Universal aspirin dispensation at the first prenatal visit reduced preeclampsia with severe features by 29% in high-risk pregnancies.
2
The study involved 18,457 patients before and after aspirin implementation, showing a decrease in severe preeclampsia rates from 7% to 5%.
3
Aspirin administration also led to a decline in gestational hypertension rates from 21% to 19% and reduced preterm delivery before 37 weeks.
4
Postpartum hemorrhage rates decreased from 9.5% to 8.9%, and placental abruption rates remained stable at less than 1%.
5
The findings suggest aspirin may delay or prevent severe preeclampsia, but results may not generalize to other populations.
