Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In this two-arm, parallel-design, superiority, randomised controlled trial, participants randomised to the intervention group will receive access to a 4-module consumer-focused Massive Open Online Course (MOOC) about osteoarthritis (OA) and its management.

After randomisation, participants will receive an email from the research team, which contains details of how to access the course online. Participants will be asked to access the course at home, on their own device and complete module 1 within 7 days of enrolling in the course. Thereafter, they will be encouraged to complete 1 module per week and will be given 5 weeks to complete all 4 modules.

The consumer-focused MOOC contains educational information about OA and its management that aligns with best evidence/clinical guideline recommendations for hip/knee OA.

The course information is presented in four modules using written text, videos, infographics, downloadable resources (including physical activity/exercise logbook and action plan templates) and learning activities. The course does not prescribe specific exercise. In total, the time required to complete all four modules and learning activities is approximately four hours (one hour per module).

The course was designed for this study. To monitor adherence, participants will be asked to self-report, at the 5-week timepoint, which course modules they have completed.

Comparator / control treatment
Participants in the comparator group will receive access to a 3-page electronic pamphlet about OA and its management, currently available online from a reputable musculoskeletal consumer organisation, Musculoskeletal Australia. The pamphlet is anticipated to take 5-10 minutes to read in full.

After randomisation, participants will receive an email from the research team containing the pamphlet as a PDF attachment. Participants will be asked to read the pamphlet within the coming 5 weeks. At the 5-week timepoint, they will be asked to self-report if they read the pamphlet or not.

On completion of their involvement in the study (completed 13-week outcome measures), they will be provided with access to the experimental course (MOOC).

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)
The person who will determine if a potential participant is eligible for inclusion in the trial will be unaware, when this decision is made, to which group the participant will be allocated. The randomisation schedule will be concealed in a password protected computer database. A member of our research team will maintain and access the schedule and reveal allocation to the Trial Coordinator as each participant requires randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be prepared by an independent biostatistician. Randomisation of eligible participants to the control group or the experimental group will be conducted using randomly permuted blocks of varying sizes in a 1:1 ratio, stratified by eligible joint (hip/knee).

Sample size:
A sample size of 60 participants per arm (120 in total) is required for 90% power to demonstrate that the consumer-focused MOOC is superior to the control with a two-sided 2.5% significance level (accounting for Bonferroni correction for multiple comparisons, across the two primary outcomes) and accounting for a 20% dropout rate. This sample size is based on the following assumptions: a standardised between-group effect size of 0.625 for self-efficacy for pain (based on our prior educational research, corresponding to an absolute between-group difference in mean change from baseline to 5 weeks in ASES pain subscale score of 1 unit favouring the MOOC, within-group standard deviation (SD) of 1.6 units correlation between measures across all three timepoints of 0.5 (i.e., compound symmetry variance-covariance matrix) and using a constrained longitudinal data analysis (cLDA) model. With this sample size, we also have at least 90% power to detect a between-group effect size of 0.8 for OA knowledge (conservative for this type of program), corresponding to an absolute between-group difference in mean change from baseline to 5 weeks in KOAKS/HOAKS score of 4.6 units favouring the MOOC, within-group SD of 5.8 units, and correlation between measures across all three timepoints of 0.2.

Statistical Analysis Plan: A statistical analysis plan will be written by the biostatistician and published on our research centre’s website while blind to group allocation. The analysis will include participants according to their randomised allocation (intention-to-treat). Demographic and baseline characteristics of participants will be summarised as appropriate and will be inspected to assess baseline comparability of treatment groups. Each continuous outcome including the two primary outcomes measured at baseline and two follow-up timepoints will be analysed using a cLDA model. For continuous outcomes with one follow-up timepoint, differences in change will be compared between groups using linear regression models adjusted for baseline levels of these outcomes, where available. For binary outcomes, differences between groups will be compared using risk differences and risk ratios, obtained using log-binomial regression models, adjusted for the outcome at baseline where available. The proposed cLDA model provides valid inference in the presence of missing data if the data are missing at random. Should the amount of missing data for either primary outcome be greater than 5%, an analysis will be conducted using the delta-adjustment method under the pattern-mixture modelling framework in the context of multiple imputation to assess sensitivity to missingness not at random. All analysis models will be adjusted for the stratification factor, eligible joint (hip/knee).
