Hemodialysis (HD) vascular access type affects patients’ hospital admission and mortality rates, according to study findings presented at the 2019 National Kidney Foundation’s Spring Clinical Meetings in Boston.

In a 12-month prospective cohort study, HD access with a central venous catheter (CVC) was significantly associated with a 9-fold increased risk of death and 2-fold increased risk of hospitalization compared with arteriovenous fistula (AVF) access, in adjusted analyses, Janet Diaz-Martinez, a doctoral student at the Florida International University’s Robert Stempel College of Public Health in Miami, and colleagues reported in a poster presentation.

Diaz-Martinez’s team studied 77 HD patients with a mean age of 62.3 years. The cohort was 28.6% female. Patients had been on HD for a median of 6.2 years. The racial or ethnic composition was 31.2% white, 39% black, and 18.2% Hispanic. Vascular access was AVFs in 62 patients and CVCs in 15 patients.

Mean survival times were 11.8 months for patients with AVFs compared with 9.8 months for those with CVCs. The 1-year hospitalization rate was 80% for the CVC patients compared with 40% for the AVF group.

Mean body mass index (BMI) was significantly higher in the AVF than CVC group (27.9 vs 24.7 kg/m2). The association between higher BMI and AVF suggests better nutritional status among HD patients with AVF, the authors concluded.
