Early or Late Booster for Basic Life Support?
A study testing Early Booster Teaching and Late Booster Teaching in people with Basic Life Support, run by Ottawa Hospital Research Institute at 1 site in Canada.
Trial summary
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. Read more about this study

About this study
Official title: Does an Early Booster Session Improve Performance and Retention of Skills in Basic Life Support Compared to a Later Booster? A Simulation Based Randomized Controlled Trial
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.
Read the detailed description
Novice laypeople who have not received BLS training in the 6 months leading up to the date of participation will be recruited from the University of Ottawa and the general public. Participants will be randomized into one of three groups: early booster, late booster, or no booster (control). Currently, no booster is the educational standard. The early booster group will receive a booster at 3 weeks, the late booster at 2 months, and no booster for the control. All participants will undergo BLS training, an immediate post-test, and a retention post-test at 4 months. Post-tests involve a simulated cardiac arrest scenario. Raters will be blinded to the group allocation and simulation test order.
