Über die Extension

Motivation

Diese Extension enthält einen Wahrheitswert darüber, ob der Verordnende ein anderes Arzneimittel verordnet hat als angefragt wurde.

Sollte der Arzt nach Prüfung der Rezeptanforderung etwas anderes verordnen, als der Anfragende angefragt hat, ist das Feld valueBoolean mit true zu setzen. So kann das System des Anfragenden den Nutzer explizit darauf hinweisen, dass die Antwort von der Anfrage abweicht. Die Extension kann automatisch vom PVS gesetzt werden, wenn der Verordnende eine Angabe in dem Rezept ändert.

To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
