Background: This study provides, to our knowledge, the first national prevalence estimates of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), alcohol use disorders based on a structured, diagnostic instrument for inpatient admissions to US general hospitals. Existing prevalence estimates for inpatient admissions came from studies conducted in 1 or 2 hospitals and therefore do not support national inference.
Methods: A multistage probability sample was designed to represent acute care admissions to nonfederal, short-stay, general hospitals in the contiguous United States; 2040 admissions (1613 males and 427 females) in 90 hospitals participated.
