Plain English Summary

Background and study aims
Every year a small percentage of patients that are referred for a PET/CT are unable to complete the procedure due to claustrophobia-induced and procedure-related anxiety. As PET/CT involves the use of a radioactive tracer, patients that have the injection but then fail to finish the scan due to anxiety will receive the radiation detriment for no benefit. The project proposed will investigate whether a virtual tour constructed from 360 videos of the PET suite, and procedures that the patient would undergo (Virtual Reality (VR) intervention), displayed on a VR Headset, could be used to reduce patient claustrophobia induced and procedure-related anxiety and improve the patient experience. The VR tour is very much like the virtual tours that estate agents use to showcase properties. This is a pilot study; therefore, the primary aim is to assess the acceptability and feasibility of the VR tour and collect data on anxiety measures for the intervention (VR) and comparator groups. This pilot will inform and appropriately power a larger trial and provide additional information to existing knowledge in the literature.

Who can participate?
Adult patients attending a PET/CT scan

What does the study involve?
Anxiety will be measured using two validated anxiety measures before and once again after the intervention or Comparator. The second measure will be taken before the patient's actual PET/CT scan. Anxious patients that are referred for PET/CT are given the opportunity to see the PET/CT scanner before their scan however this can be difficult to arrange due to clinical workload.

What are the possible benefits and risks of participating?
We are conducting this trial to see if there is a potential benefit in reducing anxiety, with a focus on claustrophobia or anxiety directly regarding the scan. We do not know if the VRtour will reduce a patient’s anxiety, which is why we are doing this study. We hope that the information we get from this study will help us to improve the care of people who are anxious about PET/CT scans.

It is very unlikely that a participant would be harmed by taking part in this research. As the VR tour simulates the PET/CT experience, it is possible that it may make them feel anxious. Motion Sickness from the VR tour is also a possibility, however, the tour has been designed to mitigate this risk and include mostly static viewpoints.

Scientific titlePilot study on the use of a Virtual Reality Tour to reduce anxiety in patients referred for PET/CT scans
Study acronymPET-CT VR Tour
Study hypothesisA virtual tour of the PET-CT pathway observed by patients before their actual first PET-CT procedure, reduces their anxiety more than the control (reading a PET-CT leaflet).
Ethics approval(s)Approved 06/04/2022, London - Queen Square REC (HRA NRES Centre Bristol, 3rd floor, block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)2071048225, (0)2071048284; queensquare.rec@hra.nhs.uk), ref: 22/LO/0140
ConditionReduction of claustrophobia and procedural anxiety
InterventionParticipants are randomised into the Intervention group or Control Group.
Randomisation is completed using a web-based randomisation system using a simple computer-generated random number sequence list (sealedenvelope.com) for 20 patients, ensuring 10 participants in each group. Block randomisation will be used, and these blocks will consist of 4 participants. All participants are given a non-validated Anxiety Questionnaire after informed consent and eligibility. The Intervention group are given the virtual tour and their heart rate is measured during the intervention. 10 mins before their actual appointment time, the Anxiety questionnaire is completed again. Heart rate is monitored during the actual PET-CT scan. An interview is conducted after at least 1 day to gather information to improve the intervention. Control groups receive the anxiety questionnaire after consent and eligibility and are then asked to return to the waiting room with a PET-CT leaflet. 10 mins before their scan, they are asked to complete the anxiety questionnaire again. Heart rate is measured during the real PET-CT. No interview is required for the control group.
Intervention typeBehavioural
Primary outcome measure1. Anxiety measured using Anxiety Questionnaire scoring at baseline and after the intervention (10 mins before PET-CT appointment time)
2. Acceptability and experience of the intervention measured using interviews from Day 2 onwards
Secondary outcome measuresComparison of mean Heart Rate measurement measured using an optical sensor between virtual tour PET-CT bore experience and real PET-CT experience
