The NIAAA single-question screen asks how many times in the past year the patient had ≥4 drinks (women) or ≥5 drinks (men) in a day.¹⁵ The sensitivity and specificity of single-question screening are 82% to 87% and 61% to 79%, respectively, and the test has been validated in several different settings.¹² The AUDIT screening tool, freely available from the World Health Organization, is a 10-item questionnaire that probes an individual’s alcohol intake, alcohol dependence, and adverse consequences of alcohol use. Administration of the AUDIT typically requires only 2 minutes. AUDIT-C¹⁷ is an abbreviated version of the AUDIT questionnaire that asks 3 consumption questions to screen for AUD.

It was found that AUDIT scores in the range of 8 to 15 indicate a medium-level alcohol problem, whereas a score of ≥16 indicates a high-level alcohol problem. The AUDIT-C is scored from 0 to 12, with ≥4 indicating a problem in men and ≥3 a problem in women.

THE CASE

The physician had used the NIAAA single- question screen to determine that Ms. E drank more than 4 beers per day during social events and weekends, which occurred 2 to 3 times per month over the past year. She lives alone and said that she’d been seeing less and less of her boyfriend lately. Her score on the Patient Health Questionnaire (PHQ), which screens for depression, was 11, indicating moderate impairment. Her response on the CAGE questionnaire was negative for a problem with alcohol. However, her AUDIT score was 17, indicating a high-level alcohol problem. Based on these findings, her physician expressed concern that her alcohol use might be contributing to her symptoms and difficulties.

The CAGE questionnaire has lower sensitivity when alcohol intake is lower.

Although she did not have a history of increasing usage per day, a persistent desire to cut down, significant effort to obtain alcohol, or cravings, she was having work troubles and continued to drink even though it was straining relationships, promoting weight gain, and causing abdominal pain.

The physician asked her to schedule a return visit and ordered several blood studies. He also offered to connect her with a colleague with whom he collaborated who could speak with her about possible alcohol use disorders and depression.
