Objectives

Narrative objectives1

Assessment

Primary outcomes

Simulated scrub-role performance assessed using a 20-item procedure-specific observational checklist with a total score of 0-40 in the Clinical Skills Laboratory. Assessments were performed at baseline, immediately after completion of the intervention, and at 4-week follow-up.

Key secondary outcomes

Procedure-specific knowledge, assessed using a 25-item multiple-choice Laparoscopic Cholecystectomy Knowledge Assessment Test, at baseline, immediately after the intervention, and at the 4-week follow-up.
Perceived perioperative competence, assessed using the 33-item Perceived Perioperative Competence Scale-Revised (PPCS-R), at baseline, immediately after the intervention, and at the 4-week follow-up.
Safety attitudes, assessed using the 30-item Safety Attitudes Questionnaire (SAQ), at baseline, immediately after the intervention, and at the 4-week follow-up.

Interventions/Control_1

Intervention group: Participants received the standard faculty-approved training for laparoscopic cholecystectomy plus simulator-based training using the Touch Surgery mobile application. The Touch Surgery training consisted of three 45-minute self-directed practice sessions over one week. Participants completed all five stages of the Laparoscopic Cholecystectomy module on their personal smartphone or tablet. A research assistant was available for technical support and adherence monitoring.

Interventions/Control_2

Control group: Participants received only the standard faculty-approved training for laparoscopic cholecystectomy, consisting of theoretical teaching followed by practical orientation in the Clinical Skills Laboratory. No additional cognitive simulator or digital training platform was provided.

Results

Among 80 randomized students, Touch Surgery plus standard training produced greater improvements than standard training alone in simulated scrub-role performance (Time x Group P<0.001, partial eta2=0.195), knowledge (P<0.001, eta2=0.147), and perceived perioperative competence (P<0.001, eta2=0.269). No significant differential change was observed in safety attitudes (P=0.373, eta2=0.013). All 80 participants completed follow-up and were analyzed.

Baseline Characteristics

A total of 80 undergraduate operating room technology students were randomized, with 40 participants in each group. In the control group, mean age was 21.71 +/- 1.03 years, 26 participants (65.0%) were female and 14 (35.0%) were male, mean GPA was 16.33 +/- 1.02, 27 (67.5%) had prior limited exposure to laparoscopic surgery, and mean instrument familiarity score was 2.48 +/- 0.81. In the intervention group, mean age was 21.42 +/- 1.14 years, 23 participants (57.5%) were female and 17 (42.5%) were male, mean GPA was 16.54 +/- 0.91, 29 (72.5%) had prior limited exposure, and mean instrument familiarity score was 2.68 +/- 0.76. No statistically significant baseline differences were observed between the groups.

Participant flow

A total of 80 participants were randomized: 40 to Touch Surgery plus standard training and 40 to standard training alone. All 40 participants in each group received the intended intervention or control condition and completed the immediate post-test and 4-week follow-up assessments. There were no withdrawals, losses to follow-up, or exclusions after randomization. All 80 randomized participants were included in the intention-to-treat analysis.

Adverse events

No adverse events, unintended effects, or significant technical failures were reported during the intervention or follow-up period.

The post-test between-group mean difference was 13.62 points, 95% CI 4.72 to 22.53, with Cohen's d=0.68.

Touch Surgery group scores were 99.53 +/- 11.40, 102.60 +/- 14.32, and 102.35 +/- 13.88, respectively. The Time x Group interaction was not statistically significant, F(2,156)=0.99, P=0.373, partial eta2=0.013.
