- Objective:Outcomes used in alcohol brief intervention trials vary considerably. Achieving consensus about key outcomes can enhance evidence synthesis and improve healthcare guidelines. This international, e-Delphi study sought to prioritize outcomes for alcohol brief intervention trials as part of a larger program of work develop an alcohol brief intervention core outcome set.Method:In total, 150 registrants from 19 countries, representing researchers, policymakers, and patients, participated in a two-round e-Delphi study. In Round 1, participants (n = 137) rated 86 outcomes, derived from a review of the literature and a patient and public involvement panel, by importance. In Round 2, participants (n = 114) received feedback on importance ratings for each outcome, and a reminder of their personal rating, before rating the outcomes for importance a second time. Seven additional outcomes suggested in Round 1 were added to the Round 2 questionnaire. We defined consensus a priori as 70% agreement across all stakeholder groups.Results:Seven consumption outcomes met inclusion criteria: typical frequency, typical quantity, frequency of heavy drinking, alcohol-related problems, weekly drinks, at-risk drinking, and combined consumption measures. Others meeting the threshold were alcohol-related injury, quality of life, readiness to change, and intervention fidelity.Conclusions:This is the first international e-Delphi study to identify and prioritize outcomes for use in alcohol brief intervention trials. The use and reporting of outcomes in future alcohol brief intervention trials should improve evidence synthesis in systematic reviews and meta-analyses. Further work is required to refine these outcomes into a core outcome set that includes guidance for measurement of outcomes.

- Objective:The purpose of this study was to characterize recent alcohol brief intervention (ABI) efficacy and effectiveness trials, summarize outcomes, and show how variability in outcomes and reporting compromises the evidence base.Method:A systematic review and narrative synthesis of articles from 10 databases were undertaken (January 2000–November 2017); study selection represented recent, readily available publications. The National Institute of Care Excellence (NICE) Public Health Guideline 24 (Alcohol use disorders: prevention) informed ABI definitions. The review was conducted using Centre for Reviews and Dissemination (CRD) guidance and pre-registered on PROSPERO (CRD42016047185). Seven a priori specified domains were used to classify outcomes: biomarkers, alcohol-related outcomes, economic factors/resource use, health measures, life impact, intervention factors, and psychological/behavioral factors.Results:The search identified 405 trials from 401 eligible papers. In 405 trials, 2,641 separate outcomes were measured in approximately 1,560 different ways. The most common outcomes used were the number of drinks consumed in a week and frequency of heavy episodic drinking. Biomarkers were least frequently used. The most common primary outcome was weekly drinks. By trial type, the most frequent outcome in efficacy and effectiveness trials was frequency of heavy drinking.Conclusions:Consumption outcomes predominated; however, no single outcome was found in all trials. This comprehensive outcome map and methodological detail on ABI effectiveness and efficacy trials can aid decision making in future trials. There was a diversity of instruments, time points, and outcome descriptions in methods and results sections. Compliance with reporting guidance would support data synthesis and improve trial quality. This review establishes the need for a core outcome set (COS)/minimum data standard and supports the Outcome Reporting in Brief Interventions: Alcohol initiative (ORBITAL) to improve standards in the ABI field through a COS for effectiveness and efficacy randomized trials.
