Universal Cervical Length Screening

A look at implementation and outcomes

Universal cervical length screening was implemented successfully with 85% of participants in a cohort study of 10,871 women who underwent transvaginal cervical length screening at a single institution. Institutional protocol recommended transvaginal cervical length measurement at the time of the anatomic survey between 17 to 23 weeks in all women with singleton, viable pregnancies, without current or planned cerclage. Researchers found:

• Rates of early, but not late, spontaneous preterm birth were significantly higher among women who did not undergo cervical length screening (aOR=2.01).

• Overall incidence of short cervix was low and women with significant risk factors for preterm birth were more likely to decline screening.

• Patients who declined cervical length screening were more likely to be African American (aOR=2.17), obese (aOR=1.18), multiparous (aOR=1.45), younger than 35 years (aOR=1.24), or smokers (aOR=1.42).
