| Summary: | Delirium is a significant neuropsychiatric complication in intensive care unit (ICU) settings, characterized by acute disturbances in attention, awareness, and cognition. The incidence ranges from 30% to 80% among critically ill patients, with the highest rates observed in mechanically ventilated individuals. This syndrome is associated with substantial increases in mortality (hazard ratio [HR] 2.19, 95% confidence interval 1.78–2.70), extended ICU and hospital lengths of stay, and persistent cognitive impairment affecting up to 70% of survivors at 1-year follow-up. Recent evidence has established delirium as an independent predictor of long-term cognitive dysfunction, comparable to moderate traumatic brain injury or mild Alzheimer’s disease. This comprehensive review examines the current understanding of the pathophysiology, risk stratification approaches, evidence-based diagnostic methods, preventive interventions, and management strategies for ICU delirium. Addressing this syndrome through systematic multicomponent interventions represents an essential aspect of critical care medicine with significant implications for patient outcomes and healthcare resource utilization. |
