Digital technology is essential in the field of health, via connected objects, the medical Internet or even telemedicine; and the info-communication practices (ways of getting information and communicating) of the actors go through digital devices. In addition, at present, the mass of activity documents to be managed in healthcare establishments and an abundant supply of documentary resources in health, available on the Internet, lead to infobesity, information pollution, and work overload. These phenomena lead to an increase in the time spent searching for relevant information and even to the burnout of healthcare professionals. A contextualization of the information communication systems through which the practices of health professionals pass therefore seems necessary so that the tools for managing, extracting and organizing knowledge can support these actors in their work.

In the field of allergies, there are many players, and the information that is useful to them is abundant and heterogeneous. This study is based on the hypothesis that a knowledge organization model, developed from existing practices, could make it possible to obtain satisfactory results when searching for information, and be integrated into the daily practices of actors by linking up with other already existing systems and tools.

Inclusion criteria:

• Professionals from the Allergy Unit (doctors, interns, paramedics, study coordinators), in total around 20-30 people.
