[Acute confusional state in hospitalized patients].

Delirium or acute confusional status (ACS) is a common mental disorder found in hospitalized patients. A total of 278 patients were evaluated. Of these, 30 (10.8%) developed ACS. The patients who developed ACS were 70 years of age or older, had history of stroke or dementia, as well as impairment in activities of daily living, and required enteral feeding more frequently. The infections and hip fracture were the most frequent reasons for hospitalization. The mortality in patients with ACS was significantly higher than in patients without ACS.
