Introduction to IHE Use Cases

InterSystems provides business services, business processes, and business operations that you can use to implement the IHE profiles, actors and transactions supported by InterSystems. This book does not document all business hosts that are available, but rather provides an introduction to a few important use cases. For the complete list of IHE profiles, actors, options, and transactions supported by InterSystems products, see the InterSystems IHE Integration StatementsOpens in a new tab.


Prior to using a FHIR®-based profile, you need to enable the HS_Services user. To enable the user, open the Management Portal and navigate to System Administration > Security > Users. Select HS_Services, and then select User Enabled.

For each use case in this book, messages are traced through the product. A table lists the components and settings employed in each use case, and examples provide instructions on creating messages for input.
