Put on the sidelines of palliative care: a qualitative study of important barriers to GPs' participation in palliative care and guideline implementation in Norway.

Significant structural and individual barriers to GPs' participation in palliative care exist, which hamper the implementation of the guideline. GPs should be involved as stakeholders when guidelines involving them are created. Introduction of new professionals in primary care needs to be actively managed to avoid inappropriate collaborative practices. Continuity of the GP-patient relationship must be maintained throughout severe illness and at end-of-life.
