Are freestanding midwifery units a safe alternative to obstetric units for low-risk primiparous childbirth? An analysis of effect differences by parity in a matched cohort study

摘要

BackgroundIntrapartum complications and the use of obstetric interventions are more common in primiparous childbirth than in multiparous childbirth, leading to concern about out of hospital birth for primiparous women. The purpose of this study was to determine whether the effect of birthplace on perinatal and maternal morbidity and the use of obstetric interventions differed by parity among low-risk women intending to give birth in a freestanding midwifery unit or in an obstetric unit in the North Denmark Region.
