An Affordable Platform for Virtual Reality-Based Patient Education in Radiation Therapy.

PURPOSE

The goal of this study was to develop and assess the effectiveness of an affordable smartphone-based virtual reality (VR) patient education platform with 360-degree videos produced depicting a first-person patient perspective during the radiation therapy (RT) care path to reduce patient anxiety.

METHODS AND MATERIALS

Three disease site-specific (breast, pelvis, head and neck) VR videos were filmed using a 360-degree camera to portray the first-person perspective of a patient's standard RT appointments, including a computed tomography simulation and the first RT treatment session. Instruction is given for possible clinical implementation. Patient participation was divided into 2 groups: (1) Group A (n = 28) included patients participating before simulation and later after the first treatment, and (2) Group B (n = 33) included patients participating only while undergoing treatment. Patients viewed their disease site-specific video using an inexpensive cardboard VR viewer and their smartphone, emulating an expensive VR-headset. Surveys were administered assessing patient anxiety, comfort, satisfaction, and knowledge of RT on a 5-point Likert-type scale.

RESULTS

Patients in Group A and Group B while undergoing treatment both indicated that their anxiety "decreased a little" in the survey, after watching the VR video (Group A, median on a 5-point Likert-type scale, 4 [IQR, 4-5]; Group B, 4 [IQR, 4-4]). The VR aspect of the videos was especially liked by patients while undergoing treatment, with 96.4% in Group A and 90.9% in Group B reporting that the VR aspect of the videos was helpful. All Group A participants believed that the VR videos would be beneficial to new patients.

CONCLUSIONS

Our affordable VR patient education platform effectively immerses a patient in their care path from simulation through initial treatment delivery, reducing anxiety and increasing familiarity with the treatment process.
