Abstract

More frequent hemodialysis (5 or more times weekly, both short during the day and long overnight) has been shown to improve patient well-being, reduce symptoms during and between treatments, and have beneficial effects on clinical outcomes. Because of the relatively small patient sample sizes, there are little or no data on mortality from any single study at this time. This study compares survival in 117 U.S. patients treated by short-daily hemodialysis in 2003 and 2004, with patients reported in the 2003 data from the United States Renal Data System (USRDS). Expected mortality was calculated from the USRDS and compared with observed actual mortality. The standardized mortality ratio (SMR) was used to adjust for differences in patient age, sex, race, and cause of renal failure. The SMR for the short-daily hemodialysis patients was 0.39, statistically significantly better (p < 0.005) than data from the overall U.S. population of hemodialysis patients and indicating that daily hemodialysis patients had a 61% better survival. Patients treated by short-daily hemodialysis have a better survival rate than comparable populations treated by conventional hemodialysis.
