NCT01643486

Brief Summary

Hypothesis: The use of a program that assists with selection of the appropriate number of phosphate binders for a meal based on patient specific factors will result in improved serum phosphate control, a reduction in overall number of phosphate binders used and enhanced patient satisfaction. Primary Aim: To determine if teaching patients to use a 'phosphate counting' program installed on an iTouch that selects the appropriate amount of phosphate binder to be taken with each meal is associated with better phosphate control than usual care. Research Plan: There will be 3 phases to the study. Phase 1: Recruitment of 60 peritoneal dialysis (PD) patients. The information generated from this phase will be used to develop the iTouch program for phosphate counting and matching binder number. Phase 2: iTouch program once developed will be pilot tested on a convenience sample of 10 PD patients and modified if required. Phase 3: Randomized controlled trial of 92 PD patients to determine if using the iTouch phosphate counting program reduces serum phosphate compared to controls. Success would be based on seeing a statistically significant difference in serum phosphate as expected from our sample size calculation

Outcome Measures

Primary Outcomes (1)

  • Serum Phosphate

    The primary end point of the study will be a comparison of the serum phosphate between the two study groups at the end of the 3 months. An unpaired t-test will be used with a value of \<0.05 considered to be statistically significant in an intent to treat analysis.

    3 months

Study Arms (2)

iTouch phosphate counting program

EXPERIMENTAL

All patients will have an iTouch that will help them to calculate the required number of phosphate binders to be taken with each meal

Other: iTouch phosphate counting program

Usual Care

ACTIVE COMPARATOR

Participants in the active comparator group will document their meals in the iTouch but continue to take their phosphate binders as prescribed by their MD/dietician

Other: Usual Care

Interventions

After developing and pilot testing the iTouch phosphate counting program, the participants in the intervention arm will enter their meal into the program; the required number of phosphate binders will be calculated for the patient

iTouch phosphate counting program

The patients randomized to the usual care arm will continue to receive the usual dietary counselling and will input meal data into the iTouch program but no recommendations for the number of phosphate binders to be taken with the meal will be provided

Usual Care
