MedX Registry
A community-maintained catalogue of medical devices, health software, organizations, facility lists, and LOINC-coded observations. Built for interoperability with FHIR R4 and designed for low-resource health systems.
What's in the registry?
The registry stores six resource types, all modelled on FHIR R4:
Devices
DeviceDefinition
Lab analysers, POC devices, medical equipment with connection and parameter mappings.
Software
DeviceDefinition (app)
EMR, LIS, HMIS, middleware and FHIR server applications with protocol metadata.
Organizations
Organization
Manufacturers, publishers, health authorities and service providers.
Collections
List
Master facility lists, device catalogues, LOINC subsets and protocol compilations.
Locations
Location
Health facilities cross-referenced with MFL IDs and DHIS2 UIDs.
Observations
ObservationDefinition
LOINC-coded observation definitions with reference ranges and device linkages.
Access model
The registry exposes two access tiers:
- Public read — anyone can query approved records without authentication.
- Authenticated write / admin — submitting proposals, approving records, and managing private org-scoped data requires a MedX account with the appropriate SMART on FHIR scopes.
Data access uses the Registry Client, a typed SDK for JavaScript/TypeScript. There is no GraphQL endpoint. REST-style admin endpoints are exposed through the same client under an admin namespace and are gated by server-side scope validation.
