MedMij FHIR Implementation Guide basic GGZ data
Work in progress - See official publication here.
The page describes the FHIR requirements for exchanging GGZ information between the patients and healthcare providers in the context of MedMij.
Note: This implementation guide builds on the general guidelines described in the use case overarching principles.
2 Actors involved
|Actors||Systems||FHIR Capability Statements|
|Patient||The user of a personal healthcare environment.||PHR||Personal health record||CapabilityStatement: Client||FHIR Client requirements|
|Healthcare professional||The user of a XIS||XIS||Healthcare information system||CapabilityStatement: Server||FHIR Server requirements|
3 Boundaries and Relationships
The GGZ use case has similarities and differences with other use cases such as the BgZ, Medication Process, Vital Signs, GP Patient Data and Lab Results. These use cases use much of the same HCIM based FHIR profiles for exchanging information. Wherever possible every attempt is made to re-use the profiles as used in the BgZ. The GGZ use case also has unique profiles compared to the aforementioned use cases. In addition, it has a CareTeam profile without an underlying HCIM. A second thing to note is that while the selection criteria of certain sections like procedure do not match with the BgZ or other use cases, this does not affect the profiles in use. For example, it is irrelevant for the response profile for procedures if you request ' surgical procedures' or 'every procedure'.
4 Use case: retrieve GGZ information
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.
4.1 PHR: request message
The PHR system requests the patients GGZ information using individual search interactions. The BgGGZ consists of multiple FHIR resources with certain constraints. To obtain the patient's BgGGZ, the client can use multiple individual search operations based on specified search queries. The interactions are performed by an HTTP GET as shown:
The table below shows in the first three columns the HCIM name in Dutch, in English and what HCIM content is requested. The last column shows the FHIR search queries to obtain this information. These queries and expected responses are based on profiles listed in this section.

4.2 Server - XIS
The returned data to the PHR should conform to the profiles listed in #List_of_profiles.
The following operation is needed for this use case.
lastn query meets the common need for searching for the most recent or last n=number of observations for a subject. For example, retrieving the last 5 temperatures for a patient to view trends or fetching the most recent laboratory results or vital signs. The link will provide more detailed information and examples regarding this operation.
The FHIR STU3 specification is vague regarding the sorting mechanism of
lastn. In FHIR R4 however, this has been clarified and can be read as follows: when using
effective[x] element is used for sorting of Observations, sorted from most recent to the oldest.
4.4 List of profiles
The profiles represent their entire respective HCIM and are applicable in a broader context than the exchange of GGZ information.
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.
Due to legislation (the 'Wet verplichte ggz' (Wvggz)) HCIM FreedomRestrictingMeasures-v3.1 (release 2017) has become obsolete. Therefore, this version of the BgGGZ will not require the use and exchange of this HCIM.
* LegalStatus is a single concept of the HCIM FreedomRestrictingMeasures and does not represent a complete HCIM yet. This concept will become an independent HCIM in a future release of the HCIM.
