Run by Soonchunhyang University Hospital · NCT06141798 · Data updated 2026-11-12
This study tests whether doing hemodialysis twice a week instead of three times can help elderly patients with kidney disease feel better and stay out of the hospital.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are elderly patients aged 60 years and older who are starting maintenance hemodialysis and have some residual renal function.
✕Probably not a fit
Patients with severe cardiac issues, liver cirrhosis, active malignancies, or those unable to provide informed consent may not benefit from this study.

What this trial studies
This clinical trial investigates the effects of initiating hemodialysis treatment twice weekly versus the standard thrice weekly regimen in elderly patients with end-stage kidney disease (ESKD). The study aims to assess whether a less frequent dialysis schedule can reduce hospitalization rates and improve quality of life for frail elderly patients who may have multiple comorbidities. By focusing on patients with residual renal function, the trial seeks to validate a potentially safer and more effective approach to renal replacement therapy in this vulnerable population.
Why it matters
Potential benefit: If successful, this study could lead to improved health outcomes and quality of life for elderly patients undergoing hemodialysis.
How similar studies have gone: While the approach of less frequent hemodialysis is being explored, this specific comparison in elderly patients is relatively novel and has not been extensively tested in prior studies.
