- Urgens Codex is an application reserved for hospital staff sharing certain procedures and data. The application alone is useless, it is necessary to have the module codes to add in the application to be able to use it. _ - To be able to use it, you can contact the department heads or executives of your department, or use the links available at http://lagny77.free.fr under the Urgens Codex section (the access codes will be provided to you by the same people or your colleagues). You can also contact me if needed. _ - Dr P. Mignard, P.H. Emergency department / SMUR, GHEF - Marne-la-Vallée site (77) -
