Abstract
Aim: To investigate the effect of a structured, 12-week education programme on serum phosphate levels and knowledge
regarding phosphate management in haemodialysis (HD) patients.
Methods: Adult patients receiving HD at one tertiary institution were recruited to participate in a 12-Week Phosphate
Challenge. Dialysis nurses provided education regarding phosphate binders and diet, with patient participation tracked via a
points system. Serum phosphate, calciurn, chloride and bicarbonate were analysed at baseline and monthly thereafter for three
months. A post-programme questionnaire assessed patient satisfaction with the programme and the level of patients' knowledge
regarding phosphate management.
Results: Thirty-nine patients participated in the study. Dialysis vintage was between one and five years in the majority (69%)
of patients. Mean serum bicarbonate was the only variable to demonstrate a hnear dechne throughout the study. Mean serum
phosphate, calcium and chloride levels iremained stable. At the end of the programme, 60% of patients reported that they were
compliant with their phosphate binder medication and 56% felt confident with regard to managing their phosphate levels on a
daily basis. • • '
Conclusion: The 12-week Phosphate Challenge did not translate into lower serum phosphate levels. At the end of the
programme, patients reported high levels of compliance with phosphate medications and confidence with regard to managing
daily phosphate levels.
