Objective: The pregnancy, delivery, and neonatal outcomes of pregnancies complicated by cystic fibrosis (CF) have yet to be evaluated in a prolonged, population-based study. We sought to evaluate the obstetric and neonatal outcomes in pregnant patients with CF using a national population database.
Study Design: Retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). All women who delivered or had a maternal death in the US (2004-2014) were included in the study. Pregnancy, delivery, and neonatal outcomes were compared between women with an ICD-9 diagnosis of cystic fibrosis to those without.
Results: Overall, 9 096 159 women met the inclusion criteria. Of these, 629 women (6.9/100000) had CF. Women with CF were more likely to be younger and have pregestational diabetes mellitus compared to those without. CF in pregnancy was associated with an increased risk of developing gestational diabetes mellitus [aOR 3.20 (95 %CI 2.48-4.15), p = 0.0001], placenta previa [aOR 2.74 (95 %CI 1.30-5.79), p = 0.008], preterm delivery [aOR 2.17 (95 %CI 1.71-2.77), p = 0.0001], operative vaginal delivery [aOR 1.59 (95 %CI 1.17-2.16), p = 0.003], and death [aOR 86.41 (95 %CI 30.91-241.58), p = 0.0001], and a decreased likelihood of having a spontaneous vaginal delivery [aOR 0.80 (95 %CI 0.66-0.97), p = 0.02]. Patients with CF were more likely to experience deep venous thrombosis [aOR 7.64 (95 %CI 1.90-30.72), p = 0.004] and disseminated intravascular coagulation [aOR 3.68 (95 %CI 1.37-9.87), p = 0.01] compared to those without. The risk of delivering a fetus with congenital anomalies was similar between groups.
Conclusion: Pregnant patients with CF have an increased risk of developing adverse maternal and delivery outcomes. As such, these patients should receive vigilant surveillance during pregnancy.
