Abstract

Background

Bystander cardiopulmonary resuscitation (CPR) and defibrillation improve out-of-hospital cardiac arrest survival. However, basic life support (BLS) skills are low.

Aim

The FirstCPR cluster randomised controlled trial aimed to test the effectiveness of a community organisation-targeted BLS education and training approach.

Methods

Clusters (community organisations with 50+ members) were randomly allocated to intervention (12-month period of opportunities to access BLS education and training) or control (no intervention). Outcomes were assessed via surveys at 12 months and pre-specified analysis involved hierarchical mixed-models.

Results

Of 165 randomised clusters (82 intervention), 58% were sports and 42% were social/faith-based. Most of the intervention clusters (74/82) participated in at least one intervention activity (15 in all activities). Factors such as the COVID-19 pandemic and organisation support impacted intervention uptake. Overall 924 members, across 93 clusters (407 from 57 intervention clusters; 517 from 36 control clusters), completed surveys. At 12-months, intervention organisation surveyed members reported higher rates of: being trained and willing to perform CPR on a stranger (primary outcome: 63.8% vs 46.9 %; Adjusted Odds Ratio (AOR) 2.22, 95% confidence interval (CI):1.50–3.30), confidence to use an automated external defibrillator (AED) (48.4% vs 26.4%; AOR:3.23, 95%CI:2.22–4.71) and willingness to use AEDs on a stranger (73.9% vs 62.9%; AOR:1.84, 95%CI:1.22–2.80).

Conclusions

The results should be interpreted cautiously as the survey response rates were very low. However, survey respondents showed desired outcomes and key learnings for future research were gained.

FirstCPR：一项实用的基于社区组织的集群随机试验，旨在增加社区培训和准备，以应对院外心脏骤停

背景：旁观者心肺复苏（CPR）和除颤可提高院外心脏骤停患者的生存率。然而，基本生命维持（BLS）技能很低。目的：FirstCPR集群随机对照试验旨在测试以社区组织为目标的BLS教育和培训方法的有效性。方法分组（成员超过50人的社区组织）随机分为干预组（12个月有机会接受劳工统计局教育和培训）和对照组（不进行干预）。通过12个月的调查评估结果，预先指定的分析涉及分层混合模型。结果165个随机分组（82个干预组）中，58%为体育类，42%为社会/信仰类。大多数干预组（74/82）至少参加了一项干预活动（15人参加了所有活动）。COVID-19大流行和组织支持等因素影响了干预措施的采用。共有924名成员，横跨93个集群(407名来自57个干预集群；来自36个对照群集的517人)，完成了调查。在12个月时，接受干预组织调查的成员报告说，接受过培训并愿意对陌生人进行心肺复苏术的比例更高(主要结果：63.8%对46.9%；调整优势比（AOR） 2.22, 95%置信区间（CI）： 1.50-3.30)，使用自动体外除颤器（AED）的置信度(48.4% vs 26.4%；AOR:3.23, 95%CI: 2.22-4.71)和对陌生人使用aed的意愿(73.9% vs 62.9%；优势:1.84,95% ci: 1.22—-2.80)。结论调查回复率较低，对调查结果应谨慎解读。然而，调查对象显示了期望的结果，并获得了未来研究的关键知识。
