Abstract

Chronic kidney disease (CKD) patients who reach end-stage renal disease (ESRD) require early nephrology referral and appropriate vascular access. Arteriovenous fistula (AVF) is the preferred access for hemodialysis (HD). Referral to nephrology of CKD patients starting HD in Jordan and its impact on AVF utilization is unknown. Patients on in-center HD in a large Jordan Ministry of Health dialysis unit were interviewed, and medical records reviewed to assess prior nephrology care and AVF use. Of 104 total patients, 93 met the inclusion criteria. The mean age was 50 ± 16 years, with 44% being females. The average body mass index was 25 ± 5. The cause of ESRD was diabetes mellitus in 28 (30%), hypertension in 28 (30%), and polycystic kidney disease in three (3%). Type of HD access at the initiation of dialysis was central venous catheter (CVC) in 80 (86%) and AVF in 12 (13%). Of the overall group, 50 (54%) were seen by nephrology before initiating dialysis, and of these, 39 patients (78%) were seen >1 year before HD initiation. Of the patients who initiated dialysis with a CVC, 38 (48%) had received prior nephrology care. All 12 patients who initiated dialysis with AVF had received prior nephrology care. Of the 50 patients who received nephrology care before dialysis initiation, 12 patients (24%) had started dialysis with an AVF; in patients without prior nephrology care, all were started with a CVC. In conclusion, our study suggests that a large percentage did not have nephrology care before initiating dialysis. The ones who were seen by nephrology before dialysis were significantly more likely to initiate dialysis using an AVF. A national focus on improving nephrology referral in advanced CKD may allow better utilization of AVF as the method of access at dialysis initiation.
