Association between Timing of Vascular Access Creation and Mortality in Patients Initiating Hemodialysis: A Nationwide Cohort Study in Japan.

ABSTRACT:

Introduction

The optimal time for vascular access (VA) creation remains controversial.

Methods

We conducted a cohort study using data from the Japanese Society for Dialysis Therapy Renal Data Registry. Adult patients who started receiving hemodialysis in 2007 and had a permanent VA created were included. The exposure of interest was the timing of VA creation, categorized into three groups: early VA creation (defined as creation at least 4 months before hemodialysis initiation), just prior VA creation (creation between 1 and 3 months before hemodialysis initiation), and late VA creation (creation within 1 month of or after hemodialysis initiation). Cox regression analyses were used to compare 1-year all-cause mortality, with late VA creation as the reference group. Owing to t
