The evaluation of frequency and predictors of delirium and its short-term and long-term outcomes in hospitalized older adults'.

Delirium is quite frequent in geriatric inpatients and is associated with high in-hospital and post-discharge mortality risk and long-term functional dependency.

Emergency admission, pre-hospitalization functional dependency, and more general psychopathological symptoms are independently associated factors.

Hence, earliest identification and treatment with early implementation of rehabilitation services is warranted.
