Transforming OpenMRS Patient to FHIR Patient in json

craiglorck · October 24, 2018, 6:05am

Greetings!

Our team has created a FHIR API Server based on HAPI-FHIR; it is now up and waiting to be tested. We would like to convert an OpenMRS Patient to FHIR Patient and vice versa if this is possible. The idea is, well, our FHIR API Server will serve as the Interoperability layer of our system.

How can we do this? We did find this tutorial https://fhir-drills.github.io/fhir-api.html , but we are having problems with the dependencies leading to the UI of our OpenMRS unable to display.

Is this, in any way, related to the work that @SolDevelo is doing for sync 2? https://wiki.openmrs.org/display/projects/FHIR+Resource+List+for+Sync

@dkayiwa yes, we use and improve code responsible for converting OpenMRS Patient and FHIR Patient. @craiglorck you can find this conversion in FHIR module here

public class FHIRPatientUtil {


	public static Patient generatePatient(org.openmrs.Patient omrsPatient) {


		Patient patient = new Patient();


		BaseOpenMRSDataUtil.setBaseExtensionFields(patient, omrsPatient);


		//Set patient id to fhir patient
		IdType uuid = new IdType();
		uuid.setValue(omrsPatient.getUuid());
		patient.setId(uuid);

			ContactPoint telecom = new ContactPoint();
			telecom.setSystem(ContactPoint.ContactPointSystem.PHONE).setValue(omrsPatient.getAttribute(
					FHIRUtils.PATIENT_PHONE_NUMBER_ATTRIBUTE).getValue());
			dts.add(telecom);

		patient.setTelecom(dts);
		FHIRUtils.validate(patient);
		return patient;
	}

		boolean preferedPresent = false, givennamePresent = false, familynamePresent = false, doCheckName = true;


		org.openmrs.Patient omrsPatient = new org.openmrs.Patient(); // add eror handli


		BaseOpenMRSDataUtil.readBaseExtensionFields(omrsPatient, patient);


		if (patient.getId() != null) {
			omrsPatient.setUuid(extractUuid(patient.getId()));
		}

All supported entities are listed on Sync2 wiki page with its FHIR Maturity Level provided https://wiki.openmrs.org/display/projects/FHIR+Resource+List+for+Sync
