As part of our quality policy, OpenHealth allows customers who wish to break down very finely the method of calculating sales volume and product value on a sample of products of their market.

Our clients wishing to replace their current panelist with OpenHealth sometimes ask us for such studies in order to provide a documented understanding of possible data discrepancies with their former panelist.

What are the criteria that determine the quality of the data of a panelist like Openhealth and to be taken into account in such a study?

The criteria are obviously numerous, and here is a non-exhaustive list of points of attention at OpenHealth:

  • We distinguish the date of interception of the first sale and the date of registration in the database. Indeed, the sales of a product must be calculated in relation to the date of observation of the first sale and not on the date of registration in the database.
  • Price calculation is also a key variable. Indeed, our prices are applied to the transaction (= price actually displayed on the receipt), to reflect the market prices in euro, and not from reference prices
  • The rate of pharmacy cover . OpenHealth communicates transparently to its customers or prospects

Input data, to be given by the customer:

  • List of GTINs

Output data, provided by OpenHealth:

  • Turnover
  • Sales Volume
  • Date of first intercepted sale
  • Date of registration in the database
  • List of GTINs with their Technical Codes

ANNEX 1:
A product sometimes has several GTINs and Openhealth thus uses a technical code called "Grouping code" in order to make the link between the different codes. This, in the following cases:

  • If a product is made in France in 2 different factories, there may be 2 separate GTINs for traceability aspects, even though it is the same product.
  • If a product experiences a "minor" modification to its product sheet (example: the cap changes color), this will generate the creation of a new GTIN even though it is the same product.

Conversely, it is necessary to have another code serving as a "separator", in order to distinguish the 2 products and follow the evolution of sales over time, in in this case, the Technical Code is an "explosion code"

  • For example in the case of reuse of the same GTIN over time by a firm for a new product when the old one is no longer marketed.
