However, there is uncertainty on the policy concerning the timing of induction for post-term
pregnancy or impending post-term pregnancy, leading to practice variation between caregivers. Previous studies on
induction at or beyond 41 weeks versus expectant management showed different results on perinatal outcome though
conclusions in meta-analyses show a preference for induction at 41 weeks. However, interpretation of the results is
hampered by the limited sample size of most trials and the heterogeneity in design. Most control groups had a policy
of awaiting spontaneous onset of labour that went far beyond 42 weeks, which does not reflect usual care in The
Netherlands where induction of labour at 42 weeks is the regular policy. Thus leaving the question unanswered if
induction at 41 weeks results in better perinatal outcomes than expectant management until 42 weeks.
