Structured process for workshop group work.

Step	Process
Written responses	Participants wrote individual answers to ‘prompt questions’ in response booklets (see the Online Supplementary Figure S1). These were tailored to the critical question each group was focusing on, for example, ‘What are the core components of a holistic breathlessness service?’ (group 1); ‘Where should a holistic breathlessness service be based?’ (group 2); and ‘What is the ideal set of outcomes to measure for patients?’ (group 3).
Initial reflections	Reflections from this exercise in relation to the critical question were then discussed.
Individual recommendations	Participants wrote their individual recommendations in their response booklets, with a rationale and indication of appropriateness for clinical practice, policy and/or research.
Ranking	Participants were asked to rank each of their recommendations from highest to lowest.
Discussion	Participants in turn read out their highest ranked recommendation and rationale, which were discussed by the group. This continued until individual lists were exhausted or time was exceeded (approximately 25 minutes).19
