Age, kidney health link should not be assumed

While it is now known that an eGFR < 60mL/min/1.73m² is common in older people, it is also predictive of significantly increased risk of adverse clinical outcomes and should not be dismissed as age-appropriate, Kidney Health Australia experts say.

Among changes in the latest edition of Chronic Kidney Disease (CKD) Management in General Practice, CKD stage 3 is now divided into two parts – 3a (eGFR 45–59mL/min/1.73m²) and 3b (eGFR 30–44mL/min/1.73m²) – to more accurately reflect risk stratification.

“It is now recommended… that the stages of CKD should be based on the combined indices of kidney function (measured or estimated GFR), kidney damage (albuminuria/proteinuria), and underlying diagnosis (e.g. stage 2 CKD with microalbuminuria secondary to diabetic kidney disease),” the booklet says.
