    Pearls/Pitfalls
    Why Use

    Patients being evaluated for labor (including possible induction).

    • The Bishop Score for Vaginal Delivery and Induction of Pregnancy was originally developed to predict failure of elective induction in multiparous women.
    • It is commonly considered for predicting the need for caesarean section after induction and preterm labor.
    • Some centers recommend using the Modified Bishop Score which was developed in 1982 as an update to Bishop's original 1964 scoring system.
    • The scoring system was developed prior to cervical ripening agents.
    • Typically a score ≥ 8 is used to predict spontaneous vaginal delivery without induction and a score ≤5 suggests an unfavorable cervix likely to require induction.

    Predicting which women will successfully deliver with induction is difficult, and the Bishop Score is a standardized system used for evaluation.
