Volume 3

Volume 3 of this specifcation describes the agreements and specifications about content.

Data set definitions

• The Zorginzage specification does not describe data sets.
• The Zorginzage specification expects data sets to be descibed using FHIR, in the form of FHIR profiles and FHIR queries.
• The use case specific specifications that are based on Zorginzage have to specify the relevant data set.

Individual resource requests

• Read-requests are only allowed on individual resource types, excluding List-, Composition- and Bundle-resources.
• Search-requests are only allowed on individual resource types, excluding List-, Composition- and Bundle-resources.

Patient Context

All queries that are performed in the context of Zorginzage are patient-specific. The data user needs to know the logical ID of the patient and include it in every query (e.g., patient=123 or subject=Patient/123). The method for obtaining the patient's logical ID is part of the Zorginzage specifcation and must take place as follows:

• an initial search request on the Patient endpoint using the BSN as patient identifier
  • search request must follow IHE PDQm ITI-78 plus the following extra agreements and specifications:
    • Search must be performed on bsn (identifier.system = http://fhir.nl/fhir/NamingSystem/bsn)
    • Only POST-based search is allowed, GET-based search is not allowed
    • The template of POST-based Patient search is included below
• data user organisations MUST support POST-based Patient search
• data holder organisations MUST support POST-based Patient search

Template of POST-based Patient search:

POST {fhir_base}/Patient/_search
