CIWA-Ar

The CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised) rates the severity of alcohol withdrawal with 10 items. Scores run from 0 to 67. A higher score means more severe withdrawal; scores under 10 usually reflect mild withdrawal.

What it measures

The CIWA-Ar measures how severe alcohol withdrawal is right now. It combines what you observe (tremor, sweating, agitation, orientation) with what the patient reports (nausea, anxiety, headache, sensory disturbances). Repeating it at set intervals shows whether withdrawal is getting better or worse, which helps the team decide how closely to monitor and when to treat under symptom-triggered protocols.

Used for: Adults with known or suspected alcohol withdrawal who can communicate and answer questions. It is less reliable in patients who are intubated, heavily sedated, delirious or unable to talk.

CIWA-Ar interpretation

ScoreResultWhat it means
0–9Mild withdrawalMild or minimal withdrawal. Keep reassessing on schedule, because symptoms can climb over the first 24 to 72 hours after the last drink.
10–18Moderate withdrawalModerate withdrawal. Notify the provider, follow your facility's symptom-triggered protocol and increase the frequency of monitoring.
19–67Severe withdrawalSevere withdrawal with higher risk of seizures and delirium. Escalate care promptly, monitor closely and follow facility protocol.

Versions and other cut-offs: The cut-offs above follow the 2020 ASAM guideline (under 10 mild, 10 to 18 moderate, 19 or more severe). StatPearls uses 8 or less for mild, 9 to 15 for moderate and above 15 for severe, and the original form notes that patients scoring under 10 do not usually need additional medication. Always use the thresholds written in your facility's protocol.

Nursing interventions by CIWA-Ar score

Use these nursing actions as a starting point and follow your facility's alcohol withdrawal protocol and provider orders.

0–9 Mild withdrawal

  • Reassess with the CIWA-Ar per protocol; the ASAM guideline suggests every 1 to 4 hours for the first 24 hours in inpatient care.
  • Once scores stay below 10 for 24 hours, extend reassessment to every 4 to 8 hours if your protocol allows.
  • Check vital signs with each assessment and note the time of the last drink.
  • Encourage non-caffeinated fluids and meals, and record intake and output.
  • Keep the room quiet and evenly lit, and reorient the patient as needed.
  • Notify the provider if the score rises, vital signs worsen or new confusion appears.

10–18 Moderate withdrawal

  • Notify the provider and give symptom-triggered medication per order or protocol.
  • Reassess about 1 hour after each dose, or at the interval your protocol sets, and document the score and response.
  • Monitor vital signs, level of consciousness and signs of over-sedation.
  • Keep the environment calm, low-stimulus and evenly lit; offer frequent reassurance and reorientation.
  • Support hydration and nutrition, and give vitamin supplements as ordered.
  • Apply fall precautions: bed in low position, call light within reach, assist with walking.
  • Escalate if the score keeps rising despite treatment or vomiting prevents oral intake.

19–67 Severe withdrawal

  • Notify the provider right away and follow your escalation pathway; severe withdrawal may need a higher level of care.
  • Start seizure precautions: padded side rails per policy, suction and oxygen at the bedside, bed low and locked.
  • Reassess often, for example every hour or more often per protocol, including vital signs and orientation.
  • Give symptom-triggered medication per order or protocol and watch closely for respiratory depression.
  • Place the patient in a quiet, evenly lit room close to the nursing station, with close observation.
  • Monitor fluid balance and electrolytes as ordered, and support IV fluids and nutrition per orders.
  • Watch for hallucinations, agitation or confusion that suggest delirium, and escalate at once if present.

Interventions follow ASAM Clinical Practice Guideline on Alcohol Withdrawal Management, 2020 (PDF), StatPearls: Alcohol Withdrawal. Your facility's protocol and the provider's orders take priority.

When to use it

How to score it step by step

  1. Confirm the symptoms are likely from alcohol withdrawal and not another cause such as infection, hypoglycemia or head injury.
  2. Take the pulse for one full minute and the blood pressure, and record the time of the last drink if known.
  3. Ask the scripted questions for nausea, tactile, auditory and visual disturbances, anxiety, headache and orientation.
  4. Observe tremor with arms extended and fingers spread, sweating and agitation during the interview.
  5. Score each item on its own scale, add the 10 items for a total from 0 to 67, and document it with the time.
  6. Act on the total according to your protocol and set the time of the next reassessment.

Common mistakes

Example case

Patient. A 52-year-old man admitted for a hip fracture reports drinking about a fifth of whiskey daily. His last drink was 30 hours ago.

Score: 17. A total of 17 falls in the moderate withdrawal range (10 to 18).

Frequently asked questions

What CIWA-Ar score is normal, and what score is high?

There is no true normal, but scores under 10 reflect mild or minimal withdrawal. Under the ASAM guideline, 10 to 18 is moderate and 19 or more is severe. Some sources use 8 or less as mild and above 15 as severe.

Why do some items have no description for 2, 3, 5 and 6?

The published form only defines anchors at 0, 1, 4 and 7 for nausea, tremor, sweats, anxiety and agitation. You can still choose the in-between numbers when the finding falls between two anchors.

How often should I repeat the CIWA-Ar?

Follow your facility's protocol. Reassessment is usually more frequent when scores are higher and spaced out as scores stay low.

Can I use the CIWA-Ar in an intubated or delirious patient?

Not reliably. Several items need the patient to answer questions. Use a tool your facility approves for these patients, such as a sedation or delirium scale.

Is the CIWA-Ar free to use?

Yes. The form states that it is not copyrighted and may be reproduced freely.
