The intent and delivery of prenatal care have evolved since its formal inception in the early 1900s. Group prenatal care offers an alternative care delivery model to the currently dominant prenatal care model. The group model has been associated with a number of improved perinatal outcomes including decreased preterm birth, higher birth weight, improved breast-feeding initiation and duration, decreased cesarean delivery, and greater patient satisfaction. This article outlines the tenets of CenteringPregnancy, the current dominant form of group prenatal care, reviews literature regarding perinatal outcomes related to group prenatal care, suggests future research agendas, and highlights relevant considerations when implementing this alternate model of prenatal health care delivery.
