Outcome Measures

Primary Outcomes (2)

Trainee-reported outcomes
Immediately after practice, trainees complete a questionnaire rating the training material and the learning experience. Four items are measured on a 5-point Likert scale (1-5): material comfort/usability, perceived realism (similarity to human skin), perceived understanding of basic suturing principles, and perceived development of practical skills. Additionally, trainees rate their confidence in placing sutures on a 0-10 numeric scale.
1 day
Expert-rated technical outcomes
Experienced surgeons evaluate students' sutures across multiple domains, each scored on a 1-5 scale (1 = worst, 5 = best). For students who do not complete the task, a score of "0" is recorded, and the result is excluded from the qualitative analysis. Technical endpoints are analysed separately for simple interrupted domains, vertical mattress domains, and global composite scores, defined as the mean across available domains within a suture type. Composite scores will first be calculated at the participant level as the mean across available domains. Group-level summaries will be presented as medians with interquartile ranges (IQR) due to the non-normal distribution of scores.

Study Arms (2)

Medical students (various materials)

ACTIVE COMPARATOR

Medical students with no prior suturing experience and no known allergies to the materials used who are willing to participate in suturing on porcine skin, banana, chicken, or orange in Round 1, then on silicone model in Round 2.

Procedure: Suture skills retention

Medical students (silicone only)

SHAM COMPARATOR

Medical students with no prior suturing experience and no known allergies to the materials used who are willing to participate in suturing on a silicone model in Round 1, then on a silicone model in Round 2.

Procedure: Suture skills retention

Interventions

Suture skills retentionProcedure

Medical students with no prior formal experience in surgical suturing are randomly assigned to practice on one of five training materials using computer-generated randomisation: silicone pad, porcine skin, chicken tissue, banana peel or orange peel (study arm). All participants attend a lecture led by an experienced surgeon (academic teacher). After this, in Round 1, they practise suturing using a standardised protocol, supervised by experienced surgeons (four per group). In Round 2, trainees from all groups (silicone, porcine, chicken, banana, and orange) perform suturing on silicone pads (standardised material exposure, control arm). A pre-specified random subsample from each Round 1 arm are invited to Round 2 due to logistical constraints; selection is not performance-based. Consequently, if Round 2 has a smaller sample size than Round 1, and paired analyses of Round 1 and Round 2 would be performed only for participants with data available at both time points.
