According to the overseas version of People's Daily, recently, Huang Mingjun, an academician of the Singapore Academy of Sciences, said in an interview that many patients have medical data in different hospitals. In the past, data between different hospitals could not be shared. Although electronic medical records are becoming popular, due to the lack of artificial intelligence integration, electronic medical records and health records may not be patient-centric, but exist in a fragmented manner and stored in different databases. What the blockchain is to do is to provide a very comprehensive and complete data, and to provide personalized medicine centered on the patient, so that patients can decide to whom their information is shared. Once you have such a comprehensive database, the quality of medical care can be improved.
