Introduction

This is a draft of the Antepartum Record Profile (APR) supplement to the PCC Technical Framework. This draft is a work in progress, not the official supplement or profile.

Profile Abstract

The Antepartum Record Profile (APR) is based on data elements from prenatal records currently in common use, and includes the following documents:

  1. Antepartum History & Physical – The initial assessment and physical
  2. Antepartum Summary – Summary of the most critical information
  3. Antepartum Laboratory – Laboratory Evaluations
  4. Antepartum Education – Education Record

Additional commonly used forms not included in this profile are:

  1. A patient generated obstetric medical history
  2. A postpartum form

A sample form showing the data elements may be found at: http://www.acog.org/acb-custom/aa128.pdf

This profile defines the implementation of HL7 CDA documents to represent these data elements along with the XDS, XDR and XDM bindings. This profile also defines mechanisms to group them into a single logical folder.

Glossary

The following elements are found in the Antepartum History & Physical document of the Antepartum Record:

Abortion, Induced (AB, Induced)
Number of induced abortions by patient. An induced abortion is a deliberate termination of pregnancy.
Abortion Spontaneous (AB, Spontaneous)
Number of spontaneous abortions by patient. A spontaneous abortion is a natural loss of the products of conception.

Open Issues

  1. How does the XDS Folder structure need to be handled?
  2. Several LOINC and SNOMED codes are in the process of being created. These codes are denoted by a preceeding "xx-" or "XX-" with an abbreviated description of the code following.

Closed Issues

  1. For Antepartum Laboratory there is a LOINC code for Laboratory Studies (26436-6) - is this too general? Should a new code be requested specific to Antepartum labs? The concern is that this could cause mapping issues in an EMR that has other lab results that are considered to be specific to antepartum that would live under that same loinc section code. the IHE formatCode supplied in the XDS Metadata will identify this as an Antepartum Laboratory document so a LOINC code is not needed.

Add the following bullet to the list of profiles
  • Antepartum Record - A folder of content profiles that contains the record of antepartum care including initial patient history and physical, recurring evaluations of mother and fetus(es), laboratory studies, patient education, and on-going plans of care.

Antepartum Record (APR)

The Antepartum Record Profile (APR) is based on the data elements from prenatal records currently in common use.

Obstetric patients in labor and admitted to the hospital or birthing facility optimally would have a complete summary of their antepartum ambulatory care available at the time of admission to evaluate and / or ameliorate risk. This same data is required at any visit to the birthing facility or hospital for any other problems or special care needs of the patient. The antepartum record optimally would be available in its entirety for appropriate continuity of care and legal concerns.

The aggregated record provides important information for all health care professionals who are part of the patient's obstetric care team. Patients may incorporate the data from this aggregated record into their personal health record. Administration staff may use data for billing and payment purposes.

A typical pregnancy duration is approximately 40 weeks. Patient care during that time includes an initial history and physical examination, followed by repetitive office visits with multiple laboratory studies, imaging/ ultrasound studies, and serial physical examinations. As the patient is seen over a finite period for care, aggregation of data relevant to the evaluation of the obstetric patient upon presentation to the birthing facility or hospital is commonly collected on paper forms. This antepartum record contains the most critical information needed to provide care for the patient during pregnancy, delivery and the post-partum period. This data must all be presented and evaluated upon entry to the birthing facility or hospital to ensure optimal continuity of care for the patient and the fetus.

Although the patient and her care provider may plan for a vaginal method of delivery, there is a substantive chance the delivery route may be surgical, requiring anesthesia and post-surgical care.

Current practice is to copy the patient's paper chart at various times during the pregnancy (as at 28 weeks and at 36 weeks of completed gestation), and transport the copies of the chart to the hospital the patient intends to use for delivery. Should the patient arrive at the birthing facility or hospital prior to the chart copy arriving, or if the chart (or information within the chart) is missing on presentation of the patient (a frequent occurrence), the care team must repeat laboratory or imaging studies. This results in unwarranted and duplicative tests, is wasteful of time and resources, and leads to dissatisfied patients. Further, missing or incomplete information about the patient’s clinical status may create a situation where critical information is unavailable which may ultimately result in an injury, inadequate aftercare, or other undesirable outcomes.

A large portion of patients arrive at the birthing facility or hospital without complete documentation. In one recent U.S. study, approximately 70 % of patients (with paper charts) arrived at the birthing facility without their current medical record being available. While only one hospital was involved in this study, one can see the extent of the issue, with pregnant patients possibly going to a different hospital than planned (preterm labor, rapid labor and unable to make it to the planned delivery hospital, or visiting a distant city), moving mid-care, or with a covering physician (rather than the primary obstetrician) on call.

In a Swedish study done in the 1990’s, critical data on paper records were incomplete from 45 to 87.5% of the time. Thus, availability of current medical records remains a significant problem for most hospital birthing facilities; availability of key information electronically will significantly enhance patient safety.

Use Cases

Use Case 1: Basic Antepartum Record Use Case

This use case reflects the course of care during an uncomplicated pregnancy.

Pre-condition
The patient’s obstetrician sees the patient for her initial and subsequent prenatal visits. During the initial and/or subsequent prenatal visits information is collected and may be updated within the office Electronic Health Record (EHR), these include:

  • Patient demographics
  • Menstrual history
  • Obstetric history
  • Medical history including surgical history, psych-social history
  • Genetic history and screening/Teratology counseling
  • Infection history
  • Family history
  • Initial and subsequent physical examination
  • Medications
  • Problems and risk factors for preterm birth
  • Allergies
  • Prenatal visit information
  • Prenatal Laboratory results
  • Documentation of patient education and counseling
  • Plans for care

The information collected during the patient’s prenatal visits make up the components which are included in the patient’s Antepartum Record.

Event(s)
Scenario 1 - At a specified time an initial and/or subsequent patient Antepartum Record is transmitted by the patient’s prenatal care provider EHR to the intended facility for delivery.

The intended facility of delivery health information system receives the transmitted initial and/or subsequent patient Antepartum Record.

Scenario 2 - At a specified time the initial and/or subsequent patient Antepartum Record registry information is transmitted by the patient’s obstetrician EHR to a registry.

The facility of delivery health information system queries the registry repository for the applicable patient’s Antepartum Record(s). A request is made for the patient’s Antepartum Record. The applicable system which contains the patient’s Antepartum Record then makes available the patients Antepartum Record information to the requesting facility of delivery.

Post-condition
The received patient Antepartum Record can be viewed and/or imported into the facility for delivery health information system to facilitate patient care by healthcare professional at the time of delivery for the mother and newborn.

Use Case 2: Antepartum Consultative Care

This use case reflects an example of perinatologist consultative prenatal care.

Pre-condition
The patient’s prenatal care provider sees the patient for her pregnancy in the ambulatory (office) setting. During the pregnancy, the patient is noted to have a medical problem requiring consultation with a maternal-fetal medicine specialist (perinatologist). The office obtains pre-authorization from the insurance payer for the consult and for the intended or anticipated route of delivery. Preauthorization information is transmitted to both the consultant and to the hospital.

Events
The patient is seen in the prenatal care provider’s office where a complete health history (e.g. medical and surgical history, psycho-social history) is obtained and recorded in the office EHR and sent to the consultive care provider office EHR. Data from the perinatologist’s consultation report is incorporated as appropriate. Laboratory and imaging reports ordered by the perinatologist consultant as well as the perinatologist’s consultation report are displayed electronically to the prenatal care provider. The prenatal care provider reviews the consultation report from the perinatologist’s office and imaging studies ordered by the perinatologist along with current recorded data. Physical exam reveals some abnormalities. The prenatal care provider orders additional laboratory studies, and sends the patient to the hospital or birthing facility.

When the laboratory results return, the prenatal care provider completes the admission history and physical, allergies, medications, includes the data prepared or ordered by the perinatologist, and makes it available to the hospital or birthing facility. This data includes an assessment of the patient’s health status, and the requisite data summarized from the antepartum care given. The care team assures the complete collection of documents needed is available and that there is a suitable environment with appropriate support for post-delivery after-care.

Post-condition
The pre-delivery history and physical and Antepartum Summary with appropriate relationships to the perinatologist consultation, and all the antepartum laboratory and imaging studies are available to the obstetrician and the hospital or birthing center personnel for incorporation into their respective EHRs. The history and physical is also available to the patient for viewing and incorporation into the patient’s PHR, and into the newborn baby’s PHR.

Use Case 3: Antepartum Collaborative Care

This use case reflects two-way transmission of data in an example of collaborative care.

Pre-condition
A pregnant diabetic patient is seen by her prenatal care provider in the office for prenatal care. An ultrasound is performed to determine gestational age. The patient is sent to a consultant (e.g. perinatologist) as a high-risk patient. Her prenatal care provider transmits preauthorization insurance information, labs and anticipated route of delivery to the consultant and/or hospital birthing facility.

Events
The patient returns to her consultant biweekly for blood testing and ultrasounds (when necessary) in addition to regular ob visits. The consultant reports back to the obstetrician after each visit. Complete history and physical, imaging and additional labs are performed during patient’s regular visit with her prenatal care provider.

The patient arrives at birthing facility. Prenatal care provider completes the admission history and physical, allergies, medications, and includes the data prepared or ordered by the consultant, and makes it available to the hospital birthing facility. This data includes an assessment of the patient’s health status, and the requisite data summarized from the antepartum care given. The care team documents that the complete collection of documents required is available.

Post-condition
The patient’s prenatal care provider delivers by cesarean section after anesthesia. The post-partum discharge planning is notified and assures that there is a suitable environment with appropriate support for post-delivery after-care. Delivery information, i.e. birth weight, APGAR scores, type of delivery, etc is available for pediatrician. The patient's postpartum record is sent to the consultant for incorporation into the patient's record. The patient can incorporate the history and physical into her own personal health record and the newborn’s records into the newborn's personal health record.

Actors/Transaction

There are two actors in this 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 by section 3.7 Content Bindings with XDS, XDM and XDR found in the Patient Care Coordination Technical Framework

Grouping

Content Bindings with XDS, XDM and XDR

It is expected that the transfers of care will occur in an environment where the physician offices and hospitals have a coordinated infrastructure that serves the information sharing needs of this community of care. Several mechanisms are supported by IHE profiles:

For more details on these profiles, see the IHE IT Infrastructure Technical Framework.

Content profiles may impose additional requirements on the transactions used when grouped with actors from other IHE 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 must be grouped with appropriate actors from the XDS, XDM or XDR profiles, and the metadata sent in the document sharing or interchange messages has specific relationships to the content of the clinical document described in the content profile.

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.

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. The Antepartum Record Profile currently consists of four document content modules, with potentially more added in future work. One or more of these document content modules are required for the implementation of APR. For example, a system may choose to implement the Antepartum Summary the first year, and implement the additional content modules of Antepartum History & Physical, Antepartum Laboratory and Antepartum Education is following years.

This diagram specifically excludes other infrastructure interactions for simplicity and readability. These infrastructure interactions may be found elsewhere in the framework.

Data from the patient's prenatal care aggregates into her electronic antepartum record by the obstetric provider. The antepartum record is then sent to a consultant who updates the antepartum record, and returns it to the obstetric provider. The electronic antepartum record is then sent to the birthing facility at the appropriate time(s). The consultant may also send the antepartum record directly to the hospital.


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 Connectathon, 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 Connectathon 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 template

An IHE Integration Statement template (MS Word version) is available here.

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.

PCC Content Modules

This chapter contains the various content modules and value sets that are used with IHE Patient Care Coordintation profiles and transactions.

Conventions

Various tables used in this section will further constrain the content. Within this volume, the follow conventions are used.

R
A "Required" data element is one that shall always be provided. If there is information available, the data element must be present. If there is no information available, or it cannot be transmitted, the data element must contain a value indicating the reason for omission of the data. (See PCC TF-2: 5.3.4.2 for a list of appropriate statements).
R2
A "Required if data present" data element is one that shall be provided when a value exists. If the information cannot be transmitted, the data element shall contain a value indicating the reason for omission of the data. If no such information is available to the creator or if such information is not available in a well identified manner (e.g. buried in a free form narrative that contains additional information relevant to other sections) or if the creator requires that information be absent, the R2 section shall be entirely absent. (See section PCC TF-2: 5.3.4.2 for a list of appropriate statements).
O
An optional data element is one that may be provided, irrespective of whether the information is available or not. If the implementation elects to support this optional section, then its support shall meet the requirement set forth for the "Required if data present" or R2.
C
A conditional data element is one that is required, required if known or optional depending upon other conditions. These will have further notes explaining when the data element is required, et cetera.


Note: The definitions of R, R2, and O differ slightly from other IHE profiles. This is due in part to the fact that local regulations and policies may in fact prohibit the transmission of certain information, and that a human decision to transmit the information may be required in many cases.


Folder Content Modules

This section contains modules that describe the content requirements of Folders used with XDS, XDM or XDR. When workflows are completed normally, the folders will contain documents with the optionality specified in the tables shown below. Under certain circumstances, the folders will not meet the optionality requirements described below, for example, when the patient leaves before treatment is completed.

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"]'>
        Error: The section type code of the reason for referral section must be 42349-1

      </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'>

      <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"]'>

        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=' '/>
 
 <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'/>
 
 <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.
