For a system which interacts with Germany's divers structure of health authorities. Last time I counted there were 374 municipal health authorities, all of them have to be integrated. Also the laboratories and doctors. In addition they set up two calling centers (a technical hotline and a health hotline) and did multiple audits for security and for epidimological sense. And then all of it, frontend and backend, is open source. For a government project that is cheap! (25cent per citizen) Edit: source for the 374 is the table on https://de.m.wikipedia.org/wiki/Gesundheitsamt https://de.m.wikipedia.org/wiki/Gesundheitsamt
