Timely and effective bystander first aid can improve outcomes for trauma victims. Bystanders are present at most traumas and are more likely to assist with prior training.
An evidence-based course was created for the general public in high-risk Chicago neighborhoods focused on basic traumatic first aid, including scene management, hemorrhage control, and mitigating the psychological impact of trauma to overcome the bystander effect. Prospectively, participants completed knowledge-based and self-efficacy assessments precourse, postcourse, and 6 mo follow-up. The change in self-efficacy and knowledge scores was analyzed.
Over 32 courses, 503 participants were taught; 474 and 460 participants completed precourse and postcourse surveys, respectively, whereas 60 of 327 who consented for follow-up completed the 6-mo survey. Postcourse, participants were more likely to assist trauma victims and felt more confident in the quality of care they could provide; the effect remained significant at 6 mo (all P < 0.001). All seven self-efficacy empowerment-based questions individually demonstrated improvement from precourse to postcourse (P < 0.001), with an overall mean (SD) increase of 2.8 (2.1, P < 0.001); six maintained significance at follow-up with an overall mean increase of 2.8 (1.9, P < 0.001). Knowledge scores improved from 6.2 of 10 to 7.2 postcourse and 7.7 at follow-up (P < 0.001). Most improved were the ability to render first aid and apply tourniquets.
The TFRC increased self-efficacy, successfully teaching initial trauma care, particularly hemorrhage control and scene safety, suggesting that a grassroots approach to trauma care may improve outcomes in communities that experience high violence rates.
及时有效的旁观者急救可以改善创伤患者的预后。大多数创伤都有旁观者在场,并且他们更有可能在接受过预先培训的情况下提供帮助。
为高风险芝加哥社区的普通民众创建了一门基于证据的课程,重点是基本的创伤急救,包括现场管理、控制出血和减轻创伤对旁观者的心理影响,以克服旁观者效应。前瞻性地,参与者在课前、课后和 6 个月随访时完成基于知识和自我效能的评估。分析自我效能和知识评分的变化。
在 32 门课程中,共教授了 503 名参与者;474 名和 460 名参与者分别完成了课前和课后调查,而在 327 名同意随访的参与者中,有 60 名完成了 6 个月的随访调查。课后,参与者更有可能协助创伤受害者,并对他们能够提供的护理质量更有信心;这种效果在 6 个月时仍然显著(均 P<0.001)。七个基于自我效能的赋能问题单独从课前到课后都有所改善(P<0.001),总体平均(SD)增加 2.8(2.1,P<0.001);六个在随访时仍具有统计学意义,总体平均增加 2.8(1.9,P<0.001)。知识得分从课前的 6.2 分提高到课后的 7.2 分和随访时的 7.7 分(P<0.001)。最显著的改善是提供急救和使用止血带的能力。
创伤现场急救课程提高了自我效能,成功教授了初步创伤急救,特别是控制出血和现场安全,这表明在高暴力率社区开展创伤急救基层方法可能会改善预后。
