A One-Question Test to Spot Unhealthy Alcohol Use
As a medical term, unhealthy alcohol use can mean anything from risky alcohol consumption to alcohol abuse and dependence. A lot of people meet the criteria for unhealthy alcohol use, but doctors only sometimes screen for it, and more rarely still, accurately identify it in a primary care setting.

Current screening tests, say doctors, are just too long and slow, and thus aren’t used as often as they should be. As a result, doctors miss many alcohol use disorders and opportunities for effective alcohol treatment.
Enter the National Institute of Alcohol Abuse and Alcoholism (NIAAA), which has developed a single-question test for primary care doctors to replace older, longer, and not-often-used alcohol screening questionnaires.
The NIAAA Single-Question Test
The NIAAA’s single-question test asks patients, "How many times in the past year have you had (for men) 5 or more drinks or (for women) 4 or more drinks in a single day?"
To test the newly developed test, the NIAAA asked researchers at Boston Medical Center (BMC) to use the single-question alcohol screen in a primary care environment and report back on their findings.
BMC doctors used the screening test on 286 patients, finding unhealthy alcohol use reported by 31% of patients. Of those, 6% drank alcohol in risky amounts, 13% drank alcohol in risky amounts and had alcohol problems, and 12% exhibited a more serious alcohol use disorder.
Dr. Peter Smith at BMC, the lead study author, reported general success: "The single-question screening recommended by the NIAAA appears to have favorable characteristics." He also acknowledged in his report that the easy-to-administer screening test might increase the frequency of alcohol screening test administration in a primary care setting.
Why Are Alcohol Screening Tests in a Primary Care Setting Important?
Alcohol screening tests in a primary care setting increase the prevalence of alcohol interventions by doctors. These alcohol treatment interventions reduce the use of alcohol at risky levels by people without alcohol dependence and improve overall patient outcomes.
Brief interventions in a health care setting take only a few minutes and have proven to be one of the most cost-effective ways to reduce harmful drinking patterns in those without alcohol dependencies. The single-question test could thus save many millions of dollars in health care costs and improve the health of a vulnerable population of patients.
