Influence of arteriovenous fistula on daily living behaviors involving the upper limbs in hemodialysis patients: a cross-sectional questionnaire study

Abstract

Background

Arteriovenous fistulae can restrict daily living behaviors involving the upper limbs in hemodialysis patients, but no studies have investigated the detailed effects of an arteriovenous fistula on routine life activities. Accordingly, many medical caregivers are unable to explain the effects of an arteriovenous fistula on daily life, particularly during non-dialysis periods, because they cannot observe them directly.

Methods

Thirty outpatients undergoing hemodialysis at 2 facilities scored the difficulty due to an arteriovenous fistula in performing 48 living behaviors during non-dialysis and 10 behaviors during dialysis into 5 grades in a comprehensive questionnaire survey. These behaviors were selected based on an open-answer pre-questionnaire administered to the 30 patients beforehand. The scores were also compared between dominant arm and non-dominant arm arteriovenous fistula groups.

Results

During non-dialysis, the difficulty scores of behaviors restricted out of concern for arteriovenous fistula obstruction (wear a wristwatch, hang a bag on the arm, carry a baby or a dog in the arms, wear a short-sleeved shirt, etc.) increased. The difficulties of “wear a wristwatch” and “hang a bag on the arm” were significantly higher in the non-dominant arm arteriovenous fistula group (both P < 0.05). In contrast, scores related to motor function (write, eat or drink, scratch an itch, etc.) increased remarkably during dialysis because of connection of the arteriovenous fistula to the dialysis machine. The difficulties of “write” and “eat or drink” were significantly higher in the dominant arm arteriovenous fistula group (both P < 0.05).

Conclusions

Several key daily living behaviors restricted by an arteriovenous fistula were identified in this questionnaire survey. These results will be useful for pre-operative explanation of arteriovenous fistula surgery and arm selection in end-stage renal disease patients.
