What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at 166 older adults (65+) on hemodialysis to compare three types of vascular access: fistulas, grafts, and catheters. The goal was to see which option leads to fewer complications and better quality of life. Researchers tracked how many procedures were needed to keep each access working and measured patient well-being through surveys.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could provide clear guidance on the best type of vascular access for elderly dialysis patients, potentially reducing complications and improving quality of life.
What could go wrong
This is a completed trial with 166 participants, but results may not apply to all elderly patients or settings. The study compares procedures, not drugs, so no direct treatment benefit is tested.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Adult patients aged 65 years or older 2. End-stage renal disease with unlikely recovery of kidney function according to the attending nephrologist 3. Hemodialysis is the intended long-term modality of treatment for end-stage renal disease 4. Fit for vascular access surgery as determined by the local multidisciplinary vascular access team 5a. Expected to start hemodialysis treatment within 6 months at the time of treatment assignment; or 5b. Treated with hemodialysis for 6 months or less at the time of treatment assignment using a tunneled or non-tunneled central venous catheter for vascular access 6\. Planning to remain in one of participating dialysis centers for at least 1 year 7. Suitable vascular anatomy for all types of vascular access based on duplex ultrasound of the arms, defined as: * at least one suitable configuration for an arteriovenous fistula using minimal arterial and venous diameters of 2mm for radiocephalic fistulas and 3mm for brachiocephalic and brachiobasilic fistulas; * at least one suitable configuration for an arteriovenous graft using minimal arterial and venous diameters of 3mm and 4mm, respectively; and * at least one open internal jugular vein for a central venous catheter. Exclusion Criteria: 1. Patent arteriovenous fistula or graft already in place 2. Prior unsuccessful arteriovenous fistula or graft vascular access surgery 3. Kidney transplantation planned within 6 months 4. Metastatic malignancies or other condition associated with a life expectancy of \<6 months, in the opinion of the attending nephrologist 5. Unable to provide informed consent 6. Dusseux risk score \<5, indicating an usually long life expectancy for elderly patients starting hemodialysis treatment (the Dusseux risk score was adapted for patients between 65 and 70 years by assigning -3 points to this age category)
