Introduction
In DiagnosticReport FHIR resource contains field called "serviceCategory". This filed has zero to one relationship and can take one of values presented in Codes for Diagnostic Service sections.
When the "serviceCategory" field is not presented in FHIR resource instance, those requests are handled by Default Service section.
FHIR module is using Handlers to support each type of serviceCategory sections. You can build your own handler and register for handler a particular type of DiagnosticReport.
How to Create a DiagnosticReportHandler
Requirements
- A DiagnosticReportHandler must implement the DiagnosticReportHandler interface
- A DiagnosticReportHandler may extend the AbtractHandler which contains common set of functionalities
- The DiagnosticReportHandler must be registered by Spring with a key
Examples
Laboratory Handler
- Found in the org.openmrs.module.fhir.api.diagnosticreport.handler package
- Extends org.openmrs.module.fhir.api.diagnosticreport.handler
package org.openmrs.module.fhir.api.diagnosticreport.handler;
public class LaboratoryHandler extends AbstractHandler implements DiagnosticReportHandler {
private static final String ServiceCategory = "LAB";
public LaboratoryHandler() {
super();
}
public String getServiceCategory() {
return ServiceCategory;
}
public DiagnosticReport getFHIRDiagnosticReportById(String id) {
// Implement code here
}
public List<DiagnosticReport> getFHIRDiagnosticReportBySubjectName(String name) {
// Implement code here
}
public DiagnosticReport saveFHIRDiagnosticReport(DiagnosticReport diagnosticReport) {
// Implement code here
}
public DiagnosticReport updateFHIRDiagnosticReport(DiagnosticReport diagnosticReport, String theId) {
// Implement code here
}
public void retireFHIRDiagnosticReport(String id) {
// Implement code here
}
}
Register LaboratoryHandler
Register handler in FHIR module ModuleApplicationContext.xml configuration (locate in /api/src/main/resources/moduleApplicationContext.xml).

<property name="moduleService">
