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

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Informed assent and parental informed consent to participate in the study.
  • Stated willingness to participate in the intervention and to complete study questionnaires.
  • Inpatient or outpatient at the Pediatric Center.
  • Age 4-18 years
  • Scheduled for MRI examination under anesthesia at the Semmelweis University.
  • Fluent in Hungarian language

Exclusion criteria

  • Severe visual impairment or hearing loss that would hinder the participation of the VR and booklet experience.
  • In case of epilepsy, if the treating physician recommend against participation.
  • Children with severe intellectual disability which would hinder participation in the VR group e.g. not able to follow simple instructions.
  • Inpatients, if the treating physician indicates that the child is too unwell for the study.
  • Face or cranial deformities, wounds on the face and head which would hinder wearing the VR headset.

Treatment and study plan

VR

Other

The virtual environment is provided by the Oculus Quest 2 or 3 VR headset, providing a high-quality and immersive visual experience.

Booklet

Other

Children in the booklet condition will be prepared by using an educational booklet containing colorful illustrations of the MRI examination room and about the procedure.

Primary outcomes

  1. proportion of children requiring anesthesia

    Time frame: during the MRI examination, assessed directly after the MRI from anesthesiology documentation

    proportion of children requiring any form of anesthesia or sedation during the MRI examination

Secondary outcomes

  1. fear

    Time frame: assessed directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    fear of the child measured on a visual analogue scale range 1-100, higher indicating increased fear

  2. mood

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    mood of the child measured on a visual analogue scale, scale range 1-100, higher indicating better mood

  3. nervousness

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    nervousness of the child measured on a visual analogue scale, scale range 1-100, higher increased nervousness

  4. familiarity

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    familiarity of the child with the MRI examination measured on a visual analogue scale scale range 1-100, higher indicating increased familiarity with the MRI

  5. willingness to take part again

    Time frame: no later than 4 hours after the MRI examination

    willingness of the child to take part in a future MRI examination measured on a visual analogue scale, scale range 1-100, higher indicating more willingness taking part in a future MRI examination

  6. helpfulness

    Time frame: directly before the MRI examination

    indication how much the child found the preparation method helpful, measured on a visual analogue scale, scale range 1-100, higher indicating the preparation method was more helpful

Other outcomes

  1. fear of the parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    fear of the parent measured on a visual analogue scale, range 1-100, higher indicating increased fear

  2. mood of the parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    mood of the parent measured on a visual analogue scale, scale range 1-100, higher indicating better mood

  3. nervousness of the parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    nervousness of the parent measured on a visual analogue scale, scale range 1-100, higher increased nervousness

  4. familiarity of the parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    familiarity of the parent with the MRI examination measured on a visual analogue scale, scale range 1-100, higher indicating increased familiarity with the MRI

  5. fear of the child assessed by parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    fear of the child assessed by parent measured on a visual analogue scale, range 1-100, higher indicating increased fear

  6. mood of the child assessed by parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    mood of the child assessed by parent measured on a visual analogue scale, scale range 1-100, higher indicating better mood

  7. nervousness of the child assessed by parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    nervousness of the child assessed by parent measured on a visual analogue scale, scale range 1-100, higher increased nervousness

  8. familiarity of the child assessed by parent

    Time frame: directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination

    familiarity of the child with the MRI examination assessed by parent measured on a visual analogue scale, scale range 1-100, higher indicating increased familiarity with the MRI
