Abstract
Delirium is a complex psychopathological syndrome with acute onset and fluctuating course. In all hospital setting Delirium occurs in about 15-20% of all general admission. Even if studies report that incidence can vary in different unit. Objective: the aim of the study is to determine , among aged patients admitted in a surgical ward: 1) incidence of Delirium; 2) risk factors predictive for its development. Design: We prospectively followed up a cohort of elederly subjects admitted assessing medical, and psychological factors and using reliable and valid instrument to detect delirium. The setting is a general surgical ward of the University Teaching Hospital. Subjects: 131 Patients, aged 65 years or older consecutively admittted to the ward are recruited. Esclusion criteria are the evidence, at admission, of dementia, psychiatric disorders and severe sensory deprivation (aphasia, bleadness, deafness). 28 subjects do not partecipate (2 refused, 8 do not undergo surgical intervention, 3 died after inervention and 15 was discharged immediatly after oepration). A written consent is obtained. The mean age is 77,41 (+ 7,22; range 66-97); 49 are male and 54 are female.
