This retrospective cohort study aims to determine the effect of cervical preparation with osmotic dilators plus adjuvant overnight mifepristone compared to same-day misoprostol prior to dilation and evacuation between 18 0/7 and 21 6/7 weeks’ gestation on procedure time and other important clinical outcomes. Our sample size (n=574) will also allow greater numbers to describe important but uncommon secondary outcomes including acute complications to better contextualize the implications of these two cervical preparation strategies in practice.
