Microfrontend UI for FHIR metadata CRUD operations

Abstract

FHIR is an emerging standard for healthcare interoperability. OpenMRS has been an early adopter of the FHIR standard, but there is still more we could add to the FHIR module. This project involves creating a simple and effective User Interface (UI) on top of the Microfrontend / SPA framework to make CRUD (Create, Read, Update and Delete) operations easier for FHIR metadata tables.

In our FHIR module, we have 3 FHIR metadata tables (for now; we could eventually have more like these). These tables are pretty straight-forward mappings between some piece of FHIR-specific data and a piece of OpenMRS data. The three tables are:

• fhir_concept_source : maps between an OpenMRS ConceptSource and the URL for the corresponding FHIR CodeSystem . This sounds complicated, but it’s really just for mapping things like: LOINC -> http://loinc.org, SNOMED CT -> http://snomed.info/sct. The names come from the ConceptSource.name field.
• fhir_encounter_class_map : maps between OpenMRS locations and this FHIR valueset.
• fhir_observation_category_map : maps between an OpenMRS ConceptClass and this FHIR valueset.

So the project would involve creating a Microfrontend UI which would use REST to do CRUD operations on the above tables.

Project Champions

• Ian Bacher

Skills Needed

• Familiarity with Java and Javascript
• Familiarity with React
• Good understanding of REST
• HTML/CSS

Objectives

• Create appropriate REST web-services to do the CRUD tasks for the FHIR metadata tables.
• Create the frontend to communicate with these REST web services.

Extra Credit

• Extend the frontend to be used for other FHIR tasks like getting available code system names, etc.
