Video-Based Versus Simulation-Based Basic Life Support Training in Medical Students (BLS-VIDEO-SIM)

January 26, 2026 updated by: Serkan TELLİ, Kutahya Health Sciences University

Video-Based Versus Simulation-Based Basic Life Support Training in Medical Students: A Randomized Trial

This randomized educational trial compared a structured video-based Basic Life Support (BLS) training program with simulation-based BLS training among fourth-year medical students. Participants were allocated to one of the two training formats and completed a BLS knowledge test before and immediately after training. Performance was assessed using an Objective Structured Clinical Examination (OSCE) conducted 3 weeks after training. The primary outcome was OSCE performance at 3 weeks, and secondary outcomes included knowledge test scores and knowledge gain.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Video-based BLS training
Participants received a structured video-based Basic Life Support (BLS) training module covering adult CPR and AED use, delivered as standardized instructional videos. After viewing the module, participants completed the planned practice session(s) according to the curriculum and subsequently underwent the scheduled assessments.
Behavioral: Video-based BLS training
A structured video-based Basic Life Support (BLS) training module covering adult CPR and AED use, delivered via standardized instructional videos.
Experimental: Simulation-based BLS training
Participants received instructor-led, simulation-based Basic Life Support (BLS) training using manikins and scenario-based practice focused on adult CPR and AED use. Training was delivered according to the curriculum, followed by the scheduled assessments.
Behavioral: Simulation-based BLS training
Instructor-led simulation-based Basic Life Support (BLS) training using manikins and scenario-based practice focused on adult CPR and AED use.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
OSCE performance score
Time Frame: 3 weeks after training
Total score obtained on a standardized Basic Life Support (BLS) Objective Structured Clinical Examination (OSCE) checklist. Higher scores indicate better performance.
3 weeks after training

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
BLS knowledge test score (pre-test)
Time Frame: Baseline (before training)
Score obtained on a multiple-choice BLS knowledge test administered before training.
Baseline (before training)
BLS knowledge test score (post-test)
Time Frame: Immediately after training
Score obtained on the same multiple-choice BLS knowledge test administered immediately after training.
Immediately after training

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Knowledge gain
Time Frame: From baseline to immediately after training
Change in BLS knowledge test score calculated as post-test score minus pre-test score.
From baseline to immediately after training
