CIWA-AR Assessment for Alcohol Withdrawal

3 min read · 6 sections

What is the CIWA-AR?

The Clinical Institute Withdrawal Assessment Alcohol Scale Revised (CIWA-AR) is an instrument used by medical professionals to assess and diagnose the severity of alcohol withdrawal.1 The CIWA-AR is one of the most common methods of treating alcohol withdrawal and is often used by family physicians.2

The CIWA-AR allows physicians to measure the severity of patients’ alcohol withdrawal syndrome, and thus prevent further health complications and treat the withdrawal syndrome accordingly.1

The CIWA-AR can measure 10 alcohol withdrawal symptoms, including:1

  1. Agitation (0-7).
  2. Anxiety (0-7).
  3. Auditory disturbances (0-7).
  4. Clouding of sensorium (0-7).
  5. Headache (0-7).
  6. Nausea/vomiting (0-7).
  7. Paroxysmal sweats (0-7).
  8. Tactile disturbances (0-7).
  9. Tremor (0-7).
  10. Visual disturbances (0-7).

How Should the CIWA-AR Assessment Be Used?

The CIWA-AR assessment should be used by a licensed physician in a professional medical setting. Family doctors may use the CIWA-AR assessment in their practices, along with physicians in residential and outpatient treatment programs.

How is the CIWA-AR Scored?

The CIWA-AR scores on a scale from 0-7 for each symptom and takes less than 2 minutes to complete. By adding up the scores of each 10 symptoms into a total, physicians can determine a severity range for patients’ withdrawal syndrome.

Cumulative scores of less than 8-10 indicate mild withdrawal. Next, scores of 8-15 indicate moderate withdrawal, and scores of 15 or more than 15 indicate severe withdrawal with impending possible delirium tremens.

The Validity & Reliability of the CIWA-AR

Researchers have raised questions within the past decade regarding the legitimacy and reliability of the CIWA-AR. For example, one researcher pointed out that only 3 of the 10 components of the assessment (sweats, tremor, and agitation) can be measured by observation alone, while the other 7 must require discussion with a patient.2

This can be tricky in cases where a patient and physician experience a language barrier, thus preventing the conversations necessary for accurate and precise scoring. Similarly, by having to discuss symptoms with patients who are inherently struggling with alcohol abuse, some patients may not be in the best state of mind to answer questions regarding their condition while being assessed and scored.1,2
