Delirium is typically associated with which prognostic implications?

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

Answer: (D)

Delirium in the ICU is a sign of acute brain dysfunction that carries widespread prognostic meaning. It tends to prolong hospital stays because delirious patients often have slower recovery, more complications, and require extended monitoring and care. It is also linked to higher mortality both during the hospital stay and afterward, reflecting the overall severity of illness and the added risk delirium brings to physiologic stability. In addition, delirium is associated with longer-term cognitive problems; many survivors experience lasting difficulties with attention, memory, and executive function that can persist for months and affect daily functioning. Because delirium can influence short-term outcomes and long-term cognitive health, it commonly carries implications across all these domains.
