What are the classifications and standards of hospital information system standardization?

The standardization of hospital information system mainly involves the following categories and standards:

1. Data standardization: including format standard, coding standard and data exchange standard of medical data. Among them, the commonly used medical data standards include HL7 (Health Grade 7) standard and SNO MED CT (Systematic Naming of Medical Clinical Terms) coding standard.

2. Security and privacy standards: including medical information security management, personal privacy protection and other standards. For example, ISO/IEC 2700 1 (Information Security Management System), HIPAA (American Health Insurance Portability and Accountability Act) and so on.

3. Electronic medical record standards: including the content, format and structure standards of electronic medical records. For example, the domestic electronic medical record basic data set and the international CDA (Clinical Document Architecture) standard.

4. Medical imaging standards: including standards for the collection, transmission, storage and display of medical imaging data. Commonly used medical imaging standards include DICOM (Digital Imaging and Communication in Medicine) standard and PACS (Image Archiving and Communication System) standard.

5. Clinical pathway standards: including medical procedures, treatment plans and other standards. For example, the domestic "Clinical Pathway Management Measures" and so on.

6. Drug management standards: including drug identification, drug classification, drug use standards and other standards. For example, domestic drug information, international RxNorm (standardization of drug terms) and so on.

The above are just some common classifications and standards of hospital information system standardization, which actually involve a wider range. In the implementation of hospital information system, it is necessary to select appropriate application standards according to actual needs and relevant laws and regulations.
