Haemodialysis Vascular Access: Recent Trends From ANZDATA

Dr Kevan Polkinghorne

Monash Medical Centre

ANZSN September 2007


Vascular access anzdata 2000 2005
Vascular Access: ANZDATA 2000 - 2005

  • Vascular access type is an important indicator of quality of care in haemodialysis

  • Collection of vascular access data by ANZDATA commenced in 1999:

    • Initially access in use at the end of survey period collected

    • 31st Oct 2003 – Access at first haemodialysis added

  • Now 6+ years of data available for analysis enabling assessment of trends in vascular access use in the “guidelines era”


International trends
International trends

  • Significant changes in vascular access practice patterns seen in US and Europe

    • USRDS

    • DOPPS





Aims methods
Aims & Methods

Key Questions:

Are the recent trends in international catheter rates seen in ANZDATA?

What are the characteristics of incident patients who use catheters?

Trends in incident vascular access anzdata 2000 2004
Trends in Incident Vascular Access: ANZDATA 2000 -2004

(1) Incident Cohort: Patients who commenced dialysis

within 60 days of the survey period 2000, 2002, & 2004

(2) 6-8 Month Cohort: Patients on dialysis 6-8 months

after commencement 2000, 2001, 2002, & 2003

(3) Prevalent Cohort: All patients on haemodialysis 2000, 2002, 2004, & 2005

Conclusions
Conclusions Kidney Diseases

  • Catheter rates have increased significantly over the last 6 years

  • Rates increased not just in incident patients but also prevalence patients

  • Increased rates not accounted for by differences in comorbidity

  • Trends has continued into 2006 and “similar for PD and HDx units”
