Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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 | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Formation of a new fistula (including fashioning of proximal neoanastomosis) or radiological salvage procedure measured from medical records at 12 months after fistula creation 2. Fistula thrombosis measured from medical records at 12 months and 5 years after fistula creation 3. Secondary fistula patency at 6- and 12-months post-creation measured from medical records at 12 months after fistula creation 4. Assisted primary fistula patency at 6- and 12-months post-creation measured from medical records at 12 months after fistula creation 5. Primary fistula patency at 12-months post-creation 6. Functional patency and, if functionally patent, time to the event, measured from medical records at 12 months and 5 years after fistula creation 7. Haemodialysis discontinued (due to improvement in renal function, withdrawn from dialysis, switched to peritoneal dialysis, or kidney transplant received) measured from medical records at 12 months after fistula creation 8. Continued dialysis, transplantation, or death measured from medical records at 5 years after fistula creation 9. Primary and secondary fistula patency measured from medical records at 5 years after fistula creation | — |
