5 CDA Design

NOTE: The definitive description of HL7 V3 model refinement, R-MIM development and interpretation can be found here.

The CDA R-MIM POCD_RM000040UV02 can be found here: Link to wide graphic (opens in a new window)

A CDA document is comprised of a header and a body. The header identifies and classifies the document; provides information on authentication, the encounter, the patient, and the provider; and sets the context for the document as a whole. The body contains the clinical report, and is conceptually divided up into nested sections, each containing a narrative block to be rendered along with structured entries and external references.

5.1 Clinical Document

The ClinicalDocument class is the entry point into the CDA R-MIM, and corresponds to the <ClinicalDocument> XML element that is the root element of a CDA document instance. This section will outline the CDA Document's physical design, first in the header and then the body.

A CDA document is logically broken up into a CDA Header and a CDA Body. The CDA Header is comprised of ClinicalDocument attributes, participants, and act relationships. The CDA Body is the target of the ClinicalDocument component act relationship.

5.2 Header

The purpose of the CDA header is to enable clinical document exchange across and within institutions; facilitate clinical document management; and facilitate compilation of an individual patient's clinical documents into a lifetime electronic patient record. The CDA header sets the context for the document as a whole and the context for understanding the content contained in the document.

5.2.1 ClinicalDocument

The CDA schema was produced by serialization of the CDA model. The starting point for his serialization was the ClinicalDocument class. The ClinicalDocument is the root element in a CDA document instance.

5.2.1.1 ClinicalDocument Attributes

This section describes attributes defined in the ClinicalDocument class.

The table below identifies the attributes of ClinicalDocument. For each item, the name is provided, along with the data type, wire cardinality*, code bindings, and binding type or strength. The links allow will access to the item's definition, data type definition, and when appropriate, the concept domain or value set used with the item.

Table X: ClinicalDocument Attributes

Note*: The wire cardinality represents is the effective cardinality of an element, taking into account 1.3.1 Recipient Responsibilities, relaxation of the requirement to exchange fixed and defaulted values. The logical cardinality expressed in the CDA Hierarchical Description is still present, but assumed by the recipient, not imposed on the wire format of an instance of a CDA document.

ClinicalDocument.classCode

The ClinicalDocument.classCode in the CDA model is fixed to "DOCCLIN". As a result, in the CDA R2.1 Schema, the ClinicalDocument/@classCode has been fixed to "DOCCLIN".

As noted in section 1.3.1 Recipient Responsibilities, fixed and default values asserted in this standard are not required to be present in CDA document instances. However, CDA Implementation Guides can still require them via conformance statements.

Table X: Fixed ClinicalDocument.classCode
Code	Display Name
DOCCLIN	clinical document
Code System: ActClass (HL7) Code System OID: 2.16.840.1.113883.5.6

ClinicalDocument.moodCode

The ClinicalDocument.moodCode in the CDA model is fixed to "EVN" or event mood to indicate that this is documentation of a past service. In the CDA R2.1 Schema, the ClinicalDocument/@moodCode has been fixed to "EVN".

Table X: Fixed ClinicalDocument.moodCode
Code	Display Name
EVN	event
Code System: ActMood (HL7) Code System OID: 2.16.840.1.113883.5.1001

The ClinicalDocument class inherits various attributes from the InfrastructureRoot class of the RIM, including ClinicalDocument.templateId and ClinicalDocument.typeId which are discussed here. All CDA classes inherit from infrastructureRoot, which is discussed in Section (link here).

ClinicalDocument.typeId

ClinicalDocument.typeId is a technology-neutral explicit reference to this CDA, Release Two specification, and must be valued as follows: ClinicalDocument.typeId.root = "2.16.840.1.113883.1.3" (which is the OID for HL7 Registered models); ClinicalDocument.typeId.extension = "POCD_HD000040UV20" (which is the unique identifier for the CDA, Release Two Hierarchical Description).

ClinicalDocument.templateId

When a templateId is present in a CDA element, it signals the imposition of a set of template-defined constraints for that element. The templateId is one of the infrastructure attributes added to all CDA classes. It has only been displayed for ClinicalDocument, but is present in all CDA classes, where it can be used to identify constraints defined in an external Implementation Guide template. See 4.3.2 Template Versioning.

ClinicalDocument.id

Represents the unique instance identifier of a clinical document.

ClinicalDocument.code

The code specifying the particular kind of document (e.g. History and Physical, Discharge Summary, Progress Note). The value set is drawn from LOINC, and has a CWE coding strength.

Within the LOINC database, beginning with version 2.09, May 2003, document type codes are those that have a value of "DOC" in the Scale component. This subset of LOINC is described in the appendix (see LOINC Document Codes).

ClinicalDocument.title

Represents the title of the document. It's commonly the case that clinical documents do not have a title, and are collectively referred to by the display name of ClinicalDocument.code (e.g. a "consultation" or "progress note"). Where these display names are rendered to the clinician, or where the document has a unique title, the ClinicalDocument.title component should be used. In the example document in the appendix (see Sample Document), the value of ClinicalDocument.title = "Good Health Clinic Consultation Note".

ClinicalDocument.effectiveTime

Signifies the document creation time, when the document first came into being. Where the CDA document is a transform from an original document in some other format, the ClinicalDocument.effectiveTime is the time the original document was created. The time when the transform occurred is not currently represented in CDA.

ClinicalDocument.ConfidentialityCode

Confidentiality is a required contextual component of CDA, where the value expressed in the header holds true for the entire document, unless overridden by a nested value (as further described in CDA Context). A best practice for clinical documents is to assert the highest level of confidentiality present within a document at the header level.

Table X: Value set for ClinicalDocument.confidentialityCode
x_BasicConfidentialityKind [2.16.840.1.113883.1.11.16926] (OPEN)
Code	Display Name	Code	Display Name
N	normal	R	restricted
V	very restricted
Code System: Confidentiality (HL7) Code System OID: 2.16.840.1.113883.5.25

* The codeSystem value is included here because confidentialityCode is of type CE, and therefore must carry both a code and a codeSystem.

ClinicalDocument.languageCode

Specifies the human language of character data (whether they be in contents or attribute values). The values of the attribute are language identifiers as defined by the IETF (Internet Engineering Task Force) RFC 3066 for the Identification of Languages, ed. H. Alvestrand. 1995, which obsoletes RFC 1766. The HL7 code system for these values is "2.16.840.1.113883.6.121". Language is a contextual component of CDA, where the value expressed in the header holds true for the entire document, unless overridden by a nested value (as further described in CDA Context).

ClinicalDocument.setId

Represents an identifier that is common across all document revisions.

ClinicalDocument.versionNumber

A string used to represent the version of the document. For CDA R2.1 we use the ST data type as defined in the HL7 Version 3 Standard: XML Implementation Technology Specification - Wire Format Compatible Release 1 Data Types, Release 1 (XML ITS R2B). We have adopted, for all versionNumber references in CDA R2.1, this data type because it supports an @value attribute, and can support wire format compatibility with the versionNumber in CDA R2.0.

ClinicalDocument.copyTime (Deprecated)

Represents the time a document is released (i.e. copied or sent to a display device) from a document management system that maintains revision control over the document. Once valued, it cannot be changed. The intent is to give the viewer of the document some notion as to how long the document has been out of the safe context of its document management system.

Included for backwards compatibility with CDA, Release One. ClinicalDocument.copyTime has been deprecated because it is not part of the document at the time it is authenticated, but instead represents metadata about the document, applied at some variable time after authentication. Further use is discouraged.

5.2.2 Header Participants

This section describes classes related to the root ClinicalDocument class via a Participation.

5.2.2.1 authenticator

Represents a participant who has attested to the accuracy of the document, but who does not have privileges to legally authenticate the document. An example would be a resident physician who sees a patient and dictates a note, then later signs it. (See also legalAuthenticator)

A clinical document can have zero to many authenticators. Both authentication and legal authentication require that a document has been signed manually or electronically by the responsible individual.

Code System: ParticipationSignature (HL7) Code System OID: 2.16.840.1.113883.5.89

Note: CDA Release One represented either an intended ("X") or actual ("S") authenticator. CDA Release 2 and 2.1 only represents an actual authenticator, so usage of "X" and "I" are deprecated.

authenticator.signatureText

A new attribute, SignatureText has been added to authenticator. The signature can be represented either inline or by reference according to the ED data type. Typical cases are:

Paper-based signatures: the ED data type may refer to a document or other resource that can be retrieved through an electronic interface to a hardcopy archive.
Electronic signature: this attribute can represent virtually any electronic signature scheme.
Digital signature: this attribute can represent digital signatures by reference to a signature data block that is constructed in accordance to a digital signature standard, such as XML-DSIG, PKCS#7, PGP, etc.

5.2.2.1.1 AssignedEntity

An authenticator is a person in the role of an assigned entity (AssignedEntity class). An assigned entity is a person assigned to the role by the scoping organization. The entity playing the role is a person (Person class). The entity scoping the role is an organization (Organization class). (See here for a description of "player" and "scoper" role associations.)

The author.functionCode is bound to the concept domain ParticipationFunction, which is used to specify the exact function an actor had in a service in all necessary detail. This domain may include local extensions (Open).

In some cases, the role or function of the author is inherent in the ClinicalDocument.code, such as where ClinicalDocument.code is "Medical Student Progress Note". The role of the author can also be recorded in the Author.functionCode or AssignedAuthor.code attribute. If either of these attributes is included, they should be equivalent to or further specialize the role inherent in the ClinicalDocument.code (such as where the ClinicalDocument.code is simply "Physician Progress Note" and the value of Author.functionCode is "rounding physician"), and shall not conflict with the role inherent in the ClinicalDocument.code, as such a conflict would constitute an ambiguous situation.

author.contextControlCode

The author.contextControlCode is fixed to "OP". It means that the author will replace the set of author participations that have propagated from ancestor Acts, and will itself be the only author to propagate to any child Acts that allow context to be propagated.

5.2.2.7 informationRecipient

informationRecipient

Represents a recipient who should receive a copy of the document.

NOTE: The information recipient is an entity to whom a copy of a document is directed, at the time of document authorship. It is not the same as the cumulative set of persons to whom the document has subsequently been disclosed, over the life-time of the patient. Such a disclosure list would not be contained within the document, and it is outside the scope of CDA.

5.2.2.8 legalAuthenticator

Represents the participant(s) who has legally authenticated the document.

CDA R2.1, now supports [0..*] legal authentications. This enhancement was put into CDA to support the sharing of medical documents needing to take more than one legal authentication signature.

The CDA is a standard that specifies the structure of exchanged clinical documents. In the case where a local document is transformed into a CDA document for exchange, authentication occurs on the local document, and that fact is reflected in the exchanged CDA document. A CDA document can reflect the unauthenticated, authenticated, or legally authenticated state. The unauthenticated state exists when no authentication information has been recorded (i.e., it is the absence of being either authenticated or legally authenticated).

Both authentication and legal authentication require that a document has been signed manually or electronically by the responsible individual. A legalAuthenticator has a required legalAuthenticator.time indicating the time of authentication, and a required legalAuthenticator.signatureCode, indicating that a signature has been obtained and is on file.

legalAuthenticator.signatureText

A new attribute, SignatureText has been added to legalAuthenticator. The signature can be represented either inline or by reference according to the ED data type. Typical cases are:

Paper-based signatures: the ED data type may refer to a document or other resource that can be retrieved through an electronic interface to a hardcopy archive.
Electronic signature: this attribute can represent virtually any electronic signature scheme.
Digital signature: this attribute can represent digital signatures by reference to a signature data block that is constructed in accordance to a digital signature standard, such as XML-DSIG, PKCS#7, PGP, etc.

5.2.2.11 recordTarget

recordTarget

The recordTarget identifies the specified patient's medical record that the document belongs to.

A clinical document typically has exactly one recordTarget participant. In the uncommon case where a clinical document (such as a group encounter note) is placed into more than one patient chart, more than one recordTarget participant can be stated.

Note: The recordTarget(s) of a document are stated in the header and propagate to nested content, where they cannot be overridden. However, the patient(s) specified by the recordTarget are assumed to be the default subjects of the clinical document. Unlike the recordTarget, which can not be overridden, the patients or subjects propagate to nested components, and can be overridden at the section or entry level. (see See CDA Context).

5.2.2.13 Participant Scenarios

Several CDA Header participations can be played by the same person. In such cases, the person should be identified as the player for each appropriate participation. For instance, if a person is both the author and the authenticator of a document, the CDA Header should identify that person as both the author participant and the authenticator participant.

On other occasions, CDA Header participants are played by different people. The following table shows a number of scenarios and the values for various participants.

Table X: CDA participation scenarios

Technical note: CDA R2.0 design assumes that ClinicalDocument was the source for all typecodes found in relatedDocument, ("APND", "RPLC" and "XFRM"). For "APND" and "RPLC" this is correct, however for "XFRM", the RIM definition indicates that "it is used when the target Act is a transformation of the source Act...". This technically is an error in CDA R2.0's design, which normally should have required the use of inversionInd to establish the ClinicalDocument as the target and the ParentDocument as the source for the "XFRM" relation.

As a result, in CDA R2.1 when "XFRM" is assigned to the relatedDocument.typeCode, the associated inversionInd will be assumed to be fixed to true, but will not be required to be present in the instance document. In all other cases, "APND", "RPLC" the associated inversionInd will not be present and will be assumed to be false. This enables wire format compatibility between CDA R2.0 and CDA R2.1, and ensures proper interpretation of the "XFRM" ActRelationshipType code.

5.2.3.1.2 ParentDocument

The ParentDocument identifies and optionally provides a reference to the original document serving as the source for the current document revision, addendum or transformation.

ParentDocument.id

The ParentDocument.id is a required identifier, which uniquely identifies the parent document.

ParentDocument.code

The code specifying the particular kind of document (e.g. History and Physical, Discharge Summary, Progress Note). The value set is drawn from LOINC, and has a CWE coding strength.

ParentDocument.text

ParentDocument.text is modeled as an ED data type - allowing for the expression of the MIME type of the parent document. It is not to be used to embed the related document, and thus ParentDocument.text.BIN is precluded from use.

ParentDocument.setId

Optional setID for the parent document.

ParentDocument.versionNumber

Optional versionNumber of the parent document.

Additional Information on Document Identification, Revisions, and Addenda

A clinical document can be replaced by a new document and/or appended with an addendum.

A replacement document is a new version of the parent document. The parent document is considered superseded, but a system may retain it for historical or auditing purposes. The parent document being replaced is referenced via act relationship relatedDocument, where relatedDocument.typeCode is set to equal "RPLC" (for "replaces"). An example is a report found to contain an error that is subsequently replaced by the corrected report.

An addendum is a separate document that references the parent document, and may extend or alter the observations in the prior document. The parent document remains a current component of the patient record, and the addendum and its parent are both read by report recipients. The parent report (represented by the ParentDocument class) being appended is referenced via act relationship relatedDocument, where relatedDocument.typeCode is set to equal "APND" (for "appends").

Every CDA document must have a unique ClinicalDocument.id, and thus the replacement or addendum documents each have ClinicalDocument.id that is different from that of the parent document.

CDA documents may also contain a ClinicalDocument.setId and a ClinicalDocument.versionNumber, which together support a document identification and versioning scheme used in some document management systems. In this scheme, all documents in a chain of replacements have the same ClinicalDocument.setId and are distinguished by an incrementing ClinicalDocument.versionNumber. The initial version of a document gets, in addition to a new unique value for ClinicalDocument.id, a new value for ClinicalDocument.setId, and has the value of ClinicalDocument.versionNumber set to equal "1". A replacement document gets a new globally unique ClinicalDocument.id value, and uses the same value for ClinicalDocument.setId as the parent report being replaced, and increments the value of ClinicalDocument.versionNumber by 1. (Note that version number must be incremented by one when a report is replaced, but can also be incremented more often to meet local requirements.)

These relationships are illustrated in the following exhibit "Document Identification, Revisions, and Addenda Scenarios". Typical scenarios are:

A simple relacement (e.g. ClinicalDocument.id "1.2.345.6789.266" replacing ClinicalDocument.id "1.2.345.6789.123")
A simple append (e.g. ClinicalDocument.id "1.2.345.6789.456" appends ClinicalDocument.id "1.2.345.6789.123").

More complex scenarios that might be anticipated include:

[1] replacement of an addendum (e.g. ClinicalDocument.id "1.2.345.6789.224" replaces ClinicalDocument.id "1.2.345.6789.456", which itself is an addendum to ClinicalDocument.id "1.2.345.6789.123") - expected behavior would be to render the replacement as the addendum (e.g. render ClinicalDocument.id "1.2.345.6789.224" as the addendum to ClinicalDocument.id "1.2.345.6789.123");

[2] addendum to a replaced document (e.g. ClinicalDocument.id "1.2.345.6789.456" appends ClinicalDocument.id "1.2.345.6789.123", which has been replaced by ClinicalDocument.id "1.2.345.6789.266") - expected behavior would be to render the addendum along with the replacement (e.g. render ClinicalDocument.id "1.2.345.6789.456" as an addendum to ClinicalDocument.id "1.2.345.6789.266").

Document transformations

A CDA document can be a transformation from some other format, meaning that it has undergone a machine translation from some other format (such as DICOM SR). In this case, relatedDocument.typeCode should be set to "XFRM".

A proper transformation must ensure that the human readable clinical content of the report is not impacted. Local business rules determine whether or not a transformed report replaces the source, but typically this would not be the case. If it is, an additional relationship of type "RPLC" is to be used. The "XFRM" relationship can also be used when translating a document in a local format into CDA for the purpose of exchange. In this case, the target of the "XFRM" relationship is the local document identifier.

5.2.3.2 ServiceEvent

ServiceEvent

The ServiceEvent is used to represent the main activity being documented. It may used to represent a specific procedure, such as a colonoscopy, an appendectomy, or other clinical activity. When the ClinicalDocument represents a summary of care, the ServiceEvent.code can be set to "PCPR" to indicate the service is care provisioning.

5.2.3.2.1 documentationOf

In some cases, the ServiceEvent is inherent in the ClinicalDocument.code, such as where ClinicalDocument.code is "History and Physical Report" and the procedure being documented is a "History and Physical". A ServiceEvent can further specialize the act inherent in the ClinicalDocument.code, such as where the ClinicalDocument.code is simply "Procedure Report" and the procedure was a "colonoscopy". If ServiceEvent is included, it must be equivalent to or further specialize the value inherent in the ClinicalDocument.code, and shall not conflict with the value inherent in the ClinicalDocument.code, as such a conflict would constitute an ambiguous situation.

EncompassingEncounter.effectiveTime

For Encounters, the effectiveTime is the "administrative" time, i.e., the encounter start and end date as established by business rules. For inpatient encounters, the effectiveTime/low value is the admission date and time and the effectiveTime/high value is the discharge date and time. Note: If the encounter is still active at the time of document creation, the effectiveTime/high element SHALL be omitted to indicate the encounter is on-going. This is preferred over using a nullFlavor.

HealthCareFacility.id

An optional HealthCareFacility.id can be sent to uniquely identify the health care facility.

HealthCareFacility.code

The setting of an encounter (e.g. cardiology clinic, primary care clinic, rehabilitation hospital, skilled nursing facility) can be expressed in HealthCareFacility.code. A value set ServiceDeliveryLocationRoleType is provided for the this field.

Note: In some cases, the setting of the encounter is inherent in the ClinicalDocument.code, such as where ClinicalDocument.code is "Diabetes Clinic Progress Note". The setting of an encounter can also be transmitted in the HealthCareFacility.code attribute. If HealthCareFacility.code is sent, it should be equivalent to or further specialize the value inherent in the ClinicalDocument.code (such as where the ClinicalDocument.code is simply "Clinic Progress Note" and the value of HealthCareFacility.code is "cardiology clinic"), and shall not conflict with the value inherent in the ClinicalDocument.code, as such a conflict would constitute an ambiguous situation.

5.2.3.5.5 Place

The entity playing the role of HealthCareFacility is a place (Place class).

The setting (place) and physical location are not the same. There is a many-to-many relationship between setting and the physical location where care is delivered. Thus, a particular room can provide the setting for cardiology clinic one day, and for primary care clinic another day; and cardiology clinic today might be held in one physical location, but in another physical location tomorrow.

5.2.3.5.6 Organization

The entity scoping the HealthCareFacility role is an organization (Organization class). When the location is an organization, this is indicated by the presence of a scoping Organization, without a playing Place.

5.2.3.5.7 responsibleParty

The responsibleParty participant represents the participant having primary legal responsibility for the encounter. This differs from the legalAuthenticator participant in that the legalAuthenticator may or may not be the responsible party, and is serving a medical records function by signing off on the document, moving it into a completed state.

responsibleParty.typeCode

The responsibleParty.typeCode is fixed to "RESP" to indicate the responsible party i.e. The person or organization that has primary responsibility for the encounter. The responsible party is not necessarily present in an action, but is accountable for the action through the power to delegate, and the duty to review actions with the performing actor after the fact. This responsibility may be ethical, legal, contractual, fiscal, or fiduciary in nature.

Table X: Fixed responsibleParty.typeCode

Code System: ParticipationType (HL7) Code System OID: 2.16.840.1.113883.5.90

A responsibleParty is a person or organization in the role of an assigned entity (AssignedEntity class). An assigned entity is a person assigned to the role by the scoping organization. The entity playing the role is a person (Person class). The entity scoping the role is an organization (Organization class).

5.3 Body

5.3.1 Body Choice

The CDA body choice can be either a document body in a format other than XML, or the CDA structured body. Every CDA document has exactly one body, associated with the ClinicalDocument class through the component relationship.

5.3.1.1 component

The component class relates the ClinicalDocument header to the body choice; NonXMLBody or StructuredBody.

Code System: ActMood (HL7) Code System OID: 2.16.840.1.113883.5.1001

NonXMLBody.text

NonXMLBody.text is used to reference data that is stored externally to the CDA document or to encode the data directly inline. Rendering a referenced non-XML body requires a software tool that recognizes the particular MIME media type for this type of body.

NonXMLBody.confidentialityCode

Confidentiality is a required contextual component of CDA, where the value expressed in the ClinicalDocument can be overridden for the NonXMLBody of the document.

NonXMLBody.languageCode

Specifies the human language of character data (whether they be in contents or attribute values). The values of the attribute are language identifiers as defined by the IETF (Internet Engineering Task Force) RFC 3066 for the Identification of Languages, ed. H. Alvestrand. 1995, which obsoletes RFC 1766. The HL7 code system for these values is "2.16.840.1.113883.6.121". Language is a contextual component of CDA, where the value expressed in the header holds true for the entire document, unless overridden by the NonXMLBody (as further described in CDA Context).

5.3.1.3 StructuredBody

The StructuredBody class represents a CDA document body that is comprised of one or more document sections.

The author participant (described above, see author), can be ascribed to a CDA section, where it overrides the value(s) propagated from the CDA header.

5.3.3.2 informant

The informant participant (described above, see informant), can be ascribed to a CDA section where it overrides the value(s) propagated from the CDA header.

5.3.3.3 subject

The subject participant represents the primary target of the entries recorded in the document. Most of the time the subject is the same as the recordTarget (see recordTarget), but need not be, for instance when the subject is a fetus observed in an obstetrical ultrasound.

The subject participant can be ascribed to a CDA section or a CDA entry. It propagates to nested components, unless overridden. The subject of a document is presumed to be the patient.

5.3.4 Section Relationships

5.3.4.1 component

The "component" Act Relationship is used to nest a Section within a Section. Context propagates to nested sections (see CDA Context). Refer to component above for more information.

5.3.4.2 entry

The relationship between a section and its entries is encoded in the intervening "entry" Act Relationship.

The narrative of each Section, together with the multimedia content referenced in the narrative, comprises the complete authenticated content of the Section. This multimedia content consists of ObservationMedia and RegionOfInterest entries referenced by tags in the Section.text. This is the only case where the entries contain authenticated content that must be rendered with the narrative.

NOTE: See Referencing in and out of the narrative block for a discussion of referencing in and out of a section's narrative block.

Table X: entry Attributes
Attribute Name	Data Type	Cardinality	Code Binding	Binding Type
typeCode	CS	[0..1]	V:x_ActRelationshipEntry	Fixed
contextConductionInd	BL	[0..1]

entry.typeCode

In terms of the relationship between a section and its entries, CDA defines a default general case, and a more specific case that can be used when applicable.

The entry relationship is defaulted to "COMP" (component), for the general case where the only assertion is that the related entries are contained within the source section and no other semantics are implied. In this case, the narrative is the original authenticated content. The CDA entries are created by various techniques (e.g., natural language processing, a human coder, a structured data entry tool that outputs both entries and a text report). The method of entry creation may be indicated by the entry participants (e.g., by identifying the algorithm or person that generated them). Relationships between various entries (such as two Observations or an Observation and an ObservationMedia) are encoded using the relationship types defined in entryRelationship.

A section may also have no narrative content in the case where the entries represent information that is not part of the clinical content of the document. A report may embed information referencing evidence data, reagents, calibration or other information that may be used for later processing but is not part of the clinical content. Such entries are also linked to the Section with ActRelationships possessing typeCode="COMP".

The entry relationship "DRIV" (is derived from) can be used in the special case where the narrative is fully derived from CDA Entries. When a report consisting entirely of structured entries is transformed into CDA, the encoding application must ensure that the authenticated content (narrative plus multimedia) is a faithful and complete rendering of the clinical content of the structured source data. This ensures that the narrative plus multimedia represents, as in all CDA documents, the complete authenticated content of the Section. In this case, narrative plus multimedia does not contain any clinical content that is not present in the Entries. An example of this case is a DICOM Structured Reporting document of obstetrical measurements made by ultrasound, rendered into a tabular report by a program converting it to CDA narrative block. If the typeCode of the ActRelationship linking these Entries to the Section was "DRIV", it would indicate to a receiving application: 1) the source of the narrative block is the Entries; 2) the contents of the two are equivalent.

The entries sourced from a Section may have a mix of ActRelationship typeCodes. In such a case, the union of the targets with a "DRIV" relationship are those used to generate the narrative block, and are those that, taken in total, are equivalent to the narrative block. Additional entries with "COMP" relationships are contained within the same section, with no implied semantics.

entry.contextConductionInd

The component.contextConductionInd indicator is fixed to "true". Ancestor elements () which propagate, will conduct through this component class to the associated child element.

5.3.5 Section Narrative Block

The Section.text field is used to store narrative to be rendered, as described above in CDA Conformance, and is therefore referred to as the CDA Narrative Block.

The CDA Narrative Block schema can be found here.

The content model of the CDA Narrative Block schema is specially hand crafted to meet the requirements outlined above (see Human Readability and Rendering CDA Documents). The schema is registered as a MIME type (text/x-hl7-text+xml), which is the fixed media type for Section.text. Components of the schema are described in the sections that follow.

5.3.5.1 <content>

The CDA <content> element is used to wrap a string of text so that it can be explicitly referenced, or so that it can suggest rendering characteristics. The <content> element can nest recursively, which enables wrapping a string of plain text down to as small a chunk as desired.

The <content> element contains an optional identifier, that can serve as the target of a reference. All values of attributes of type XML ID must be unique within the document (per the W3C XML specification). The originalText component of a RIM attribute present in any CDA entry can make explicit reference to the identifier, thereby indicating the original text associated with the attribute in the CDA entry.

Note: The <content> element is not the only element which can serve as the target of a reference. All narrative elements (including <text>) contain an ID element which can be referenced by the originalText component in a CDA entry. <content> is simply a tool which can be used to reference only a portion of a longer string contained in another narrative element.

Example X

<section>
   <code code="10153-2" 
    codeSystem="2.16.840.1.113883.6.1" 
    codeSystemName="LOINC"/>

          codeSystemName="SNOMED CT" 
          displayName="Asthma">
            <originalText>

         </code>
         <statusCode code="completed"/>
      </observation>
   </entry>
</section>

There is no requirement that CDA entries must reference into the CDA Narrative Block. The referencing mechanism can be used where it is important to represent the original text component of a coded CDA entry.

The <content> element contains an optional "revised" attribute that can be valued with "insert" or "delete", which can be used to indicate narrative changes from the last version of a CDA document. The attribute is limited to a single generation, in that it only reflects the changes from the preceding version of a document. If applied, it needs to be used in conjunction with standard CDA revision tracking. Changes to a CDA document that has been released for patient care still require a formal versioning and revision, and the revised document can optionally carry the "revised" attribute to show the delta in the narrative. Receivers are required to interpret the "revised" attribute when rendering by visually distinguishing or suppressing deleted narrative.

5.3.5.2 <linkHtml>

The CDA <linkHtml> is a generic referencing mechanism, similar, but not identical, to the HTML anchor tag. It can be used to reference identifiers that are either internal or external to the document.

Multimedia that is integral to a document, and part of the attestable content of the document requires the use of the ObservationMedia CDA entry, which is referenced by the <renderMultiMedia> element (see <renderMultiMedia>). Multimedia that is simply referenced by the document and not an integral part of the document can use <linkHtml>.

The source of a link uses the linkHtml.href attribute. The target of an internal reference is an identifier of type XML ID, which can exist on other elements in the same or a different narrative block, or XML ID attributes that have been added to the <section>, <ObservationMedia>, or <renderMultiMedia> elements of the CDA Schema. The linkHtml.name attribute is deprecated, because attributes of type XML ID provide an alternative and more consistent target for referencing. Following the conventions of HTML, an internal link is prefaced with the pound sign, as shown in the following example.

Example X

<section ID="SECT001">
   <code code="10164-2" codeSystem="2.16.840.1.113883.6.1" 
    codeSystemName="LOINC"/>

   <text>History of coronary artery disease, as noted
    <linkHtml href="#SECT001">above</linkHtml>.</text>
</section>

CDA links do not convey shareable meaning. Shareable semantics are only achieved by the inclusion of CDA entries and their associated formalized relationships. There is no requirement that a receiver render an internal or external link, or the target of an external link.

5.3.5.3 <sub> and <sup>

The CDA <sub> and <sup> elements are used to indicate subscripts and superscripts, respectively.

Receivers are required to interpret these elements when rendering by visually distinguishing subscripted and superscripted characters.

5.3.5.4 <br>

The CDA <br/> element is used to indicate a hard line break. It differs from the CDA <paragraph> element in that the <br/> element has no content. Receivers are required to interpret this element when rendering so as to represent a line break.

5.3.5.5 <footnote> and <footnoteRef>

The CDA <footnote> element is used to indicate a footnote. The element contains the footnote, inline with the flow of text to which it is applied.

The <footnoteRef> element can reference an existing footnote in the same or different CDA Narrative Block of the same document. It can be used when the same footnote is being used multiple times. The value of the footnoteRef.IDREF must be an footnote.ID value in the same document.

Receivers are required to interpret these elements when rendering by visually distinguishing footnoted text. The exact rendition is at the discretion of the recipient, and might include a mark at the location of the footnote with a hyperlink to the footnoted text, a simple demarcation (such as "This is the text [this is the footnote] that is being footnoted"), etc.

5.3.5.6 <renderMultiMedia>

The CDA <renderMultiMedia> element references external multimedia that is integral to a document, and part of the attestable content of the document, and serves to show where the referenced multimedia is to be rendered.

The <renderMultiMedia> element has an optional <caption>, and contains a required referencedObject attribute (of type XML IDREFS), the values of which must equal the XML ID value(s) of ObservationMedia or RegionOfInterest CDA entries within the same document.

Example X

<section>
   <code code="8709-8" codeSystem="2.16.840.1.113883.6.1"

            <reference value="left_hand_image.jpeg"/>
         </value>
      </observationMedia>
   </entry>
</section>

Multimedia that is simply referenced by the document and not an integral part of the document must use <linkHtml>.

The expected behavior is that the referenced multimedia should be rendered or referenced at the point of reference. Where a caption is present, it must also be rendered. <renderMultiMedia> can either reference a single ObservationMedia, or one or more RegionOfInterest. If <renderMultiMedia> references a single ObservationMedia, that ObservationMedia should be rendered or referenced at the point of reference. If <renderMultiMedia> references one or more RegionOfInterest, all RegionOfInterests should be rendered or referenced at the point of reference, atop the multimedia they are regions of. If <renderMultiMedia> references more than one RegionOfInterest, each RegionOfInterest must be a region on the same multimedia.

5.3.5.7 <paragraph>

A CDA <paragraph> is similar to the HTML paragraph, which allows blocks of narrative to be broken up into logically consistent structures. A CDA <paragraph> element contains an optional caption, which if present must come first before any other character data.

5.3.5.8 <list>

A CDA <list> is similar to the HTML list. A CDA <list> has an optional caption, and contains one or more <item> elements. A CDA <item> element contains an optional caption, which if present must come first before any other character data. The required listType attribute specifies whether the <list> is ordered or unordered (with unordered being the default). Unordered lists are typically rendered with bullets, whereas ordered lists are typically rendered with numbers, although this is not a requirement.

5.3.5.9 <table>

The CDA <table> is similar to the HTML table. The table markup is for presentation purposes only and, unlike a database table, does not possess meaningful field names. Remember to access the discrete data conveyed in a CDA document, process the RIM models contained within the <entry> element.

CDA modifies the strict XHTML table model by removing formatting tags and by setting the content model of cells to be similar to the contents of other elements in the CDA Narrative Block. A notable enhancement to the CDA R2.1 standard is the support of the <table> element within <td> & <th> elements. The support of tables within tables was not supported in CDA R2.0, but has been added for those implementation requiring complex table layouts. For definitions of the @align and @valign attributes see the W3C HTML 4.01 Specification section 11.3.2 <http://www.w3.org/TR/html401/struct/tables.html#h-11.3.2>.

The table.border, table.cellspacing, and table.cellpadding attributes are deprecated, because the styleCode attribute (see styleCode attribute) provides a more consistent way for senders to suggest rendering characteristics.

5.3.5.10 <caption>

The CDA <caption> is a label for a paragraph, list, list item, table, or table cell. It can also be used within the <renderMultiMedia> element to indicate a label for referenced ObservationMedia and RegionOfInterest entries. A <caption> contains plain text and may contain links and footnotes.

5.3.5.11 styleCode attribute

The styleCode attribute is used within the CDA Narrative Block to give the instance author the ability to suggest rendering characteristics of the nested character data. Receivers are not required to render documents using the style hints provided and can present stylized text in accordance with their local style conventions.

The value set is drawn from the HL7 styleType vocabulary domain, and has a CWE coding strength.

Table X: Value set for styleCode (CWE)
Code	Definition
Font style (Defines font rendering characteristics.)
Bold	Render with a bold font.
Underline	Render with an underlines font.
Italics	Render italicized.
Emphasis	Render with some type of emphasis.
Table rule style (Defines table cell rendering characteristics.
Lrule	Render cell with left-sided rule.
Rrule	Render cell with right-sided rule.
Toprule	Render cell with rule on top.
Botrule	Render cell with rule on bottom.
Ordered list style (Defines rendering characteristics for ordered lists.)
Arabic	List is ordered using Arabic numerals: 1, 2, 3.
LittleRoman	List is ordered using little Roman numerals: i, ii, iii.
BigRoman	List is ordered using big Roman numerals: I, II, III.
LittleAlpha	List is ordered using little alpha characters: a, b, c.
BigAlpha	List is ordered using big alpha characters: A, B, C.
Unordered list style (Defines rendering characteristics for unordered lists.)
Disc	List bullets are simple solid discs.
Circle	List bullets are hollow discs.
Square	List bullets are solid squares.

Local extensions to the styleType vocabulary domain must follow the following convention: [x][A-Za-z][A-Za-z0-9]* (first character is "x", second character is an upper or lower case A-Z, remaining characters are any combination of upper and lower case letters or numbers).

The styleCode attribute can contain multiple values, separated by white space. Where an element containing a styleCode attribute is nested within another element containing a styleCode attribute, the style effects are additive, as in the following example:

Example X

<section>
   <text><content styleCode="Bold">This is rendered bold, 
    <content styleCode="Italics">this is rendered bold and 
    italicized,</content> this is rendered bold. </content>
    <content styleCode="Bold Italics">This is also rendered 
    bold and italicized.</content>
   </text>
</section>

5.3.5.12 Referencing in and out of the narrative block

NOTE: See entry for a discussion of the relationships between a section and its contained entries.

To summarize the mechanisms for referencing in and out of the CDA Narrative Block:

CDA entries can point in to the <content> element of the CDA Narrative Block (see <content>).

The <linkHtml> element of the CDA Narrative Block can reference targets that are either internal or external to the document (see <linkHtml>).

The <footnoteRef> element of the CDA Narrative Block can reference a <footnote> element in the same or different CDA Narrative Block of the same document (see <footnote> and <footnoteRef>).

The <renderMultiMedia> element of the CDA Narrative Block can point out to CDA ObservationMedia and RegionOfInterest entries of the same document (see <renderMultiMedia>).

5.3.6 Entry Acts

CDA entries represent the structured computer-processable components within a document section. Each section can contain zero to many entries.

Clinical documents contain a wide breadth of content, requiring much of the RIM to enable a full and complete encoding. The current set of CDA entries have been developed in response to identified requirements and scenarios that are in CDA's scope. Rather than creating specific entries for each scenario, similar requirements are merged to create broader entries, which can then be constrained within a particular realm or implementation. This approach is consistent with the approach taken by CEN, DICOM, and OpenEHR.

The model for CDA entries is derived from the shared HL7 Clinical Statement model, which is a collaborative project between several committees striving to provide a consistent representation of clinical observations and acts across various V3 specifications.

5.3.6.1 Act

A derivative of the RIM Act class, to be used when the other classes present in the CDA Clinical Statement choice pattern are not appropriate.

Code System: ActClass (HL7) Code System OID: 2.16.840.1.113883.5.6

Act.moodCode

The intended use of the Act statement: as a report of fact, a command, a possibility, a goal, etc. Since the mood code is a determining factor for the meaning of an entire Act object, the mood must always be known. This means that whenever an act object is instantiated, the mood attribute SHALL be assigned to a valid code, and the mood assignment SHALL NOT change throughout the lifetime of the act object.

Code System: ActMood (HL7) Code System OID: 2.16.840.1.113883.5.1001

Act.id

A unique identifier for the Act.

Act.code

The particular kind of Act that the Act-instance represents within its class. Act.code, if used, SHALL be a specialization of the Act.classCode. This attribute defines a specific sub-type of a given Act type (determined by the "classCode" attribute). It allows the use of rich terminologies such as LOINC and SNOMED to represent sub-types of the limited set of Act types defined by "classCode." The Act.code is bound to the ActCode concept domain.

Act.actionNegationInd

The Act.actionNegationInd works as a negative existence quantifier on the actual, intended or described Act event. In Event mood, it indicates the defined act did not occur. In Intent mood, it indicates the defined act is not intended/desired to occur. In Criterion mood, it indicates that the condition is based on the non-occurrence of the event. It is nonsensical to have a negationInd of true for acts with a mood of definition.

The actionNegationInd negates the Act as described by the descriptive properties which are: classCode, code, statusCode, effectiveTime, activityTime, priorityCode, reasonCode and any of their components.

The remaining properties represent the document characteristics, E.g. Act.id, Act.moodCode, Act.confidentialityCode, and particularly the Author-Participation are not negated. These document characteristic properties always have the same meaning: i.e., the author remains to be the author of the negative observation. Also, most ActRelationships (except for components) are not included in the negation. Refer to the attribute isDocumentCharacteristic property and the ActRelationshipType and ParticipationType code system isDocumentCharacteristic properties for specific guidance.

Act.negationInd

Act.negationInd, is deprecated in RIM 2.35, and CDA R2.1 retains it for backwards compatibility. CDA R2.1 compliant implementation guides should use actionNegationInd moving forward.

Act.text

A renderable textual or multimedia description (or reference to a description) of the complete information which would reasonably be expected to be displayed to a human reader conveyed by the Act. The Act.text attribute can reference the associated narrative content in the section using the XML ID attribute added to the Narrative Text elements.

Act.statusCode

The status reflects the state of the activity. The RIM based state machine diagram depicts the allowable state transitions that an Act.StatusCodes can take on.

Table X: Value set for Act.statusCode
V:ActStatus [2.16.840.1.113883.1.11.15933] (CLOSED)

new	new	suspended	suspended
nullified	nullified	obsolete	obsolete
Code System: ActStatus (HL7) Code System OID: 2.16.840.1.113883.5.14

Act.effectiveTime

Act.effectiveTime is used to indicate the clinically or operationally relevant time of an act, exclusive of administrative activity.

Act.activityTime

Act.activityTime is a time expression specifying when an act occurs, inclusive of administrative time E.g. times of component actions, such as preparation and clean-up. Depending on the mood code used, it represents the time the act occurred, is supposed to occur, is scheduled to occur, etc.

Act.availabilityTime

Act.availabilityTime is the point in time at which information about an act instance (regardless of mood) first became available to a system. The availabilityTime is metadata describing the recording of, not the act itself.

Act.priorityCode

The urgency under which the Act happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. The Act.priorityCode is bound to the ActPriority concept domain.

Act.confidentialityCode

Constraints around appropriate disclosure of information about this Act, regardless of mood. The Act.confidentialityCode is bound to the Confidentiality concept domain.

Act.uncertaintyCode

An indication that the Act statement as a whole, with its subordinate components has been asserted to be uncertain in some way. The use of the uncertaintyCode is appropriate only if the entirety of the Act and its dependent Acts is questioned. The Act.uncertaintyCode is bound to the ActUncertainty concept domain.

Act.reasonCode

The motivation, cause, or rationale of an Act, when such rationale is not reasonably represented as an ActRelationship of type "has reason" linking to another Act. The Act.reasonCode is bound to the ActReason concept domain.

Most reasons for acts can be clearly expressed by linking the new Act to another prior Act record using an ActRelationship of type "has reason." This simply states that the prior Act is a reason for the new Act (see ActRelationship). The prior act can then be a specific existing act or a textual explanation. This works for most cases, and the more specific the reason data is, the more should this reason ActRelationship be used instead of the reasonCode.

The reasonCode remains as a place for common reasons that are not related to a prior Act or any other condition expressed in Acts. Indicators that something was required by law or was on the request of a patient may qualify. However, if that piece of legislation, regulation, or the contract or the patient request can be represented as an Act (and they usually can), such a representation is preferable to the reasonCode.

Act.languageCode

The primary language in which this Act statement is specified, particularly the language of the Act.text. The Act.languageCode is bound to the HumanLanguage concept domain.

5.3.6.2 Encounter

Encounter

A derivative of the RIM PatientEncounter class, used to represent related encounters, such as follow-up visits or referenced past encounters.

NOTE: The EncompassingEncounter class in the CDA Header (see Header Relationships) represents the setting of the clinical encounter during which the documented act occurred. The Encounter class in the CDA Body is used to represent other related encounters.

Encounter.classCode

The Encounter.classCode is fixed to "ENC" to represent an encounter. The encounter class is used to represent an interaction between a patient and healthcare participant(s) for the purpose of providing patient service(s) or assessing the health status of a patient.

Encounter.actionNegationInd

The Encounter.actionNegationInd works as a negative existence quantifier on the actual, intended or described Encounter event. In Event mood, it indicates the defined encounter did not occur. In Intent mood, it indicates the defined encounter is not intended/desired to occur. In Criterion mood, it indicates that the condition is based on the non-occurrence of the event. It is nonsensical to have a negationInd of true for acts with a mood of definition.

The actionNegationInd negates the Encounter as described by the descriptive properties which are: classCode, code, statusCode, effectiveTime, activityTime, priorityCode, reasonCode, admissionReferralSourceCode, lengthOfStayQuantity, dischargeDispositionCode, preAdmitTestInd, specialCourtesiesCode, specialArrangementCode and any of their components.

The remaining properties represent the document characteristics, E.g. Encounter.id, Encounter.moodCode, Encounter.confidentialityCode, and particularly the Author-Participation are not negated. These document characteristic properties always have the same meaning: i.e., the author remains to be the author of the negative encounter. Also, most ActRelationships (except for components) are not included in the negation. Refer to the attribute isDocumentCharacteristic property and the ActRelationshipType and ParticipationType code system isDocumentCharacteristic properties for specific guidance.

Encounter.text

A renderable textual or multimedia description (or reference to a description) of the complete information which would reasonably be expected to be displayed to a human reader conveyed by the Encounter. The Encounter.text attribute can reference the associated narrative content in the section using the XML ID attribute added to the Narrative Text elements.

Encounter.statusCode

The status reflects the state of the Encounter. The RIM based state machine diagram depicts the allowable state transitions that an Encounter.statusCode can take on.

Encounter.effectiveTime

For Encounters, the effectiveTime is the "administrative" time, i.e., the encounter start and end date as established by business rules. For inpatient encounters, the effectiveTime/low value is the admission date and time and the effectiveTime/high value is the discharge date and time. Note: If the encounter is still active at the time of document creation, the effectiveTime/high element can be omitted to indicate the encounter is on-going.

Encounter.activityTime

Encounter.activityTime is a time expression specifying when an Encounter occurs, inclusive of administrative time E.g. times of component actions, such as preparation and clean-up. Depending on the mood code used, it represents the time the Encounter occurred, is supposed to occur, is scheduled to occur, etc.

Encounter.availabilityTime

Encounter.availabilityTime is the point in time at which information about an Encounter instance (regardless of mood) first became available to a system. The availabilityTime is metadata describing the recording of, not the Encounter itself.

Encounter.priorityCode

The urgency under which the Encounter happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. The Encounter.priorityCode is bound to the ActPriority concept domain.

Encounter.confidentialityCode

Constraints around appropriate disclosure of information about this Encounter, regardless of mood. The Encounter.confidentialityCode is bound to the Confidentiality concept domain.

Encounter.reasonCode

The motivation, cause, or rationale of an Encounter, when such rationale is not reasonably represented as an ActRelationship of type "has reason" linking to another Act. The Encounter.reasonCode is bound to the ActReason concept domain.

Encounter.languageCode

The primary language in which this Encounter statement is specified, particularly the language of the Encounter.text. The Encounter.languageCode is bound to the HumanLanguage concept domain.

Encounter.admissionReferralSourceCode

The optional EncompassingEncounter.admissionReferralSourceCode can be use to depict the type of place or organization responsible for the patient's care immediately prior to a patient encounter.

Encounter.lengthOfStayQuantity

The total quantity of time when the subject is expected to be or was resident at a facility as part of an encounter. Note, the actual days quantity cannot be simply calculated from the admission and discharge dates because of possible leaves of absence.

Encounter.dischargeDispositionCode

The optional EncompassingEncounter.dischargeDispositionCode can be used to depict the disposition of the patient at the time of hospital discharge (e.g., discharged to home, expired, against medical advice, etc.).

Encounter.preAdmitTestInd

An indication that pre-admission tests are required for this patient encounter.

Encounter.specialCourtesiesCode

Extraordinary considerations or services provided within the context of the Patient Encounter. Examples include: Professional courtesy, VIP courtesies, no courtesies

Encounter.specialArrangementCode

Extraordinary provisions required in the context of the patient encounter. For encounters in intention moods, this information can be used to identify special arrangements that will need to be made for the incoming patient.

5.3.6.3 Observation

Observation

A derivative of the Observation(§ RIM 2.35) class, it is intended to result in new information about a subject. The main difference between Observations and other Acts is that Observations have a value attribute. The code attribute of Observation and the value attribute of Observation must be considered in combination to determine the semantics of the observation.

Code System: ActMood (HL7) Code System OID: 2.16.840.1.113883.5.1001

Observation.id

A unique identifier for the Observation.

Observation.code

The particular kind of Observation that the Observation-instance represents within its class. Observation.code, if used, SHALL be a specialization of the Observation.classCode. This attribute defines a specific sub-type of a given Observation type (determined by the "classCode" attribute). The Observation.code is bound to the ActCode concept domain.

Observation.actionNegationInd

The Observation.actionNegationInd works as a negative existence quantifier on the actual, intended or described observation event. In Event mood, it indicates the defined observation did not occur. In Intent mood, it indicates the defined observation is not intended/desired to occur. In Criterion mood, it indicates that the condition is based on the non-occurrence of the event. It is nonsensical to have a negationInd of true for acts with a mood of definition.

The actionNegationInd negates the Observation as described by the descriptive properties which are: classCode, code, statusCode, effectiveTime, activityTime, priorityCode, derivationExpr, repeatNumber, isCriterionInd, value, valueNegationInd, interpretationCode, methodCode, targetSiteCode, and any of their components.

The remaining properties represent the document characteristics, E.g. Observatoin.id, Observation.moodCode, Observation.confidentialityCode, and particularly the Author-Participation are not negated. These document characteristic properties always have the same meaning: i.e., the author remains to be the author of the negative observation. Also, most ActRelationships (except for components) are not included in the negation. Refer to the attribute isDocumentCharacteristic property and the ActRelationshipType and ParticipationType code system isDocumentCharacteristic properties for specific guidance.

Observation.negationInd

Observation.negationInd, is deprecated in RIM 2.35, and CDA R2.1 retains it for backwards compatibility. It was deprecated as the type of negation required knowledge of template documentation to determine the actual type of negation I.e. value or action negation. CDA R2.1 compliant implementation guides should use actionNegationInd or valueNegationInd moving forward.

Observation.derivationExpr

A character string containing a formal language expression that specifies how the Observation's attributes are, should be, or have been derived from input parameters associated with derivation relationships. Derived observations can be defined through association with other observations using ActRelationships of type "derivation." For example, to define a derived observation for Mean Corpuscular Hemoglobin (MCH) one will associate the MCH observation with a Hemoglobin (HGB) observation and a Red Blood cell Count (RBC) observation: the derivation expression value encodes the formula: MCH = HGB / RBC.

Observation.title

A word or phrase by which a specific Observation may be known among people. This is not a formal identifier but rather a human-recognizable common name. However it is similar to the id attribute in that it refers to a specific Observation rather than a 'kind' of Observation. (For definition mood, the title refers to that specific definition, rather than to a broad category that might be conveyed with Observation.code.)

Observation.text

A renderable textual or multimedia description (or reference to a description) of the complete information which would reasonably be expected to be displayed to a human reader conveyed by the Observation. The Observation.text attribute can reference the associated narrative content in the section using the XML ID attribute added to the Narrative Text elements.

Observation.statusCode

The status reflects the state of the activity. In the case of an Observation, this is the status of the activity of observing (e.g., "new," "complete," "cancelled"), not the status of what is being observed (e.g., disease status, "Active" allergy to penicillin). To convey the status of the subject being observed, consider coordinating it into the code or value attribute of the Observation or using a related Observation. The RIM based state machine diagram depicts the allowable state transitions that an Observation.StatusCode can take on.

Observation.effectiveTime

Observation.effectiveTime is used to indicate the clinically or operationally relevant time of an observation, exclusive of administrative activity. For example, in a Blood Gas Analysis (BGA), a result might not be available for several minutes after the specimen was taken. The effectiveTime is the time the specimen was taken, the availabilityTime would be the time the result was available for review. For clinical Observations, the effectiveTime represents the time at which the observation holds (is effective) for the patient. In V2 the effectiveTime was known as the biologically relevant time.

Observation.activityTime

Observation.activityTime is a time expression specifying when an Observation occurs, inclusive of administrative time E.g. times of component actions, such as preparation and clean-up. Depending on the mood code used, it represents the time the observation occurred, is supposed to occur, is scheduled to occur, etc. When an observation of a prior symptom is made, the activityTime describes the time the observation is made, as opposed to effectiveTime which is the time the symptom is reported to have occurred. Thus the activityTime may be entirely different from the effectiveTime for the same observation instance.

Observation.availabilityTime

Observation.availabilityTime is the point in time at which information about an observation instance (regardless of mood) first became available to a system. The availabilityTime is metadata describing the recording of, not the Observation itself. For CDA documents, the availabilityTime reported for its contents, would represent the time the observation first became available to a source system generating the CDA document.

Observation.priorityCode

The urgency under which the Act happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. The Act.priorityCode is bound to the ActPriority concept domain.

Observation.confidentialityCode

Constraints around appropriate disclosure of information about this Observation, regardless of mood. The Observation.confidentialityCode is bound to the Confidentiality concept domain.

Observation.repeatNumber

An interval of integer numbers stating the minimal and maximal number of repetitions of the Observation.

Observation.uncertaintyCode

An indication that the Observation statement as a whole, with its subordinate components has been asserted to be uncertain in some way. The use of the uncertaintyCode is appropriate only if the entirety of the Observation and its dependent Acts is questioned. The Observation.uncertaintyCode is bound to the ActUncertainty concept domain. Note: Implementation Guides will need to provide explicit guidance on the proper evaluation and interpretation, as well as provide a default value assignment.

Observation.languageCode

The primary language in which this Observation statement is specified, particularly the language of the Observation.text. The Observation.languageCode is bound to the HumanLanguage concept domain.

Observation.isCriterionInd

Is defaulted to false, when set to true it indicates that the data conveyed by the act, including outbound associations, represent "criteria" for some other act, not a "real" act. I.e. If an Act exists with a classCode of ACT and a moodCode of RQO and isCriterionInd is true, it does not represent an order for an act. Rather, it represents a criteria that will match on all orders.

Observation.value

The result of the observation action. Extensive usage notes are available in the RIM, reference Value UsageNotes

Observation.valueNegationInd

Observation.valueNegationInd, indicates that when the observation event occurred, the finding communicated by the value attribute was NOT found. So, when we want to indicate the patient does not have asthma, we can negate a finding of asthma, using this indicator. Note: The RIM indicates that this attribute should only be used when the terminology used for Observation.value is not itself capable of expressing negated findings. (E.g. ICD9). Implementation experience may override the RIM definition and it's important to review template definitions and Value Set content and binding for consistent negation implementation. Existing CDA R2.0 implementations use negationInd in many C-CDA templates.

Observation.interpretationCode

A qualitative interpretation of the observation. These interpretation codes are sometimes called "abnormal flags," however, the judgment of normalcy is just one of the interpretations, and is often not relevant. For example, the susceptibility interpretations are not about "normalcy," and for any observation of a pathologic condition, it does not make sense to state the normalcy, since pathologic conditions are never considered "normal."

Observation.methodCode

The means or technique used to ascertain the observation. In all observations the method is already partially specified by the Observation.code. In this case, the methodCode NEED NOT be used at all. The methodCode MAY still be used to identify this method more clearly in addition to what is implied from the Observation.code. However, an information consumer system or process SHOULD NOT depend on this methodCode information for method detail that is implied by the Observation.code.

Observation.targetSiteCode

The anatomical site or system that is the focus of the observation. Most observation target sites are implied by the observation definition and Observation.code, or Observation.value. For example, "heart murmur" always has the heart as target. This attribute is used only when the observation target site needs to be refined, to distinguish right from left, etc. If the subject of the Observation is something other than a human patient or animal, the attribute is used analogously to specify a structural landmark of the thing where the Observation focuses. For example, if the subject is a lake, the site could be inflow and outflow, etc. If the subject is a lymphatic node, "hilus," "periphery," or other node sites would be valid target sites.

The following is an example of how an author can record a patient that has no known allergies. It uses the new valueNegationInd with an "Allergy to substance" code in the value element.

ObservationRange.code

The particular kind of Observation that the ObservationRange-instance represents within its class. ObservationRange.code, if used, SHALL be a specialization of the ObservationRange.classCode. This attribute defines a specific sub-type of a given Observation type (determined by the "classCode" attribute). The ObservationRange.code is bound to the ActCode concept domain.

ObservationRange.text

A renderable textual or multimedia description (or reference to a description) of the complete information which would reasonably be expected to be displayed to a human reader conveyed by the ObservationRange. The ObservationRange.text attribute can reference the associated narrative content in the section using the XML ID attribute added to the Narrative Text elements.

ObservationRange.isCriterionInd

Is set to true to indicate that the data conveyed by the ObservationRange, including outbound associations, represent "criteria" for some other act, not a "real" act. I.e. If an Act exists with a classCode of ACT and a moodCode of RQO and isCriterionInd is true, it does not represent an order for an act. Rather, it represents a criteria that will match on all orders.

ObservationRange.value

The result of the ObservationRange action. Extensive usage notes are available in the RIM, reference Value UsageNotes

ObservationRange.valueNegationInd

ObservationRange.valueNegationInd, indicates that when the ObservationRange event occurred, the finding communicated by the value attribute was NOT found. Note: This attribute should only be used when the terminology used for ObservationRange.value is not itself capable of expressing negated findings. (E.g. ICD9).

ObservationRange.interprerationCode

A qualitative interpretation of the ObservationRange. These interpretation codes are sometimes called "abnormal flags," however, the judgment of normalcy is just one of the interpretations, and is often not relevant. For example, the susceptibility interpretations are not about "normalcy," and for any observation of a pathologic condition, it does not make sense to state the normalcy, since pathologic conditions are never considered "normal."

5.3.6.4 ObservationMedia

Observation Media

A derivative of the RIM Observation class that represents multimedia that is logically part of the current document. This class is only for multimedia that is logically part of the attested content of the document. Rendering a referenced ObservationMedia requires a software tool that recognizes the particular MIME media type. The distinction between ObservationMedia and ExternalObservation is that ObservationMedia entries are part of the attested content of the document whereas ExternalObservations are not. For instance, when a clinician draws a picture as part of a progress note, that picture is represented as a CDA ObservationMedia. If that clinician is also describing a finding seen on a chest-x-ray, the referenced chest-x-ray is represented as a CDA ExternalObservation.

Table X: ObservationMedia Attributes

languageCode	CS	[0..1]	D:HumanLanguage	Closed
value	ED	[1..1]

NOTE: XML ID Attribute added

An XML attribute "ID" of type XML ID, is added to ObservationMedia within the CDA Schema. This attribute serves as the target of a <renderMultiMedia> reference (see <renderMultiMedia>). All values of attributes of type XML ID must be unique within the document (per the W3C XML specification).

ObservationMedia.classCode

The ObservationMedia.classCode is defaulted to "OBS" for Observation, but can be set to any sub-type of Observation that may more accurately characterize the multi-media referenced via the ObservationMedia class.

Specifies the human language of character data (whether they be in contents or attribute values).

ObservationMedia.value

The ObservationMedia.value is set to the xsi:type="ED" which enables the referencing of the multi-media object. Review the ED data type for more information about linking to files.

5.3.6.5 Organizer

Organizer

A derivative of the RIM Act class, which can be used to create arbitrary groupings of other CDA entries that share a common context. An Organizer can contain other Organizers and/or other CDA entries, by traversing the component relationship. An Organizer can refer to external acts by traversing the reference relationship. An Organizer cannot be the source of an entryRelationship relationship.

NOTE: CDA entries such as Observation can also contain other CDA entries by traversing the entryRelationship class. There is no requirement that the Organizer entry be used in order to group CDA entries.

Organizer.classCode

The Organizer.classCode can take on one of two values, BATTERY or CLUSTER.

CLUSTER is an ACT that organizes a set of component acts into a semantic grouping that have a shared subject. The subject may be either a subject participation (SBJ), subject act relationship (SUBJ), or child participation/act relationship types.
The BATTERY is an observation that is composed of a set of observations. These observations typically have a logical or practical grouping for generally accepted clinical or functional purposes, such as observations that are run together because of automation. A battery can define required and optional component observations and, in some cases, will define complex rules that determine whether or not a particular observation is made. BATTERY is a constraint on the Observation class in that it is understood to always be composed of component observations.

Organizer.effectiveTime

The optional Organizer.effectiveTime is used to indicate the clinically or operationally relevant time of an Organizer's component items, exclusive of administrative activity. For example, in a Blood Gas Analysis (BGA), a result might not be available for several minutes after the specimen was taken. The effectiveTime is the time the specimen was taken, the availabilityTime would be the time the result was available for review.

Organizer.activityTime

The optional Organizer.activityTime is a time expression specifying when the activityTime of the Organizer's component items occurred, inclusive of administrative time E.g. times of component actions, such as preparation and clean-up. Depending on the mood code used, it represents the time the component Acts occurred, is supposed to occur, is scheduled to occur, etc.

Organizer.availabilityTime

The optional Observation.availabilityTime is the point in time at which information about the component Acts regardless of mood) first became available to a system. The availabilityTime is metadata describing the recording of, not the Organizer's component activities themselves.

The optional priorityCode identifies the urgency under which the component Act's happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. The Organizer.priorityCode is bound to the ActPriority concept domain.

Organizer.confidentialityCode

The optional confidentialityCode identifies any constraints around appropriate disclosure of information about this Organizer and it's component Acts, regardless of mood. The Organizer.confidentialityCode is bound to the Confidentiality concept domain.

5.3.6.6 Procedure

Procedure.moodCode

The intended use of the Procedure statement: as a procedure report, a command, a possibility, a goal, etc. Since the mood code is a determining factor for the meaning of an entire Procedure object, the mood must always be known. This means that whenever an Procedure is instantiated, the mood attribute SHALL be assigned to a valid code, and the mood assignment SHALL NOT change throughout the lifetime of the Procedure.

Procedure.id

A unique identifier for the Procedure.

Procedure.code

The particular kind of Procedure that the Procedure-instance represents within its class. Procedure.code, if used, SHALL be a specialization of the Procedure.classCode. This attribute defines a specific sub-type of a given Procedure type (determined by the "classCode" attribute). The Procedure.code is bound to the ActProcedureCode concept domain.

Procedure.actionNegationInd

The Procedure.actionNegationInd works as a negative existence quantifier on the actual, intended or described Procedure event. In Event mood, it indicates the defined procedure did not occur. In Intent mood, it indicates the defined procedure is not intended/desired to occur. In Criterion mood, it indicates that the condition is based on the non-occurrence of the event. It is nonsensical to have a negationInd of true for acts with a mood of definition.

The actionNegationInd negates the Act as described by the descriptive properties which are: classCode, code, statusCode, effectiveTime, activityTime, priorityCode, isCriterionInd, methodCode, approachSiteCode, targetSiteCode and any of their components.

The remaining properties represent the document characteristics, E.g. Procedure.id, Procedure.moodCode, Procedure.confidentialityCode, and particularly the Author-Participation are not negated. These document characteristic properties always have the same meaning: i.e., the author remains to be the author of the negative observation. Also, most ActRelationships (except for components) are not included in the negation. Refer to the attribute isDocumentCharacteristic property and the ActRelationshipType and ParticipationType code system isDocumentCharacteristic properties for specific guidance.

Procedure.negationInd

Procedure.negationInd, is deprecated in RIM 2.35, and CDA R2.1 retains it for backwards compatibility. CDA R2.1 compliant implementation guides should use actionNegationInd moving forward.

Procedure.text

A renderable textual or multimedia description (or reference to a description) of the complete information which would reasonably be expected to be displayed to a human reader conveyed by the Procedure. The Procedure.text attribute can reference the associated narrative content in the section using the XML ID attribute added to the Narrative Text elements.

Procedure.statusCode

The status reflects the state of the activity. The RIM based state machine diagram depicts the allowable state transitions that an Procedure.statusCode can take on.

Code System: ActStatus (HL7) Code System OID: 2.16.840.1.113883.5.14

Procedure.effectiveTime

Procedure.effectiveTime is used to indicate the clinically or operationally relevant time of a procedure, exclusive of administrative activity. For a surgical procedure (operation), the effectiveTime is the time relevant for the patient, i.e., between incision and last suture. For transportation acts, the effective time is the time the transported payload is en route.

Procedure.activityTime

Procedure.activityTime is a time expression specifying when a procedure occurs, inclusive of administrative time E.g. times of component actions, such as preparation and clean-up. Depending on the mood code used, it represents the time the procedure occurred, is supposed to occur, is scheduled to occur, etc. For Procedures the activityTime can provide a needed administrative function by providing a more inclusive time to be anticipated in scheduling.

Procedure.availabilityTime

Procedure.availabilityTime is the point in time at which information about a procedure instance (regardless of mood) first became available to a system. The availabilityTime is metadata describing the recording of, not the procedure itself.

Procedure.priorityCode

The urgency under which the Act happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. The Procedure.priorityCode is bound to the ActPriority concept domain.

Procedure.confidentialityCode

Constraints around appropriate disclosure of information about this Procedure, regardless of mood. The Procedure.confidentialityCode is bound to the Confidentiality concept domain.

Procedure.uncertaintyCode

An indication that the Procedure statement as a whole, with its subordinate components has been asserted to be uncertain in some way. The use of the uncertaintyCode is appropriate only if the entirety of the Procedure and its dependent Acts is questioned. The Procedure.uncertaintyCode is bound to the ActUncertainty concept domain.

Procedure.languageCode

The primary language in which this Procedure statement is specified, particularly the language of the Procedure.text. The Procedure.languageCode is bound to the HumanLanguage concept domain.

Procedure.isCriterionInd

Is defaulted to false, when set to true it indicates that the data conveyed by the act, including outbound associations, represent "criteria" for some other act, not a "real" act. I.e. If an Act exists with a classCode of ACT and a moodCode of RQO and isCriterionInd is true, it does not represent an order for an act. Rather, it represents a criteria that will match on all orders.

Procedure.methodCode

The means or technique used to ascertain the observation. In some procedures the method is already partially specified by the Procedure.code. In this case, the methodCode NEED NOT be used at all. The methodCode MAY still be used to identify this method more clearly in addition to what is implied from the Procedure.code. However, an information consumer system or process SHOULD NOT depend on this methodCode information for method detail that is implied by the Procedure.code.

Procedure.approachSiteCode

The anatomical site or system through which the procedure reaches its target.

Procedure.targetSiteCode

The anatomical site or system that is the focus of the procedure. Most procedure target sites are implied by the procedure definition and Procedure.code, or Procedure.value. If the subject of the procedure is something other than a human patient or animal, the attribute is used analogously to specify a structural landmark of the thing where the Procedure occurred.

5.4 CDA Context

CDA context is set in the CDA header and applies to the entire document. Context can be overridden at the level of the body, section, and/or CDA entry.

5.4.1 Overview of CDA Context

A document, in a sense, is a contextual wrapper for its contents. Assertions in the document header are typically applicable to statements made in the body of the document, unless overridden. For instance, the patient identified in the header is assumed to be the subject of observations described in the body of the document, unless a different subject is explicitly stated, or the author identified in the header is assumed to be the author of the entire document, unless a different author is explicitly identified on a section. The objective of the CDA context rules are to make these practices explicit with relationship to the RIM, such that a computer will understand the context of a portion of a document the same way that a human interprets it.

At the same time, there is no guarantee that machine processing will identify a mistaken application of contextual rules. If a physician records an "outside diagnosis" in narrative but does not nullify the "informant" context, machine processing will not identify the switch in attribution. This is a special case illustrating the limits of automated validation of electronic records and would apply regardless of the context inheritance mechanism. In other words, from some errors of encoding, there is no recovery other than human review.

CDA's approach to context, and the propagation of that context to nested document components, follows these design principles:

CDA uses the RIM context mechanism (contextControlCode for Participations; contextConductionInd for ActRelationships), and assigns fixed values to these attributes to accomplish the design objectives below, thus constraining the RIM context model. CDA extends the context propagation property to designated attributes of the CDA Header, which also propagate through any ActRelationship for which contextConductionInd="true".
The CDA Header sets context for the entire document. A propagating value specified in the document header holds true throughout the document, unless explicitly overridden. This principal applies to both Participations and to designated attributes of the CDA Header. Contextual header components (i.e., those that have propagating values) include:
- Author
- Confidentiality
- Data enterer
- Human language
- Informant
- Legal authenticator
- Participant
- Record target
Context components that can be overridden at the level of the document body include:
- Confidentiality
- Human language
Context components that can be overridden at the level of a document section include:
- Author
- Confidentiality
- Human language
- Informant
- Subject
Context components that can be overridden at the level of a CDA entry include:
- Author
- Human language
- Informant
- Participant
- Subject
Context propagates from outer tags to nested tags. Context that is specified on an outer tag holds true for all nested tags, unless overridden on a nested tag. Context specified on a tag within the CDA body always overrides context propagated from an outer tag. For instance, the specification of authorship at a document section level overrides all authorship propagated from outer tags.
Context is sometimes known precisely, and is sometimes unknown, such as in the case where a document is comprised of a large unparsed narrative block that potentially includes statements that contradict outer context. Because CDA context always propagates unless overridden, the representation of unknown context is achieved by overriding with a null value.

5.4.2 Technical Aspects of CDA Context

The RIM defines the "context" of an act as those participants of the act that can be propagated to nested acts. In the RIM, whether or not contextual participants do propagate to nested acts depends on whether or not the intervening act relationship between parent and child act allows for conduction of context. The explicit representation of context, and whether or not the context on an act can propagate to nested acts, is expressed via the RIM attributes Participation.contextControlCode and ActRelationship.contextConductionInd. CDA constrains the general RIM context mechanism such that context always overrides and propagates, as shown in the following table.

Table X: CDA constraints on RIM context attributes
RIM attribute	Cardinality	Conformance	Fixed Value
Participation.contextControlCode	1..1	Mandatory (NULL values not permitted)	"OP" (overriding, propagating)
ActRelationship.contextConductionInd	1..1	Mandatory (NULL values not permitted)	"true"*

*The one exception to this is entryRelationship.contextConductionInd, which is defaulted to "true", but can be changed to "false". See entryRelationship for details.

Where the context of a nested component is unknown, the propagated context must be overridden with a null-valued component, as shown in the following table.

Table X: Blocking context propagation with null values
Context	Null value representation
Author	AssignedAuthor.id = NULL; No playing entity; No scoping entity.
Confidentiality	confidentialityCode = NULL.
Human language	languageCode = NULL.
Informant	AssignedEntity.id = NULL; No playing entity; No scoping entity.
Participant	ParticipantRole.id = NULL; No playing entity; No scoping entity.

The following exhibit illustrates the CDA context model. ClinicalDocument has an author participant, a confidentialityCode, and a languageCode, all of which will propagate to nested acts. The component act relationship going from ClinicalDocument to bodyChoice has contextConductionInd fixed as "true", thus allowing for the propagation of context. The bodyChoice classes, NonXMLBody and StructuredBody, contain a confidentialityCode and languageCode which can be used to override the value specified in the header. The component act relationship going from StructuredBody to Section has contextConductionInd fixed at "true", thus the context on StructuredBody will propagate through to Section. Section can override confidentialityCode, languageCode, and author. A null value for the Section's author participant indicates that the author for that particular section is unknown.

Because context is always overriding and propagating, one can compute the context of a given node by looking for the most proximate assertion. The following example is a sample XPath expression that can be used to identify the <author> context of a section or entry:

Example X

(ancestor-or-self::*/author)[position()=last()]

5.4.3 InfrastructureRoot & CDA Classes

All of CDA classes inherits 1 attribute and 3 element from InfrastructureRoot. Infrastructure Root provides a set of infrastructure attributes that may be used in instances of HL7-specified, RIM-based classes. When valued in an instance, these attributes indicate whether the information structure is being constrained by specifically defined templates, realms or common element types.

An optional nullFlavor attribute has been added to each CDA class. When the class is null, this code can be used to indicate the flavor of null that is intended.

The following 3 optional elements have been added at the beginning of each CDA class:

realmCode, is vocabulary domain qualifier that allows the vocabulary domain of coded attributes to be specialized according to the geographical, organizational, or political environment where the HL7 standard is being used. It is defined as a SET<CS>data type.
typeId, is a unique identifier for an HL7 static structure that imposes constraints on an artifact. In CDA it must be defined at the root element, to indicate a CDA R2.1 document,with ClinicalDocument.typeId.root = "2.16.840.1.113883.1.3" (which is the OID for HL7 Registered models); ClinicalDocument.typeId.extension = "POCD_HD000040UV02" (which is the unique identifier for the CDA, Release Two Hierarchical Description). As CMETs are not used in CDA, this element will not be used in other classes. It is defined as a II data type.
templateId, is an optional unique identifier, which indicates to a receiver that a set of constraints have been defined for a given class and it's attributes. See section 4 on templates in CDA.
