Introduction
In order to centralize and simplify the nosocomial infection (NI) declaration process in France, the French Ministry of Health has developed a computer-based infection declaration program that has been implemented nationally in January 2012. This system allows each hospital physician running an Infection Control Unit to declare NI on a dedicated web site. Usefulness of declaring NI is evaluated by the hospital physician according to a number of predefined criteria that are reminded online in the declaration form (e.g., characteristics of the infecting microorganism, nature of the infectious site, context of acquisition of the NI, associated death, …). Additionally, declaration of colonization with multidrug-resistant bacteria is recommended.
