Gallo P, et al. - Experts undertook a comparison of the prognostic value of different formulas estimating glomerular filtration rate (GFR) in predicting the risk of in-hospital morbidity and mortality within 3 months from discharge in elderly hospitalized patients, using data from the Registro Politerapia Societa Italiana di Medicina Interna (REPOSI). A connection was illustrated between eGFR> 60 ml/min/1.73 m² at admission with a very low risk of mortality during the hospital stay and within 90 days from discharge. On the other hand, an eGFR < 60 ml/min/1.73 m² appeared to be linked with unfavorable outcomes, although with a poor level of accuracy. No difference in predictive power between different equations was found. Physicians were recommended to be aware of the prognostic role of eGFR in a comprehensive assessment of elderly in-patients.
