GONZALEZ L., Roberto et al. Implementation of suture monitor workshop in undergraduate medical students. Rev. cir. [online]. 2019, vol.71, n.2, pp.122-128. ISSN 2452-4557.


Suture techniques are considered the minimum of a medical examination and are fundamental in the practice of medicine. Currently, the students of the Universidad de Concepción do not have a formal instance to acquire these competences.


To evaluate the validity of a training program for Suture Instructor (SI) students through the results obtained through a standardized assessment method, carried out in undergraduate students of medicine at the University of Concepción.


Preexperimental before and after study. A theoretical-practical intervention was carried out for six medical students of different semesters of the career, between the months of May and July 2017. It consisted of three modules: theoretical classes, practice in biological model and module in surgical pavilion supervised by subspecialists. Continuous and interrupted sutures were evaluated in the biological model using the “The Objective Structured Assessment of Technical Skills” (OSATS) scale. Results of the OSATS scale are described and compared before and after the course. Informed consent was applied. SPSS® was used for statistical analysis by Mann-Whitney test for non-parametric variables. It was considered significant p < 0.05.


All participants improved score on OSATS scale. The participants progressed significantly their results in the different OSATS scales (5.2 vs 8.8, p < 0.05 and 16.5 vs 27.2, p < 0.05) when comparing pre vs post intervention results respectively.


Our experience shows that it is possible to create an SI training workshop with excellent results for medical students, through a three phase training program, with theory classes, simulation and “in vivo” practice. It also constitutes the basis of future research that seeks to solve the lack of a formal program of teaching suture techniques to medical students of our university.
