Efficacy of a Simplified Feedback Trainer for High-Quality Chest Compression Training: A Randomized Controlled...

Area of Science:

• Emergency Medicine
• Medical Simulation
• Cardiopulmonary Resuscitation Training

Background:

• International guidelines advocate for feedback devices in chest compression (CC) training.
• Cardiopulmonary resuscitation (CPR) training quality is crucial for patient outcomes.
• Evaluating novel training methods is essential for enhancing resuscitation skills.

Purpose of the Study:

• To compare the training efficacy of a simplified external cardiac massage (ECM) trainer with a traditional CPR simulator.
• To assess the impact of a simplified feedback trainer on the quality of chest compressions.
• To determine if a simplified trainer can achieve comparable results to established simulation methods.

Main Methods:

• Sixty soldiers were randomized into three groups: simplified ECM trainer (Soul Sheath™), traditional manikin (Resusci Anne), and control.
• Training duration was 7 days, followed by a blind 2-minute CPR skills assessment.
• Primary outcome: proportion of effective CC; Secondary outcomes: CC rate, depth, position, and release.

Main Results:

• The simplified trainer group achieved effective CC rates comparable to the traditional manikin group (77.0% vs. 77.5%, p=0.922).
• Both simplified and traditional groups showed significantly higher effective CC rates than the control group (p=0.037).
• Both training groups demonstrated superior CC rates and reduced shallow compressions compared to the control group.

Conclusions:

• The simplified ECM trainer (Soul Sheath™) is as effective as traditional manikin simulators for improving CPR skills.
• This simplified device offers a comparable alternative for chest compression training.
• Feedback-enabled simplified trainers can enhance the quality of CPR delivery.
