    ObjectiveTo determine the effectiveness of video-based teaching in surgery residents by comparing it to the routine operating room traditional teaching.MethodologyThe randomized control trial was done at four institutions from September 2022 to March 2023. Interventional group underwent video-based instruction of basic surgical skills whereas the control group was taught through traditional operating room teaching. Pre and post-test mean scores were analyzed on SPSS version 20 through paired t-test. Learning gain was calculated. Supervisors' perceptions were recorded on survey form regarding direct observations and recorded video evaluations of resident skills on post-test.ResultsOut of sixty (n=60), fifty-five newly inducted surgical residents completed the study including both females (n=13) and male residents (n=42). Video intervention Group (27.93±3.72) and control group (23.07±4.62) both showed improvements in their post-test scores as compared to pretest scores of 13.68±3.25 and 13.52±3.60 respectively. Mean score difference improvement was more in video intervention group (13.9±3.8) in comparison to control group (9.5±4.3) provided both groups exhibits improvements in all seven domains of the global rating system (reflected by the p <0.0001). However, learning gain of 65% was observed in intervention group as compared to learning gain (41%) of control group. Evaluators(n=5) observed that recorded video evaluations helped to provide integrated feedback, despite being time (40%) and resource intensive (60%).ConclusionVideo-based teaching has higher learning gain irrespective of the fact that both groups exhibit statistically significant results in all seven domains of the global rating system. Recorded video evaluation was found feasible and reliable tool for formative assessment.Copyright: © Pakistan Journal of Medical Sciences.
