The calculator provided on this webpage is intended to predict a person’s risk of readmission related to hypertension during pregnancy or after delivery. The data used to derive this prediction model and calculator included 32,645 women who delivered from 2009-2018 at a single-site Midwestern academic center. One hundred and seventy women in this dataset were readmitted in the postpartum period due to a hypertension-related diagnosis. The Random forest method used to identify the key predictive variables and final model achieved a sensitivity of 85%, specificity of 79%, and a balanced accuracy of 82% for predicting readmission. This calculator was created for research and educational purposes with the intention to improve the prediction or identification of women at risk for readmission due to hypertension during or after pregnancy and delivery.
