The Sentinel System can be used to address numerous questions of importance to FDA during the COVID-19 pandemic. One population of significant interest for study is pregnant people. Evidence suggests that pregnant people are more likely to experience severe illness related to respiratory infections, including COVID-19, than nonpregnant people (1,2). Little information is available to support understanding the natural history of COVID-19 disease in pregnant people, or the impact of COVID-19 treatment upon pregnant people or the developing fetus.
To address vulnerable populations, including pregnant people, Sentinel published a COVID-19 Natural History Master Protocol, designed to identify multiple COVID-19 cohorts to support a variety of on-demand queries and subsequent descriptive and inferential studies. The European Medicines Agency (EMA) has also funded a project, called “COVID-19 infectiOn aNd medicineS In pregnancy” (CONSIGN) which has drafted a protocol to study the natural history of COVID-19 disease in pregnant people. The CONSIGN study is currently being implemented in varied data sources across eight European countries.
This project will implement the following (three) aims of the CONSIGN protocol:
- To estimate the prevalence of medicines used and compare this among pregnant people with COVID‐19, pregnant people without COVID‐19, and nonpregnant people with COVID‐19.
- To describe severity and clinical outcomes of COVID‐19 disease in pregnant people with COVID‐19, according to treatments received during pregnancy, and compare these data with those of nonpregnant people of reproductive age with COVID‐19.
- To assess and compare the rates of adverse maternal and neonatal outcomes in cohorts of pregnant people with COVID-19 diagnosis in the first, second, or third trimester during pregnancy and pregnant people without COVID-19.
