In ICU patients, delirium is commonly associated with which of the following outcomes?

• A. Longer length of stay
• B. Increased mortality
• C. Long-term cognitive impairment
• D. All of the above

Answer: (D)

Delirium in the ICU reflects acute brain dysfunction arising from a mix of critical illness, inflammation, metabolic disturbances, medications, sleep disruption, and immobility. This state often signals a more complicated recovery trajectory and is linked to several adverse outcomes. It tends to prolong recovery, contributing to longer ICU and hospital stays due to more complications, slower mobilization, and delayed rehabilitation. It is also associated with higher short-term and, in many studies, higher mortality, independent of how sick the patient is on admission. Additionally, delirium is connected to longer-lasting cognitive problems after discharge, with some patients experiencing persistent cognitive impairment that affects daily functioning. Because delirium touches multiple aspects of recovery and prognosis, it is commonly associated with all of the above outcomes.
