Phosphate Kinetic Modeling 2

The study aims to investigate the concept of computer based Phosphate Kinetic Modeling (PKM) in the hemodialysis patient population. This computerized algorithm model was developed as a tool to aid physicians in controlling a hemodialysis patient's phosphate level. Once a subject consents to participate in the study, the subject's dietary phosphate intake will be estimated by the modeling program and the appropriate dose of the phosphate binder calcium acetate (PhosLo) will be recommended accordingly. If necessary, the Ca++ concentration of the dialysate will be changed to remove any excess calcium absorbed as the result of an increase in the PhosLo prescription to control phosphorus.
