“…Although some of these values were for the particular case of witnessed OHCA and shockable rhythm, the overall survival rates for EVapp implementation of 12-30% for witnessed OHCA are very plausible, considering that overall survival rates of 20-50% have been observed or projected in other recent civilian-based systems [13,28,29,38,63]. Other mobile phone applications to mobilize volunteers to OHCA victims have been reported or are in development [25][26][27][28][29]64]. Most data is available for the country of The Netherlands and the capital of Stockholm [26,28,65].…”

“…Vercammen and Moens Cost Eff Resour Alloc (2020) 18:52 The current fraction of bCPR in Belgium for witnessed OHCA was estimated at 33%. Based on recent initiatives to mobilize volunteers via mobile phone application [25,26,28,47], responses of bCPR and bCPR + AED were assumed as 50 and 25%, respectively for the scenario of EVapp implementation.…”

“…Although 'bystander CPR' is defined, in scenarios that included community-response systems, firefighters and/or police personnel, the percentage of agreement that 'bystander CPR' had been performed ranged from 16-91% [24]. Nevertheless, previous civilian-based resuscitation initiatives, activating volunteers via a mobile phone application [25][26][27][28][29], have underscored the importance of increased rates of early BLS and/or use of public AED, even achieving survival to discharge rates of 40-50% [28].…”

Background EVapp (Emergency Volunteer Application) is a Belgian smartphone application that mobilizes volunteers to perform cardiopulmonary resuscitation (CPR) and defibrillation with publicly available automatic external defibrillators (AED) after an emergency call for suspected out of hospital cardiac arrest (OHCA). The aim is to bridge the time before the arrival of the emergency services. Methods An accessible model was developed, using literature data, to simulate survival and cost-effectiveness of nation-wide EVapp implementation. Initial validation was performed using field data from a first pilot study of EVapp implementation in a city in Flanders, covering 2.5 years of implementation. Results Simulation of nation-wide EVapp implementation resulted in an additional yearly 910 QALY gained over the current baseline case scenario (worst case 632; best case 3204). The cost per QALY associated with EVapp implementation was comparable to the baseline scenario, i.e., 17 vs 18 k€ QALY−1. Conclusions EVapp implementation was associated with a positive balance on amount of QALY gained and cost of QALY. This was a consequence of both the lower healthcare costs for patients with good neurological outcome and the more efficient use of yet available resources, which did not outweigh the costs of operation.

“…To bridge the time until EMS arrival, various systems worldwide introduced deployment of Community First Responders (CFR) to out-of-hospital cardiac arrests (OHCA) (4)(5)(6)(7)(8)(9)(10)(11)(12)(13). This led to an increased rate of CPR performed before arrival of the EMS (14,15). The spectrum of volunteers deployed is ranging from lay persons without medical background to highly trained medical professionals (4,6,7,11,16,17,12,13,18).…”

Background: Over the past decade Smartphone-based activation (SBA) of Community First Responders (CFR) to out-of-hospital cardiac arrests (OHCA) has gained much attention and popularity throughout Europe. Various programmes have been established, and interestingly there are considerable differences in technology, responder spectrum and the degree of integration into the prehospital emergency services. It is unclear whether these dissimilarities affect outcome. This consensus paper reviews the current state in Europe, reveals similarities and controversies, and aims to help aligning future strategies for SBA of CFR in Europe.Methods: In a consensus conference a three-step approach was used: (i) presentation of current research from five European countries; (ii) workshops discussing evidence amongst the audience to generate consensus statements; (iii) anonymous real-time voting applying the modified RAND-UCLA methodology to adopt or reject the statements. The consensus panel aimed to represent all stakeholders involved in this topic.Results: While 21 of 25 generated statements gained approval, consensus was only found for 5 of them. One statement was rejected but without consensus. Members of the consensus conference confirmed that CFR save lives. They further acknowledged the crucial role of emergency medical control centres and called for nationwide strategies. Conclusions: Smartphone-based alert of CFR to OHCA saves lives. The statement generated by the consensus conference help to advise the public, healthcare services and governments to utilise these systems to their full potential, and direct the research community towards fields that still need to be addressed.

“…Moreover, obesity and hypertension are risk factors for morbidity and mortality associated with COVID-19, which should add impetus to control these factors. A potential 21st century solution to low rates of bystander CPR and AED use may be the use of smartphone applications to send volunteer bystanders to sites of OHCA and to retrieve the nearest AED to enhance CPR and AED use ( 20 ).…”
