AWOL Score (delirium risk at admission)
AWOL delirium risk score (Douglas 2013): predicts delirium during a medical admission.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Age 80 years or older
- Yes
- Not oriented to place
- Yes
- Nurse-rated illness severity
- Not ill (0)
Result: AWOL 2 of 4 - delirium developed in about 14% of patients at this score.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Observed
- Delirium during the stay: 0 about 2%, 1 about 4%, 2 about 14%, 3 about 20%, 4 about 64%.
- Scope
- Predicts delirium that has not happened yet. Not a delirium screen and no substitute for one; patients already delirious at admission were excluded from the derivation.
What you enter
- Age 80 years or older
- Cannot spell world backward
- Not oriented to place
- Nurse-rated illness severity
How this is calculated
- Items
- Age >= 80, cannot spell world backward, not oriented to place, nurse rating of moderately ill or worse - one point each = 0-4.
