Introduction:The purpose of this study was to increase understanding of the components of the US birth center model of prenatal care and how the birth center prenatal care model contributes to birthing people's confidence for physiologic childbirth. Methods:This was a qualitative descriptive study using semistructured interviews with individuals who gave birth in freestanding birth centers. Birthing people were recruited from freestanding birth centers in a Midwestern US state and were between the ages of 18 and 42, were Englishspeaking, and had experienced a birth center birth within the previous 6 months. Interviews were transcribed and analyzed using Glaser's constant comparative method.Results: Twelve women who gave birth in birth centers, representing urban and rural settings, participated. Four core categories were identified encompassing the components of birth center prenatal care and how the birth center model contributes to women's confidence for physiologic birth: birth center culture and processes, midwifery model of care within the birth center, internal influences, and outside influences.Discussion: Women who gave birth in birth centers believed that the birth center culture and environment, the midwifery model of care in the birth center, internal influences including the belief that birth is a normal physiologic process, and outside influences including family support and positive birth stories contributed to their confidence for physiologic birth.

ObjectiveThe purpose of this study was to describe US freestanding birth center models of prenatal care and to examine how the components of this care contribute to birthing people's confidence in their ability to have a physiologic birth.DesignThis was a qualitative descriptive study utilizing semi‐structured interviews with birth center midwives. Data were analyzed using thematic analysis, constant comparative method and consensus coding to ensure rigor.Setting and ParticipantsMidwives from six urban and rural freestanding birth centers in a Midwestern US state were interviewed. Twelve birth center midwives participated.FindingsSix themes emerged: the birth center physical space and organization of care, dimensions of midwifery care within the birth center, continuity of care and seamless service, the empowered birthing person, physiologic birth as normative, and the hospital paradigm and US cultures of birth.Key ConclusionsWe identified significant components of birth center models of prenatal care that midwives believe enhance birthing people's confidence for physiologic childbirth. These components may be considered for application to other settings and may improve perinatal care and outcomes.
