About CAM-ICU
The Confusion Assessment Method for ICU (CAM-ICU) is the most validated tool for delirium detection in critical patients. Should be applied after RASS assessment (not applicable in patients with RASS -4 or -5).
ICU delirium affects 60-80% of mechanically ventilated patients and is associated with higher mortality, prolonged mechanical ventilation time, long-term cognitive decline, and elevated hospital costs. Early detection enables rapid intervention and improved outcomes.
Frequently Asked Questions
What is CAM-ICU?
The Confusion Assessment Method for ICU (CAM-ICU) is a validated tool for detecting delirium in critical patients. It assesses 4 features: acute onset/fluctuating course of mental status, inattention, altered level of consciousness, and disorganized thinking.
How to interpret CAM-ICU results?
CAM-ICU is positive (delirium present) if there is Feature 1 (acute onset/fluctuation) AND Feature 2 (inattention) AND (Feature 3 (altered consciousness) OR Feature 4 (disorganized thinking)). CAM-ICU negative indicates absence of delirium at time of assessment.
What is the clinical importance of CAM-ICU?
ICU delirium is associated with higher mortality (up to 3x), prolonged hospital stay (+40-60%), persistent cognitive decline, and elevated hospital costs. Early detection with CAM-ICU enables rapid intervention with potential to reduce adverse outcomes.
How often should CAM-ICU be applied?
CAM-ICU should be applied at least once per shift (every 8-12 hours) in all ICU patients who are arousable (RASS -3 to +4). It is not applicable in patients in deep coma (RASS -4 or -5).
