Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Design: This is a multi-centre pragmatic randomized controlled trial with 0, 3, 6 and 12 month data collection points; both quantitative and qualitative methods will be used.

Population: The study population consists of adults with Stage 5 chronic kidney disease who are currently receiving in-centre or home-based haemodialysis or peritoneal dialysis.

Intervention: Participants who are randomized to the intervention will be invited to use the SUCCESS app for a maximum of 12 months. The SUCCESS app was designed to include informational content, covering diet, fluids, medicine, physical activity, emotional wellbeing and supportive care. Furthermore, the SUCCESS app includes features to improve the communicative and critical health literacy skills of patients across four domains: skills to a) access, b) understand, c) appraise and d) use/act on health information to make health decisions and be involved in self-management. Participants will be instructed to engage with the SUCCESS app as often as they would like. App analytics will be used the monitor the usage patterns of the app.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants dialysis at home will be randomised centrally using simple randomisation. t is not feasible to randomise patients individually when attending in-centre dialysis given likely intervention contamination (where the intervention is experienced by controls as well as those allocated the intervention) when control and intervention participants dialyse in the same room three times each week for several hours. However, in-centre patients always attend on the same days; patients either dialyse on Monday, Wednesday and Friday (MWF) or Tuesday, Thursday and Saturday (TTS). We will therefore use a pragmatic approach by randomising the pattern of attendance, not the patient; by centre, all participants attending MWF would be randomly assigned to the SUCCESS intervention, or not.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An interactive Voice Response System will be used for randomization.. Participants will be randomized using minimization and 2 stratification factors, including: language spoken at home and research site.

Efficacy
Statistical methods / analysis
All analyses will be by intention-to-treat comparing the intervention and usual-care arms. For continuous and binary outcomes, linear and logistic regression models will be used respectively, with the study arm as a covariate. All models will also be adjusted for centre using a random effect and both type of patient (home-based or in-centre), and dialysis-schedule will be adjusted for using fixed effects.

Summary
Brief summary
We have developed a smartphone App to support participation in decision-making for adults with stage 5 chronic kidney disease who are currently receiving haemodialysis. The App is called the SUCCESS App. It includes information about:
• Diet
• Fluids
• Physical activity
• Medicines
• Emotional wellbeing
• Supportive care
• Health literacy skills
The purpose of this study is to investigate whether the SUCCESS App supports adults with chronic kidney disease to make decisions about their health, and helps increase knowledge, skills and quality of life.
