Improvement of suturing skills after training. Presentation of a simulation and evaluation model.
Abstract
Introduction. Acquiring surgical skills through simulation is a growing need nowadays. Every day more, patient safety is valued, and therefore it is
unacceptable that surgeons without previous training attend patients. Our objective is to develop a low-cost simulation system, and a score, which allows
evaluating the acquisition of knowledge. Methods. 6 first-year ophthalmology residents were chosen to perform two recorded sessions, where they performed different suture techniques. Between them, the residents were allowed to complete a 4-session training. After completing the training, the initial and final sessions were evaluated by 3 blind expert surgeons. Mann–Whitney tests were
used to compare scores. And the agreement between the three evaluators was checked using the Fleiss´ kappa concordance test. Results. The concordance in
the evaluation between the three examiners was substantial, κ= 0,71 (IC 95%, 0,33 a 0,82), p < .0005. Residents improved their median performance scores after completion of training (6,52 vs 7,81) however, no significant differences were found due to the small number of participants. Conclusion. We developed a low-cost, portable training system with acquisition of skills in a group of residents.We have also developed an evaluation scale that allows to objectively assess
progression.
