Ripening Approaches for Prompt Induction and Delivery (RAPID-DS) Study

This study is looking at the best way to prepare the cervix (the lower part of the uterus) for labor induction in women who are pregnant for the first time. It compares two methods: one where Dilapan-S (a device that helps open the cervix) is placed 12-24 hours before you come to the hospital, and another where Dilapan-S is placed at the hospital along with misoprostol (a medication that helps ripen the cervix). The study wants to see which approach helps achieve a vaginal delivery within 24 hours of being admitted to the hospital. You might be able to join if you are at least 18 years old, pregnant with one baby, and planning to have your labor induced. The study is currently recruiting 260 participants.

Study design
This is an interventional study comparing two different methods for cervical ripening. It plans to enroll 260 participants.
What's involved
You would either have Dilapan-S placed in an outpatient setting 12-24 hours before hospital admission, or have Dilapan-S placed and receive misoprostol at the hospital.
Compensation
Not stated in the trial record.
Follow-up
The primary outcome is measured within 24 hours of hospital admission.
