Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In an outpatient clinic the patient presenting for a TRUS biopsy will wear a Virtual Reality (VR) headset and watch a movie for the duration of the biopsy preocedure, duration estimated at 10-15minutes. The software for the movie will be a distraction application used on other similar studies. It will not require movement or active particpation in the VR environment, but merely passively watching the VR movie. The procedure will be carried out by a urology consultant or registrar with a urology nurse assisting. The biopsy procedure itself will not alter, it will be a standard ultrasound guided transrectal biopsy of the prostate and use local anesthetic.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
randomisation completed by biostatistician, allocation in opaque sealed envelopes, operator will only find out once the nurse has opened the assigned envelope after consent obtained
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis

A sample of 200 (100 per group) is required to ensure that there is at least 80% power to detect a difference of 1 on the primary outcome pain scale assuming a standard deviation of 2.5 and a 5% significance level. We will recruit 250 people (125 per group) to allow for a 20% drop out rate. This sample size also ensures that there is at least 80% power to detect a 0.4 standard deviation difference in the secondary outcome of anxiety using a 5% significance level.

A regression model (equivalent to an independent samples t-test) will be used to compare the mean level of pain between the intervention and control groups . Potential confounders will be added to this regression model to adjust for any imbalance between the arms. These may include age, chronic pain conditions ……. A similar approach will be undertaken to analyse the secondary outcome of anxiety.
