Objective:

To retrieve, evaluate, and summarize the relevant evidence on preventing the failure of AVF in MHD patients, and to provide evidence-based basis for medical staff to formulate management measures.

Approach:

• Literature Search: Conducted a systematic search for literature on AVF failure management using the '5S' pyramid model of evidence, covering guidelines, expert consensuses, clinical decisions, evidence summaries, best practices, and systematic reviews.
• Evidence Evaluation: Two researchers independently evaluated literature quality, extracted evidence, and integrated findings using the Joanna Briggs Institute evidence pre-rating system.

Key Findings:

• Atotalof15articleswereincluded:6guidelines,4expertconsensuses,4clinicaldecisions,and1systematicreview.Twenty-eightbestevidenceitemswereextractedcoveringPersonnelManagementandTraining,PerioperativeManagement,IntraoperativeManagement,PostoperativeManagement,PunctureCare,andComplicationsManagement.

Interpretation:

The study summarizes evidence on preventing AVF failure and suggests that medical staff should create management plans based on clinical scenarios.

Limitations:

Conclusion:

The study provides a comprehensive summary of evidence for preventing AVF failure in MHD patients, aiming to assist medical staff in formulating management strategies.
