Overview

The OPTIMUS study group, coordinated by the EUDA, aims to establish international consensus on monitoring user-reported outcomes for opioid agonist maintenance treatment (OMT).

Through a two-round Delphi study involving 757 participants from 26 countries, a six-domain OMT outcomes questionnaire was developed, covering treatment, physical and mental health, social functioning, substance use, and quality of life.

The tool, endorsed by both professionals and service users, has been translated into 21 languages and refined based on extensive feedback. Feasibility testing, currently ongoing, evaluates acceptability and implementation in OMT services. OPTIMUS promotes harmonised, user-centred measurement of public health relevant OMT outcomes in order to help save and improve service users' lives.
