  1. Research question Can a web-based nutritional educational intervention improve phosphorus knowledge and control of phosphorus intake?
  2. Experimental design

    Following enrollment and informed consent, subjects will be randomized to one of two arms (group1: usual care; group 2: usual care plus Internet-based nutrition module). All subjects will undergo baseline data collection, consisting of:

    1. Short form of the test of functional health literacy in adults: categorizes individuals as having adequate, marginal or inadequate health literacy.
    2. Chronic Kidney Disease (CKD) Knowledge Assessment Tool: addresses nutritional knowledge of CKD.
    3. SF-12 Health Survey version 2: a 12-item measure of health related quality of life.
    4. Kidney Disease Self-Management Survey: a 58-item Likert scale based on theories important for self-management in chronic disease.
    5. 3-Day Dietary Diaries
    6. Lab work:

    i. Serum phosphorus, calcium and parathyroid hormone levels. ii. Circulating endothelial cells, a novel marker for vascular damage.

    Following baseline data collection, group 1 will continue with their scheduled clinic visit, while group 2 will spend approximately 30 minutes completing a web-based nutrition module. After completion of the module, patients will proceed with their scheduled clinic visit.

    All subjects will then be asked to return in 30-60 days to repeat some of the survey information and blood work

  3. Major risks to subjects There is the potential for some mild discomfort from the necessary blood draws, which occur twice per subjects.
  4. Potential benefits to subjects Subjects randomized to the web-based module may receive an educational benefit from it.
  5. Consent procedures Only individuals who can provide their own consent can participate. Upon agreeing to enroll, a study coordinator or investigator will provide the subject with a copy of the consent form, and will remain available to answer any questions.

Primary Outcome Measures:
  • After one month gains in phosphorus knowledge will be assessed by the CKDKAT. [ Time Frame: 4 to 8 weeks post intial questionnaire/survey and placement in one of two groups ]
  • After one month compliance with dietary phosphorus intake will be measured by mineral metabolism laboratory values (serum phosphorus, calcium, PTH, calcium phosphorus product). [ Time Frame: 4 to 8 weeks after initial questionnaire/survey appointment ]
  • After one month compliance with dietary phosphorus intake will be measured by the 24 hour recall diary. [ Time Frame: 4 to 8 weeks after initial questionaire/survey appointment ]
  • After all groups have completed their visits, statistical comparisons will be made to determine whether eHealth information was able to improve patient knowledge of and compliance with recommended dietary phosphorous intake. [ Time Frame: two years for all subjects to be enrolled and data to be analyzed ]

Secondary Outcome Measures:
  • After all groups have completed their visits, correlations between dietary phosporus intake, serum phosphorous levels and CECs will be made. [ Time Frame: two years for all subjects to be enrolled, data to be analyzed ]
