Background to Research Main research question: ‘What are the barriers preventing some patients from achieving adequate phosphate control’ Main research question: ‘What are the barriers preventing some patients from achieving adequate phosphate control’ Aims of the study: To explore patient perspectives of what prevents them from achieving adequate phosphate control. Aims of the study: To explore patient perspectives of what prevents them from achieving adequate phosphate control. To develop strategies that can be adopted by the health care professionals to support patients in controlling their serum phosphate. To develop strategies that can be adopted by the health care professionals to support patients in controlling their serum phosphate.

Patients with end stage renal failure (ESRF) requiring renal replacement therapy either haemodialysis or peritoneal dialysis Compliance with treatment regimes is a continuing challenge for patients Control of serum phosphate is an important component of this treatment High phosphate causes metastatic calcification in joints and myocardium and triggers hyperparathyroidism

Removal of phosphate by dialysis is relatively inefficient Requires the patient to restrict their phosphorous intake (milk, dairy products, offal, cola, chocolate) and take phosphate binding medication Past research has shown that dialysis patients are prone to none compliance Reported rates range from 25% to 83%

The most frequently used method to promote compliance is the provision of information Studies have shown that educational interventions can have some impact on patients knowledge of phosphate control and their compliance Growing body of research that indicates that medical compliance involves more than educating patients A previous study undertaken within renal unit highlighted this

Research Design : Qualitative semi-structured interviews Setting : Haemodialysis (HD) and peritoneal (PD) patients at BFTHT Sample: patients receiving regular dialysis with serum phosphate levels of > 1.8mmols/l for 3 consecutive months Measures: A semi structured interview schedule has been devised to identify the patients perceptions of issues that impact on control of phosphate

Inclusion Criteria: patients undergoing HD or PD for > 6 months with a serum phosphate level of > 1.8 for 3 consecutive months Who have had an intervention from a dietician for specialist advice about control of phosphate Recruitment: Consent Process:

Interview Process: Questions 1)Can you tell me about how meal times are organised in your family/home 2)If there is an event or circumstance that is a change from your normal routine can you discuss how you would make decisions for food choices 3)Can you tell me something about how you organise taking your medications 4)Can you tell me something about your experience of how hcp’s deal with issues around your phosphate levels

Ethical Approval: Will be sought from the local LREC Data Analysis: Content analysis will be used to identify themes and categories from the qualitative data. Results:
