Validity and effectiveness of augmented reality in surgical education: A systematic review

Background: Current challenges in surgical training have led to the investigation of augmented reality as a potential method of supplementary education. However, its value for this purpose remains uncertain. The aim of this study was to perform a systematic review of the published literature to evaluate the validity and effectiveness of augmented reality in surgical education, and to compare it with other simulation modalities. Methods: Electronic literature searches were performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Two authors independently extracted pertinent data and assessed study quality. The primary outcome measures of interest were the validity and effectiveness of augmented reality as an educational tool. Results: Of 6,500 articles, 24 studies met eligibility criteria for inclusion, of which 2 were randomized. Ten studies investigated validity, with 7 establishing both face and content validity and an additional 1 just content validity. Construct validity was demonstrated in 9 of 11 studies. Of the 11 studies that examined the effectiveness of augmented reality in skills acquisition, 9 demonstrated enhanced learning. Of the 5 studies in which the effectiveness of augmented reality as an educational tool was compared with other modes of simulation, augmented reality was found to be superior in 2 and equivalent in the others. Conclusion: Overall, the majority, including 2 high-quality randomized controlled trials, demonstrated the validity and effectiveness of augmented reality in surgical education. However, the quality of published studies was poor with marked heterogeneity. Although these results are encouraging, additional high-quality studies, preferably in the real-life environment, are required before the widespread implementation of augmented reality within surgical curricula can be recommended.

Automated summary

This systematic review evaluated the validity and effectiveness of augmented reality in surgical education, showing that most studies demonstrated enhanced learning in skills acquisition. However, the quality of published studies varied, warranting the need for more high-quality research before widespread implementation.
