Assessment of the ability to predict complications of the Risk Factor Scale for Pre-eclampsia Complications and the fullPIERS scale in pregnant women in a Hospital in Lima, Peru.

OBJECTIVES.: To evaluate the ability of the Risk Factor Scale for Preeclampsia Complications (RFSPC) and the fullPIERS (Pre-eclampsia Integrated Estimate of RiSk) scale to predict complications of preeclampsia in pregnant women diagnosed with preeclampsia who were admitted to the obstetrics and gynecology department of a referral hospital, from October 2021 to December 2022. MATERIALS AND METHODS.: This was a retrospective cohort design study. Data was collected from the medical records of patients diagnosed with preeclampsia, and both scales (RFSPC and fullPIERS) were applied. With these results, the sensitivity, specificity and the area under the ROC curve (AUC) were obtained by taking different cut-off points. The best score was selected as the one with the highest AUC. The differences between the scales were explored by comparing their AUCs. RESULTS.: We included 367 pregnant women. The RFSPC had a sensitivity of 71%, a specificity of 73% and an AUC of 0.722 with a cutoff point of 3 points. Whereas the fullPIERS scale showed 76%, 84% and 0.804 respectively with a cutoff point of 0.75%. CONCLUSIONS.: Both scales can be useful for identifying pregnant women at risk of complications with cutoff points different from those defined internationally.
