Computer-Based Video Instruction for Training Medical Students on Skin Biopsies

BACKGROUND The development of procedural skills is necessary for medical students. Computer-based video instruction (CBVI) increases knowledge and procedural skills. OBJECTIVE This pilot study's aim was to investigate the usefulness of CBVI in dermatologic procedure training for medical students and secondarily assess students' overall perception of the field of dermatology. METHODS Twenty-nine first- and second-year medical students were randomly assigned to the CVBI group or control group, in addition to in-person instructor demonstration of shave and punch biopsies using fresh cadaver tissue. Blinded evaluators graded student performances using a five-point Likert scale immediately after demonstration, and 1 week later to assess knowledge retention. RESULTS In overall performance, the CBVI group demonstrated higher scores both in shave (3.54 vs 2.59, p = .01) and punch biopsies (3.63 vs 2.88, p = .01) at immediate recall and knowledge retention (3.68 vs 2.67, p = .01; 4.00 vs 2.99, p
