Which scale is used to guide symptom-triggered dosing of benzodiazepines in alcohol withdrawal?

• A. CIWA-Ar
• B. COWS
• C. GCS
• D. DSM-5 criteria

Answer: (A)

The key idea is using a symptom-based tool to tailor benzodiazepine treatment for alcohol withdrawal. The CIWA-Ar, or Clinical Institute Withdrawal Assessment for Alcohol (revised), is designed exactly for this purpose. It quantifies withdrawal severity by scoring ten common symptoms such as tremors, anxiety, sweating, nausea, agitation, perceptual disturbances, and orientation. Each symptom is scored, and the total score guides how much benzodiazepine is given: higher scores mean more aggressive dosing or additional medication, while lower scores indicate milder symptoms and allow dose reduction. This symptom-triggered approach helps ensure patients receive enough medication to prevent progression to severe withdrawal or seizures, without overdosing.

Other scales don’t fit this use. COWS is for identifying opioid withdrawal, not alcohol withdrawal. GCS assesses level of consciousness, mainly in head injury or altered mental status, not withdrawal severity. DSM-5 criteria outline diagnostic criteria for alcohol use disorder, not the acute management of withdrawal symptoms.
