Objectives

The safety and efficacy of sevelamer hydrochloride in binding phosphate in patients with end-stage renal disease and its ability to attenuate the progression of cardiac calcification have been well documented but not the longer-term health and economic implications. Thus, a model of the predicted long-term consequences of sevelamer compared with calcium-based binders (acetate and carbonate) was developed.

Methods

Long-term cardiovascular implications of 1 year of treatment with phosphate binders in patients on hemodialysis are estimated based on the patient's demographics, comorbidities, and physiologic and renal parameters. The initial calcification score and expected changes over 1 year are derived using regression equations developed from the Treat-to-Goal study and translated to cardiovascular disease risk based on equations developed from a long-term cohort study. In this article, the implications of cardiovascular disease for life expectancy and medical costs are accounted for from a US payer perspective.

Results

The cardioprotective effect of sevelamer over 1 year is estimated to result in a 12% reduction in cardiovascular events compared with calcium acetate. In a population of 100 patients, the savings of $205,600 accrued due to avoiding nine cardiovascular events with sevelamer, largely offset the increased binder costs, leading to a favorable cost-effectiveness ratio of about $2200 per (discounted) life-year gained.

Conclusions

Although both binders provide equivalent phosphate binding capacity, the results indicate that the advantage of 1 year of treatment with sevelamer in attenuating the progression of calcification has important clinical and economic consequences, suggesting that this provides good value for money.
