Abstract
INTRODUCTION
The fundamental elements of neurosurgical care are essential for all medical students regardless of their ultimate clinical specialty. However, the high-pressured neurosurgical environment leaves limited time for teaching medical students. One potential solution is the use of video-based education modules, but the effectiveness and usage of these modules in surgery is unclear.
METHODS
A 2-wk asynchronous, VBE (video based education) curriculum of four key neurosurgical topics as outlined in the Congress of Neurological Surgeons' curriculum for medical students (Intracranial Hemorrhage, Neuro-Imaging, Hydrocephalus, and Glasgow Coma Scale) was created and implemented for surgery clerkship students (n = 65). On day 1 of the study, each student was randomly assigned to 1 of 2 pairs, given a pretest for knowledge and self-efficacy on all 4 topics, and provided with the link for 2 of the 4 VBE modules. On day 14, a post-test for knowledge and self-efficacy on all four topics was completed. Usage analytics were employed to track views of assigned content.
RESULTS
Students who watched the modules (n = 53) increased their knowledge (+11.0%, P = .001) and self-efficacy (+1.37, P = .001) from pre- to post. Students who did not watch the modules (n = 12) showed no change in knowledge (58.8% vs 58.3%, P = NS), but a significant increase in their self-efficacy ratings (+1.42, P = .009). Learning analytics revealed that vast majority of learners (81%) engaged with the curriculum and watched their assigned videos once or on multiple occasions. 19% of learners did not engage with the curriculum, citing their heavy workload as a primary reason.
CONCLUSION
This study shows that a focused, asynchronous, VBE curriculum in neurosurgery has a significantly positive effect on knowledge and self-efficacy scores amongst medical students. Future studies will investigate how to improve learner compliance and better understand the gap in knowledge improvement vs self-efficacy.
