BACKGROUND AND OBJECTIVES: To determine, in a national cohort of incident hemodialysis patients, whether meeting a greater number of National Kidney Foundation Kidney Disease Outcomes Quality Initiative (KDOQI) guideline goals at dialysis initiation was independently associated, in a graded manner, with lower first-year mortality rates. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Patients who initiated hemodialysis between June 1, 2005, and May 31, 2007, in the US were included in this retrospective cohort analysis. Guidelines examined were (1) use of arteriovenous fistula or graft at initiation; (2) hemoglobin > or = 11 g/dl; and (3) albumin at goal. The primary predictor variable was number of guideline goals (zero, one, two, or three) met at dialysis initiation. Cox regression analysis was used to compare time to death, adjusting for baseline characteristics. RESULTS: At dialysis initiation, 59%, 31%, 9%, and 1.6% of patients met zero, one, two, or three guideline goals, respectively (total n = 192,307). After multivariate adjustment, mortality hazard ratios (95% confidence intervals) were 0.81 (0.80 to 0.83) for patients who met one, 0.53 (0.51 to 0.56) for patients who met two, and 0.34 (0.30 to 0.39) for patients who met three guideline goals, compared with patients who met none. Meeting each individual goal was also associated with lower mortality. CONCLUSIONS: These findings suggest a graded association between meeting a greater number of evidence-based guideline goals at dialysis initiation and lower risk of death during the first year on dialysis.
