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 3
http://localhost:8000/api_fhir_R4/ for version 4
Mapping
Overview Table
FHIR R4 Resource | OpenIMIS database tables | notes | mapping status |
|---|---|---|---|
Claim |
| Request properties are mapped to Claim | mostly mapped has to be updated with the new resources |
ClaimResponse |
| Response properties are mapped to Claim | mostly mapped has to be updated with the new resources |
Coverage | tblPolicy | mostly mapped | |
Patient | tblInsuree | mostly mapped | |
Practitioner | tblClaimAdmin | used to represent base fields of Claim Administrator (without relation with health facility- FHIR R4 Location) | mapped |
PractitionerRole | tblClaimAdmin | used to represent a relation between base ClaimAdmin (FHIR R4 Partitioner) and Health facility (FHIR R4 Location) | mapped |
Location |
| FHIR R4 location.mode field is used to switch between mapping from tblHF and tblLocations | mostly mapped |
CoverageEligibilityRequest | CoverageEligibilityRequest | mostly mapped | |
CoverageEligibilityResponse | CoverageEligibilityResponse | mostly mapped | |
CommunicationRequest | tblFeedback | mapped | |
Condition | tblICDCodes | mapped | |
Medication | tblItems | mapped | |
