About this study

Official title: Cost of Inpatient Care for Women Undergoing Outpatient vs. Inpatient Transcervical Balloon Cervical Ripening for Induction of Labor at Term

The objective of this study is to determine the impact of outpatient cervical ripening with transcervical balloon placement for induction of labor at term on the length and cost of inpatient hospitalization when compared to inpatient cervical ripening.

Read the detailed description

The objective of the study is to determine the impact of outpatient cervical ripening with transcervical balloon placement for induction of labor at term on the length and cost of inpatient hospitalization when compared to inpatient cervical ripening.

Specific Aims

In conducting this study, the investigators will accomplish the following specific aim:

To compare the length of inpatient care for women undergoing cervical ripening with a transcervical Foley placed in the outpatient vs. inpatient setting prior to induction of labor.

  • Primary outcomes of interest
  • The length of time (measured in minutes) spent on the inpatient unit (L\&D) from admission for cervical ripening and/or labor induction until delivery.

Outpatient arm:

Time for the participants in the outpatient group will be measured from the time the participant is admitted to the hospital for induction of labor until she delivers.

Inpatient arm:

Time for the participant in the inpatient group will be measured from the time the participant is admitted to the hospital for cervical ripening with balloon placement and induction until she delivers.

Time from admission to L\&D until delivery = total INPATIENT until delivery (hours)

  • Cost Analysis

Cost/charges will be calculated for the time spent in the outpatient and inpatient unit for both randomization groups.

Cost will be based on information obtained from Enterprise Analytics charges for the time each participant spends in outpatient care, inpatient care, hospitalized from admission to the L\&D unit to delivery.

The investigators will report on the delta/difference in average costs of outpatient and inpatient care between the outpatient and inpatient arms of the study.

Information will be obtained from the finance department at LVHN.

  • Secondary outcomes of interest to be compared by randomization groups include:
  • maternal outcomes
  • mode of delivery, chorioamnionitis, endometritis, placental abruption, urinary tract infection, preeclampsia, wound infection, venous thromboembolism, maternal treatment with postpartum antibiotics
  • neonatal outcomes
  • neonatal birthweight, Apgar scores, admission to the neonatal intensive care unit (ICU), neonatal ICU length of stay, neonatal hypoglycemia, neonatal sepsis, neonatal seizures, meconium aspiration, intubation for respiratory support, neonatal length of stay (total), umbilical cord gas pH, neonatal death or stillbirth
  • dosing of narcotic medications before regional anesthesia
  • total oxytocin infusion dosing
  • total length of stay for mothers and neonates

Questions about this trial

What is this clinical trial studying?

A study testing Outpatient Foley balloon placement and Inpatient Foley Balloon placement in people with Pregnancy Outcome, run by Lehigh Valley Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The length of time (measured in minutes) spent on the inpatient unit from admission from cervical ripening and/or labor induction until delivery. (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2025; AzTrials last refreshed its copy on 1 Nov 2026.
