A dedicated vascular access program can improve arteriovenous fistula rates without increasing catheters

Area of Science:

• Nephrology
• Vascular Surgery
• Healthcare Management

Background:

• Vascular access (VA) is critical for hemodialysis (HD) patients.
• Optimizing VA type, particularly arteriovenous fistulae (AVF), is crucial for patient outcomes.
• A multidisciplinary approach can enhance VA program effectiveness.

Purpose of the Study:

• To develop and implement a comprehensive multidisciplinary vascular access program.
• To evaluate the program's impact on VA distribution, specifically AVF rates.
• To identify factors associated with AVF use in hemodialysis patients.

Main Methods:

• Retrospective review of incident and prevalent HD patients in 2001 and 2005.
• Data collection included VA type, patient characteristics, and comorbidities.
• Multivariate analysis was used to assess factors influencing AVF use.

Main Results:

• The VA program significantly increased incident AVF rates from 14% to 39% (p=0.04).
• Prevalent AVF rates rose from 60% to 64% (p=0.015).
• Male gender and later year of dialysis initiation were associated with increased AVF use; older age was associated with decreased AVF use.

Conclusions:

• A structured VA program effectively increases functioning fistulas.
• This approach enhances AVF rates without a corresponding rise in catheter use.
• The findings support the implementation of multidisciplinary VA programs in HD units.
