Multicenter impact analysis of a model for predicting recurrent early-onset preeclampsia: A before-after study

Objective: This study aims to determine the impact of using a prediction model for recurrent preeclampsia to customize antenatal care in subsequent pregnancies. Methods: We compared care consumption, pregnancy outcomes, and self-reported health state of two risk-based subgroups, and compared these to a reference group receiving standard care. Results: We included a total of 311 women from 12 hospitals. Compared to standard care, recurrence-risk guided care did not lead to different outcomes or self-perceived health. Conclusion: Our study exemplifies that recurrence-risk-based stratification of antenatal care in former preeclampsia patients is feasible; it does not lead to worse pregnancy outcomes.
