Early or Late Booster for Basic Life Support?

Attrition of skills after basic life support (BLS) training is common. Psychology studies have established that for basic memory recall tasks, spaced learning strategies improve retention. Spaced learning is often organized as a refresher or 'booster' course after initial training. This study aims to investigate if this principle holds true for BLS skills, which require rapid memory recall and efficient deployment of procedural skills while under time pressure.
