Can a monthly online refresher keep CPR skills sharp?
NCT ID NCT07649343
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial investigates whether an online booster training system helps medical students retain high-quality CPR skills months after their initial course. Participants are medical students who have completed a standard CPR class and are randomly assigned to either receive monthly online booster sessions or no additional training. The study measures how well they perform chest compressions and pass a theoretical test three months later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Online booster training system
- What this could lead to
- If effective, this online system could help medical students maintain life-saving CPR skills with minimal extra effort.
- What could go wrong
- This is a relatively small, single-center study. The booster may not improve skill retention enough to be meaningful, and results may not apply to other groups.
