Home hemodialysis, particularly when delivered more frequently, is shown to significantly improve patients' quality-of-life and other important clinical outcomes. Because traditional in-center dialysis treatment schedules are constrained by staffing and time-slot availability, home therapy presents additional flexibility with which to address clinical and lifestyle needs. This readily accessible tool will help clinicians decide upon the course of care to achieve their objectives.

Using formulas from peer-reviewed publications, the Dosing Calculator quickly displays a wide range of therapy frequencies and durations to assist nephrologists in prescribing for a desired dose. This online tool is expected to significantly reduce nephrologist time in calculating and assessing hundreds of possible prescription options to achieve clinical goals.

"We are committed to increasing access to home hemodialysis therapy based upon its life-changing benefits to patients and their families, and ensuring a simple prescription process is important to this goal," said Jeffrey H. Burbank, Chief Executive Officer of NxStage Medical, Inc. "With this web-based tool, physicians now have a new way to target their clinical goals while giving patients maximum flexibility to live their lives as they wish."

The interactive online tool is available on the NxStage web site or can be accessed directly at http://dosingcalculator.nxstage.com. The Dosing Calculator is a free service for health care providers.

About the NxStage System One

The NxStage System One is the first and only truly portable hemodialysis system cleared for home use by the U.S. Food & Drug Administration (FDA). Its simplicity and revolutionary size (just over a foot tall) are intended to allow convenient use in patients' homes and give patients the freedom to travel with their therapy. When combined with the NxStage Pureflow SL Dialysis Preparation System, patients are able to further simplify, using ordinary tap water to create dialysis fluid on demand. Unlike conventional hemodialysis systems, the System One requires no special infrastructure to operate. Under the guidance of their physician, patients can use the NxStage System One, with their trained partners, where, how and when it best meets their needs, at home or on vacation. http://www.nxstage.com/.
