How to use this tool

1
Rate each symptom

Score what you observe now, not the worst ever.

2
Keep orientation separate

It scores 0-4, while the other nine score 0-7.

3
Add all ten items

The total, not any single item, sets the band.

4
Act on the band

Higher bands need closer monitoring and medical management.

Formula & worked example

Nine items score 0-7 and orientation scores 0-4, maximum 67. Bands: under 8 minimal, 8-15 mild, 16-20 moderate, over 20 severe.

All items at 0 scores 0 (minimal). Scoring 2 on each of the nine 0-7 items and 1 on orientation gives 19, moderate withdrawal. Scoring 5 on most items exceeds 20, severe.

Limitations — read this before you rely on it

Educational aid only, using the published CIWA-Ar scale. It is not medical advice and does not replace supervised withdrawal care. Alcohol withdrawal can be life-threatening: seek urgent medical help for severe symptoms, confusion, hallucinations, seizures or a high score.
