Abstract 292: Effectiveness of Refresher Self-Training of Chest Compression--Only Cardiopulmonary Resuscitation: A Randomized Controlled Trial
Introduction: Although refresher cardiopulmonary resuscitation (CPR) training of at least every 2 years is recommended in the 2010 Guidelines, little is known about appropriate frequency and program including self- training.
Objective: To evaluate the effectiveness of refresher self-training course at shorter period after initial training, we compared CPR skills 6 months after the chest compression-only CPR (CC-CPR) training between those with CPR self-training (refresher group) and those without (control group).
Methods: Designs: A randomized controlled trial. Participants: General public aged 18 years or older who attended 50-min CC-CPR training. Intervention: In the refresher group, participants underwent the 1-min self-training of chest compressions with training manikin 3 months after the initial training. Data collection: Six months after the initial training, a 2-min scenario-based test was conducted and CPR skills were automatically recorded. Outcomes: The primary outcome measure was the number of chest compressions with appropriate depth.
Results: Among 109 participants, 52 (94.5%) in the refresher group and 46 (92.6%) in the control group completed the 6 month evaluation. The number of chest compressions with appropriate depth tended to be greater in the refresher group, but the difference was not statistically significant (122.7 ± 85.0 vs. 91.1 ± 77.1, p=0.06). The total number of chest compressions was significantly greater in the refresher group (207.9 ± 46.7 vs. 167.9 ± 58.2, p<0.001). Time without chest compressions in the refresher was significantly shorter in the refresher group (7.7 ± 14.6 s vs 26.2 ± 24.5 s, p<0.001) (Table 1).
Conclusion: One-min refresher CPR self-training increased the number of chest compressions and reduce the time without chest compressions, but increase in the number of chest compressions with appropriate depth did not reach statistical significance.
