Introduction:
In Norway, as in many other countries, vulnerable pregnant women may need additional care, involving interdisciplinary collaboration. This study was performed to describe how Norwegian community midwives experienced collaboration with other professionals in the care of vulnerable pregnant women.

Material and Methods:
A quantitative cross-sectional survey was distributed through both Norwegian midwives’ associations and on a Facebook-group for midwives in summer 2020. Community midwives were asked about their experience of collaboration. Associations between background factors and collaboration variables were assessed. Descriptive analyses using SPSS statistical software were performed.

Results:
Norwegian community midwives reported good collaboration with public health nurses, while experienced communication with GPs, child welfare-, drug welfare- and mental health-services as poor. Patient coordination meetings, regular meetings with collaborative partners and the Individual Care plans were not regularly used. Collaboration was enhanced by >10 years of experience and having completed a training program to identify and support vulnerable women called “Early start”.

Conclusions:
This study indicates that interdisciplinary training programmes for professionals involved in the care of vulnerable pregnant women can improve collaboration.
