title: Comparison of vascular access use in hemodialysis patients in Isfahan in 2003 and 2013.
abstract: Vascular access (VA) complications are the leading cause of morbidity in the hemodialysis (HD) population and responsible for high health care costs. This study was designed to compare the profile of VA use for HD in Isfahan dialysis units in 2003 and 2013. A cross-sectional observational study was conducted between January and March 2013 on 536 HD patients in seven units. The patients data about VA type, number, survival, and demographic characteristics were collected and compared with the data collected in year 2003 on 320 patients in the same city units. The mean age of patients increased from 51 ± 17 to 58 ± 15 years (P < 0.001). The most common etiology of end-stage renal disease was diabetes mellitus, but the percentage increased in 2013 (P = 0.001).The use of an arteriovenous fistula (AVF) as a first dialysis access fell from 60.6% in 2003 to 35.4% in 2013 (P < 0.001). At the time of study, AVFs were used in 92.2% of patients in 2003 versus 56.5% in 2013 (P < 0.001). The 1, 2, 3 and 5 years AVF survival was 80%, 78%, 73%, and 69%, respectively in 2003 versus 79.4%, 61.2%, 47.3%, and 31.5% in 2013. The AVFs proportions decreased and the tunneled catheters proportions increased while the proportion of temporary catheters decreased in 2013 compared with 2003.
