CIWA Calculator

The Clinical Institute Withdrawal Assessment for Alcohol revised (CIWA-Ar) evaluates ten individual symptom categories. Each category is scored on a standardized numerical scale ranging from 0 (absent or mild) to 7 (severe), with the exception of orientation and clouding of sensorium, which ranges from 0 to 4. The total score is calculated by taking the direct arithmetic sum of all individual symptom ratings: CIWA = Nausea + Tremor + Sweats + Anxiety + Agitation + Tactile Disturbances + Auditory Disturbances + Visual Disturbances + Headache + Orientation.

Consider a patient undergoing early alcohol withdrawal who is assessed by a clinician. The individual ratings recorded are as follows: Nausea and vomiting is scored as 2, tremors as 4, paroxysmal sweats as 3, acute anxiety as 4, and agitation as 2. Furthermore, the patient reports mild tactile disturbances scored as 1, no auditory or visual disturbances (0 each), a mild tension headache scored as 2, and complete orientation to person, place, and time (0). Adding these values together: CIWA = 2 + 4 + 3 + 4 + 2 + 1 + 0 + 0 + 2 + 0, yielding a total score of 18. This cumulative score indicates moderate withdrawal severity, prompting targeted clinical interventions.

Always evaluate the patient consistently using the exact same clinical criteria to ensure score reliability over time. Avoid guessing symptom severity; direct observation paired with clear patient communication is crucial for accurate scoring. Remember that a CIWA score should complement, not replace, comprehensive clinical judgment and vital sign monitoring.
