Study hypothesis
Initially, a small pilot study of qualitative design will be carried out. The aim of this first part of the study will be to explore renal patients' concept of the mechanisms by which phosphate binding medication works and how this type of medication should be used. During the second stage, an intervention targeting patients' non-adherence with phosphate binding medication undergoing renal replacement therapy will be implemented. The intervention will be psycho educational and have as an aim to assist patients to change treatment related beliefs important in shaping medication adherence behaviour.

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.
