Brief summary
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.
Detailed description
Timely creation of arteriovenous fistula (AVF) is preferred for patients requiring maintenance hemodialysis. Many patients in Egypt initiate hemodialysis with temporary catheters. This hospital-based cross-sectional study will assess the level of knowledge regarding AVF creation among adults with advanced CKD (stage 4-5 not on dialysis and patients on maintenance hemodialysis). A structured interviewer-administered questionnaire will be used to evaluate current awareness in pre-dialysis patients and retrospectively assessed pre-dialysis awareness in current hemodialysis patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pre-dialysis AVF awareness score | Baseline | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion with prior AVF counseling | Baseline | Percentage of participants who report receiving counseling about arteriovenous fistula before initiation of maintenance hemodialysis. |
| Vascular access used at first hemodialysis session | Baseline | Percentage of maintenance hemodialysis patients who started dialysis with arteriovenous fistula versus temporary central venous catheter. |
| Timing of AVF creation | Baseline | Percentage of participants in whom arteriovenous fistula was created before versus after initiation of maintenance hemodialysis. |
| Willingness to undergo AVF creation | Baseline | Percentage of participants willing to undergo arteriovenous fistula creation when indicated. |
| Sources of AVF information | Baseline | Distribution of reported sources of information about arteriovenous fistula (nephrologist, nurse, family, other patients, or media). |
