The relationship among frailty, delirium and attentional tests to detect delirium: a cohort study.

Background: Few studies explored if frailty predisposes to delirium in hospitalized older patients. The aims of this study were to evaluate if frailty: 1) is independently associated with delirium, and 2) affects the patient's performance in three tests of attention used to detect delirium.

Methods: Data are from a prospective cohort study of patients admitted to an Acute Geriatric Unit (AGU).
