web github.com Jens Kristian built c3po-initiative/1177 , a read-only HAPI FHIR R4 proxy that fronts three Swedish 1177 services and exposes them as standard FHIR. The proxy authenticates against the Inera QA environment using HTTP Basic (personnummer + portal password), performs a SAML/Shibboleth login dance against the shared Inera IDP for each upstream SP, and joins the responses into a single FHIR API per authenticated patient. It maps journalen (journal records, HTML fragments inside JSON envelopes) to DocumentReference , bokadetider (appointment booking) to Appointment , and e-tjanster (patient inbox) to Communication / DocumentReference . The whole thing was assembled in under five hours of AI-assisted coding, and Jens Kristian's takeaway was that there are no technical limitations to building a FHIR facade for 1177 - it is entirely a governance question. The repo follows the pattern previously established for the Danish Dhroxy project.

web www.health-samurai.io Nikolai demonstrated Termbox , a FHIR terminology server from Health Samurai. The demo walked through browsing code systems and value sets, executing terminology operations (with $lookup available today and $translate plus closure support in active development), and loading terminologies from multiple sources - FHIR packages, NPM packages from the registry, atom syndication feeds, or a single config file declaring all dependencies. A particularly useful view shows the full dependency graph for a value set, which helps diagnose problems when a specific dependency fails to resolve.

web github.com Michael kicked off fhir-syndication-ig ( published ), a FHIR Implementation Guide specifying the Atom-based terminology syndication feed format originally developed for Australia's National Clinical Terminology Service (NCTS). The IG documents the feed and entry shape, field semantics, cross-field constraints, the controlled vocabularies used in <category> , and three extension namespaces (NCTS ASF, SNOMED CT, and Ontoserver). It enables terminology servers to advertise the code systems, value sets, concept maps, and packages they publish - along with version, publication date, and download links - so consumer servers can discover and either automatically ingest or fetch the content on demand. SNOMED International already publishes a feed of their RF2 content using this format, and any Ontoserver instance can publish a feed of what it contains. Nikolai Ryzhikov ( Health Samurai ) also contributed, with input from Mark Czotter and Gábor Nagy (both IQVIA , Hungary).

web www.who.int Vadim's day job at the hackathon was running the Terminology track itself, so the mapping work ran in the background on his laptop while he facilitated: a team of Claude agents chewed through 2000 SNOMED CT procedure codes during the day without him touching the keyboard for most of it. The full task is around 60,000 SNOMED CT procedure codes to the ~15,000 codes in ICHI (WHO's International Classification of Health Interventions), driven by a clinical-information problem: if no mapping exists, clinicians end up entering ICHI directly at the point of capture and lose the clinical-level detail SNOMED would have preserved. The setup is a while true shell loop running Claude agents in batches of 50, each emitting FHIR ConceptMap entries with source, relationship (narrower/wider/equivalent/related), target, and the agent's rationale - all going to a Google Sheet for human modellers to review before any production use.

web github.com This track explores whether AI agents can enable patient access to health data portals that do not natively support FHIR. The approach is inspired by the Danish Dhroxy project, developed as part of the c3po initiative , which uses AI agents to provide FHIR-based access to existing patient portals.
web www.kanta.fi Mikael Rinnetmaki is interested in exploring whether this approach could be replicated in Finland with the Kanta patient portal .

web github.com Tip: Before feeding a HAR file to an AI tool, scrub or replace real patient values (names, personnummer, dates of birth) with synthetic equivalents — the structure and field names are what matter for mapping, not the actual data. har-sanitizer (Cloudflare) can help automate this step. Alternatively, chrome-devtools-mcp lets an AI agent connect directly to Chrome DevTools and observe network traffic in real time, skipping the manual export step entirely.
