FHIR Implementation Guide: Vaccinations 0.1.0

|
Draft version of the FHIR IG for Vaccinations. Currently in development and therefore not yet suitable for implementation. The draft version of the functional design can be found here. |

This version will eventually be tested in a proof of concept (PoC) and should not be used outside this PoC. The repository containing the FHIR conformance materials can be found on GitHub and Simplifier and the functional design can be found [here]. For questions regarding the contents of this information standard, please create a ticket in Nictiz BITS. For PoC (and PROVES) related questions, contact Victor Teunissen on victor.teunissen@vzvz.nl. |
1 Introduction
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. This use case consists of enabling a patient to view his own administered vaccinations in a PHR. 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:
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 |  {}
|
Vaccination process client requirements |
| (Healthcare) provider | The user of a XIS | XIS | (Healthcare) information system | {}
|
Vaccination server requirements |
3 Use case 1: Retrieve vaccinations
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:
GET [base]/immunization
The PHR may use, and the XIS shall be capable of processing, the following parameters to configure the search query:
| Description | Examples |
|---|---|
| Retrieve all zib Immunization resources in the search results: | GET [base]/immunization |
Alternatively an operation may be defined that returns a bundle with the list of immunization resources and a patient resource.
3.3.1.2.1 Expected Actions
The XIS shall process the query to retrieve Immunization 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.

MedMij uses the FHIR Packaging mechanism. This conveniently bundles all profiles, terminology, example material and other conformance resources you need into a single archive, which can be downloaded or installed using the appropriate FHIR tooling. This version of the information standard uses the following packages:
Note: packages use Semantic Versioning. Other versions can be used at will as long as they have the same major.minor number or a minor number higher than the stated version. |

3.3.2.3 Expected Actions
The PHR shall process the results according to application-defined rules. The PHR should contain all the resources that match the query parameters.
