Effectiveness of Automated External Defibrillator training using different Automated External Defibrillator models in teaching and assessment in 10th Grade Students: A Randomized Controlled, Double-Blinded Trial
Keywords:
AED, AED training, Basic life support, CPRAbstract
Non-healthcare providers are allowed to use AEDs without prior training. Despite this, recent study showed that approximately 20% of schoolchildren without prior training are able to use an AED correctly.
Primary objective was to study the effectiveness of AED training using different models of AEDs in teaching and assessment.
Method: This study, a randomized control trial, double-blinded was conducted on 10th grade students in Chiang Mai province. Participants were randomly allocated into two groups: forty students were enrolled into the first group, where different AED models were used; 40 students were enrolled into the second group, where the same AED models were used for teaching and assessment sessions. Teaching sessions were provided by BLS instructors, and assessment sessions immediately followed the teaching sessions. Study end point was pass or fail, and time to first shock. Statistical analysis was performed using Exact probability test and Mann-Whitney U Test.
Results: Eighty 10th grade students in Chiang Mai province were enrolled into the study. The mean age of the first group was 15.570.50 years, and 15.650.48 years for the second group. Age, sex, average GPA grades, previous BLS knowledge, and AED models used were not statistically different. Thirty-five students (87.50%) and 36 students (90.0%) passed the practical assessment in the first and second groups, respectively. Time to first shock was 50 seconds (iqr 20.7) and 46.5 seconds (iqr 16.2) in the first and second groups, respectively (p-value= 0.447).
Conclusion: AED training by using different AED models in the teaching and assessment models does not yield a significant difference in correct AED usage nor time to first shock.
