Proposed CIMI Reference Model

The proposed Core CIMI Reference Model consists of the following components:

Component Name Description Notes Examples
COMPOSITION A general type for document structure that can contain heterogeneous content This structure is generalized beyond just a document about a single patient. It may also be a definitional artifact targeting a cohort of patients. Hence, it does not specify the subject of the record in the reference model. Discharge summary, History & Physical, Order Set, ECA Rule, Questionnaire
CONTENT Abstract node representing a document content item. Content items may be containers such as a section or a single entry in the record or document. CONTENT should support nested structures such as sections within sections or composite actions in a CDS knowledge artifact. Note that this is an abstract structure and is intended to be further specialized. A section in a document, an orderable item in an order set, a clinical statement.
CONTENT_GROUP Concrete type representing a potentially nested content container structure within a document. Note that the name CONTENT_GROUP rather than SECTION is used in order to support a broader range of document types and content containment structures. A section in a document, an action container in a knowledge document that supports different types of selection behaviors.
ENTRY Concrete type representing a content entry in a document such as a clinical statement in a patient record or a recommended action in a CDS knowledge document. Intended to be specialized in more than one way. In CIMI, ENTRY is the abstract superclass for the STATEMENT class. In CDS, ENTRY may be specialized into the ACTION type of CDS Knowledge Artifacts.
STATEMENT Abstract type for Clinical Statements. This type is the entry point into the CIMI Clinical Statement hierarchy. It must support composite statements such as a composite orderable or a laboratory panel, for instance. Note that this set of statement is partitioned into two concrete types, an indivisible statement and a composite statement. A laboratory result. A laboratory panel.
INDIVISIBLE_STATEMENT Concrete type representing an atomic statement. Statement may extend beyond clinical statement, hence the more general name STATEMENT rather than Clinical Statement. A simple lab result or other quantitative observation.
COMPOSITE_STATEMENT A potentially nested structure that represents a collection of indivisible statements. Based on both CIMI and CDS/CQI requirements for composite statements that may be recursively nested. Lab panels or composite medication orderables such as an OST.
ITEM Abstract type for an item in a CONTENT ENTRY. This set is partitioned into ITEM_GROUP, a recursively nested structure, and ELEMENT. A complex data type. A simple attribute.
ITEM_GROUP A collection of other ITEM_GROUPs or individual ELEMENTS. ITEM_GROUP is used to define new Cluster-types in CIMI Complex data types such as an Address type or an AnatomicalLocation structure.
ELEMENT A simple attribute type with a DATA_VALUE type. Leaf level item typically used to define new simple attributes in an archetype. Observation type, address line, procedure performance date, patient birthdate, etc...
