Abstract

Objective: The objective of the present study is to investigate trends in birth asphyxia and perinatal mortality in the Netherlands over the last decade. Methods: A nationwide cohort study among women with a term singleton pregnancy. We assessed trends in birth asphyxia in relation to obstetric interventions for fetal distress. Birth asphyxia was defined as a 5-minute Apgar score <7 (any asphyxia) or 5-minute Apgar score <4 (severe asphyxia). Perinatal mortality was defined as mortality during delivery or within 7 days after birth. Multivariable analyses were used to adjust for confounding factors. Results: The prevalence of birth asphyxia was 0.85% and severe asphyxia 0.16%. Between 1999 and 2010 birth asphyxia decreased significantly with approximately 6% (p = 0.03) and severe asphyxia with 11% (p = 0.03). There was no significant change in perinatal mortality rate (0.98 per 1000 live births). Simultaneously the referral rate from primary to secondary care during labor increased from 20% to 24% (p < 0.0001) and the intervention rate for fetal distress from 5.9% to 7.7% (p < 0.0001). Conclusion: In the Netherlands, the risk of birth asphyxia among term singletons has slightly decreased over the last decade; without a significant change in perinatal mortality.
