Application of Automated External Defibrillators Among the Public: A Cross-Sectional Study of Knowledge, Attitude, Practice, and Barriers of Use in Saudi Arabia

Background: The likelihood of survival of an out-of-hospital cardiac arrest quadruples with the rapid application of basic life support (BLS). The public's ability to perform cardiopulmonary resuscitation (CPR) and use automated external defibrillators (AEDs) is extremely important. This study aimed to assess the public knowledge, attitudes, and practices (KAP) of utilizing AEDs and to understand barriers to AED application.Methods: We conducted a cross-sectional study from March 1-30, 2022. An electronic questionnaire was constructed and validated to measure the KAP for public AED utilization and its barriers.Results: Of the 406 participants, 244 (60.10%) were males. Male respondents had 17% less knowledge and poorer attitude towards using an AED as compared to female respondents. Knowledge and attitudes on using AEDs were low (70.7%) among Saudi nationals compared to those of foreign nationals. Those who were BLS/CPR trained had a 2.5 times greater understanding and willingness to use AEDs in public than those who were not. Barriers to AEDs in CPR/BLS-trained participants were: (1) accidentally hurting the victim (14.3%), (2) duty as a bystander to just call the ambulance and wait for help (12.1%), (3) never taught what to do (n = 41, 18.4%), (4) did not want to be scolded if performed wrong (3.1%), and (5) never witnessed such a situation (51.6%).Conclusion: There is a strong association between knowledge of and willingness to use AEDs in emergency situations among the public. Misconceptions about AEDs hinder their use. This calls for urgent training programs through accessible technology to reach the public.

Automated summary

This study aimed to assess the public knowledge, attitudes, and practices (KAP) of utilizing automated external defibrillators (AEDs) and to understand barriers to AED application. The findings showed that male respondents had less knowledge and poorer attitude towards using AEDs compared to female respondents. Additionally, Saudi nationals had lower knowledge and attitudes towards AEDs compared to foreign nationals. BLS/CPR trained individuals had a greater understanding and willingness to use AEDs in public.
