N1 - Funding Information: We would like to thank all perinatal healthcare professionals who made it possible for us to evaluate these perinatal registry and audit data: midwives, obstetricians, pediatricians/neonatologists, nurses, pathologists and others who participated in the audits. The perinatal audit as well as the perinatal registry is funded by The Ministry of Health (VWS). Publisher Copyright: © 2019 Nordic Federation of Societies of Obstetrics and Gynecology (NFOG).

N2 - Introduction: Midwife-led models of care have been the subject of debate for many years. We conducted a study to compare intrapartum and neonatal mortality rates in midwife-led (primary) vs obstetrician-led (secondary) care at the onset of labor in low-risk term women. Material and methods: We performed an unmatched and a propensity score matched cohort study using data from the national perinatal audit registry (PAN) and from the national perinatal registry (PERINED) of the Netherlands. We included women with singleton pregnancies (without congenital anomalies or antepartum fetal death) who gave birth at term between 2010 and 2012. We excluded the following major risk factors: non-vertex position of the fetus, previous cesarean birth, hypertension, diabetes mellitus, prolonged rupture of membranes (≥24 hours), vaginal bleeding in the second half of pregnancy, nonspontaneous start of labor and post-term pregnancy (≥42 weeks). The primary outcome was intrapartum or neonatal mortality up to 28 days after birth. Secondary outcome measures were mode of delivery and a 5-minute Apgar score <7. Results: We included 259 211 women. There were 100/206 642 (0.48‰) intrapartum and neonatal deaths in the midwife group and 23/52 569 (0.44‰) in the obstetrician group (odds ratio [OR] 1.11, 95% CI 0.70-1.74). Propensity score matched analysis showed mortality rates of 0.49‰ (26/52 569) among women in midwife-led care and 0.44‰ (23/52 569) for women in obstetrician-led care (OR 1.13, 95% CI 0.65-1.98). In the midwife group there were significantly lower rates of vaginal instrumental deliveries (8.4% vs 13.0%; matched OR 0.65, 95% CI 0.62-0.67) and intrapartum cesarean sections (2.6% vs 8.2%; matched OR 0.32, 95% CI 0.30-0.34), and fewer neonates with low Apgar scores (<7 after 5 minutes) (0.69% vs 1.11%; matched OR 0.61, 95% CI 0.53-0.69). Conclusions: Among low-risk term women, there were comparable intrapartum and neonatal mortality rates for women starting labor in midwife-led vs obstetrician-led care, with lower intervention rates and fewer low Apgar scores in the midwife group.
