Doctor-patient communication is currently being carried out in hospitals, and in the process of communication I have found that most patients do not know enough about the disease and have too little medical knowledge. Either they don’t know anything about it or they read something on the internet and think it is holy writ, neither of which I think is right. Patients and their families should learn to gain medical knowledge at the doctor, which means learning to communicate with the doctor. 1) Communicate with the doctor when the doctor is a little free. 2) Do some homework beforehand to learn the basics of your disease. 3) Be in a stable state of mind. 4) Of course you need to find a better doctor to communicate with. The purpose of the communication is for you to understand the condition, and the diagnosis, what tests are needed, how to treat it, and what the risks are.
