Integration using existing storage solution

EHR-systems that support direct integration through an XDS/XCA API-interface for sharing documents, can utilize these to integrate as a document source.
The primary protocol is SOAP-based communication using the IHE XDS profile.

For documentation on the XDS Metadata format

• Abstract Metadata Model - IHE ITI TF Vol3
• ebRIM Representation - IHE ITI TF Vol3
• Norwegian profile for XDS metadata

Transactions

• ITI-38 - IHE ITI TF Vol2
• ITI-39 - IHE ITI TF Vol2

Slack-channel for integration questions

When integrating with Norsk helsenetts storage solution, you need to be assigned an instance of XcaDocumentSource.
You will get an Object Identifier identifying your instance of XcaDocumentSource. When uploading documents, this identifier must be included in the relevant properties of the FHIR-bundle.
To get an instance of XcaDocumentSource, and for any questions regarding integrations, feel free to contact us in our Slack-channel:

Steps when integrating with existing Storage Solution

As an integrator, you will need an integration layer between your Storage Solution, that can communicate with NHNs XCA Initiating gateway

• The integration layer must accept both ITI-38 and ITI-39 (multipart) requests, and correctly formatted responses.
• The integration layer must handle business logic related to ConfidentialityCodes for citizen and healthcare personell.
• The integration layer must handle access control i.a. PurposeOfUse, HCP Role, HPR number, Organization etc.
