Only 20% of UK centres achieve the recommended 80% target for achieving dialysis of the prevalent dialysis population via permanent access (as opposed to a central venous catheter). This is partly due to the relatively poor maturation rate of newly created fistulas, with as many as 50% of fistulas failing to mature.The Surveillance Of arterioveNous fistulAe using ultRasound study will examine whether a protocolised programme of Doppler ultrasound (US) surveillance can identify, early after creation, potentially correctable problems in those AVFs that subsequently fail to mature.<h4>Methods and analysis</h4>This is a multicentreBMJ openSurveillance arterioveNous fistulAs using ultRasound (SONAR) trial in haemodialysis patients: a study protocol for a multicentre observational study.PMC6661628ACF-2014-14-015PDF-2016-09-065CL-2015-14-002CL-2018-14-008HTA/17/27/1117/27/11Fitzpatrick-Creamer CCrawford KHudson CFoley CDeary AAyorinde TParsons KWeerasinghe TCrane JCarmichael SJRichards JMoinuddin ZPaul SDaniel SSalter TGhazanfar AGee SMotallebzadeh RBadhan RPatel JRowe THossain MHunter JLawman SBond KBagul AOwen WDutta SKerr JWiddup JTrivedi KHyndman SDawson SHopkins VSurendrakumar VBodneck CFleet ASidders ABrand SBajwa AAugustin MSONAR trial groupBolsworth ASelm JVSlater MEadie TBartlett MJerram ALai JBurney KPadayachee SCai PLong JLaing ESomalanka SPotter RBanda JTambyraja ALena MSummers DThomas HKnight SHardy EPugh EEdlin HLochiel RRabuya MBeech APettigrew GTurner STruslove MLagaac RAslam MSmith GWilson ECQuashie-Akponeware MChipurovski IBarnett NKosmoliaptsis VSmith MAnsu KKhosla NLafferty KNgwa-Ndifor NBendle JCheal DEldridge PGibbs PDear KSivaprakasam RTiivas CMorgan MChapman LAllsop KfalseSurveillance arterioveNous fistulAs using ultRasound (SONAR) trial in haemodialysis patients: a study protocol for a multicentre observational study.<h4>Introduction</h4>Arteriovenous fistulas (AVFs) are considered the best and safest modality for providing haemodialysis in patients with end-stage renal disease.
