OBJECTIVES: To compare vascular access in hemodialysis patients >/= 65 years of age with those /= 65 years). DESIGN: A descriptive, longitudinal study with a 1-year follow-up period. METHODS: Following the placement of a permanent vascular access, information was collected by the dialysis nursing staff about the configuration of the access, needle gauge used for cannulation, dialysis prescriptions, diabetic status, and other comorbid disease conditions. Odds ratios (OR) for vascular access thrombosis (VAT) risk were calculate between the two age groups. RESULTS: Comparisons between the two age groups suggest a higher frequency of polytetrafluorethylene (PTFE) grafts in the >/= 65-year-old age group. Peripheral vascular disease (PVD) prevalence was also higher in elders. Oral anticoagulants reduced the risk of VAT in those /= 65-year old with a PTGE graft experienced a higher risk of VAT (OR 3.38, 95% confidence interval 1.43, 8.11) than those in the same age group with an artheriovenous fistula (AVF). CONCLUSIONS: PTFE grafts are used more frequently among geriatric hemodialysis patients, possibly due to the increased prevalence of peripheral vascular disease (PVD). While use of oral anticoagulants is effective in reducing the risk for VAT among those
