CIWA-Ar Scale Reference
The Clinical Institute Withdrawal Assessment for Alcohol, revised (CIWA-Ar) turns a subjective “how bad is the withdrawal” into a number that drives medication. Knowing what it scores — and what it assumes — keeps symptom-triggered protocols safe.
Educational use only. Score bands and dosing thresholds are facility-specific; always use your institution’s protocol and the official CIWA-Ar tool.

The Ten Items
Each item is scored, most 0–7, with orientation scored 0–4, for a maximum of 67:
- Nausea and vomiting
- Tremor
- Paroxysmal sweats (diaphoresis)
- Anxiety
- Agitation
- Tactile disturbances (itching, pins and needles, bugs)
- Auditory disturbances
- Visual disturbances
- Headache / fullness in the head
- Orientation and clouding of sensorium (scored 0–4)
Severity Bands
| Score | Severity | General Approach |
|---|---|---|
| 0–8 | Minimal / absent | Often no medication; continue scheduled assessment |
| 9–15 | Mild–moderate | Symptom-triggered benzodiazepine per protocol |
| 16+ | Severe | Higher-dose medication, closer monitoring, escalate care; high DTs/seizure risk |
How It’s Used
In symptom-triggered protocols, the nurse scores the patient (commonly every 1–4 hours, more often at higher scores), and the score determines whether a benzodiazepine dose is given and how soon to reassess. This delivers medication when it’s needed and avoids the over-sedation of fixed-schedule dosing — but it depends on accurate, frequent scoring.
Safety Caveats
The CIWA-Ar requires a patient who can communicate — it is unreliable in the intubated, sedated, non-English-speaking-without-interpreter, or cognitively impaired patient. It also doesn’t capture vital-sign instability well, so pair it with hemodynamic monitoring. And a low score doesn’t rule out danger in someone with a prior history of seizures or DTs — history changes the plan regardless of the number.
NCLEX Pearls
- ✦CIWA-Ar guides symptom-triggered benzodiazepine dosing — higher score, more medication and closer monitoring.
- ✦It needs a communicative patient; it’s unreliable when the patient can’t report symptoms.
- ✦Pair scoring with vital signs — rising HR/BP signals escalation the score alone may miss.
