Brief summary

This study aims to test the effectiveness of an innovative educational intervention ‘4D’. The intervention integrates all four methods of phosphate control, incorporating teach-back as a teaching strategy to improve adherence behaviours to phosphate control in adults receiving haemodialysis, with a target to maintain a serum phosphate level at near normal level between 0.7 – 1.6mmol/L. The anticipated study out comes will be reduced serum phosphate levels, increased knowledge on phosphate control methods, increased adherence to diet, phosphate binder medication and haemodialysis and increased self-efficacy for managing chronic disease

Interventions

The intervention was guided by the behavioural theory Social Cognitive Theory. It consists of six (30-45 minutes) individual face to face educational sessions with the aid of a PowerPoint presentation via a laptop, teach-back and a booklet. Four initial educational sessions are in weeks one, two, three, four; and two booster sessions in weeks eight and 12. Both the educational topics and the booklet was developed following a systematic review and in consultation with an expect peer panel review

Four initial educational sessions are in weeks one, two, three, four; and two booster sessions in weeks eight and 12. Both the educational topics and the booklet was developed following a systematic review and in consultation with an expect peer panel review. The educational topics and the booklet covers information on i) dietary phosphate control, ii) phosphate binder medications to reduce intestinal phosphate absorption, and iii) haemodialysis prescription to promote removal of phosphate. The teach-back method is used as a teaching method to ensure understanding of information provided during the educational session. Participants will also be encouraged to use the booklet during teach-back and at home to guide their self-management goals. An experience haemodialysis nurse will deliver the intervention to participants during their haemodialysis treatment times.
