   "description": "Patient Merge Subscription  \n### Motivation\n\nSubscription ist eine FHIR Ressource, um als Client-System Benachrichtigungen über Events auf dem FHIR Server anzufragen. Der Subscription Mechanismus in FHIR R4 ist nicht geeignet, um alle relevanten Events (hier im Speziellen das Mergen von Patienten) zu unterstützen. Daher basiert das ISiK Subscription-Profil auf dem [Subscriptions R5 Backport Profil von HL7](https://hl7.org/fhir/uv/subscriptions-backport/STU1.1/StructureDefinition-backport-subscription.html).\n\nSiehe auch: {{pagelink:Patient-merge, text:Use Case Patient-merge}}\n\nUm als Subsystem über ein Patienten-Merge-Event informiert zu werden, KANN der FHIR Subscription Mechanismus gemäß des [Subscriptions R5 Backport IGs von HL7](https://hl7.org/fhir/uv/subscriptions-backport/STU1.1/index.html) genutzt werden.\n\n### Kompatibilität\n\nDas Profil PatientMergeSubscription basiert auf dem [Backport-Subscription Profil](https://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition-backport-subscription.html).  \nDer [SubscriptionStatus](https://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition-backport-subscription-status-r4.html), sowie das [Subscription Notification Bundle](https://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition-backport-subscription-notification-r4.html) werden unverändert direkt aus dem [Subscriptions R5 Backport IG](https://hl7.org/fhir/uv/subscriptions-backport/index.html) genutzt.  \n\nHinweise zu Inkompatibilitäten können über die [Portalseite](https://service.gematik.de/servicedesk/customer/portal/16) gemeldet werden.",
