GB/T 21715.3-2025 Health informatics—Patient healthcard data—Part 3:Limited clinical data

Scope

This document describes and defines the limited clinical data objects used or referenced by the patient-held health data cards, using UML, plain text, and ASN.1.
This document specifies the basic structure of the data contained in the data object "Limited Clinical Data", but does not stipulate or provide a mandatory set of data stored in the device. For example, the data objects in Limited Clinical Data contain data used for emergency services, but do not include all the information required for emergency care.
The detailed functions and mechanisms of the following services are not within the scope of this document (the structure of these services allows the use of appropriate data objects specified elsewhere):
—— Encoding of free-text data;
—— Security functions and related services specified by the data card user for specific applications, such as confidentiality protection, data integrity protection, and verification of individuals and devices related to these functions;
—— Access control services dependent on the security of certain data cards, such as microprocessor cards;
—— Initialization and issuance processes (indicating the start of the personal data card's operating cycle and preparing the data card to transmit data compliant with this document in subsequent communications).
The following content is beyond the scope of this document:
—— Physical or logical solutions for the actual functions of specific types of data cards;
—— Methods of processing messages between two system interfaces;
—— The form in which data is used outside the data card, and the ways in which such data can be clearly expressed in the data card or elsewhere.
