Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A 30-minute musculoskeletal ultrasound (MSK US) of clinically involved joint(s) by a rheumatologist trained in this imaging modality. During the session, participants will be shown real-time images of one or more inflamed joints. The operator will explain the anatomic landmarks (eg tendon, joint space, cartilage) and sonographic findings (eg, synovitis, erosion, effusion, doppler flow). Images will be compared to still sonographic pictures of a normal joint. The examination will take approximately 30 minutes on one occasion and will occur in a quiet darkened room.

Behaviour
Comparator / control treatment
Standard care involving a 30-minute education session with a rheumatology healthcare professional (explanation of rheumatoid/psoriatic arthritis and the medication mechanism of action and risks and benefits ) and provision of a Medication Information Sheet containing information regarding the relevant DMARD from the Australian Rheumatology Association website (www.rheumatology.org.au),

Outcomes
Primary outcome [1] 327096 0
The Compliance Questionnaire-Rheumatology (CQR) will be used to assess patient medication adherence. The CQR is a 19-item Rheumatology-specific self-administered instrument with predictive validity when tested against objective measures such as Electronic Medication Event Monitoring. The total score calculated ranges from 0 (non-compliance) to 100 (maximum compliance) with a cut-off of >80 used to define satisfactory medication adherence. This tool has been well-validated in patients with IA.

Secondary outcome [1] 393770 0
1) Medication Adherence Rating Scale (MARS)
This self-report instrument consists of six questions relating to non-adherent behavior and has good validity and reliability in patients with a range of diseases, including IA and psoriasis. Responses to six items assess the frequency of unintentional (e.g. ‘I forgot’) and intentional (e.g. ‘I decided to miss a dose’) non-adherent behaviour are recorded using a 5-point Likert scale. The total score ranges from 6 to 30 with higher scores indicating higher self-reported adherence. Patients can be categorized into “high” or “low” adherers (MARS greater than or equal to 26 or lesser than or equal to 25). This outcome measure will be used with the CQR to determine if findings from the shorter MARS questionnaire correlate with those from the longer CQR. If so, the MARS may be a more convenient outcome measure in intervention studies assessing medication adherence.

2) Patient willingness to escalate immunosuppression. This will be assessed using an anchored visual analogue scale (VAS; range 0-100), where 0 equals to not willing under any circumstances and 100 equals to definitely willing.

5) Beliefs about Medicine Questionnaire (BMQ). This instrument contains 11 questions assessing cognitive representation about medication, in particular patient beliefs about the necessity of prescribed medication and their concerns regarding medication toxicity.

6) EQ-5D-5L (www.euroqol.org). This is a comprehensive health-related QOL assessment tool used for over 30 years. Patients are asked to self-score their health in five domains (mobility, self care, usual activity, pain/discomfort and anxiety/depression). Data obtained allows calculation of Quality Adjusted Life Years.

Attendance at the trial site (Westmead Hospital) will be minimised by provision of blank questionnaires to be completed and returned in a stamped addressed envelope at specific times post-intervention: Week 4 (Timepoint 1), Week 12 (Timepoint 2) and Week 24 (Timepoint 3). Text reminders will be sent by investigators to study participants to prompt questionnaire completion at the appropriate time-points.

7) Patient experience of MSK US and patient education session. Participants in both groups will be given a blank white post-card at the end of the MSK US and patient education session to record their experience of the session in free text. Patients will be asked to place these in a sealed study box which will be opened at study conclusion for data analysis.

Efficacy
Statistical methods / analysis
Using a two-tailed test with a significance level of 0.05, a sample size of 34 patients per group provides 90% power to detect a difference of 10 points on the CQR with a standard deviation (SD) of 12.54. Allowing for a 20% dropout rate, we aim to recruit 40 patients per group.

Data from postcards "patient experience of musculoskeletal ultrasound and patient education session" will be collated and managed using QSR NVivo 8 and thematically analysed using the Framework Method. A list of overall and individual themes will be compiled to allow for comparison between those randomised to standard care or intervention. Qualitative findings will be interpreted against other quantitative study data to provide further insight into patient perspectives and integration of both types of data to inform overall study findings.

Recruitment should be able to be performed over 24 months. Variables will be normally distributed, so an analysis of variance (ANOVA) will be used to compare the mean±SD of study parameters. P<0.05 will be considered statistically significant. Pearson correlation coefficients will be used to assess the relationship between patient beliefs and medication adherence. Any missing data will be imputed using the estimated regression mean method in StataTM.

Summary
Brief summary
Medications to treat rheumatoid arthritis and psoriatic arthritis have possible side effects. People may be unwilling to take them if they are unaware of the benefits. Educational tools using pictures may improve people’s understanding of arthritis and medications.

Musculoskeletal ultrasound (US) is useful in assessment of joint inflammation and damage. It is portable, non-invasive, and allows joint structures to be seen in "real-time". It may be rapidly done by a trained user. There is strong evidence that US is of value in monitoring the severity of rheumatoid arthritis and psoriatic arthritis. Recent work by our research group has shown that patients found real-time US more useful than written leaflets or online information for understanding rheumatoid arthritis and medications used to treat it.

The aim of this study is to determine if showing people with rheumatoid or psoriatic arthritis “real-time” US of their inflamed joints:

i) improves their willingness to take an extra medication which turns off inflammation (Disease Modifying Anti-Rheumatic Drug, or DMARD) and
ii) increases their willingness to keep taking this medication (medication adherence)
