Clinic of vascular access: Results after implementing a multidisciplinary approach adding routine Doppler ultrasound

Abstract Background A multidisciplinary approach and Doppler ultrasound (DU) assessment for the creation and maintenance of arteriovenous fistulas (AVF) for haemodialysis can improve prevalence and patency. The aim of this study was to analyze the impact of a new multidisciplinary vascular access (VA) clinic with routine DU. Material and methods We analyzed the VA clinic results from 2014 and 2015, before and after the implementation of a multidisciplinary team protocol (vascular surgeon/nephrologist) with routine DU in preoperative mapping and prevalent AVF. Results We analyzed 345 and 364 patients from 2014 and 2015 respectively. The number of surgical interventions was similar in both periods ( p  = .289), with a trend toward an increase in preventive surgical repair of AVF in 2015 (17 vs. 29, p  = .098). 155 vs. 169 new AVF were performed in 2014 and 2015, with a significantly lower primary failure rate in 2015 (26.4 vs. 15.3%, p  = .015), and a non-significant increase in radiocephalic AVF, 25.8 vs. 33.2% ( n  = 40 vs. 56), p  = .159. The concordance between the indication at the clinic and the surgery performed also increased (81.3 vs. 93.5%, p  = .001). Throughout 2015 fewer complementary imaging test were requested from the clinic (78 vs. 35, p Conclusions Multidisciplinary approach with routine DU can improve VA results, with a decrease in primary failure rate, higher likelihood of radiocephalic AVF, better management of dis-functioning AVF and lower radiological test costs.
