IntroductionMidwives and physicians incorporate their knowledge, experiences, and other variables in making clinical decisions. Variations in the management of the third stage of labor may be a result of variables that influence providers' decision making. The purpose of this study was to describe variables that influence US midwives' and physicians' management of the third stage of labor.
MethodsA randomly selected national sample of certified nurse-midwives and certified midwives, certified professional midwives, obstetricians, and family physicians was surveyed about the extent to which maternal characteristics, maternal history, and current birth characteristics influence their third-stage management. The extent of influence was defined in terms of always to never altering management. Descriptive summaries, group comparisons, and partial correlations were used to determine differences in influences between midwives and physicians. One free-text question was analyzed using qualitative methods.
ResultsA total of 1243 clinicians responded. There was considerable variability in the response patterns in that the same variable was reported to always alter management during the third stage of labor for some participants yet did not influence the management practices of others at all. Differences between responses from midwives and physicians were explored as a possible explanation for some of the variability. In response to the free-text inquiry about variables that most influenced changes in participants' usual management of the third stage, the participants most often included active bleeding, current recommendations or guidelines, and maternal or family preferences.
DiscussionThis study identifies variables reported as influencing clinical decision making during the third stage of labor. Therefore, these variables are important to consider when evaluating interventions and outcomes related to management of the third stage of labor and any attempts to design new interventions. The findings are descriptive of practice; they are not intended to guide changes in practice.
