title: Cervical length compared to Bishop's score for prediction of pre-term birth in women with pre-term labour.
abstract: Cervical length (by transvaginal sonography) was compared to Bishop's score (by digital examination of cervix) for prediction of pre-term birth in women with pre-term labour. The study group was 100 women with a singleton pregnancy with pre-term labour between 26-36 weeks' gestation. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of cervical length ≤2.5 cm ( by TVS) to predict delivery within 48 h and 7 days of admission were 62.5%, 89.5%, 65.2%, 88.3%, and, 60.0%, 96.9%, 91.3%, 81.8%, respectively. Similar values of Bishop's score ≥5 were 62.5%, 85.52%, 57.69%, 87.83%, and, 62.8%, 93.8%, 84.6%, 82.4%, respectively. To conclude, both Bishop's score ≥5 and reduced cervical length of ≤2.5 cm (by TVS) can predict the risk of pre-term delivery within 48 h or 7 days.
