Role of Procedural Videos in Teaching the Surgery Residents

Overview

A randomized controlled trial was conducted at Pakistan Institute of Medical Sciences (PIMS) Islamabad after approval from the Institutional ethics review board. Fifty-four surgical residents in training and who have completed at least 3 months of surgical training were enrolled in the study. After the residents had performed the procedure initially, 27 were made to watch the procedural videos and learn the steps of the procedure while those of the other group did not watch the videos. Participants of both the groups were made to perform the procedure. GARS (global assessment rating score) was calculated for each individual during their second procedure. All procedures were performed under the supervision of a consultant surgeon who was blinded about the groups and make assessment of the GARS (global assessment rating score).

This study was conducted in 2 phases. In Phase-I just after the enrollment, all the residents performed the procedure from which initial GARS (global assessment rating score) assessment was made. Phase-I was followed by allocation into the groups i.e., study and control groups. In phase-2, a video of surgical procedure was obtained through internet. After all residents have done the procedure initially, 27 participants of the study group were made to watch the videos and learn the steps of procedure while those of the other group did not watch the videos. Participants of both the groups were made to perform the procedure again. GARS (global assessment rating score) was calculated for each individual in their second procedure which included following scores: 1. Respect for tissue 2. Time and motion 3. Instrument Handling 4. Depth perception 5. Bimanual Dexterity All elements scored between 1-5 with a total of 25 score. All procedures were performed under the supervision of a consultant surgeon who was blinded about the groups and make assessment according to the GARS (global assessment rating score).
