    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Modified Bishop Score for Vaginal Delivery and Induction of Labor

    Predicts likelihood of successful vaginal delivery with additional parameters to the original Bishop score.

    INSTRUCTIONS

    Replaces effacement with cervical length, increases weightedness of cervical dilation and adds additional modifiers as compared with the original Bishop Score.

    When to Use
    Pearls/Pitfalls
    Why Use

    Patients being evaluated for labor (including possible induction).

    • The Bishop Score 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 success and a score ≤6 suggests an unfavorable cervix.

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