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

August 19, 2026 updated by: Samsung Medical Center

This study aims to compare the effectiveness of large language model (LLM)-based refresher education and video-based refresher education for maintaining knowledge and performance after simulation-based Pediatric Advanced Life Support (PALS) training.

Healthcare professionals will be randomly assigned to either an LLM-based refresher education group or a video-based refresher education group. After randomization, all participants will receive simulation-based PALS training. Three months after the initial training, participants will receive refresher education according to their assigned group. The LLM-based group will use a generative AI and virtual reality-based educational platform that allows interactive practice of pediatric emergency scenarios, while the video-based group will receive video-based refresher education.

At six months after the initial training, knowledge retention, simulation-based PALS performance, and self-efficacy will be assessed. The primary objective is to compare simulation-based performance between the two groups at six months. Secondary outcomes include knowledge test scores, self-efficacy, and measures related to completion of the refresher education.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Simulation-Based PALS Performance Assessment Score
Time Frame: 6 months after the initial simulation-based PALS training
PALS performance will be assessed using a predefined checklist during a simulation-based PALS performance assessment. Performance scores will be compared between the LLM-based refresher education group and the video-based refresher education group.
6 months after the initial simulation-based PALS training

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in PALS Knowledge Test Score From Baseline to 6 Months
Time Frame: Baseline and 6 months after the initial simulation-based PALS training
PALS knowledge will be assessed using the same 25-item knowledge test at baseline and 6 months after the initial simulation-based PALS training. The change in knowledge test score from baseline to 6 months will be compared between the two groups.
Baseline and 6 months after the initial simulation-based PALS training
PALS Knowledge Test Score at 6 Months
Time Frame: 6 months after the initial simulation-based PALS training
PALS knowledge will be assessed using a 25-item knowledge test. Knowledge test scores at 6 months after the initial simulation-based PALS training will be compared between the two groups.
6 months after the initial simulation-based PALS training
Pediatric Resuscitation Self-Efficacy Score at 6 Months
Time Frame: 6 months after the initial simulation-based PALS training
Self-efficacy related to pediatric resuscitation will be assessed using the Pediatric Resuscitation Self-Efficacy Scale (PRSES). PRSES scores at 6 months after the initial simulation-based PALS training will be compared between the two groups.
6 months after the initial simulation-based PALS training
