For a short explanation of why the committee made these recommendations and how they might affect practice, see the rationale and impact section on induction of labour for intrauterine fetal death after previous caesarean birth. The Bishop scoring system utilizes cervical dilation, position, effacement (thinning), consistency of the cervix, and fetal station. A failed attempt at induction may mean that you will need to try another induction or have a cesarean delivery. It is checked prior to induction, and during induction to assess progress (6 hours post-table/gel, 24 hours post-pessary): [2021].
