Beginning on December 1, 2026, for three months, 200 volunteer pharmacies will automatically share data from their management systems with the National Agency for the Safety of Medicines and Health Products (ANSM). This data includes information about the stock status of medicines, the number of boxes given to patients, and orders placed with suppliers. The initiative, led by the General Directorate of Health (DGS), the Delegation for Digital Health (DNS), and the ANSM, will focus on 267 major therapeutic interest medicines (MITM), which are closely monitored due to their importance in public health. The goal is to see if this real-time data can help identify potential shortages earlier and more accurately, allowing the ANSM to adjust its strategies for managing medicine supplies. Pharmacies, whether part of a union or not, that use one of four selected pharmacy management systems—Crystal (Infosoft), id. (Pharmagest-Equasens), LEO Officine (Isipharm), and Pharmony—will be eligible to participate. Once the system is set up by the software providers, the data will be automatically sent every week. No action will be required from the pharmacy staff, as the process does not involve extracting or uploading files manually. The Federation of French Pharmaceutical Unions (FSPF) emphasizes that participation is voluntary and that pharmacies can withdraw at any time. The data collected will not be used for monitoring or penalizing pharmacies. It will also not include information that could identify individual patients, doctors, or specific prescriptions. This ensures the privacy of individuals while still providing valuable insights into medicine supply trends. The registration period for pharmacies to join the experiment is open until October 30, 2026. If more than 200 pharmacies apply, the selection process will aim to create a diverse group of participants, taking into account the type of software used, the region of the pharmacy, its size, and other relevant factors.
