Advanced Life Support Operational Skills and Theoretical Knowledge Learning and Memorization
Conditions
Brief summary
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.
Detailed description
Advanced life support is crucial for medical students during their studies, examinations, and professional practice, serving as the foundation of their clinical skills. Scenario-based simulation training immerses students in realistic emergency scenarios, familiarizing them with equipment operation, fostering teamwork, and providing real-time feedback to mitigate clinical risks. Through scenario simulation, students encounter and manage authentic emergency situations within simulated clinical settings, thereby enhancing their skill proficiency and response capabilities. Intermittent training combined with deliberate practice helps medical students retain these skills and emergency knowledge over the long term. This study aims to investigate the impact of a teaching model integrating scenario simulation training with spaced practice, compared to traditional teaching methods, on medical students' long-term mastery of advanced life support theoretical knowledge and operational skills.
Interventions
Through 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.
OTHERTraditional Training plus Interval Training Group
Through 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.
OTHERScenario Simulation Group
The 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.
OTHERScenario Simulation plus Interval Training Group
Members 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.

Inclusion criteria
* 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.
Exclusion criteria
* 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. * Individuals who are unable to guarantee participation in all scheduled training or testing sessions during the study period (particularly on Days 2, 4, 6, and 7) due to scheduling conflicts, leave requests, or other reasons.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Advanced Life Support Practical Skill Test Score | Day 7 | 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 | Day 7 | Adult Advanced Life Support Theoretical Examination Items Based on the 2025 American Heart Association Guidelines for CPR and ECC. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Scenario-Based Simulation Training Participant Behavior Checklist | Day 7 | 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 | Day 7 | 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 | Day 7 | The General Self-Efficacy Scale (GSES) developed by Schwarzer \& Jerusalem was used to investigate trainees' self-efficacy after training. |
