Acquisition of Surgical Skills in Medical Students via Telementoring: A Randomized Controlled Trial

Abstract

Pandemic related changes have radically altered the delivery of medical teaching. The practical skills of medicine which students should be proficient in at time of graduation have tended to require in-person tutelage, with reduced access resulting in the risk of skill deficits in newly qualified doctors. Small group teaching sessions are amenable to a virtual mode of delivery, with the ability of the virtual platform to confer practical skills unproven. The objective of the study was to evaluate the use of teleproctoring in acquisition of suturing skills in medical students. This was a single blinded two- armed randomized control trial. Medical students undergoing clinical rotations in their penultimate and final years who were able to complete the suturing tutorial were invited to participate in this study. Control groups underwent conventional suturing training under direct supervision, with the interventional group undergoing the tutorial in a remote learning setting via live streaming. Pre- and post-test assessment was carried out using validated suturing Global Rating Scale tool. A total of 24 participants were recruited, with 23 participants completing the task. Adequacy of sampling was demonstrated in both groups using Box's M test (P = 0.9). Participants' individual and composite scores were comparable at baseline (P = 0.28) and following the tutorial (P = 0.52). Participants improved to a statistically significant degree regardless of method of teaching delivery, in all skill parameters (P < 0.001). Teleproctoring is an effective tool in the provision of teaching basic suturing skills in medical students. Research on its use in more complex practical skills is warranted.
