Sudden cardiac arrest (SCA) is the leading cause of death in young athletes. Despite efforts to improve preparedness for cardiac emergencies, the incidence of out-of-hospital cardiac arrests in athletes remains high, and bystander awareness and readiness for SCA support are inadequate. Initiatives such as designing an emergency action plan (EAP) and mandating training in cardiopulmonary resuscitation (CPR) and automated external defibrillator use (AED) for team members and personnel can contribute to improved survival rates in SCA cases. This review provides an overview of SCA in athletes, focusing on identifying populations at the highest risk and evaluating the effectiveness of different screening practices in detecting conditions that may lead to SCA. This study summarizes current practices and recommendations for improving the response to SCA events, and highlights the need for ongoing efforts to optimize preparedness through the implementation of EAPs and the training of individuals in CPR and AED use. Additionally, it proposes a call to action to increase awareness and training in EAP development, CPR, and AED use for team members and personnel. To improve outcomes of SCA cases in athletes, it is crucial to enhance bystander awareness and preparedness for cardiac emergencies. Implementing EAPs and providing training in CPR and AED use for team members and personnel are essential steps toward improving survival rates in SCA cases.

Sudden cardiac arrest (SCA) during sports events has a dramatic impact on stadium-goers and the public and is often associated with poor outcomes unless treated with an automated external defibrillator (AED). Despite this, stadiums vary in AED use. This review aims to identify the risks and incidences of SCA, and the use of AEDs in soccer and basketball stadiums. A narrative review of all relevant papers was conducted. Athletes across all sports face an SCA risk of 1:50,000 athlete-years, with the greatest risk of SCA in young male athletes (1:35,000 person-years) and black male athletes (1:18,000 person-years). Africa and South America have the poorest soccer SCA outcomes at 3% and 4% survival. AED use on-site improves survival greater than defibrillation by emergency services. Many stadiums do not have AEDs implemented into medical plans and the AEDs are often unrecognizable or are obstructed. Therefore, AEDs should be used on-site, use clear signaling, have certified trained personnel, and be incorporated into stadiums’ medical plans.

In recent years, several actions have been made to shorten the chain of survival in out-of-hospital cardiac arrest (OHCA). These include placing defibrillators in public places, training first responders, and providing dispatcher-assisted CPR (DA-CPR). In this study, they aimed to evaluate the impact of these changes on patients’ outcomes, including achieving return of spontaneous circulation (ROSC), survival to discharge, and survival with favorable neurological function.

The Impact of Prehospital and Hospital Care on Clinical Outcomes in Out-of-Hospital Cardiac Arrest – PubMed (nih.gov)

Early defibrillation is a major determinant of survival in out-of-hospital cardiac arrest (OHCA). Shockable rhythms account for 18.7% of treated OHCA patients in emergency medical services (EMS), thanks to automated external defibrillators (AED). Shockable rhythms are strongly associated with improved survival rates compared to non-shockable rhythms in OHCA.

 

Defibrillation within 3–5 min of collapse can lead to survival rates as high as 50–70%.

 

Thus, reduced time between call to the emergency call centre (ECC) and AED using is a major issue.

 

Early recognition of OHCA and resuscitation performance with early defibrillation is the best way to increase survival chances. However, professional EMS arrive on site in about ten minutes in France.

 

The two steps to improve survival are one, to have volunteer rescuers on site quickly and two, to have them perform early defibrillation by an AED.

For the first step, notifying citizens as first responders to an OHCA event through a smartphone application with a mobile positioning system or a text message alert system increases early defibrillation and thereby improves survival.

 

The smartphone application SAUVLife© (Paris, France) currently used in France allows the ECC to solicit trained and registered lay rescuers. If you are connected and present in a one-kilometre perimeter around the victim, the application will alert and guide you to start CPR. It also warns another available lay-rescuer to a referenced AED and guides him to the victim.

 

In May 2022, a partnership between the EMS of the Angers University Hospital, the city of Angers, France and the SAUVLife© application was allowed to equip volunteer citizen rescuers with their own portable AED. These “super lay-rescuers” can be municipal staff, medical students or volunteers who agreed to always keep the defibrillator with them, day, and night. The geographical distribution of the portable AED in the 6 geographical districts of Angers resulted in homogeneous coverage of the city and rapid action regardless of the location of the OHCA.

 

With this innovative method, which is a first in France, aiming to increase AED usage before arrival of professional rescuers and to improve OHCA survival. This experiment should also allow to recruit more standard lay-rescuers and if successful, be extended to other areas.

Aims: Little is known about automated external defibrillator (AED) functionality in real-life settings. This study aimed to assess the functionality of all registered AEDs in a geographically selected area and calculate the proportion of historical out-of-hospital cardiac arrests (OHCAs) covered by non-functioning AEDs.

Methods: In this cross-sectional study they inspected all registered and available AEDs on the island of Bornholm in Denmark. There was information collected on battery status (determined by AED self-test) and electrode status, as well as AED availability. All historical OHCAs registered with the Danish Cardiac Arrest Registry on Bornholm during 2016-2019 were identified and then the proportion of OHCAs covered by an AED was calculated (regardless of functionality status) within ≤100, ≤750, and ≤1800 meters and the proportion of OHCAs covered by non-functioning AEDs.

Conclusion: Almost one-fifth of all registered and publicly available AEDs were not functional, primarily due to expired electrodes, failed self-tests or obstacles to retrieving AEDs. One in twenty historical OHCA was covered by a non-functional AED. Although general AED functionality was high, this finding underlines the importance of regular AED maintenance.

Out-of-hospital cardiac arrest is a global public health issue experienced by approximately 3.8 million people annually. Only 8% to 12% of these people survive to hospital discharge. Early defibrillation of shockable rhythms is associated with improved survival but ensuring timely access to defibrillators has been a significant challenge.

To date, the development of public-access defibrillation programs, involving the deployment of automated external defibrillators into the public space, has been the main strategy to address this challenge. Public-access defibrillator programs have been associated with improved outcomes for out-of-hospital cardiac arrest; however, the devices are used in <3% of episodes of out-of-hospital cardiac arrest. This scientific statement was commissioned by the International Liaison Committee on Resuscitation with 3 objectives:

(1) identify known barriers to public-access defibrillator use and early defibrillation,

(2) discuss established and novel strategies to address those barriers, and

(3) identify high-priority knowledge gaps for future research to address.

The writing group undertook systematic searches of the literature to inform this statement. Innovative strategies were identified that relate to enhanced public outreach, behaviour change approaches, optimisation of static public-access defibrillator deployment and housing, evolved automated external defibrillator technology and functionality, improved integration of public-access defibrillation with existing emergency dispatch protocols, and exploration of novel automated external defibrillator delivery vectors.

This study provides evidence- and consensus-based policy suggestions to enhance public-access defibrillation and guidance for future research in this area.

Aim: This study aimed to understand current community PAD placement strategies and identify factors which influence PAD placement decision-making in the United Kingdom (UK).

Methods: Individuals, groups and organisations involved in PAD placement in the UK were invited to participate in an online survey collecting demographic information, facilitators and barriers to community PAD placement and information used to decide where a PAD is installed in their experiences. Survey responses were analysed through descriptive statistical analysis and thematic analysis.

Results: There were 106 included responses. Distance from another PAD (66%) and availability of a power source (63%) were most frequently used when respondents are deciding where best to install a PAD and historical occurrence of cardiac arrest (29%) was used the least. Three main themes were identified influencing PAD placement: (i) the relationship between the community and PADs emphasising community engagement to create buy-in; (ii) practical barriers and facilitators to PAD placement including securing consent, powering the cabinet, accessibility, security, funding, and guardianship; and (iii) ‘risk assessment’ methods to estimate the need for PADs including areas of high footfall, population density and type, areas experiencing health inequalities, areas with delayed ambulance response and current PAD provision.

Conclusion: Decision-makers want to install PADs in locations that maximise impact and benefit to the community, but this can be constrained by numerous social and infrastructural factors. The best location to install a PAD depends on local context; work is required to determine how to overcome barriers to optimal community PAD placement.
