Primary Outcome Measures

Name	Time	Method
Primary fistula patency at 6-months post-creation measured as the interval (in days) between access creation to the earliest of fistula thrombosis, abandonment (except abandonment because of steal or pseudoaneurysm), intervention on the fistula (to re-establish patency), or the time of measurement of patency measured from medical records at 12 months after fistula creation
