The standardization of hospital information system mainly involves the following classifications and standards:
1. Data standardization: including medical data format standards, coding standards, data exchange standards, etc. Among them, commonly used medical data standards include HL7 (Health Level Seven) standard, SNOMED CT (Systematized Nomenclature of Medicine Clinical) standard, and the standard of data exchange. Among them, the commonly used medical data standards include HL7 (Health Level Seven) standards, SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) coding standards and so on.
2. Security and privacy standards: These include standards for the secure management of medical information and the protection of personal privacy. For example, ISO/IEC 27001 (information security management system), HIPAA (U.S. Health Insurance Portability and Accountability Act), etc.
3.
3. Electronic medical record standards: Including the content, format, structure and other aspects of the electronic medical record standards. For example, the domestic "basic data set of electronic medical records", the international CDA (Clinical Document Architecture) standards, etc.
4.
4. Medical imaging standards: Including medical imaging data acquisition, transmission, storage, display and other aspects of the standard. Commonly used medical imaging standards include DICOM (Digital Imaging and Communications in Medicine) standards, PACS (Picture Archiving and Communication System) standards, etc.
5.
5. Clinical pathway standards: including medical procedures, treatment programs and other aspects of the standard. For example, the domestic "Clinical Path Management Measures" and so on.
6. Drug management standards: including drug labeling, drug classification, medication standards and other standards. For example, the domestic "Drug Information", the international RxNorm (standardization of drug terminology).
The above are just some of the common classifications and standards of hospital information system standardization, in fact, the scope is much wider. When implementing a hospital information system, you need to choose the right standard to apply based on actual needs and relevant regulations.
