INTRODUCTION
Uncontrolled bleeding is a leading cause of preventable death. The "Stop the Bleed" (StB) program trains laypersons in hemorrhage control. This study evaluated the efficacy of video-based StB training.
METHODS
Participants watched two different videos: a didactic video (DdV) and a technical video (TeV) demonstrating proper techniques for StB skills (i.e., direct pressure [DP], wound packing [WP], and tourniquet application [TA]). Then, they completed a standardized skills examination (SE). Participants were surveyed at three different time points (baseline, post-DdV, and post-SE) for comparison. We compared paired categorical and continuous variables with the McNemar-Bowker test and Wilcoxon signed-rank test, respectively. Alpha was set at 0.05.
RESULTS
One hundred six participants were enrolled: 52% were female and the median age was 23 y (22, 24). At baseline, 29%, 8%, and 13% reported being somewhat or extremely confident with DP, WP, and TA, respectively. These percentages increased to 92%, 79%, and 76%, respectively, after the DdV (all, P < 0.0001). After the TeV and SE, percentages increased further to 100%, 96%, and 100% (all, P < 0.0001). During the SE, 96%, 99%, and 89% of participants were able to perform DP, WP, and TA without prompting. Among participants, 98% agreed that the video course was effective and 79% agreed that the DdV and TeV were engaging.
CONCLUSIONS
We describe a novel paradigm of video-based StB learning combined with an in-person, standardized SE. Confidence scores in performing the three crucial StB tasks increased significantly during and after course completion. Through remote learning, StB could be disseminated more widely.
简介
出血失控是可预防死亡的主要原因。“停止出血”（StB）计划培训非专业人员进行出血控制。本研究评估了基于视频的 StB 培训的效果。
方法
参与者观看了两个不同的视频：一个是教学视频（DdV），一个是技术视频（TeV），演示了 StB 技能的正确技术（即直接压迫[DP]、伤口填塞[WP]和止血带应用[TA]）。然后，他们完成了标准化技能考试（SE）。参与者在三个不同的时间点（基线、DdV 后和 SE 后）进行调查以进行比较。我们使用 McNemar-Bowker 检验和 Wilcoxon 符号秩检验分别比较配对的分类变量和连续变量。α 值设定为 0.05。
结果
共纳入 106 名参与者：女性占 52%，中位年龄为 23 岁（22，24）。基线时，分别有 29%、8%和 13%的参与者对 DP、WP 和 TA 有一定程度或非常有信心。在观看 DdV 后，这些百分比分别增加到 92%、79%和 76%（均 P<0.0001）。在观看 TeV 和 SE 后，百分比进一步增加至 100%、96%和 100%（均 P<0.0001）。在 SE 期间，96%、99%和 89%的参与者无需提示即可进行 DP、WP 和 TA。在参与者中，98%的人认为视频课程有效，79%的人认为 DdV 和 TeV 引人入胜。
结论
我们描述了一种新的基于视频的 StB 学习模式，结合了现场标准化 SE。在课程完成期间和之后，执行三个关键 StB 任务的信心评分显着提高。通过远程学习，可以更广泛地传播 StB。
