ABSTRACT
BACKGROUND:
Vascular access (VA) failure is a major complication in patients with end-stage renal disease (ESRD) receiving hemodialysis (HD). Thrombosis is the most common cause of VA dysfunction, but the risk factors for VA thrombosis are not well established. While the practice of missing HD sessions (HDs) is associated with increased morbidity and mortality, its impact on VA outcomes is unknown. We evaluated the impact of missing HDs on thrombosis and intervention rates in arteriovenous (AV) accesses.METHODS:
Retrospective review of prevalent HD patients using AV access was done in 2 outpatient HD centers at The Ohio State University over a one-year period.RESULTS:
A total of 142 patients underwent a total of 15,692 HDs, missing 1,602 HDs. Of the 78 patients who met the inclusion criteria, 50 patients missed at least 1 HD. Those with AVF demonstrated no significant association between missing HDs and VA thrombosis. Also, the incidence rate (IR) of intervention was not significantly different for those missing and not missing HDs. However, in the AVG group, those missing HDs were more likely to experience VA thrombosis (OR 9.48, p ≈ 0.041) and had a higher IR of intervention.CONCLUSION:
The practice of missing HDs was prevalent. Those missing dialysis sessions with AVG were more likely to experience VA thrombosis and needed more interventions to maintain VA patency. Our study reveals a differential impact of missing HDs on thrombosis in AVG and AVF, depicting a need to explore mechanistic explanations that may eventually help develop specific preventive strategies.
