Abstract

The lack of evidence-based practice (EBP) in US hospitals can exacerbate poor maternal and newborn outcomes, resulting in more expensive care. Nurse-Midwifery is a growing profession, with over 11,000 practitioners, that tend to promote EBP, resulting in documented positive outcomes. Focused studies of how these practitioners use EBP in the achievement of these outcomes is severely lacking. The goal of this research was to understand how nurse-midwives practice in the current US hospital system, focusing on the processes that encourage this health provider to implement EBP. This study was framed by Bourdieu's Theory of Practice which explains that behavior results from a combination of the values and beliefs (habitus), power to act (capital), and environment (field) of the individual. The primary aim of this research was to describe the nurse-midwifery process of care occurring while this provider implements EBPs in birth management. The techniques of constructionist grounded theory were implemented with the transcripts of face to face interviews with 19 nurse-midwives working fulltime and delivering in the hospital setting, in the southeastern United States. The new theory of Shaping Birth describes and explains the nurse-midwifery management of labor and birth care through the processes of connecting, protecting, and intervening. Implementing the techniques of situational analysis and discourse analysis resulted in the description of nurse-midwifery values, beliefs, and the environments (social, structural, and interprofessional) that influence their care within the hospital system. The contextualized theory of Shaping Birth was then analyzed in conjunction with descriptions of the implementation of labor induction/augmentation, medical pain relief and the decision to deliver via caesarean by the nurse-midwives to provide additional depth to the implementation of the theory with EBPs. The information gained from this study will provide the groundwork for a broader research plan aimed at minimizing the underuse, overuse, and misuse of intervention in obstetrics while increasing the use of evidenced-based maternity care. This can result in increased efficiency in maternity care with improvements in effectiveness, safety, quality and team work.
