BWorp opened Issue #79
We would like to implement this use-case with CDS Hooks.
- CDS request for starting of a calculation.
- Returning the result of this calculation.Quite basic, but the calculation takes a long time, typical several minutes.
I don't think that sending the response after finishing the calculation is good practice.
So the idea is to send a CDS response after basic intake of pre-fetched data.
After the calculation is completed, it is then needed to push the status / result.1. - One way within CDS Hook context I see is mis-use a ad-hock request to the EHR FHIR service to push the status.
2. - Or use the redirect URL from the request to push status.
3. - Or add a proprietary URL in the request for this purpose
4. - Polling using a second CDS request is possible, using a elapsed time indication returned in the CDS Hook reply, is possible but not preferred.Please advice. Am I missing or misinterpreting something?
Please also refer to this Zulip topic. https://chat.fhir.org/#narrow/stream/cds-hooks/subject/CDS.20async.20reply/near/93110
Thanks in advance, Bart.
