Introduction

The CZ Base and Core implementation guide is based on FHIR version R4. It defines the minimum rules for interoperability and national customization of FHIR resources, which is applied when creating national profiles for specific use cases. The establishment of standards to support interoperability and their implementation in information systems creates a common basis for the interoperable exchange of health data.

In this implementation guide, you will find the rules for creating national profiles, the use of identifiers and basic information components.

Scope

This document presents Czech use concepts defined via FHIR processable artefacts; these are collaborative outputs with agreed approaches to varied kinds of healthcare related information based on the core FHIR R4 specification.

Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (hl7.fhir.cz.core.r4) and R4B (hl7.fhir.cz.core.r4b) are available.
