1 Note on this Implementation Guide - alpha status

This alpha version of the Implementation Guide (TO) is not technically complete, but even so, it is being published in order to start obtaining feedback from the stakeholders. The current version provides an early indication of the contents being proposed.

The following items require further investigation, discussion and review amongst all stakeholders.

1. Generic description of the Notified Pull communication pattern - this is being developed by Team Radar (Generic) within Nictiz at the moment and will be referred to from this TO. The intention is to avoid duplicating information at all costs.
2. FHIR Notification and Workflow Task profiles - the first versions of these have been developed locally and now need to be published via Simplifier so that a reference can be made to them from this TO.
3. FHIR GET (read/search) request strings - these need to be reviewed once the Referenced BgZ Resource profiles are complete.
4. FHIR Referenced BgZ Resource profiles - the FO defines two new data elements that enrich the BgZ items - EersteRegistratieDatumTijd (FirstRegistrationDateTime) and MutatieDatumTijd (ContentModificationDateTime). These two fields need to be added to the corresponding BgZ FHIR resources and the mechanism for doing this is under discussion at the moment. The FHIR Provenance Resource is being considered. As soon as there is some clarity on best practices then the FHIR resource profiles will be updated and references adjusted in this TO.

The intention is to finalize agreements on these issues for the beta version of the TO. This alpha version will be updated, towards a beta version, as issues are resolved.

2 Introduction

2.1 Background

The BgZ MSZ Information Standard describes the exchange of the BgZ information between healthcare providers. The BgZ information is the minimum collection of patient data that is relevant across specialty, syndrome and profession and is important for the continuity of care. This data collection can be exchanged between care institutions. The information standard focuses on the exchange between healthcare providers of specialist medical care.

This BgZ MSZ implementation guide defines the BgZ information exchanges, in terms of use cases, based on the Zib2017 and HL7 FHIR STU3 releases. HL7 CDA is no longer supported for BgZ MSZ exchange.

2.2 About this document

This BgZ MSZ implementation guide is a technical document defining the BgZ information exchanges in terms of use cases. It should be used together with the BgZ MSZ Functional Design (FO) - see Functioneel ontwerp BgZ medisch-specialistische zorg 2.0 alpha.

The following documents also provide important background information:

• "Kwaliteitsstandaard - Uitwisseling Basisgegevensset Zorg tussen instellingen waar medisch-specialistische zorg wordt verleend" (which translates as “Exchange of BgZ between institutions where specialist medical care is provided”) [1]
• "NEN 7540:2024 BgZ-uitwisseling tussen instellingen voor medisch specialistische zorg" (which translates as “Exchange of BgZ between institutions for specialist medical care”) [2]
• "Technical Agreement - Exchanging FHIR Data using a generic Notified Pull mechanism" [3]

This document assumes reader familiarity with these references.

This implementation guide is intended to provide information for implementation/deployment needs in the Netherlands. This document is part of an evolving strategy, features will likely be added, adjusted and/or removed in future versions.

2.3 Glossary

Term	Description
Basisgegevensset Zorg - medisch-specialistische zorg (BgZ MSZ)	Minimum collection of patient data that is relevant across specialty, clinical picture and profession and is important for the continuity of care.
BSN	The citizen service number (BSN) is a unique 9-digit personal number allocated to everyone registered in the Personal Records Database (BRP). Everyone who registers with the BRP is automatically given a BSN.
FHIR	Fast Healthcare Interoperability Resources
IHE	Integrating the Healthcare Enterprise
HCIM	Health and Care Information models (HCIM) or Zorginformatiebouwstenen (ZIB's) are used to capture functional, semantic (non-technical) agreements for the standardization of information used in the care process.
MedMij	MedMij is an initiative of the Dutch Patient Federation and was embraced as one of the five focus programs in 2015. The Healthcare Information Council then opted for the MedMij program. To make healthcare better, more affordable and more accessible, the Information Council is working on a sustainable information system for healthcare, in which healthcare data is exchanged securely and reliably. To this end, agreements, standards, and facilities are made, together with the participants of the Information Council.
VZVZ	Vereniging van Zorgaanbieders voor Zorgcommunicatie: Dutch Association for Health Providers
Zib	A Zib (Zorginformatiebouwstenen) defines a clinical concept in such a way that it can be used as a building block in various healthcare situations and information systems. ZIBs form the basis for the standardization of healthcare information.

3 Boundaries and Relationships

This is the first version of the BgZ MSZ information standard in which the Notified Pull communication pattern is used to implement the "Exchange BgZ for Referral" use case. A generic description of the Notified Pull communication pattern is available (add link the Nictiz Team Radar/Generic NP description). The generic description is supplemented in this Implementation Guide by specific details defining:

1. The Notification and Workflow Tasks in terms of their FHIR profiles.
2. The GET request strings required to read/search for the BgZ MSZ items, defined as Input parameters in the Notification/Workflow tasks, from the Sending System by the Receiving System.
3. The referenced FHIR resource profiles corresponding to the BgZ MSZ items.

4 Use Cases

Two use cases are defined in the FO as follows:

• Exchange BgZ for Referral ("Uitwisseling BgZ bij Verwijzing") from a referring (sending) healthcare provider to a receiving healthcare provider in the event of a planned referral or transfer between their two care institutions.
• Retrieval of BgZ from previous practitioner ("Opvraging BgZ bij eerdere behandelaar") by a requesting healthcare provider to his/her care institution from a different care institution.

The difference between the two use cases is mainly down to which healthcare provider takes the initiative to start the exchange of the BgZ.

4.1 Exchange BgZ for Referral

In the "Exchange BgZ for Referral" use case, the current healthcare provider (Referring (Sending) Medical Specialist) takes the initiative for a referral or transfer. In doing so, information is shared, including the BgZ (and, for example, a referral letter, additional images or reports). When the patient then attends the new care institution as a result of the referral, or transfer, the Receiving Medical Specialist can (re)use the information from the BgZ.

4.1.1 Actors

Persons		Systems
Name	Description	Name	Description
Referring (Sending) Medical Specialist	Medical specialist who sends a BgZ along with a referral	EHR	Electronic health record
Receiving Medical Specialist	Medical specialist receives a BgZ along with a referral	EHR	Electronic health record

It is assumed that the Referring (Sending) Medical Specialist and Receiving Medical Specialist, as persons who use the BgZ sharing infrastructure, are signed on, authenticated and have authorization & consent to access the necessary (patient) information stored in the BgZ sharing infrastructure (or in other words, an authenticated healthcare professional who has an active treatment relationship with the patient). The way in which the persons achieve this state is beyond the scope of this implementation guide but is expected to be facilitated by use of the generic infrastructure.

4.1.2 Transactions

The "Exchange BgZ for Referral" use case can be implemented using two types of transactions:

• Notified Pull (preferred)
• Push

4.1.2.1 Exchange BgZ for Referral using Notified Pull Transaction

The Notified Pull transaction is based on the description in [3]. The Referring (Sending) Medical Specialist notifies the Receiving Medical Specialist about the referral or transfer by sending a Notification Message. The Receiving Medical Specialist can then retrieve the BgZ (at a suitable time) using the Pull Message(s) which is(are) defined as a part of the Notification Message.

This two stage approach separates the notification phase from the actual BgZ retrieval phase allowing the Receiving Medical Specialist to decide if, and when, to retrieve the BgZ.

TODO: Linked to be added to the generic description of the Notified Pull communication pattern...

The Workflow (Task) message is optional in the BgZ MSZ exchange and no statement about it's inclusion is made by this Implementation Guide. However, in terms of system support the following rules apply:

1. The Sending System can support either a standalone Notification (Task) message or the combined use of the Notification (Task) and Workflow (Task) messages.
2. The Receiving System must support both the Notification (Task) and Workflow (Task) messages.

The FHIR profiles describing the Notification (Task) message, the Workflow (Task) message and the retrieved BgZ item resources are defined in the FHIR Profiles section.

The FHIR search/read queries used to retrieve the BgZ item resources are defined in the FHIR Task.input Query Specification section.

4.1.2.2 Exchange BgZ for Referral using Push Transaction

The Referring (Sending) Medical Specialist pushes the BgZ to the Receiving Medical Specialist at the time of referral or transfer and not necessarily at the time when the Receiving Medical Specialist requires the BgZ (if it is required at all).

The Push method always transfers the BgZ to the Receiving Medical Specialist even when it might not be wanted or needed.

The FHIR profiles describing the BgZ item resources are defined in the FHIR Profiles section.

Note: The Push use case can be used by systems transitioning from HL7 CDA to HL7 FHIR where the CDA based BgZ is replaced by a FHIR Composition and pushed between sending and receiving systems.

4.2 Retrieval of BgZ from previous practitioner (out of scope V2.0)

In the "Retrieval of BgZ from previous practitioner" use case, the current healthcare provider (Requesting Medical Specialist) is aware that the patient has had some previous treatment (through, for example, information provided by the patient) and takes the initiative to retrieve the details of this previous treatment from the previous care institution.

4.2.1 Actors

Persons		Systems
Name	Description	Name	Description
Requesting Medical Specialist	Medical specialist who queries for a BgZ	EHR	Electronic health record

It is assumed that the Requesting Medical Specialist, as person who uses the BgZ sharing infrastructure, is signed on, authenticated and has authorization & consent to access the necessary (patient) information stored in the BgZ sharing infrastructure (or in other words, an authenticated healthcare professional who has an active treatment relationship with the patient). The way in which the person achieves this state is beyond the scope of this implementation guide but is expected to be facilitated by use of the generic infrastructure.

4.2.2 Transactions

4.2.2.1 Retrieval of BgZ from previous practitioner using Pull Transaction

The Requesting Medical Specialist can retrieve the BgZ (at a suitable time) using the Pull Message.

The FHIR profiles describing the retrieved BgZ item resources are defined in the FHIR Profiles section.

The FHIR search/read queries used to retrieve the BgZ item resources are defined in the FHIR Task.input Query Specification section. The Task.input.value[x] definitions define the query search/read values to use.

5 FHIR Profiles

Note: These FHIR Profiles are under review and will be finalized by the beta version of the TO.

5.1 FHIR Notification Task

A BgZ MSZ Notification Task instance is created in the Receiving System by the Sending System issuing an HTTP POST operation to the Receiving System.

The following table identifies the location of the Notification Task FHIR profile.

FHIR Resource	FHIR Profile
(Notification) Task	http://fhir.nl/fhir/StructureDefinition/bgz-msz-notification-task-location-to-be-added

5.2 FHIR Workflow Task

If the Sending System supports the management of the BgZ MSZ information exchange, it will create a Workflow Task instance locally, and include details of the Workflow Task in the Notification Task exchanged with the Receiving System. The Recieving System can retrieve the Workflow Task by issuing an HTTP GET operation to the Sending System.

The following table identifies the location of the Workflow Task FHIR profile.

FHIR Resource	FHIR Profile
(Workflow) Task	http://fhir.nl/fhir/StructureDefinition/bgz-msz-workflow-task-location-to-be-added

5.3 FHIR Task Patient Identification

Although a patient is formally identified by their BSN in the BgZ MSZ information standard, this patient identifier is never exchanged as part of either the Notification Task or Workflow Task content. Instead, an "authorization base" token is exchanged, which only gives access by the Receiving System to specific data of a single patient managed by the Sending System.

The authorization base token is exchanged as one of the Task.input parameters in the Notification Task with a format as shown in the table below.

FHIR Task.input.type	FHIR Task.input.value[x] as valueString
codeSystem: http://fhir.nl/fhir/NamingSystem/TaskParameter code: authorization-base	authorization base token value (encrypted)

5.4 FHIR Task.input Query Specification

The following table provides the overview of the FHIR query (read/search) operations needed to retrieve all the BgZ MSZ items. These queries will be specified as Task.input (type and value[x]) parameters.

The Type column defines the type of query:

• Read - query for a single referenced FHIR resource instances where value[x] is a valueReference.
• Search - query for one or more FHIR resource instances where value[x] is a valueString representing the search string.

The Code (FHIR Task.input.type) column defines codedConcepts that identify the BgZ MSZ item to retrieve. Each codedConcept is defined in terms of the codeSystem, code and display name. NOTE: The SNOMED-CT codeSystem is used for the majority of the BgZ MSZ item identification (as required by the SNOMED-CT usage policy (add reference)). LOINC is also used to identify some BgZ MSZ items where no SNOMED-CT code is available.

The Value (FHIR Task.input.value[x]) column defines the query performed to retrieve the identified BgZ MSZ item.

The same Task.input parameters are applicable to the Notification Task or the Workflow Task depending on which is used to specify the BgZ MSZ retrieval operation.

NOTE to information standard reviewers: This is table defines the core BgZ MSZ Notified Pull contents and must be reviewed, accepted and adopted by all stakeholders. Please review very carefully.

6 Infrastructure

The implementation guideline assumes that a generic infrastructure is available to provide for services like:

• Identification [NEN-7518] (of client and provider - who are you?)
• Authentication [NEN-7518] (establish that you really are who you say)
• Localization [NEN-7519] (where/what information known about the client and provider?)
• Consent [NEN-7517] (from the patient for the sharing of medical information)
• Authorization (what information are you allowed to access?)
• Addressing (digital address of provider or organization)
• Logging [NEN-7513] (audit trail - who did what, where, when and why?)
