FHIR Extension Specification: Definition of MothersFamilyName for Recording Mother's Surname

Details

This document provides the detailed specification definition for the FHIR extension resource, 'Extension: MothersFamilyName', used within Colombia's 'Resumen Digital de Atención en Salud (RDA)'. This extension is specifically designed to record a person's second family name—the mother's surname—within the HumanName element. Technically, the extension is built upon the FHIR standard and utilizes core extension structures such as `Extension.id` and `Extension.url`. By implementing this specification, it becomes possible to accurately exchange detailed information regarding family structure that was previously not covered by conventional name fields. This represents a critical step toward improving the comprehensiveness and accuracy of medical data in regions where documenting maternal lineage is particularly important for healthcare records.
