The application status of vascular access at initiation of hemodialysis in patients with end stage renal disease-a single center study / 中华肾脏病杂志

ABSTRACT

Objective To investigate the types and outcome of vascular access in patients with end stage renal disease (ESRD) initiated hemodialysis (HD), and provide the basis for advancing the proportion of planned HD with arteriovenous fistula (AVF). Methods Clinical data, vascular access types at the initiation of HD, the outcomes of all types of dialysis access and the conversion of renal replacement therapy of ESRD patients who initiated HD in the first affiliated hospital of zhejiang university between January 2009 and December 2011 were retrospectively studied. Results A total of 836 patients were included in our study. Among them 510 were males and 326 were females. The average age was (49.77 ± 17.65) years old. The major primary diseases were primary glomerular disease (72.73%), diabetic nephropathy (11.60%)and hypertensive nephrosclerosis (3.95%). Only 73 patients (8.73%) used AVF as the vascular access at the initiation of HD, another 763 patients (91.27%) used central venous catheter. Six months after the start of dialysis, 542 patients (81.5%) had used AVF as permanent vascular access, 123 patients (18.5%)had used the tunneled cuffed catheter, 54 patients had received a transplant and 55 patients had converted to peritoneal dialysis. The results of logistic regression analysis suggested that being male, patients from outside hangzhou and patients whose glomerular filtration rate were lower than 5 ml·min-1·(1.73 m2)-1 were the risk factors of using central venous catheters at the initiation of HD. Conclusions Only a minority of patients used AVF at the initiation of HD, but most of the other patients switched to AVF within the following six months. Increasing the proportion of AVF as the vascular access of planned HD is still our current goal.
