Exploring end stage renal disease patients' beliefs about phosphate binding medication and intervening to improve their adherence.

INTERVENTION: An interview schedule will provide the framework for the semi‐structured interviews conducted for the purpose of the first part of the study. The intervention will involve a demonstration of mixing a solution of phosphate binding medication in a phosphate solution with an accompanying explanation of how this treatment is beneficial to renal patients. A randomised controlled trial design will be followed with patients being allocated to receive either the intervention or treatment as usual. Phosphate levels will be obtained via the patients' notes, together with other outcome measures. These will be analysed and compared with the baseline measures previously recorded so that the effectiveness of the intervention in terms of improving adherence can be evaluated. CONDITION: Urological and Genital Diseases: Renal disease ; Urological and Genital Diseases ; Chronic renal failure PRIMARY OUTCOME: Laboratory blood measurements obtained from patient notes at baseline and at 3‐month follow up will serve as outcome measures together with measures such as patients' satisfaction with information regarding this treatment and understanding of the nature of treatment. SECONDARY OUTCOME: Not provided at time of registration INCLUSION CRITERIA: Approx. 90 (10 for the qualitative study and 80 for the intervention) patients will be recruited from the Renal Unit at Guy's Hospital. Patients asked to participate will be kidney failure patients on renal replacement therapy (haemodialysis). For patients to be included in the study, they have to be undergoing dialysis for at least six months and be on phosphate binding medication.
