Development of a Nationally Scalable Model of Group Prenatal Care to Improve Birth Outcomes: "Expect With Me"
Study Details
Study Description
Brief Summary
This study addresses the intractable challenges of adverse birth outcomes, including preterm delivery and low birthweight, by proposing the development, implementation and evaluation of a model of group prenatal care that could be scaled nationally. Group prenatal care models have been demonstrated through rigorous research to provide significantly improved birth outcomes with implications for maternal-child health and substantial cost savings. However, group prenatal care is currently available to only a small fraction of the more than four million women who give birth annually in the US. Through the development, implementation and evaluation of a new model of group prenatal care, we will create an outcomes-focused model of group prenatal care that will be scalable nationally with an eye toward improving US birth outcomes.
The long-term objective of the proposed study is to reduce the risk for adverse perinatal outcomes during and after pregnancy among women and families receiving prenatal care in health centers in 3 geographic locations serving vulnerable populations: Hidalgo County Texas, Nashville Tennessee, and Detroit Michigan. We will develop, disseminate, and evaluate a new and improved model of group prenatal care, "Expect with Me," based on our previous research on group models of prenatal care, which has already yielded favorable behavioral and biological results in two randomized controlled trials.
We hypothesize that, relative to women who receive standard individual prenatal care, the women who receive "Expect with Me" group prenatal care will be significantly more likely to:
-
have better perinatal outcomes, including better health behaviors during pregnancy (e.g., nutrition, physical activity), better birth outcomes (e.g., decreased preterm labor, low birthweight, Neonatal Intensive Care Unit stays), and better postpartum indicators (e.g., increased breastfeeding);
-
report greater change in risk-related behaviors and psychosocial characteristics that could be considered potential mechanisms for the program's effectiveness;
-
have lower rates of sexually transmitted diseases and rapid repeat pregnancy one year postpartum;
-
have lower healthcare costs through improved outcomes (e.g., appropriate care utilization, fewer complications, reduced NICU admissions/length of stays)
Comparisons based on propensity-score matched sample of women receiving standard individual prenatal care at the same clinical sites.

Detailed Description
This study addresses the intractable challenges of adverse birth outcomes, including preterm delivery and low birthweight, by proposing the development, implementation and evaluation of a model of group prenatal care that could be scaled nationally. Group prenatal care models have been demonstrated through rigorous research to provide significantly improved birth outcomes with implications for maternal-child health and substantial cost savings. However, group prenatal care is currently available to only a small fraction of the more than four million women who give birth annually in the US. Through the development, implementation and evaluation of a new model of group prenatal care, we will create an outcomes-focused model of group prenatal care that will be scalable nationally with an eye toward improving US birth outcomes.
Specific Aims:
The long-term objective of the proposed study is to reduce the risk for adverse perinatal outcomes during and after pregnancy among women and families receiving prenatal care in health centers in 3 geographic locations serving vulnerable populations: Hidalgo County Texas, Nashville Tennessee, and Detroit Michigan. We will develop, disseminate, and evaluate a new and improved model of group prenatal care, "Expect with Me," based on our previous research on group models of prenatal care, which has already yielded favorable behavioral and biological results in two randomized controlled trials. The overall objective of this project is to improve maternal health and reduce adverse birth outcomes. We will meet this objective by achieving three specific goals:
-
Develop a new and improved model of group prenatal care, including curriculum, training materials, IT infrastructure and marketing materials to support broad adoption of group prenatal care, enhance consumer experience, monitor patient outcomes, and ensure national scalability.
-
Implement group prenatal care in three communities at high risk for adverse perinatal outcomes (Hidalgo County TX, Nashville TN, Detroit MI), engaging and training providers in group facilitation and the established curriculum, engaging patients through improved in-reach and outreach strategies, and implementing IT infrastructure to improve uptake, patient experience, and sustainability through the monitoring of patient outcomes.
-
Evaluate the effect of implementing group prenatal care through a rigorous process and outcome evaluation that identifies any barriers to national scalability and examines maternal health and birth outcomes and resultant cost implications.
Specific Study Hypotheses
We hypothesize that, relative to women who receive standard individual prenatal care, the women who receive "Expect with Me" group prenatal care will be significantly more likely to:
-
have better perinatal outcomes, including better health behaviors during pregnancy (e.g., nutrition, physical activity), better birth outcomes (e.g., decreased preterm labor, low birthweight, Neonatal Intensive Care Unit stays), and better postpartum indicators (e.g., increased breastfeeding);
-
report greater change in risk-related behaviors and psychosocial characteristics that could be considered potential mechanisms for the program's effectiveness;
-
have lower rates of sexually transmitted diseases and rapid repeat pregnancy one year postpartum;
-
have lower healthcare costs through improved outcomes (e.g., appropriate care utilization, fewer complications, reduced NICU admissions/length of stays)
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Expect With Me group prenatal care receiving prenatal care through an Expect With Me group |
Behavioral: Expect With Me group prenatal care
Expect With Me group prenatal care was designed based on: principles of group care; evidence from RCTs demonstrating improved birth outcomes; ACOG clinical guidelines; and research on patient and provider engagement through technology. Designed with national dissemination as a primary consideration, Expect With Me incorporates best evidence-based aspects of existing models of group care, with a novel IT platform to improve patient engagement and support, enhance health behaviors and decision making, connect providers and patients, and improve health service delivery. Expect With Me provides care to groups of 8-12 women of the same gestational age, implemented after initial individual assessment through delivery. Group visits are 90-120 minutes each, and follow a structured curriculum that incorporates standard content of prenatal care, and emphasizes critical health issues relevant to pregnancy, such as nutrition, physical activity, stress/mental health and sexual health.
