Background
Poor health-related quality of life (HRQOL) is common in dialysis patients. Increasing treatment frequency improved physical HRQOL in the Frequent Hemodialysis Network trials. The FREEDOM (Following Rehabilitation, Economics and Everyday-Dialysis Outcome Measurements) Study was a 12-month prospective cohort study of short daily home hemodialysis (SDHHD). Interim analysis of the FREEDOM Study indicated that SDHHD led to improvements in HRQOL. We sought to confirm these findings in a final analysis.
Methods
We analyzed HRQOL in intention-to-treat (ITT), conditional ITT (cITT), and as-treated (AT) cohorts. The ITT, cITT, and AT cohorts comprised all patients who initiated SDHHD, those who completed 2 months of follow-up, and those who completed 12 months of follow-up, respectively. HRQOL was measured with the Short Form-36 health survey at baseline, 4 months (if the patient remained on SDHHD), and 12 months (if the patient remained on SDHHD). Patients were censored at death or kidney transplantation. We used adjusted mixed models to analyze changes in HRQOL domains, the physical-composite summary (PCS), and the mental-composite summary (MCS).
Results
The ITT, cITT, and AT cohorts included 487, 408, and 247 patients, respectively. In the ITT cohort, mean PCS increased from 34.8 at baseline to 37.1 at 12 months, while mean MCS increased from 45.8 to 48.0. In the AT cohort, mean PCS increased from 35.5 to 38.6, while mean MCS increased from 48.4 to 50.4. Modeled changes in HRQOL domains between baseline, 4 months, and 12 months are displayed in the table. Changes were uniformly positive.
Conclusion
In a 12-month prospective cohort study, SDHHD was associated with widespread improvements across domains of both physical and mental HRQOL.
