When to get consent for a possible cesarean during labor

The Optimize Trial: Optimizing Timing of Cesarean Delivery Consent on Labor and Delivery

Not applicable Interventional Duke University · NCT07117708

This trial tests whether asking patients to sign consent for a possible cesarean when they are admitted to Labor and Delivery, versus only consenting if it becomes clinically likely, improves the childbirth experience for people who plan a vaginal birth but later need an unplanned cesarean.

What this trial studies

This is a randomized controlled trial enrolling patients scheduled for induction of labor who receive prenatal care at Duke Perinatal Durham or Duke Women's Health Associates. Participants are consented for the research between 34 and 41 weeks and randomized to either sign surgical consent for a possible cesarean on admission to Labor and Delivery or to be consented only if cesarean appears clinically indicated (current standard). On postpartum day 1 participants will receive a text link to a survey about their surgical consent experience and overall childbirth experience. The study will compare reported negative delivery experiences and measures of preparedness and education between the two groups.

Who should consider this trial

Good fit: Adults 18 years or older who receive prenatal care at Duke Perinatal Durham or Duke Women's Health Associates, are between 34+0 and 41+0 weeks gestation, are scheduled for or intend to be scheduled for induction of labor, have a singleton pregnancy, and are eligible for vaginal delivery.

Not a fit: Patients who plan a repeat cesarean or trial of labor after cesarean, have multiple gestation, major fetal anomalies, are not eligible for vaginal delivery (for example fetal malpresentation or abnormal placentation), do not intend to labor, or are non–English speaking are excluded and unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, earlier consent could reduce distress and improve preparedness and education for patients who unexpectedly need a cesarean delivery.

How similar studies have performed: Practices vary widely and this specific randomized comparison of consent timing is novel, with limited prior evidence showing whether earlier consent improves patient experience.
