Community for Antepartum Patients (CAP): Establishing an Inpatient Model for Group Prenatal Care at Duke (2021-2022)


Preterm birth – delivery before 37 weeks gestational age – is a major cause of illness and death in newborn babies’ first month. In the U.S., about 10 percent of pregnancies result in preterm deliveries; rates are 48 percent higher among Black women.

About a third of preterm deliveries are preceded by preterm prelabor rupture of membranes (PPROM). Management of PPROM involves hospital admission to the antepartum unit until delivery, which can span months. While any hospitalization is stressful, spending a long time in the hospital before giving birth can be particularly difficult for patients, who must be socially isolated while they are facing a new diagnosis with an unpredictable course. These mothers have a shared experience of loss of their normal support systems, work and sense of autonomy.

Group prenatal care models such as CenteringPregnancy© have shown improved pregnancy outcomes and have been shown to reduce racial disparities in preterm births. In a pilot study of an inpatient centering model for the Duke Hospital antepartum service, women enjoyed being brought together to create a community. Participants had significantly longer pregnancies, with greater effect among Black women. There were also improvements in breastfeeding rates after the women gave birth.

Project Description

This project will adapt the CenteringPregnancy group model, traditionally used as an outpatient service, to an inpatient antepartum service by expanding a pilot study performed in 2019-2020. The team will develop and implement a sustainable inpatient antepartum intervention through Centering groups that can benefit both pregnant women and their babies by increasing length of pregnancy and breastfeeding rates. The intervention will also foster community in a way that supports emotional and mental well-being.

Providers will recruit current patients and enroll them in inpatient Centering groups. Prior to their first Centering session, patients will complete a survey to assess their emotional and mental state, preparedness for the Neonatal Intensive Care Unit (NICU) and plans regarding breastfeeding. 

Patients will participate in weekly one-hour virtual Centering group sessions. Sessions will consist of a brief mindfulness activity followed by discussion and education about a particular topic or concern. These could include common antepartum diagnoses, pregnancy loss, breastfeeding, coping with separation from family and caring for a NICU baby. Team members will be directly involved in the weekly sessions, rotating roles on a monthly basis.

Patients will then complete surveys at the end of their hospitalization and six weeks postpartum to assess their emotional/mental state and feeling of preparedness for caring for a NICU baby. Prior to discharge, patients will participate in an interview about hospital well-being and the impact of Centering participation. 

Team members will analyze the data to assess the association between Centering groups and patients’ emotional well-being, preparedness for infant care and use of breastfeeding. The primary quantitative outcomes will be length of pregnancy. Secondary outcomes will include factors of maternal morbidity such as sepsis, blood transfusion or readmission. These measures will be compared to controls in the Duke Hospital PPROM database. A racial subanalysis will be conducted to compare the outcomes across different groups.
