ABSTRACT

Background:

The hospital experience is often marked by fear and pain, particularly for children undergoing medical procedures. Sedation is commonly used to alleviate patient anxiety, but it poses additional health risks. Caregivers, usually the parents, also experience emotional distress during the child's hospital stay, which can further exacerbate the child's anxiety and pain. While various interventions exist to ease patient distress, few consider the emotional well-being of caregivers.

Objective:

This study aims to explore the effectiveness of a cooperative virtual reality (VR) game as a novel non-pharmacological solution to reduce anxiety and pain for both pediatric patients and their caregivers during medical procedures. Specifically, we investigate whether the VR game "Sweet Dive VR" (SDVR), designed for children aged 6-12 years to play with one caregiver, can alleviate anxiety and pain during different types of needle punctures and Kirschner-wire removal.

Methods:

A prospective multicenter randomized clinical trial is conducted. Eligible participants are identified by scanning the hospital information system, and group allocation follows stratified randomization. During the medical procedure, patients in the VR condition play SDVR with a caregiver present, while patients in the control group listen to a recording of gently crashing waves. Data collection will be carried out through self-reports of patients and caregivers using visual analog scales and questionnaires at two measurement time points: pre- and post-intervention. Additionally, observation by the interviewers occurs during the intervention to capture emotional and pain reactions as well as interaction quality between patients and caregivers and smoothness of the procedure flow using a structured observation protocol. The measured variables encompass patient affect and pain, caregiver affect, player experience, patient experience, and the flow of the procedure.

Results:

The study results are expected to be published in March 2025.

Conclusions:

Cooperative VR gaming, as exemplified by SDVR, emerges as a promising intervention to address anxiety and pain in pediatric patients while involving caregivers to support the emotional well-being of both parties. Our approach strives to foster positive shared experiences and to maintain trust between children and caregivers during emotionally challenging medical situations.
