Description of intervention(s) / exposure
Electroacupuncture for recovery of erectile function after robotic assisted radical prostatectomy: A feasibility study and randomised controlled trial.
Standardised Protocol
INTERVENTION GROUP A
Participants in Group A (intervention) will be required to attend 10 visits over 8 weeks. 2 visits in the first 2 weeks and then 1 visit each week until the 8 weeks is complete. Scores are filled out week 1, 5 and the final scores are filled out in week 9. The credibility and acceptability questionnaire consist of 2 questions prior to treatment and 2 questions on completion of treatment. The first visit is the enrolment visit and treatment session will take 60 minutes. Each subsequent treatment visit will take 40 minutes. Group B (usual care) will fill out the scores remotely at week 1, 5 and 9. The scores for both groups will take approximately 10 minutes.
A standardised protocol will be administered. Participants will receive 15 acupuncture points at each session. The selection of these points is based on traditional acupuncture point function as per Deadman (Deadman, Al-Khafaji, & Baker, 1998) and anatomically local points.
The intervention session will take 40 minutes. The patient will be positioned prone on the treatment table and asked to disrobe down to underwear and they will be covered with a towel. After a brief explanation of the intervention, the acupuncturist delivering the intervention will insert the acupuncture needles.
The person delivering the intervention is a registered acupuncturist with over 15 years clinical
experience.
The needles will be retained in situ for a minimum of 20 minutes.

Single use disposable stainless steel needles with gauge 0.20 x 25 mm and 0.22 x 40 mm. Needle size has been chosen due to suitability to the anatomy of the acupuncture point.
Each session will be 40 minutes, and the needles in situ for 20 mins.
The intervention can be administered >6 weeks and <24 months after robotic assisted radical prostatectomy.
Participants attendance and compliance will be recorded under the primary feasibility objective of retention and intervention adherence. Attendance and compliance is recorded on the assessment log

Group B - The usual care group is the control group. Group B is defined continuing with their 'usual care' medication and/or use of erection rehabilitation devices but group B does not not receive the intervention.
Participants in Group B will be required to complete the same questionnaires via a secure online email link. Group B will be offered the intervention treatment at completion of the trial if it is shown to have some benefit.

Outcomes
Primary outcome [1] 326440 0
To investigate feasibility and acceptability we will record and assess the following key trial parameters of screening, eligibility, consent, recruitment rate, intervention adherence and adverse events independently. Screening: The screening rate is defined as the number of males who had undergone a radical prostatectomy with unilateral or bilateral nerve spare and were deemed acceptable to the trial after meeting the inclusion/exclusion criteria. Acceptance or decline rates will be noted. This data is collected from the study from the screening log and enrolment.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised into 2 groups: one being the intervention and the other being usual care. The sequence generation of participants to either the intervention or control (usual care) will be undertaken using a computer random number generator (Research Randomizer: https://www.randomizer.org/).

Statistical methods / analysis
Sample sizes will consist of 2 groups of 30 men per arm of the trial which is sufficient to determine numbers for a larger trial (Billingham et al., 2013); this requires a recruitments number of 72, for a dropout rate of 20%.

Key trial parameters of screening, eligibility, consent, recruitment rate, intervention adherence and adverse events will be presented as descriptive statistics. We used ANOVA to identify between-group differences, adjusting for baseline score as a co-variate. Where data was not normally distributed, we used non-parametric measures (Mann-Whitney U tests). Intention-to-treat analysis was used. Analysis and interpretation of the findings was conducted by blinded investigators. Investigators agreed on the interpretation of the findings before revealing the allocation of either group. At the time of interpretation of findings, the two groups were only referred to as “Group 1” or “Group 2”. Group numbers were also not revealed as this could have compromised blinding.

Thematic analysis will be used for the data in the open ended comments box (Braun & Clarke, 2006).
Secondary objectives: Changes in erectile function as measured by the IIEF-5/SHIM, EHS and EPIC.

Summary
Brief summary
This study will investigate the feasibility, acceptability and effect of electroacupuncture on erectile dysfunction after robotic assisted radical prostatectomy in prostate cancer patients

Who is it for?
You may be eligible to join this study if you are over 18 and have undergone robotic assisted radical prostatectomy > 6 weeks ago and <=24 months ago and experience erectile dysfunction as a result of the surgery.

Study details
Participants in this study are randomly allocated (by chance) to one of two groups. Participants group A will receive an electroacupuncture intervention for 10 visits over 8 weeks. Participants group B will continue with their usual care which may include medications and use of devices.

Feasibility and acceptability of the intervention will be assessed by recording key trial parameters of screening, eligibility, consent, recruitment rate, intervention adherence and adverse events. Erectile function will be assessed using questionnaires.

It is hoped that this research project will provide more information on whether electroacupuncture could be another treatment option for erectile dysfunction after radical prostatectomy which would improve the lives of many men.
