Lee J, Min S, Ahn JS, et al. - Researchers examined the efficacy of alcohol-related biochemical markers and Alcohol Use Disorder Identification Test Consumption (AUDIT-C) in suicide attempters who attended their emergency department (ED) based on the gold standard for clinical diagnosis used by psychiatrists for alcohol use disorder. In addition, they sought for a significant standard when correct predictions about alcohol use disorder could be made using these markers. they included 203 individuals (96 men and 107 women) in this work; of these, 88 met the criteria for alcohol abuse or alcohol dependence according to DSM-IV-TR in the past year and were included in the “alcohol use disorder” group and 115 were included in the reference group. Some individuals who did not meet the criteria for the “alcohol use disorder” group were classified as the “risky drinking” group, these comprise men with a weekly alcohol intake of ≥ 14 drinks and women with a weekly alcohol intake of ≥ 7 drinks. In diagnosing alcohol use disorder among suicide attempters in ED, AUDIT-C produced the highest sensitivity, specificity, and accuracy among the biochemical markers. As per the comparison of results, the use of AUDIT-C with or without biochemical markers may assist screen for alcohol use disorder or risky drinking in clinical settings.
