Abstract

Objective We sought to describe details of labor induction, including precursors and methods, and associated vaginal delivery rates.Study design This was a retrospective cohort study of 208,695 electronic medical records from 19 hospitals across the United States, 2002 through 2008.Results Induction occurred in 42.9% of nulliparas and 31.8% of multiparas and elective or no recorded indication for induction at term occurred in 35.5% and 44.1%, respectively. Elective induction at term in multiparas was highly successful (vaginal delivery 97%) compared to nulliparas (76.2%). For all precursors, cesarean delivery was more common in nulliparas in the latent compared to active phase of labor. Regardless of method, vaginal delivery rates were higher with a ripe vs unripe cervix, particularly for multiparas (86.6-100%).Conclusion Induction of labor was a common obstetric intervention. Selecting appropriate candidates and waiting longer for labor to progress into the active phase would make an impact on decreasing the national cesarean delivery rate.

  • Enrollment criteria targeting seemingly healthy pregnancy increased the ability to observe spontaneously initiated birth, with a lower induction/pre-labor cesarean rate than the U.S. overall.

    “our enrollment criteria, which targeted seemingly healthy pregnancy, did increase our ability to observe spontaneously-initiated birth, as the rate of induction of labor/pre-labor cesarean was 40% in our sample compared to an overall U.S. rate of greater than 50% (Laughon et al., 2012; Zhang et al., 2010).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
