Motivation towards first trimester screening for preeclampsia among pregnant women in Denmark: A cross-sectional questionnaire study.

The aim of this cross-sectional questionnaire study was to investigate motivation to participate in a possible new screening for preeclampsia in the first trimester of pregnancy among Danish pregnant women through a questionnaire based on Theory of Planned Behavior developed for this specific purpose. The new screening combines maternal characteristics with mean arterial pressure, uterine artery pulsatility index and biochemical markers to predict the risk of preeclampsia, whereas the current Danish screening uses maternal characteristics alone. Participation was offered to a proportion of women attending a first or a second trimester screening scan at two University Hospitals in Copenhagen. The questionnaire was set up in REDCap® and answers were entered directly into the database, which was accessed via a QR-code. We invited 772 pregnant women to participate in the questionnaire survey between November 2021 and April 2022 at Copenhagen University Hospital Rigshospitalet (study site one) (n = 238) and Copenhagen University Hospital Hvidovre (study site two) (n = 534). The response rate was 71.8% (171/238) at study site one and 33.9% (181/534) at study site two. A total of 352 women were included in the study (total participation rate 45.6%). Most women had a positive attitude towards preeclampsia screening in pregnancy, and 99.4% said they would participate in a risk assessment for preeclampsia if given the opportunity. A total of 97.4% answered "yes" to whether a first trimester preeclampsia screening should be offered to all pregnant women in Denmark. Positive motivation to participate in preeclampsia screening was correlated with having a network with a positive attitude towards preeclampsia screening. The results of this study indicate that Danish pregnant women have a positive attitude towards participation in a first trimester screening for preeclampsia. This observation might be useful in relation to possible future implementation in Denmark.
