Risk factors and recurrence risk for postpartum hemorrhage due to dystocia


Key clinical point: Recurrence risk was highest for postpartum hemorrhage (PPH) due to dystocia, with maternal age, birth weight, and previous cesarean section being significant risk factors for PPH due to dystocia.

Major finding: The recurrence risk was highest for PPH due to dystocia (adjusted odds ratio [aOR] 6.8; 95% CI 6.3-7.4), with a prior history of cesarean section (aOR 6.08; 95% CI 5.82-6.35), older maternal age (30-34 vs 25-29 years: aOR 1.42; 95% CI 1.38-1.46), and higher birth weight (4000-4499 vs 3500-3999 g: aOR 1.98; 95% CI 1.92-2.03) being significant risk factors for PPH due to dystocia.

Study details: This population-based cohort study included 3,003,025 singleton deliveries with spontaneous onset or induction of labor (gestational age at delivery 22 weeks), of which 277,746 were complicated by postpartum hemorrhage.
