Modified Bishop Score for Cervical Ripeness
Modified version of the Bishop score assessing cervical favourability for induction of labour. Scores dilation, effacement, station, consistency, and position. Score ≥8 = favourable cervix; score <6 = induction likely to require cervical ripening.
Score interpretation
Modified Bishop Score ≥8 — favourable cervix; induction likely to succeed
→ Proceed with induction of labour (ARM ± oxytocin); low risk of failed induction; discuss plan with patient
Modified Bishop Score 6–7 — borderline cervical favourability
→ Discuss options; may proceed with caution; consider ripening agent if ≥37 weeks and indication is firm; senior midwife/obstetrician involvement
Modified Bishop Score <6 — unfavourable cervix; cervical ripening recommended
→ Cervical ripening before induction: prostaglandin E2 (dinoprostone gel/pessary) or misoprostol; balloon catheter (mechanical ripening); reassess bishop score after 6–12 hours; inpatient monitoring required
