Insights
Daily and nocturnal hemodialysis significantly improve urea clearance and patient quality of life compared to conventional hemodialysis. Home quotidian hemodialysis offers clinical benefits and economic advantages, justifying its wider use for kidney disease patients.
Area of Science:
- Nephrology
- Renal Replacement Therapy
- Clinical Outcomes Research
Background:
- Conventional thrice-weekly hemodialysis has limitations in managing end-stage renal disease.
- Quotidian hemodialysis, including daily and nocturnal regimens, offers potential advantages.
- The London Daily/Nocturnal Hemodialysis Study aimed to compare these modalities.
Purpose of the Study:
- To compare the clinical and economic outcomes of quotidian hemodialysis (daily and nocturnal) versus conventional hemodialysis.
- To evaluate improvements in urea clearance, nutrition, anemia, blood pressure, mineral metabolism, and quality of life.
- To conduct an economic analysis of home quotidian hemodialysis.
Main Methods:
- A prospective, comparative, nonrandomized study design.
- Patients assigned to daily (n=11) or nocturnal (n=12) hemodialysis, compared with matched conventional hemodialysis controls (n=22).
- Follow-up duration of 5-36 months, evaluating multiple clinical parameters and economic factors.
Main Results:
- Both quotidian hemodialysis regimens demonstrated superior weekly urea clearance compared to conventional hemodialysis.
- Significant improvements observed in nutrition, blood pressure, volume control, calcium/phosphorus management, and quality of life with quotidian therapy.
- Home quotidian hemodialysis showed substantial cost savings per quality-adjusted life-year.
Conclusions:
- Quotidian hemodialysis regimens are more effective than conventional hemodialysis in enhancing urea clearance.
- Home quotidian hemodialysis provides significant clinical benefits and economic advantages.
- Expansion of home quotidian hemodialysis is clinically and economically justified for end-stage renal disease management.
Abstract:
The London Daily/Nocturnal Hemodialysis Study, a prospective, comparative, nonrandomized study, directly compared outcomes of quotidian (daily) hemodialysis patients with conventional thrice-weekly hemodialysis patients. Patients were assigned to either daily (short-hours) hemodialysis (n = 11) or nocturnal hemodialysis (n = 12) and followed up for 5-36 months; all data were directly compared with matched control patients receiving conventional hemodialysis (n = 22). Outcomes evaluated were adequacy (urea kinetics), nutrition, anemia management, blood pressure and volume control, calcium/phosphorus control, and patient quality of life. In addition, a detailed economic analysis was undertaken. The study showed that both quotidian hemodialysis regimens are more effective than conventional hemodialysis in improving weekly urea clearance. Significant clinical improvements were seen with quotidian therapy in the areas of nutrition (short-hours daily), blood pressure (both), volume control (short-hours daily), calcium/phosphorus control (nocturnal), and quality of life (both). A nonsignificant trend for improvement in anemia management was suggested. The economic analysis showed substantial savings in annualized cost per quality-adjusted life-year in changing from conventional hemodialysis (carried out in-center, in satellite units, or at home) to home quotidian hemodialysis. The substantial clinical benefits of home quotidian hemodialysis, combined with the economic advantage shown by this study, clearly justify its expansion. (The details of this study have recently been published in 11 articles in the American Journal of Kidney Diseases[2003;42(suppl 1)].

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
