1 Introduction
This is the implementation guide (IG) for the information standard Medication Process 9 (MP9) version 3.0.0-beta.3 for patient use cases (MedMij) using the HL7® FHIR® standard. The MP9 standard for MedMij is described in this functional specification and further specified here using FHIR version R4. This implementation guide assumes that the reader is familiar with both the functional specification of both MP9 and MedMij and this version of FHIR.
This document is a specification of FHIR Implementation Guide Medication Process 9, only applicable to the patient use cases. The guidelines as specified in the MedMij FHIR Implementation Guide apply. This document extends the general FHIR Implementation Guide with the specification of the 'Afsprakenstelsel'.
This IG first describes the boundaries and relationships where they differ between the MP9 and MedMij IG, after which the implementation is described per relevant transaction.
2 Boundaries and relationships
Both the MP9 Boundaries and relationships and the MedMij Overarching principles apply. The following sections highlight the points where these two documents contradict and provides guidance on which principles to follow.
2.1 'Use cases' or 'transactions'
Where MP9 uses the term 'transaction', MedMij generally uses the term 'use case'. On this page, the terms are used interchangeable.
2.2 Patient identification
Where MP9 describes the use of patient.identifier search parameters, the MedMij use cases use the authentication method outlined by the MedMij 'Afsprakenstelsel', using Oauth2 tokens.
3 Transactions
This section describes the FHIR implementation of the Retrieve and Serve Medication Data transactions (for MedMij) listed in the functional specification. Each transaction hyperlinks to the functional definition in an ART-DECOR publication. The ART-DECOR publication details which data elements are expected to be supported (cardinality and conformance).
3.1 Medication data (Retrieve/Serve)
The retrieve medication data transaction is used by the client to retrieve medication data from a server. The client can retrieve its desired information by searching for specific medication building blocks.
| Transaction group | Transaction | Actor | System role | FHIR CapabilityStatement |
|---|---|---|---|---|
| Medication data (PULL) | Retrieving medication data | Client | MP-MGR | CapabilityStatement Retrieve/serve medication data (MedMij) |
| Serving medication data | Server | MP-MGB |
3.1.1 Retrieve (request message)
When a patient or healthcare professional wants to obtain all medication data or specific parts matching various parameters, they issue a retrieve medication data request message. This message uses the HTTP GET method parameterized query against the server's medication FHIR endpoints. These endpoints can be one of the following:
- MedicationRequest
- MedicationDispense
- MedicationStatement
- MedicationAdministration
The search interaction is performed by an HTTP GET conform the FHIR search specification, as shown below. This URL is configurable by the client by configuring the search query. Multiple request messages may be needed to retrieve all desired information.
GET [base]/[type]{?[parameters]}

However: all resources referenced per literal reference SHALL be resolvable per the Nictiz IG. |

- ↑ 1,0 1,1 1,2 The search parameter consists of a custom FHIR search parameter not represented in the FHIR specification. Note that for
MedicationRequest.categoryandMedicationStatement.categorya core search parameter is available, hence no custom one is needed in those cases. - ↑ Chained search parameter: searches the medicationReference required in each building block for its
.code. - ↑ For the MedicationRequest and MedicationDispense resource types, the
period-of-useparameter searches on the ext-TimeInterval.Period extension which may include the ext-TimeInterval.Duration extension. For the MedicationStatement resource type, the parameter modifies the core search parameter on.effectiveto include the ext-TimeInterval.Duration extension that may be present.
