This study aims to describe changes over time about the mode of birth and perinatal outcomes in second-pregnancy women with one previous cesarean birth in the Netherlands over the past 20 years.MethodsWe conducted a nationwide, population-based study using the Dutch perinatal registry. The mode of birth (intended vaginal birth after cesarean (VBAC) compared with planned cesarean birth) was assessed in all women with one previous cesarean birth and no prior vaginal birth who gave birth to a term singleton in cephalic presentation between 2000 and 2019 in the Netherlands (n = 143,146). The reported outcomes include the trend of intended VBAC, VBAC success rate, and adverse perinatal outcomes (perinatal mortality up to 7 days, low Apgar score at 5 min, asphyxia, and neonatal intensive care unit admission >= 24 h).ResultsIntended VBAC decreased by 21.5% in women with one previous cesarean birth and no prior vaginal birth, from 77.2% in 2000 to 55.7% in 2019, with a marked deceleration from 2009 onwards. The VBAC success rate dropped gradually, from 71.0% to 65.3%, across the same time period. Overall, the cesarean birth rate (planned and unplanned) increased from 45.2% to 63.6%. Adverse perinatal outcomes were higher in women intending VBAC compared with those planning a cesarean birth. Perinatal mortality initially decreased but remained stable from 2009 onwards, with only minimal differences between both modes of birth.ConclusionsIn the Netherlands, the proportion of women intending VBAC after one previous cesarean birth and no prior vaginal birth has decreased markedly. Particularly from 2009 onwards, this decrease was not accompanied by a synchronous reduction in perinatal mortality.Intended vaginal birth after cesarean (VBAC) rates in percentages, with an inset displaying perinatal asphyxia and perinatal mortality rates up to 7 days postpartum in permilles. aThe Netherlands 2000 to 2019.image Show less
