ObjectiveTo determine the factors associated with physician decisions to test for alcohol involvement in adolescents treated in an emergency department (ED) and to examine patient and event characteristics associated with being identified as alcohol positive, either by testing or by clinical examination.MethodsMedical chart reviews were conducted for all adolescent patients (n equals; 9660; age range, 13ndash;19 y) treated over a 1-year period in a Level I regional trauma center/ED.ResultsAmong all 9660 patients in the ED, 298 (3.1percnt;) were identified as alcohol positive by test or clinical examination. Of the 9660 patients, 464 (4.8percnt;) were tested for alcohol, and 49percnt; of these had alcohol-positive test results. Physicians were more likely to order alcohol tests when patients were male, older, injured, and treated during the overnight shift or on weekends. Testing was most common for suicide attempts, motor vehicle crashes, assaults, and intoxication. Patients being treated for an illness or for occupational or athletic injuries were rarely tested. A large proportion of alcohol-related treatment was for intoxicated, uninjured patients, whose profile was different (ie, younger, more often female, with higher blood alcohol concentrations, and admission distributed more evenly across ED shifts).ConclusionsCase detection rates for alcohol involvement may be biased and inflated when based on physician decisions to test for alcohol use. Rates based on comprehensive chart reviews and clinical examination may be better estimates but are also subject to methodologic limitations. Universal screening would yield the most accurate estimates of alcohol prevalence and would provide more accurate guidance to physicians regarding when to test for alcohol use. Universal screening as a clinical standard would help to identify more adolescents who might benefit from additional alcohol use intervention.
