Functional Status Assessment (FSA) Integration Profile

The Functional Status Assessment Profile (FSA) supports the handoff of assessment information between practictioners during transfers of care across enterprises.

In the context of the Continuity of Care Document, the functional status describes the patient’s status of normal functioning at the time the document was created.

Functional status includes information concerning:

  • Skin assessment
  • Physical Functioning Assessment
  • Assessment of Activities of Daily Living (bathing, feeding, dressing and grooming)
  • Pain Management
  • Mood and behavior patterns

The Institute of Medicine has determined that a high risk for medical errors occurs during the transfers of patient care between practitioners, cross-enterprise or intra-enterprise. Continuity of care requires provision of assessments to be available to the receiving practitioner for critical decision making. The transfer of physician documentation provides much of the medical/physiologic condition information. Transfer of nursing documentation provides human response (psychological, social, emotional, physiological and spiritual) of patient/family to changing conditions. Both types of documentation support continuity of patient care as each patient moves through the continuum. This profile describes how to convey functional status information using four scales which support assessments and comparison of assessments over time. This information informs caregivers making critical decisions. The functional status assessments are conveyed using medical summary documents that have been previously defined by IHE in the XDS-MS, XPHR and EDR profiles.

This profile includes an initial interoperable entry to manage continuity of care with the use of four scales which support recording of assessments and comparisons of those with prior assessments. This information provides caregivers information required for critical decision making. The profile demonstrates the collection and exchange of standardized assessment information as it is exchanged across a variety of cross-enterprise and care settings.

Options

Actor Option
Functional Status Assessment Options
Content Consumer No Options Defined

Minimum Data Set Option (1)

Note 1: At least one of these options must be implemented.

Braden Scale Option

A Content Creator Actor implementing the Braden Scale option shall generate content contain a Braden Score Assessment.

Geriatric Depression Score Option

A Content Creator Actor implementing the Geriatric Depression Score option shall generate content contain a Geriatric Depression Score Assessment.

Minimum Data Set Option

A Content Creator Actor implementing the Minimum Data Set option shall generate content contain entries from the Minimum Data Set Part G.

Coded Terminologies

This profile supports the capability to record entries beyond the IHE required coding associated with structured data. Actors from this profile may choose to utilize coded data, but interoperability at this level requires an agreement between the communicating parties that is beyond the scope of this Profile.

To facilitate this level of interoperability, the applications that implement actors within this profile shall provide a link to their HL7 conformance profile within their IHE Integration statement. The conformance profile describes the structure of the information which they are capable of creating or consuming. The conformance profile shall state which templates are supported by the application implementing the profile Actors, and which vocabularies and/or data types are used within those templates. It should also indicate the optional components of the entry that are supported.

An Example HL7 Conformance Profile is available to show how to construct such a statement. See the HL7 Refinement Constraint and Localization for more details on HL7 conformance profiles.

Content Modules

Content modules describe the content of a payload found in an IHE transaction. Content profiles are transaction neutral. They do not have dependencies upon the transaction that they appear in.

Coded Functional Status Assessment

The coded functional status assessment section contains one or more subsections that include coded functional status assessment information. This is a section content profile that is intended to be used in Medical Documents of various type, including those described in the XDS-MS, EDR, and XPHR and EDER profiles. The subsections that are defined by this content profile are further described below.

Numeric Pain Scale

Using the Numeric Pain Scale (NRS 11), a Patient rates his/her pain from 0 to 10, with 0 representing no pain and 10 representing the worst possible pain. This scale is used for age 5 years and older and is the preferred pain scale for many older healthy adults. The References section below provides more information regarding various research and evaluations of this measure.

This content profile describes how a Pain Scale assessment is reported in a CDA Document.

Braden Scale For Predicting Pressure Sore Risk

The Braden Scale For Predicting Pressure Sore Risk is a summated rating scale made up of six subscales scored from 1-3 or 4, for total scores that range from 6-23. The subscales measure impact of functional capabilities of the patient that contribute to either higher intensity and duration of pressure or lower tissue tolerance for pressure. A lower Braden Scale Score indicates lower levels of functioning and, therefore, higher levers of risk for pressure ulcer development. A copy of the Braden Scale For Predicting Pressure Sore Risk can be found in PCC TF-1/Appendix D below.

This content profile illustrates how to record the Braden Score within a CDA document.

Geriatric Depression Scale

While there are many instruments available to measure depression, the Geriatric Depression Scale (GDS), first created by Yesavage et al., (Stanford University) has been tested and used extensively with the older population. It is a brief questionnaire in which participants are asked to respond to the 30 questions by answering yes or no in reference to how they felt on the day of administration. Scores of 0 - 9 are considered normal, 10 - 19 indicate mild depression and 20 - 30 indicate severe depression. The GDS may be used with healthy, medically ill and mild to moderately cognitively impaired older adults. It has been extensively used in community, acute and long-term care settings. As for evidence-based research the GDS was found to have 92% sensitivity and 89% specificity when evaluated against diagnostic criteria per the Hartford Institute for Geriatric Nursing. The validity and reliability of the tool have been supported through both clinical practice and research.

This content profile illustrates how to record the Geriatric Depression Scale within a CDA document.

Physical Function

The Minimum Data Set for Long Term Care Version 2.0 (MDS 2.0) is a federally mandated (in the United States) standard assessment form. This instrument is specified by the Centers for Medicare and Medicaid Services, and requires nursing facilities to conduct a comprehensive, accurate, standardized, reproducible assessment of each resident’s functional capacity. Section G Physical Functioning and Structural Problems are included in this profile. More information is found at[1].

Process Flow

Three use cases are described in futher detail below.

  1. Long-Term Care to Acute Care - describes a use case for assessment information during transfers of care from long term to acute care.
  2. Home or Ambulatory Care into Acute Care - describes a use case for assessment information during multiple care transfers.
  3. Behavioral - describes a use case for assessment information during transfers of care where information about depression in an older patient is used.

Content Consumer 
A Content Consumer Actor is responsible for viewing, import, or other processing of content created by a Content Creator Actor.
Clinical Data Consumer 
A clinical data consumer makes use of clinical patient data.
Clinical Data Source 
A Clinical Data Sources maintains patient information about vital signs, problem and allergies, results from diagnostic tests (e.g., Lab, Imaging, or other test results), medications, immunizations or historical or planned visits and procedures.

Appendix B - Transaction Descriptions

Transactions are interactions between actors that transfer the required information through standards-based messages. The PCC Technical Framework does not define any specific transactions, as these are assumed to be carried out through the use of transactions defined in other IHE Profiles.

Query Existing Data 
Request information about recent patient information, used to obtain vital signs measurements, problems and allergies, diagnostic results, medications, immunizations, or procedures or visits relevant for a patient. The query may request information about some or all of the above topics, or may request information on a specific topic, or one entered for a specific encounter or date range.


Appendix C - How to Prepare an IHE Integration Statement

IHE Integration Statements are documents prepared and published by vendors to describe the conformance of their products with the IHE Technical Framework. They identify the specific IHE capabilities a given product supports in terms of IHE actors and integration profiles described in the technical frameworks of each domain.

Users familiar with these concepts can use Integration Statements to determine what level of integration a vendor asserts a product supports with complementary systems and what clinical and operational benefits such integration might provide. Integration Statements are intended to be used in conjunction with statements of conformance to specific standards (e.g. HL7, IETF, DICOM, W3C, etc.).

IHE provides a process for vendors to test their implementations of IHE actors and integration profiles. The IHE testing process, culminating in a multi-party interactive testing event called the Connect-a-thon, provides vendors with valuable feedback and provides a baseline indication of the conformance of their implementations. The process is not intended to independently evaluate, or ensure, product compliance. In publishing the results of the Connect-a-thon and facilitating access to vendors' IHE Integration Statements, IHE and its sponsoring organizations are in no way attesting to the accuracy or validity of any vendor's IHE Integration Statements or any other claims by vendors regarding their products.

IMPORTANT -- PLEASE NOTE: Vendors have sole responsibility for the accuracy and validity of their IHE Integration Statements. Vendors' Integration Statements are made available through IHE simply for consideration by parties seeking information about the integration capabilities of particular products. IHE and its sponsoring organizations have not evaluated or approved any IHE Integration Statement or any related product, and IHE and its sponsoring organizations shall have no liability or responsibility to any party for any claims or damages, whether direct, indirect, incidental or consequential, including but not limited to business interruption and loss of revenue, arising from any use of, or reliance upon, any IHE Integration Statement.

Structure and Content of an IHE Integration Statement

An IHE Integration Statement for a product shall include:

  1. The Vendor Name
  2. The Product Name (as used in the commercial context) to which the IHE Integration Statement applies.
  3. The Product Version to which the IHE Integration Statement applies.
  4. A publication date and optionally a revision designation for the IHE Integration Statement.
  5. The following statement: "This product implements all transactions required in the IHE Technical Framework to support the IHE Integration Profiles, Actors and Options listed below:"
  6. A list of IHE Integration Profiles supported by the product and, for each Integration Profile, a list of IHE Actors supported. For each integration profile/actor combination, one or more of the options defined in the IHE Technical Framework may also be stated. Profiles, Actors and Options shall use the names defined by the IHE Technical Framework Volume I. (Note: The vendor may also elect to indicate the version number of the Technical Framework referenced for each Integration Profile.)

Note that implementation of the integration profile implies implementation of all required transactions for an actor as well as selected options.

The statement shall also include references and/or internet links to the following information:

  1. Specific internet address (or universal resource locator [URL]) where the vendor's Integration Statements are posted
  2. URL where the vendor's standards conformance statements (e.g., HL7, DICOM, etc.) relevant to the IHE transactions implemented by the product are posted.
  3. URL of the IHE Initiative's web page for general IHE information www.himss.org/ihe.

An IHE Integration Statement is not intended to promote or advertise aspects of a product not directly related to its implementation of IHE capabilities.

Format of an IHE Integration Statement

Each Integration Statement shall follow the format shown below. Vendors may add a cover page and any necessary additional information in accordance with their product documentation policies.

The IHE Product Registry

The assumption of an integration statement is that all actors listed are functionally grouped and conform to any profile specifications for such groupings. In case of exceptions the vendor must explicitly describe the functional groupings.

IHE has developed a new Web-based database of Integration Statements. The IHE Product Registry enables developers to create, manage and publish Integration Statements for their commercial and open source healthcare IT systems. It allows users to browse for these systems based on their conformance with specific IHE Actors and Profiles. The system is open for use by developers and users now!

IHE Transactions

This section defines each IHE transaction in detail, specifying the standards used, and the information transferred.

Cross Enterprise Document Content Transactions

At present, all transactions used by the PCC Content Profiles appear in ITI TF-2. General Options defined in content profiles for a Content Consumer are described below.

View Option

A Content Consumer that supports the View Option shall be able to:

  1. Use the appropriate XD* transactions to obtain the document along with associated necessary metadata.
  2. Render the document for viewing. This rendering shall meet the requirements defined for CDA Release 2 content presentation semantics (See Section 1.2.4 of the CDA Specification: Human readability and rendering CDA Documents). CDA Header information providing context critical information shall also be rendered in a human readable manner. This includes at a minimum the ability to render the document with the stylesheet specifications provided by the document source, if the document source provides a stylesheet. Content Consumers may optionally view the document with their own stylesheet, but must provide a mechanism to view using the source stylesheet.
  3. Support traversal of links for documents that contain links to other documents managed within the sharing framework.
  4. Print the document to paper.
Document Import Option

This Option requires that the View Option be supported. In addition, the Content Consumer that supports the Document Import Option shall be able to support the storage of the entire document (as provided by the sharing framework, along with sufficient metadata to ensure its later viewing) both for discharge summary or referral documents. This Option requires the proper tracking of the document origin. Once a document has been imported, the Content Consumer shall offer a means to view the document without the need to retrieve it again from the sharing framework. When viewed after it was imported, a Content Consumer may chose to access the sharing framework to find out if the related Document viewed has been deprecated, replaced or addended.


Note: For example, when using XDS, a Content Consumer may choose to query the Document Registry about a document previously imported in order to find out if this previously imported document may have been replaced or has received an addendum. This capability is offered to Content Consumers by this Integration Profile, but not required, as the events that may justify such a query are extremely implementation specific.


Section Import Option

This Option requires that the View Option be supported. In addition, the Content Consumer that supports the Section Import Option shall be able to support the import of one or more sections of the document (along with sufficient metadata to link the data to its source) both for discharge summary or referral. This Option requires the proper tracking of the document section origin. Once sections have been selected, a Content Consumer shall offer a means to copy the imported section(s) into local data structures as free text. This is to support the display of section level information for comparison or editing in workflows such as medication reconciliation while discrete data import is not possible. When viewed again after it is imported, a Content Consumer may chose to access the sharing framework to find out if the related information has been updated.


Note: For example, when using XDS, a Content Consumer may choose to query the Document Registry about a document whose sections were previously imported in order to find out if this previously imported document may have been replaced or has received an addendum. This capability is offered to Content Consumers by this Integration Profile, but not required, as the events that may justify such a query are extremely implementation specific.


This Option does not require, but does not exclude the Content Consumer from offering a means to select and import specific subsets of the narrative text of a section.

Discrete Data Import Option

This Option does not require that the View, Import Document or Section Import Options be supported. The Content Consumer that supports the Discrete Data Import Option shall be able to support the storage of the structured content of one or more sections of the document. This Option requires that the user be offered the possibility to select among the specific sections that include structured content a set of clinically relevant record entries (e.g. a problem or an allergy in a list) for import as part of the local patient record with the proper tracking of its origin.


Note: The Discrete Data Import Option does not require the support of the View, Import Document or Import Sections Options so that it could be used alone to support implementations of Content Consumers such as Public Health Data or Clinical Research systems that might aggregate and anonymize specific population healthcare information data as Document Consumer Actors, but one where no care provider actually views the medical summaries.


When discrete data is accessed after it was imported, a Content Consumer may choose to check if the document related to the discrete data viewed has been deprecated, replaced or addended.

A Content Consumer Actor grouped with the XDS Document Source Actor may query the Document Registry about a document from which discrete data was previously imported in order to find out if this previously imported document may have been replaced or has received an addendum. This capability is offered to Content Consumers by this Integration Profile, but not required, as the events that may justify such a query are extremely implementation specific.

IHE Patient Care Coordination Bindings

This section describes how the payload used in a transaction of an IHE profile is related to and/or constrains the data elements sent or received in those transactions. This section is where any specific dependencies between the content and transaction are defined.

A content integration profile can define multiple bindings. Each binding should identify the transactions and content to which it applies.

The source for all required and optional attributes have been defined in the bindings below. Three tables describe the three main XDS object types: XDSDocumentEntry, XDSSubmissionSet, and XDSFolder. XDSSubmissionSet and XDSDocumentEntry are required. Use of XDSFolder is optional. These concepts are universal to XDS, XDR and XDM.

The columns of the following tables are:

  • <XXX> attribute – name of an XDS attribute, followed by any discussion of the binding detail.
  • Optional? - Indicates the required status of the XDS attribute, and is one of R, R2, or O (optional). This column is filled with the values specified in the XDS Profile as a convenience.
  • Source Type – Will contain one of the following values:
Source Type Description
SA Source document Attribute – value is copied directly from source document. The Source/Value column identifies where in the source document this attribute comes from. Specify the location in XPath when possible.
SAT Source document Attribute with Transformation – value is copied from source document and transformed. The Source/Value column identifies where in the source document this attribute comes from. Specify the location in XPath when possible. Extended Discussion column must not be empty and the transform must be defined in the extended discussion
FM Fixed (constant) by Mapping - for all source documents. Source/Value column contains the value to be used in all documents.
FAD Fixed by Affinity Domain – value configured into Affinity Domain, all documents will use this value.
CAD Coded in Affinity Domain – a list of acceptable codes are to be configured into Affinity Domain. The value for this attribute shall be taken from this list.
CADT Coded in Affinity Domain with Transform - a list of acceptable codes are to be configured into Affinity Domain. The value for this attribute shall be taken from this list.
n/a Not Applicable – may be used with an optionality R2 or O attribute to indicate it is not to be used.
DS Document Source – value comes from the Document Source actor. Use Source/Value column or Extended Discussion to give details.
O Other – Extended Discussion must be 'yes' and details given in an Extended Discussion.
  • Source/Value – This column indicates the source or the value used.

The following tables are intended to be summaries of the mapping and transforms. The accompanying sections labeled 'Extended Discussion' are to contain the details as necessary.

Medical Document Binding to XDS, XDM and XDR

This binding defines a transformation that generates metadata for the XDSDocumentEntry element of appropriate transactions from the XDS, XDM and XDR profiles given a medical document and information from other sources. The medical document refers to the document being stored in a repository that will be referenced in the registry. The other sources of information include the configuration of the Document Source actor, the Affinity Domain, the site or facility, local agreements, other documents in the registry/repository, and this Content Profile.

In many cases, the CDA document is created for the purposes of sharing within an affinity domain. In these cases the context of the CDA and the context of the affinity domain are the same, in which case the following mappings shall apply.

In other cases, the CDA document may have been created for internal use, and are subsequentyly being shared. In these cases the context of the CDA document would not neccessarily coincide with that of the affinity domain, and the mappings below would not necessarily apply.

Please note the specifics given in the table below.

mimeType R FM text/xml
parentDocumentRelationship R
(when applicable)
DS Local document versions need not always be published, and so no exact mapping can be determined from the content of the CDA document.
The parentDocumentRelationship may be determined in some configurations from the relatedDocument element present in the CDA dsocument. If the context of the CDA coincides with that of the affinity domain, then the following x-path may be appropriate:
/ClinicalDocument/relatedDocument/@typeCode
parentDocumentId R
(when parent
Document
Relationship is present)
DS Local document versions need not always be published, and so no exact mapping can be determined from the content of the CDA document.
The parentDocumentId may be determined in some configurations from the relatedDocument element present in the CDA dsocument. If the context of the CDA coincides with that of the affinity domain, then the following x-path may be appropriate:

The parentDocumentId can be formatted using the following XPath expression, where $docID in the expression below represents the identifier.
concat($docID/@root,"^", $docID/@extension)

patientId R DS The XDS Affinity Domain patient ID can be mapped from the patientRole/id element using transactions from the ITI PIX or PDQ profiles. See sourcePatientId below. If the context of the CDA coincides with that of the affinity domain, then the following x-path may be appropriate:


$patID <= /ClinicalDocument/recordTarget/
patientRole/id

practiceSettingCode R CAD This elements should be based on a coarse classification system for the class of specialty practice. Recommend the use of the classification system for Practice Setting, such as that described by the Subject Matter Domain in LOINC.
practiceSettingCodeDisplayName R CAD This element shall contain the display names associated with the codes described above.
serviceStartTime R2 SAT /ClinicalDocument/documentationOf/
serviceEvent/effectiveTime/low/
@value


Times specified in clinical documents may be specified with a precision in fractional sections, and may contain a time zone offset. In the XDS Metadata, it can be precise to the second, and is always given in UTC, so the timezone offset if present must be added to the current time to obtain the UTC time.

serviceStopTime R2 SAT /ClinicalDocument/documentationOf/
serviceEvent/effectiveTime/high/
@value


Times specified in clinical documents may be specified with a precision in fractional sections, and may contain a time zone offset. In the XDS Metadata, it can be precise to the second, and is always given in UTC, so the timezone offset if present must be added to the current time to obtain the UTC time.

sourcePatientId R SAT $patID <= /ClinicalDocument/recordTarget/

patientRole


The sourcePatientInfo metadata element can be assembled from various components of the patientRole element in the clinical document.

title O SA /ClinicalDocument/title
typeCode R CADT /ClinicalDocument/code/@code


The typeCode should be mapped from the ClinicalDocument/code element to a set of document type codes configured in the affinity domain. One suggested coding system to use for typeCode is LOINC, in which case the mapping step can be omitted.

typeCodeDisplay
Name
R CADT /ClinicalDocument/code/@displayName
uniqueId R SAT $docID <= /ClinicalDocument/id


The uniqueId can be formatted using the following XPath expression, where $docID in the expression below represents the identifier.
concat($docID/@root,"^", $docID/@extension)

XDSSubmissionSet Metadata

The submission set metadata is as defined for XDS, and is not necessarily affected by the content of the clinical document. Metadata values in an XDSSubmissionSet with names identical to those in the XDSDocumentEntry may be inherited from XDSDocumentEntry metadata, but this is left to affinity domain policy and/or application configuration.

Use of XDS Submission Set

This content format uses the XDS Submission Set to create a package of information to send from one provider to another. All documents referenced by the Medical Summary in this Package must be in the submission set.

Use of XDS Folders

No specific requirements identified.

Configuration

IHE Content Profiles using this binding require that Content Creators and Content Consumers be configurable with institution and other specific attributes or parameters. Implementers should be aware of these requirements to make such attributes easily configurable. There shall be a mechanism for the publishing and distribution of style sheets used to view clinical documents.

Extensions from other Domains

Scanned Documents (XDS-SD)

XDS-SD is a CDA R2 document and thus conforms to the XDS Metadata requirements in the PCC-TF, volume 2, Section 5 unless otherwise specified below.

XDSDocumentEntry

XDS-SD leverages the XDS DocumentEntry Metadata requirements in the PCC-TF, volume 2, Section 5.1.1.1.1 and in PCC_TF-2/Bindings unless otherwise specified below

XDSDocumentEntry.formatCode

The XDSDocumentEntry.formatCode shall be urn:ihe:iti:xds-sd:pdf:2008 when the document is scanned pdf and urn:ihe:iti:xds-sd:text:2008 when the document is scanned text. The formatCode codeSystem shall be 1.3.6.1.4.1.19376.1.2.3.

XDSDocumentEntry.uniqueId

This value shall be the ClinicalDocument/id in the HL7 CDA R2 header. The root attribute is required, and the extension attribute is optional. In accordance with the XDS.a profile, total length is limited to 128 characters; for XDS.b the limit is 256 characters. Additionally see PCC-TF, volume 2, Section 5.1.1.1.1 or PCC_TF-2/Bindings for further content specification.

Relating instances of XDS-SD documents

In general, most instances of XDS-SD will not have parent documents. It is possible, however, in some specific use cases that instances of XDS-SD documents are related. For example, for a particular document it may be the case that both the PDF scanned content and somewhat equivalent plaintext need to be wrapped and submitted. Each document would correspond to separate XDSDocumentEntries linked via an XFRM Association that indicates one document is a transform of the other. These can be submitted in a single submission set, or in separate ones. Other specific examples may exist and this profile does not preclude the notion of a parent document for these cases.

XDSSubmissionSet

No additional constraints. Particular to this profile, a legitimate use of submission sets would be to maintain a logical grouping of multiple XDS-SD documents. We encourage such usage. For more information, see PCC-TF-2 Section 5.1.1.1.2 or PCC_TF-2/Bindings.

XDSFolder

No additional requirements. For more information, see PCC-TF-2 Section 5.1.1.1.3 or PCC_TF-2/Bindings.

Basic Patient Privacy Consents (BPPC)

Laboratory Reports (XD-LAB)

XD-Lab is a CDA R2 document and thus conforms to the XDS Metadata requirements in the PCC-TF, volume 2, Section 5 unless otherwise specified below.

XDSDocumentEntry

XD-Lab leverages the XDS DocumentEntry Metadata requirements in the PCC-TF, volume 2, Section 5.1.1.1.1 and in PCC_TF-2/Bindings unless otherwise specified below

XDSDocumentEntry.eventCodeList

XD-Lab documents further constrain the the XDSDocumentEntry.eventCodeList to the following.

XDSDocumentEntry
Attribute Optional? Source Type Source/ Value
eventCodeList R2 SAT ClinicalDocument / component / structuredBody / component / section / entry / act / entryRelationship / organizer (templateId="1.3.6.1.4.1.19376.1.3.1.1")/ component / observation(templateId="1.3.6.1.4.1.19376.1.3.1.1.1")/code

AND

ClinicalDocument / component / structuredBody / component / section / entry / act / subject / code

If the document has Reportable Condition, then this code shall be among those listed in the eventCodeList. Additionally, if the document contains information about a Non-Human Subject, then the code that indicates what this subject is shall be among those listed in the eventCodeList. Thus, this attribute has been enhanced from the XDS profile from O to R2.

XDSDocumentEntry.formatCode

The XDSDocumentEntry.formatCode shall be urn:ihe:lab:xd-lab:2008 The formatCode codeSystem shall be 1.3.6.1.4.1.19376.1.2.3.

XDSSubmissionSet

No additional constraints. For more information, see PCC-TF-2 Section 5.1.1.1.2 or PCC_TF-2/Bindings.

XDSFolder

No additional requirements. For more information, see PCC-TF-2 Section 5.1.1.1.3 or PCC_TF-2/Bindings.

PINSTRUCT This is the act of providing instructions to a patient regarding the use of medication.
FINSTRUCT This is the act of providing instructions to the supplier regarding the fulfillment of the medication order.
IMMUNIZ The act of immunization of a patient using a particular substance or class of substances identified using a specified vocabulary. Use of this vocabulary term requires the use of either the SUBSTANCE or SUBSTCLASS qualifier described below, along with an identified substance or class of substances.
DRUG The act of treating a patient with a particular substance or class of substances identified using a specified vocabulary. Use of this vocabulary term requires the use of either the SUBSTANCE or SUBSTCLASS qualifier described below, along with an identified substance or class of substances.
INTOL An observation that a patient is somehow intollerant of (e.g., allergic to) a particular substance or class of substances using a specified vocabulary. Use of this vocabulary term requires the use of either the SUBSTANCE or SUBSTCLASS qualifier described below, along with an identified substance or class of substances.
SUBSTANCE A qualifier that identifies the substance used to treat a patient in an immunization or drug treatment act. The substance is expected to be identified using a vocabulary such as RxNORM, SNOMED CT or other similar vocabulary and should be specific enough to identify the ingredients of the substance used.
SUBSTCLASS A qualifier that identifies the class of substance used to treat a patient in an immunization or drug treatment act. The class of substances is expected to be identified using a vocabulary such as NDF-RT, SNOMED CT or other similar vocabulary, and should be broad enough to classify substances by mechanism of action (e.g., Beta Blocker), intended effect (Dieuretic, antibiotic) or ...

Appendix B - Validating CDA Documents using the Framework

Many of the constraints specified by the content modules defined in the PCC Technical Framework can be validated automatically by software. Automated validation is a very desirable capability, as it makes it easier for implementers to test the correctness of their implementations. With regard to validation of the content module, the PCC Technical Framework narrative is the authoritative specification, not any automated software tool. Having said that, it is still very easy to create a validation framework for the IHE PCC Technical Framework using a XML validation tool such as Schematron. Since each content module has a name (the template identifier), any XML instance that reports itself to be of that "class" can be validated by creating assertions that must be true for each constraint indicated for the content module. In the XML representation, the <templateId> element is a child of the element that is claiming conformance to the template named. Thus the general pattern of a Schematron that validates a specific template is shown below:

<schema xmlns="http://www.ascc.net/xml/schematron" xmlns:cda="urn:hl7-org:v3">
  <ns prefix="cda" uri="urn:hl7-org:v3" />
  <pattern name='ReferralSummary'>
    <rule context='*[cda:templateId/@root="1.3.6.1.4.1.19376.1.5.3.1.1.3]"'>
      <!-- one or more assertions made by the content module -->
    </rule>
  </pattern>
</schema>

Validating Documents

For document content modules, the pattern can be extended to support common document content module constraints as shown below:

<schema xmlns="http://www.ascc.net/xml/schematron" xmlns:cda="urn:hl7-org:v3">
  <ns prefix="cda" uri="urn:hl7-org:v3" />
  <pattern name='ReferralSummary'>
    <rule context='*[templateId/@root="1.3.6.1.4.1.19376.1.5.3.1.1.3]"'>
      <!-- Verify that the template id is used on the appropriate type of object -->
      <assert test='../ClinicalDocument'>
        Error: The referral content module can only be used on Clinical Documents.
      </assert>
      <!-- Verify that the parent templateId is also present. -->
      <assert test='templateId[@root="1.3.6.1.4.1.19376.1.5.3.1.1.2"]'>
        Error: The parent template identifier for medical summary is not present.
      </assert>
      <!-- Verify the document type code -->
      <assert test='code[@code = "34133-9"]'>
        Error: The document type code of a referral summary must be
        34133-9 SUMMARIZATION OF EPISODE NOTE.
      </assert>
      <assert test='code[@codeSystem = "2.16.840.1.113883.6.1"]'>
        Error: The document type code must come from the LOINC code 
        system (2.16.840.1.113883.6.1).
      </assert>
      <!-- Verify that all required data elements are present -->
      <assert test='.//templateId[@root = "1.3.6.1.4.1.19376.1.5.3.1.3.1"]'>
        Error: A referral summary must contain a reason for referral.
      </assert>
      <!-- Alert on any missing required if known elements -->
      <assert test='.//templateId[@root = "1.3.6.1.4.1.19376.1.5.3.1.3.8"]'>
        Warning: A referral summary should contain a list of history of past illnesses.
      </assert>
      <!-- Note any missing optional elements -->
      <assert test='.//templateId[@root = "1.3.6.1.4.1.19376.1.5.3.1.3.18"]'>
        Note: This referral summary does not contain the pertinent review of systems.
      </assert>
    </rule>
  </pattern>
</schema>

Validating Sections

The same pattern can be also applied to sections with just a few minor alterations.

<schema xmlns="http://www.ascc.net/xml/schematron" xmlns:cda="urn:hl7-org:v3">
  <ns prefix="cda" uri="urn:hl7-org:v3" />
  <pattern name='ReasonForReferralUncoded'>
    <rule context='*[templateId/@root="1.3.6.1.4.1.19376.1.5.3.1.3.1"]'>
      <!-- Verify that the template id is used on the appropriate type of object -->
      <assert test='section'>
        Error: The coded reason for referral module can only be used on a section.
      </assert>
      <assert test='false'>
        Manual: Manually verify that this section contains narrative providing the
        reason for referral.
      </assert>
      <!-- Verify that the parent templateId is also present. -->
      <assert test='templateId[@root="1.3.6.1.4.1.19376.1.5.3.1.3.1"]'>
        Error: The parent template identifier for the reason for referral 
        module is not present.
      </assert>
      <!-- Verify the section type code -->
      <assert test='code[@code = "42349-1"]'>
        Error: The section type code of the reason for referral section must be 42349-1
        REASON FOR REFERRAL.
      </assert>
      <assert test='code[@codeSystem = "2.16.840.1.113883.6.1"]'>
        Error: The section type code must come from the LOINC code 
        system (2.16.840.1.113883.6.1).
      </assert>
  </pattern>
  <pattern name='ReasonForReferralCoded'>
    <rule context='*[templateId/@root="1.3.6.1.4.1.19376.1.5.3.1.3.2"]'>
      <!-- The parent template will have already verified the type of object -->
      <!-- Verify that the parent templateId is also present. -->
      <assert test='templateId[@root="1.3.6.1.4.1.19376.1.5.3.1.3.1"]'>
        Error: The parent template identifier for the reason for referral 
        module is not present.
      </assert>
      <!-- Don't bother with the section type code, as the parent template caught it -->
      <!-- Verify that all required data elements are present -->
      <assert test='.//templateId[@root = "1.3.6.1.4.1.19376.1.5.3.1.4.13"]'>
        Error: A coded reason for referral section must contain an simple observation.
      </assert>
      <!-- Alert on any missing required if known elements -->
      <!-- Note any missing optional elements -->
    </rule>
  </pattern>
</schema>

A similar pattern can also be followed for Entry and Header content modules, and these are left as an exercise for the reader.

Phases of Validation and Types of Errors

Note that each message in the Schematrons shown above start with a simple text string that indicates whether the message indicates one of the following conditions:

  • An error, e.g., the failure to transmit a required element,
  • A warning, e.g., the failure to transmit a required if known element,
  • A note, e.g., the failure to transmit an optional element.
  • A manual test, e.g., a reminder to manually verify some piece of content.

Schematron supports the capability to group sets of rules into phases by the pattern name, and to specify which phases of validation should be run during processing. To take advantage of this capability, one simply breaks each <pattern> element above up into separate patterns depending upon whether the assertion indicates an error, warning, note or manual test, and then associate each pattern with a different phase. This is shown in the figure below.

<schema xmlns="http://www.ascc.net/xml/schematron" xmlns:cda="urn:hl7-org:v3">

      </assert>
    </rule>
  </pattern>
</schema>

Using these simple "templates" for template validation one can simply create a collection of Schematron patterns that can be used to validate the content modules in the PCC Technical Framework. Such Schematrons are expected to be made available as part of the MESA test tools that are provided to IHE Connectathon participants, and which will also be made available to the general public after connectathon.

Appendix C - Extensions to CDA Release 2.0

This section describes extensions to CDA Release 2.0 that are used by the IHE Patient Care Coordination Technical Framework.

IHE PCC Extensions

All Extensions to CDA Release 2.0 created by the IHE PCC Technical Committee are in the namespace urn:ihe:pcc:hl7v3.

The approach used to create extension elements created for the PCC Technical Framework is the same as was used for the HL7 Care Record Summary (see Appendix E) and the ASTM/HL7 Continuity of Care Document (see secion 7.2).

replacementOf

The <replacementOf> extension element is applied to a section appearing in a PHR Update Document to indicate that that section's content should replace that of a previously existing section. The identifier of the previously existing section is given so that the PHR Manager receiving the Update content will know which section to replace. The model for this extension is shown below.

Model for replacementOf

Use of this extension is shown below. The <replacementOf> element appears after all other elements within the <section> element. The <id> element appearing in the <externalDocumentSection> element shall provide the identifier of the section being replaced in the parent document.

Example use of the replacementOf extension
<section>
 <id root=' ' extension=' '/>
 <code code=' ' codeSystem='2.16.840.1.113883.6.1' codeSystemName='LOINC'/>
 <title>Name of the Section</title>
 <text>Text of the section</text>
 <entry></entry>
 <component></component>
 <pcc:replacementOf xmlns:pcc='urn:ihe:pcc:hl7v3'>
   <pcc:externalDocumentSection>
     <pcc:id root='58FCBE50-D4F2-4bda-BC1C-2105B284BBE3'/>
   <pcc:externalDocumentSection/>
 </pcc:replacementOf>
</section>

Extensions Defined Elsewhere used by IHE PCC

Entity Identifiers

There is often a need to record an identifer for an entity so that it can be subsequently referenced. This extension provides a mechnism to store that identifier. The element appears after any <realm>, <typeId> or <templateId> elements, but before all others in the entity where it is used:

<playingEntity classCode='ENT' determinerCode='INSTANCE'>
 <sdtc:id root='1.3.6.4.1.4.1.2835.2' extension='EntityID'/>
   :
   .
</playingEntity>

Patient Identifier

There is a need to record the identifer by which a patient is known to another healthcare provider. This extension provides a role link between the assigned, related or associated entity, and the patient role.

Use of this extension to record the identifier under which the patient is known to a provider is shown below.

Example use of the Patient Identifier Extension
<assignedEntity>
 <id extension='1' root='1.3.6.4.1.4.1.2835.1'/>
 <code code='59058001'
   codeSystem='2.16.840.1.113883.6.96'
   codeSystemName='SNOMED CT'
   displayName='General Physician'/>
 <addr>
   <streetAddressLine>21 North Ave</streetAddressLine>
   <city>Burlington</city>
   <state>MA</state>
   <postalCode>01803</postalCode>
   <country>USA</country>
 </addr>
 <telecom value='tel:(999)555-1212' use='WP'/>
 <assignedPerson>
   <name>
     <prefix>Dr.</prefix><given>Bernard</given><family>Wiseman</family><suffix>Sr.</suffix>
   </name>
 </assignedPerson>
 <sdtc:patient xmlns:sdtc='urn:hl7-org:sdtc' >
   <sdtc:id root='1.3.6.4.1.4.1.2835.2' extension='PatientMRN'/>
 </sdtc:patient>
</assignedEntity>

The <patient> element records the link between the related, assigned or associated entity and the patient. The <id> element provides the identifier for the patient. The root attribute of the <id> should be the namespace used for patient identifiers by the entity. The extension attribute of the <id> element shall be the patient's medical record number or other identifier used by the entity to identify the patient.
