Research questions that reached consensus at the end of the Delphi process

Prioritised unanswered questions about MLTC (multimorbidity) in primary care for the academic research community over the next 5–10 years	Delphi consensus round	% endorsing (% rejecting)	Type of question
1. What skill mix and training are needed for the primary care workforce to manage MLTC?	2	71% (8%)	Models of care
2. Which aspects of the current primary care model need to be adapted to improve management of MLTC?	1	74% (7%)	Models of care
3. How can we best develop care pathways for people with MLTC that are patient-centred and reduce burden of treatment?	1	81% (0%)	Models of care
4. How can primary care interventions contribute to prevention of disease onset or decline in function or quality of life?	2	79% (8%)	Models of care
5. How can primary care better interact with the wider health and social care system to improve MLTC care?	1	78% (4%)	Models of care
6. What are the barriers to implementation of potentially effective interventions?	1	89% (4%)	Models of care
7. How should MLTC be incorporated into primary care resource allocation models to better reflect the complexity of care and provide adequate resources?	1	78% (4%)	Methods and data
8. How can we improve the quality of data we gather from primary care for a better understanding of MLTC (e.g., disease severity, social factors, biological measures)?	1	74% (19%)	Methods and data
9. How can we make better use of administrative data and quasi-experimental observational studies to improve evaluation of MLTC interventions?	2	71% (8%)	Methods and data
10. What are the best ways of measuring wellbeing and quality of life for trials of MLTC interventions in primary care?	1	70% (7%)	Methods and data
