NCT03941886

Brief Summary

This implementation study aims to evaluate the efficacy, acceptability, and safety of first-trimester screening and prevention for preterm-preeclampsia. It is a multicenter stepped wedge cluster randomized trial including maternity / diagnostic units from ten regions in Asia. The study involves a period where no intervention will take place at all recruiting units, and then at regular intervals, one cluster will be randomized to transit from non-intervention group to intervention group in which first-trimester screening for preterm-preeclampsia by the Bayes based method followed by the commencement of low-dose aspirin in high-risk women.
