[Educación quirúrgica: el proceso multicanal de enseñanza-aprendizaje y la adquisición de competencias].

Background: Nowadays, there are few differences between civilian and military trauma, requiring to surgeons serving at urban hospitals, the acquisition of competences leading to implementation of management strategies for these cases. For their training, instructional designs related to surgical education, incorporating multimedia resources and favoring the multichannel teaching-learning process, have demonstrated remarkable benefits on competences acquisition by participants.

Method: Using an instructional design sustained on problems based learning and problems resolution, a digital video and its associated flat text were reviewed by the General Surgery residents, with the further application of a wide-answer problem-resolution questionnaire. Questionnaire's results were evaluated by an information-management analytic rubric, leading to obtain evidence related to competences acquisition.

Results: In this series, 17 general surgery residents were included. Using the didactic strategy of the instructional design, 76.5% (n = 13) of participants acquired the expected level-5 generic instrumental methodologic competence, consisting in a relevant making-decisions process for problems resolution.

Discussion: Incorporation of multimedia resources into instructional designs leads a significant multichannel learning and generic instrumental-methodologic competences, so that their preferential use is recommended.
