Simulation intervention with manikin-based objective metrics improves CPR instructor chest compression performance...

Area of Science:

• Medical Education
• Emergency Medicine
• Cardiopulmonary Resuscitation Training

Background:

• Cardiopulmonary resuscitation (CPR) instructor/coordinator (CPR-I/C) adherence to guidelines and learner assessment accuracy for basic life support (BLS) skills lack experimental study.
• Investigated CPR-I/C chest compression quality and assessment accuracy.
• Aimed to enhance CPR-I/C skills via cardiac arrest simulations with objective performance feedback.

Purpose of the Study:

• To determine the quality of CPR-I/C chest compressions and the accuracy of their assessments.
• To improve CPR-I/C compression and assessment skills using cardiac arrest simulations with real-time feedback.

Main Methods:

• Thirty CPR-I/Cs were randomized into control or experimental groups.
• Subjects performed chest compressions during simulations and assessed CPR videos.
• Interventions included real-time manikin feedback during a second simulation and video assessments.

Main Results:

• All CPR-I/Cs demonstrated suboptimal chest compressions initially.
• Real-time manikin feedback increased the proportion of subjects achieving >77% correct compressions (P < 0.01).
• CPR-I/C assessment accuracy for CPR videos remained low, with poor correlation between compression correctness and assessment accuracy.

Conclusions:

• Real-time compression feedback during simulation enhanced CPR-I/C chest compression performance.
• Chest compression assessment skills did not show comparable improvement with feedback.
• Identified a need to improve CPR instructor assessment accuracy alongside technical skills.
