This cross-sectional study aims to assess awareness regarding arteriovenous fistula creation among patients with advanced chronic kidney disease, including pre-dialysis patients and those receiving maintenance hemodialysis, at Assiut University Hospital.
Age 18 years or older
Documented chronic kidney disease
CKD stage 4-5 not on maintenance hemodialysis OR currently on maintenance hemodialysis for established CKD
Able to understand and answer the questionnaire
Acute kidney injury without established CKD
Previous kidney transplantation (if considered to affect homogeneity)
Severe cognitive or communication impairment preventing reliable questionnaire completion
Unable or unwilling to provide informed consent
Adults with advanced chronic kidney disease (CKD stage 4-5 not on maintenance hemodialysis or currently receiving maintenance hemodialysis) attending the Nephrology Unit and Maintenance Hemodialysis Unit of Assiut University Hospital.
Case-only
Cross-sectional

Pre-dialysis AVF awareness score
Mean score of knowledge regarding arteriovenous fistula creation (including its use for hemodialysis, need for pre-dialysis preparation, maturation time, arm protection, and differences from catheter) assessed by a structured questionnaire. For patients already on maintenance hemodialysis, awareness will be assessed retrospectively for the period before dialysis initiation.
Proportion with prior AVF counseling
Percentage of participants who report receiving counseling about arteriovenous fistula before initiation of maintenance hemodialysis.
Vascular access used at first hemodialysis session
Percentage of maintenance hemodialysis patients who started dialysis with arteriovenous fistula versus temporary central venous catheter.
Timing of AVF creation
Percentage of participants in whom arteriovenous fistula was created before versus after initiation of maintenance hemodialysis.
Willingness to undergo AVF creation
Percentage of participants willing to undergo arteriovenous fistula creation when indicated.
