Core Outcome Set Development

Assigning different levels of importance to components within a composite measure to ensure each contributes appropriately to the overall score, based on patient priorities, expert consensus, or statistical analysis.

A structured tool used to document and track all decisions, evidence, and progress made during the process of defining a domain — ensuring transparency and consistency.

The planned process of sharing research findings with a wider audience — including researchers, practitioners, and the public — to maximize impact and support informed decision-making.

A searchable database of existing and in-development Core Outcome Sets, helping researchers identify what already exists, avoid duplication, and promote transparency.

The surrounding circumstances — social, cultural, economic, or environmental — that may influence an event, outcome, or how results are interpreted. Identifying these factors helps explain differences across settings or populations.

A pre-set level of agreement required among a group to consider a decision reached. Establishing this threshold in advance keeps collaborative processes — such as Delphi surveys — transparent and fair.

A structured map of how key ideas, concepts, or variables in a topic relate to each other. It guides research design, helps explain complex topics, and supports interpretation of findings.

A qualitative research method used to explore and identify the beliefs, experiences, and perspectives of stakeholders on a topic, to inform the development of outcome measures or research tools.

A structured document that describes a specific domain in detail, including its background, key concepts, and supporting evidence. It lays the groundwork for selecting measurement instruments and building Core Outcome Sets.
