US Physician and Midwife Adherence to Active Management of the Third Stage of Labor International Recommendations

Introduction The prevalence of postpartum hemorrhage has increased in the United States despite the international promotion of active management of the third stage of labor. Adherence to the international recommendations in the United States is unclear. It is also not known how the components of active management are related to other practices that may be used during the third stage of labor. The purpose of this study was to determine routine practice patterns for managing the third stage of labor in the United States. Methods A randomized national survey was conducted of certified nurse-midwives/certified midwives, certified professional midwives, obstetricians, and family physicians who self-reported third-stage practices. Descriptive analyses and partial correlations were used to determine differences in practice patterns between midwives and physicians. A 2-step clustering algorithm was used to identify clusters of third-stage practices. Results A total of 1243 clinicians responded. Uterine massage after placenta expulsion was reportedly used at almost every birth by all provider types. Median use of cord traction and oxytocin administration by all provider types was 80% and 90% of births, respectively. Cluster analysis of these and other interventions used during the third stage of labor revealed 4 distinct clusters of practices ranging from primarily a hands-off at one extreme to high-intervention approaches at the other extreme. The other 2 clusters were defined by practices that fell between those extremes. Discussion Determination of how, and under what conditions, clinicians decide when to use particular techniques to manage the third stage of labor and how these techniques influence the incidence of postpartum hemorrhage, is necessary. The clusters of practice combinations that emerged in this study suggest that there are extreme variations in clinician practices during management of the third stage of labor.
