Abstract

Background: Patients older than 85 years are increasingly admitted to hospital care settings. Despite this, the clinical employment of equations for estimating glomerular filtration rate (GFR) has been scarcely investigated so far in this age group. Our study compared 2 commonly employed equations to estimate GFR, as well as measured 24-hour creatinine clearance (CrCl), in patients aged ≥85 years. Methods: Seventy-three patients consecutively admitted over 4 months to our Internal Medicine Department had an accurate 24-hour urinary collection, as well as serum and urinary creatinine determinations. Measured CrCl was compared with the GFR values estimated by the Modification of Diet in Renal Disease (MDRD) Study and Mayo Clinic quadratic (MCQ) equations. Results: GFR values derived by MDRD and MCQ equations and CrCl significantly differed from each other in the whole sample. CrCl negatively correlated with age (r=-0.389, p
