The goal of this randomized control trial is to compare outpatient transcervical foley balloon to inpatient vaginal misoprostol in pregnant women for cervical ripening. The main questions it aims to answer are:
Participants will be randomized to either the outpatient transcervical foley balloon group or to the inpatient intravaginal misoprostol group. The researchers will compare if outpatient transcervical foley balloon decreases the tie from hospital admission to delivery of the baby.
This is a prospective randomized unblinded control trial. Consented patients will have a cervical exam performed in the clinic to confirm that the bishop score is less than 6. Once this and the inclusion criteria are met, the participant will be randomized to either the outpatient transcervical foley arm or the vaginal misoprostol arm. Each pregnant woman will undergo the intervention stated in the numbered envelope which will be distributed based on their order of inclusion in the study. Due to the nature of the procedure, blinding could not be done.
Participants randomized to the transcervical foley group will be scheduled an appointment in the clinic the day before their scheduled induction day for the final screen and foley placement. On the other hand, participants randomized to the vaginal misoprostol group will be admitted to the labor and delivery unit on the day of their scheduled induction. All participants will undergo a cervical examination before the assigned intervention to verify their eligibility status. Those who do not meet the eligibility criteria, will be excluded. Both transcervical foley and vaginal misoprostol are standard of care for induction of labor at Hurley Medical Center. Thus, there would be no additional cost to the patient. The only difference in the study is the setting in which the transcervical foley is placed, i.e. in the obstetrics clinic as an outpatient.
Oxytocin will be initiated in all patients who did not have at least three regular contractions in 10 minutes. Continuous fetal heart rate monitoring and uterine activity monitoring will be performed in all patients. Amniotomy will be performed during the course of labor at the discretion of the health care provider and epidural anesthesia will be administered per the patient's request.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Inpatient Vaginal Misoprostol | Active Comparator | These participants will receive intravaginal Misoprostol in the inpatient setting per our standard hospital protocol for cervical ripening. |
|
| Outpatient transcervical foley balloon | Experimental | These participants will receive a catheter which will be placed by a physician present in the clinic, however, patient are discharged home for 12 hours until their time of induction of labor. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Outpatient transcervical foley balloon | Procedure | These participants will receive a 16-French Foley catheter which will be placed by a physician present in the clinic. The balloon will be inflated with 40 mL of sterile water, and the catheter will then be gently withdrawn so that the balloon applies pressure against the internal os. The catheter will then be taped to the inner thigh. |
| Measure | Description | Time Frame |
|---|---|---|
| Time from hospital admission to delivery of the newborn | The primary outcome is to determine if there is a difference in the time from admission to delivery for those who receive transcervical foley balloon in the clinic the day before induction compared to those who get vaginal misoprostol in the hospital on the day of the induction | From hospital admission until delivery of the newborn |
| Measure | Description | Time Frame |
|---|---|---|
| Chorioamnionitis/endometritis | Number of participants with fever, increased white blood cell count or foul smelling discharge in the outpatient transcervical foley group compared to that of in the intravaginal Misoprostol group | From hospital admission until 2 weeks postpartum |
| Cesarean delivery |
