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.

Assessment of knowledge and skills in using an Automated External Defibrillator (AED) by university students. A quasi-experimental study

AIM

To evaluate layperson (university student) ability to use an automated external defibrillator (AED).

DESIGN

A repeated measures quasi-experimental study with non-probabilistic sampling and a control group was carried out.

SCOPE

Teacher training degree students at the University of Santiago de Compostela (Spain).

PARTICIPANTS

The sample consisted of 129 subjects (69% women and 31% men), between 19-47 years of age (mean 23.2±4.7 years). As inclusion criterion, the subjects were required to have no previous knowledge of AED.

INTERVENTIONS

Times to apply defibrillation with an AED to a mannequin were recorded untrained (T0), after a theoretical and practice explanation lasting less than one minute (T1), and 6 months after the training process (T2).

MAIN VARIABLES OF INTEREST

The primary endpoint was the time taken to deliver a defibrillation discharge. The "improvement effect" variable was defined by the absolute time difference between T1 and T0, while the "degree of forgetfulness effect" variable was defined as the absolute difference between T1 and T2.

RESULTS

The mean times were T0=67.7s; T1=44.2s; T2=45.9s. The time to apply defibrillation was reduced after explanation training (T1<T0) (-23.4s; P<.001). T2 proved shorter than T0 (-21.8s; P<.001) but longer than T1 (1.6s; P=.002). The improvement effect was significant (P<.001), in the same way as the degree of forgetfulness (P=.002).

CONCLUSIONS

Easy handling of AED was demonstrated, since untrained people were able to deliver a discharge. Defibrillation time was reduced after brief training. This time barely increased after 6 months.
