Comparison of AVF Versus AVG in Elderly Patients Starting Dialysis
United States20 participantsStarted 2016-10-06
Plain-language summary
This is a pilot, single-center, randomized trial of 90 subjects to evaluate complication rates and functional status decline in subjects age 65 years and older referred for vascular access placement. Subjects will be randomized to arteriovenous fistula (AVF) (n = 45) versus arteriovenous graft (AVG) (n = 45), placed in a vascular access monitoring protocol, and undergo measurements of functional status including gait speed, grip strength, and self-reported function over 6 months. The primary hypothesis to be tested is that AVF placement will result in a higher proportion of primary access failure as defined by a binary composite primary endpoint of an unsalvageable access or an immature access or a non-functional access measured at 6 months compared to AVG placement. In addition, the study will evaluate whether AVF placement and a greater number of access procedures will result in a greater decline in functional status as measured by the average change over 6 months in gait speed, grip strength, and self-reported function as assessed by the Disabilities in Arm, Shoulder and Hand Survey.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
