Plain English summary of protocol

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. Most patients will have some form of anxiety when having their first PET-CT scan and so an intervention that would help alleviate procedural anxiety and improve the patient experience is welcomed. 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 procedure-related anxiety and improve the patient experience. The Virtual Tour (VT) is very much like the VTs 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 VT tour for any patient having their first PET-CT and collect data on anxiety before and after the VT. This pilot will inform and appropriately power a larger trial (multi-centre) 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 a non-validated anxiety measure before and once again after the intervention. The second measure will be taken before the patient's actual PET/CT scan. Heart rate will also be measured during the VT and during the actual PET-CT scan. These will be compared to see if the mean heart rate is reduced when compared to the VT mean heart rate. An interview is conducted a day or two after the PET-CT scan to gather information on the participant's experience, which will be used to further improve the VT.

What are the possible benefits and risks of participating?
The researchers are conducting this trial to see if our current prototype is acceptable and if there is a potential benefit in reducing anxiety directly regarding the scan. They do not know if the VT will reduce a patient’s anxiety, which is why they are doing this study. It is hoped that the information from this study will help 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 VT is also a possibility, however, the tour has been designed to mitigate this risk and include mostly static viewpoints.

Scientific titleFeasibility study on the acceptability of a virtual reality tour for patients referred for their first PET-CT scan
Study acronymPET-CT VR Tour HR
Study objectivesThat the current prototype virtual tour is acceptable to patients. A virtual tour of the PET-CT pathway observed by patients before their actual first PET-CT, reduces their heart rate during the real PET-CT compared with their heart rate during the virtual tour PET-CT.
Ethics approval(s)

Approved 27/02/2023, London - Dulwich REC (HRA, Skipton House, 80 London Road, London, SE1 6LH, United Kingdom; +44 (0)2071048094; dulwich.rec@hra.nhs.uk), ref: 23/LO/0050

Health condition(s) or problem(s) studiedReduction of procedural anxiety
InterventionAll participants have the Virtual Tour (VT). All participants are given a non-validated Anxiety Questionnaire after informed consent and eligibility. During the VT their heart rate is measured. 10 minutes before their actual appointment time, the Anxiety questionnaire is completed again. Heart rate is monitored also during the actual PET-CT scan. An interview is conducted after at least 1 day to gather information to improve the intervention.
Intervention typeBehavioural
Primary outcome measure(s)

1. Heart rate measured using an optical sensor during virtual tour PET-CT bore experience and real PET-CT experience
2. Acceptability and experience of the intervention measured using interviews from Day 2 onwards

Key secondary outcome measure(s)

1. Anxiety measured using Anxiety Questionnaire scoring at baseline and after the intervention (10 min before PET-CT appointment time)

Completion date30/06/2023
