The Australian and New Zealand Society of Nephrology
The Australian and New Zealand Society of Nephrology is a not-for profit organisation representing the interests of health professionals committed to the prevention and treatment of kidney disease. Through the ANZSN, members support a range of research, education and clinical care initiatives to promote evidenced based practice and quality outcomes for patients in Australia, New Zealand and our region.

Do not prescribe aspirin therapy for primary prevention of cardiovascular disease in patients with stage 1-3 chronic kidney disease as there is no proven benefit and it is associated with increased risk of impaired haemostasis
Chronic kidney disease is a well‐known independent cardiovascular risk factor. Evidence for anti‐platelet therapy indicates that low‐dose aspirin reduces the risk of cardiovascular disease (CVD) by 25–33%, especially in patients with established CVD or those at high risk. In patients with CKD such potential benefits need to be carefully weighed against an increased risk of bleeding. A meta-analysis of serious vascular events and major bleeds in 22 primary and secondary prevention trials involving a combined 120,000 individuals has found that in primary prevention without previous disease, aspirin is of uncertain net value. Moreover, high cumulative exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with an increased risk for rapid CKD progression in the community-based elderly.
The Australian and New Zealand Society of Nephrology (ANZSN) Clinical Policy and Advisory Committee worked with the RACP, as part of the Evolve Program, to develop a long list of low-value practices and interventions that pertain to the specialty. Through extensive research and redrafting, the list was condensed to the top-5 recommendations for reducing low-value practices in nephrology. Dr David Tunnicliffe has been the Lead Fellow on the project.
The list of recommendations was then subject to an extensive review process that involved key College societies with an interest or professional engagement with nephrology as well as health equity. It was then further consulted with other medical colleges through Choosing Wisely Australia. Feedback received in the consultations led to further research and finetuning of the list, which was then finalised and approved by the ANZSN.
- 1 Do not give multiple daily doses of aminoglycoside antibiotics to patients with normal and stable kidney function as the risk of toxicity is less with a single daily dose
- 2 Do not use oral acetylcysteine before giving radiocontrast to patients at increased risk for contrast-induced acute kidney injury
- 3 Do not give routine prophylactic antibiotics to a child after the first urinary tract infection if at low risk of recurrent urinary tract infections

Do not intensively lower HbA1C<6.5% to <8.0% in patients with early (stage 1-3) chronic kidney disease as intense lowering increases the risk of hypoglycaemia and mortality, noting that the individual target depends on factors such as severity of CKD, macrovascular complications, comorbidities, life expectancy and others
