Bystanders play a significant role in the immediate management of life-threatening hemorrhage. The Stop the Bleed (STB) program was designed to train lay rescuers (LRs) to identify and control life-threatening bleeding. The aim of this study was to evaluate the efficacy of STB training for rescuers from different backgrounds. We hypothesized that STB training would be appropriate to increase skills and knowledge of bleeding control techniques for all providers, regardless of level of medical training.
Course participants anonymously self-reported confidence in six major areas. A five-point Likert scale was used to quantitate participant's self-reported performance. Results were stratified into medical rescuers (MR) and LRs. Students' ability to perform STB skills were objectively assessed using an internally validated 15-point objective assessment tool. Data were pooled and analyzed using Student's t-test and chi-Squared test with P < 0.05 considered significant. Results are presented as average with standard deviation (SD) unless otherwise stated.
A total of 1974 participants were included in the study. Precourse confidence was lowest for both groups in management of active severe bleeding and ability to pack a bleeding wound. Postcourse confidence improved significantly for both groups in all 6 core areas measured (P < 0.001). The most significant increases were reported in the two previous areas of lowest precourse confidence-management of active severe bleeding-LRs 2.0 (SD 1.2) versus 4.2 (SD 0.9) and MRs 2.6 (SD 1.4) versus 4.6 (SD 0.6), P < 0.001-and ability to pack a bleeding wound-LR 2.1 (SD 1.3) versus 4.4 (SD 0.8) and MR 2.7 (SD 1.3) versus 4.7 (SD 0.05), P < 0.001. Objective assessment of LR skills at the end of the course demonstrated combined 99.3% proficiency on postcourse objective assessments.
This study provides quantitative evidence that Stop the Bleed training is effective, with both LRs and MRs demonstrating improved confidence and skill proficiency after a 1-h course. Future program development should focus on building a pool of instructors, continued training of LRs, and determining how often skills should be recertified.
旁观者在处理危及生命的大出血方面发挥着重要作用。“停止出血(STB)”计划旨在培训急救员识别和控制危及生命的出血。本研究旨在评估不同背景下的急救员接受 STB 培训的效果。我们假设 STB 培训将适合提高所有提供者的出血控制技术技能和知识,无论医疗培训水平如何。
课程参与者匿名自我报告在六个主要领域的信心。采用五点李克特量表对参与者自我报告的表现进行定量。结果分为医疗救援人员(MR)和急救员(LR)。使用内部验证的 15 分客观评估工具客观评估学生执行 STB 技能的能力。数据汇总并使用学生 t 检验和卡方检验进行分析,P 值<0.05 为有统计学意义。结果以平均值和标准差(SD)表示,除非另有说明。
共有 1974 名参与者纳入研究。课前两组对管理活动性严重出血和填塞出血伤口的能力最缺乏信心。课后两组在所有 6 个核心领域的信心均显著提高(P<0.001)。报告的最大增长出现在课前信心最低的两个领域,即管理活动性严重出血-LR 2.0(SD 1.2)与 4.2(SD 0.9),MR 2.6(SD 1.4)与 4.6(SD 0.6),P<0.001-和填塞出血伤口的能力-LR 2.1(SD 1.3)与 4.4(SD 0.8)和 MR 2.7(SD 1.3)与 4.7(SD 0.05),P<0.001。课程结束时对 LR 技能的客观评估显示,课后客观评估的综合合格率为 99.3%。
本研究提供了定量证据,表明 STB 培训是有效的,LR 和 MR 均在 1 小时课程后表现出信心和技能熟练程度的提高。未来的项目发展应侧重于建立教师队伍、继续培训 LR 以及确定技能应多久重新认证一次。
