Home hemodialysis is associated with improved health-related quality of life (HRQoL); however, few studies have examined the impact of in-centre nocturnal hemodialysis (ICNHD) on HRQoL or on dialysis-related symptoms. We sought to determine whether conversion from conventional hemodialysis to ICNHD (8 hours, thrice weekly) improves HRQoL or reduces the burden of dialysis-related symptoms.


Prospective cohort study of conventional in-centre HD patients transitioned to ICNHD between October, 2013, and January, 2016. Health-related quality of life and symptoms associated with dialysis were assessed at baseline using the Kidney Disease Quality of Life-36 (KDQOL-36) survey. Follow-up surveys were completed at 12 months and differences from baseline were assessed using paired t-testing.


Thirty-six patients were enrolled in ICNHD during the study period (69% male, mean age 54). Mean time on dialysis prior to enrollment was 31 months and mean Charlson Comorbidity Index score was 2.19 (range 0-4). Twenty-four patients (67%) were included in final analyses. Table 1 shows changes in the domains of the KDQOL-36. Significant improvements were seen in the “Effects of Kidney Disease” and “Mental Health Composite” domains (increase of 17% and 16%, respectively). Analyses yet to be conducted include an assessment of individual symptoms, as well as a sub-analysis using baseline KDQOL-36 scores to divide the cohort into tertiles.


In-centre nocturnal hemodialysis results in improved HRQoL. Previous studies have shown that patients with the lowest HRQoL at baseline derive the most benefit from home hemodialysis; further analyses will examine whether the same is true for ICNHD. Further studies are needed to determine whether improved HRQoL with ICNHD is associated with improved patient survival.
