Background: Educational videos are a potent resource for the learning of surgical skills among different study cohorts. However, there is limited evidence on the effectiveness of different educational video interventions and their features. Methods : A systematic search of MEDLINE (via PubMed), Embase (via OVID), Cochrane libraries and Clinicaltrials.gov was performed from inception to 28/02/21. Studies included were not limited by date of publication, studies aiming to assess the impact of video-based interventions in the direct acquisition of surgical skill were included. Eligible studies were analysed based on study type, type of video intervention, method of assessment and period of education. The educational impact of the studies was also assessed as per Messick’s framework for testing validity of evaluation methods and McGhagie’s model for analysing translational outcomes. Results : 22 studies were deemed suitable for inclusion, of which 14/22 (63.6%) demonstrated a significant improvement in knowledge/skills following the video-based teaching interventions, 3/22 (13.6%) studies demonstrated an improvement in trainee satisfaction scores. A recurrent limitation of the included studies was the lack of validation of selected assessment methods. None of the included studies scored on all 5 parameters of validity as defined by Messicks validity framework. Furthermore, none of the included trials were conducted for long enough to indicate direct changes to patient outcomes resultant from educational methods. Conclusion: Video-based surgical education is effective in learning surgical skills within different levels of surgical training; however, superior study quality and follow-up is required to determine which aspects of video-based interventions are most impactful.
