Health IT Ontology

comment: The Health IT Ontology (HITO) allows systematically describing application systems and software products in health IT.
abstract: The Health IT Ontology (HITO) allows systematically describing application systems and software products in health IT. Our motivation is that information management professionals have a strong need to share and compare knowledge about health IT in several situations. These situations are, among others, to describe the components of a health information system as part of its strategic or operational management, to select a new software product, to learn about available evidence regarding an application, or to hire or train health IT specialists.

source: interoperability-healthcare
comment: Interoperability in general is the ability of two or more components to exchange information and to use the information that has been exchanged. Standards provide a common language and a common set of expectations that enable interoperability between systems and/or devices. In order to seamlessly digest information about an individual and improve the overall coordination and delivery of healthcare, standards permit clinicians, labs, hospitals, pharmacies and patients to share data regardless of application or market supplier. Interoperability standards in the context of HITO also include interoperability frameworks such as IHE.
comment: Interoperabilität ist im Allgemeinen die Fähigkeit von zwei oder mehr Komponenten, Informationen auszutauschen und die ausgetauschten Informationen zu nutzen. Normen bieten eine gemeinsame Sprache und eine Reihe gemeinsamer Erwartungen, die die Interoperabilität zwischen Systemen und/oder Geräten ermöglichen. Um Informationen über eine Person nahtlos zu verarbeiten und die Gesamtkoordination und -bereitstellung der Gesundheitsversorgung zu verbessern, ermöglichen Normen Ärzten, Labors, Krankenhäusern, Apotheken und Patienten den Austausch von Daten unabhängig von der Anwendung oder dem Marktanbieter. @de
