Development of a core outcome set for studies of adenomyosis

Current research in adenomyosis generates multiple and variable outcomes making it difficult to compare different studies. Studies may also focus on outcomes that are not considered relevant to key stakeholders, such as patients with the condition. We propose to collate core outcomes relevant to adenomyosis by identifying the outcomes considered most important to a varied group of stakeholders. A finalised core outcome set should facilitate greater consistency and applicability of future research into adenomyosis

- Semi structured discussion
- Survey
- Systematic review

An international group of stakeholders will be established. Outcomes for adenomyosis will be identified from a systematic review. These outcomes will be entered into a 2-stage Delphi round. Outcomes will be scored by stakeholders on a nine-point Likert scale. Repeated review and consideration of the potential core outcomes will facilitate group convergence on consensus outcomes. These will then be reviewed at a consensus meeting and final core outcomes to be agreed via a nominal group technique. We will also identify measurements for each core outcome. This will all be disseminated to key stakeholders.
