Use of 360° virtual reality video in medical obstetrical education: a quasi-experimental design

Abstract

Background: Video-based teaching has been part of medical education for some time but 360° videos using a virtual reality (VR) device are a new medium that offer extended possibilities. We investigated whether adding a 360° VR video to the internship curriculum leads to an improvement of long-term recall of specific knowledge on a gentle Caesarean Sections (gCS) and on general obstetric knowledge. Methods: Two weeks prior to their Obstetrics and Gynaecology (O&G) internship, medical students were divided in teaching groups, that did or did not have access to a VR-video of a gCS. Six weeks after their O&G internship, potentially having observed one or multiple real-life CSs, knowledge on the gCS was assessed with an open questionnaire, and knowledge on general obstetrics with a multiple-choice questionnaire. Furthermore we assessed experienced anxiety during in-person attendance of CSs, and we asked whether the interns would have wanted to attend more CSs in-person. The 360° VR video group was questioned about their experience directly after they watched the video. We used linear regression analyses to determine significant effects on outcomes. Results: A total of 89 medical students participated, 41 in the 360° VR video group and 48 in the conventional study group. Watching the 360° VR video did not result in a difference in either specific or general knowledge retention between the intervention group and the conventional study group. This was both true for the grade received for the internship, the open-ended questions as well as the multiple-choice questions and this did not change after adjustment for confounding factors. Still, 83.4% of the 360° VR video-group reported that more videos should be used in training to prepare for surgical procedures. In the 360° VR video-group 56.7% reported side effects like nausea or dizziness. After adjustment for the number of attended CSs during the practical internship, students in the 360° VR video-group stated less often (p = 0.04) that they would have liked to attend more CSs in-person as compared to the conventional study group. Conclusion: Even though the use of 360° VR video did not increase knowledge, it did offer a potential alternative for attending a CS in-person and a new way to prepare the students for their first operating room experiences.
