Abstract P165: Effect Of A Reminder Video Using A Mobile Phone On The Retention Of Cpr And Aed Skills In Lay Responders
Background: Because the retention of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skills after training has been reported to be poor in lay responders, additional efforts should be made to ensure adequate performance. The purpose of this study was to explore whether short watching of an educational video using a mobile phone could be an effective reminder method to maintain CPR and AED skills in lay responders.
Methods: This study was a single blind case-control trial. After initial training of CPR and AED use, seventy-five male students of Reserve Officer’s Training Corps were allocated to either video-reminded group or control-group. The video-reminded group received a memory card containing a short educational video clip about CPR and AED use for own mobile phone, and was encouraged to watch the video clip repetitively. Performance of CPR and AED skills was assessed in a scenario format by examiners and by sensored manikin immediately following training and at 3 months later.
Results: The video-reminded group watched the video clip 3.8±1.8 times during 3 months. In an assessment of psychomotor skill for CPR and AED use at 3 months later, the video-reminded group demonstrated more accurate airway opening (p<0.001), checking for signs of a circulation (p<0.001), hand positioning (p=0.004), positioning of electrode (p<0.001), pre-shock safety check (p<0.001) and resuming CPR after defibillation (p<0.001) than the control group. The video-reminded group had a significantly higher self-assessed CPR competence score than the control group at 3 months later (74.9±11.6 vs. 55.2±19.7, p<0.001). However, there were no differences in compression depth, compression rate, ventilation volume and time between the two groups.
Conclusion: Repetitive watching of an educational video using a mobile phone is effective in the retention of CPR and AED skills in lay responders.
