Summary

Obstetric intervention rates for low-risk women showed mixed trends, with decreases in episiotomy and forceps delivery but increases in membrane rupture and continuous electronic fetal monitoring (EFM). Further study is needed to understand these evolving physician practice patterns.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Healthcare Quality Improvement

Background:

  • Trends in obstetric interventions for low-risk pregnancies are influenced by evolving medical practices and recommendations.
  • Understanding these trends is crucial for optimizing maternal and neonatal outcomes.

Purpose of the Study:

  • To analyze changes in the rates of various obstetric interventions over a three-year period in low-risk women.
  • To investigate whether obstetric intervention rates decreased as hypothesized.

Main Methods:

  • Retrospective review of hospital records from three University of Toronto-affiliated hospitals.
  • Inclusion criteria focused on low-risk pregnancies (Grade A) identified via the Ontario Antenatal Record.
  • Data collected on artificial membrane rupture, induction, augmentation, epidural anesthesia, continuous electronic fetal monitoring (EFM), instrumental delivery, episiotomy, and cesarean section rates.

Main Results:

  • Significant decreases observed in episiotomy and low forceps delivery rates for both family physicians and obstetricians.
  • Epidural anesthesia rates declined significantly among obstetricians.
  • Increases noted in artificial membrane rupture, induction, and continuous EFM, with EFM increase being significant in the obstetrician group.
  • No significant changes in augmentation, midforceps, vacuum extraction, or cesarean section rates were found.

Conclusions:

  • Observed obstetric intervention trends partially align with literature but lack clear medical evidence for some changes.
  • The unpredictable nature of these trends highlights the need for further research into the underlying reasons for shifts in physician practice patterns.
  • Investigating the drivers behind these obstetric trends is essential for evidence-based practice and improved patient care.
