Topic: OHDSI (OMOP) and HL7 International (FHIR) alignment

As noticed in the #FAIR stream too, there was a partnership between the OHDSI (OMOP) community and HL7 International announced: https://www.ohdsi.org/ohdsi-hl7-collaboration/

I only see Charles Jaffe and George Hripcsak in that article. Does anyone know who to reach out to for more information?
From the few words in the announcement it seems like a joint data model between FHIR and OMOP will be developed. Anyone details on the approach?

Over the years there have been MANY mappings between the two models, but, as indicated by the new ones being developed, they have reusable to a very limited extend:

All the ones listed here: https://www.ohdsi.org/web/wiki/doku.php?id=projects:workgroups:mappings_between_ohdsi_cdm_and_fhir, including:
- Georgia Tech's http://omoponfhir.org/
- CDMH project: http://build.fhir.org/ig/HL7/cdmh/profiles.html#omop-to-fhir-mappings
MIRACUM: https://www.devdays.com/wp-content/uploads/2019/12/Sohrab-Hejazi-Map-FHIR-to-OMOP-_-DevDays-2019-Amsterdam.pdf
Google: https://github.com/GoogleCloudPlatform/healthcare-data-harmonization/tree/master/mapping_configs/fhir_omop

I think one of core problems is that when mapping between two specific data models you lose some information. Depending on mapping OMOP to what FHIR profiles (core resources with or without custom extensions, US core, anything else) you need to choose how to handle that. So, any mapping implementation from OMOP to one particular set of FHIR resources will not easily be reusable by another.
Wouldn't it be more efficient in the long run if we'd model the OMOP data model in FHIR logical models and create one custom set of scripts that transforms the data between those.
Then every next project would only need to map between FHIR logical model conformant data to their profiles of choice, for example with the Mapping Language.

HL7 will soon be commencing a project to align FHIR resources with the OMOP data model. We’re just beginning to discuss scope as of yesterday. Thanks for your timely input, @Ward Weistra

Ward Weistra (Mar 03 2021 at 15:16):

Thanks @Wayne Kubick, let me know if I can be of help

we'll also be inviting HL7 and OHDSI members to participate.

May Terry (Mar 04 2021 at 17:12):

Any chance you can invite me to some of these meetings?
I have been attending a couple of the OHDSI and OMOP working groups for the past couple of months and in a couple of situations have tried making connections between both organizations. For example, I arranged for Christian Reich (OHDSI) to present on the OMOP CDM Genomics extensions to the Clinical Genomics Working Group last month. And in OMOP Oncology Vocabulary, I recommended they reach out to HL7 on how best to manage tooling and other modeling dependencies on the CDM when there is a version update. Perhaps we can build some synergy off of some of these discussions?

Kees van Bochove (Mar 08 2021 at 14:12):

Also, we may be able to build on preparatory work in a number of IMI projects engaged in OHDSI and FHIR, such as IMI EHDEN and especially the new IMI H2O project. The interoperability view from EHDEN has been published here: https://zenodo.org/record/4474373, it shows the high level overlap between OMOP, FHIR, i2b2, CDSIC and GA4GH. H2O is also well positioned to contribute to this working group, please feel free to invite me to participate on behalf of those projects!

Has there been anything new with OMOP and HL7?

Grahame Grieve (May 29 2021 at 23:38):

we are starting to meet regularly to talk about this. We took a break for the WGM but expect action soon. @Wayne Kubick is there more to say?

Josh Mandel (May 30 2021 at 04:16):

I'd love to join too

Jean Duteau (Jun 01 2021 at 02:49):

i don't really have more time on my plate, but I'm very interested in this as well

Jose Costa Teixeira (Jun 03 2021 at 15:01):

any updates on these meetings?

Ward Weistra (Jun 14 2021 at 11:06):

I noticed a newly created #omop + fhir channel. Not a lot of visible action there either, but I'll ask there for an update to centralize :smile:

Friends:

Christian Reich (Jun 23 2021 at 21:33):

My first post here. Have to get used to it. First thing was to click off "Press Enter to send".

Christian Reich (Jun 23 2021 at 21:36):

We are working on a time slot to have the inaugural OHDSI-FHIR kick-off meeting. Will get you all invited. Will have to organize the crowd: get to know each other, adapt to the various habits and rituals, round up all the existing OMOP-FHIR activities, create plans for subgroups and hacka/connectathongs. Please stay tuned.

May Terry (Jun 23 2021 at 23:38):

Excellent! @Christian Reich - Definitely include me in any upcoming meetings. From the OMOP Oncology perspective, it has great parallels to better bridge our mCODE/CodeX work with all the excellent OMOP Oncology work led by you and Rimma, and it also applies to some of our recent MITRE work on building a health platform that supports observational studies.
