A one-year trial of in-center daily hemodialysis with an emphasis on quality of life

Abstract

Background/aims: Hemodialysis is associated with acute changes in several physiologic factors. Previous studies have suggested significant clinical and quality of life (QOL) benefits of daily hemodialysis (DHD) compared with 3 times weekly hemodialysis (CHD). We conducted a prospective trial to evaluate the effects of switching chronic hemodialysis patients to in-center DHD for a 12-month period.

Methods: There were no exclusion criteria. Patients received hemodialysis 6 times per week. The study set a standardized weekly Kt/V (stdKt/V) goal of 3.0. A broad array of clinical parameters was determined. QOL was assessed with multiple instruments.

Results: Eleven subjects completed 12 months and 12 completed 6 months on DHD. Significant changes relative to baseline at 12 months of DHD included decreased BP and improvements in QOL parameters by multiple techniques. 100% of patients at 12 months wished to continue DHD.

Conclusions: DHD offers advantages over CHD with respect to improved QOL and BP control.
