Topic: IHE SDC

Does anyone know the difference between the Structured Data Capture (SDC) standards maintained by IHE and FHIR? The backstory I’ve heard about two harmonious efforts both spun off by ONC in 2017 doesn’t seem to align with my observation that neither effort seems to reference the other very much in their online documentation and message boards.
My initial take is that IHE seems more focused on implementing the various components in an SDC system (e.g., form filler, form manager, etc.) while FHIR is working more on being able to describe complex Questionnaires and their behaviors. Can anyone shed some light on whether IHE and FHIR SDC are complementary, duplicative, or orthogonal?
I’m also confused as to why this implementation guide is necessary given the active work being done on SDC by the FHIR community.

IHE's SDC uses a custom syntax to represent the Questionnaire & response. HL7's uses FHIR. The capabilities of each spec have diverged

Thanks @Lloyd McKenzie , that's unfortunate. Does anyone know if a reconciliation is in the cards going forward?
Lloyd McKenzie (Oct 26 2020 at 16:24):
The IHE spec pre-dated the FHIR one by about a year and there were parts of the IHE community weren't enamored with the HL7 FHIR representation. I'm not aware of any near-term plans for reconciliation. Reconciliation would be hard given that the syntaxes are pretty different.
Lloyd McKenzie (Oct 26 2020 at 16:26):
(IHE uses the same structure for both representing the Questionnaire and the response, FHIR uses separate resources)
David Winters (Oct 26 2020 at 16:30):
Okay, then that explains the purpose of the IHE SDC on FHIR IG: Get the IHE combined Questionnaire/QR structure into FHIR. Interesting that it entails side-stepping FHIR QR and goes straight to Observation resources.
Lloyd McKenzie (Oct 26 2020 at 16:43):
So sort of a light-weight 'extraction' process. (HL7 SDC has that, but supports extraction to much more than just Observations.)
David Winters (Oct 26 2020 at 16:45):
Yup, I'm familiar with what's possible with HL7 SDC, but am coming up to speed on the IHE alternative. Thanks for the help @Lloyd McKenzie.

is it possible that IHE has produced a FHIR version under Mobile Retrieve Form for Data Capture -- https://wiki.ihe.net/index.php/Mobile_Retrieve_Form_for_Data_Capture

Mr. Stamm is the best person to speak to this. My intent with mRFD was to profile mere SMART in IHE.
