Abstract Objective To examine the value of combining cervical length and maternal characteristics in a prolonged‐pregnancy clinic prediction probability firstly, spontaneous onset labor within subsequent 10 days secondly, need for Cesarean section. Methods This was prospective study women with singleton pregnancies attending an ultrasound‐based at 40 + 4 to 41 6 weeks gestation. The policy delay induction by 7–10 unless there evidence specific medical or obstetric indication mother wanted earlier delivery. measurement not given obstetrician, midwife patient. Regression analysis used determine which following factors had significant contribution predicting labor: age, body mass index (BMI), ethnic origin, parity length. also amongst characteristics, provided Results We examined 2316 but we excluded from further 452 (19.5%) cases because iatrogenic delivery carried out days, including 427 (340 request 87 indications) 25 In remaining 1864 1536 (82.4%) 328 (17.6%). rate section 15.2% (233 1536) those 36.0% (118 328) whose induced. demonstrated that were contributions length, BMI, gestational labor, ethnicity.
