Brief Summary
A multicenter pragmatic randomized trial of nulliparous women undergoing a term (≥37 weeks) induction of labor wherein the provider intends to use a Foley catheter for cervical ripening. The investigators will be comparing outpatient cervical ripening with a Foley catheter to routine inpatient cervical ripening (Foley +/- other method). With this trial, the investigators aim to test our central hypothesis that outpatient Foley will decrease the primary Cesarean Delivery (CD) rate and risk of maternal/neonatal morbidity compared with inpatient cervical ripening.

Outcome Measures
Primary Outcomes (1)
Incidence of Cesarean Delivery
Incidence of cesarean delivery in women randomized to outpatient cervical ripening with the Foley catheter compared to women undergoing routine inpatient cervical ripening
At delivery
Secondary Outcomes (10)
Maternal morbidity incidence
Within 6 weeks of delivery
Maternal patient satisfaction as measured by the Hollins Martin Birth Satisfaction scale-Revised (BSS-R)
From time of delivery to discharge from hospital, up to 6 weeks from delivery
Neonatal morbidity incidence
Within 6 weeks of delivery
Maternal patient perception of control
From time of delivery to discharge from hospital, up to 6 weeks from delivery
Maternal overall length of stay
From date of delivery to date of discharge from hospital postpartum, up to 6 weeks from delivery
- +5 more secondary outcomes
Other Outcomes (1)
Heterogeneity of Treatment Effect/prespecified sub-groups
within 6 weeks of delivery
Study Arms (2)
Outpatient cervical ripening with Foley
EXPERIMENTALCervical ripening will begin with a Foley balloon in the outpatient setting
Standard of care Inpatient cervical ripening
NO INTERVENTIONCervical ripening will begin in the inpatient setting with Foley ballooon or other cervical ripening agent
Interventions
