The Cohort Definition module allows you to define the scope of the analysis you want to perform:

  • The Market / product including the choice of WHO ATC class and / or product code and / or brand…

  • Co-treatments with the possibility of including or excluding patients who have received, in addition, products belonging to selected WHO ATC classes

  • The Demographic Profile using patient age and gender variables

  • The Period including the choice of the regularity of pharmacy visits* and the selection of the analysis period (closed or open cohort)

* The regularity of the visits corresponds to the maximum time desired between 2 visits to the pharmacy (whatever the product dispensed) . Beyond this period, patients will be excluded from the analysis

Ex: if the regularity of visits is set at 3 months, each patient must return to the pharmacy at least every 3 months over the entire analysis period in order to be included.
