Causes of the delay in creating permanent vascular access in hemodialysis patients

Abstract

Majority of the chronic kidney disease (CKD) patients undergo hemodialysis (HD) with central venous catheter which has multiple complications. This study aims to identify the physicians’ perspectives regarding the reasons of delayed arteriovenous fistula (AVF) creation in the Kingdom of Saudi Arabia to improve the quality of CKD patients’ care and prognosis and prevent complications. A cross-sectional descriptive study was conducted on KSA nephrologists using a questionnaire which includes factors associated with delay in AVF creation, which were categorized into patient, physician, and hospital factors. The optimal timing of starting dialysis was also assessed. In a total of 212 participants, 131 (61.8%) were of consultant level, with the largest numbers being from the Central region (52.4%). The most important patient factors associated with delay in AVF creation were denial of kidney disease or the need of AVF (76.4%), dialysis fears and practical concern (75.9%), and patient refusal (73.1%). The most important physician and hospital factors were insufficient conduction of predialysis care and education (63.7%) and late referral to a nephrologist (56.6%). Participants would create AVF when the patient reaches Stage 4 CKD (69.3%) or Stage 5 (27.4%), and 88.7% of the participants would do so 3–6 months before the anticipated start of HD. Over two-thirds of the participants (68.4%) chose patient as the main factor contributing to the delay of permanent vascular access. A validated approach to patient selection, patient-centered predialysis care, and referral to vascular access creation that could be applied on different types of patients in different regions is required.
