VR Based Simulation in the Preparation of Children for MRI - MRVR

Efficacy of Virtual Reality Based Simulation in the Preparation of Children for Magnetic Resonance Imaging Examinations: a Randomized Clinical Trial (MRVR)

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 288 (estimated)
• Sponsor: Semmelweis University · Academic / Other
• Sex: All
• Age: 4 Years – 18 Years
• Healthy volunteers: Not accepted

Summary

The goal of this randomized controlled trial is to evaluate whether a virtual reality based preparation method can efficiently decrease the proportion of children requiring general anesthesia during MRI examinations. Participants will take part in a virtual reality environment resembling an MRI before their scheduled MRI examination. Researchers will compare these children to usual care and a booklet based preparation method to see if less children need anesthesia for completing the MRI examination.

Detailed description

Study Description: Our study investigates the efficacy of a custom-made virtual reality experience in the preparation of children for MRI examinations. We hypothesise that preparation with VR can significantly reduce the need for anesthesia in children during MRI examinations, or if anesthesia is needed less doses of anesthetics are required. Objectives: Primary Objective: To evaluate whether the VR based preparation decreases the need for anesthesia and sedation during MRI examinations. Secondary Objectives: To evaluate whether fear, mood, anxiety, familiarity with the MRI examination of the children and willingness to take part again change as a result of the intervention. Endpoints: Primary Endpoint: The need for any anesthetic or sedative medication during MRI examination. Secondary Endpoints: Visual analogue scales related to fear, mood and familiarity, willingness to take part in an MRI examination again. Study Population: 288 children aged 4-18 years who are in- or outpatients at the Pediatric Center of the Semmelweis University and are scheduled for MRI examination with anesthesia will be enrolled. Description of Sites/Facilities Enrolling Participants: The study takes place in the two Departments of the Pediatric Centre of the Semmelweis University Description of Study Intervention/Experimental Manipulation: Our research will be conducted as a three arm randomized controlled trial (VR, booklet, usual care). Participants in the VR condition are immersed in a unique 360° VR experience specifically designed for this study. Children in the booklet condition will be prepared by using an educational booklet containing colorful illustrations about the MRI examination. In the usual care condition children are prepared by the healthcare staff without using any specific equipment or standardized methods. Study Duration: 36 months Participant Duration: All participants need a single visit intervention to complete all study related tasks.
