The study defines a new model of prenatal care called OB Nest which will be compared to the traditional model of prenatal care. OB nest is intended to create an experience for patients that feels more connected and patient-centered, allowing the patient to visit the clinic less frequently while offering increased communication with the OB nurses and providers through new tools provided to the patient. The goal of the project is to promote patient-centered care through a new prenatal care program based on constant and direct support from a nursing team, meeting the on-demand needs of expecting mothers as they rise, and as thus, redesigning the need and timing of on-site appointment with providers. Pregnant women randomized to the OB Nest cohort will see the number of pre-planned visits with their providers decreased and replaced with more direct and constant support and interaction with an assigned nursing team.

OB Nest is a model designed to promote increased patient-centered care during pregnancy. OB Nest care will allow for more flexibility, decrease interruptions to your productivity, while continuing to maintain safety for you and your infant. This model of care is anticipated to allow you more access to your health care team during your pregnancy.

This study will compare OB Nest, a new model of prenatal care, to the existing traditional model of prenatal care. The plan is to have about 300 low-risk mothers take part in this study. Eligible patients will be randomized to one of two groups; The Traditional Prenatal care Group or the OB Nest Group. Mothers will have an equal chance of being assigned to the OB Nest group. Mothers randomized to the OB Nest intervention will be assigned to a nursing care team comprised of one to three nurses and see their initial eleven planned appointments with their provider reduced to six. Mothers will still be able to request additional in-office visits with their provider and/or the provider require additional in-office visits to monitor mother and infants safety/care.
