Stakeholders will review evidence, set priorities and develop guidance for an intervention framework to tackle discrimination experiences and inequalities in health service use. A modified Delphi methodology will be used to generate consensus on an interview framework. Findings from other Projects 1-3 will inform structured discussion among stakeholders. The Delphi process is premised on the assumption that opinions from multiple stakeholders and perspectives is more valid than an individual opinion. The Delphi methodology has been extensively used in health research and offers a reliable method for reviewing evidence and developing guidance and intervention frameworks.
