Comparative StudyDeclining invasive prenatal diagnostic procedures: A comparison of tertiary hospital and national data from 2012 to 2015.
In recent years, the superior accuracy of maternal plasma cell-free DNA-based prenatal screening has resulted in >50% national decline in amniocenteses and chorionic villus sampling (CVS), creating new implications for specialist training. ⋯ Our tertiary centre experienced a relatively smaller decline in prenatal diagnostic procedures compared with national figures, largely due to an increase in testing for ultrasound abnormalities. Our results demonstrate the increasing contribution of first trimester ultrasound in the detection of fetal abnormalities in the cell-free DNA era and the continued viability of specialist training in invasive procedures.

We discuss the potential risks of this practice and offer a harm minimisation approach to managing women requesting vaginal microbiome transfer after delivery by caesarean section.
