Abstract
Virtual reality (VR), which offers an immersive experience, has been implemented into the education of pediatric patients to reduce peri-procedural anxiety. This randomized clinical trial evaluated the effect of VR, compared with standard video, on reducing anxiety and distress in pediatric patients undergoing chest radiography. A total of 120 children aged 4 to 8 years with scheduled chest radiography appointments were randomized into either the tablet or the VR group. Children in the tablet group experienced chest radiography indirectly with a 3 min tablet video, whereas those in the VR group received the same content via a VR experience. The distress of children was measured using the Observational Scale of Behavioral Distress (OSBD) scale. Parental presence and procedural outcomes were also recorded. The number of less distressed children (OSBD score < 5) was significantly higher in the VR group than in the tablet group (49 [81.7%]) vs. 32 [53.3%]) (p = 0.001). The OSBD scores, the need for parental presence, the procedure time, and the number of repeated procedures were all lower in the VR group. The immersive VR experience appears to decrease the degree of anxiety in children and increase the efficiency of the procedures compared with the tablet video with the same content.
