Core Outcome Measures in Effectiveness Trials

Development of a Core Outcome Set and identification of outcome measurement tools for interventions for prevention of stillbirth and care after stillbirth (International Collaboration for Harmonising Outcomes fOr Stillbirth resEarch: ICHOOSE)

General Information

We aim to define a core outcome set for bereavement care interventions following intrauterine death, stillbirth and neonatal loss, that is evidence-based, relevant and appropriate for patients and researchers alike.
1) To identify a list of outcome domains through systematic review of published studies reporting on outcomes following stillbirth, intrauterine death and early neonatal loss
2) To identify a list of potentially important outcome domains reported by women and their partners who have experienced stillbirth, intrauterine death and early neonatal loss to augment the list generated from (1)
3) To prioritise and reach a consensus regarding the most important outcome domains in order to create a Core Outcome Set (COS) in compliance with COMET (Core Outcome Measures in Effectiveness Trials) and CROWN (Core Outcomes in Women’s Health) principles

Systematic review

We will use a mixed methods design consisting of systematic reviews, qualitative research and consensus voting. There will be five distinct phases to this study: 1) Generating a list of all possible outcomes domains following perinatal death using a systematic review of the literature; 2) Identifying additional patient reported outcomes to the list of outcome domains using semi-structured interviews; 3) Prioritisation of outcome domains by key stakeholder groups using a Delphi consensus; 4) A consensus meeting to agree on the final COS and 5) Dissemination of COS results.
