Abstract 12035: Effect of 10-minute Dispatch-Assisted Cardiopulmonary Resuscitation Training in Addition to a Standard Course: A Simulation Study
Introduction: Immediate bystander cardiopulmonary resuscitation (CPR) is essential for the good outcome of sudden cardiac arrest victims. Current guidelines recommend dispatch-assisted CPR (DA-CPR), which can double the frequency of bystander CPR. Laypersons, however, are not familiar with how dispatchers provide CPR instructions. DA-CPR training may be effective at spreading DA-CPR, but this needs to be validated. The aim of this study was to determine the effectiveness of brief DA-CPR training in addition to a standard CPR training course.
Methods: We conducted a DA-CPR simulation study. Participants with no prior CPR training within 1 year were assigned randomly to one of two 90-min CPR training courses (DA-CPR Group: a standard CPR course with 10-min DA-CPR training or Standard Group: a standard CPR course with a simple introduction to how dispatchers deal with emergency calls). In the DA-CPR Group, the participants practiced the role of a dispatcher and an emergency caller. At 6 months after training, the subjects performed CPR for 2 min under instruction from off-duty dispatchers.
Results: Of the 66 participants, 59 (DA-CPR Group, 30; Standard Group, 29) completed the simulation at 6 months after training. The median time intervals between call receipt and cardiac arrest recognition or instruction for chest compressions by dispatchers were similar between both groups. However, the subjects in the DA-CPR Group provided the first compression more quickly (median time interval between call receipt and the first dispatch-assisted compression: 108 vs. 129 s, respectively, p < 0.05 Mann-Whitney U test). The quality of chest compressions was, however, similar between both groups.
Conclusions: All participants could perform DA-CPR at 6 months after training, but those in the DA-CPR Group started chest compressions more quickly. DA-CPR training might be effective for the immediate development of better cooperation between a layperson and a dispatcher.
