Objective

Integration of FHIR R4 into the openIMIS FHIR module

Who

Faris Ahmetasevic from University of Basel

Duration

4 months

Starting date: 23.03.2020

Ending date: 22.07.2020

Activities

Become familiar with the existing openIMIS implementation and HL7 FHIR (versions 3 and 4)
Provide a mapping from relevant fields of the most popular and relevant hospital management systems and openIMIS, with focus on the fields and attributes that are so far not yet supported
Integrate support for HL7 FHIR version 4 into openIMIS (back‐end implementation in python)
Develop a tool for the transfer of data from the openIMIS database to a FHIR database through the new developed FHIR version 4.

Discussions

Proposal to split the FHIR module per resource and version: FHIR_Claim_V4 module

Api Root

Firstly, a new directory ‘api_fhir_R4’ was created, which contained the copied files of the api_fhir module of version 3.
These files have been processed in order to create a new api root for the version 4 of the module.
After launching the backend server it is now possible to reach the api root for both versions using:
http://localhost:8000/api_fhir
/ for version 3http
_r4/
