This study is a prospective analysis of patients admitted to a medical outpatient clinic between August 25, 2003 and July 1, 2006, who experienced AWS. This study is conducted at Copenhagen Hospital Corporation in Copenhagen, Denmark. Patients were divided into two randomized groups: a symptom-triggered treatment versus a fixed-schedule treatment (known) with chlordiazepoxide. They were diagnosed with AWS according to DSM-IV (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition). They were diagnosed with alcohol dependence according to the ICD-10 (International Statistical Classification of Diseases and Health Related Problems).
