Objectives: Preeclampsia (PE) is a pregnancyrelated hypertensive disorder that can lead to severe complications and adverse maternal and fetal outcomes. This study aimed to estimate the economic impact of integrating the sFlt-1/PlGF ratio into Uruguay's healthcare system as part of routine clinical practice for diagnosing., Material and Methods: A decision tree model was used to estimate the annual economic impact on the Uruguayan healthcare system for a hypothetical cohort of women with suspected PE. This included relevant costs associated with diagnosis, monitoring, and treatment from the initial presentation of suspected PE until childbirth. The study analyzed the annual costs under two scenarios: the standard of care and a scenario incorporating the sFlt-1/PlGF ratio for PE, using 2022 as the reference year. Various deterministic and probabilistic sensitivity analyses were performed., Results: The economic model estimated that the implementation of the sFlt-1/PlGF ratio could save the Uruguayan healthcare system $95,432,678 Uruguayan pesos (2,320,269 United States Dollars [USD]) annually, representing a 5 % reduction in costs compared with the standard of care. These savings were primarily due to a reduction in hospitalizations of women with suspected PE. The estimated economic impact equated to an annual net saving of approximately $10,602 Uruguayan pesos (258 USD) per patient., Conclusions: The introduction of the sFlt-1/PlGF ratio into the Uruguayan healthcare system is likely to generate savings due to the optimization of the management of hospitalizations for women with suspected preeclampsia (PE). However, the potential for savings will primarily depend on the current hospitalization rate of these women (the efficiency of managing high-risk PE pregnancies) and the length of stay for hospitalized women.
