Literature in the field of nursing was searched on PubMed and CINAHL, and empirical qualitative studies from outpatient and inpatient care in seven countries were included. The studies were appraised according to national guidelines and templates and were analysed and synthesised according to the meta-ethnographic approach.

The analysis revealed four themes: (i) a threat to professional boundaries, (ii) a resource for the team, (iii) the quest for autonomy and control, and (iv) necessary properties of a developing interprofessional collaboration. Based on these themes, the synthesis was created and presented as a metaphorical journey.
