Cervical Ripening
Brief summary
Induction of labor is a frequently planned obstetric procedure. Induction for women with an unfavorable cervix (bishop score \<6) increases the risk of cesarean section. This risk may be reduced by ripening or softening the cervix before the induction of labor. This protocol outlines a randomized trial of 200 women evaluating the placement and use of Cervidil to the post vaginal fornix to soften the cervix in preparation for induction. This trial is looking at inpatient vs outpatient pre-induction cervical ripening using Cervidil and the effects on (1) maternal and newborn outcomes including time of admission to delivery, (2) system healthcare cost, (3) cost to patient, and (4) patient satisfaction. The investigators hypothesize when compared to patients admitted to the hospital for cervical ripening: 1. From the time of admission, patients in the outpatient cervical ripening arm will progress to complete cervical dilation in less time. 2. The total overall cost of care for the encounter will be reduced for the group in the outpatient cervical ripening arm. 3. Patients in the outpatient cervical ripening arm will have more overall satisfaction.
Interventions
Dinoprostone (10 mg) is a vaginal insert approved to start and/or continue the ripening of the cervix in pregnant women who are at or near the time of delivery and in whom there is a medical reason for inducing (bringing on) labor. Women randomized to the outpatient cervical ripening group will be administered the drug prior to their induction and discharged after monitoring and physician approval. They will return for their schedule induction.

| Outpatient Cervical Ripening Patients randomized to the outpatient cervical ripening arm will come in for a scheduled visit in Labor and Delivery prior to her scheduled induction. A research nurse will examine her and place the Cervidil insert into the posterior vaginal fornix. The patient will be monitored for 2 hours and sent home after a the following are present: (1) reactive non-stress test (NST) (2) category 1 tracing x 2 hours (3) no vaginal bleeding (4) normal maternal vital signes (5) intact bag of water (BOW) and (6) less than 1 contraction every 10 minutes at the time of discharge. The patient will remove the insert the following morning prior to her scheduled induction.

| Inpatient Cervical Ripening The patient will be admitted into the Labor and Delivery unit prior to her scheduled induction. A research nurse will examine her and place the Cervidil insert into the posterior vaginal fornix. The patient will be watched with continuous fetal monitoring for 2 hours. The patient remains hospitalized and the following morning the induction will be started per Intermountain Healthcare protocol.
