Effectiveness of simplified chest compression-only CPR training program with or without preparatory self-learning...

Area of Science:

• Emergency Medicine
• Public Health Education

Background:

• Cardiopulmonary resuscitation (CPR) is a critical intervention for cardiac arrest survival.
• Chest compression-only CPR is a simplified approach recommended for lay rescuers.
• Evaluating adjuncts to practical training can optimize public preparedness.

Purpose of the Study:

• To assess the efficacy of a 1-hour chest compression-only CPR training program.
• To determine if a preparatory self-learning video enhances CPR training outcomes.

Main Methods:

• Randomized controlled trial comparing a 1-hour practical CPR training with and without a pre-training video module.
• Primary outcome: total chest compressions during a 2-minute test period.
• Secondary outcomes included initial CPR attempt rates and automated external defibrillator (AED) usage.

Main Results:

• The video group showed higher initial CPR attempt rates (92.6% vs 64.4%) and AED usage (74.7% vs 28.7%) before practical training.
• The video group performed significantly more chest compressions initially (100.5 vs 74.4).
• After 1-hour practical training, compression numbers increased significantly in both groups, with no significant difference between them (161.0 vs 159.0).

Conclusions:

• One-hour practical chest compression-only CPR training enables satisfactory performance by the general public.
• While a self-learning video can increase initial engagement, practical training remains essential for achieving adequate performance levels.
• The study highlights the critical role of hands-on training in CPR preparedness.
