I am building an app for different hospitals that could be used by many doctors and many patients. The problem I am having is how to give doctors access because a doctor can be employed by more than one hospital in the system and I am also having issues on how to transfer patients registered to one hospital to another hospital without losing the patient records and which hospital the record came from.
In my app i created different verification before login. A user can be a doctor or an admin person, the doctors can be employed by more than one hospital but the admin can only work for one hospital. I gave access code to each hospital and based on the code, you get access to the hospital you want. The issue I ran into now is that, when a user logs in the current hospital is not available on home screen
