Table 1.

Arteriovenous fistula nonmaturation was primarily defined on the basis of whether the patient required central venous catheter use over the study period

Definition of AVF Nonmaturation
1. With any CVC use (n=91): Nonremoval of the CVC >180 days from the date of AVF creation.
2. Without any CVC use (n=41): Inability to initiate HD using the new AVF at the time HD was deemed clinically necessary, or any AVF abandonment/new access creation before HD initiation.
AVF maturation outcomes
Nonmaturation (n=43)
• 14 patients not on dialysis at the time of AVF placement initiated HD with a CVC after AVF placement and did not have CVC removed until >180 days after the date of AVF surgery
• Seven patients not on dialysis at the time of AVF placement had early AVF thrombosis and underwent AVG placement before the initiation of HD
• 21 patients dialyzing with a CVC at the time of AVF placement and did not have CVC removed until >180 days after the date of AVF surgery
• One patient dialyzing with an AVG at the time of AVF placement had the AVF clot 3 months after surgery, and AVF was ultimately abandoned without being used for a new AVF 4 months after the date of AVF surgery		 Successful maturation (n=99)
• 30 patients not on dialysis at the time of AVF placement initiated HD with a mature AVF at a median of 124 days after AVF creation (range 49–568 days) without any CVC usage
• 15 patients not on dialysis at the time of AVF placement initiated HD with a CVC and had the CVC removed ≤180 days after AVF creation
• 41 patients dialyzing with a CVC at the time of AVF placement had the CVC removed ≤180 days after AVF creation
• Two patients on PD initiated HD using the new AVF at 49 and 127 days after AVF creation, respectively
• One patient dialyzing with an AVF at the time of AVF placement initiated HD with the new AVF 69 days after AVF creation
