Improving access patency: pre-end-stage renal disease strategies

Area of Science:

• Nephrology
• Vascular Surgery
• Healthcare Economics

Background:

• Hemodialysis vascular access is a significant source of morbidity and cost in end-stage renal disease (ESRD).
• Vascular access complications account for substantial healthcare expenditures and hospitalizations in ESRD patients.
• Current access methods present challenges in balancing patency, cost, and patient outcomes.

Purpose of the Study:

• To evaluate the comparative effectiveness and cost-efficiency of different hemodialysis vascular access modalities.
• To identify strategies for improving arteriovenous (AV) fistula formation rates in pre-ESRD patients.
• To address the barriers hindering timely AV fistula creation and placement.

Main Methods:

• Review of existing literature and clinical guidelines, including National Kidney Foundation Dialysis Outcome Quality Initiative recommendations.
• Analysis of evidence regarding fibromuscular dysplasia screening and intervention impact on AV graft longevity.
• Assessment of cost-benefit analyses for AV fistulas versus AV grafts.

Main Results:

• Arteriovenous (AV) fistulas demonstrate superior patency rates and cost-effectiveness compared to native AV grafts.
• Prospective screening for fibromuscular dysplasia with intervention can improve AV graft longevity but incurs significant costs.
• Native AV fistulas remain the preferred access method due to better long-term patency and lower overall costs.
• Lack of timely referral to nephrology is a primary barrier to AV fistula formation.

Conclusions:

• Native AV fistulas are the optimal choice for hemodialysis vascular access, offering superior patency and cost benefits.
• Innovative pre-ESRD strategies are needed to increase AV fistula creation rates.
• Early nephrology referral and prompt AV fistula placement are essential for improving access patency and reducing morbidity.
