Intersection of FHIR Resource Definitions: cdl-ext-is-emergency Common Specification

Intersection of cdl-ext-is-emergency and cdl-ext-is-emergency

Summary

This document describes the structure for a specific FHIR resource that must conform to two identical extensions (cdl-ext-is-emergency). This demonstrates data consistency and rigorous definition in healthcare information exchange.

Details

This article is a technical reference detailing the structural intersection of FHIR resource definitions. Specifically, it describes the structure when a resource extended by 'cdl-ext-is-emergency' must satisfy two identical constraints (https://interop.esante.gouv.fr/ig/fhir/cdl/StructureDefinition/cdl-ext-is-emergency). The definition specifies detailed constraints regarding FHIR element requirements and extension field handling (e.g., all FHIR elements must have @value or children; `Must have either extensions or value[x], not both`). This aims to ensure data integrity in healthcare data exchange and provides strict specifications for handling emergency flags within a specific clinical domain (CdL). From a technical perspective, this is crucial for understanding how multiple constraints and extensions interact during FHIR-based system interoperability.
