Patients' experiences and perspectives of a mobile phone text messaging intervention to improve dietary behaviours in haemodialysis.

Aim: Dietary requirements for people on haemodialysis are complex and often poorly adhered to. Mobile phone text messaging offers a simple strategy to enhance current nutritional care. KIDNEYTEXT was a 6-month pilot randomised controlled trial that evaluated the feasibility and impact of mobile phone text messages to alter participants' dietary behaviours. The aim of this study was to elicit the perspectives of people on haemodialysis regarding acceptability of mobile phone text messages targeting dietary behaviours.
Methods: Semi-structured interviews were conducted with participants in the intervention arm of the KIDNEYTEXT study. Participants were purposively sampled and interviews were conducted in-person or over the phone. Transcripts were thematically analysed using principles of grounded theory.
Results: Interviews were conducted with 25 participants. Four major themes were identified: building awareness (reinforcement of information, simple and comprehensible, guiding choices, accessible information enhancing motivation, gaining skills in management), valuing care (boosting self-esteem, in-person care bolstered by reminders), activating change (adjusting lifestyle, gaining control of electrolytes and fluid, striving to improve overall health), waning attention and motivation (lack of personalisation limiting change, maintaining the status quo, reverting back to old habits).
Conclusions: Participants perceived that the KIDNEYTEXT intervention enabled participants to build on their knowledge through the dissemination of simple and actionable content. Participants appreciated frequent reminders of how to improve their diet and felt that this increased contact motivated them to alter some dietary behaviours. Future trials should consider strategies to enhance personalisation to further motivate dietary change.
