CAM-ICU delirium assessment
Delirium screen for ICU patients, including those on ventilators.

Feature 4: disorganized thinking (more than 1 error)
Worked calculation
Your values are highlighted.
- Algorithm
When to use
- ICU patients with RASS −3 or higher, at least once per shift.
Pearls and pitfalls
- Inattention: more than 2 errors on the letters test (squeeze on the letter A).
- If RASS is −4 or −5, reassess later.
Why use
The ICU standard delirium screen.
Delirium = feature 1 AND feature 2 AND (feature 3 OR feature 4)
