I tried to make an Electronic Medical Records System for my father, who is a doctor. It started small and got rolling until it took up more of my time than I am willing to admit, then, in the final stages, the government released a stimulus package for doctors who use a very specific set of EMR systems, of which mine was not included. The costs and time required to get in to that set were unrealistic. I abandoned the project.
I'm working on uploading that project here in a manner that showcases all of the features that it has, because it's quite a nice system. Unfortunately, I don't think it will go in to use.
I'll update this page when I manage to get the project uploaded and opened up so people can see the internals.
