LLM-based refreshers vs video refreshers after PALS training
Official title: Comparing the Effectiveness of Large Language Model-Based and Video-Based Refresher Education on Knowledge Retention After Simulation-Based Pediatric Cardiopulmonary Resuscitation Training: A Six-Month Follow-Up Study
Run by Samsung Medical Center · NCT07783932 · Data updated 2026-11-12
We test whether an AI-powered refresher or a video refresher better helps healthcare professionals keep PALS knowledge and skills six months after simulation training.

Is this trial a fit for you?
✓Likely a good fit
Healthcare professionals at Samsung Medical Center who have prior BLS/CPR training and can complete follow-up assessments.
✕Probably not a fit
Participants who do not respond to assessments or whose workload prevents follow-up may derive no measurable benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Participants who have completed simulation-based PALS training are randomized to receive either an AI-driven, interactive refresher using generative AI and VR, or a traditional video refresher. Three months after training, each group completes their assigned refresher, and six-month follow-up assesses knowledge, simulation performance, and confidence. The study is conducted at Samsung Medical Center in Seoul and focuses on practical retention for pediatric emergency care professionals. Outcomes include knowledge retention, performance in simulated PALS scenarios, and self-efficacy.
Why it matters
Potential benefit: If successful, the AI-powered refresher could improve long-term retention and confidence in pediatric emergency skills.
How similar studies have gone: Prior education studies suggest technology-enhanced refreshers can improve knowledge retention, but results vary by modality and setting.
