About
The goal of this clinical trial is to assess whether online suturing training is non-inferior to in-person training in developing suturing skills among medical students at Yarmouk University in a low-resource setting.
The main questions it aims to answer are:
Researchers will compare the online video-based training with Zoom feedback to live instructor-led in-person training to see if the online approach is not clinically inferior in terms of skills and knowledge acquisition.
Participants will:
Allocation concealment will be maintained, and the OSATS scores will be assessed by a blinded evaluator using a standardized checklist.
Full description
This randomized controlled trial aims to evaluate the effectiveness of online versus in-person suturing training among medical students in a low-resource setting. Suturing is a core skill expected of medical students and a critical component of surgical training. With increasing demand for flexible and accessible medical education, online learning platforms have gained popularity. However, the comparative effectiveness of virtual training versus traditional in-person instruction in delivering procedural skills remains underexplored, particularly in low-resource environments.
This trial is designed as a phase II, parallel-group, non-inferiority randomized controlled trial with stratified block randomization and blinded outcome assessment. The goal is to determine whether online video-based suturing instruction, supplemented with real-time feedback via Zoom, is non-inferior to traditional in-person training in achieving technical skill acquisition, as measured by the Objective Structured Assessment of Technical Skills (OSATS).
Study participants are pre-clinical and clinical medical students from Yarmouk University who voluntarily consent to participate and complete all phases of the study. Participants will be stratified based on prior suturing experience (Yes/No) and randomly assigned in blocks of 4 or 6 to ensure balanced distribution across both training arms.
Allocation concealment is preserved through a standardized process: participants provide informed consent and complete baseline assessments before group assignment is revealed. The intervention is delivered in one of two formats, with both groups using identical suturing kits and standardized instructional material to reduce variability.
The in-person group receives live instructor-led training during a hands-on session.
The online group receives a pre-recorded instructional video and practices independently using the kit, followed by live Zoom-based feedback from a trainer.
Following the intervention, all participants are assessed via two primary methods:
The OSATS tool used is a standardized and validated checklist evaluating multiple technical domains such as instrument handling, suture technique, and tissue approximation. The total OSATS score, which ranges based on the number of checklist items scored on a 1-5 scale, serves as the primary outcome. Knowledge scores (0-5) serve as the secondary outcome.
Statistical analysis will follow a pre-specified non-inferiority framework. Normality of score distributions will be assessed using Shapiro-Wilk tests. If assumptions are met, independent t-tests and 95% confidence intervals will be used to assess non-inferiority; if not, non-parametric alternatives (e.g., Mann-Whitney U tests) will be used. Sensitivity analyses will confirm robustness of findings using both parametric and non-parametric approaches. Within-group changes in knowledge scores will be analyzed using paired t-tests or Wilcoxon signed-rank tests, as appropriate.
To reduce potential bias, evaluator blinding is strictly maintained and only one evaluator is used to eliminate inter-rater variability. The use of standardized materials, identical kits, and consistent checklists across both groups ensures fairness and fidelity to protocol.
This study will serve as a pilot non-inferiority trial, intended to generate effect size estimates and assess the feasibility of larger-scale implementation in similar low-resource environments. While the planned sample size of 48 participants (24 per arm) may not detect moderate effect sizes with high power, it is sufficient to detect large differences and inform the design of future trials.
The broader educational aim of this trial is to provide insight into how surgical education can be adapted to virtual or remote learning formats without compromising quality, especially in regions where traditional instruction is limited by geographic, financial, or institutional constraints. Results may inform both local and international medical education strategies and support the development of cost-effective, scalable solutions to procedural training.
This project is conducted under the Live Your Dream (LYD) educational initiative and is fully self-funded by the investigator. No external funding or institutional sponsorship has been obtained. Results will be disseminated through academic conferences and peer-reviewed publication.
