PP29 Perceptions of over 65-year-olds regarding the use of drone-delivered defibrillators as bystanders in out-of-hospital cardiac arrest: a qualitative study

<h3>Background</h3> Out-of-hospital cardiac arrest (OHCA) presents a significant public health challenge in the UK and low survival rates. While public access defibrillators (PADs) can enhance outcomes, they are rarely used due to factors such as lack of awareness and accessibility. Drone delivered AEDs are being explored to improve bystander defibrillation, however there is minimal evidence to explore the perceptions of older persons regarding the technology. This study aimed to explore the perspectives of individuals aged 65 and older on the deployment of drone technology for AED delivery in OHCA situations. <h3>Methods</h3> Qualitative interviews were conducted with 12 participants aged 65 and older to gather insights into their perceptions about drone AED delivery whilst acting as a solo bystander in an OHCA situation. Thematic analysis was used to identify key themes from the data. <h3>Results</h3> Participants conveyed complex responses regarding the interaction between humans and drone-delivered AEDs, highlighting concerns about using the AED correctly and the emotional difficulty of leaving a patient alone. Many expressed guilt over potentially not being able to use the AED effectively in high-pressure situations. In terms of views towards the use of a drone AED delivery system, participants recognised its potential as a lifesaver by improving response times in cardiac arrest scenarios but raised concerns about safety and practical navigation challenges. Lastly, there was a consensus on the need for public education and training to enhance confidence in using both the AED and the drone system. <h3>Conclusions</h3> This study highlights the perceptions of older adults regarding drone-delivered AEDs in OHCA situations. While participants appreciated the rapid delivery of AEDs via drones, they expressed significant concerns about their ability to use the devices and the emotional burden associated with emergency situations. The findings emphasise the need for enhanced public education and psychological support to ensure effective bystander intervention and to bridge the gap between technological acceptance and practical application.
