Hemodialysis access failure: a call to action

R Hakim1, J Himmelfarb

Summary

Hemodialysis access costs and complications are rising due to delayed referrals and a shift to less durable access types like PTFE grafts. A new program proposes early A-V fistula placement and quality improvement to reduce morbidity and costs.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Biomaterials Science

Background:

  • Rising costs and morbidity associated with hemodialysis access maintenance.
  • Access-related hospitalizations constitute 25% of all admissions in the U.S.A.
  • Epidemiological trends like late referrals and a shift towards PTFE grafts and catheters contribute to access failure.

Purpose of the Study:

  • To address the increasing cost and morbidity of hemodialysis access.
  • To investigate factors contributing to access failure, including patient referral timing and access type selection.
  • To propose a comprehensive program for improving hemodialysis access outcomes.

Main Methods:

  • Analysis of epidemiological trends impacting hemodialysis access.
  • Evaluation of factors influencing the shift from AV fistulae to PTFE grafts and catheters.
  • Proposal of a multidisciplinary quality improvement program for early AV fistula placement and outcome monitoring.

Main Results:

  • Hemodialysis access costs exceed $1 billion annually.
  • Access-related hospitalizations represent a significant burden on healthcare.
  • PTFE grafts and temporary catheters demonstrate higher failure rates compared to AV fistulae.

Conclusions:

  • Early placement of arteriovenous (A-V) fistulae is recommended.
  • A continuous quality improvement, multidisciplinary program is proposed to monitor access outcomes.
  • Further research into biomaterials, pharmacological interventions for stenosis, and clinical treatments is needed to reduce thrombosis and improve access longevity.
