Virtual Reality Distraction for Procedural Pain Management in Children With Burn Injuries: a Randomized Controlled Trial

Pain Clinical Trial

Official title: Virtual Reality Distraction for Procedural Pain Management in Children With Burn Injuries: a Randomized Controlled Trial

Status Completed

Clinical Trial Summary

Procedural pain is the most intense and often undertreated pain associated with burn injuries. The use of analgesics does not always provide optimal relief and is accompanied by several side effects. Indeed, children with burn injuries still experience severe pain intensity during procedures despite the fact that doses of analgesics used with this population has almost doubled in the last twenty years. Current guidelines on pediatric procedural pain management recommend the combination of non-pharmacological and pharmacological interventions to enhance pain management and decrease the numerous side effects of analgesics. Distraction has been identified among the most effective non-pharmacological interventions for pain as it diverts the child's attention to an attractive element, hindering the perception of the painful stimuli. Virtual reality is a method of active distraction that offers the child a multi-sensory immersive interaction that found many applications for pain management in adult patients. However, very few studies have tested the efficacy of distraction by virtual reality on procedural pain and anxiety in children with burn injuries.

This RCT follows a pilot study (NCT02794103) aimed at assessing the feasibility of a virtual reality prototype developed specifically for the hydrotherapy room of children under seven years old for the relief of procedural pain in children with burn injuries. The aim of the RCT will be to evaluate the effectiveness of the virtual reality prototype in relieving procedural pain in children from 6 months to 7 years old undergoing hydrotherapy session for burn injuries.

Clinical Trial Description

BACKGROUND:

Preliminary data from the pilot study showed that the virtual reality prototype installed around the tank in the hydrotherapy room is a feasible and acceptable method of distraction that doesn't interfere with the work of healthcare professionals and could be used as a non-pharmacological method for pain management. A clinical trial is needed to assess the effectiveness of this intervention for procedural pain relief. The pilot study was also informative about the feasibility of the study design and the measurement used. The methods section was modified and adapted consequently for the upcoming trial.

METHODS:

Design: Within-subject/crossover study design. Each child will serve as their own control and will receive both standard and experimental treatment during the same hydrotherapy session through a randomized order.

Sample and Setting: Convenience sampling on the surgical-trauma burn unit at CHU Ste-Justine, of children admitted to the unit or to the day hospital for a burn injury. The intervention will take place in the hydrotherapy room of the CHU Ste-Justine.

Interventions. A) Standard pharmacological treatment as per the unit's protocol. B) VR distraction through the use of a virtual reality prototype installed around the tank in the hydrotherapy room. The prototype has been developed in collaboration with the Society of Arts and Technology (SAT) in Montreal to provide an immersive interactive experience for the burn child in the hydrotherapy tank. The prototype was developed after several meetings between the researchers, the designers and engineers and the surgical trauma team of CHU Ste-Justine. Meetings were followed by an ergonomic study of the hydrotherapy room to meet the unit's and patients' specifications and ensure that it doesn't interfere with the healthcare professionals work.The video games were developed by our team with a personalized care content tailored to the children's developmental stage and to maximize the feeling of immersion and minimize cybersickness, and approved by a team of healthcare professionals in pediatric burn care.

Study proceedings: Hydrotherapy sessions typically last between 20 to 40 minutes. The duration will be divided into two sequences of the same duration (10 to 20 minutes) where the participant receives the same care by the same healthcare professional. For one sequence, only the standard treatment will be administered and for the other sequence, patients will receive the standard treatment in addition to Virtual Reality via the screen around the tank in a randomized order.

Measures: Pain and anxiety measures will be taken before the treatment session at Baseline (T1), in the middle of the first sequence of the session (T2) and in the middle of the second sequence of the session (T3) followed by a measure of healthcare professionals` satisfaction level via a questionnaire developed and pretested by the team after the session (T4). Data will be collected on the average doses of analgesics administered before and during the session, and the side effects experienced.

Data analysis: Quantitative analysis. Mean differences in pain scores between sequences will be compared using Wilcoxon test. ;
