Student perceptions of the use of three-dimensional (3-D) virtual reality (VR) simulation in the delivery of radiation protection training for radiography and medical students

Abstract

BackgroundVR simulation-based learning is increasingly used in healthcare education to prepare students for clinical practice. This study investigates healthcare students' experience of learning radiation safety in a simulated interventional radiology (IR) suite. MethodRadiography students (n = 35) and medical students (n = 100) were introduced to 3D VR radiation dosimetry software designed to improve the learners' understanding of radiation safety in IR. Radiography students underwent formal VR training and assessment, which was complemented with clinical placement. Medical students practiced similar 3D VR activities informally without assessment. An online questionnaire containing Likert questions and open-ended questions was used to gather student feedback on the perceived value of VR-based radiation safety education. Descriptive statistics and Mann–Whitney U tests were used to analyse Likert-questions. Open-ended question responses were thematically analysed. ResultsA survey response rate of 49% (n = 49) and 77% (n = 27) was obtained from radiography and medical students respectively. Most respondents (80%) enjoyed their 3D VR learning experience, favouring the in-person VR experience to online VR. 73% felt that VR learning enhanced their confidence across all relevant learning outcomes. Whilst confidence was enhanced across both cohorts, VR learning had a greater impact on confidence levels amongst medical students with respect to their understanding of radiation safety matters (U = 375.5, p < 0.01). 3D VR was deemed a valuable assessment tool. ConclusionRadiation dosimetry simulation-based learning in the 3D VR IR suite is perceived to be a valuable pedagogical tool by radiography and medical students and enhances curricula content.
