In the light of recent experiences and anticipating an increase in sim
ilar requests in the future, it seemed very interesting to a drug safe
ty executives' group from the pharmaceutical industry to propose guide
lines for the set-up and followup of pharmacoepidemiological studies r
equested by Health Authorities for the assessment of drug risk. The sc
ope of these guidelines is to establish the responsibility of the team
s and structures involved in the study, to define the necessary stages
set-up, and to determine the rules in order to ensure its smooth runn
ing from the drafting of the protocole to the final use of the data.
