Which clinical feature indicates the need for inpatient detox in alcohol withdrawal?

• A. Seizures
• B. Severe autonomic instability
• C. Lack of safe home environment
• D. Severe autonomic instability, risk of delirium tremens, seizures, intractable medical or psychiatric comorbidity, lack of safe home environment, or inadequate social supports

Answer: (D)

The concept being tested is when alcohol withdrawal is severe enough to require inpatient medical management rather than outpatient care. Inpatient detox is indicated when withdrawal could progress to life-threatening complications or when the patient cannot be safely managed outside a monitored setting. That includes severe autonomic instability (critical blood pressure, heart rate, fever, sweating), risk of delirium tremens, seizures, or the presence of intractable medical or psychiatric comorbidity. It also includes safety concerns like a lack of a safe home environment or inadequate social supports, which make discharge unsafe. The option that lists all of these scenarios together best captures the full range of indications for inpatient care, because it recognizes both the medical risks (severe autonomic symptoms, delirium tremens risk, seizures, comorbidity) and the social/safety factors (home environment and supports) that necessitate closer monitoring and comprehensive treatment. Seizures or severe autonomic instability alone signal the need for inpatient care, but the comprehensive statement is the most accurate and encompassing criterion.
