Verwendung

Dieses Profil beschreibt die Verwendung der FHIR-Ressource Dosage im deutschen Kontext und ist für die allgemeine Interoperabilität konzipiert. Das Profil ist offen gehalten und setzt keine spezifischen Dosierschemata voraus, sondern legt ein „Must Support“ auf alle relevanten Felder. Ziel ist es, eine flexible und breit einsetzbare Abbildung von Dosierungsangaben zu ermöglichen, wie sie in unterschiedlichen Primärsystemen und Anwendungsfällen benötigt wird.

Empfehlung:
Nutzen Sie dieses Profil für alle Anwendungsfälle, in denen Dosierungsinformationen interoperabel ausgetauscht werden sollen. Orientieren Sie sich bei der Umsetzung an den empfohlenen Dosierschemata, um eine konsistente und verständliche Darstellung zu gewährleisten.

Weitere Hinweise und Beispiele zu bewährten Dosierschemata ist unter Unterstützte Dosierungen beschrieben.
