Emergency Department Referral (EDR) Integration Profile
Physicians frequently determine that patients either onsite, or calling in, should proceed directly to an emergency department for care. The referring physician has valuable data that can inform ED providers, including the history of the current problem, past medical problems, medications, allergies, and frequently a concrete assessment and plan for the patient such as hospital admission. Unfortunately, this information is inconsistently relayed to the ED provider who ultimately cares for the patient. Currently, this transfer of care requires verbal transfer of extensive information. Unfortunately, the ED provider recording the information may not be the person who will ultimately care for the patient, may not document sufficient detail, or may forget to document any information at all.
Loss of this data can lead to costly over-testing in the ED, or worse, an inappropriate disposition for the patient.
Using an EHR, an ED Referral is created; including the nature of the current problem, past medical history, and medications. Upon arrival of the patient to the ED, the patient is identified as a referral, and the transfer document is incorporated into the EDIS.
This profile may be used to cover a wide variety of ED referral situations, for example, primary care provider to ED Referral, Long term care to ED referral, or even ED to ED referral (as in the case of transfer from a level 2 Critical care facility to a level 1 facility).
There are two actors in the EDR profile, the Content Creator and the Content Consumer. Content is created by a Content Creator and is to be consumed by a Content Consumer. The sharing or transmission of content from one actor to the other is addressed by the appropriate use of IHE profiles described below, and is out of scope of this profile. A Document Source or a Portable Media Creator may embody the Content Creator Actor. A Document Consumer, a Document Recipient or a Portable Media Importer may embody the Content Consumer Actor. The sharing or transmission of content or updates from one actor to the other is addressed by the use of appropriate IHE profiles described in the section on Content Bindings with XDS, XDM and XDR.
|Content Consumer||View Option (1)|
|Document Import Option (1)|
|Section Import Option (1)|
|Discrete Data Import Option (1)|
Content Consumer Options
This option defines the processing requirements placed on Content Consumers for providing access, rendering and management of the medical document. See the View Option in PCC TF-2 for more details on this option.
A Content Creator Actor should provide access to a style sheet that ensures consistent rendering of the medical document content as was displayed by the Content Consumer Actor.
The Content Consumer Actor shall be able to present a view of the document using this style sheet if present.
Document Import Option
This option defines the processing requirements placed on Content Consumers for providing access, and importing the entire medical document and managing it as part of the patient record. See the Document Import Option in PCC TF-2 for more details on this option.
Section Import Option
This option defines the processing requirements placed on Content Consumers for providing access to, and importing the selected section of the medical document and managing them as part of the patient record. See the Section Import Option in PCC TF-2 for more details on this option.
Discrete Data Import Option
This option defines the processing requirements placed on Content Consumers for providing access, and importing discrete data from selected sections of the medical document and managing them as part of the patient record. See the Discrete Data Import Option in PCC TF-2 for more details on this option.
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.
ED Referral Document Content Module
An ED Referral content document is a type of referral summary, and incorporates the constraints defined for referral summaries found in Referral Summary. In addition, the ED Referral content profile includes additional information to support recording the mode of transportation, estimated time of arrival, and proposed disposition.
ED Referral Process Flow
Use Case 1: Provider to Emergency Department Referral
This use case involves a "collaborative" transfer of care for the referral of a patient from a care provider to the emergency department. This use case is a central component of an "e-referral" process, which typically requires an appropriate level of agreement and collaboration between the two parties prior to the actual transfer of clinical information being initiated.
Preconditions: The referring provider has an EMR system with capability to write notes and manage data elements, and share information. The specific data elements managed by the providers EMR are expected to be the source for the information used in creating the medical summary document related to this transfer of care. A variety of EMR implementations and usage by clinicians may result in some variability in the content of the medical summary. The receiving ED provider has an EDIS system with the capability to share information.
Events: A provider sees a patient, or has spoken with the patient or a family member, and has decided to refer the patient to an ED. The provider creates an ED Referral summary document, and shares it. The detailed content of the medical summary to support this use case is detailed as part of the document content profile specification.
Post conditions: The ED specialist physician retrieve the Documents and views them, optionally importing data. Import assumes the specialist has an EDIS system with the capability for managing those discrete data elements.
Steps to identify the ED and obtain insurance preauthorization have been placed out of scope for this Integration Profile.
Grouping with other Profiles
Cross Enterprise Document Sharing, Media Interchange and Reliable Messages
Actors from the ITI XDS, XDM and XDR profiles embody the Content Creator and Content Consumer sharing function of this profile. A Content Creator or Content Consumer may be grouped with appropriate actors from the XDS, XDM or XDR profiles to exchange the content described therein. The metadata sent in the document sharing or interchange messages has specific relationships or dependencies (which we call bindings) to the content of the clinical document described in the content profile.
The Patient Care Coordination Technical Framework defines the bindings to use when grouping the Content Creator of this Profile with actors from the IHE ITI XDS, XDM or XDR Integration Profiles.
|ED Referral||Medical Document Binding to XDS, XDM and XDR||Content Creator||R|

Appendix A - Actor Descriptions
Actors are information systems or components of information systems that produce, manage, or act on information associated with operational activities in the enterprise.
- Content Creator
- The Content Creator Actor is responsible for the creation of content and transmission to a Content Consumer.
- 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:
- The Vendor Name
- The Product Name (as used in the commercial context) to which the IHE Integration Statement applies.
- The Product Version to which the IHE Integration Statement applies.
- A publication date and optionally a revision designation for the IHE Integration Statement.
- 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:"
- 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:
- Specific internet address (or universal resource locator [URL]) where the vendor's Integration Statements are posted
- URL where the vendor's standards conformance statements (e.g., HL7, DICOM, etc.) relevant to the IHE transactions implemented by the product are posted.
- 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.
|IHE Integration Statement||Date||12 Oct 2005|

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!

Technical Framework Supplement
- (PCC TF-2/Preface)Preface
- (PCC TF-2/Introduction)Introduction
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.
A Content Consumer that supports the View Option shall be able to:
- Use the appropriate XD* transactions to obtain the document along with associated necessary metadata.
- 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.
- Support traversal of links for documents that contain links to other documents managed within the sharing framework.
- 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:
|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.
|XDSDocumentEntry Attribute||Optional?||Source Type||Source/ Value|
$person <= /ClinicalDocument/author
|authorRole||R2||SAT||This metadata element should be based on a mapping of the participation function defined in the CDA document to the set of author roles configured for the affinity domain. If the context of the CDA coincides with that of the affinity domain, then the following x-path may be appropriate: |
|authorSpecialty||R2||SAT||This metadata element should be based on a mapping of the code associated with the assignedAuthor to detailed defined classification system for healthcare providers such configured in the affinitity domain. Possible classifications include those found in SNOMED-CT, or the HIPAA Healthcare Provider Taxonomy. If the context of the CDA coincides with that of the affinity domain, then the following x-path may be appropriate: |
|classCode||R||CADT||Derived from a mapping of /ClinicalDocument/code/@code to an Affinity Domain specified coded value to use and coding system. Affinity Domains are encouraged to use the appropriate value for Type of Service, based on the LOINC Type of Service (see Page 53 of the LOINC User's Manual). Must be consistent with /ClinicalDocument/code/@code|
|classCodeDisplayName||R||CADT||DisplayName of the classCode derived. Derived from a mapping of /ClinicalDocument/code/@code to the appropriate Display Name based on the Type of Service. Must be Consitent with /ClinicalDocument/code/@code|
|confidentialityCode||R||CADT||Derived from a mapping of /ClinicalDocument/confidentialityCode/@code to an Affinity Domain specified coded value and coding system. When using the BPPC profile, the confidentialyCode may also be obtained from the <authorization> element.
|eventCodeList||O||CADT||These values express a collection of keywords that may be relevant to the consumer of the documents in the registry. They may come from anywhere in the CDA document, according to its purpose.|
Code is valued)
|CADT||These are the display names for the collection of keywords described above.|
|formatCode||R||FM||The format code for each PCC Document content profile is provided within the document specifications.|
|healthcareFacilityTypeCode||R||CAD||A fixed value assigned to the Document Source and configured form a set of Affinity Domain defined values. Must be concistent with /clinicalDocument/code|
|R||CAD||Must be concistent with /clinicalDocument/code|
|intendedRecipient (for XDR, XDM)||O||SAT||
|legalAuthenticator||O||SAT||$person <= /ClinicalDocument/|
|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:
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:
$docID <= /ClinicalDocument/
|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:
|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.|
|sourcePatientId||R||SAT|| $patID <= /ClinicalDocument/recordTarget/|
|uniqueId||R||SAT||$docID <= /ClinicalDocument/id
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.
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.
XDS-SD leverages the XDS DocumentEntry Metadata requirements in the PCC-TF, volume 2, Section 220.127.116.11.1 and in PCC_TF-2/Bindings unless otherwise specified below
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 18.104.22.168.4.1.19322.214.171.124.
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 126.96.36.199.1 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.
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 188.8.131.52.2 or PCC_TF-2/Bindings.
No additional requirements. For more information, see PCC-TF-2 Section 184.108.40.206.3 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.
XD-Lab leverages the XDS DocumentEntry Metadata requirements in the PCC-TF, volume 2, Section 220.127.116.11.1 and in PCC_TF-2/Bindings unless otherwise specified below
XD-Lab documents further constrain the the XDSDocumentEntry.eventCodeList to the following.
|Attribute||Optional?||Source Type||Source/ Value|
|eventCodeList||R2||SAT||ClinicalDocument / component / structuredBody / component / section / entry / act / entryRelationship / organizer (templateId="18.104.22.168.4.1.19322.214.171.124.1")/ component / observation(templateId="126.96.36.199.4.1.193188.8.131.52.1.1")/code
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.
The XDSDocumentEntry.formatCode shall be urn:ihe:lab:xd-lab:2008 The formatCode codeSystem shall be 184.108.40.206.4.1.193220.127.116.11.
No additional constraints. For more information, see PCC-TF-2 Section 18.104.22.168.2 or PCC_TF-2/Bindings.
No additional requirements. For more information, see PCC-TF-2 Section 22.214.171.124.3 or PCC_TF-2/Bindings.

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="22.214.171.124.4.1.193126.96.36.199.1.1.3]"'> <!-- one or more assertions made by the content module --> </rule> </pattern> </schema>
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="188.8.131.52.4.1.193184.108.40.206.1.1.3]"'> <!-- 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="220.127.116.11.4.1.19318.104.22.168.1.1.2"]'> 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 = "22.214.171.124.4.1.193126.96.36.199.1.3.1"]'> Error: A referral summary must contain a reason for referral. </assert> <!-- Alert on any missing required if known elements --> <assert test='.//templateId[@root = "188.8.131.52.4.1.193184.108.40.206.1.3.8"]'> Warning: A referral summary should contain a list of history of past illnesses. </assert> <!-- Note any missing optional elements --> <assert test='.//templateId[@root = "220.127.116.11.4.1.19318.104.22.168.1.3.18"]'> Note: This referral summary does not contain the pertinent review of systems. </assert> </rule> </pattern> </schema>
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="22.214.171.124.4.1.193126.96.36.199.1.3.1"]'> <!-- 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="188.8.131.52.4.1.193184.108.40.206.1.3.1"]'> 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="220.127.116.11.4.1.19318.104.22.168.1.3.2"]'> <!-- The parent template will have already verified the type of object --> <!-- Verify that the parent templateId is also present. --> <assert test='templateId[@root="22.214.171.124.4.1.193126.96.36.199.1.3.1"]'> 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 = "188.8.131.52.4.1.193184.108.40.206.1.4.13"]'> 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"> <ns prefix="cda" uri="urn:hl7-org:v3" /> <phase id="errors"> <active pattern="ReasonForReferralUncoded_Errors"/> <active pattern="ReasonForReferralCoded_Errors"/> </phase> <phase id="manual"> <active pattern="ReasonForReferralUncoded_Manual"/> </phase> <pattern name='ReasonForReferralUncoded_Errors'> <rule context='*[templateId/@root="220.127.116.11.4.1.19318.104.22.168.1.3.1"]'> <assert test='section'> Error: The coded reason for referral module can only be used on a section. </assert> <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> </rule> </pattern> <pattern name='ReasonForReferralUncoded_Manual'> <rule context='*[templateId/@root="22.214.171.124.4.1.193126.96.36.199.1.3.1"]'> <assert test='false'> Manual: Manually verify that this section contains narrative providing the reason for referral. </assert> </pattern> <pattern name='ReasonForReferralCoded_Errors'> <rule context='*[templateId/@root="188.8.131.52.4.1.193184.108.40.206.1.3.2"]'> <assert test='templateId[@root="220.127.116.11.4.1.19318.104.22.168.1.3.1"]'> Error: The parent template identifier for the reason for referral not present. </assert> <assert test='.//templateId[@root = "22.214.171.124.4.1.193126.96.36.199.1.4.13"]'> Error: A coded reason for referral section must contain an simple observation. </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).
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.
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.
<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
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='188.8.131.52.184.108.40.20635.2' extension='EntityID'/> : . </playingEntity>
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.
<assignedEntity> <id extension='1' root='220.127.116.11.18.104.22.16835.1'/> <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='22.214.171.124.126.96.36.19935.2' 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.
