Abstract

BACKGROUND

Traditional face-to-face training (FFT) for basic surgical skills is inaccessible and resource-intensive. Noninteractive computer-based learning is more economical but less educationally beneficial. Virtual classroom training (VCT) is a novel method that permits distanced interactive expert instruction. VCT may optimize resources and increase accessibility.

OBJECTIVE

We aim to investigate whether VCT is superior to computer-based learning and noninferior to FFT in improving proficiency in basic surgical skills.

METHODS

This is a protocol for a parallel-group, noninferiority, randomized controlled trial. A sample of 72 undergraduates will be recruited from 5 medical schools in London. Participants will be stratified by subjective and objective suturing experience level and allocated to 3 intervention groups at a 1:1:1 ratio. VCT will be delivered using the BARCO weConnect software, and FFT will be provided by expert instructors. Optimal student-to-teacher ratios of 12:1 for VCT and 4:1 for FFT will be maintained. The assessed task will be interrupted suturing with hand-tied knots.

RESULTS

The primary outcome will be the postintervention Objective Structured Assessment of Technical Skills score, adjudicated by 2 experts blinded to the study and adjusted for baseline proficiency. The noninferiority margin (δ) will be defined using historical data.

CONCLUSIONS

This study will serve as a comprehensive appraisal of the suitability of virtual basic surgical skills classroom training as an alternative to FFT. Our findings will assist the development and implementation of further resource-efficient, accessible, virtual basic surgical skills training programs during the COVID-19 pandemic and in the future.

摘要

背景

传统的面对面基本外科技能培训难以实现且资源密集。非交互式计算机辅助学习成本更低，但教育效益较差。虚拟课堂培训（VCT）是一种新型方法，可实现远程交互式专家指导。VCT可能会优化资源并提高可及性。

目的

我们旨在研究在提高基本外科技能熟练度方面，VCT是否优于计算机辅助学习且不劣于面对面培训（FFT）。

方法

这是一项平行组、非劣效性随机对照试验方案。将从伦敦的5所医学院招募72名本科生作为样本。参与者将根据主观和客观缝合经验水平进行分层，并以1:1:1的比例分配到3个干预组。VCT将使用巴可weConnect软件进行授课，FFT将由专家教员提供。VCT的最佳师生比为12:1，FFT为4:1。评估任务将是用手打结进行间断缝合。
