Previously published data suggests that short daily hemodialysis (2-2.5 hours a day, 6 days a week) may be superior to conventional hemodialysis (3-4 hours a day, 3 days a week) in terms of solute clearance and fluid management. Daily hemodialysis could result in improved dialysis adequacy, improved blood pressure control, decreased cardiac disease (specifically, left ventricular hypertrophy), and decreased mortality. We are working with RRI (Renal Research Institute) as part of a multi-center NIH funded clinical trial studying the potential benefits of short daily hemodialysis versus conventional hemodialysis.
