Objective: Determine the diagnostic performance of a preeclampsia prediction nomogram in pregnant women attended at the Dos de Mayo National Hospital during the period from January 2016 to July 2019. Method: Study of diagnostic tests. There was a sample of 513 patients, 225 patients with a diagnosis of pre-eclampsia and 288 patients without such diagnosis were selected. The analysis of the data obtained was carried out in STATA v.14, obtaining the values of sensitivity, specificity, PPV and NPV. Results: The ROC curve was analyzed obtaining an AUC of 0.91 (95% CI: 0.89 - 0.93), obtaining 187 points as the cut-off point for the best diagnostic performance, with a sensitivity of 81.33% and a specificity of 85.76%. Conclusions: The preeclampsia prediction nomogram has a good diagnostic performance for pregnant women attended at the Gynecology and Obstetrics service of the Dos de Mayo National Hospital.
