Public Comment


Emergency Department Encounter Summary (EDES)

Emergency Department Encounter Summary (EDES) is a summary of the patient’s current health status and a summary of care rendered in the ED between arrival and ED departure. The EDES is not (yet) intended to replace the ED Chart as a complete, legal document of care, but is intended as a collection of medical summaries with focused scope that can be used to fulfill a number of collaborative transfers of care. The Emergency Department Encounter Summary may include links to diagnostic tests performed during the ED encounter, as well as documentation of an initial Emergency Department Referral (a 2006 IHE work product), prehospital (EMS) records (IHE roadmap 2008), and the consultations of other providers.

Data released by the Centers for Disease Control and Prevention (CDC) estimates that there were over 110 million emergency department visits in 2004, making the emergency department (ED) chart (hereafter called Encounter Summary) one of the most common medical summaries in use today. Currently, the Emergency Department Encounter Summary remains largely a paper based artifact, and when produced by an Emergency Department information system (EDIS) is almost exclusively delivered as unstructured or loosely structured text.

The ED chart is used to communicate the details of an emergency department visit in a variety of ways. The chart is most frequently faxed or mailed to primary care providers, and is increasingly archived electronically to hospital clinical data repositories. The original (or a copy) must accompany the patient to the ward upon hospital admission where is can be reviewed by hospital providers, or a copy may be sent with the patient on transfer from ED to ED or from ED to other medical treatment facilities. Unfortunately, these frequently become lost or misplaced. Emergency Department Encounter Summaries have no standardized format, and may be frequently be difficult to read by users unfamiliar with their formatting. None yet carry any semantic meaning that could be consumed by a receiving EHR system (EHR-S).

The production and delivery of the Emergency Department Encounter Summary solves a number of problems, including:

  • Communication with and transfer of care back to the patient’s primary care physician.
  • Communication with care providers in the inpatient setting for patients admitted to the hospital from the emergency department.

The Emergency Department Encounter Summary could also be employed in:

  • Transfer of information to hospital and provider billing systems.
  • Transfer of information to regulatory and public health agencies requesting data from emergency department encounters.

Technical Approach

The Emergency Department Encounter Summary is a folder in XDS that defines a collection of documents. Several content profiles must be incuded to represent the various kinds of documents that might be found in the EDES Folder.

These content profiles include:

  • ED Triage Note – this documents contains data compiled during the ED triage process.
  • ED Nursing Note – this document contains data complied during the on-going care (after initial triage) of the ED patient.
  • Composite ED Triage and ED Nursing Note – this document can be used in lieu of individual triage and ED Nursing notes by implementers where both above documents may be consolidated into a single document.
  • ED Physician Note – this document is a summary view of ED physician documentation.
  • Prehospital Care Report – this document has been identified as a future work product and is on the PCC Roadmap for 2008.
  • EDR (Emergency Department Referral) – this document was developed in the 2006 IHE cycle to support referral of a patient to the emergency department.
  • Diagnostic Imaging Reports – shall be shared using XDS-I.
  • Lab Reports – Laboratory reports shall be shared using XD*-LAB.
  • Consultations – future document type specification.
  • Transfer Summary – future document type specification.
  • Summary of Death – future document type specification.

Authorship and Attestation

Each of the documents described above may have different authors. In some cases a single document can have multiple authors. Local policies may require certain documents to be attested to (signed) by the responsible provider, which may again be different from the author or authors. The content profiles allow for multiple authors to be recorded, and for the attestation (signature) to be provided according to the local policy.

Use Case - Emergency Department Visit

This use case presumes the patient is cared for at a hospital facility with an EDIS as well as a hospital information system. Additionally, the patient’s primary care provider is also assumed to posses an interoperable EHR system.

This use case begins upon the arrival of the patient to the emergency department. Data including mode of arrival, chief complaint, and other arrival data are manually entered into the EDIS. Additional data including past medical problems, medications and allergies, are obtained in one of the following ways:

  1. Entered manually into the EDIS by the triage nurse
  2. Imported from a legacy ED encounter within the EDIS
  3. Imported from the hospital information system or CDR, perhaps using [[PCC TF-1/QED|Query for Existing Data].
  4. Imported from an Emergency Department Referral (IHE 2006-2007).
  5. Imported using PHR Extract from portable media (IHE 2006-2007).
  6. Imported from a prehospital EMS report (Emergency Medical Services (EMS) to Emergency Dept Data Transfer, PCC Roadmap 2008-2009)

The patient undergoes assessments by a triage nurse, is assigned a triage category (i.e. emergent, urgent, non-urgent). The patient is then registered and demographic data is obtained. One taken to the treatment area, the patient undergoes additional assessments by a primary RN, and seen by an ED physician who performs a history and physical, orders various diagnostic tests, determines a course of therapy, orders medications to be administered in the ED and performs procedures on the patient. Upon completion of ED care, the patient is either admitted to the hospital, discharged from the ED, or transferred to another facility. Hence, the use case can take one of three branches:

  1. If admitted, the EDES is sent to the hospital information system where it can be viewed by providers, or read by the EHR system so that medical summary data and details of care rendered in the ED available to inpatient providers.
  2. If the patient is discharged the EDES is sent to the patients primary care physician as a summary of care rendered during the ED encounter.
  3. If the patient is transferred to another facility, the EDES is posted to the RHIO and made available for providers at the receiving facility.

Example

Mr. John Smith, a longstanding patient of Dr. Mark Klein, is 62 year old man with hypertension and diabetes who awoke with acute onset of fever, right-sided chest pain and cough. He presents to the IHE ED via EMS where he is triaged by nurse Karen Ross who collects his past medical history, medications, allergies, mode of arrival, and inputs this data into the EDIS. Mr. Smith is taken directly to the treatment area where he is assigned to nurse Barbara Reiter who obtains vital signs, baseline pulse oximetry, places the patient on oxygen, and obtains IV access. She documents her assessments and interventions in the EDIS. The patient is seen by Dr. William Reed who performs and records a history and physical examination, orders an ECG, chest radiograph, CBC, electrolytes, and blood cultures. The chest radiograph reveals bi-lobar pneumonia and the ECG is slightly abnormal. Ceftriaxone 1gm IV plus Azythromycin 500mg PO are administered. After multiple attempts by Dr. Reed to contact Dr. Klein, Mr. Smith is admitted to a intermediate care bed under the care of Dr. Herman Edwards the IHE hospitalist. Upon hospital admission, Dr. Reed completes the record and, as the responsible attending physician, electronically signs the ED chart authenticating the EDES. In this institution, the initial ED attending physician to see the patient is the legal authenticator for all documents, and may only delegate this responsibility to another provider through a formal transfer of care. The EDES is posted to the RHIO and also sent to the hospital information system. Using the HIS, the nurse on the intermediate care ward accesses the record and notes the time and administration of antibiotics. When Dr. Klein reaches the office in the morning, his office EHR-S notifies him that his patient was seen in the IHE ED the previous night, and displays the ED Encounter Summary.

Actors/Transaction

There are two actors in the EDES 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.

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.


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.

EDES Content Modules

Triage Note

The triage note is a CDA document that may be submitted to an ED Folder in order to record the act of triaging a patient upon presentation to the emergency department. The triage note is designed to support a comprehensive triage assessment, although it is recognized that providers may not capture the entire list of sections, owing to patient presentation, acuity or time constraints.

Nursing Note

The nursing note is a CDA document that may be submitted to an ED Folder in order to record the act of nursing care delivered to a patient in the emergency department. The ED nursing note is designed to support documentation sufficient to support transfer of care. It is recognized that the ED Nursing Note specification is not sufficient to document all medicolegal facets of care, and conversely that providers may not capture the entire list of sections, owing to patient presentation, acuity or time constraints.

Composite Triage and Nursing Note

The composite triage and nursing note is a CDA document that may be submitted to an ED Folder in order to record the act of both triage and nursing care delivered to a patient in the emergency department. The ED nursing note is designed to support documentation sufficient to support transfer of care. It is recognized that the specification is not sufficient to document all medicolegal facets of care, and conversely that providers may not capture the entire list of sections, owing to patient presentation, acuity or time constraints.

ED Physician Note

The ED Physician Note is a CDA document that may be submitted to an ED Folder in order to record the care delivered to a patient in the emergency department. The ED physician note is designed to support documentation sufficient to support transfer of care. It is recognized that the specification is not sufficient to document all medicolegal facets of care, and conversely that providers may not capture the entire list of sections, owing to patient presentation, acuity or time constraints.

Grouping

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.

Content Binding Actor Optionality
Triage Note Medical Document Binding to XDS, XDM and XDR Content Creator R
Content Consumer R
Nursing Note Medical Document Binding to XDS, XDM and XDR Content Creator R
Content Consumer R
Composite Triage and Nursing Note Medical Document Binding to XDS, XDM and XDR Content Creator R
Content Consumer R
ED Physician Note Medical Document Binding to XDS, XDM and XDR Content Creator R
Content Consumer R

Notification of Document Availability (NAV)

A Document Source should provide the capability to issue a Send Notification Transaction per the ITI Notification of Document Availability (NAV) Integration Profile in order to notify one or more Document Consumer(s) of the availability of one or more documents for retrieval. One of the Acknowledgement Request options may be used to request from a Document Consumer that an acknowledgement should be returned when it has received and processed the notification. A Document Consumer should provide the capability to receive a Receive Notification Transaction per the NAV Integration Profile in order to be notified by Document Sources of the availability of one or more documents for retrieval. The Send Acknowledgement option may be used to issue a Send Acknowledgement to a Document Source that the notification was received and processed.

Document Digital Signature (DSG)

When a Content Creator Actor needs to digitally sign a document in a submission set, it may support the Digital Signature (DSG) Content Profile as a Document Source. When a Content Consumer Actor needs to verify a Digital Signature, it may retrieve the digital signature document and may perform the verification against the signed document content.

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

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.

IHE Integration Statement Date 12 Oct 2005
Vendor Product Name Version
Any Medical Systems Co. IntegrateRecord V2.3

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.

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.

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.

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">
  <ns prefix="cda" uri="urn:hl7-org:v3" />

      <assert test='section'>
        Error: The coded reason for referral module can only be used on a section.
      </assert>
      <assert test='code[@code = "42349-1"]'>

      <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 name='ReasonForReferralUncoded_Manual'>
    <rule context='*[templateId/@root="1.3.6.1.4.1.19376.1.5.3.1.3.1"]'>
      <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="1.3.6.1.4.1.19376.1.5.3.1.3.2"]'>
      <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 not present.
      </assert>
      <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>
    </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.
