Transactions and documents


Most of the core functionalities of the ZorgDomein application are based on the concept of “transactions”. A transaction a defined as a set of interactions between a healthcare professional on the one hand and a healthcare organization or professional on the other hand in the context of a single patient. A transaction is identified by its ZD-number. ZorgDomein currently supports the following transaction types:

  • Referrals
  • Requests for healthcare services or products, such as:
    • Diagnostic research (both lab and non-lab)
    • Teleconsultation
    • Placement requests (NL: plaatsingsverzoeken in de context van de verpleegkundige overdracht)
    • Execution requests (NL: uitvoeringsverzoeken)
    • Medical devices
  • Reports (e.g. admission, progress, discharge and incident reports)
  • Transfer dossiers


The interactions between the involved parties in a transaction are implemented by the exchange of documents. This means that the initiator of a transaction can initiate a transaction by generating one or more documents in ZorgDomein and sending these documents to the intended recipient. On the other hand, the recipient may respond to these incoming documents by generating one or more documents in ZorgDomein and sending these to the initiator of the transaction, within the scope of the same transaction. It is also possible for the recipient to respond on the initial transaction by generating a new transaction in ZorgDomein, depending on the transaction type and the user flow that the user chooses in the ZorgDomein user interface.

All documents that are related to a single transaction share the same ZD-number, which is a ZorgDomein identifier for a transaction. This way all incoming documents with the same ZD-number can be logically grouped in the same transaction.

Document types

Each transaction involves the exchange of one or more document types to transfer the request or message. ZorgDomein has implemented different document types that are used in the different transaction types. See the Document type code system for a complete list of all possible document types. 

The table below shows which document types are typically implemented in the different transaction types: 

  Referral Service request Report Transfer
Appointment request Yes No No No
Referral letter Yes No No No
Request form Sometimes Yes No No
Questionnaire Sometimes Sometimes No No
Supplement Yes Sometimes No No
Cancellation Yes Sometimes No No
Report No No Yes No
Response No Sometimes No No
Transfer dossier No No No Yes


When sending a document like a referral letter or request form, the sender may optionally add one or more attachments to the document. These attachments will be delivered in a separate document. This attachment document is always linked to the main document. Note that this document may contain multiple binary attachment files.
