Overview

Retrospective cohort study investigates survival benefits of preemptive vascular access in hemodialysis patients, suggesting significant mortality reductions.

Key Points

  • This study evaluates how preemptive vascular access affects all-cause mortality in hemodialysis patients.
  • Retrospective cohort study of 489 adult hemodialysis patients from 2009 to 2022.
  • Patients were divided into preemptive and non-preemptive vascular access groups.
  • Inverse probability of treatment weighting was employed for adjusted survival analysis using Kaplan-Meier curves and Cox models.
  • Preemptive access was found in 20.7% of patients; adjusted mortality was 8.9% vs. 18.8%, p < 0.001.
  • Preemptive vascular access led to a 65% reduction in all-cause mortality risk (adjusted HR = 0.35, 95% CI 0.15-0.80).
  • Elderly patients showed greater survival benefits with preemptive placement (p for interaction < 0.05).
