Selected biological markers may marginally improve the clinical prediction of post-discharge functional decline in hospitalized patients, and may allow to stratify them appropriately. The predictive value of these biomarkers is not fully independent of disease status. Further studies are needed to confirm these results in a cohort representative of older patients admitted through the emergency department.
