Lifesaving Impact of AED Programmes Across UK and Ireland

Automated External Defibrillator (AED) programmes are significantly enhancing survival rates for out-of-hospital cardiac arrests (OHCAs) across the UK and Ireland. With thousands of lives at stake each year, the strategic placement of AEDs and increased public awareness are proving vital in bridging the gap between collapse and critical intervention. [20]

Cardiac arrest remains a major public health challenge. In the UK, there are over 30,000 OHCAs annually where emergency medical services attempt resuscitation, yet fewer than 1 in 10 individuals survive. [16, 32, 40] Similarly, in Ireland, approximately 5,000 people suffer a sudden cardiac arrest each year. [42, 44] The critical factor in improving these odds is rapid intervention. For every minute that passes without cardiopulmonary resuscitation (CPR) and defibrillation, the chance of survival decreases by up to 10%. [40, 42] Early defibrillation, particularly within 3-5 minutes of collapse, can dramatically increase survival rates to as high as 50-75% in some circumstances. [10, 34]

Progress in the UK: Schemes and Statistics

The UK has seen a concerted effort to increase the availability of public access defibrillators (PADs). The British Heart Foundation (BHF) reports over 110,000 defibrillators registered on The Circuit, the national defibrillator network, with 58.6% of these accessible 24 hours a day, seven days a week. [16] This represents a substantial increase of 30,000 devices since September 2023. [15]

Government initiatives are also playing a crucial role. The Department for Education, for instance, advised in June 2025 that its defibrillator programme had provided over 20,000 devices to schools in England. [15] By July 2023, all state-funded schools in England that did not already have one had received a defibrillator. [8, 34] These efforts aim to ensure that more communities have access to these life-saving devices. The Resuscitation Council UK (RCUK) strongly advocates for widespread installation and public availability of defibrillators, emphasising that they can be used by anyone, regardless of prior training, thanks to clear spoken instructions and visual guides. [4, 13]

While overall survival rates for OHCAs in England remained around 8% in 2022, studies suggest that early defibrillation by bystanders significantly improves outcomes. [20] For patients defibrillated within 5 minutes, survival rates can reach 37.3%. [20] The focus is now on optimising AED placement and increasing public confidence in their use to further boost these figures. RCUK actively promotes registering defibrillators on The Circuit so that ambulance services can direct callers to the nearest device. [19, 32]

Despite the known benefits, AEDs are currently used in a minority of cases. In England, public access defibrillators were used in only 7.9% of OHCAs in 2024. [16] Research in the East of England found that while AEDs were available within 500m of a cardiac arrest in 79% of cases, they were only used in 10% of those incidents. [29, 33] This highlights a significant opportunity for improvement through enhanced awareness and accessibility. [20]

Ireland's Defibrillator Landscape and Survival Improvements

In Ireland, the importance of early defibrillation is equally recognised. The 2022 annual report from the Out-of-Hospital Cardiac Arrest Register (OHCAR) recorded 2,802 out-of-hospital cardiac arrests where resuscitation was attempted. Of these, 206 people (7.3%) survived to leave hospital. [14] However, where a member of the public delivered defibrillation before the ambulance arrived, the survival rate dramatically increased to 31%. [14] In 2023, the survival rate to hospital discharge for OHCAs in Ireland was 8.4%, a 1% rise translating to an extra 34 lives saved. [28]

While there is no legal requirement for workplaces in Ireland to have an AED, the Health and Safety Authority (HSA) advises that it is good practice to consider their provision, especially where a first aid responder is present. [38, 45] The HSA's updated Guidelines on First-Aid at Places of Work now include information on the use and maintenance of AEDs. [36] Furthermore, anyone in Ireland can use an AED, and the Civil Liability Act 2011 protects those who assist in emergencies. [38]

Peer-reviewed analysis of the Irish OHCA registry between 2012 and 2020 found that bystander defibrillation was associated with a 78% increase in the adjusted odds of survival to hospital discharge. [14] The highest survival rate (30%) was among patients who received defibrillation from bystanders, though these cases accounted for only 6.8% of all patients treated. [41] Urban locations in Ireland also show a 40% higher chance of survival compared to rural settings. [41]

Challenges and the Path Forward

While the new AED installation programmes are a significant step forward, challenges remain. A lack of awareness regarding AED locations and, crucially, public confidence in using them, continues to be a barrier. [30] Resuscitation Council UK recommends that all school children are taught CPR and how to use an AED, and that everyone who is able should learn CPR. [11] They also suggest defibrillators should be available in places with large numbers of people, increased risk of cardiac arrest, or where emergency services access may be delayed. [11]

Ultimately, the continued expansion of AED programmes, coupled with widespread CPR and defibrillator training, offers the most promising path to significantly improving cardiac arrest survival rates across the UK and Ireland. These efforts empower ordinary citizens to become immediate lifesavers, making a profound difference in critical moments.
