Abstract 19508: Remote Supervised Reinforcement of Cardiopulmonary Resuscitation Skills by Telephone Improves One-Year Retention: A Randomized-Controlled Trial
Objective: Bystander CPR is an effective way of improving the outcome of out of hospital cardiac arrest (OHCA). However, the survival rate of OHCA remains < 10% due to rapid skill deterioration following CPR training. We explored the effect of two remote supervised review models (audio-visual [AV] and audio-visual-practice [AVP]) on CPR skill retention.
Method: Family members of patients at high risk of sudden cardiac arrest (SCA) were recruited from communities in Beijing, China. All subjects received a 90-min CPR course, and a CPR instruction booklet for review at home as needed. At the end of the course, if the subjects passed the skill test, they were randomized into one of the 3 groups (AV, AVP, and control) using sealed envelopes. The AV group was provided with a CPR instruction video (CPR-V) and asked to watch it every 3 months. The AVP group was provided with a practice dummy (designed for the project) as well as a CPR-V, and asked to practice their skills on the dummy while watching the CPR-V every 3 months. Both groups were given telephone follow up every 3 months to encourage compliance. The controls were given a placebo video without follow up. CPR skills were re-assessed after 12 months using Resusci Anne recording manikins. The subjects, the instructors, and the evaluators were blinded to the group assignment.
Results: Of the 262 family members who finished the study, the retention rates of overall, and key elements of CPR skills were significantly higher in the AVP and AV groups, compared to the control group. Skill retention was higher in the AVP group compared to the AV group.
Conclusion: Both review models improved long-term CPR skill retention for family members of high-risk patients with SCA. The AVP model was more effective than the AV model especially for skills related to performing high quality chest compression.
