Bystander CPR rates have steadily increased in England between 2014 and 2018. In West Yorkshire, there have been two important developments during this time. We aimed to describe whether postcode districts (PCDs) with more cumulative annual 'Restart a Heart' (RSAH) and/or Community First Responder (CFR) scheme activity between 2014 and 2018 were associated with greater improvements in non-EMS bystander CPR rates for out-of-hospital cardiac arrest (OHCA) when compared with PCDs in the same region with lesser or no such historic activity during the same time period.
We collated data from the OHCA Outcomes Registry for all non-EMS witnessed OHCA in West Yorkshire treated by Yorkshire Ambulance Service. We analysed clusters of PCDs with high and low levels of RSAH and CFR activity between 2014 and 2018 using descriptive statistics, and comparisons were made between groups using chi-square and t-test.
The reported bystander CPR rate for non-EMS witnessed OHCA cases for West Yorkshire rose from 38.4% in 2014 to 69.7% in 2018. The largest increases were seen in PCDs with high RSAH activity (+34.3%) and in the combination of high RSAH and low CFR activity (+38.5%). There was no significant difference when considering the interaction between RSAH and CFR groups.
The data infers the possibility of a non-significant association between improved non-EMS bystander CPR rates and RSAH training and CFR scheme activity. We recommend coordinated mass training, in particular for children in regions where CPR is not a mandatory part of the school curriculum.
2014年至2018年间，英国旁观者实施心肺复苏术（CPR）的比例稳步上升。在此期间，西约克郡有两项重要进展。我们旨在描述，与同一地区在2014年至2018年期间累积年度“重启心脏”（RSAH）和/或社区第一反应者（CFR）计划活动较少或没有此类历史活动的邮政编码区（PCD）相比，2014年至2018年期间累积年度“重启心脏”（RSAH）和/或社区第一反应者（CFR）计划活动较多的邮政编码区（PCD）是否与院外心脏骤停（OHCA）的非紧急医疗服务旁观者CPR比例的更大改善相关。
我们整理了约克郡救护车服务机构治疗的西约克郡所有非紧急医疗服务目击OHCA的OHCA结果登记数据。我们使用描述性统计分析了2014年至2018年期间RSAH和CFR活动水平高和低的PCD集群，并使用卡方检验和t检验对组间进行了比较。
西约克郡非紧急医疗服务目击OHCA病例的报告旁观者CPR比例从2014年的38.4%上升到2018年的69.7%。RSAH活动高的PCD（+34.3%）以及RSAH活动高和CFR活动低的组合（+38.5%）增幅最大。考虑RSAH和CFR组之间的相互作用时，没有显著差异。
数据推断非紧急医疗服务旁观者CPR比例的改善与RSAH培训和CFR计划活动之间可能存在不显著的关联。我们建议进行协调的大规模培训，特别是在CPR不是学校课程必修部分的地区对儿童进行培训。
