Introduction

Go to functional design

This page describes a patient's use case, in a personal health record (PHR) context, for exchanging allergy and intolerance data. Functional specification of this use case is described in the functional design wiki pages.

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

Actors involved

Name Description Name Description Name Description

Use case: Retrieve AllergyIntolerance information

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.

Introduction

The retrieve AllergyIntolerance transaction is used by the PHR to retrieve allergy and intolerance information from the XIS.

Actors

Transaction group Transaction Actor Role
Retrieve AllergyIntolerance(PULL) Retrieve AllergyIntolerance request Patient (using a PHR) Request allergy and intolerance information from the XIS
Retrieve AllergyIntolerance response Healthcare professional (using a XIS) Serves allergy and intolerance information to the PHR

Invocations

PHR: request message

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

Trigger Events

When the patient(PHR) wants to obtain allergy and intolerance information, it issues a retrieve AllergyIntolerance request message.

Message Semantics

The PHR executes an HTTP GET conform to the FHIR RESTful and search specification against the XIS's AllergyIntolerance endpoint. This search query has the following format.

GET [base]/AllergyIntolerance
Expected Actions

The XIS shall process the query to discover AllergyIntolerance resources that match the patient in the context.

XIS: response message

The XIS returns an HTTP Status code appropriate to the processing as well as a FHIR Bundle including the allergy and intolerance information.

Trigger Events

The XIS completed processing of the Retrieve AllergyIntolerance request message.

Message Semantics

The returned data to the PHR should conform to the HCIMs and 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.

Expected Actions

The PHR processes the results according to application-defined rules. The PHR should be robust as the response may contain AllergyIntolerance information resources as mentioned in the former section.

Use case: Retrieve AllergyIntolerance612ToFHIRConversion

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.

Introduction

A PHR uses the retrieve AllergyIntolerance612ToFHIRConversion transaction to retrieve "6.12-based" allergy and intolerance information from a XIS. This information is based on a conversion from the 6.12 information standard. The XIS converts the requested information by a PHR to FHIR-resources.

The 6.12 AllergyIntolerance information is originally exchanged in HL7v3-messaging format. For interested readers the HL7v3-specifications can be found in the 6.12 template for 'potential contraindications'.

However, please note that it is not necessary for a PHR to have knowledge of the HL7v3-format to implement this use case.

Expected Actions

The XIS shall process the query to discover AllergyIntolerance resources that are part of the 6.12 information standard and match the patient in the context.

XIS: response message

The XIS returns an HTTP Status code appropriate to the processing as well as a FHIR Bundle including the appropriate allergy and intolerance information.

Trigger Events

The XIS completed processing of the Retrieve AllergyIntolerance request message.
