Outpatient cervical ripening using a Foley catheter

Official title: Cervical Ripening as an Outpatient Method Using the Foley: a Randomized Trial

Run by University of Pennsylvania · NCT05759988 · Data updated 2026-11-12

This study is testing if using a Foley catheter at home to help prepare the cervix for labor can reduce the need for C-sections and improve safety for first-time moms and their babies.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are nulliparous women aged 18 and older, with a live singleton pregnancy at term, who meet specific medical criteria for outpatient cervical ripening.

Probably not a fit

Patients with certain complications such as oligohydramnios, severe polyhydramnios, or other significant maternal or fetal health concerns may not benefit from this study.

What this trial studies

This multicenter pragmatic randomized trial focuses on nulliparous women who are eligible for induction of labor at term. It compares the effectiveness of outpatient cervical ripening using a Foley catheter against the traditional inpatient method. The primary goal is to determine if outpatient use of the Foley catheter can reduce the rate of Cesarean deliveries and lower maternal and neonatal morbidity. Participants will be monitored closely to ensure safety and efficacy throughout the process.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more efficient labor induction for women, reducing the need for Cesarean deliveries.

How similar studies have gone: Other studies have shown promising results with outpatient cervical ripening methods, suggesting potential for success in this approach.

Inclusion Criteria

* Eligible for induction of labor
* Live singleton gestation ≥37 weeks and \<42 weeks

* Intact membranes
* Bishop score ≤8 and cervical dilation \<3 cm
* English or Spanish speaking (Able to read/understand consent and instructions)
* Have reliable transportation to get back to the hospital and have a self-reported safe residence to go home to with the Foley catheter

Exclusion Criteria

* Known oligohydramnios (DVP \<2cm)
* Known moderate-severe polyhydramnios (AFI ≥30 at time of delivery)
* Concern regarding fetal status during antenatal testing: At provider discretion, but includes fetal decelerations, biophysical profile ≤6/10
