Company Description
More than 3,000 heads of business are currently involved in our Group, Groupement Les Mousquetaires, bound by a sense of initiative, their conviction, their attachment to their local area and their desire to live “independently in interdependence.”
Each point of sale is managed by an independent business owner who is a stakeholder in the local socio-economic fabric. This unique organization set up both in France as well as beyond our borders and which we call associated trade, contributes significantly to the success of the Mousquetaires.
The business owners assume full responsibility for managing their point of sale. At the same time, they are in charge of the co-management of the Group. In concrete terms, a member dedicates two days per week to the management of a Group subsidiary. This operational supervision covers trade, supply, production units, logistics…
The entrepreneurs can also be shareholders of the Group, thus formally becoming “partner members” of Société les Mousquetaires.

Company Description
In a world with an aging population, an increase in chronic diseases and complex migratory flows, the care model based on “episodes” is no longer applicable. It is fundamental to move towards a complete and effective continuum of care paradigm, with the ablilty to support patients, caregivers, care and social institutions in managing the complexity of the collaboration now required to deliver patient care.
In this new approach, the role of Information Technology is essential: it enables an effective and efficient flow of information across multiple settings and stakeholders to ensure the best outcomes in each phase: from prevention to early detection, from diagnosis to treatment, from rehabilitation to follow-up and end-of-life. Patients, caregivers, health professionals are always aware of the overall pathway and they are able to contribute effectively to the final outcome.
Dedalus offers multiple and diverse solutions for each phase of the continuum of care, ensuring the integration of every single care setting, institution and system in the process.
