Hi

In FHIR-IL, we are building the Core-IL FHIR profiles for the Israeli healthcare ecosystem. We constantly publish the profiles in the Simplifier tool.

As part of our methodology, when we work on a new profile we use US-CORE (probably what you refer as "Global" FHIR) as a baseline profile, and then try to look at other Cores to learn what kind of modifications they performed in order to see what we can adapt (or avoid). Then, we are deciding what elements to modify, or which extensions to add. It all depends what are the business requirements coming for the Israeli ecosystem. For example, in Patient profile we modified the identifier of the patient to support the different cases of Israeli ids (i.e., israeli-id, palestinian-id ect.), and added extensions such as HMOs, which is very unique to Israel. In other resources, we might not make any modification expect changing the references of the resources from US-Core to IL-Core. Again, it is all depend what is the business case. I encourage you to visit Isreal-Core page . you can find there more explanations about our methodology and the resources we are working on. Also, you can listen to the Webinar in which we explain in more details about our work, the resources we modified and the reasons. Finally, you can see in Simplifier tool, the Release Notes of the different versions of the FHIR-IL project.
