Core Outcome Measures in Effectiveness Trials

Outcome Reporting for Brief Intervention Trials (ORBIT)

General Information

The evidence base to assess the efficacy and effectiveness of alcohol brief intervention (ABI) is weakened by variability in measured outcomes and/or by inconsistent reporting. The Outcome Reporting in Brief Intervention Trials (ORBIT) project aims to develop a core outcome set and reporting guidance for use in future trials of ABI in a range of settings.

Through INEBRIA (International Network on Brief Interventions for Alcohol and Other Drugs), an international Special Interest Group was convened to guide the development of this Core Outcome Set (COS). ORBIT will incorporate a systematic review to map outcomes used in efficacy and effectiveness trials of ABI and their measurement properties (using the COnsensus-based Standards for the selection of health Measurement INstruments [COSMIN] criteria). This will support a Delphi study to prioritise outcome domains. Delphi panellists will be drawn from a range of settings and stakeholder groups. The Delphi study will also be used to determine if a single COS is relevant for all settings, or whether a core set with additional setting specific outcomes would be better suited to the needs of the field. A consensus meeting will be held with key stakeholder representation to determine the final COS and the associated guidance for use.

ORBIT will develop a COS for alcohol screening and brief intervention trials, including the domains and recommended instruments. The standardisation of outcome measurement and reporting across ABI studies will support the ongoing development of ABIs and the systematic synthesis of emerging research findings. We will track the extent to which the COS is delivering on this promise through an exploration of the use of the guidance in the decade following COS publication.
