Effects of Recorded versus Live Teleconference Didactic Lectures on Medical Student Performance in the Surgery Clerkship

Abstract

OBJECTIVEDue to the COVID-19 pandemic, numerous institutions converted medical education didactics to electronic formats including both live teleconference didactics and recorded faculty lectures. This study aims to compare the effect of recorded versus live teleconference didactic lectures on medical student examination scores during the surgery clerkship.DESIGNMedical students completing the Surgery Clerkship received a weekly series of didactic lectures taught by faculty via a teleconference (2020-2021 academic year) or recorded format (2021-2022 academic year). Performance outcomes included weekly quizzes, National Board of Medical Examiners (NBME) Surgery Shelf Exam, and clerkship Objective Structured Clinical Examination (OSCE) scores.SETTINGUniversity of Miami Miller School of Medicine.PARTICIPANTSAll second- (MS2) and third-year (MS3) medical students completing the Surgery Clerkship over two academic years (n = 312).RESULTSStudents who received live teleconference lectures (n = 156) demonstrated higher average scores on weekly quizzes (89%) and the NBME shelf exam (76%) compared to those receiving recorded lectures (n = 156; 71% quiz, 70% shelf exam), both p < 0.001. There was a significant association with performance in the highest quartile (Q1) of weekly quiz scores and receiving live lectures (40% vs. recorded lectures 1%, p < 0.001). Comparing only MS3 students, mean weekly quiz scores and Q1 achievement were significantly higher (both p < 0.001) in the teleconference cohort with no significant difference in NBME shelf exam performance (p = 0.971). No difference in OSCE performance was observed between groups.CONCLUSIONThese results suggest that synchronous teleconferences may be more effective than recorded lectures for achieving institutional learning objectives on the surgery clerkship without any negative impact on NBME shelf exam or clinical evaluation parameters. This information should be used to inform future institutional clerkship design and educational initiatives.
