BS EN ISO 21090:2011

This standard BS EN ISO 21090:2011 Health Informatics. Harmonized data types for information interchange is classified in these ICS categories:

• 35.240.80 IT applications in health care technology

This International Standard

• provides a set of datatype definitions for representing and exchanging basic concepts that are commonly encountered in healthcare environments in support of information exchange in the healthcare environment;

• specifies a collection of healthcare-related datatypes suitable for use in a number of health-related information environments;

• declares the semantics of these datatypes using the terminology, notations and datatypes defined in ISO/IEC 11404, thus extending the set of datatypes defined in that standard;

• provides UML definitions of the same datatypes using the terminology, notation and types defined in Unified Modelling Language (UML) version 2.0;

• specifies an XML (Extensible Mark-up Language) based representation of the datatypes.

The requirements which underpin the scope reflect a mix of requirements gathered primarily from HL7 Version 3 and ISO/IEC 11404, and also from CEN/TS 14796, ISO 13606 (all parts) and past ISO work on healthcare datatypes.

This International Standard can offer a practical and useful contribution to the internal design of health information systems, but is primarily intended to be used when defining external interfaces or messages to support communication between them.
