a structured tool used to document, monitor, and manage the process of defining a domain. It serves as a central reference point for capturing progress, evidence, decisions, and feedback throughout the domain-definition process. By organizing all relevant information in one place, it ensures transparency, consistency, and accountability when developing or refining a domain.
Example
An OMERACT working group creating a new core domain set uses a Domain Definition Tracking Sheet to record each step of their domain-definition process. The sheet tracks draft definitions, supporting evidence from literature reviews, input from patient research partners, and TAG feedback — ensuring all information is consolidated and easily accessible for reporting and decision-making.
