A study that has the potential to change our understanding of risk of VBAC was published earlier this year, just as many countries were entering lockdown. As a result this study may have gone "under the radar" despite its importance.
The OptiBIRTH trial was conducted in three EU countries and in a sample of just under 2000 women separated in control and intervention groups (e.g. birthing at hospitals participating in a VBAC intervention-study and hospitals not participating), only two uterine ruptures occurred, one in each group (meaning there was no difference between the two groups), with an incidence rate of 1:1000.
This is a small study that suggests that uterine rupture during VBAC may be rarer than originally thought, and confirms the argument that not offering women information about VBAC breaches her human right to bodily autonomy.
Babies in both groups were equally healthy (non-significant differences in adverse outcomes between groups). It will be interesting to see the effects of this trial on further VBAC research (e.g. larger studies) and practice over time.
