I think this is not a problem. After all, the project will work remotely and you will communicate with doctors using a smartphone, the most important thing is to choose a specialist and that's it.
We can choose doctors only from our city and country, or from other cities or countries, will we also be able to choose doctors?
You can choose doctors from absolutely any country, the main thing is that the language barrier does not interfere with your communication. It will still cost on the blockchain, payment will also be as I understood it with platform tokens, and without a difference the location of the doctor and the patient.
to communicate with a remote doctor,as I understand it, you need the doctor to see all the information about you, the patient,
but in order for your information to be included in the project, the medical institution of your country must first provide it to the project-and this may be difficult for some countries
Why do you think so? An experienced doctor needs only your analyzes and the symptoms you have, you can take the analyzes anywhere, and you can join up with your video connection.
