Abstract
Objective: To evaluate the incidence of implementation of universal cervical length (CL) screening for preterm birth (PTB) prevention among institutions with Maternal–Fetal Medicine (MFM) fellowship training in the United states.
Methods: In January 2015, we conducted a national survey of institutions with MFM Fellowship Programs regarding implementation of universal CL screening, defined as CL screening of women with singleton gestations without a prior spontaneous PTB. We identified whether a transabdominal ultrasound (TAU) or transvaginal ultrasound (TVU) was used for screening. Results were compared by geographical regions.
Results: We identified 78 MFM fellowship programs nationwide, of which 100% responded to the survey, provided by MFM fellows (86%) and MFM division directors (14%). In January 2015, 53 programs (68%) had implemented a CL screening program, with 25 programs (32%) using TVU while the rest (36%) used TAU for CL screening. The 16 programs in the Midwest had the highest percent of CL screening (15 programs, 94%), with the highest use of TVU (8 programs 50%). The 24 programs in the South had the lowest percent of CL screening (14 programs, 58%) (odds ratio [OR]: 0.52, 95% confidence interval [CI]: 0.19–1.46) and the lowest use of TVU (3 programs,12.5%) (OR: 0.22, 95% CI: 0.05–0.78) compared to rest of US).
Conclusion: Universal CL screening has been implemented by over two-thirds of institutions with MFM Fellowship Programs, as of January 2015. Of these programs, about half screen by TAU and half by TVU.
