Comparison of Multi-Round and Real-Time Delphi Survey Methods

Aim: The aim of this trial is to compare a multi-round Delphi survey method with a Real-Time Delphi method on prioritised outcomes included in a core outcome set (COS). This trial is embedded within the COHESION study which is developing a COS for interventions for the treatment of neonatal encephalopathy. Methods: Stakeholders (parents/ caregivers of infants diagnosed and treated with neonatal encephalopathy, healthcare providers and researchers) will be randomised using stratified randomisation to take part in either a multi-round or Real-Time Delphi. Stakeholders will rate the importance of the same set of outcomes in both arms. We will compare the prioritised outcomes at the end of both surveys as well as other parameters such as feedback, initial condition and iteration effects.
