Application intended for the doctors of the GHU Mondor of Public Assistance - Hospitals of Paris (APHP). This application contains the most frequently used reception information, directory and protocols. It will eventually replace paper documents that are often incomplete and quickly obsolete, especially for newcomers and especially the youngest (interns) who change hospital placements every 6 months. The content of this application will be regularly updated and enriched with new treatment protocols validated by the medical community of our hospital group. We want to make it a practical and essential tool. This project is part of a desire of the APHP to build tools using the modern and essential means of communication that are the applications usable via Smartphones.
