What the score means. 0 to 67.

0 to 9: Mild

No withdrawal or mild withdrawal. Medication usually isn’t needed on the score alone; keep reassessing while the risk window lasts.

10 to 18: Moderate

Moderate withdrawal. Most protocols give medication, usually a benzodiazepine, and repeat the score within about an hour.

19 to 67: Severe

Severe withdrawal, with a higher risk of seizures and delirium. Treat promptly, reassess often, and call for a medical review; some protocols move the patient to a higher level of care.
  • Add the ten scores. Nausea and vomiting, tremor, paroxysmal sweats, anxiety, agitation, tactile, auditory and visual disturbances, and headache each score 0 to 7; orientation scores 0 to 4. The total runs from 0 to 67.
  • These bands follow the 2020 ASAM guideline on alcohol withdrawal management: under 10 mild, 10 to 18 moderate, 19 or more severe. The guideline notes that the lines vary in practice.
  • Many hospital protocols and calculators use four bands instead: 0 to 9 absent or minimal, 10 to 15 mild, 16 to 20 moderate, and 21 or more severe. Older summaries put severe at 15 or more.
  • The published form says patients scoring under 10 don’t usually need medication for withdrawal. Protocols start treatment at 8 or at 10, and symptom-triggered protocols set their own thresholds, doses and reassessment intervals.
  • The score needs a patient who can describe their symptoms. For a patient who is sedated, delirious, or can’t communicate, use a sedation-agitation scale such as the RASS and clinical judgment.
  • The total measures withdrawal now. It doesn’t predict seizures or delirium on its own: past withdrawal seizures or delirium, years of heavy daily drinking, and other sedative use raise the risk whatever the score. Tools such as the PAWSS assess that risk.
  • Tremor, sweating and anxiety aren’t specific to alcohol withdrawal. Look for other causes when the picture doesn’t fit.

How to give it, score it, and read it.

Before scoring

Record the context first. It tells you whether the symptoms are likely to be withdrawal, and how much risk sits behind the number.

  • The time of the last drink and the usual amount
  • Breath alcohol: withdrawal can start while the level is still falling in heavy drinkers
  • Past withdrawal seizures, delirium, or hospital stays
  • Other sedatives, and medicines that blunt the signs, such as beta-blockers and clonidine
  • Whether the patient can communicate, and an interpreter when language is the barrier

Avoid: Scoring before you know when the patient last drank. The same total means something different at 8 hours and at 4 days.

Rating the ten signs

Rate each sign as it is now. Tremor, sweats and agitation are scored by watching; nausea, anxiety, headache, the three kinds of disturbance and orientation are scored by asking as well.

  • Use the descriptions on the official form for each level, not a guess between 0 and 7
  • Ask about itching, pins and needles, sounds, and light, and record what the patient says
  • Check orientation the way the form sets out, every time
  • Spend the few minutes the scale needs, at the bedside

Avoid: Rating anxiety or agitation from a glance through the door. Talk with the patient before you score.

Reading the total

Add the ten scores for a total from 0 to 67. Your protocol’s bands decide what follows.

  • Under 10: mild or no withdrawal; medication usually isn’t needed on the score alone
  • 10 to 18: moderate withdrawal; most protocols treat
  • 19 or more: severe withdrawal; treat and call for a medical review
  • Compare with the last score and the hours since the last drink: a rising score in the first two days needs closer checks

Avoid: Acting on bands from another hospital’s protocol. Record the score, and follow the thresholds your own protocol sets.

Symptom-triggered dosing

Medication is given when the score reaches the protocol’s threshold, and the score is repeated to see whether it worked.

  • The drug, dose, route, and time, next to the score that triggered it
  • A repeat CIWA-Ar at the protocol’s interval, often an hour after each dose
  • A running total of the drug over 24 hours
  • Thiamine before any glucose for anyone at risk of Wernicke encephalopathy

Avoid: Symptom-triggered dosing for a patient who can’t report symptoms. A fixed schedule and a different scale suit them better.

Escalation

Some findings need a medical review whatever the total.

  • A seizure, hallucinations, or new confusion
  • A score in the severe range, or one that keeps rising despite doses
  • Pulse, blood pressure, or temperature outside the protocol’s limits
  • High benzodiazepine doses in a short time, or signs of oversedation

Avoid: Waiting for the next scheduled check when the patient looks worse. Score them now.

CIWA-Ar result: moderate withdrawal, symptom-triggered dosing

Medical ward, day 2 of an admission for pneumonia, assessed by the ward nurse

Context

52-year-old man. About 12 beers a day for 10 years. Last drink yesterday at 12:00, 20 hours before this check. Breath alcohol 0.00 at 07:50. Shakes and sweats when he has cut down before; no past withdrawal seizures or delirium. No other sedatives. Talking clearly in English.

Vital signs

08:00: pulse 108, BP 158/94, temperature 37.6 °C, respiratory rate 20, oxygen saturation 95% on room air.

Scores

08:00: nausea and vomiting 2, tremor 3, sweats 3, anxiety 3, agitation 2, tactile 1, auditory 0, visual 1, headache 2, orientation 1. Total 18, moderate, at the top of the range. Previous: 8 at 04:00, below the protocol threshold.

Medication

Diazepam 20 mg by mouth at 08:10 under the ward’s symptom-triggered protocol: 20 mg for a score of 10 or more, repeat the score 1 hour after each dose. Thiamine 100 mg IV at 08:15. Diazepam in 24 hours: 20 mg.

Reassessment and escalation

09:10: nausea 1, tremor 2, sweats 1, anxiety 2, agitation 1, tactile 0, auditory 0, visual 0, headache 2, orientation 0. Total 9, mild; pulse 94, BP 142/86. No further dose. Next CIWA-Ar at 13:10, every 4 hours while under 10. Triggers: a score of 19 or more, hallucinations, confusion, a seizure, or pulse over 120. None met; the medical resident was told of the response at 09:15.

Common mistakes, and how to avoid them.

Scoring a patient who can’t communicate

A sedated, delirious, or non-verbal patient scores low on the signs they can’t report, while withdrawal carries on. Use a sedation-agitation scale instead.

Reading a low score as low risk

Withdrawal seizures can come early, often within 6 to 48 hours of the last drink, and before the score is high. Record past seizures and delirium, and plan around them.

Calling every symptom withdrawal

Tremor, sweating, and confusion also come from infection, low blood sugar, head injury, liver failure, thyroid disease, and other drug withdrawal. Look for them when the picture doesn’t fit.

Recording the total without the times

A score means little without the time of the last drink, the time it was taken, the dose that followed, and the next check. Record all four.

Frequently asked questions.

How do you score the CIWA-Ar?

Rate ten signs: nausea and vomiting, tremor, paroxysmal sweats, anxiety, agitation, tactile disturbances, auditory disturbances, visual disturbances, headache, and orientation. The first nine score 0 to 7 and orientation scores 0 to 4. Add them for a total from 0 to 67. The official form describes what each level looks like.

What does a CIWA-Ar score mean?

Under the 2020 ASAM guideline, a total under 10 is mild withdrawal, 10 to 18 moderate, and 19 or more severe. Many hospital protocols use four bands instead: 0 to 9, 10 to 15, 16 to 20, and 21 or more. Most start medication at 8 or 10. Follow your own protocol’s thresholds.

How often should the CIWA-Ar be repeated?

As often as your protocol says. Symptom-triggered protocols usually repeat it about an hour after each dose, then every 4 to 8 hours once the score stays under the threshold, until it has stayed low for a day or so. Outpatient programs usually check once a day.

Does a low CIWA-Ar score rule out seizures?

No. Withdrawal seizures can happen early, often within 6 to 48 hours of the last drink, sometimes while the score is still low. A past withdrawal seizure or delirium, years of heavy daily drinking, and other sedative use raise the risk whatever the score. Risk tools such as the PAWSS help decide who needs closer care.

How is the CIWA-Ar different from the COWS and the PAWSS?

The CIWA-Ar measures alcohol withdrawal that is happening now. The COWS does the same job for opioid withdrawal. The PAWSS is asked before withdrawal starts, to predict who is likely to have severe or complicated withdrawal. The CIWA-Ar itself is a shorter, revised version of an earlier scale, the CIWA-A.

Can you use the CIWA-Ar if the patient can’t communicate?

Not reliably. Most of the signs depend partly on what the patient tells you. For a patient who is sedated, intubated, delirious, or unable to talk with you, use a sedation-agitation scale such as the RASS and clinical judgment. When language is the barrier, use an interpreter.

Who can give the CIWA-Ar?

Nurses give most CIWA-Ar assessments, along with physicians, nurse practitioners, and trained withdrawal management staff. It takes a few minutes. Training, and occasional checks against a second rater, keep scores consistent between staff.

Is the CIWA-Ar free to use?

Yes. The form published with the scale says it isn’t copyrighted and may be reproduced freely. Get the official form, with the wording for each level, from the 1989 paper by Sullivan and colleagues or from your service’s protocol. The recording template on this page is free to copy or download too.
