Glossary Term
Critical
underscores the need for rigorous, evidence-based methodology in developing Core Outcome Sets (COS). It ensures that every step—from identifying domains to selecting instruments—is systematic, transparent, and grounded in high-quality evidence. By applying this principle, OMERACT strengthens the scientific credibility, reliability, and trustworthiness of its methods and outcomes, producing COS that stakeholders can confidently use.
Examples
OMERACT’s fillable forms for domain and instrument selection embody the Critical Principle in action. These forms guide researchers through a structured, evidence-based process that includes:
- Reviewing the existing literature
- Conducting qualitative work
- Assessing the strengths and weaknesses of available instruments
- Documenting decisions at every stage
This approach ensures that endorsed Core Outcome Sets are scientifically robust, relevant, and meaningful to all collaborators.
