HMD-Based Virtual and Augmented Reality in Medical Education: A Systematic Review

Abstract

Background: Virtual Reality (VR) and Augmented Reality (AR) technologies provide a novel experiential learning environment that can revolutionize medical education. These technologies have limitless potential as they provide in effect an infinite number of anatomical models to aid in foundational medical education. The 3D teaching models used within these environments are generated from medical data such as magnetic resonance imaging (MRI) or computed tomography (CT), which can be dissected and regenerated without limitations.Methods: A systematic review was carried out for existing articles until February 11, 2020, in EMBASE, PubMed, Scopus, ProQuest, Cochrane Reviews, CNKI, and OneSearch (University College Dublin Library) using the following search terms: (Virtual Reality OR Augmented Reality OR mixed reality) AND [“head-mounted” OR “face-mounted” OR “helmet-mounted” OR “head-worn” OR oculus OR vive OR HTC OR hololens OR “smart glasses” OR headset AND (training OR teaching OR education)] AND (anatomy OR anatomical OR medicine OR medical OR clinic OR clinical OR surgery OR surgeon OR surgical) AND (trial OR experiment OR study OR randomized OR randomised OR controlled OR control) NOT (rehabilitation OR recovery OR treatment) NOT (“systematic review” OR “review of literature” OR “literature review”). PRISMA guidelines were adhered to in reporting the results. All studies that examined people who are or were medical-related (novel or expert users) were included.Result: The electronic searches generated a total of 1,241 studies. After removing duplicates, 848 remained. Of those, 801 studies were excluded because the studies did not meet the criteria after reviewing the abstract. The full text of the remaining 47 studies was reviewed. After applying inclusion criteria and exclusion criteria, a total of 17 studies (1,050 participants) were identified for inclusion in the review.Conclusion: The systematic review provides the current state of the art on head-mounted device applications in medical education. Moreover, the study discusses trends toward the future and directions for further research in head-mounted VR and AR for medical education.
