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)
Participants will be recruited by the PhD student and Research Fellow at kidney transplant outpatient clinics with the assistance of the renal transplant coordinators and nephrologists at the five sites. People who express interest in participating in the study will be visited in their homes for informed consent and enrolment by the Research Fellow. Each patient will be given a code number which will be given to the off-site statistician for treatment allocation
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Centralised, stratified randomisation of participants based upon the site (5 sites involved)
Off-site statistician prepares an excel file containing a sheet for each of the five sites containing the randomisation list and unique randomisation number and treatment allocation in sequential order
Masking / blinding

Statistical methods / analysis
Intention-to-treat. Descriptive statistics will be used to compare baseline characteristics. Categorical data will be presented as frequencies and percentages. Normally distributed data will be presented as means and standard deviations and non-symmetrical data as medians and inter-quartile ranges. The primary analysis will be based on the follow-up data by assessing the difference in adherence based on the MEMS score using a linear mixed-effects model. This model will accommodate for the unequal variances in repeated measurements while adjusting for random effects of participant. Secondary analyses, including medication adherence measured using surrogate and self-reported measures of medication adherence will be analysed using linear mixed-effects model for continuous variables and generalized estimated equation for binomial outcomes.

To estimate the sample size we wish to detect an increase of 7% in the MEMS score in the intervention group, allowing for a standard deviation of 9% in each group. Assuming a two-tailed hypothesis test with significance level of 5% and a power of 80%, we estimate at least 27 patients are required in each group. Taking into consideration an attrition rate of 20%, the number required is 32 per group, making a total sample of 64 participants. Our preliminary work with our partner investigators have suggested that attrition is likely to be higher based on their experience with this group of patients.
