Methods: We conducted a prospective cohort study of 726 consecutive non-laboring, term pregnant women presenting to University-based antenatal testing unit between 1 July 2001 and 31 March 2002. Subjects underwent a TVUS for cervical length followed by a digital cervical examination by a physician blinded to the results of the ultrasound. Linear regression analysis was used to correlate the findings of cervical length by ultrasound with cervical dilatation and effacement by digital examination. Results: In 726 women, the relationship between TVUS cervical length and cervical dilatation and effacement measured digitally were found to be significantly related (p<0.001), but weak, with a 15 and 23% goodness of fit, respectively, based on the linear model. Using multivariate logistic and linear regression, respectively, TVUS cervical length predicted mode of delivery but did not predict time to spontaneous labor. Digital measurement of cervical dilatation was predictive of time to spontaneous labor. Conclusions: There is a statistically significant correlation between TVUS measurement of cervical length and digital cervical exam though the correlation is weak. TVUS measurement of cervical length was predictive of mode of delivery while controlling for digital cervical examination, parity and time to spontaneous labor. Digital cervical dilatation was predictive of time to spontaneous delivery.
