The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is a specific diagnostic tool used by clinicians to quickly and accurately screen for delirium in critically ill patients, including those who are non-verbal or intubated. Unlike other tools that might assess general confusion, the CAM-ICU is tailored for the unique environment of the intensive care unit. It is based on a structured, four-feature assessment that can be completed in just a few minutes, making it highly practical for daily use. By systematically checking for features like acute mental status changes, inattention, disorganized thinking, and an altered level of consciousness, the tool provides a standardized way to identify delirium, which is crucial for improving patient outcomes.
