Inpatient Versus Outpatient Foley Cervical Ripening Study

The aim of the current study is to compare the efficacy and safety of cervical ripening with
transcervical Foley catheter in inpatient vs outpatient setting in a diverse, urban
population within the United States. We hypothesize that there will be no differences in
time-to-delivery, failed induction rates, cesarean section rates, or maternal/neonatal
morbidity and that there will be no differences in total length of stay (LOS), hours of
sleep, active labor duration, and perceived satisfaction between groups.

Inclusion Criteria:

- Indication for Induction of Labor is present

- Gestational age > 37 completed weeks with absence of comorbidities with an optimal
dating (ultrasonography was performed before 22 weeks gestation)

- Singleton fetus in cephalic presentation confirmed with an ultrasound at the time of
presentation for induction of labor

- Cervical exam with Bishop Score <6

- Intact membranes

- Normal vital signs (blood pressure < 140/90, normal body temperature) at the time of
presentation for Induction of Labor and within the last 24 hours

- Maternal age ≥18 years of age

the time in the past week)

- Poorly controlled chronic hypertension, gestational hypertension or preeclampsia
(patient requiring IV antihypertensives within 4 hours of arrival)

- Vaginal bleeding

- Any conditions that require continuous electronic fetal monitoring either by
institutional policy or provider determination (intrahepatic cholestasis of pregnancy,
