Figure 1 is the analytic framework that depicts the five Key Questions (KQ) to be addressed in the systematic review. The figure illustrates how screening for unhealthy alcohol use, followed by behavioral counseling interventions, may result in a reduction of alcohol use, other risky behaviors, and morbidity/morality, as well as improve social and legal outcomes (KQ1). Additionally, the figure illustrates the relationship between screening instruments (including evaluation of their accuracy [KQ2]) and potential harms of screening procedures (KQ3). The figure also shows Key Question 4 that examines how receipt of behavioral counseling interventions may lead to changes in behavioral (e.g., alcohol use) and health outcomes (e.g., morbidity/mortality). Finally, the figure depicts whether behavioral counseling interventions are associated with any harms (KQ5).

1. a. Does primary care screening for unhealthy alcohol use in adolescents and adults reduce alcohol use or improve other risky behaviors?
   b. Does primary care screening for unhealthy alcohol use in adolescents and adults reduce morbidity or mortality or improve other health, social, or legal outcomes?
2. What is the accuracy of selected commonly used instruments to screen for unhealthy alcohol use in adolescents and adults?
3. What are the harms of screening for unhealthy alcohol use in adolescents and adults?
4. a. Do counseling interventions to reduce unhealthy alcohol use reduce alcohol use or improve other risky behaviors in screen-detected individuals?
    b. Do counseling interventions to reduce unhealthy alcohol use reduce morbidity or mortality or improve other health, social, or legal outcomes in screen-detected individuals?
5. What are the harms of interventions to reduce unhealthy alcohol use in screen-detected individuals?

 

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?

Health equity will be considered throughout the review using several approaches. For Key Questions, we will describe the population and intervention characteristics of the included studies to assess the degree to which the evidence is representative of diverse populations. We will also examine evidence separately across age groups (adolescents, young adults, general adult populations, and older adults) and among individuals who are pregnant. In addition, we will explore the extent to which interventions incorporate elements to ameliorate the impact of social risk factors such as housing and food insecurity, financial strain, and other medical needs. We will also examine selected subgroup analyses reported in the included studies to explore whether broad implementation might reduce or exacerbate inequities in unhealthy alcohol use and related morbidity and mortality. Specific analyses of interest will be those stratified by race, ethnicity, sex, gender, and socioeconomic status. Finally, we will include text in the Introduction exploring what is known about how structural and social determinants of health affect risk for unhealthy alcohol use and access to treatment in the United States.

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.

Category Included Excluded
Aim Screening for unhealthy alcohol use and interventions for 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) such that 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 (e.g., according to national guidelines or relevant professional societies)
  • 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 an alcohol use disorder (e.g., according to Diagnostic and Statistical Manual of Mental Disorders [DSM] or International Classification of Diseases [ICD] diagnostic systems)
  
Population All KQs: Adolescents and adults (age ≥12 years), including individuals who are pregnant

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, and at least 50% do not meet criteria for severe alcohol use disorder or alcohol dependence

 Studies in which >50% of participants are:
  • Treatment-seeking individuals (including those responding to recruitment advertising)
  • Persons with concomitant psychotic disorders (e.g., schizophrenia)
  • Persons presenting in an emergency setting for alcohol-related issues (e.g., motor vehicle injury)
  • Other groups not generalizable to primary care (e.g., psychiatric inpatients, persons who are court-mandated to treatment, and incarcerated persons)
  • KQs 4, 5: Persons with severe alcohol use disorder or dependent alcohol abuse (or >50% of the enrolled sample)
Screening KQs 1, 3, 4, 5: Screening for alcohol use using a brief standardized instrument or set of questions that is conducted in person or via telephone, mail, or electronically (not limited to the tools listed for KQ2)

KQ 2: Accuracy of screening instruments will be limited to the following instruments, which include the most widely used and feasible for application in primary care in adolescents, and new versions of previously established instruments adapted to standard drink size and hazardous drinking guidelines in the United States:

  • All populations: U.S. Alcohol Use Disorders Identification Test (USAUDIT), USAUDIT-Concise (USAUDIT-C), version optimized for the United States
  • Adolescents: National Institute on Alcohol Abuse and Alcoholism (NIAAA) two-item screening test, Screening to Brief Intervention (S2BI), Brief Screener for Tobacco, Alcohol, and other Drugs (BSTAD) or comparable
  • Studies without any screening instruments or question(s)
  • Laboratory tests
  • For KQ2 only, other screening tests (including the AUDIT, AUDIT-C using traditional drink size guidelines); the previous review determined that screening tools in adults have adequate accuracy to detect unhealthy alcohol use with high strength of evidence; however, the USAUDIT and USAUDIT-C were under development at the time of the previous review
Interventions Counseling  to reduce unhealthy alcohol use, with or without referral. Counseling interventions can vary in their approach (e.g., 12-step program, cognitive behavioral therapy, or motivational enhancement therapy), specific strategies, delivery method (e.g., face-to-face, electronic, individual, group-based, or telemedicine), duration of contact, and the number of contacts
  • Financial incentive
  • Vocational rehabilitation
  • Community-based media or policy interventions
  • Interventions to prevent initiation of use among nonusers
  • Pharmacotherapy
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  (e.g., comparators with a reasonable expectation of affecting change in alcohol consumption)
Setting KQs 1–3: Population-based screening that takes place in a setting that is applicable to primary care, including: primary care clinics; prenatal clinics; obstetrics/gynecology clinics; specialty medical treatment settings (e.g., diabetes management and dialysis clinics); research clinics; and office, home, or other community settings, including electronic or computer-based screening
