Randomized Controlled Trial
Early or late booster for basic life support skill for laypeople: a simulation-based randomized controlled trial.
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. ⋯ A late booster session improves BLS skill retention at 4 months in laypeople.
