The impact of delirium in the intensive care unit on hospital length of stay	2001-11-08		.txt	text/plain	4876	217	40	Patients in the intensive care unit (ICU) are at very high risk for the development of delirium due to factors such as multi-system illnesses and comorbidities, the use of psychoactive medications, and age. While recent studies have selected delirium and pharmacologic issues (which are inter-related) as two of the top three most important target areas for quality of care improvement in vulnerable older adults [13] , nearly all delirium investigations have excluded medical ICU patients who are often receiving prolonged sedation on mechanical ventilators [1, 2, 14, 15, 16, 17] . Two study nurses enrolled patients each morning and recorded baseline demographics, severity of illness data using the Acute Physiology and Chronic Health Evaluation (APACHE) II score [21] , activities of daily living [22] , and risk factors for delirium derived from data in the literature [2, 3, 14, 15, 23, 24, 25, 26, 27] .	./cache/cord-005795-sgi54hq8.txt	./txt/cord-005795-sgi54hq8.txt
