Implementing a National Data Viewer Project using FHIR
summary
Estonia’s central EHR holds over 100 million CDA documents, and a web Data Viewer is built that queries the national HIS, applies a CDA-to-FHIR mapping engine and returns FHIR resources with on-the-fly conversion for interactive views. It deduplicates results, copes with legacy CDA template versions and shifting terminologies (needed concept maps to SNOMED), presents timelines, labs and coded diagnosis summaries, scales in production, and receives notably positive clinician feedback while currently serving as the single front-end user.
