Where such defaulting occurs, rule enforcement should allow for the variation between administrative and biological, chromosomal and other gender aspects. For example, an alert about a hysterectomy on a male should be handled as a warning or overridable error, not a 'hard' error.

| description | Dieses Profil spezifiziert die Minimalanforderungen für die Bereitstellung von administrativen Patientendaten im Rahmen des Bestätigungsverfahrens der gematik. ### Motivation Der Austausch administrativer Patientendaten ist eine der grundlegenden Funktionalitäten beim Datenaustausch in der klinischen Versorgung. In FHIR werden sämtliche klinischen Ressourcen durch Verlinkung auf die Ressource 'Patient' in einen Patientenkontext gestellt. Die Herstellung des korrekten Patientenkontextes durch Suchen der Patientenressource anhand von Eigenschaften wie Aufnahmenummer, Name oder Geburtsdatum, die Anzeige der zutreffenden Suchergebnisse und der Auswahl bzw. Bestätigung des richtigen Datensatzes durch den Anwender steht am Beginn der meisten klinischen Workflows. ### Kompatibilität Für das Profil ISIKPatient wird eine Kompatibilität mit folgenden Profilen angestrebt; allerdings kann nicht sichergestellt werden, dass Instanzen, die gegen ISIKPatient valide sind, auch valide sind gegen: * [Profil KBV_PR_Base_Patient der KBV Basisprofile](https://fhir.kbv.de/StructureDefinition/KBV_PR_Base_Patient) * [Profil Patient im International Patient Summary (IPS)](https://hl7.org/fhir/uv/ips/StructureDefinition-Patient-uv-ips.html) * [Profil Patient der MI-Initiative](https://www.medizininformatik-initiative.de/fhir/core/modul-person/StructureDefinition/Patient) Hinweise zu Inkompatibilitäten können über die [Portalseite](https://service.gematik.de/servicedesk/customer/portal/16) gemeldet werden. | This profile specifies how the HL7 FHIR Patient resource should be used for conveying commonly used concepts in the European context. |
