Round 1 content includes: the respondent’s clinical role; a list of outcomes to be scored, ordered alphabetically; and an option for a participant to add any additional outcomes and to provide a score for each outcome added.
At the beginning of the survey, participants will be presented with the information detailed in Additional file
Participants will be asked to score each of the outcomes listed using the Grading of Recommendations, Assessment, Development and Evaluations scale of 1 to 9. In the Delphi exercise the scale will be presented in the format 1 to 9, with 1to 3 labelled ‘not important’, 4 to 6 labelled ‘important but not critical’ and 7 to 9 labelled ‘critical’ [17 (link)]. Participants will be provided with an option to add additional outcomes that they think are relevant together with a score for each outcome added.
Outcomes will be listed alphabetically to avoid potential weighting of outcomes caused by the order in which they are displayed.
