What we have all known, all along. The ARRIVE trial needs to be exposed for its faults and binned. Please never let me hear you quoting it.
A new study has reinforced our knowledge that, in real world settings, healthy women are more likely to end up having a caesarean if they have induction of labour than if they go into labour on their own.
⭐️
The study will be published in the European Journal of Obstetrics & Gynecology and Reproductive Biology.

The authors conclude that, “Awaiting the natural onset of labor, if there are no maternal or fetal reasons to intervene, may yield no worse a perinatal outcome than an earlier induction of labor. The consequences of a cesarean delivery are known to be associated with immediate and longer-term maternal morbidity, and this may be potentially avoided, if elective inductions of labor can be minimized.” (Levine et al 2021).

This result, which echoes that of a number of similar studies, is in contrast to the findings of the often cited ARRIVE trial.
⭐️
So why is that?
⭐️
One reason is that the participants in the ARRIVE trial were not representative of all women. Another is that women in the ARRIVE trial had very medicalised care. And, as Levine et al (2021) note, there’s a difference between what happens in the setting of a trial, and in the real world. I’ve written lots on this, so here are some resources if you’d like to know more.
