Combined first-trimester screening for pregnancy complications

The Combined First Trimester Screening

Institute of Health Information and Statistics of the Czech Republic · NCT07015203

This project tests a standardized first-trimester screening to see if it can identify pregnant women at 11–13 weeks who are at higher risk for preeclampsia, fetal growth restriction, chromosomal problems, and other serious complications.

What this trial studies

This national, prospective multicenter pilot will enroll about 2,000 pregnant women in the Czech Republic at 11–13 weeks of gestation. It collects maternal history, ultrasound measurements, biochemical and biophysical parameters and uses FMF‑certified software to calculate individual risks for preeclampsia, fetal growth restriction and common chromosomal aneuploidies. Collected clinical parameters will be linked with the Czech National Health Information System to enable unified recording, analysis and planning for reimbursement mechanisms. The project aims to standardize first‑trimester evaluation across participating centers and improve access to quality prenatal care.

Who should consider this trial

Good fit: Women aged 18 or older in the first trimester of pregnancy (11th–13th gestational week) who sign informed consent and agree to personal data processing are eligible.

Not a fit: Women under 18, those outside the 11–13 week window, or those who decline consent or data-sharing are not eligible and would not receive benefit from this screening.

Why it matters

Potential benefit: If successful, the program could identify high-risk pregnancies earlier and help ensure more consistent care and preventive treatment, potentially reducing severe obstetric complications.

How similar studies have performed: Similar FMF-based combined first-trimester screening approaches have been adopted internationally and have demonstrated improved detection of preeclampsia risk and chromosomal aneuploidies when properly implemented.
