Pitfalls in achieving the Dialysis Outcome Quality Initiative (DOQI) guidelines for hemodialysis access?

The Dialysis Outcome Quality Initiative (DOQI) mandates that 50% of permanent hemodialysis (HD) access be native arteriovenous fistulae (AVFs). Recent reports have shown that when these guidelines are followed, the percentage of new AVFs can exceed DOQI guidelines. From July 1998 to July 2001, 330 HD access procedures were performed in an academic tertiary care center. Patients were categorized into two groups. Group I followed DOQI guidelines and underwent history and physical examination; duplex vein mapping; use of basilic vein transposition; and a postoperative protocol to determine maturation and start needle access in a stepwise progression. Group II had history and physical examination and basilic vein transposition was not used. Patient data were retrospectively reviewed. Overall, 100 (31%) HD shunts were AVFs. Group I (42/183, 23%) had significantly less AVFs (p = 0.005) than group II (58/147, 39%). For first-time placement of HD access, there was no significant difference (p = 0.95) in the percentage of AVFs in group I (26/62, 42%) and group II (29/68, 43%). For patients with prior history of HD access, significantly less AVFs (p <0.001) were placed in group I (16/121, 13%) than in group II (29/79, 37%). Group I had significantly less first-time HDS (P = 0.03) than group II, 34% VS. 46%, respectively. AVF maturation for hemodialysis occurred in 79% of group I and 71% of group II (P = 0.52). There were no significant differences (P > 0.05) when comparing age, gender, and incidence of diabetes between the two groups. AVF formation based largely on duplex vein mapping in group I and lack of basilic vein transposition in group II contributed to the inability to achieve DOQI guidelines. Integration of knowledge and practice among vascular surgeons may help to avoid these pitfalls.
