Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
After undergoing Carpal Tunnel release surgery all patients at the participating hospital currently receive a written leaflet developed by the hand therapy team. This is given to the patient at their first post-operative appointment with the nurse and surgeon, 10-14 days post-surgery. The leaflet describes the surgical procedure in plain language and includes a diagram of the anatomical structures. It provides information regarding wound care, timing of stitch removal, management of swelling, recommended hand exercises, and activity precautions.

Those randomised to the intervention group will also receive one face-to-face 30 minute hand therapy appointment on the same day (i.e. after their first post-operative appointment with the nurse and surgeon). In this appointment, the occupational therapy student researcher (under supervision of a senior hand therapist) will reiterate the information in the leaflet, ask about symptoms, check the recovery of the wound, demonstrate exercises and scar management and answer questions.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer - this will be created by an independent blinded researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use block randomisation (in groups of eight) to allocate participants to one of two groups. Allocation will be determined using a computer generated random number sequence.
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Preliminary data for participant outcome measures collected pre-operatively and then at three post-operative appointment time points will be compared between groups using t tests for normally distributed data and Wilcoxon rank-sum tests for skewed data.

A cost-benefit comparison will include utility scores calculated from EQ-5D-5L and we will also compare health resource utilisation and days off work.

For all analyses, a two-sided p value < 0.05 was considered significant.

Data will be analysed by the student researcher (under supervision of supervisors blinded to group allocation) using Statistical package for the Social Sciences (SPSS) v 25.

Summary
Brief summary
After undergoing Carpal Tunnel release surgery, Peninsula Health patients currently are provided with a written leaflet developed by the hand therapy team at their first post-operative appointment. This is usually 10-14 days post-surgery. It is possible that patients may recover faster if they also receive a face-to-face consultation with a hand therapist, however there is only low level evidence from a retrospective case series study (Mack et al., 2017) to support this.

We propose to complete a pilot study to see whether a randomised control trial would be feasible at Peninsula Health. The pilot study will take place over a 6 month data collection period, which is predicated on research honours student availability. Based on 2017 data, it is anticipated that the study could recruit a minimum of 50 patients.

In this pilot study, participants will be randomised to two groups:

1: control group who will receive usual treatment (written information provision)
2: treatment group who will receive usual treatment plus one face-to-face hand therapy appointment

We aim to collect data pre-operatively and then on three occasions over a 12 week timeframe: initial post-operative phase (10-14 days after surgery), 6 weeks and 12 weeks. Patient-rated outcome measures will include the Boston Carpal Tunnel Questionnaire; Quality of Life (using the EQ-5D-5L) and patient satisfaction with their recovery. We will also report on any complications such as Pillar Pain, infection and wound breakdown. Participants will be offered the choice of paper, on-line or phone-based completion of these measures.

We will also conduct a basic cost-benefit analysis using utility scores calculated from the EQ-5D-5L and information regarding time off work and other health resource usage.
