The National Infectious Disease Information Report Management Guide (Version 20 16) clearly stipulates that medical institutions at all levels have realized the electronization of infectious disease report cards, which is in line with the Electronic Signature Law of People's Republic of China (PRC). Electronic signatures and timestamps are regarded as having the same legal effect as the paper version, so backup is needed, and the backup and storage time is at least the same as that of paper infectious disease report cards. Those who do not meet the requirements for the time being must be printed into a standard paper card, signed by the first-time doctor and kept for the record. For medical institutions that realize direct data exchange, the backup time of electronic exchange documents (converted XML files) should be at least the same as that of paper infectious disease report cards. First-time doctors can automatically extract electronic infectious disease report cards that meet the standards of exchanging documents through electronic medical records and electronic health records after discovering infectious disease patients and suspected patients in the process of diagnosis and treatment.
