A Novel Clinician-Orchestrated Virtual Reality Platform for Distraction During Pediatric Intravenous Procedures in Children With Hemophilia: Randomized Controlled Trial

Abstract

BackgroundNeedles are frequently required for routine medical procedures. Children with severe hemophilia require intensive intravenous (IV) therapy to treat and prevent life-threatening bleeding and undergo hundreds of IV procedures. Fear of needle-related procedures may lead to avoidance of future health care and poor clinical outcomes. Virtual reality (VR) is a promising distraction technique during procedures, but barriers to commercially available VR platforms for pediatric health care purposes have prevented widespread use.ObjectiveWe hypothesized that we could create a VR platform that would be used for pediatric hemophilia care, allow clinician orchestration, and be safe and feasible to use for distraction during IV procedures performed as part of complex health care.MethodsWe created a VR platform comprising wireless, adjustable, disposable headsets and a suite of remotely orchestrated VR games. The platform was customized for a pediatric hemophilia population that required hands-free navigation to allow access to a child’s hands or arms for procedures. A hemophilia nurse observing the procedure performed orchestration. The primary endpoint of the trial was safety. Preliminary feasibility and usability of the platform were assessed in a single-center, randomized clinical trial from June to December 2016. Participants were children with hemophilia aged 6-18 years. After obtaining informed consent, 25 patients were enrolled and randomized. Each subject, 1 caregiver, and 1 hemophilia nurse orchestrator assessed the degree of preprocedural nervousness or anxiety with an anchored, combined modified visual analog (VAS)/FACES scale. Each participant then underwent a timed IV procedure with either VR or standard of care (SOC) distraction. Each rater assessed the distraction methods using the VAS/FACES scale at the completion of the IV procedure, with questions targeting usability, engagement, impact on procedural anxiety, impact on procedural pain, and likability of the distraction technique. Participants, caregivers, and nurses also rated how much they would like to use VR for future procedures. To compare the length of procedure time between the groups, Mann-Whitney test was used.ResultsOf the 25 enrolled children, 24 were included in the primary analysis. No safety concerns or VR sickness occurred. The median procedure time was 10 (range 1-31) minutes in the VR group and was comparable to 9 (range 3-20) minutes in the SOC group (P=.76). Patients in both the groups reported a positive influence of distraction on procedural anxiety and pain. Overall, in 80% (34/45) of the VR evaluations, children, caregivers, and nurses reported that they would like to use VR for future procedures.ConclusionsWe demonstrated that an orchestrated, VR environment could be developed and safely used during pediatric hemophilia care for distraction during IV interventions. This platform has the potential to improve patient experience during medical procedures.Trial RegistrationClinical Trials.gov NCT03507582; https://clinicaltrials.go...

Virtual reality teaching in chemotherapy administration: Randomised controlled trial

“…Many innovative teaching methods such as videos and animations, help nursing students and has the potential to make cancer drug administration less hazardous. Some of them train the students to avoid high-risk situations and provide them with the opportunity to repeat chemotherapy injection techniques via simulations (Dunn et al, 2019;Khan et al, 2017;Rahimi et al, 2019). For safety and ethical considerations, nurse students usually are not allowed to handle toxic materials.…”

“…The use of virtual reality (VR) has been explored as a novel approach for numerous health applications wherein, threedimensional virtual environments can be explored in real time. VR learning situations can not only minimise the medical negligence caused by clinical technology sparseness but also address the shortcomings of many traditional teachings (Dunn et al, 2019;Schneider & Hood, 2007). However, the question is, will the students gain better knowledge and working attitude after learning?…”

Virtual Reality Interventions for Needle-Related Procedural Pain, Fear and Anxiety—A Systematic Review and Meta-Analysis

“…Finally, one study was excluded as the primary outcomes did not fit the review assumptions. The measured outcomes were safety concerns, effectiveness, usability and engagement of VR during intravenous procedures [ 43 ].…”

The Effect of Three Different Methods on Venipuncture Pain and Anxiety in Children: Distraction Cards, Virtual Reality, and Buzzy® (Randomized Controlled Trial)

“…It reduces pain and anxiety during medical procedures in children, thereby ensuring better adaptation and treatment adherence (Mahrer, 2018). To date, only a handful of randomized controlled trials (RCTs) have investigated the effect of VR on venipuncture/phlebotomy pain management and reported that it helps reduce pain and/or anxiety during venipuncture/phlebotomy procedures (Aminabadi, Erfanparast, Sohrabi, Oskouei, & Naghili, 2012;Chan et al, 2019;Dunn et al, 2019;Gerçeker et al, 2020;Gerçeker, Binay, Bilsin, Kahraman, & Yılmaz, 2018;Mahrer, 2018). According to a systematic review and metaanalysis of the effect of VR on pain and anxiety, although some studies address the effectiveness of VR on pain, there are very few studies examining its effect on anxiety, hence, calling for further research (Eijlers et al, 2019).…”
