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.
Results An estimated 1.8 million (95% confidence interval, 1.3-2.2 million) annual hospital admissions met the criteria for a current (ie, in the past 12 months) DSM-IV alcohol use disorder. Overall prevalence was estimated to be 7.4% (95% confidence interval, 5.6%-9.1%). Among current-drinking admissions, estimated prevalence was 24.0% (95% confidence interval, 18.7%-29.4%), and males and females had similar rates. Pairwise comparisons showed significant elevations in the prevalence of alcohol use disorders in current-drinking admissions who were younger, black, unmarried, of a lower socioeconomic status, on Medicaid or without health insurance, smokers, or drug users. Prevalence of alcohol use disorders was also significantly highter in current-drinking admissions in hospitals that were government owned, had medical school affiliations, or had a high number of emergency department visits per day.
Conclusions The prevalence of alcohol abuse or dependence in current-drinking admissions was substantial, suggesting that hospitalization offers a unique opportunity to identify alcohol use disorders. Further research is needed to determine factors that may be associated with significant pairwise results, especially for race or ethnicity. We recommend alcohol screening of all hospitalized drinkers, followed, as appropriate, by diagnostic evaluation and referral or intervention.
