Abstract
Delirium has been recognized in the literature as a significant problem in the care and treatment of the critical care patient. Delirium, a medical disorder that results in the morbidity and mortality of the patients, especially in the elderly, is often misdiagnosed and inappropriately treated. Nurses and other health care professionals need in-depth education about delirium, validated and understandable assessment tools, and astute clinical observational skills. A comprehensive and aggressive clinical management plan that incorporates appropriate pharmacological agents will result in less morbidity and improved long-term outcomes.
