To learn more about your patient’s situation, consider using the following criteria and tools:
DSM criteria. Ask the following 2 questions, which are among DSM-IV-TR criteria for alcohol dependence:
- How many times in the last year have you had a lot more to drink than you intended?
- How many times in the last year have you been drinking in situations where it could have been hazardous, where you could have caused an accident or gotten hurt?
Any answer other than zero to either question is suggestive of a substance use disorder. In exploratory analyses, this approach had positive likelihood ratios of 4.7 to 16 and negative likelihood ratios of 0.05 to 0.30.9,10
Although the above questions refer to alcohol use, they could be revised to learn more about a patient’s use of marijuana or other drugs, as well. (There are few tools for the assessment of drug use, because any illegal or nonmedical use of controlled substances has clear risks of major harm.)
CAGE. Another tool that is effective in assessing alcohol use is the 4-question CAGE—an acronym for Cut down, Annoyed, Guilty, and Eye opener:
- Have you ever felt that you should cut down on your drinking?
- Have people annoyed you by criticizing your drinking?
- Have you ever felt bad or guilty about your drinking?
- Have you ever had a drink in the morning to get rid of a hangover?
One meta-analysis found that a positive CAGE test—ie, a positive response to one or more of the questions—had a sensitivity of 0.85 and a specificity of 0.78 in identifying alcohol dependence in a primary care setting (using DSM criteria as the gold standard).11
AUDIT. This 10-item tool, a longer version of the AUDIT-C (available at http://www.medstudentlearning.com/node/6556), can also be used to determine the extent of alcohol use. This test provides detailed information about the quantity and frequency of alcohol use; however, it does not clearly distinguish between hazardous drinking and alcohol use disorders.12
If the patient is a teen
Assessment methods can be adjusted without difficulty to fit the age of the patient. The National Institute on Alcohol Abuse and Alcoholism has published the Alcohol Screening and Brief Intervention for Youth: A Practitioner’s Guide, available at http://www.niaaa.nih.gov/Publications/EducationTrainingMaterials/Pages/YouthGuide.aspx. The 6-question CRAFFT (for Car, Relax, Alone, Forget, Friends, Trouble) is a validated tool designed to assess adolescents’ use of both alcohol and drugs (http://www.ceasar-boston.org/clinicians/crafft.php).13,14
CASE You give Mr. F the CAGE test, and he answers No to all 4 questions. You conclude that while his drinking may be hazardous, he does not appear to have alcohol abuse or dependence.
FOLLOW UP WITH A BRIEF INTERVENTION
For decades, evidence has shown that brief interventions are often effective in helping hazardous drinkers like Mr. F cut back to safer levels.15-18 In some cases, the impact has been great enough to reduce health care and societal costs for up to 4 years19 and to cut the risk of alcohol-related death by about half.20 As a result, the US Preventive Services Task Force has given a B rating to counseling to reduce alcohol misuse by primary care providers.21 (There is less evidence that brief interventions are effective for drug problems,22 or in settings other than primary care.23)
Treat drug/alcohol problems
If you determine that your patient is engaging in hazardous alcohol or drug use or has a diagnosable substance use disorder, you do not have to drop everything else or treat it as an acute event. What matters is long-term success, which is best achieved by partnering with the patient.
Start by approaching drug and alcohol problems as you would a case of newly elevated blood pressure. Bring up the problem, seeking to engage the patient in addres- sing it.
If he or she does not agree to quit or cut back on drinking the first time you broach the subject, don’t be surprised or discouraged. Keep in mind that patients do not always respond positively to advice about handling chronic medical conditions either, particularly at first, and that you’ll be working together over time. What’s important, in the jargon of the Stages of Change model,24 is to help the patient move from precontemplation to contemplation, and perhaps beyond that to planning or action.
Use motivational interviewing to partner with patients
Motivational interviewing is useful in helping patients change health-related behaviors. The technique, which is not hard to learn or apply, is based on the recognition that a simple shift in style toward a guiding (rather than directive) approach can often reap benefits that are immediately apparent. 25-28
