Vascular access for haemodialysis in Scotland - The Scottish Renal ...

Vascular access forhaemodialysis in Scotland(Provisional)Andrew Henderson, Keith Simpson,Gordon Prescott, Joanne Boyd andAlison Severn, on behalf of the ScottishRenal Registry

Introduction• Widely accepted that a nativearteriovenous fistula is the best form ofvascular access for haemodialysis• Central venous lines are associatedwith a higher risk of bacteraemia andhigher mortality• Dhingra et al., 2001; Kidney Int 60:1443• Pastan et al., 2002; Kidney Int 62:620• Xue et al., 2003; Am J Kidney Dis 42:1013

QIS Standards• Standard 4.4:– A minimum of 70% of HD patients have anarteriovenous fistula or vein graft as theirpermanent access– 2002 Peer Review• 3 of 10 adult units reached target– UK Renal Association Survey 4/2005• 5 of 10 adult units reached target

• Standard 4.5:– Permanent catheters are used ashaemodialysis access in a maximum of20% of patients– Met in 3 of 10 units

Questions• How may HD patients with ERF havefistulas, grafts, tunnelled lines etc?• What are the determinants of accesstype?– gender, age, PRD?• Are there large differences in accesstype between units?


Scottish Renal RegistryAudit Census DayConfidential Summary and Data Collection SheetVer 1317 Aug2006The SRR Steering Group has agreed to combine our regular audits of haemoglobin and URR withthe first survey of Vascular Access for patients using hospital or home HD for ERF.Please complete this form for every patient who dialyses in your unit on the census day. Thisincludes patients who are normally registered with another unit but who are dialysing with you onthat day. It also includes all your satellites. An expanded instruction sheet has been sent to eachrenal unit. A copy can be viewed on the SRR Website. Further copies of this document and theinstruction sheet are available on the SRR website or you canphotocopy a blank form.Once completed please give this form to the person responsible for entering data onto the RenalUnit Electronic Patient Record or the Scottish Renal Registry. They will deal with data entry andthen send the form to the SRR office.Please complete all 7 Sections of this form.1. Patient IDName of Parent Renal Unit eg MonklandsLocation of the HD eg Home or Peterhead…Patient Name : SurnameForenameDate of Birth (dd/mm/yyyy)2.

Conclusions• Access is dependent on:– Renal Unit– Sex– Primary Renal Disease• The number of units reaching targets isimproving and is now 70% of adult units

Future Work• Association with haemoglobin anderythropoietin data.• Association with URR and dialysis time data.• Grant applied for to allow prospective datacollection to look more fully at vascularaccess practice and impact on outcomes.
