Key clinical point: Analysis over 2 decades demonstrated trend changes in individual contribution of risk factors for postpartum hemorrhage, with perineal or vaginal tears increasing, large for gestational age neonate decreasing, and other risk factors remaining stable.
Major finding: The incidence of postpartum hemorrhage increased from 0.5% in 1988 to 0.6% in 2014. Among risk factors for postpartum hemorrhage, perineal or vaginal tear demonstrated a rising trend (P = .01), delivery of large for gestational age neonate demonstrated a declining trend (P < .001), and other risk factors, such as preeclampsia, vacuum extraction delivery, and retained placenta, remained stable during the study period.
Study details: Findings are from a population-based, retrospective, nested, case-control study including 285,992 pregnancies, of which 1684 were complicated by postpartum hemorrhage.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
