The Second Annual NxStageUsers Group Meet-Up and Conference is being held from October 2nd to 5th in New Orleans. The event, Patient-Centered Dialysis: You’re in the Drivers Seat! is host to numerous speakers, including prominent nephrologists, dialyzors, care partners, and industry leaders. NxStageUsers is an independent patient advocacy organization that is not affiliated with NxStage Medical, Inc.

NxStageUsers appreciates all that NxStage Medical has done and is doing to reinvent home dialysis and allow people to be rehabilitated as was the original mandate of the Medicare program for kidney failure, said Rich Berkowitz, President and Founder of NxStageUsers. Meet-ups like this empower us to further spread the word of the positive impact of home hemodialysis therapy. We look forward to future years of meet-ups and conferences under our new expanded banner of Home Dialyzors United.

It is truly amazing to see our patients and their families independently gather and host a growing conference dedicated to advancing the quality of care of home hemodialysis patients, said Joe Turk, President, North America of NxStage. Our patients have told us that with the freedom to dialyze when and where they want, they feel better, they spend more quality time with family and friends, they travel, and they go back to work. We thank NxStageUsers for championing awareness of the benefits of home hemodialysis, and for giving NxStage the opportunity to participate and speak at this energizing event.

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.
