Overview

Retrospective analysis reveals disparities in AVF procedures for hemodialysis across public and private sectors, indicating regional variations.

Key Points

  • Over nine years, 376,383 arteriovenous fistula procedures were recorded, predominantly in the public sector.
  • In the public sector, 90.57% of AVF procedures occurred, while regional disparities showed higher procedure rates in the Southeast and South.
  • A retrospective population-based analysis employed data from national databases DATASUS and D-TISS, using statistical methods for adjustments.
  • Despite rising dialysis and AVF rates, the ratio of AVFs per 1,000 dialysis patients has shown a declining trend.
