Virtual Reality for Hemophilia

A Feasibility and Usability Study of a Nursing Orchestrated, Customized 3 Dimensional Virtual Reality Environment in Children With Hemophilia Undergoing Routine Intravenous Procedures

Children with hemophilia are exposed to intravenous (IV) procedures that cause pain/anxiety and distraction methods can be employed to improve the patient experience. Three-dimensional virtual reality (VR) environments can reduce distress related to procedures. To be utilized in a clinical setting, however, these devices must address infection control concerns and fit pediatric patients. Additionally, for use in hemophilia care, environments should encourage a subject to keep their hands/arms still to facilitate procedures. Nursing orchestration of the VR environment via an iPad dashboard has the potential to increase feasibility and acceptance by patients, families and providers of the VR experience without disrupting routine clinical care.

Study Overview

• Status: Completed
• Conditions: Hemophilia A; Hemophilia B
• Intervention / Treatment: Other: Virtual Reality Distraction; Other: Standard of Care Distraction

Detailed Description

Patients with hemophilia A and B (HA/HB) are frequently treated with IV infusions of clotting factor concentrates to treat and prevent bleeding. Additionally they typically have at least yearly IV laboratory assessments. Pain and anxiety with needle related procedures particularly in children with hemophilia can lead to development of needle phobia, treatment avoidance and poor adherence to treatment regimens. Conventional virtual reality (VR) environments have been shown to reduce pain/anxiety in pediatric populations however in a clinical setting children with hemophilia have specific VR design needs that have not been addressed. Certain issues related to VR environments are related to the pediatric age range. These include the size and weight of VR headsets, the ease of donning and doffing headsets, and degree of engagement with VR environments. Hemophilia specific issues include the need for the VR experience to limit movement of the hands/arms to facilitate IV procedures, customization to prevent boredom/disengagement from repeated use and ability of clinical staff to trigger events via an orchestration dashboard that occur for the patients benefit at key times during IV procedures. Lastly, there are issues related to integration into a clinical setting. These include ability to integrate into clinical care without adversely affecting clinic flow, and infection control issues related to headset design.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Virtual Reality Distraction; This intervention consists of a disposable virtual reality headset which will enable the use of virtual reality in clinic through the commodity hardware iPod Touch. An additional piece of software on an iPad will allow clinical staff to act as an orchestrator and trigger events that occur for the patient's benefit in the virtual reality environment. The mechanism for the dashboard will be dashboard software running on an iPad tablet that will wirelessly communicate to the iPod Touch the patient is wearing. A study timer will be incorporated into the orchestration dashboard. The VAS/FACES scale will be incorporated into the iPad used for orchestration.

Active Comparator: Standard of Care Distraction; This intervention consists of a two dimensional distraction (ie TV/tablet) as well as verbal distraction (ie singing/talking/music) will be allowed by caregivers, nurses and phlebotomy staff but will not qualified or quantified. IV procedures will proceed in Groups A and B. At the completion of the IV procedure the nurse orchestrator will stop the procedure timer. The Subject, Guardian and Nurse orchestrator will complete the Final VAS/FACES assessment on the iPad.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Nurse Orchestrated Virtual Reality Distraction	The primary outcome of feasibility was assessed using a surrogate marker of feasibility which was duration of the IV procedure measured in minutes in both study arms. Procedure time was the length of time from the moment a patient was positioned for the procedure to the completion of the procedure. The study timer was incorporated in the study IPAD and timing was performed by the nurse orchestrator.	Twelve months
Standard of Care Distraction	The primary outcome of feasibility was assessed using a surrogate marker of feasibility which was duration of the IV procedure measured in minutes in both study arms. Procedure time was the length of time from the moment a patient was positioned for the procedure to the completion of the procedure. The study timer was incorporated in the study IPAD and timing was performed by the nurse orchestrator.	Twelve months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Effectiveness of the distraction technique	Both patient groups assessed the effectiveness of their distraction techniques following the procedure by using a Visual analogue/FACES scale answering 3 anchored questions. 1) "Did the distraction technique keep you/your child /your patient engaged?" The anchors were 0=It really kept them engaged and 100=It really did not keep them engaged. 2) "Do you think the distraction technique/s changed you/your child/your patient's nervousness/anxiety level during the IV procedure?" The anchor of 0=it decreased nervousness/anxiety a lot, 100=it increased nervousness/anxiety a lot. 3) "How did the distraction technique/s affect pain during your/your child/your patient's IV procedure?" With 0=it made pain a lot better, 100=it made pain a lot worse.	Twelve months
Usability and Likeability	For patients randomized to the VR arm, data on the use of the VR equipment was recorded by the nurse orchestrator at the end of each procedure. Data was categorized if the participant wore the VR equipment: 1) during the entire procedure, 2) part of the procedure or 3) only prior to the procedure. Participants were also asked to rate usability of the VR equipment, by using the VAS/FACES scale to answer "How easy was it for you/your child/your patient to use the VR equipment?" A score of 0 represented really easy to use and a score of 100 correlated with really hard to use. Lastly, participants were asked to use the VAS?FACES scale to answer a likeability question by "How much would you/your child/your patient like to use VR for future IV procedures?" A score of 0 equated to they would really like to use VR again and 100 meant they would really not like to use it again.	Twelve months
