Abstract

Objective: The aim of this national study was to examine the incidence of preterm pre-eclampsia (PE) and the proportion of women with risk factors for PE, according to the criteria suggested by the National Institute for Health and Care Excellence (NICE) and the American College of Obstetricians and Gynecologists (ACOG), during a 10-year period in Denmark.

Methods: Data from The Danish National Patient Registry and the Danish Medical Birth Registry were used to obtain the incidence of preterm PE with delivery < 37 weeks' gestation and risk factors for PE for all deliveries in Denmark from 1 January 2008 to 31 December 2017. The proportion of women with at least one high-risk factor and/or at least two moderate-risk factors for PE, according to the NICE and ACOG criteria, and the detection rate for preterm PE were examined. Race, socioeconomic status and the woman's weight at birth were not available from the registries used, and information on Type-2 diabetes was found to be invalid.

Results: Of the 597 492 deliveries during the study period, any PE was registered in 3.2%, preterm PE < 37 weeks in 0.7% and early-onset PE < 34 weeks' gestation in 0.3%. These proportions remained largely unchanged from 2008 to 2017. Overall, the NICE criteria were fulfilled in 7.5% of deliveries and the ACOG criteria in 17.3%. In the total population, the NICE criteria identified 47.6% of those with preterm PE and the ACOG criteria identified 60.5%. The current criteria for offering aspirin treatment in Denmark largely correspond to having at least one NICE high-risk factor. In 2017, a total of 3.5% of deliveries had at least one NICE high-risk factor, which identified 28.4% of cases that later developed preterm PE.

Conclusions: The incidence of preterm PE remained largely unchanged in Denmark from 2008 to 2017. Prediction of PE according to high-risk maternal factors could be improved by addition of moderate-risk factors. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.
