This study aims to investigate medical students' mastery of advanced life support skills when using scenario-based simulation combined with intermittent training, compared to traditional teaching methods.
Medical students studying in the Department of Anesthesiology
The initial training for "Advanced Life Support Scenario Simulation Instruction" required by this study has been successfully completed, and the corresponding pre-test assessment has been passed.
Voluntarily participate in this study and sign a written informed consent form, committing to adhere to the entire schedule of the research plan.
During the research period, do not participate in any other training that conflicts with this experiment.
Individuals who have previously obtained an Advanced Cardiac Life Support (ACLS) provider certificate issued by the American Heart Association (AHA) or an equivalent organization, and whose certificate remains valid.
Individuals who have participated in any form of Advanced Cardiac Life Support (ACLS) or Advanced CPR scenario simulation training courses within the past three months.
Previously participated as a subject in educational interventions comparing "spaced learning versus traditional learning."
Individuals who, for any reason, fail to complete all instructional components during the initial training phase or whose pre-test data is missing.
Parallel
Traditional Training Group
Other interventionThrough basic skills training and testing, confirm that all trainees have mastered the steps of adult external cardiopulmonary resuscitation (CPR), tracheal intubation procedures, and the operational steps of automated external defibrillators (AEDs). And validated students' mastery of ECG interpretation for cardiac arrest and arrhythmias, along with pharmacology knowledge of cardiovascular emergency medications through assessment questions. After unified training, no further training is arranged for the traditional training group, and the post-test is conducted on the 7th day.
Traditional Training plus Interval Training Group
Other interventionThrough basic skills training and testing, confirm that all trainees have mastered the steps of adult external cardiopulmonary resuscitation (CPR), tracheal intubation procedures, and the operational steps of automated external defibrillators (AEDs). And validated students' mastery of ECG interpretation for cardiac arrest and arrhythmias, along with pharmacology knowledge of cardiovascular emergency medications through assessment questions. The traditional training combined with interval training group receives theoretical and skill knowledge reviews on days 2, 4 and 6 after unified training, and takes the post-test on day 7.
Scenario Simulation Group
Other interventionThe scenario simulation group learns advanced life support theories and practical skills through scenario simulation cases. A pre-test is implemented after learning to confirm that all trainees have mastered relevant theories and operational skills. The pre-test includes cardiopulmonary resuscitation, defibrillation, endotracheal intubation, electrocardiogram interpretation and emergency drug administration, and all trainees achieve qualified scores. No further review on advanced life support is arranged thereafter, and the post-test is carried out on the 7th day.
Scenario Simulation plus Interval Training Group
Other interventionMembers of the scenario simulation combined with interval training group learn advanced life support theories and practical operational skills through scenario simulation cases. A pre-test is arranged after learning to ensure all trainees have mastered relevant theories and operational skills. The pre-test covers cardiopulmonary resuscitation, defibrillation, endotracheal intubation, electrocardiogram interpretation and emergency medication application, and all trainees pass the pre-test. They conduct reviews of standard scenario simulation videos and theoretical knowledge on days 2, 4 and 6, and receive the post-test on day 7.
Advanced Life Support Practical Skill Test Score
The scoring criteria for CPR, tracheal intubation and defibrillation in national residency training are compiled based on WS/T 839-2024, the 2023 residency training graduation assessment standards, AHA/ILCOR international guidelines and domestic expert consensus.Each skill test is scored out of 100 points; a higher score indicates better mastery of the corresponding operational skills.
Score of Advanced Life Support Theoretical Knowledge Test
Adult Advanced Life Support Theoretical Examination Items Based on the 2025 American Heart Association Guidelines for CPR and ECC.
Scenario-Based Simulation Training Participant Behavior Checklist
Participants conduct scenario simulation according to scripts compiled based on the rescue procedures for cardiac arrest patients. The participant behavior checklist is formulated in line with the standardized advanced life support resuscitation procedures specified in the 2025 American Heart Association Guidelines for CPR and ECC, covering core dimensions including basic life support quality, advanced life support procedures, team cooperation and communication, clinical decision-making and emergency response ability, as well as professional literacy and overall performance. This scale is adopted to score participants' practical performance.
Student Satisfaction Survey Form
A trainee satisfaction questionnaire was developed based on training content, adopting a 5-point Likert scale. The questionnaire evaluates trainees' experience across five dimensions: training content, teaching methods, instructors, teaching resources including venues and equipment, and training outcomes. Each dimension contains specific evaluation items, with individual item scores summed to calculate the overall satisfaction score.
Self-efficacy
The General Self-Efficacy Scale (GSES) developed by Schwarzer \& Jerusalem was used to investigate trainees' self-efficacy after training.
