Literature review

We will develop the COSs through five discrete, yet complimentary, phases:
Phase 1: A systematic review of the literature to identify outcomes that have been reported in trials and systematic reviews of trials of interventions for the prevention and treatment of Hypoxic Ischaemic Encephalopathy (HIE);
Phase 2: Semi-structured interviews to obtain women’s, their partner’s, and carers’ attitudes and views on interventions used for the prevention and treatment of HIE. This will then be followed by a consultation exercise to decide which of the patient-guided outcomes should be brought forward to the Delphi Survey phase of the study;
Phase 3: Development of a preliminary COS (informed by Phase 1 & 2) through a three-round web-based Delphi survey with key stakeholders;
Phase 4: Consensus meeting to discuss and agree on the final HIE core outcome sets;
Phase 5: Implementation of a dissemination and implementation strategy for the final core outcome set.
