Induction is often considered at a Bishop Score of ≤5.
Addition of the selected points.
Facts & Figures
- Scores ≤ 5 suggest an unfavorable cervix, and that induction may be necessary for successful vaginal delivery.
- Scores 6-7 do not definitively predict whether or not induction will be successful. Consider induction or augmentation of labor based on clinical judgment.
- Scores ≥ 8 suggest spontaneous vaginal delivery is more likely and augmentation or induction may be unnecessary.
