Introduction

This page details the HL7 FHIR requirements for exchanging the Geboortezorg v2.3 data described in Functioneel.

A high level overview:

Use case: Register Prio1 data

Introduction

The Register Prio1 transaction is used by the sending XIS to send the relevant data to the registry.

Actors

Transaction group	Transaction	Actor	Role
Register Prio1(PUSH)	Register Prio1	Healthcare professional (using a XIS)	Sends Prio1 data to registry
Retrieve Prio1(PULL)	Querying XIS	Healthcare professional (using a XIS)	Retrieves Prio1 data from registry

Invocations

Sending XIS: request message

Message Semantics

The source executes two HTTP requests:

1. HTTP POST request

A HTTP POST request of a Bundle with Bundle.type = transaction to the target's base endpoint. The first Bundle.entry contains a Composition resource, and each subsequent entry contains a resource that is referenced from the Composition resource.

POST [base]{&_format=[mime-type]}

Each Bundle.entry shall contain an entry.request with request.method = PUT. Each Bundle.entry shall contain either:

1. A client assigned UUID in the entry.resource and the entry.request.url
2. A conditional reference in the entry.fullUrl and the entry.request.url

The first applies to resources (e.g. Observations) of which multiple instances are allowed to live on the server.

The second applies to resources (e.g. Patients) for which no duplicates are allowed, e.g. by identifier. Please note that resource instances with conditional references are only created when no resource instance on the server meets the condition, updated when one such an instance exists and the transaction is fully rejected when multiple resource instances meet the condition. Also note that the internal references in the transaction pointing to these kind of resource instances are conditional ones.

Below are examples of transaction Bundles for the prio1 transaction:

• Current pregnancy
• Previous pregnancy

2. HTTP GET request

A HTTP GET request to the target's Composition endpoint, handling the createDocumentOperation with persist=true. The target's response is a FHIR Document Bundle, which is generated from the Composition resource and stored to the target's Bundle endpoint.

GET [base]/Composition/[id]/$document?persist=true{&_format=[mime-type]}

Retrieving XIS: request message

FHIR Document Bundles can be retrieved by a HTTP GET request to the target's Bundle endpoint. Note that FHIR Document Bundles are immutable and its entries refer to a time-related version of a resource which is not necessarily its latest version.

GET [base]/Bundle/[id]{&_format=[mime-type]}

Individual resources can be retrieved by HTTP GET requests to specific resource endpoints, see the Search section and list of StructureDefinitions below.

Examples

Example FHIR resources can be found here: [1]

Example search URLs can be found in the list of StructureDefinitions below. Some searches require the implementation of custom search parameters. These parameters can be found here: https://simplifier.net/geboortezorg-stu3/~resources?category=SearchParameter

FHIR Resources and StructureDefinitions

Graphical overview

The following link Media:FHIR Geboortezorg Profielen Prio1 23-03-2020.png provides a graphical overview of the structure definitions and their relations.

Types of resources and relations between them

For pregnancy-, delivery- and child related observations detailed information is given, follow links below.

Name	FHIR resource	Description
Woman (Vrouw)	Patient	The core of each pregnancy is the pregnant woman, a FHIR Patient.
Generic resources	Practitioner, PractitionerRole, Organization	Those are not used differently than in other Dutch projects.
Pregnancy, Pregnancy file (Zwangerschap, zwangerschapsdossier)	Condition, EpisodeOfCare	Each pregnancy is a Condition. It is also represented as an EpisodeOfCare for each involved Organization. The pregnancy includes references to an Organization and responsible Practitioner. (Practitioners responsible for the actual data may be included there, i.e. in Procedures, Observations.) Condition points to the EpisodeOfCare through a EpisodeOfCare.context.reference element. (Note: different providers may each have their own Condition resource.) EpisodeOfCare points to the Condition through a EpisodeOfCare.diagnosis.condition element. Condition points to the Patient with Condition.subject.reference Condition.status must be 'active' for ongoing pregnancies and 'inactive' for past ones.
Patient-related Observations	Observation	Observations such as blood type pertain to the Patient. Observations can refer to an EpisodeOfCare with Observation.context.reference
Pregnancy-related Observations	Observation	Observations such as gravidity and parity do not (only) pertain to the Patient but to a particular pregnancy. Pregnancy-related Observations use focus extension to point to Condition they're about. Without this, all gravidities would only be Observations about a Patient. Pregnancy-related Observations refer to the EpisodeOfCare with Observation.context.reference
Delivery (Bevalling)	Procedure	Delivery is modeled with Procedure (even for uncomplicated natural births for consistency). Delivery refers to the EpisodeOfCare with Observation.context.reference
Obstetric Procedures	Procedure	Obstetric Procedures, such as vacuum delivery, are Procedures conducted as part of the Delivery Procedure. Obstetric Procedures use Procedure.partOf element to point to the delivery Procedure they're part of. Obstetric Procedures refer to the EpisodeOfCare with Observation.context.reference
Delivery-related Observations	Observation	Observations such as onset of labor or blood loss pertain to a delivery Procedure. Delivery-related Observations use focus extension to point to the delivery Procedure they're about. Delivery-related Observations refer to the EpisodeOfCare with Observation.context.reference
Birth	Observation	A birth pertains to a delivery Procedure as well as a child, especially in multiple birth where multiple Birth instances point to the same delivery Procedure. A birth also provides the relation between a child and its mother, which is still the subject of the record. Birth uses focus extension to point to the delivery Procedure. Birth uses focus extension to point to the child Patient. Birth refers to the EpisodeOfCare with Observation.context.reference
Birth-related Observations	Observation	Observations such as parturition type pertain to a birth. They are also about the mother, which still is the subject. Birth-related Observations use focus extension to point to a birth. Birth-related Observations refer to the EpisodeOfCare with Observation.context.reference
Child	Patient	Child is a separate Patient. Procedure-related Observations use focus extension to point to the child Patient they're about.
Child-related Observations	Observation	Observations such as Apgar score and birthweight pertain to the child Patient, which is the subject of these Observations. Child observations refer to the EpisodeOfCare with Observation.context.reference

The use of focus extensions is a pre-adopt of FHIR R4, where it is part of Observation: "What the observation is about, when it is not about the subject of record." Focus is required for all Observations which do not pertain to the Patient. In R4, use of focus permits "reverse include" queries (give me all Observations with focus element X). In STU3, this could be a custom search.

The use of context is encouraged for all resources which have a context element. It is a reference to an EpisodeOfCare or an Encounter. Context should point to an Encounter when appropriate (scheduled maternity checks etc.) and to the EpisodeOfCare in all other cases. Possibly it will be absent in Observations where the source is not birth care, so readers should not rely on it's presence.

Observations should include a performer if known.

List of StructureDefinitions

Please note that many birth care specific profiles are derived from nl-core profiles (e.g. bc-PregnancyObservation is derived from nl-core-observation) to support (re)use of profiles in multiple use cases. The meta.profile element of FHIR instances conforming these profiles should at least include the generic nl-core profile and preferably the specific birth care profile.

Use case: Register Parturition Record

Introduction

The Register Parturition Record transaction is used by the sending XIS to send the relevant data to the registry.

Actors

Transaction group	Transaction	Actor	Role
Register Parturition Record(PUSH)	Register Parturition Record	Healthcare professional (using a XIS)	Sends Parturition Record data to registry
Retrieve Parturition Record(PULL)	Querying XIS	Healthcare professional (using a XIS)	Retrieves Parturition Record data from registry

Invocations

Sending XIS: request message

Message Semantics

The source executes two HTTP requests:

1. HTTP POST request

A HTTP POST request of a Bundle with Bundle.type = transaction to the target's base endpoint. The first Bundle.entry contains a Composition resource, and each subsequent entry contains a resource that is referenced from the Composition resource.

POST [base]{&_format=[mime-type]}

Each Bundle.entry shall contain an entry.request with request.method = PUT. Each Bundle.entry shall contain either:

1. A client assigned UUID in the entry.resource and the entry.request.url
2. A conditional reference in the entry.fullUrl and the entry.request.url

The first applies to resources (e.g. Observations) of which multiple instances are allowed to live on the server.

The second applies to resources (e.g. Patients) for which no duplicates are allowed, e.g. by identifier. Please note that resource instances with conditional references are only created when no resource instance on the server meets the condition, updated when one such an instance exists and the transaction is fully rejected when multiple resource instances meet the condition. Also note that the internal references in the transaction pointing to these kind of resource instances are conditional ones.

Below are examples of transaction Bundles for the prio1 transaction:

• Current pregnancy
• Previous pregnancy

2. HTTP GET request

A HTTP GET request to the target's Composition endpoint, handling the createDocumentOperation with persist=true. The target's response is a FHIR Document Bundle, which is generated from the Composition resource and stored to the target's Bundle endpoint.

GET [base]/Composition/[id]/$document?persist=true{&_format=[mime-type]}

Retrieving XIS: request message

FHIR Document Bundles can be retrieved by a HTTP GET request to the target's Bundle endpoint. Note that FHIR Document Bundles are immutable and its entries refer to a time-related version of a resource which is not necessarily its latest version.

GET [base]/Bundle/[id]{&_format=[mime-type]}

Individual resources can be retrieved by HTTP GET requests to specific resource endpoints, see the Search section and list of StructureDefinitions below.

FHIR Resources and StructureDefinitions

Types of resources and relations between them

For pregnancy-, delivery- and child related observations detailed information is given, follow links below.

Name	FHIR resource	Description
Woman (Vrouw)	Patient	The core of each pregnancy is the pregnant woman, a FHIR Patient.
Partner	RelatedPerson	The partner of the pregnant woman (not necessarily the biological father).
Generic resources	Practitioner, PractitionerRole, Organization	Those are not used differently than in other Dutch projects.
Referral details	ReferralRequest	Referral details (such as type of referral, reason code, referrer and target of the referral) are described in ReferralRequest. The pregnant woman is the subject, the context is the pregnancy file (EpisodeOfCare).
Involvement pediatrician	CareTeam	A CareTeam describes the involvement of different care providers, such as a pediatrician. These care providers are included as participants in the CareTeam using the CareTeam.participant.member element. Participants may either be Practitioners or Organizations. Their role and period of involvement are described at the participant level (that is CareTeam.participant.role and CareTeam.participant.period). The reason of involvement is described in CareTeam.reasonCode
Pregnancy, Pregnancy file (Zwangerschap, zwangerschapsdossier)	Condition, EpisodeOfCare	Each pregnancy is a Condition. It is also represented as an EpisodeOfCare for each involved Organization. The pregnancy includes references to an Organization and responsible Practitioner. (Practitioners responsible for the actual data may be included there, i.e. in Procedures, Observations.) Condition points to the EpisodeOfCare through a EpisodeOfCare.context.reference element. (Note: different providers may each have their own Condition resource.) EpisodeOfCare points to the Condition through a EpisodeOfCare.diagnosis.condition element. Condition points to the Patient with Condition.subject.reference Condition.status must be 'active' for ongoing pregnancies and 'inactive' for past ones.

Pregnancy-related Observations refer to the EpisodeOfCare with Observation.context.reference
Maternal Preferences	List	Maternal preferences (such as infant nutrition, delivery location) are grouped in a List of which the woman Patient is the subject. The maternal preferences list includes references to Maternal Preference Observations in List.entry.item
Maternal Preference Observations	Observation	Maternal Preference Observations are about the preferences of the woman Patient, who is the subject of these Observations. Maternal Preference Observations refer to the EpisodeOfCare with Observation.context.reference
Childbirth Assistance	Encounter	Childbirth Assistance is modeled as an Encounter. The woman Patient is subject of the Encounter. The place of birth is described in Encounter.class using a ConceptMap to map values to available FHIR codes The Encounter.diagnosis element refers to the Pregnancy (Condition) The Encounter.participant element containts a list of care providers that were present during delivery. Family members and even the woman Patient could also be included in this list. Additional details can be defined at participant level, such as participant type and time of arrival. The latter uses an extension at participant level with a coded list of time of arrival. Childbirth Assistance refers to the EpisodeOfCare with Encounter.EpisodeOfCare.reference
Delivery (Bevalling)	Procedure	Delivery is modeled with Procedure (even for uncomplicated natural births for consistency). Delivery refers to the EpisodeOfCare with Observation.context.reference

Delivery-related Observations use focus extension to point to the delivery Procedure they're about. Delivery-related Observations refer to the EpisodeOfCare with Observation.context.reference
Placenta	BodySite	The placenta is a body structure of the woman Patient and is modeled as a BodySite. The BodySite.patient element refers to the woman Patient.
Placenta-related Observations	Observation	Observations related to the Placenta (such as date/time of birth placenta) use the focus element to refer to the Placenta. The woman Patient is still the subject of the Observation. Placenta-related Observations use focus extension to point to the placenta. Placenta-related Observations refer to the EpisodeOfCare with Observation.context.reference
Birth	Observation	A birth pertains to a delivery Procedure as well as a child, especially in multiple birth where multiple Birth instances point to the same delivery Procedure. A birth also provides the relation between a child and its mother, which is still the subject of the record. Birth uses focus extension to point to the delivery Procedure.

Birth-related Observations use focus extension to point to a birth. Birth-related Observations refer to the EpisodeOfCare with Observation.context.reference
Child	Patient	Child is a separate Patient. Procedure-related Observations use focus extension to point to the child Patient they're about.
Child-related Observations	Observation	Observations such as Apgar score and birthweight pertain to the child Patient, which is the subject of these Observations. Child observations refer to the EpisodeOfCare with Observation.context.reference
Child disorders	Condition	Child disorders such as chromosomal and congenital abnormalities or other problems are conditions. The child is the subject. Child disorders can refer to the EpisodeOfCare with Condition.context.reference A ConceptMap is available to map verification status to accepted FHIR codes
Digital vaginal examination	DiagnosticReport	The digital vaginal examination DiagnosticReport groups Observations related to the digital vaginal examination. The woman Patient is the subject of the report. Digital vaginal examination refers to the EpisodeOfCare with DiagnosticReport.context.reference
Digital vaginal examination Observations	Observation	Observations related to the digital vaginal examination pertain to the woman Patient, who is the subject of the observation. Digital vaginal examination observations refer to the EpisodeOfCare with Observation.context.reference
