Introduction

This implementation guide specifies the Core Principles of using the Clinical Document Architecture [1].

Scope

This guide focuses on Data Types Release 1 [2]. Meanwhile an ISO specification ISO 21090 is out, also known as Data Type Release 2. The latter is subject to another im-plementation guide that will be published when ISO data types are used.

Focus of this document: HL7 Version 3 Data Types for CDA

The following chapters of this document will focus on the description of the data types and associated material. It will highlight the essentials in four chapters, all focusing on the Norwegian situation.

  • Common aspects: explains common aspects of use of CDA and XML
  • Data types: gives an overview and detailed specification of all data types used in CDA
  • Identification schemes: explains major aspects of identification and the use in CDA
  • Use of vocabulary: explains major aspects of vocabulary use in CDA.

Background

In many (European) countries, implementation guides for the use of data types in HL7 V3 are published. They take into account country specific constraints on the data types.
