BACKGROUND AND OBJECTIVES: Maintenance of the vascular access is a crucial factor in hemodialysis, but large studies of factors that are predictive of @entity715 are lacking. DESIGN, SETTING, @entity1 , _ MEASUREMENTS: This prospective, multicenter study investigated a cohort to describe the management of vascular access and establish the influence of @entity417 as a risk factor. The cohort included 1710 @entity1 (aged 64.4 yr; 60% @entity1 ) who were followed every 3 mo at 119 centers during 12 mo. On inclusion, 9.6% had a catheter, 80.3% had a native @entity2548 , and 10.1% had a @entity736 graft. RESULTS: Low baseline hemoglobin increased the risk for vascular access events. The risk was higher with a @entity736 graft and a catheter versus @entity2548 . The multivariate model included @entity455 , previous @entity65 , and noncorrected @entity417 . The likelihood of remaining free of vascular access events 12 mo later was 0.727 (baseline hemoglobin <10.0 g/dl), 0.801 (10.01 to 11.0 g/dl), 0.814 (11.01 to 12.0 g/dl), and 0.833 (>12.0 g/dl), figures similar to those obtained with hemoglobin from the trimester before the event. The Cox model included @entity455 . CONCLUSIONS: Correcting @entity417 did not increase the risk for vascular access-related events, and @entity417 that was resistant to treatment identified a subgroup of @entity1 with higher comorbidity and higher likelihood of a vascular access event.
