I don't think we want one common data base but rather run it such that we will all link indivually to one common server but on the server have different domains for each physician. I am not sure if this is the proper terminology.
I agree with David. What you describe is the most complex setup I have heard in the eight years I have been on here. There is really no way to combine databases of separate practices whether on a server with one domain or seven domains. If you have a separate tax ID#, then you have a separate practice, and the databases will not work together. I don't even know how you would do it with an EMR. I am not understanding how having separate practices link to one server will help share data.
You would be better off incorporating under one tax ID#.
