1 Introduction

Go to functional design

This page describes patient's use case for the retrieval of vaccination results, in a personal health environment (PHR) context. Functional specifications are described at the functional design wiki page. The technical specification is described here. HL7 FHIR R4 is used for this purpose.

Note: This implementation guide builds on the general guidelines described in the use case overarching principles.

1.1 Vaccinations

Vaccination results are represented by the Immunization resources. It contains the relevant data elements per single vaccination about the administered vaccination such as DateTime of administration, vaccination indication and pharmaceutical product. The transaction consists of all available administered vaccinations at the XIS. The transactions:

Retrieve vaccination results

2 Actors involved

Persons Systems FHIR Capability Statements
Name Description Name Description Name Description
Patient The user of a personal healthcare environment. PHR Personal health record Verwijzing.png CapabilityStatement: Client Vaccination process client requirements
(Health)care provider The user of a XIS XIS (Healthcare) information system Verwijzing.png CapabilityStatement: Server Vaccination server requirements

3 Use case 1: Retrieve vaccinations

Go to Afsprakenstelsel

This FHIR implementation guide assumes that the PHR system is able to make a connection to the right XIS that contains the patient's information. It does not provide information on finding the right XIS nor does it provide information about security. Moreover, each transaction is performed in the context of a specific authenticated patient, for whose context (token) has been established using the authentication mechanisms described in the 'Afsprakenstelsel'. Each XIS Gateway is required to perform filtering based on the patient associated with the context for the request, so only the records associated with the authenticated patient are returned. For this reason, search parameters should not be included for patient identification.

3.1 Introduction

The retrieve vaccinations transaction is used by the PHR to retrieve vaccinations from a XIS.

3.2 Actors

Transaction group Transaction Actor Role
Retrieve vaccinations(PULL) Retrieve vaccinations request Patient (using a PHR) Request vaccinations from the XIS
Retrieve vaccinations response (Healthcare) provider (using a XIS) Serves vaccinations to the PHR

3.3 Invocations

3.3.1 PHR: request message

The request message represents an HTTP GET parameterized query from the PHR to the XIS.

3.3.1.1 Trigger Events

When the patient(PHR) wants to obtain vaccinations, it issues a retrieve vaccinations request message.

3.3.1.2 Message Semantics

The PHR executes an HTTP GET conform to the FHIR RESTful and search specification against the XIS's Observation endpoint. This search query URL is configurable by the PHR and has the following format:

---> ANDER VOORBEELD CODE HIER???????????????

GET [base]/Observation?category=http://snomed.info/sct|49581000146104{&[parameters]}

The PHR may use, and the XIS shall be capable of processing, the following parameters to configure the search query:

Name Description Examples
date Obtained date/time for the result. If the result was obtained over a period, this parameter should be interpreted as a date that falls in this period. Retrieve all zib LaboratoryTestResults Observation resources that have an effective date greater than 01-01-2010:
GET [base]/Observation?category=http://snomed.info/sct|49581000146104&date=ge2010-01-01

Retrieve all zib LaboratoryTestResults Observation resources that have an effective date within a 2 year period:

GET [base]/Observation?_include=Observation:specimen&category=http://snomed.info/sct|49581000146104date=ge2010-01-01&date=le2011-12-31
category The classification of the type of observation. Retrieve all zib LaboratoryTestResults Observation resources:
GET [base]/Observation?category=http://snomed.info/sct|49581000146104
_include The PHR may request that the XIS returns resources related to the search results, in order to reduce the overall network delay of repeated retrievals of related resources. Retrieve all zib LaboratoryTestResults Observation resources and include Specimen information in the search results:
GET [base]/Observation?_include=Observation:specimen&category=http://snomed.info/sct|49581000146104
3.3.1.2.1 Expected Actions

The XIS shall process the query to discover Observation resources that match the search parameters given.

3.3.2 XIS: response message

The XIS returns an HTTP Status code appropriate to the processing as well as a FHIR Bundle including the matching observation information.

3.3.2.1 Trigger Events

The XIS completed processing of the retrieve vaccinations request message.

3.3.2.2 Message Semantics

The returned data to the PHR should conform to the HCIMs and their associated profiles listed in the table below. The resources in the response message SHALL be a valid instance of these profiles. All resources SHALL include their related profile canonical URL in the meta.profile element in order to show compliance.

Zib name NL Zib name EN FHIR Resource

Zorgaanbieder HealthcareProvider Organization http://fhir.nl/fhir/StructureDefinition/nl-core-organization
LaboratoriumUitslag LaboratoryTestResult Observation http://nictiz.nl/fhir/StructureDefinition/zib-LaboratoryTestResult-Observation

3.3.2.3 Expected Actions

The PHR shall process the results according to application-defined rules. The PHR should be robust as the response may contain observation and specimen resources that match the query parameters.

4 Use case: retrieve laboratory results DiagnosticReport

Go to Afsprakenstelsel

This FHIR implementation guide assumes that the PHR system is able to make a connection to the right XIS that contains the patient's information. It does not provide information on finding the right XIS nor does it provide information about security. Moreover, each transaction is performed in the context of a specific authenticated patient, for whose context (token) has been established using the authentication mechanisms described in the 'Afsprakenstelsel'. Each XIS Gateway is required to perform filtering based on the patient associated with the context for the request, so only the records associated with the authenticated patient are returned. For this reason, search parameters should not be included for patient identification.
