FHIR Extension Specification Released: Defining Biological Sex for Patient RDA Records

Details

This document details a technical specification for a FHIR extension definition developed for Colombia's 'Resumen Digital de Atención en Salud (RDA)' system. The `Extension: GenderIdentity` is intended for use on the Patient resource, aiming to record the biological sex of the patient or user of the health system. Structurally, it utilizes the `Coding` element and references a ValueSet called 'Colombian Gender group Codes,' ensuring standardized data retention. This specification demonstrates how FHIR can be adapted to meet local requirements within international healthcare information exchange. It provides an example of maintaining global interoperability while standardizing data according to national cultural or legal contexts. Technically, it is provided as a `StructureDefinition` named `ExtensionBiologicalGender`, requiring implementation with metadata such as ID and URL, along with system-specific codes and display names. This offers valuable insight into handling localized clinical data within the FHIR framework.
