Uses for this model

This model can be used as an enterprise view of healthcare for designing the logical models and subsequent platforms for healthcare information systems.

The model assists in understanding how healthcare is organised so provides business analysts with a starting point for their own analysis.

Getting started

The model has been structured into topics to group related concepts together.

A useful starting point to help understand this model is to look at a specific topic, such as the concepts concerned with the planning of healthcare for a person or to view a concept, such as the care plan concept.

If you are looking for a particular concept you can search the model. The search covers term names, deprecated names, alternative names, the definition of the concepts, notes and examples of use.

The underpinning standard

The model shared through this site conforms with the International Standard ISO 13940:2015 - A System of Concepts for the Continuity of Care published by the International Organization for Standardization (ISO).

This standard succeeds the European Standard EN 13940, published as a European Norm in 2007 by the European Committee for Standardization (CEN) . That European standard focused on basic concepts necessary for healthcare.  The International Standard represents a significant revision, introducing concepts for healthcare processes and broadening applicability.

Both standards provide a concept model in order to graphically describe a concept system within the field of health informatics. This description is intended to clarify the relationships between the concepts and illustrate some of their definitions. The other purpose is to let a concept modelling tool set up a data base organising the concept system, in order to keep track of its concepts and relationships, as well as check its consistency.

Information modelling has the purpose of organising the information objects, each one representing knowledge about a concept. There is however additional information in an information model about the properties of the information objects, shown as attributes to the objects and operations describing behaviour of the objects.  These attributes are not included in the concept models.

The model is graphically represented using Universal Modelling Language (UML) notation with textual definitions, notes and examples.
