To assess neonatal and maternal morbidity in twins ≥ 32 weeks' gestation, related to the changes in planned mode of delivery, a retrospective cohort study was performed, including 185 twin births delivered in the Atrium Medical Centre, Heerlen, during the years 2003-2008. The results were compared with those of an earlier study from our department during the period 1999-2002. Compared with the 1999-2002 cohort, the elective caesarean section rate significantly increased from 17.7% to 36.8%. The secondary caesarean rate significantly decreased from 15.9% to 8.8%, but increased from 1.2% to 3.3% for only twin B. No significant differences in serious neonatal morbidity rates for twins A and B were found between both study periods, neither in the elective caesarean group, nor in the planned vaginal birth group. Serious maternal morbidity was not significantly increased in both groups compared with the 1999-2002 cohort.
