FHIR Services API

The three FHIR service classes live in node-server/src/; methods return JSON-serialisable objects.

class FHIRConditionService (fhirConditionService.ts)

Reads icd.diagnoses directly (through the shared pool in db.ts); it does not depend on another service instance.

async createCondition(icdCode, patientId, opts = {})

Builds a FHIR R4 Condition from an ICD-10-CM code (system http://hl7.org/fhir/sid/icd-10-cm); opts covers clinical / verification status, category, severity, dates and notes. Backs Path A of query_fhir_condition.

async createConditionFromSearch(keyword, patientId, opts = {})

Searches an ICD code by keyword first, then builds the Condition; applies only clinical / verification status and severity. Backs Path B.

validateCondition(condition)

Basic structural validation, returns {valid, errors, warnings}. Backs validate_fhir_condition.

class FHIRMedicationService (fhirMedicationService.ts)

async createMedication(licenseId, resourceType = "Medication")

Builds a Medication or MedicationKnowledge from a TFDA license (CodeSystem https://mcp.fda.gov.tw/fhir/CodeSystem/tfda-license-id), using normalised TFDA data only.

async createMedicationFromSearch(keyword, resourceType = "Medication")

Searches the drug first, then builds the resource.

validateMedication(medication)

Basic structural validation, returns {valid, resource_type, errors}. Backs validate_fhir_medication.

class FHIRIGService (fhirIgService.ts)

The multi-IG profile / terminology / validation / authoring service behind every fhir_* tool. Each method returns a JSON string in the shared envelope {ok, data, warnings, provenance, error?}; package-resolution rules (provenance.resolved_by, NO_DEFAULT_IG, |version) and per-tool parameters are in FHIR IG Tools.
