IE Core Health Amendment Act FHIR Specification: HAA Identifier Guide Published

Details

This document serves as an implementation guide that defines a unique identifier called 'Health Amendment Act' (HAA) within the FHIR standard, specifically tailored for use in Irish healthcare. The profile is notable for extending the Identifier element structure and imposing strict pattern constraints: HAA must be 7 characters long, contain 5 numbers, and always start and end with a letter. Technically, it achieves this by adding a custom `system` URI (`http://iehr.ai/fhir/sid/ie/haa`) and `value` field to the FHIR Identifier element, enforcing that the value must match a specific regular expression pattern (e.g., A12345A). This goes beyond mere data type definition; it sets concrete rules designed to enhance data integrity and reliability for healthcare information exchange in Ireland. For the Japanese healthcare IT industry, the standardization of region-specific identifiers and profiles within FHIR is crucial. Since various countries maintain unique data structures and code systems, combining common definitions (like HL7/SNOMED CT) with custom profiles to address local regulations is essential for system development aiming for global interoperability. This specification serves as a valuable example of how regional requirements can be realized using the flexible framework of FHIR.
