Preterm birth is a leading cause of neonatal morbidity and mortality worldwide; evidence-based strategies to decrease preterm birth are desperately needed. The purpose of this study was to estimate which of three strategies for screening for shortened cervix in asymptomatic low-risk women is the most cost-effective in terms of prevention of preterm birth and associated morbidity. A decision analysis model was developed from available published evidence comparing three strategies in screening asymptomatic low-risk women for shortened cervix: (1) cervicometer with subsequent referral for transvaginal ultrasound, (2) transvaginal ultrasound screening, and (3) no screening.

Background: Preterm birth remains a major cause of neonatal morbidity and mortality worldwide. Short cervical length (CL) as measured by transvaginal ultrasound (TVU) in the second trimester represents the single most predictive risk factor for spontaneous preterm birth. Previous studies have addressed, in part, the limitations of TVU availability by utilizing a cervicometer to screen patients for short cervix, identifying those patients who may not benefit from TVU CL screening.

Aim: The ultrasound measurement of the cervix is the gold standard for assessing the risk of preterm delivery. We compared the accuracy of this technique with measurements obtained by the cervicometer Cervilenz®. The purpose was to show that this device can be used as a screening tool, low cost, in the diagnosis of preterm labor.

We measured the effect of a progesterone antagonist on the pregnant cervix with a custom-built cervicometer. The change in cervical diameter was studied in 11 pregnant patients after oral administration of 600 mg of RU-486. In all cases RU-486 ripened the cervix (p = 0.
