Learning in 360 Degrees: A Pilot Study on the Use of Virtual Reality for Radiation Therapy Patient Education

Background: Patient education for external beam radiation therapy (EBRT) is traditionally delivered in verbal and/or written form, which may not provide a full picture of the complex, technical aspects of treatment. The purpose of this pilot study was to create and evaluate a prototype 360-degree virtual reality (VR) video outlining the technical aspects of EBRT to the pelvis as a supplement to traditional education methods. Materials and Methods: A prototype VR video was filmed to simulate the delivery of one fraction of image-guided EBRT to the pelvis. Patients having a radical course of image-guided EBRT to the pelvis were approached while on active treatment to participate in focus groups evaluating the prototype VR video. Focus group discussions were recorded, transcribed, and subjected to thematic analysis. Results: All patients were accrued from a single academic cancer centre in a large metropolitan area. In total, seven patients were enrolled to participate in the focus groups. Thematic analysis revealed 71% of participants felt the traditional patient education met their needs. However, 86% mentioned the education did not fully capture the treatment experience. Participants identified potential benefits of VR could include an increased understanding of the treatment process, specifically the spatial and acoustic aspects of treatment, as well as the potential to reduce anxiety in new patients. Timing was also important, with 86% of participants recommending VR video viewing before the first day of treatment. Participants provided feedback such as including two-dimensional elements in the VR video and other changes which could potentially make the viewing experience more realistic. Conclusions: Traditional teaching methods are seen as satisfactory by patients at our institution, but it is recognized that there is a gap in current education methods. An immersive VR education tool has the potential to enhance standard patient education, increasing understanding of treatment and decreasing anxiety.
