ACR Appropriateness Criteria® Dialysis Fistula Malfunction.

Area of Science:

• Nephrology
• Vascular Surgery
• Radiology

Background:

• Dialysis access is critical for end-stage renal disease (ESRD) patient survival and treatment cost reduction.
• Access quality directly impacts dialysis efficacy and patient longevity.
• All dialysis access methods eventually face dysfunction and failure.

Purpose of the Study:

• To systematically evaluate and appraise variants of dialysis access dysfunction.
• To provide evidence-based guidelines for managing thrombotic, nonthrombotic, and infectious access complications.
• To outline diagnostic and interventional strategies for restoring arteriovenous access function.

Main Methods:

• Systematic analysis of peer-reviewed medical literature.
• Application of Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principles.
• Utilizing the RAND/UCLA Appropriateness Method for imaging and treatment procedure evaluation.
• Incorporating expert opinion where literature is lacking or equivocal.

Main Results:

• Dialysis access dysfunction is categorized into thrombotic, nonthrombotic, and infectious complications.
• Restoration strategies include diagnostic imaging, clinical consultation, percutaneous interventions, and surgical management.
• The American College of Radiology Appropriateness Criteria provide a framework for evidence-based management.

Conclusions:

• A systematic, evidence-based approach is essential for managing dialysis access dysfunction.
• Multidisciplinary collaboration and established methodologies ensure appropriate patient care.
• Optimizing dialysis access management improves ESRD patient morbidity, mortality, and quality of life.
