To reform the unit of preventive medicine in Orleans metropole, the Director of the Administration decided to co-sign an agreement to optimize the organization of a common preventive medicine service: we made a deliberation model to permit for others towns which wanted to join us. The cost evaluated to reach the service was the cost for medical examination, regardless of the professional which included staff costs and operating costs (social benefits, costs of supplies and materials, training costs). A statement of the tasks performed for the beneficiary community was kept daily by the SMP. A strong will of the Metropolis and municipalities is to develop a synergy around health and safety at work. A joint Metropolis of Orleans, an organization chart since 1/2/2016 integrates the preventive medicine service within a Quality of Life at Work service: a multi-disciplinary service composed of prevention specialists, social workers, responsible for social action and SMP, a Department of Preventive Medicine was developed and itself multidisciplinary in accordance with the law of July 20, 2011: including doctors, nurses, psychologists, sophrologist, and a dietician. A new and active network of health is now operant with specialist correspondents. An audit is programmed in April 2018 to assess the efficacy of this network.
