Background
Due to lack of evaluation, teratogenicity of many drugs is unknown and drug choice during pregnancy is often difficult for
health professionnals.
In France, there is no systematic follow up of women exposed to drugs and their newborns.
Aim
Results
The main aim of this study is to move towards setting up the
first French database of reimbursed drugs prescribed to
pregnant women by associating records of the drugs
prescribed and delivered during pregnancy until the outcome
of these pregnancies .
N=40355 mother-outcome of pregnancy
Methods
Population
This study concerns pregnant women who gave birth to a
baby from July 1st 2004 to June 30th 2008 in HauteGaronne and who are registered in the French Health
Insurance Service (80% of the population).
Data sources
EFEMERIS database was set up using data on prescription
drugs dispensed to pregnant women and recorded by the
Caisse Primaire d'Assurance Maladie (CPAM) of HauteGaronne and the outcomes of these pregnancies obtained
from both the Protection Maternelle et Infantile (child
health certificates) and the Centre de Diagnostic Antenatal
(medical pregnancy interruptions).

The data received from the 3 sources (CPAM, PMI, CDA)
were made anonymous with a data-processing tool provided
by the "Centre d'Etudes des Sécurités du Système
d'Information" (CESSI).

- Among the twenty most frequently prescribed drugs, around
one third of them were drugs which have not been evaluated
in
pregnant
women
(phloroglucinol,
dompéridone,
tuaminoheptane…).
- Among the drugs for which data is available, some with
proven teratogenic or fœtotoxic effects were prescribed and
delivered to pregnant patients included in the EFEMERIS
database: retinoids, NSAIDs…
Conclusion
EFEMERIS is the first French database of drugs prescribed
and dispensed during pregnancy including the outcome of
these pregnancies (birth or medical termination of
pregnancy).
This database will allow us to study drugs which are
largely prescribed in France in pregnancy and for
which no data are available yet.
