ABSTRACT
OBJECTIVE: To compare the ability of six scoring systems to predict successful labor induction with cervical ripening among women with a Bishop score less than 3.
METHODS: Secondary analysis of data from a prospective, multicenter observational Methods of Induction of Labor and Perinatal Outcomes (MEDIP) cohort study in 94 obstetrical French units. We included women with a Bishop score less than 3 before cervical ripening. We compared six scores: Bishop, simplified Bishop, modified Bishop, simplified Bishop including parity, Hughey, and Levine scores. Vaginal delivery defined successful labor induction. The ability of each score to predict successful labor induction was evaluated by comparing their area under the curve (AUC).
RESULTS: Among the 600 eligible women in this study, 408 (68%) delivered vaginally. Body mass index (24.7 ± 5.5 kg/m2 vs. 26.0 ± 5.7 kg/m2 ; P = 0.01) and nulliparity (48.8% vs. 85.4%; P < 0.0001) were lower in the successful induction group, whereas height was higher (165.3 ± 6.0 cm vs. 163.7 ± 6.0 cm; P = 0.002). The simplified Bishop including parity, Hughey, and Levine scores had the highest AUC (0.70 [0.65-0.73], 0.68 [0.64-0.74], and 0.69 [0.65-0.74], respectively).
CONCLUSION: In women with a very unfavorable cervix, scores that include parity predict successful labor induction more accurately, such as simplified Bishop including parity, Hughey, or Levine scores.
