AWOL: AWOL delirium prediction rule
2013AWOL is a four-variable admission risk model for estimating which medical inpatients may develop delirium. It supports prevention planning; it does not detect current delirium.

- Purpose
- Future-risk prediction
- Population
- Adult
- Setting
- General / acute hospital
- Time
- <1 min
- Items
- 4
- Score or threshold
- 0–4 risk score
Format: The instrument records 4 scored items or observations. It is a risk prediction instrument for adult use in General / acute hospital. The stated administration time is <1 min. The published result is recorded using 0–4 risk score.
- Strengths: Predicts who will develop delirium; supports prevention
- Limitations: Prediction, not detection; modest AUC on validation
Evidence
Reported metric context
Prediction rule; AUC 0.81 (derivation), 0.69 (validation). Delirium risk rose 2%→64% across scores.
