BackgroundUltrasound training is a vital component of maternal-fetal medicine fellowships in the United States. Of the 18 months of core clinical training, the American Board of Obstetrics and Gynecology currently requires a minimum of 3 months to be dedicated to ultrasound to be eligible for board certification. However, the experience and degree of hands-on training differ among the fellowship programs and have not been reassessed for nearly a decade.ObjectiveTo assess regional heterogeneity in the ultrasound training experience during maternal-fetal medicine fellowship in the United States.Study designA survey was distributed to postgraduate year (PGY)-6 maternal-fetal medicine fellows registered to attend an annual ultrasound training course before the conference (n=114). For programs with >1 fellow attending (n=39), only 1 of them completed the survey to represent the program. The questions included demographics of the program, ultrasound training structure, the fellows' self-perception of ultrasound capabilities, research, mentorship, and technical aspects of sonography.ResultsSeventy two postgraduate year 6 fellows with a wide geographic distribution as follows completed the survey (96% response rate): 10 (14%) from the West, 16 (22%) from the Midwest, 17 (24%) from the South, and 29 (40%) from the Northeast. Respondents undergoing training in the South were less likely to report feeling comfortable performing nuchal translucency and detailed anatomic surveys than those from other regions (nuchal translucency: P=.046; anatomy: P=.011). Most of the respondents reported feeling comfortable performing growth (78%) and umbilical artery Doppler (58%) and feeling uncomfortable with three-dimensional ultrasound, neurosonography, and fetal echocardiography. Respondents in the Northeast were more likely to report feeling comfortable performing chorionic villus sampling (P=.001). There was no difference among fellowship programs in the presence or absence of ultrasound curriculum, bedside teaching, ultrasound-focused research mentorship, or months of ultrasound training.ConclusionDespite the standardization of ultrasound training structure across the United States, there remains regional heterogeneity in fellow self-reported comfort with specific ultrasound techniques and chorionic villus sampling at a midpoint in their fellowship training. The maternal-fetal medicine attending involvement at the bedside did not affect the fellow self-reported comfort with ultrasound surveys. This study highlights the need for further optimization of maternal-fetal medicine fellowship ultrasound training, especially in advanced sonography and diagnostic procedures.
