This will never work.
Practicing medicine is a highly regulated field. At least in my country. If you practice medicine without a license as a company, or a doctor, you are in big trouble. I don´t know what country you operate from, but that must be true for all countries. A Swedish doctor treating a Swedish citizen in another country must be licensed and work through a credited company. So first you must get permission to practice medicine in every country that you want to operate in. That means you must follow every rule of how to store patient medical records (trust me, you will never ever get permission to store patient journals on a blockchain), you must follow every complicated tax rule there is for medical practice in every country. You must have insurance for every doctor you have. Who is to blame if the doctor makes some error? You? If you somehow succeed in doing all of that (and that is going to cost you a fortune) then you must do advertisement in every country to get patients. Then you must convince good doctors to come and work for you. No doctor I know of would be willing to risk loosing their medical license working for some company that did not follow every rule and regulation. If you succeeded in doing all that, you still have to get enough costumers to make you business profitable - and I do not see the market for that. And even if I am wrong and there is a huge market for this and you manage to pull of everything I described and more then still there is no need for a blockchain. You can host all of that on a local server like every other medical and telemedical company.
The blockchain is NOT the answer to all out prayer. It does not solve everything. The blockchain provides a censorship resistant network and some anonymity. That is it. If you know of anything else that a blockchain provides, please tell me because I can´t see it. And your business does not need any of that. That is, if this is not some “get rich fast scam token”. If that is your business plan, then maybe you will succeed. I doubt it, but maybe.
