Abstract
Introduction:
Arteriovenous fistulae remain the gold standard of vascular access in haemodialysis. There is currently no consensus on standardised methods of monitoring arteriovenous fistulae. Assessment techniques and practice remain widely variable. The purpose of this study is to determine whether existing evidence supports physical assessment as an effective tool and a good predictor of arteriovenous fistulae dysfunction to allow for timely intervention and improve outcomes.
Methods:
A literature search was performed using CINAHL, PubMed, Medline and BNI databases and relevant search terms. Studies included were peer-reviewed, published after 2008, in English and related to arteriovenous fistulae only. Six key papers were identified and critically analysed for validity and relevance, in relation to outcomes, assessor experience, training duration and nurses’ ability to perform physical assessment.
Results:
Physical assessment has been shown to be effective in detecting arteriovenous fistulae dysfunction and comparable to technology-based surveillance. Physical assessment techniques generally adopt a ‘look, listen and feel’ approach to identify arteriovenous fistulae dysfunction that includes stenosis, thrombosis, ischaemia and infections. Physical assessment is a skill that can be taught with studies showing that skill-specific training is more effective than experience alone. Cost-effectiveness analysis is lacking.
Conclusion:
The analysis of evidence demonstrates that physical assessment of arteriovenous fistulae is an effective method of detecting arteriovenous fistulae dysfunction and is a skill that can be taught. A structured physical assessment and its implementation may be significant in routine care, but research into the most effective physical assessment techniques and its impact on clinical practice in haemodialysis is required.
