Elective induction vs. spontaneous labor associations and outcomes

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Public Health

Background:

• Elective labor induction is a common obstetric procedure.
• Understanding its impact on maternal and neonatal outcomes in low-risk populations is crucial for informed clinical decision-making.

Purpose of the Study:

• To compare the factors and outcomes of elective labor induction versus spontaneous labor in low-risk women.
• To identify associations between elective induction and interventions, delivery mode, and maternal/neonatal outcomes.

Main Methods:

• Retrospective analysis of a birth certificate database (11,849 low-risk women).
• Defined low-risk criteria: singleton, vertex, 37-41 weeks gestation, no prior cesarean, no medical/obstetric contraindications.
• Used univariate and multiple logistic regression to analyze demographic and obstetric factors, interventions, and outcomes.

Main Results:

• Elective induction was associated with increased odds of epidural anesthesia, cesarean delivery, and nonreassuring fetal heart rate patterns.
• No significant increase in odds for cephalopelvic disproportion, instrumental delivery, or adverse neonatal outcome.
• Maternal length of stay was 0.34 days longer for induced labors (p < 0.0001).

Conclusions:

• Elective labor induction in low-risk women is independently associated with increased intrapartum interventions and cesarean deliveries.
• Maternal length of stay is longer following elective induction.
• Neonatal outcomes are not adversely affected by elective labor induction compared to spontaneous labor.
