Maternal morbidity and mortality associated with epilepsy.

Prior research demonstrated large increased risk for maternal mortality among women with epilepsy. The objective of this study was to estimate risk for adverse maternal outcomes during delivery hospitalizations among women with epilepsy. Truven Health MarketScan databases were used to compare risk for adverse maternal outcomes during delivery hospitalizations based upon whether there was diagnosis of epilepsy and receipt of anti-epileptic drugs prior to delivery. Outcomes included: (i) death during delivery hospitalization, (ii) severe maternal morbidity, (iii) cesarean delivery, (iv) postpartum hemorrhage, (v) placental abruption, (vi) preeclampsia, (vii) preterm delivery, (viii) premature rupture of membranes, and (ix) stillbirth. Adjusted models including hospital and demographic factors were performed with adjusted risk ratios (aRR) with 95% CIs as measures of effect. Women with epilepsy prior to delivery who received antiepileptic drugs ( No significant difference in mortality risk was found for women with epilepsy. Increased risk for other adverse maternal outcomes for women with epilepsy on antiepileptics was modest.
