Detailed Description
Approximately 50% of pediatric patients experience elevated anxiety and distress prior to new medical procedures. This issue is critically important because it not only impacts patient experience and is associated with psychological and physiological distress, but it can affect the efficiency of medical procedures, length of hospital stay, and resource utilization - all of which have economic impacts to both families and the health system. During medical procedures specifically, anxiety can cause non-compliance or unintentional movements which often leads to failure to complete the procedure or poor image quality, necessitating multiple attempts or the use of sedation to achieve the desired quality of imaging for diagnosis.
The impact of sedating a patient has several downstream effects, including the increased potential for adverse events, as well as the need for specialized clinical staff (i.e. Anesthesiologists, Post-Anesthetic Care Nurses, etc), medications, and lengthier post-procedural monitoring. Studies have also indicated an increase in negative post-procedural clinical outcomes, such as increase pain perception, increased pharmaceutical consumption, reductions in sleep and eating, anxiety, and greater overall patient dissatisfaction.
Child Life Specialists (CLS) are specialty trained individuals that work with patients and families to improve patient experiences during stress provoking medical procedures, such as medical imaging. Procedural preparation with a CLS for MRI involves exposure to an MRI simulator. The MRI simulator appears and sounds identical to the real MRI, but lacks a magnet and thus functionality to take real images. It's suggested that this type of non-sedated preparation program can reduce anxiety and distress, ultimately reducing sedation rates.
While access to preparation programs with the CLS have improved, capacity limitations exist and there are socioeconomic costs of only having this support available on-site at BC Children's Hospital. Transportation barriers have been repeatedly identified in the literature and by parents as a source of unmet health needs for children in both rural and inner-city populations. This is significant because it a caregiver cannot get their child to the MRI simulator, they miss the opportunity for a non-sedated MRI. Consequently, resources and the risk for complications increase. As such, a virtual reality program has the capacity to increase access to patients who live afar, who are not mobile, and who need extra practice without the financial and physical limitations associated with the traditional hospital simulation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Virtual Reality
In this arm, participants will receive 45 minutes of preparation using a simulated virtual reality experience designed in collaboration with Medical Imaging and Child Life Specialists.
|
The VR intervention is underpinned by experiential learning and social cognitive theory, such that user will observe successful performance and simulation to encourage imitation and reinforce success in the assessment.
All participants will be undergoing a simulation assessment with the head coil.
|
Active Comparator: Mock MRI
In this arm, participants will receive 45 minutes of preparation using the standard of care simulator, conducted by a Child Life Specialist
|
The mock MRI is provided by the Child Life Specialist, according to the current care plan which consists of exposing children to the MRI simulator, medical devices, and procedures.
The mock MRI is located within the medical imaging facility.
All participants will be undergoing a simulation assessment with the head coil.
Other Names:
|
Active Comparator: Booklet
In this arm, participants will receive 45 minutes of preparation using the standard of care MRI Preparation Booklet for non-sedated MRIs.
|
The standard MRI preparation booklet provides access to a series of printed photos and text showing the MRI experience step-by-step to help prepare for MRI.
All participants will be undergoing a simulation assessment with the head coil.

Length of Stay
Time Frame: 2 hours (max)
|
Length of stay is defined as the duration, in minutes, from starting the preparation segment to completion of the simulated assessment.
Inter-segment times will also be reported.
Preparation time is capped at 45 minutes.
Assessment time is capped at 20 minutes.

Child Perceived Usability
Time Frame: 10 minutes
|
The Smileyometer will be used to measure the opinions of the preparation programs in children.
This will be supplemented with several open-ended questions on the preparation materials according to criteria of fun, ease of use, and how good it was for learning about the MRI experience.

|
Parental Usability
Time Frame: 10 minutes
|
The Usefulness, Satisfaction, Ease of Use (USE) questionnaire will be used to compare the VR application to the simulated MRI experience and will include assessments of usefulness, ease-of-use, ease-of-learning, and satisfaction.
