Abstract 15393: High Quality CPR With Optimized Rescuer-Dispatcher Teamwork
Background: Calling the emergency phone number and starting CPR initiates the chain of survival for sudden cardiac arrest outside hospital. Traditional CPR courses teach to call for help and to perform CPR without dispatcher assistance. Traditional telephone-CPR (T-CPR) is just-in-time training for rescuers with little or no CPR knowledge, but trained rescuers also perform better with T-CPR. Mobile phone speaker allows dispatcher to continuously coach the rescuer and guide CPR performance until the ambulance arrives.
We hypothesized that optimizing rescuer-dispatcher teamwork by (A) implementing T-CPR in training and (B) using continuous dispatcher instructions during CPR would improve bystander CPR quality in a simulated scenario.
Method: Participants aged 22-69 were randomized to two different CPR courses and two different dispatcher instruction sets. The standard training (CPR anytime, Laerdal Medical) and the optimized training (Rescuer School, Laerdal Medical) were without and with T-CPR practice, respectively. The purpose of the standard instructions is to initiate compression-only while the optimized continuous instructions comprise more instructions, questions and encouragement to guide CPR performance. Participants performed 10 minutes of chest compressions-only on a CPR recording manikin, in a small confined kitchen. We compared the following groups:
(1) Standard training + standard dispatcher instructions (n=19)
(2) Optimized training + optimized continuous dispatcher instructions (n=24)
Results: Participants from group 2 delivered significantly more chest compressions (median 1043 vs. 859 compressions, p=0.001) and compressed more frequently to a compression rate between 90-120 min-1 (median 88% vs. 71% of compressions, p<0.014), compared to group 1. This also resulted in less time without compressions after CPR had started (median 6 s vs. 99 s, p<0.001). There was no difference in chest compression depth (mean 47 mm vs. 47 mm, p=0.90) or in demography, education and previous CPR training between the groups.
Conclusion: In our simulated scenario rescuers trained in T-CPR demonstrated better quality CPR with continuous dispatcher instructions compared to those with standard training and standard instructions.
