Purpose of the Study
Restart a Heart (RSaHD) is an annual European day of action that aims to teach life-saving CPR skills to as many people as possible. In 2017, UK stakeholders collaborated to train over 195,000 young people in CPR. The event was organised by a partnership between the Resuscitation Council (UK), British Heart Foundation, British Red Cross, St John Ambulance and all UK ambulance services. In 2018 RSaHD is going global under the oversight of ILCOR (http://www.ilcor.org/wrah/). The aim of this study is to report details of the out-of-hospital cardiac arrests (OHCAs) that occurred on RSaHD 2017 in English NHS Ambulance Service Trusts.
Materials and Methods
Details of OHCAs that occurred on 16th October 2017 were obtained from the OHCA Outcomes (OHCAO) registry at University of Warwick.
Results
There were 48 OHCAs (68.8% male) attended by EMS from 5 ambulance services (Age: mean=65.4y; median=71y; crude incidence: 0.14/100,000). About 69% occurred in the home. 41.7% cases were bystander witnessed and 52.1% not witnessed. In witnessed OHCAs, 55.0% received bystander CPR (BCPR); only 1 case had a PAD applied and shock delivered. In not witnessed cases, 64% received BCPR (PAD used in 1 case). In both groups 5 cases achieved ROSC at hospital handover, only 2 and 3 cases had received BCPR, respectively. 1 case in each group survived to hospital discharge, both received BCPR.
We estimate that on RSaHD, there were about 78 cases in England (UK=92), of which about 16 (UK=19) cases achieved ROSC at hospital handover and 3 (UK=4) survived to discharge.
Conclusions
This crude analysis estimated that on Restart a Heart Day in 2016 about 76 lives were lost to cardiac arrest in England (90 in UK). The OHCAO will enable us to monitor the impact of RSaHD on outcomes after OHCA in the UK.
