General Information

MetaHub

The ‘MetaHub’ component is introduced to support the interconnection between ‘Hubs’. This component is accessible to ‘recognized’ hubs. The word ‘hub’ denotes the kernel of a ‘recognized’ regional or sub regional health network.

The main purpose of the MetaHub is to allow a hub to know where it can find information about a patient outside of its network. More precisely, the MetaHub simply provides the list of hubs that have information about a patient. It is not the MetaHub’s role to know where, within a (sub)regional health network, the information is stored.

The MetaHub is thus more a ‘locator service’ than a ‘routing component’: there are no ‘document’ exchanges transiting throughout the component. MetaHub v2 also allows the hubs to consult and manage the registration of patient consents and exclusions1. A major feature is that the hubs themselves feed the MetaHub. See figure below.

KMEHR

This service is a ‘KMEHR-based’ WS. We thus strongly recommend consulting the documentation related to the KMEHR normative elements. The KMEHR site aims to offer a central point for the documentation of the KMEHR normative elements.

The three following generic elements are, in particular, essentials to build the request and the reply of eHealth MetaHub WS.

cd : This is the key element used to code information: this section is completely based on the description from the KMEHR standard, as can be found on: https://www.ehealth.fgov.be/standards/kmehr/en/page/key-elements#cd
id: This element is used to uniquely identify key elements like request, response of the WS, patient, HCParty. It can also be used to specify any unique identifier: this section is completely based on the description from the KMEHR standard, as can be found on: https://www.ehealth.fgov.be/standards/kmehr/en/page/key-elements#id
HC Party: The hcparty element is a generic element that aims to represent any kind of healthcare party: organization, physician, medical specialty, or even IT systems: this section is entirely based on the description from the KMEHR standard, as can be found on: https://www.ehealth.fgov.be/standards/kmehr/en/page/hcparty

Additional Information	If provided INSS and support card number are not submitted to status validation (Hub Third trusted party)
Comments	A link between a patient and a hub indicates that at least a transaction is declared within the hub about the patient. A patient link can be declared before the registration of a patient’s consent. However, if there is no active consent for the patient in the system, the patient-hub link will not be returned by the getPatientLinks service. It is only possible to declare a patient link for the hub that sends the request. The hub is identified in the sender of the request and the coherence is checked with the technical identification and authentication system.
