In my point of view, I also agree with you all, in case of data analysis and data sharing. However, in the case of a user, my friend who is a clinician told me that the use of ICD10 makes her work waste time because the program to search ICD10 is not user-friendly at all. It is very difficult to search for ICD10 related to diseases or symptoms. Moreover, it is not help to treat patients. So if there are other better choices, she ready to use them instead.
