About

To determine if a protocolized approach to converting hemodialysis central venous catheters (CVC) to arteriovenous fistulae will improve rates of functioning AVF and decrease CVC use.

Full description

In order to receive dialysis, patients require repeated access to their bloodstream. This access can be either via a central venous catheter (CVC) or a surgically created arteriovenous fistula (AVF) or graft (AVG). This is a pilot randomized control trial of prevalent hemodialysis patients with a central venous catheter (CVC), to determine if a systematic approach using an algorithm protocol to convert the CVC to an AVF (arteriovenous fistula) will improve rates of functioning AVF and decrease CVC use. The algorithm (intervention group) will be compared to current practice (control group), a non-standardized approach at the discretion of the caring nephrologist and/or surgeon.
