Epic software has really made sharing patient information streamline not only within a specific large integrated hospital system such as Mayo Clinic, it also allows for transferring between other medical facilities which also has the system.

If I’m understanding your question correctly, while the information can be transferred between medical institutions with your permission, it may not mean you can be diagnosed in one facility and be treated in another. Each institution remains independent. Also there are some medical institutions which still may require their own testing.

However, it’s really beneficial to have these records so easily shared. A personal example: Last October I had a series of tests run at Mayo. I needed to have a followup at my home clinic in January for the same condition. Both my Mayo doctor and my local doctor were able to compare the results of these tests instantly via computer. I didn’t have to request copies to be faxed to either doctor.

In my case, my local doctor who is my oncologist, does take directions from my bone marrow transplant doctor at Mayo. They are working collaboratively even though they are in different medical establishments. Mayo, once there has been a diagnosis and treatment plan, will often transfer care back to the patient’s local clinic to make it easier for the patient…again, that immediate access to patient records is so convenient.

I found some information for you regarding the hospitals in the which use Epic Software system. It’s a global system so there are some countries outside the US which use Epic.
