ALVARADO I, Juan et al. A pioneer simulation curriculum of suture technique training for medical students. Rev Chil Cir [online]. 2015, vol.67, n.5, pp.480-485. ISSN 0718-4026.

Introduction: Simulation has demonstrated utility in suture skills training on surgical residents. Objective: Evaluate validity of a simulated training curriculum of basic suture skills for medical students. Methods: Study conducted on 2013. Medical students were selected from the School of Medicine of Pontificia Universidad Católica de Chile (EMPUC). The program included four theoretical sessions and six practical sessions in order to training basic surgical tasks (five in total) on a simulated rubber model: one handed knot-tying, simple suture, vertical mattress suture, subcuticular interrupted suture and subcuticular running suture. A survey was applied to the participants to qualify each element of the program, on a scale of 1 to 7 (face-validity). One task (simple suture) was recorded on video, before and after training, to be evaluated by two experts on a blind fashion (content validity). Experts measure participant skills using an OSATS (Objective Structured Assessment of Technical Skills) and operative time. Statistical analysis for non-parametric variables, median and interquartile range, significant p-value < 0.05. Results: Thirty-six medical students participated, with assistance percentage was over 80%. Students qualified the experience favorably: simulated bench-model 6.0 [5.0-6.0], assistant-students 6.5 [6.0-7.0], practical sessions 7.0 [6.0-7.0], and general evaluation 6.5 [6.0-7.0]. In the evaluation of simple suture, there was a significant improvement on OSATS (10 [5-17] vs 19 [17-21]; p < 0.001) and decrease of operative time (138 seg [101-185] vs 77 seg [67-89]; p < 0.001) after training in every participant. Conclusion: This simulated curriculum delivers an alternative method for the development of technical competencies in medical students and could be incorporated on medical schools curricula.
