Abstract

Introduction: We conducted a single-blind, prospective, randomized, 3-arm controlled trial to compare the efficacy of interactive and noninteractive video-based with instructor-led teaching in acquiring and retaining basic surgical skills. Methods: Participants were pretested after providing written instruction using a simulator. After the pretest, students were randomized to three groups: noninteractive video-based instruction (NIVBI), instructor-led teaching with concurrent feedback, and interactive video-based instruction (IVBI). An immediate post-test and a retention test were performed 1 mo after the practice session's end to assess the efficacy of practice conditions. Two experts blinded to the experimental condition evaluated performance using expert-based assessment. Data were analyzed using SPSS. Results: There were no differences in expert-based assessments between groups at the pretest. All three groups showed significant improvements in expert-based scores between the pretests and post-tests as well as between pretests and retention tests (P < 0.0001). Instructor-led teaching and IVBI were equally effective initially for teaching this skill to naive medical students and showed better performance than NIVBI (P < 0.0001 each). At retention, IVBI displayed superior performance compared to NIVBI and the instructor-led group (P < 0.0001 each). Conclusions: Our result showed that video-based instruction could be as effective as instructor-led teaching in acquiring basic surgical skills. These findings support the idea that with thoughtful incorporation into technical skill curricula, video-based instruction may efficiently use faculty time and serve as a helpful adjunct for basic surgical skills training. © 2023 Elsevier Inc.
