1. Study identification
EU PAS Register NumberEUPAS5356
Official titleVeinotonics in pregnancy: a comparative study in the EFEMERIS database
Study title acronym
Study typeObservational study
Brief description of the studyThere are few published data about possible effects of veinotonics in pregnant women. However, many French women use these medications during their pregnancy. The aim of the study is to investigate potential adverse drug reactions of veinotonics in pregnancy. The study is conducted in EFEMERIS, a database including prescribed and dispensed reimbursed drugs during pregnancy (data from Caisse Primaire d'Assurance Maladie of Haute-Garonne) and outcomes (data from Maternal and Infant Protection Service and from Antenatal diagnosis Centre). Women who delivered from July 1st 2004 to December 31th 2007 in Haute-Garonne (time period when veinotonics were still reimbursed) and were registered in the French Health Insurance Service have been included. We compare pregnancy outcomes and newborn health between women exposed to veinotonics during pregnancy and unexposed women.

12. Main objective(s)
What is the main objective of the study?
The main objective is to investigate potential adverse drug reactions of veinotonics in pregnancy.
Are there primary outcomes?Yes
all-cause pregnancy loss, preterm birth, small for gestational age, neonatal pathology, congenital malformation
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Not applicable/no follow-up
15. Data analysis plan
Please provide a brief summary of the analysis method
We compare pregnancy outcomes and newborn health between women exposed to veinotonics during pregnancy and unexposed women. Multivariable cox proportional hazards regressions are used to estimate hazard ratios with 95 % CIs, comparing the hazard rates of pregnancy termination and preterm birth between exposed and unexposed women. Multivariable conditional logistic regressions with 95 % CIs are used to analyze the effect of exposure to veinotonics on the risks of small for gestational age, neonatal pathology, and congenital malformation.
