ABSTRACT
Introduction: Virtual classroom training (VCT) is a novel educational method that permits accessible, distanced interactive expert instruction. We aimed to evaluate the efficacy of VCT in comparison to face-to-face training (FFT) and non-interactive computer-based learning (CBL) for basic surgical skills training. Method: 72 participants recruited from five London medical schools underwent stratified block randomisation into three equal intervention groups based on subjective and objective suturing experience. VCT was delivered via the BARCO weConnect platform and FFT was provided by expert instructors. Optimal student-to-teacher ratio was used, 12:1 for VCT and 4:1 for FFT. The assessed task was interrupted suturing with hand-tied knots. The primary outcome was post-intervention Objective Structured Assessment of Technical Skills (OSATS) score, adjudicated by two blinded experts and adjusted for baseline proficiency. Results: VCT was non-inferior to FFT (adjusted difference 0.44, 95% CI: -0.54 to 1.75, delta 0.675), VCT was superior to CBL (adjusted difference 1.69, 95% CI 0.41 to 2.96) and FFT was superior to CBL (adjusted difference 1.25, 95% CI 0.20 to 2.29). FFT alone was associated with student travel expenses (mean £4.88, SD 3.70). Instructor hours used per student for VCT and FFT were 0.25 and 0.75, respectively. Conclusions: VCT has a similar educational benefit to FFT and is a suitable modality of high-quality surgical skills education. VCT provides greater accessibility and resource efficiency compared to FFT. VCT satisfies the requirement for social distancing during the COVID-19 pandemic and is better than non-interactive CBL. VCT has the potential to improve global availability and accessibility of surgical skills training.
ABSTRACT
Introduction: High costs and inaccessibility are significant barriers to face-to-face basic surgical skills (BSS) training. Virtual classrooms enable the combination of computer-based learning with interactive expert instruction. They may optimise resources and increase accessibility, facilitating larger-scale training with a similar educational benefit. We aim to evaluate the efficacy of virtual BSS classroom training compared to both non-interactive video and face-to-face teaching. Method: 72 medical students will be randomly assigned to three equal intervention groups based on year group and surgical skill confidence. Interventions will be implemented following an instructional video. Group A will practice independently, Group B will receive face-to-face training, and Group C will attend a virtual classroom. Participants will be recorded placing three interrupted sutures with hand tied knots preand post-intervention, and Objective Structured Assessment of Technical Skills (OSATS) will be blind marked by two experts. Change in confidence, time to completion and a granular performance score will also be measured. Each intervention's feasibility and accessibility will be assessed. Results: Data collection will be completed in January 2021. Significant improvement in OSATS within groups will be indicative of intervention quality. Difference in improvement between groups will determine the relative performance of the interventions. Conclusions: To our knowledge, this will be the largest randomised control trial investigating virtual BSS classroom training. It will serve as a comprehensive appraisal of the virtual classroom's suitability as an alternative to face-to-face training. The findings will assist the development and implementation of further resource-efficient training programs during the COVID-19 pandemic and in the future.
ABSTRACT
Introduction: High costs and inaccessibility are significant barriers to face-to-face basic surgical skills (BSS) training. Virtual classrooms enable the combination of computer-based learning with interactive expert instruction and feedback. They may optimise resources and increase accessibility, facilitating larger-scale training whilst producing a similar educational benefit. We aim to evaluate the efficacy of virtual BSS classroom training compared to both non-interactive video and face-to-face teaching. Method: 72 medical students will be randomly assigned to three equal intervention groups based on year group and surgical skill confidence. Interventions will be implemented following an instructional video. Group A will practice independently, Group B will receive face-to-face training, and Group C will receive virtual classroom training. The assessed task will be to place three interrupted sutures with hand tied knots. Pre-and post-intervention Objective Structured Assessment of Technical Skills (OSATS) will be blind marked by two experts. Change in confidence, time to completion and a granular performance score will be measured. Feasibility and accessibility will also be assessed. Results: Significant improvement in OSATS within groups will be indicative of intervention quality. Difference in improvement between groups will determine relative performance. Conclusion: To our knowledge, this will be the largest randomised control trial investigating virtual BSS classroom training. It will serve as a comprehensive appraisal of the suitability of virtual BSS classroom training as an alternative to face-to-face training. The findings will assist the development and implementation of further resource-efficient virtual BSS training programs during the COVID-19 pandemic and in the future.
