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.
