Influencing factors in midwives' decision-making during childbirth: A qualitative study in the Netherlands.

Background: Dutch maternity care is based on the principle that pregnancy and childbirth are physiological processes. However, the last decade an increase of intra-partum referrals to obstetric-led care has been observed. Most of these referrals are among nulliparous women, non-urgent and occur during the first stage of labour.
