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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Video-based BLS training | Experimental | 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. |
|
| Simulation-based BLS training | Experimental | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Video-based BLS training | Behavioral | A structured video-based Basic Life Support (BLS) training module covering adult CPR and AED use, delivered via standardized instructional videos. |
| Measure | Description | Time Frame |
|---|---|---|
| OSCE performance score | 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 |
| Measure | Description | Time Frame |
|---|---|---|
| BLS knowledge test score (pre-test) | Score obtained on a multiple-choice BLS knowledge test administered before training. | Baseline (before training) |
| BLS knowledge test score (post-test) | Score obtained on the same multiple-choice BLS knowledge test administered immediately after training. |
| Measure | Description | Time Frame |
|---|---|---|
| Knowledge gain | Change in BLS knowledge test score calculated as post-test score minus pre-test score. | From baseline to immediately after training |
