1.3.1
FHIR R4 US Core Implementation Guide - 5.0.1 - STU5 Release US

Sample Usage

This section focuses on samples depicting how to use this package to implement FHIR related integrations

Prerequisites

  1. Install Ballerina 2201.6.0 or later

1. Parse JSON FHIR resource to FHIR resource model

Sample below is using the Patient resource in health.fhir.r4.uscore501 package.

Copy
import ballerina/log;
import ballerinax/health.fhir.r4.uscore501;
import ballerinax/health.fhir.r4.parser;

public function main() {
    json patientPayload = {
        "resourceType": "Patient",
        "id": "example-patient",
        "text": {
            "status": "generated",
            "div": "<div xmlns=\"http://www.w3.org/1999/xhtml\">John Doe</div>"
        },
        "identifier": [
            {
                "system": "http://example.com/patient-ids",
                "value": "12345"
            }
        ],
        "extension": [
            {
                "url": "http://hl7.org/fhir/us/core/StructureDefinition/us-core-race",
                "valueCodeableConcept": {
                    "coding": [
                        {
                            "system": "http://hl7.org/fhir/v3/Race",
                            "code": "2106-3",
                            "display": "White"
                        }
                    ]
                }
            }
        ],
        "name": [
            {
                "use": "official",
                "family": "Doe",
                "given": [
                    "John"
                ]
            }
        ],
        "gender": "male",
        "birthDate": "2000-01-01"
    };

    do {
        anydata parsedResult = check parser:parse(patientPayload, uscore501:USCorePatientProfile);
        uscore501:USCorePatientProfile patientModel = check parsedResult.ensureType();
        log:printInfo(string `Patient name : ${patientModel.name[0].toString()}`);
    } on fail error parseError {
    	log:printError(string `Error occurred while parsing : ${parseError.message()}`, parseError);
    }
}

2. Creating FHIR Resource models and serializing to JSON wire formats

Copy
import ballerina/log;
import ballerina/time;
import ballerinax/health.fhir.r4.uscore501;
import ballerinax/health.fhir.r4;

public function main() {
    uscore501:USCorePatientProfile patient = {
        meta: {
            lastUpdated: time:utcToString(time:utcNow()),
            profile: [uscore501:PROFILE_BASE_USCOREPATIENTPROFILE]
        },
        active: true,
        name: [
            {
                family: "Doe",
                given: ["Jhon"],
                use: uscore501:CODE_USE_OFFICIAL,
                prefix: ["Mr"]
            }
        ],
        address: [
            {
                line: ["652 S. Lantern Dr."],
                city: "New York",
                country: "United States",
                postalCode: "10022",
                'type: uscore501:CODE_TYPE_PHYSICAL,
                use: uscore501:CODE_USE_HOME
            }
        ],
        identifier: [],
        gender: uscore501:CODE_GENDER_MALE
    };
    r4:FHIRResourceEntity fhirEntity = new(patient);
    // Serialize FHIR resource record to Json payload
    json|r4:FHIRSerializerError jsonResult = fhirEntity.toJson();
    if jsonResult is json {
        log:printInfo(string `Patient resource JSON payload : ${jsonResult.toJsonString()}`);
    } else {
        log:printError(string `Error occurred while serializing to JSON payload : ${jsonResult.message()}`, jsonResult);
    }
}
