  • Chronic mental illness characterized by inability to limit alcohol ingestion, compulsive drinking, and a negative emotional state when not drinking.
  • Previously separated into alcohol abuse and alcohol dependence, but as of DSM-5, the diagnoses were combined into alcohol use disorder, and subdivided into mild, moderate, or severe.
  • It is estimated that about 6% of adults in the US suffer from alcohol use disorder.

Clinical Features

  • Drinking more or for a longer period of time than intended.
  • Feeling incapable of cutting back on the amount of alcohol consumed.
  • Becoming sick for an extended period of time as a result of drinking too much.
  • Inability to concentrate due to alcohol cravings.

  • Drinking more as a result of a tolerance to alcohol.
  • Experiencing withdrawal symptoms.
Mild = 2-3 features
Moderate = 4-5 features
Severe = 6 or more features

Differential Diagnosis

Ethanol related disease processes


  • A history alone is sufficient to make the diagnosis of alcohol use disorder, however, if a patient presents to the ER, it is important to evaluate for the presence of acute alcohol intoxication, alcohol withdrawal, and co-ingestion with other drugs or toxic alcohols.


  • If the patient is not acutely intoxicated or at risk for alcohol withdrawal, they should be referred to a social worker or their PCP for resources to quit drinking and can usually be discharged safely.
  • Disulfiram can be prescribed as alcohol avoidance therapy, but this should be done by a PCP or psychiatrist treating the patient's addiction.
