Discrepancy Between Equations Estimating Kidney Function in Geriatric Care: A Study of Implications for Drug Prescription

Background In older patients, the agreement is low between creatinine clearance estimated with the Cockcroft-Gault equation (eCrCl) and glomerular filtration rate estimated with the Chronic Kidney Disease Epidemiology Collaboration equation (eGFRCKD-EPI). The implications of these discrepancies for drug prescription have so far been assessed only for a few selected molecules.
