1 Introduction

This is the implementation guide for the information standard eOverdracht, version . This standard is described in this functional specification (TODO) and implemented here using FHIR(STU3) HL7 FHIR, STU3. This implementation guide assumes that the reader is familiar with this FHIR version.

Apart from this document, the guidelines as specified in general FHIR Implementation Guide apply. In particular, the reader should take note of the Use case overarching principles and the use of FHIR packages.

3 Workflow and message structure

3.1 Overview

The use cases within eOverdracht are not isolated, but form a workflow that may include the negotiation of the transfer of the patient, and ends with the transfer of the medical record. In FHIR, this is handled by using a Task resource. This resource tracks the worflow (see #Workflow) and acts as the entry point for all data exchanges (see #Use of the Composition resource) for the transfer of care for a patient.

3.2 Task

3.2.1 Task requirements

The requirements for the Task resource in the eOverdracht context are specified using the http://nictiz.nl/fhir/StructureDefinition/eOverdracht-Task profile. This profile SHALL be used for the eOverdracht workflow.

The Task instance SHALL be hosted on the server of the sending XIS. Both the sending and the receiving XIS need to be able to update the Task. The sending XIS MAY use business rules to reject an update, for example if invalid status change is used.

Both the sending and the receiving XIS SHALL monitor the Task resource for changes. It is expected that the sending XIS will use a notification mechanism to inform the receiving XIS of creation or updates of the Task (see #Notifications), but the receiving XIS could use a polling mechanism as well.

For each combination of sending and receiving XIS, a dedicated instance of the Task resource SHALL be used for each transfer situation. This is true even when the sending XIS wants to send the same request to multiple parties. The reason for this is that the Task status is used to negotiate the transfer of care, so it cannot be used simultaneously for multiple recipients.

3.2.2 Task invocations

Notifications to the receiving XIS are not expected to contain a logical id to the Task. Hence, the receiving XIS should use a combination of a search interaction and the _lastUpdated search parameter to retrieve the eOverdracht Tasks that have been added are changed since the last invoation:

 GET base/Task?code=[TODO]&_lastUpdated=[time of last request]

Note 1: More than one result can be returned, for example when an additional Task can have been modified before the notification has been sent, when the receiving XIS choose to batch search interactions, etc.

Note 2: It is up to the receiving XIS to detect if a result is a new Task instance or a change to an existing instance, and if so, what has been changed since the last invocation.

The receiving XIS can update a Task hosted by the sending XIS using a PUT operation:

 PUT base/Task/[id]

The body should be the original Task with the needed modifications. The sending XIS SHOULD check the update for errors and inconsistencies. If the update is rejected, the sending XIS SHALL response with a HTTP 422 status code and an OperationOutcome detailing the problem.

3.2.3 Notifications

It is expected that the sending XIS will notify the receiving XIS when a new Task is created or when an existing Task is updated. Although the notification mechanism is out of scope for the eOverdracht information standard, it is assumed that the notification does not contain a Task resource id. Rather, it signals that the receiving server should perform a search at the sending server to look for additions or changes in the eOverdracht Task resources.

A straightforward implementation for this notification mechanism is for the notifying party to make an empty POST request on a pre-determined endpoint at the party that should be notified. This could be arranged using the FHIR subscriptions mechanism, but the endpoints could also be arranged by other means.

3.3 Use of the Composition resource

The Aanmeldbericht and the (three variants of) the Overdrachtbericht are mainly built up of individual FHIR resources, selected by the sending organization to form a coherent set of information relevant to the receiving organization. The bulk of these resources are not referenced directly from the Task. Instead, the Task references a Composition resource which in turn assembles the references to all individual FHIR resources. For this purpose, the Composition profiles described in #FHIR profiles SHALL be used.

3.3.1 Composition invocations

The receiving XIS MAY use either of the following mechanism for retrieving the individual FHIR resources referenced in the Compostion resource.

As a Document
The receiving XIS uses the $document operation to retrieve both the Composition and all referenced resources as a single document Bundle.
GET [base]/Composition/[id]/$document
Individual requests
The receiving XIS first retrieves the Composition resource
GET [base]/Compositon/[id]
Then the necessary other resources referenced can be fetched using a GET interaction.

The sending XIS SHALL support both mechanisms.

3.4 Using Task to manage the workflow

The Task is the main entry point for the eOverdracht transactions. The eOverdracht workflow starts with the retrieval of a new Task instance by the receiving XIS, and all subsequent steps in the worflow are mediated by updates to this Task instance.

The eOverdracht transactions are mapped to FHIR in the following way:

eOverdracht transaction Task
Send Aanmeldbericht
  • sending XIS creates Aanmeldbericht Composition
  • sending XIS creates Task:
    • Task.status = requested
    • Task.input:aanmeldBericht contains reference to the Aanmeldbericht Composition resource
  • (sending XIS sends notification to receiving XIS)
Send Antwoordbericht
Accept transfer
  • receiving xis updates Task:
    • Task.status = accepted
    • optionally: Task.owner set to receiving organization. See #Brokers.
Reject transfer
  • receiving xis updates Task:
    • Task.status = rejected
Propose alternate date
  • receiving xis updates Task:
    • Task.status = on-hold
    • Task.output:alternatieveDatum contains alternate proposed date
Respond to alternate proposed date
Accept alternate proposed date:
  • sending XIS updates Aanmeldbericht Composition
    • new date/time for overdracht
  • sending xis updates Task:
    • Task.status = requested
  • (sending XIS sends notification to receiving XIS)
Reject alternate proposed date:
  • sending xis updates Task:
    • Task.status = cancelled
  • (sending XIS sends notification to receiving XIS)
Send Overdrachtbericht
  • Sending XIS creates Overdrachtbericht Composition
  • Sending XIS updates Task:
    • Task.input:overdrachtBericht contains reference to the Overdrachtbericht Composition resource
  • (sending XIS sends notification to receiving XIS)
Send confirmation of Overdrachtbericht
  • Recieving XIS updates Task:
    • Task.status = completed

3.4.1 Partial workflow

When the transfer has to be carried out without the negotiation phase, the sending XIS will create the Task instance with Task.status already set to accepted and Task.input:overdrachtbericht populated.

3.4.2 Brokers

The use of a broker to find an available healthcare provider for the patient transfer fall outside the scope of the eOverdracht information standard. However, it is possible to start the workflow without knowing the receiving organization, which allows for the use of a broker. In this situation, for the sending XIS the broker acts as a receiving XIS, and for the receiving XIS the broker acts as a sending XIS.

When Task.input:overdrachtbericht is populated with the Overdrachtbericht Composition, Task.owner MUST be populated with the receiving organization.
