Impact of community initiatives on non-EMS bystander CPR rates in West Yorkshire between 2014 and 2018

AIM: 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. METHOD: 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. RESULTS: 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. CONCLUSION: 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.
