To assess the clinical impact on generally healthy older Australians of changing from the 2009 CKD-EPI (CKD-EPI2009) to the 2021 CKD-EPI (CKD-EPI2021) equation for calculating the estimated glomerular filtration rate (eGFR). ⋯ Using CKD-EPI2021 would yield higher eGFR values than the CKD-EPI2009, substantially reducing the proportion of older Australian adults classified as having CKD, without any overall difference in long term health outcomes for people reclassified to less advanced CKD stages. Using the CKD-EPI2021 could markedly reduce the number of referrals of generally healthy older adults to specialist nephrology services.
