How to Use This Calculator

Select the appropriate severity score for each of the 10 withdrawal symptoms
Be as objective as possible when rating each symptom
Click Calculate to see the total CIWA-AR score and withdrawal severity
Use the results to guide treatment decisions in consultation with healthcare professionals

Formula Used

CIWA-AR Score = Sum of all 10 symptom scores

Where:

Each symptom is rated on a scale of 0-7 (or 0-4 for some items)
Total score ranges from 0-67
Interpretation: 0-9 (mild), 10-15 (moderate), 16-20 (moderately severe), >20 (severe)

Example Calculation

Real-World Scenario:

A healthcare provider is assessing a 45-year-old patient who is experiencing alcohol withdrawal symptoms after abruptly stopping drinking.

Given:

Nausea and vomiting = 3
Tremor = 4
Paroxysmal sweats = 2
Anxiety = 3
Agitation = 2
Tactile disturbances = 0
Auditory disturbances = 0
Visual disturbances = 0
Headache = 2
Orientation/clouding = 1

Calculation:

CIWA-AR Score = 3 + 4 + 2 + 3 + 2 + 0 + 0 + 0 + 2 + 1 = 17

Result: Total score of 17 indicates moderately severe alcohol withdrawal, which typically requires medication management.

Why This Calculation Matters

Practical Applications

Guiding medication dosing for alcohol withdrawal
Monitoring progression of withdrawal symptoms
Determining appropriate level of care (outpatient vs. inpatient)

Key Benefits

Standardized assessment of withdrawal severity
Objective measurement tool for healthcare providers
Evidence-based approach to withdrawal management

Common Mistakes & Tips

Be as objective as possible when rating symptoms. The CIWA-AR is designed to be a standardized tool, and subjective overestimation can lead to unnecessary treatment. Use the specific descriptions for each score level rather than general impressions.

Alcohol withdrawal symptoms can change rapidly. The CIWA-AR should be reassessed regularly (typically every 1-4 hours) during acute withdrawal to monitor progression and adjust treatment accordingly. A single assessment is not sufficient for management.

Frequently Asked Questions

The CIWA-AR should be used by trained healthcare professionals (doctors, nurses, addiction specialists) when assessing patients experiencing alcohol withdrawal. It is not intended for self-assessment by patients without medical supervision.

During acute withdrawal, the CIWA-AR is typically reassessed every 1-4 hours, depending on the severity of symptoms and the treatment setting. More frequent assessments may be needed for severe withdrawal or when adjusting medication dosages.

Treatment varies by score: mild withdrawal (0-9) may not require medication; moderate (10-15) typically needs benzodiazepines; moderately severe (16-20) requires higher medication doses; severe (>20) often needs intensive monitoring and higher medication doses. Treatment should always be determined by a healthcare professional.
