured on a 1–5 Likert scale) increased from 1.96 before training (SD = 0.74) to 3.78 6 months after training (SD = 0.70), p < .001, N = 102. Following training, application of the recovery position skill (n = 42, 46%) and application of the bleeding control skill (n = 45, 49%) were reported by nearly half of the responding officers. Less than a quarter of officers reported applying head and neck immobilization skills (n = 20, 22%) following training. A PFA educational program has shown to improve police officers’ knowledge and perceived skills confidence on provision of first aid. However qualitative research need to be conducted to shed more light regarding reasons for low utilization of trained first aid skills during follow-up.

事后急救教育计划对交警人员知识，感知技能的信心和技能使用的影响：单臂前后干预研究

在中低收入国家（LMIC），绝大多数的道路交通伤亡发生在院前环境中。诸如警察之类的急救人员在单独或与他人合作向道路交通伤害受害者提供初步援助方面发挥着重要作用。本研究评估了为坦桑尼亚警官开发的灾后急救（PFA）教育计划。在坦桑尼亚的达累斯萨拉姆进行了为时16小时的PFA教育计划，培训了135名警官。参与者在训练之前，之后和训练后6个月完成了训练调查（之前，N = 135；之后，N = 135；六个月后，N = 102）。主要结果指标是PFA知识，感知的技能自信心和技能使用率。使用参数和非参数测试来分析结果的变化。PFA的平均知识评分从训练前的44.73％（SD = 20.70）增加到训练后6个月（SD = 18.12）的72.92％，p <.001，N =102。PFA感知的技能置信度平均得分（按1 –5李克特量表）从训练前的1.96（SD = 0.74）增加到训练后6个月（SD = 0.70）的3.78，p <.001，N =102。训练后，应用恢复姿势技能（n = 42， 46％的人和出血控制技能的应用（n = 45，49％）被报告了将近一半的警官。不到四分之一的军官报告说在训练后应用了头颈部固定技能（n = 20，22％）。PFA教育计划已显示出可以提高警官对提供急救知识和技能的信心。但是，需要进行定性研究，以了解随访过程中未充分利用受过训练的急救技能的原因。
