Training seniors in the operation of an automated external defibrillator: A randomized trial comparing two training methods

Study objective: This study evaluated the differences in efficacy of 2 meth ods for training seniors in the use of an automated external defibrillator (AED). We tested the hypothesis that each training method (face-to-face ins truction compared with video-based instruction) would result in similar AED performance on a manikin. Methods: Two hundred ten seniors from various senior centers were randomize d to receive face-to-face or video-based instruction on AED skills. Seniors were assessed individually and tested on the speed and quality of AED perf ormance. We retested 177 of these initial trainees 3 months after initial t raining. Similar performance measures were assessed. Results: Although there were statistically significant differences between the 2 training methods in terms of average time to shock at both evaluation s, the results in general demonstrate that there were no clinically meaning ful distinctions (time differences of <20 seconds) between the AED performa nce of seniors trained with a video and seniors trained in a face-to-face s etting at the initial training or at the retention assessment. At the initi al evaluation, overall performance was satisfactory, with greater than 98% trained with either method delivering a shock. However at the 3-month follo w-up almost,, one fourth of trainees were not able to deliver a shock, and almost half were not able to correctly place the pads on the manikin. Conclusion: We believe that seniors can be trained equally well in AED perf ormance with video-based self-instruction or face-to-face instruction. How to maintain acceptable AED performance skills over time remains a challenge .
