Abstract 16183: High Long-Term Retention Rate of Hands-Only Cardiopulmonary Resuscitation Skill Achieved by Audio-Visual-Practice Reinforcement: A Randomized Placebo Controlled Clinical Trial
Objective: Adequate bystander CPR skill especially high quality chest compression (CC) is vital for providing effective resuscitation of out of hospital cardiac arrest (OHCA), however survival rates remain low due to rapid skill deterioration following training. We aimed to examine the effectiveness of two reinforcement models (audio-visual [AV] and audio-visual-practice [AVP]) on skill retention of traditional and hands-only CPR.
Method: Family members of people who were at higher risk of OHCA were recruited in Beijing, China. All participants received a 90-min CPR training and then were assigned randomly into one of the three groups. The control group was given a CPR instruction booklet and a placebo DVD without any further reinforcement. Both AV and AVP groups were given a CPR instruction booklet and an instruction DVD, and the skills were reviewed and reinforced by a telephone reminder every 3 months. The AVP group was also given a CPR practice dummy and asked to practice the skills while watching the instruction DVD. The trainees’ CPR skills and knowledge were assessed immediately and 18 months after training and compared using χ2 or ANOVA. The instructors and evaluators were blinded to the group assignments.
Results: A total of 237 participants finished the study. The retention rate of CPR skills in both AVP and AV groups were higher than the control group at 18 months after training, but no difference was observed between AVP and AV groups. Further analysis revealed that skill retention rate of hands-only CPR reached 64.0 % in the AVP group, which was 19.2% and 42.8% higher than AV and control groups (P = 0.012 and < 0.001 respectively).
Conclusions: Both AVP and AV reinforcement models revealed better long-term retention of CPR skills for family members of people at high risk of OHCA. The AVP model was most effective for retention of hands-only CPR skill, which suggests that by using this model, 19 and 43 more OHCA victims may get high quality CC for every 100 victims resuscitated.
