Stop the Bleed (STB) is a national training program aiming to decrease the mortality associated with life-threatening bleeding due to injury. The purpose of this study was to evaluate the efficacy and confidence level of security personnel placing a tourniquet (TQ) compared to civilians.
Pre and post questionnaires were shared with security personnel (Group 1) and civilians (Group 2). Both groups were assessed to determine comfort level with TQ placement. Time and success rate for placement was recorded pre- and post-STB training. A generalized linear mixed model or generalized estimating equations was used to compare pre and post measurements.
There were 234 subjects enrolled. There was a statistically significant improvement between the pre- and post-training responses in both groups with respect to comfort level in placing a TQ. Participants also demonstrated increased familiarity with the anatomy and bleeding control after STB training. A higher successful TQ placement was obtained in both groups after STB training (Pre-training: Group 1 [17.4%], Group 2 [12.8%]; Post-training: Group 1 [94.8%], Group 2 [92.3%]). Both groups demonstrated improved time to TA placement with a longer mean time improvement achieved in Group 1. Although the time to TQ placement pre-and post-training was statistically significant, we found that the post-training times between Groups 1 and 2 were similar (P = .983).
Participants improved their confidence level with the use of hemorrhage control techniques and dramatically increased the rate and time to successful placement of a TQ. While civilians had the greatest increase in comfort level, the security personnel group saw the most significant reduction in the time to successful TQ placement. These findings highlight the critical role of STB in educating and empowering both civilians and security personnel in bleeding control techniques.
止血(STB)是一个全国性的培训项目,旨在降低因受伤导致的危及生命的大出血死亡率。本研究的目的是评估安保人员与平民相比使用止血带(TQ)的效果和信心水平。
向安保人员(第 1 组)和平民(第 2 组)发放了预-后调查问卷。两组都评估了他们对 TQ 放置的舒适度。在 STB 培训前后记录了放置 TQ 的时间和成功率。使用广义线性混合模型或广义估计方程比较了预-后测量值。
共纳入 234 名受试者。两组在 TQ 放置舒适度方面,培训前后的反应均有统计学意义的改善。参与者在接受 STB 培训后,对解剖学和出血控制的熟悉程度也有所提高。两组在 STB 培训后 TQ 放置成功率更高(培训前:第 1 组[17.4%],第 2 组[12.8%];培训后:第 1 组[94.8%],第 2 组[92.3%])。两组在接受 STB 培训后放置 TA 的时间都有所改善,第 1 组的平均时间改善更长。尽管 TQ 放置的预-后培训时间具有统计学意义,但我们发现第 1 组和第 2 组之间的后培训时间相似(P=0.983)。
参与者对使用出血控制技术的信心水平有所提高,显著提高了 TQ 放置的成功率和时间。虽然平民的舒适度提高幅度最大,但安保人员组在 TQ 成功放置的时间上的减少幅度最大。这些发现强调了 STB 在教育和授权平民和安保人员掌握出血控制技术方面的关键作用。
