The timing of booster sessions may not improve resuscitation skill retention among healthcare providers: a randomized controlled trial.

Introduction: Booster sessions can improve cardiopulmonary resuscitation (CPR) skill retention among healthcare providers; however, the optimal timing of these sessions is unknown. This study aimed to explore differences in skill retention based on booster session timing.

Methods: After ethics approval, healthcare providers who completed an initial CPR training course were randomly assigned to either an early booster, late booster, or no booster group.

Early or late booster for basic life support skill for laypeople: a simulation-based randomized controlled trial.

Purpose: Retention of skills and knowledge has been shown to be poor after resuscitation training. The effect of a "booster" is controversial and may depend on its timing. We compared the effectiveness of an early versus late booster session after Basic Life Support (BLS) training for skill retention at 4 months.
