About

This study will assess the impact of virtual reality (VR) in decreasing procedural pain related to subcutaneous port (SCP) access in children with cancer. The study is a pilot-randomized controlled trial (RCT) using a cross-over design that will provide us with detailed information on the feasibility of implementing our trial protocol in a future multi-center RCT as well as preliminary estimate of VR treatment effect on children with cancer undergoing SCP access, including child and parent factors potentially associated with VR distraction treatment efficacy.

Full description

The study is a repeated-measures cross-over pilot RCT to examine the feasibility of the trial protocol for a study into the effectiveness of immersive VR in minimizing procedural pain and distress in children with cancer. The research objectives are to: (1) pilot implementing immersive virtual reality (VR) for effectiveness testing in a future RCT (measured as implementation outcomes); (2) determine treatment effect sizes (measured as preliminary effectiveness outcomes), between VR, programmed to distract children during an SCP needle insertion, and an active control intervention (i.e., watching a video with headphones); and (3) assess impact of child and parent factors potentially associated with VR treatment effectiveness. Both the intervention and control groups will receive standard medical care (e.g., topical anesthetics). A convenience sample of 40 children and adolescents with cancer (20 participants per treatment arm; 10 boys and 10 girls per treatment arm) will be recruited. In addition, each child will act as their own control. A washout period of 1 month will be used to control for any carry-over effect between conditions. In addition to usual care, children in the experimental condition will wear the VR headset plus headphones. In the control condition, children will watch a video (i.e., an age-appropriate video selected by an oncology-affiliated child life specialist) on an iPad, while wearing the same headphones as in the experimental condition. Implementation outcomes include accrual and retention rates, acceptability and technical difficulties. Effectiveness outcomes include child pain, distress, and fear, as well as parent distress.

Enrollment: 40 patients

Sex: All

Ages: 8 to 18 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Child and parent able to speak and understand English
• actively undergoing cancer treatment
• being less than 1 year from initial diagnosis
• requiring at least 2 SCP needle insertions for cancer treatment over the following 8 weeks

Exclusion criteria

• visual, auditory or cognitive impairments precluding interaction with the intervention or control equipment
• patients with major co-morbid medical or psychiatric conditions (including needle-phobia_ as per their healthcare provider or parent
• end of life patients
• patients with a MRSA infection or symptoms of respiratory or gastrointestinal infection as per any member of their healthcare team which could contaminate the intervention or control equipment
• participation in usability study

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Single Blind

---

40 participants in 2 patient groups

Intervention Group

Experimental group

Description:

In addition to usual care, the intervention group will receive the Samsung GearVR with head mounted display (HMD), controller, and headphones. They will situated in front of the nurse and beside/on the lap of the parent, or they may be lying supine. The VR intervention will use auditory and visual stimuli (simulating the peaceful underwater environment) to distract the child before, during, and after the SCP needle insertion. Children will be allowed to 'try-out' the VR system before the SCP access to familiarize themselves with the equipment. The entire study will be videotaped.

Treatment:

Device: Samsung GearVR

Control Group

Active Comparator group

Description:

In addition to usual care, participants in the control group will be seated with their parent and in front of the nurse, according to preference. Children will watch an age appropriate video selected by an oncology-affiliated child life specialist on an iPad, while wearing the same headphones used in the experimental condition. The RA will hold the iPad and positioned within a meter of the child so that the child can still see the iPad without the RA interfering in the clinical procedure. The entire study will be videotaped.

Treatment:

Device: iPad
