FHIR Extension for Mother's Family Name Defined: Colombia RDA Specification Release

Details

This specification was released as part of the 'Resumen Digital de Atención en Salud (RDA)' v1.0.0 by Colombia's Ministry of Health and Social Protection. Specifically, it is an extension definition named 'Extension: MothersFamilyName,' applied to the `family` element within the HumanName resource, based on FHIR standards. This extension utilizes the `family` element of the HumanName resource to record a second surname—the mother's family name—which might not be recorded in traditional medical records. This capability allows for the structured capture of detailed personal identification information, supplementing what is often missing from conventional health records. Technically, the extension adheres to FHIR standards and is provided as a structure definition with a specific URL (`https://fhir.minsalud.gov.co/rda/StructureDefinition/ExtensionMothersFamilyName`). The data type is String, and it is mandated for use on the HumanName resource's `family` element. In Japanese healthcare IT systems, managing accurate patient identifiers (IDs) is critically important. As demonstrated by this case, incorporating detailed family structure information, such as the mother's surname, into standard specifications—beyond just names—provides valuable insights for preventing misidentification and achieving comprehensive data interoperability.
