Interactive Decision Tree
Algorithm Steps
- ▶Start
Alcohol Withdrawal Risk
Patient with heavy alcohol use stopping/reducing
- ●Action
Risk Assessment
Identify high-risk patients
- History of withdrawal seizures or DT
- Daily heavy drinking >10 years
- Prior complicated withdrawals
- Concurrent illness/surgery
- Age >65
- ●Action
CIWA-Ar Assessment
Score 0-67 based on 10 items
- Nausea/vomiting (0-7)
- Tremor (0-7)
- Sweating (0-7)
- Anxiety (0-7)
- Agitation (0-7)
- Tactile disturbances (0-7)
- Auditory disturbances (0-7)
- Visual disturbances (0-7)
- Headache (0-7)
- Orientation/clouding (0-4)
- ◆Decision
CIWA-Ar Score Interpretation
Guides treatment intensity
- 0-8: Minimal withdrawal
- 9-15: Mild withdrawal
- 16-20: Moderate withdrawal
- >20: Severe withdrawal
- ●Action
Minimal (CIWA 0-8)
Supportive care, monitoring
- No pharmacotherapy needed
- Supportive care
- Reassess CIWA q4-8h
- Thiamine 100mg daily
- ●Action
Supportive Measures (All Patients)
Essential adjuncts
- Thiamine 100mg IV/IM x3 days before glucose
- Folate 1mg daily
- Electrolyte repletion (Mg, K, Phos)
- IV fluids if dehydrated
- Quiet, well-lit environment
- Fall precautions
- ●Action
Monitoring
Frequency based on severity
- CIWA q1h during active treatment
- CIWA q4h once stable
- Vitals q2-4h
- Watch for aspiration if sedated
- ✓Outcome
Disposition Planning
After withdrawal managed
- Addiction medicine/psychiatry consult
- Consider naltrexone, acamprosate
- Outpatient treatment referral
- Social work involvement
- ●Action
Mild (CIWA 9-15)
Consider PRN benzos
- May observe without medication
- Or PRN benzos if high risk
- Reassess CIWA q2-4h
- Thiamine + multivitamin
- ●Action
Moderate (CIWA 16-20)
Symptom-triggered benzos
- Lorazepam 2-4mg or Diazepam 10-20mg
- Repeat q1h until CIWA <10
- CIWA q1-2h during active treatment
- Thiamine 100mg IV before glucose
- ●Action
Benzodiazepine Options
Choose based on patient factors
- Lorazepam: 2-4mg PO/IV q1h PRN (liver disease, elderly)
- Diazepam: 10-20mg PO/IV q1h PRN (active metabolite, longer)
- Chlordiazepoxide: 50-100mg q6h (oral, outpatient)
- Symptom-triggered > fixed-dose in most cases
- ●Action
Severe (CIWA >20)
Aggressive treatment required
- Higher/more frequent benzo doses
- Consider ICU monitoring
- May need phenobarbital adjunct
- Watch for respiratory depression
- ⚠Warning
⚠️ Delirium Tremens (DT)
Medical emergency - mortality 5-15% untreated
- Onset 48-72h after last drink
- Confusion, hallucinations, autonomic instability
- ICU admission recommended
- High-dose IV benzos
- Consider propofol/dexmedetomidine if refractory
- ⚠Warning
⚠️ Withdrawal Seizures
Peak 12-48h after last drink
- Usually generalized tonic-clonic
- Treat with IV benzo (lorazepam 4mg)
- May herald DT development
- Not typically chronic epilepsy

Clinical Safety Information
Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- CIWA requires patient cooperation (may not be usable if intubated/obtunded)
- Does not replace clinical judgment
- Concurrent medical conditions may affect presentation
- Drug dosing should follow institutional protocols
- Delirium tremens is medical emergency
