CIWA Scoring for Alcohol Withdrawal Management

Understanding the CIWA Assessment

The Clinical Institute Withdrawal Assessment for Alcohol (CIWA) scoring system helps evaluate the severity of alcohol withdrawal syndrome (AWS), plan treatment, and facilitate communication between healthcare providers 1
The assessment focuses on symptoms of autonomic nervous system activation, gastrointestinal symptoms, and cognitive deficits 3
High CIWA scores may also be seen in conditions similar to AWS, such as anxiolytic withdrawal, anxiety disorder, sepsis, hepatic encephalopathy, and severe pain 1, 3

CIWA scores ≥8 indicate moderate withdrawal requiring intervention, while scores ≥15 indicate severe withdrawal with higher risk of complications 4
For moderate to severe withdrawal (CIWA ≥8), administer benzodiazepines using a symptom-triggered approach 3, 4
Long-acting benzodiazepines (chlordiazepoxide, diazepam) are recommended for seizure prevention 3
For patients with liver dysfunction, advanced age, or respiratory issues, use lorazepam instead 4

For mild-moderate withdrawal (CIWA 8-14), diazepam 5-10mg every 6-8 hours as needed may be administered 4
For severe withdrawal (CIWA ≥15), more aggressive benzodiazepine dosing may be required 4
Consider lorazepam 6-12mg/day for patients with severe AWS, advanced age, head trauma, liver failure, respiratory issues, or obesity 3

Inpatient treatment is recommended for patients with serious complications such as delirium or seizures 3
Inpatient treatment is also recommended for patients with a history of severe withdrawal symptoms 5
Outpatient treatment may be more cost-effective for patients without these risk factors, with similar abstinence rates at 6 months 1

Administer thiamine (100-300mg/day) to all patients with AWS to prevent Wernicke encephalopathy 3, 4
Maintain thiamine supplementation for 2-3 months following resolution of withdrawal symptoms 3
Psychiatric consultation is recommended for evaluation, acute management, and long-term abstinence planning 3
