1 Scope and Purpose of the Guideline
1.1 Statement of problem
The mean duration of a normal pregnancy, calculated from the 1st day of the last menstrual period, is 280 days or 40 + 0 weeks of gestation (GW). A pregnancy prolonged by more than 14 days, in other words, a pregnancy lasting 294 days or 42 + 0 GW or more, is defined by the WHO and FIGO as prolonged, post-term or post-mature pregnancy. The period between 40 + 0 and 41 + 6 GW is referred to as late-term pregnancy.
More than 40 % of all pregnant women give birth after the expected date of delivery. Management of pregnant women with no onset of labor ranges from expectant management consisting only of intensive monitoring of mother and child to induction of labor.
1.2 Patient target population
This guideline focuses on the large group of women with low-risk singleton pregnancies who have no specific pregnancy risks (e.g. gestational diabetes, preeclampsia or IUGR).
1.3 Target users and area of care
This guideline aims to provide evidence-based recommendations to both gynecologists in private practice and physicians working in maternity hospitals to assist in decision-making when advising and managing pregnant women who are past their estimated and verified due date. This guideline differentiates between late-term pregnancy (40 + 0 GW to 41 + 6 GW) and post-term pregnancy (from 42 + 0 GW).
