Implementation guide

[shuhaibk54]

How I can implement the FHIR server using this, I mean basically document where it talks about data mapping with my HIS system. Any good implementation doc or video.Please help

@shuhaibk54 - Can you give me a bit more information on what you mean by this. If you can give me more details on what you're trying to implement we can help point you in the right direction.

@CaitlinV39 - I am trying to build a FHIR server connecting to my existing HIS database. I have to see the implementation guide on how this URL search query will retrieve from the HTTP URL and pass it to my SQL server to get the data.
Based on the table data i should be able to create the Bundle/Resource based on the URL search. The whole idea is to create the search functionality for my HIS system. Let me know if you need a detailed explanation as well again.

Hey Shuhaibk - Unfortunately we don't have a generic implementation guide to put the FHIR server on top of an existing database. While its possible, we optimize the documentation to deploy a new FHIR server with a new backend. I'll leave this as unanswered incase someone in the community has done this and has recommendations on how to get started.

Thanks for the response @CaitlinV39. Let me know if in case you found any document for this, which make my life easy to get started :)

@CaitlinV39: Any other document which I can at least get started using this project, where to start, and how to debug and configure. Want to see where it's going to hit If I am passing something like this "http://localhost:5050/Observation/1234. Then I can have my own wrapper project which can communicate to my DB. That's what I am thinking.

A slightly different approach is the leave the FHIR Server intact and use FHIR Proxy (https://github.com/microsoft/fhir-proxy). In essence the FHIR Server would maintain its own "FHIR" copy of the data, giving you better scalability and full native FHIR Search etc. The FHIR Proxy would allow interception of the calls that need to be created/updated/Deleted in the source system, basically a two-way sync.

@brendankowitz: Thank you so much. Will this support compartment searching, or do we need to modify it accordingly to make compartment search available.
For example : GET [base]/Patient/[id]/Condition?code:in=http://hspc.org/ValueSet/acute-concerns

[brendankowitz]

If the data is loaded into the FHIR Server you should have access to all search features. Compartment searches are supported, I don't think the :in modifier is supported yet (https://docs.microsoft.com/en-us/azure/healthcare-apis/azure-api-for-fhir/overview-of-search)

[shuhaibk54]

Got your point. Whatever the case proxy service also going to hit the FHIR server service to perform the REST operation. We may have to maintain some document that says how to customize the FHIR server service according to individual DB requirements (Especially our DB column to FHIR model element mapping and customization)

@anyone: Any hint where it hit the controller lever of the FHIR server when we do any REST operation, let us say.
for example http://localhost:5000/Encounter/6431519 , Will this hit somewhere here Microsoft.Health.Fhir.Api.Controllers( FhirController) . I tried it does not work . Any advice for just getting started.
