Recommendations for future core outcome set developers and wider
stakeholders
- Core outcome set developers should integrate methodological research
into their studies to help determine the impact of qualitative methods
upon final core outcome set development
- The feasibility and of global acceptability of core outcome sets needs
further exploration to develop guidance for researchers which inform
stakeholder selection and expectations regarding geographical
representation.
- When discussing the Delphi survey, attrition should be clearly
reported for individual stakeholder groups, the reasons for
participant withdrawal described, and the impact of attrition bias
upon the degree of consensus considered
- Where core outcome sets include a large number of outcomes or when
outcome domains are included, further refinement is required to ensure
they can be implemented within future research.
- Core outcome set developers should commit to supporting the
implementation of their core outcome sets, including engaging with
research funding organizations, individual researchers, and
systematically examining prospective registry records, protocols, and
published research.
