RÉSUMÉ
INTRODUCTION: Reproductive-age women with bleeding disorders (BDs) are underdiagnosed and understudied, despite their increased risk for adverse health outcomes and pregnancy complications. AIM: This study examines pregnancy outcomes and obstetric complications of Utah women with BDs. METHODS: This retrospective cohort study utilized linked birth records and clinical billing data from two large Utah healthcare systems. Utah residents who had their first birth at > 20 weeks gestation (2008-2015) and who received non-emergent care within either system before delivery were included (n = 61 226). Multivariable logistic regression models were used to examine relationships between BDs and neonatal and obstetric outcomes. RESULTS: A total of 295 women (.48%) were included in the BD study population. Women with BDs had significantly increased odds of preterm birth (aOR 1.85, 95% CI 1.32-2.60), Caesarean delivery (aOR 1.38, 95% CI 1.06-1.79), postpartum blood transfusion (aOR 2.55, 95% CI 1.05-6.22), unplanned postpartum hysterectomy (aOR 33.96, 95% CI 7.30-157.89) and transfer to an intensive care unit (aOR 18.18, 95% CI 7.17-46.08). All of the women with BDs who experienced these serious complications were not diagnosed with a BD until the year of their first birth. Additionally, those with BDs were more likely to experience maternal and infant mortality. CONCLUSION: Women with BDs had an increased risk for preterm birth, Caesarean delivery, blood transfusion, unplanned hysterectomy, intensive care unit admission, maternal and infant mortality. Those who were not diagnosed with a BD before the year of their first birth were at an increased risk for serious pregnancy complications.
