What questions should be asked when assessing a patient with alcohol withdrawal seizures or syndrome?

Key Questions for Assessing Patients with Alcohol Withdrawal Seizures or Syndrome

When assessing a patient with alcohol withdrawal seizures or syndrome, a structured approach using validated screening tools and comprehensive assessment of withdrawal symptoms is essential for determining severity and guiding appropriate treatment.

Validated Screening Tools

• Use the AUDIT (Alcohol Use Disorders Identification Test) as a comprehensive 10-question assessment with high sensitivity and specificity for detecting hazardous drinking and alcohol use disorders 1
• Consider the AUDIT-C, a shortened 3-question version focusing on consumption patterns, when time is limited 1
• The CAGE Questionnaire provides a brief 4-question tool with 85% sensitivity and 89% specificity that asks about attempts to Cut down, Annoyance with criticism about drinking, Guilt about drinking, and using alcohol as an Eye-opener 1, 2

Drinking Pattern Assessment

• Assess quantity and frequency: "How often do you drink?" and "How many drinks do you typically consume on days when you drink?" 1
• Evaluate pattern of consumption: "How often do you have 5 or more drinks (for men) or 4 or more drinks (for women) on one occasion?" 1
• Inquire about drinking context: "In what settings do you typically drink?" and "Do you drink alone or with others?" 1

Withdrawal Symptom Assessment

• Use the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale to assess withdrawal severity - a score >8 indicates moderate AWS and ≥15 indicates severe AWS 2
• Assess timing of last alcohol consumption, as symptoms typically develop within 6-24 hours after the last drink 2, 3
• Evaluate for tremors, increased blood pressure, increased pulse rate, hyperreflexia, irritability, anxiety, headache, nausea, and vomiting as signs of light to moderate withdrawal 2
• Screen for severe withdrawal signs including hallucinations (typically 12-24 hours after last intake), seizures (12-48 hours after last intake), and symptoms of delirium tremens 3

Risk Assessment for Severe Withdrawal

• Identify risk factors for severe withdrawal syndrome: chronic heavy drinking, history of generalized seizures, and history of delirium tremens 4
• Ask about previous withdrawal experiences: "Have you experienced withdrawal symptoms before?" and "Have you ever had seizures or hallucinations when stopping drinking?" 1
• Assess for violence risk: "Have you become aggressive or violent when drinking?" 1

DSM-5 Criteria Assessment for Alcohol Use Disorder

• Assess loss of control: "Have you often found that when you start drinking you end up drinking more than you intended?" 1, 2
• Evaluate unsuccessful attempts to cut down: "Have you tried to cut down or stop drinking, or promised yourself you would, but couldn't keep your promise?" 1
• Ask about time spent drinking: "How much time do you spend drinking or recovering from drinking?" 1
• Assess for cravings: "Have you experienced strong urges or cravings to drink?" 1
• Evaluate role failures: "Has your drinking interfered with your responsibilities at work, school, or home?" 1, 2
• Ask about social/interpersonal problems: "Has your drinking caused problems in your relationships?" 1
• Assess activities given up: "Have you given up or reduced important activities because of your drinking?" 1, 2
• Evaluate hazardous use: "Have you driven a car or operated machinery after drinking?" 1
• Ask about physical/psychological problems: "Have you continued to drink despite physical or mental health problems that might be caused or worsened by alcohol?" 1
• Assess for tolerance: "Do you need to drink more than you used to in order to get the same effect?" 1, 2
• Evaluate withdrawal symptoms: "Do you experience shaking, sweating, nausea, anxiety, or other symptoms when you stop drinking?" 1, 2

Medical Complications Assessment

• Ask about previous medical complications: "Have you experienced any health problems related to your drinking?" 1
• Assess for signs of liver disease, as patients with alcohol-related liver disease are at higher risk for complications 2
• Evaluate nutritional status and vitamin B1 deficiency risk, which is common in alcohol-dependent patients and can lead to serious complications 4
• Ask about other substance use, as many patients with alcohol withdrawal may have polysubstance dependence 4

Common Pitfalls to Avoid

• Avoid focusing exclusively on alcohol consumption without assessing functional impairment and consequences 1
• Don't overlook the risk of Wernicke's encephalopathy, which requires prompt thiamine administration 3
• Be aware that withdrawal symptoms can persist for up to two weeks, not just the initial few days 3
• Remember that patients with severe withdrawal symptoms or at high risk of complications should receive inpatient treatment rather than outpatient management 5
• Don't confuse Subacute Encephalopathy with Seizures in Alcoholics (SESA) with typical alcohol withdrawal seizures, as SESA requires a different diagnostic and management approach 6

Treatment Considerations

• Benzodiazepines are the gold standard treatment for alcohol withdrawal syndrome, particularly for preventing seizures and delirium tremens 2, 7
• Consider carbamazepine or gabapentin for mild symptoms or as adjunctive therapy 7
• Provide daily monitoring for outpatients with alcohol withdrawal syndrome for up to five days after their last drink 7
• Offer to initiate long-term treatment for alcohol use disorder, including pharmacotherapy, in addition to withdrawal management 7
