Draft Research Plan for Unhealthy Alcohol Use in Adolescents and Adults, Including Pregnant Women: Screening and Behavioral Counseling Interventions

This opportunity for public comment expired on September 21, 2016 at 8:00 PM EST

Note: This is a Draft Research Plan. This draft is distributed solely for the purpose of receiving public input. It has not been disseminated otherwise by the USPSTF. The final Research Plan will be used to guide a systematic review of the evidence by researchers at an Evidence-based Practice Center. The resulting Evidence Review will form the basis of the USPSTF Recommendation Statement on this topic.

Recommendations made by the USPSTF are independent of the U.S. government. They should not be construed as an official position of the Agency for Healthcare Research and Quality or the U.S. Department of Health and Human Services.

In an effort to maintain a high level of transparency in our methods, we open our draft Research Plans to a public comment period before we publish the final version.

Draft: Proposed Analytic Framework

Text Description is Below the Image

Text Description.

Figure 1 is the analytic framework that depicts the five Key Questions to be addressed in the systematic review. The figure illustrates how screening for unhealthy alcohol use may result in improved behavioral outcomes, including alcohol abstinence, frequency and/or quantity of alcohol use, or other risky behaviors (Key Question 1a) and improved health, social, and legal outcomes (Key Question 1b). Within the screening piece of the framework, there is also a question related to the accuracy of unhealthy alcohol use screening instruments (Key Question 2) and potential harms of screening (Key Question 3). Additionally, the figure illustrates how interventions to reduce unhealthy alcohol use may have an impact on behavioral outcomes (Key Question 4a) and health outcomes (Key Question 4b) and whether these interventions result in any adverse events (Key Question 5).

Draft: Proposed Key Questions to Be Systematically Reviewed

  1. a. Does primary care screening for unhealthy alcohol use in adolescents and adults, including pregnant women, reduce alcohol use or improve other risky behaviors?
    b. Does primary care screening for unhealthy alcohol use in adolescents and adults, including pregnant women, reduce morbidity or mortality or improve other health, social, or legal outcomes?
  2. What is the accuracy of commonly used instruments to screen for unhealthy alcohol use?
  3. What are the harms of screening for unhealthy alcohol use in adolescents and adults, including pregnant women?
  4. a. Do interventions to reduce unhealthy alcohol use, with or without referral, reduce alcohol use or improve other risky behaviors in screen-detected persons?
    b. Do interventions to reduce unhealthy alcohol use, with or without referral, reduce morbidity or mortality or improve other health, social, or legal outcomes in screen-detected persons?
  5. What are the harms of interventions to reduce unhealthy alcohol use in screen-detected persons?

Draft: Proposed Contextual Questions

Contextual questions will not be systematically reviewed and are not shown in the Analytic Framework.

  1. What is the association between reduced alcohol use and health outcomes?
  2. What is the evidence to support current recommendations for alcohol use?

Draft: Proposed Research Approach

The proposed Research Approach identifies the study characteristics and criteria that the Evidence-based Practice Center will use to search for publications and to determine whether identified studies should be included or excluded from the Evidence Review. Criteria are overarching as well as specific to each of the key questions (KQs).

Category Included Excluded
Aim Screening for and treatment of unhealthy alcohol use, with or without addressing other substances or behaviors Studies in which the only aim is targeting another behavior (e.g., drug or tobacco use) (i.e., change in alcohol use is not a stated aim, even if it is a reported outcome)
Condition Unhealthy alcohol use, including:
  • Risky or hazardous use: consumption of alcohol above recommended daily, weekly, or per occasion amounts; consumption levels that increase the risk for health consequences
  • Harmful use: a pattern of drinking that is already causing damage to health; damage may be either physical (e.g., liver damage from chronic drinking) or mental (e.g., depressive episodes secondary to drinking)
  • A diagnosis of alcohol abuse or dependence (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR]) or alcohol use disorder (according to DSM-5)
 
Population All KQs: Adolescents and adults (age ≥12 years)

KQs 1–3: Studies whose participants are not selected on the basis of alcohol use or a related behavior or condition

KQs 4, 5: Studies in which at least 50% of the enrolled sample is recruited via population-based screening

A priori subpopulations at greater risk for unhealthy alcohol use or its consequences will be examined based on the following: age, sex, race/ethnicity, socioeconomic status, pregnancy status, concurrent unhealthy drug use, severity of disorder, and presence of comorbid mental health conditions
  • Treatment-seeking individuals
  • Studies limited to persons with concomitant mental health disorders (e.g., posttraumatic stress disorder, depression)
  • Studies limited to persons presenting in an emergency setting for alcohol-related issues (e.g., motor vehicle injury)
  • Studies limited to other groups not generalizable to primary care (e.g., psychiatric inpatients, persons who are court-mandated to treatment)
Screening KQs 1, 3: Screening for alcohol use using a brief standardized instrument or set of questions that is conducted in person or via telephone, mail, or electronically

KQ 2: Accuracy of screening instruments will be limited to the following instruments, which are most widely used and feasible for application in primary care:

  • National Institute on Alcohol Abuse and Alcoholism (NIAAA) single-item (for adults) or two-item (for adolescents) screening test, or comparable, including the Brief Screener for Tobacco, Alcohol, and other Drugs (BSTAD) (for adolescents)
  • Alcohol Use Disorders Identification Test (AUDIT) and its abbreviated version (AUDIT-C)
  • CAGE questionnaire
  • Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) (for accuracy of detecting alcohol use only)
  • Comorbidity Alcohol Risk Evaluation Tool (CARET) (for older adults)
  • TWEAK and T-ACE (for pregnant women)
  • Studies without any screening instruments or question(s)
  • Laboratory tests
Interventions
  • Counseling (with or without medication*) designed to reduce unhealthy alcohol use, with or without referral
  • Counseling interventions can vary in their approach (e.g., 12-step program, cognitive behavioral therapy, motivational enhancement therapy), specific strategies (e.g., action plans, diaries), delivery method (e.g., face-to-face, Web-based, individual, group-based), length of contact (e.g., brief, extended), and the number of contacts (e.g., single, multiple)
  • Financial incentive
  • Vocational rehabilitation
  • Community-based media or policy interventions
Comparators KQs 1, 3: No screening or usual care

KQ 2: Comparison with reference standard (i.e., structured or semistructured clinical interview)

KQs 4, 5:
  • No intervention
  • Usual care
  • Waitlist
  • Attention control (e.g., intervention is similar in format and intensity but on a different content area)
  • Minimal intervention (e.g., no more than one single brief contact per year, brief written materials such as pamphlets)
Active intervention
