Clinical Institute Withdrawal Assessment for Alcohol (CIWA -A) scale
Last reviewed dd mmm yyyy. Last edited dd mmm yyyy
The Clinical Institute Withdrawal Assessment for Alcohol (CIWA-A) scale is a useful tool to assess severity of AWS (1)
- the scale is not a diagnostic tool as it has not been found to be useful in differentiating between DT and delirium due to medical illnesses (2)
- scale includes 10 common signs and symptoms of alcohol withdrawal with the notable exceptions of pulse rate and blood pressure, which must be a part of the assessment of alcohol withdrawal states
- the 10-item revised form (CIWA-Ar) is described
- CIWA-Ar scale requires limited patient cooperation to evaluate its ten symptoms
- Score grading:
- less than 8 indicate mild withdrawal,
- 8–15 indicate moderate withdrawal (marked autonomic arousal)
- and >15 indicate severe withdrawal and are also predictive of the development of seizures and delirium
- Score interpretation:
- if CIWA-Ar score is <8 pharmacological treatment is not necessary
- if CIWA-Ar score 8-15 pharmacological treatment may be appropriate to prevent the progression to more severe forms of AWS
- pharmacological treatment is strongly indicated in patients with CIWA-Ar score >15
The evaluation of CIWA-Ar score should be repeated at least every 8 hours. In patients with scores >8–10 or requiring treatment, CIWA should be repeated every hour to evaluate the response to treatments
