Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Experimental: Traditional Training Group
Conduct experiments on trainees who have mastered advanced life support theory and practical skills. After unified training, no further training is arranged for the traditional training group, and the post-test is conducted on the 7th day.
Other: Traditional 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. After unified training, no further training is arranged for the traditional training group, and the post-test is conducted on the 7th day.
Experimental: Traditional Training plus Interval Training Group

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Advanced Life Support Practical Skill Test Score
Time Frame: 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.
Day 7
Score of Advanced Life Support Theoretical Knowledge Test
Time Frame: Day 7
Adult Advanced Life Support Theoretical Examination Items Based on the 2025 American Heart Association Guidelines for CPR and ECC.
Day 7

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Scenario-Based Simulation Training Participant Behavior Checklist
Time Frame: 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.
Day 7
Student Satisfaction Survey Form
Time Frame: 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.
Day 7
Self-efficacy
Time Frame: Day 7
The General Self-Efficacy Scale (GSES) developed by Schwarzer & Jerusalem was used to investigate trainees' self-efficacy after training.
