Barriers to automated external defibrillator use among urban residents in Khon Kaen, Thailand: A cross-sectional survey

Background Automated external defibrillators (AEDs) can improve survival rates in individuals experiencing cardiac arrest; however, their widespread use in Khon Kaen, Thailand, is limited. We aimed to understand why this life-saving technology is not being effectively utilized in the city. Methods We conducted a cross-sectional survey among residents of Khon Kaen using a structured questionnaire with both closed- and open-ended items. Closed-ended survey responses were analyzed descriptively, while open-ended responses underwent content analysis to identify major themes. Findings from both components were then integrated to provide a comprehensive understanding of barriers to AED use. Results Of 370 respondents, approximately half were willing to use an AED during cardiac arrest. However, with telephone-assisted cardiopulmonary resuscitation (CPR), the willingness to perform CPR and use an AED increased to 71%. A major barrier was the small number of trained individuals in the city (10.5%). The second significant barrier was the misunderstanding that only trained individuals are permitted to use AEDs. Respondents perceived training in CPR and AED use as essential for providing the necessary knowledge and courage, as well as authorizing and obligating them to use AEDs in real-life situations. Conclusions This study revealed that the willingness of Khon Kaen residents to use AEDs is hindered by a lack of training and misconceptions that only trained individuals can use them. Public education and training programs, along with promotion of telephone-assisted CPR, could enhance bystander response and improve AED use.
