This Content profile describes an anatomic pathology structured report (APSR) as a CDA r2 document to be published towards a document sharing resource such as a shared electronic health record used by a community of care providers, relying on one of the infrastructure document sharing/exchanging profiles defined in IHE ITI TF.
 
 
Anatomicpathology reports (APR) document the pathologic findings in specimens removed from patients for diagnostic or therapeutic reasons. This information can be used for patient care, clinical research and epidemiology. Standardizing andcomputerizing APRs is necessary to improve the quality of reporting and the exchange of APR Information.
 
 
This Content profile describes an anatomic pathology structured report (APSR) as a CDA r2 document to be published towards a document sharing resource such as a shared electronic health record used by a community of care providers, relying on one of the infrastructure document sharing/exchanging profiles defined in IHE ITI TF.
 
 
Anatomic pathology reports (APR) document the pathologic findings in specimens removed from patients for diagnostic or therapeutic reasons. This information can be used for patient care, clinical research and epidemiology. Standardizing and computerizing APRs is necessary to improve the quality of reporting and the exchange of APR information.
 
 
The current scope of this IHE content profile covers APSR for surgical pathology in all fields of anatomic pathology (cancers, benign neoplasms as well as non-neoplastic conditions) as well as for Cytopathology. The profile handles information of “traditional” pathology observation using light microscopy (including immunohistochemistry, FISH, etc.).
 
 
Forensic pathology (autopsy, toxicology) will be addressed in further cycles as well as Special ancillary techniques (e.g., flow cytometry, cytogenetics, electron microscopy).
 
 
Goldsmith provides recent recommendations that delineate the required, preferred, and optional elements which should be included in any APR for surgical pathology, regardless of report types.
 
 
Several international initiatives intend to define standard structured templates for
 
specific types of APRs. In the cancer domain, in the United States, the CAP (College of American Pathologists) has published 80 cancer APSR templates (cancer checklists and background information)[http://www.cap.org]. In France, the SFP (French society of pathology) [http://www.sfpathol.org] and the INCa (French National Cancer Institute) [http://www.e-cancer.fr] have published 23 APSR templates of minimal set of data required for a primary tumor. In Australasia, the Royal College of Pathologists Australasia (RCPA) and the Cancer Australia developed an initial 6 reporting protocols (lung, melanoma, breast, colorectal, lymphoma and prostate) and a framework to guide development of the protocols, in partnership with national clinician and pathologist organizations. In some countries, the recommendations for generic and specific APSR requirements have become clinical guidelines, the use of which may be required by accrediting bodies.
 
 
This profile has also benefited from the guidance on cancer AP reports provided by the North-American Association of Central Cancer Registries; some of the example snippets captured in the profile leverage the NAACCR Standards for Cancer Registries, Volume V, Pathology Laboratory Electronic Reporting.
 
 
In addition to standardizing the cancer APR contents, it is necessary to computerize them. Several studies have focused on defining an appropriate IT standard comprising the structured and encoded clinical documents. Some of the implementation guides of APSRs proposed within these initiatives are not based on international healthcare IT standards (e.g., CAP eCC), other are based on either HL7 CDA r2 or CEN archetypes. HL7 CDA r2 is one of the most reliable standards that can support these needs. CDA allows the clinical data to be both machine and human-readable and provides a framework for incremental growth in the granularity of structured, codes-bound clinical information. This document takes into consideration current very few national CDA implementation guides
 
for the APSR developed in Netherlands (National IT Institute for Healthcare in the Netherlands [www.nictiz.nl] and in Germany.
 
 
This Content profile describes an anatomic pathology report shared in a human-readable format, which may include images. In addition, this electronic AP report SHALL contain anatomic pathology observations in a machine-readable format, to facilitate the integration of these observations in the database of a consumer system.
 
 
The Definition of required, preferred and optional elements in this content profile is mainly based on Goldsmith, for generic surgical pathology APSR (regardless of report
 
types) and, in the cancer domain, on standard structured templates provided by United States, the CAP (College of American Pathologists) [http://www.cap.org.], the SFP (French society of pathology) [http://www.sfpathol.org] and INCa (French National Cancer Institute) [http://www.e-cancer.fr] and the Royal College of Pathologists Australasia (RCPA).
 
 
Structured reports are composed of a header, which provides the context of care (patient, care providers, pathologists, laboratories, order, act documented …), and a body. The latter provides the clinical information, which accompanied the order and specimens as well as the observations, findings and conclusions delivered by the pathologist after
 
examination. 
 
 
The anatomic pathology report described in this profile, with its set of anatomic pathology observations in a machine-readable format, MAY also be used to share
 
historical results with appropriate content anonymization and Patient identification pseudonymization to create shared distributed repositories of anatomic pathology information.
 
 
Both the header and the body provide human-readable information. The body is a hierarchy of sections. Each section presents its
 
content in its ''text'' element, as human-readable text, possibly illustrated by some embedded images. This human-readable content, or a part of it, may also be present as machine-readable data coded with the appropriate terminologies (e.g., ICD-O-3, SNOMED CT, LOINC, ADICAP, etc.) in entry elements at the bottom of the section.
 
 
There are zero or more ''entry'' elements in a section. Each ''entry'' element carries the machine-readable data related to a single specimen or to a group of specimens observed together. The entry is then subdivided per problem investigated.
 
 
The ''text'' element of the section is supposed to reflect the same organization: per specimen, and then, per problem investigated on the specimen. The profile leaves the layout of the text element up to the Content Creator applications, or to further constraints brought by national extensions. However, given that the ''text'' element is usually composed of free text (e.g., dictated text), assembled with the text generated from the set of data, machine-encoded in the entry elements below, the Content Creator application MUST handle these two kinds of content, and provide a user interface, which precludes any confusion between them, both at creation time and update time (e.g., using forms with dedicated free text areas and distinct protected areas for coded fields).
 
 
== 4.1 APSR Actors/Transactions ==
 
 
This section references two other IHE Technical Frameworks:
 
 
*IT Infrastructure Technical Framework (ITI TF)
 
*Patient Care Coordination Technical Framework (PCC TF)
 
 
There
 
are two actors in this profile, the Content Creator and the Content
 
Consumer. 
 
 
'''Content Creator''':      A
 
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
 
 
Content
 
(i.e., an anatomic pathology structured report) 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 anatomic pathology structured reports from one actor to the other is addressed by the use of appropriate content bindings with XDS, XDM or XDR integration profiles as explained in section 4 of Volume 3 of the Anatomic Pathology Technical Framework.

== 4.3 APSR Actor Groupings and Profile Interactions ==
 
 
It is expected that the sharing of anatomic pathology structured reports 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:
 
*A registry/repository-based infrastructure is defined by the IHE Cross-Enterprise Document Sharing (XDS) and other IHE Integration Profiles such as patient identification (PIX & PDQ), and notification of availability of documents (NAV).
 
*A media-based infrastructure is defined by the IHE Cross-Enterprise Document Media Interchange (XDM) profile.
 
*A reliable messaging-based infrastructure is defined by the IHE Cross-Enterprise Document Reliable Interchange (XDR) profile.
 
*All of these infrastructures support Security and privacy through the use of the Consistent Time (CT) and Audit Trail and Node Authentication (ATNA) profiles.
 
 
For more details on these profiles, see the IHE IT Infrastructure Technical Framework
 
 
Such an infrastructure is assumed by the use cases described in this Profile.
 
 
A content binding describes how the payloads used in IHE transactions are related to and/or constrained by the data elements contained within the content sent or received in those transactions.  The APSR Content Profile applies one binding, which is used when grouping the Content Creator with the IHE ITI XDS, XDM or XDR Integration Profiles.
 
 
The content and the binding are described in Volume 3 of the IHE Anatomic Pathology Technical Framework.
 
 
 
 
== 4.4 APSR Process Flow ==
 
 
 
 
=== 4.4.1 Use Cases ===
 
 
==== 4.4.1.1 Use case 1: General case ====
 
 
 
Barbara Breast visits Sammy Surgeon for removal of a breast tumor. Sammy Surgeon orders the Requested Procedure “Breast surgical specimen - pathological examination” and sends the specimen(s) to the anatomic pathology department.
 
 
Specimen(s) is (are) accessioned by the anatomic pathology department. The staff performs a macroscopic examination of the specimen(s); gross imaging is performed if needed. The specimen(s) are processed for microscopic examination and other special ancillary techniques or tissue banking if needed. During the imaging interpretation process, microscopic imaging is performed if needed. At the end of the interpretation process, pathologist queries the Content Creator application for the appropriate APSR template, fills the form, binds some relevant images and/or regions of interest to specific observation(s), validates and signs the document.
 
 
==== 4.4.1.2 Use case 2: Specimen collector is not the ordering physician ====
 
 
Patricia Pathologist collects bone marrow from Peter Patient in the clinical ward.
 
 
Specimen(s) is (are) accessioned by the anatomic pathology
 
department. The staff performs a macroscopic examination of the specimen(s);
 
gross imaging is performed if needed. The specimen(s) are processed for
 
microscopic examination and other special ancillary techniques or tissue
 
banking if needed. During the imaging interpretation process, microscopic
 
imaging is performed if needed. At the end of the interpretation process,
 
pathologist queries the '''Content Creator''' for
 
the appropriate APSR template, fills the form, binds some relevant images
 
and/or regions of interest to specific observation(s), validates and signs the
 
document.
 
 
==== 4.4.1.3 Use case 3: Multi-step reporting ====
 
 
Barbara Breast
 
visits Sammy Surgeon for removal of a breast tumor. Sammy Surgeon orders the
 
Requested Procedure “Breast surgical specimen - Frozen sections &
 
pathological examination” and sends the specimen(s) to the anatomic pathology
 
department.
 
 
Specimen(s) is (are) accessioned by the anatomic pathology
 
department. The staff performs a macroscopic examination of the specimen(s),
 
gross imaging is performed if needed. The specimen(s) are processed for
 
intraoperative observation if needed, and tissue banking if needed (e.g., for
 
research purpose). During the imaging interpretation process of frozen
 
sections, microscopic imaging is performed if needed. At the end of the
 
interpretation process, pathologist queries the '''Content Creator''' for the appropriate APSR template, fills the
 
intraoperative observation section, binds some relevant images and/or regions
 
of interest to specific observation(s) if needed, validates and signs (i.e.,
 
legally authenticates) the preliminary APSR.
 
 
The day after, the specimen(s) are processed for microscopic
 
examination and other special ancillary techniques if needed. During the
 
imaging interpretation process, microscopic imaging is performed if needed. At
 
the end of the interpretation process, pathologist queries the '''Content Creator''' for the preliminary
 
APSR, fills the form, binds some relevant images and/or regions of interest to
 
specific observation(s), validates and signs (i.e., legally authenticates) the final
 
APSR.
 
 
==== 4.4.1.4 Use case 4: Opinion request ====
 
 
There are various
 
situations in which an opinion request is issued: External expert consultation
 
(requested by Philip Pathologist, often before a final report is issued).
 
Second opinion request (usually made by a treating physician or patient/family,
 
or lawyer/court in malpractice cases). External slide review (usually routine
 
review of slides required by protocols in an outside treating institution).
 
These may vary in terms or workflow and even the materials accessed by the
 
outside lab.
 
 
''Requiring pathologist''
 
Philip Pathologist
 
asks for second opinion for the case of Peter Patient diagnosed as lymphoma. He
 
sends block(s) or slide(s) or shares/sends whole slide images to Patricia
 
pathologist, requesting her expertise on this material. He uses the '''Content Creator application''' to derive
 
the anatomic pathology opinion request document from the preliminary APSR of
 
Peter Patient.
 
 
Philip Pathologist
 
later on uses his Content Consumer application
 
to view and import the APSR from Patricia Pathologist. He uses this report to
 
finalize and issue his own APSR in his application acting as a Content Creator.
 
 
''Requested pathologist''
 
 
Patricia
 
Pathologist accepts to deliver second opinion about the case of Peter Patient
 
diagnosed as lymphoma.
 
 
''Block(s)''
 
 
The specimen(s) are processed for microscopic examination and other
 
special ancillary techniques if needed. During the imaging interpretation
 
process, microscopic imaging is performed if needed. At the end of the
 
interpretation process, Patricia Pathologist queries the Content Creator for the appropriate APSR template, fills the form,
 
binds some relevant images and/or regions of interest to specific
 
observation(s), validates and signs the document.
 
 
''Slide(s)''
 
 
During the imaging interpretation process, microscopic imaging is
 
performed if needed. At the end of the interpretation process, Patricia
 
Pathologist queries the Content Creator for
 
the appropriate APSR template, fills the form, binds some relevant images
 
and/or regions of interest to specific observation(s), validates and signs the
 
document.
 
 
''Whole slide image(s)''
 
 
At the end of the interpretation process, Patricia Pathologist
 
queries the '''Content Creator''' for the
 
appropriate APSR template, fills the form, binds some relevant images and/or
 
regions of interest to specific observation(s), validates and signs the
 
document.
 
 
 
== 4.5 APSR Security considerations ==
 
 
=== 4.5.1Integrity ===
 
 
The choice on whether
 
the digital signature is performed at the transaction level (XDS, XDM, XDR) or
 
at the content level is left up to national extensions. If the report is
 
digitally signed, the person having signed it SHALL be the person represented
 
in the ''legalAuthenticator'' element of
 
the CDA header.
 
 
 
=== 4.5.2 Confidentiality ===
 
 
In the
 
context of patient care coordination the anatomic pathology report described in
 
this profile contains patient personal data, and as such must be handled in
 
conformance to the local privacy policies.
 
 
In other
 
contexts such as public health, surveillance, research, appropriate content
 
anonymization and patient identification pseudonymization may be required by
 
local policies.

== 1.2 Overview of Volume 3 ==
 
 
 
The IHE Technical
 
Framework is based on actors that interact through transactions using some form
 
of content.
 
 
 
Actors are
 
information systems or components of information systems that produce, manage,
 
or act on information associated with operational activities in the enterprise.
 
 
 
Transactions are
 
interactions between actors that transfer the required information through
 
standards-based messages.
 
 
 
Content profiles
 
specify how the payload of a transaction fits into a specific use of that
 
transaction. A content profile has three main parts. The first part describes
 
the use case. The second part is binding to a specific IHE transaction, which
 
describes how the content affects the transaction. The third part is a Content
 
Module, which describes the payload of the transaction. A content module is
 
specified so as to be independent of the transaction in which it appears. This
 
overall content module is itself an assemblage of smaller content modules,
 
which in turn may assemble smaller content modules, conforming to the chosen
 
standard.
 
 
 
In particular,
 
the Anatomic Pathology Technical Framework provides a set of content profiles
 
for the sharing of persistent clinical document produced by the anatomic
 
pathology domain.
 
 
 
This Volume 3
 
specifies the content modules produced at various granularity levels (from a
 
whole clinical document to a tiny reusable piece of coded data) by the Anatomic
 
Pathology domain of IHE for its own content profiles.
 
 
 
Some of these
 
content modules produced here, may be used by content modules of higher
 
granularity from other domains (e.g., Patient Care Coordination).
 
 
 
Some of these
 
content modules produced here, may leverage content modules of lower
 
granularity from other domains (e.g., PCC, RAD, etc.).

== 1.9 Glossary ==
 
 
The glossary of
 
the Anatomic Pathology Technical Framework is centralized in PAT TF-1:1.12.
 
 
= 2 Content Modules – Basic Principles =
 
 
This Volume 3 of
 
the PAT TF organizes content modules categorically by the base standard. At
 
present, PAT TF-3 uses only one base standard, CDA Release 2.0, but this is
 
expected to change over time. Underneath each standard, the content modules are
 
organized using a very coarse hierarchy inherent to the standard.
 
 
Each content
 
module can be viewed as the definition of a "class" in software
 
design terms, and has associated with it a name. Like "class"
 
definitions in software design, a content module is a "contract", and
 
the PAT TF-3 defines that contract in terms of constraints that must be obeyed
 
by instances of that content module. Each content module has a name, also known
 
as its template identifier. The template identifiers are used to identify the
 
contract agreed to by the content module. The Anatomic Pathology Technical
 
Committee is responsible for assigning the template identifiers to each content
 
module.
 
 
Like classes,
 
content modules may inherit features of other content modules of the same type
 
(e.g., Document, Section or Entry) by defining the parent content module that
 
they inherit from. They may not inherit features from a different type.
 
 
Constraints that
 
apply to any content module will always apply to any content modules that
 
inherit from it. Thus, the "contracts" are always valid down the
 
inheritance hierarchy.
 
 
The PAT TF-3 uses
 
the convention that a content module cannot have more than one parent (although
 
it may have several ancestors). This convention is not due to any specific
 
technical limitation of the technical framework, but does make it easier for
 
software developers to implement content modules.
 
 
Each content
 
module has a list of data elements that are required (R), required if known
 
(R2), conditional (C) or optional (O).
 
 
Other data
 
elements may be included in an instance of a content module over what is
 
defined by the PAT TF-3. Content consumers are not required to process these
 
elements, and if they do not understand them, must ignore them. Thus, it is not
 
an error to include more than is asked for, but it is an error to reject a
 
content module because it contains more than is defined by the framework. This
 
allows value to be added to the content modules delivered internationally in
 
this framework, through national extensions built by the national IHE
 
organizations in various countries. It further allows content modules to be
 
defined later by IHE that are refinements or improvements over previous content
 
modules.
 
 
 
= 3 IHE Transactions =
 
 
This section
 
defines each IHE transaction in detail, specifying the standards used, and the
 
information transferred.
 
 
 
== 3.1 Cross Enterprise Document Content Transactions ==
 
 
 
At present, all
 
transactions used by the Anatomic Pathology Content Profiles appear in ITI TF-2a
 
and ITI TF-2b.
 
 
General Options
 
defined in content profiles for a Content Consumer are listed below.
 
 
=== 3.1.1 View Option ===
 
 
A Content
 
Consumer that supports the View Option shall be able to:
 
 
1. Use the appropriate XD* transactions to obtain the document along with associated
 
necessary metadata.
 
 
2. Render the document for viewing. This rendering shall meet the requirements defined
 
for CDA Release 2 content presentation semantics (See Section 1.2.4 of the CDA
 
Specification: Human readability and rendering CDA Documents). CDA Header
 
information providing context critical information shall also be rendered in a
 
human readable manner. This includes at a minimum the ability to render the
 
document with the stylesheet specifications provided by the document source, if
 
the document source provides a stylesheet. Content Consumers may optionally
 
view the document with their own stylesheet, but must provide a mechanism to
 
view using the source stylesheet.
 
 
3. Support traversal of links for documents that contain links to other documents managed
 
within the sharing framework.
 
 
4. Print the document to paper.
 
 
=== 3.1.2 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 APSR document (as provided by the sharing framework, along with
 
sufficient metadata to ensure its later viewing). The machine-readable content
 
(from the entry elements) shall also be imported. 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 the document is used after
 
it was imported, a Content Consumer may choose to access the sharing framework
 
to find out if the related Document viewed has been deprecated or replaced.
 
 
=== 3.1.3 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 APSR document (along with sufficient metadata to
 
link the data to its source). The machine-readable content (from the entry
 
elements beneath the imported sections) shall also be imported. 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. When a section is used after it is
 
imported, a Content Consumer may choose to access the sharing framework to find
 
out if the related information has been updated.
 
 
 
 
 
= 4 IHE Anatomic Pathology 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 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 structure of
 
these three tables is presented in '''PCC TF-2:4'''
 
 
 
== 4.1 Anatomic Pathology 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 subsequently
 
being shared. In these cases the context of the CDA document would not necessarily
 
coincide with that of the affinity domain, and the mappings below would not
 
necessarily apply.
 
 
 
=== 4.1.1XDS DocumentEntry Metadata ===
 
 
The general table
 
describing the ''XDSDocumentEntry Metadata'' requirements for IHE domains is shown in '''PCC TF-2:4.1.1'''
 
 
The sub-sections
 
below list the only requirements which are specific to the Anatomic Pathology
 
Domain, and which supersede those from the general table mentioned above.
 
 
==== 4.1.1.1XDS DocumentEntry.formatCode ====
 
 
The values of ''formatCode'' per document template are
 
listed in table 5.6-1.
 
 
The associated'' codingScheme'' Slot SHALL be '''1.3.6.1.4.1.19376.1.2.3''' in all cases.
 
 
== 4.1.1.2XDS DocumentEntry.eventCodeList ==
 
 
This metadata
 
provides a means to index anatomic pathology reports by reportable conditions (e.g.,
 
certain types of tumors…) so as to facilitate later queries in a registry of
 
shared clinical documents. The conclusions coded in the ''entry'' element of the Diagnostic Conclusion section are good
 
candidates for this metadata.
 
 
== 4.1.1.3XDS DocumentEntry.parentDocumentRelationship ==
 
 
The Anatomic
 
Pathology document Content Modules only permit the “replace” relationship
 
between instances of APSR documents.
 
 
Thus, XDSDocumentEntry.parentDocumentRelationship
 
is constrained to the "'''RPLC'''"
 
(replace) value. The new document issued replaces completely the parent one,
 
which will be considered as deprecated.
 
 
=== 4.1.2XDS SubmissionSet 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.
 
 
This content
 
format uses the submission set to create a package of information to send from
 
one provider to another. All documents or images referenced by the Anatomic
 
Pathology Structured Report in this Package must be present (at least as
 
references in the case of images) in the submission set.
 
 
=== 4.1.3XDS Folder Metadata ===
 
 
No specific requirements identified.
 
 
=== 4.1.4 Configuration ===
 
 
The Anatomic
 
Pathology 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.

==5.6 IHE Codes for Anatomic Pathology Document Templates==
 
Any AP structured report SHALL conform to the APSR generic Content Module Identified by templateId “1.3.6.1.4.1.19376.1.8.1.1.1” , and SHALL be associated with the following metadata:
 
*typeCode = “11526-1”, which is the LOINC code for “Pathology study”.
 
*formatCode = “urn:ihe:pat:apsr:all:2010”, with associated codingScheme = “1.3.6.1.4.1.19376.1.2.3” as assigned by the ITI Domain for codes used for the purposes of cross-enterprise document sharing (XDS).
 
*The media type SHALL be “text/xml”.
 
 
 
=6 Anatomic Pathology Content Modules=
 
==6.1 Conventions==
 
In all Content Modules specified in this section, the abbreviation “'''AP'''” stands for “Anatomic Pathology”.
 
 
Various tables used in this section will further constrain the content. Within this volume, the following 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.
 
 
'''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 content 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 content creator requires that information be absent, the R2 section shall be entirely absent. The Content Creator application must be able to demonstrate that it can populate  all required if known elements, unless it does not in fact gather that data. This “R2” code is the equivalent of the HL7 standard “RE” usage code. The value “R2” has been chosen in harmonization with the IHE PCC TF, which is the source of a large number of CDA R2 content modules.
 
 
'''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.
 
 
 
==6.2 HL7 CDA R2 Content Modules==
 
 
===6.2.1 Organization===
 
 
====6.2.1.1 Various Types of Content Modules====
 
 
For the CDA Release 2.0 standard, the content modules are organized by:
 
 
 
*'''document''': The template for a whole document.
 
 
 
*'''section''': The template for a <section> element.
 
 
 
*'''entry''': The template for a <entry> element.
 
 
 
*'''child element''': An element of the CDA header or an element of a <section>, or an element nested at various depths below an <entry>, or an element appearing at some combination of these locations.
 
 
 
====6.2.1.2 General constraints added by IHE PAT to a CDA R2 document====
 
 
In the structured body of a CDA R2 document, a section has a narrative block (the text element), which presents the human-readable content of the section, and MAY have one entry or more.  Sections MAY be nested within one another.
 
 
The content modules designed by the PAT TF bring or highlight the following constraints:
 
 
*When a section has a text element and one or more entry element, the content coded for machine-processing in the entries SHALL be completely transcribed into human-readable content in the text element.
 
 
*Conversely the text element MAY contain pieces of information, which are not available in machine-readable format in any entry element of the section.
 
 
*For a document of the Anatomic Pathology domain, the entry elements are instantiated per specimen or per group of specimens observed together. One entry contains in machine-readable format observations of the section related to the same specimen or group of specimens. Beneath an entry, the observations are organized per problem.
 
 
*The text element of the section is supposed to be also laid out per specimen or group of specimens and per problem observed.
 
 
*The APSR Content Profile leaves the layout of the text element up to the Content Creator applications, or to further constraints brought by national extensions of this profile. However, given that the text element is usually composed of free text (e.g. dictated text), assembled with the text generated from the set of data, machine-encoded in the entry elements below, the Content Creator application MUST handle these two kinds of content, and provide a user interface, which avoids risks of overwriting text automatically derived from the entries with free text typed in by the user  (e.g., using forms with dedicated free text areas and distinct protected areas for text generated out of structured data).
 
 
*Information that is sent SHALL clearly identify distinctions between:
 
 
'''None'''
 
 
It is known with complete confidence that there are none. This indicates that the sender knows that there is no relevant information of this kind that can be sent.
 
 
'''None Known'''
 
 
None known at this time, but it is not known with complete confidence that none exist.
 
 
'''Asked but unknown'''
 
 
The information was requested but could not be obtained. Used mainly in the context where an observation was made but the result could not be determined.
 
 
'''Unknown'''
 
 
The information is not known, or is otherwise unavailable.
 
 
'''Other, not specified'''
 
 
The actual value does not belong to the assigned value set and is not reported at all by the author.
 
 
'''Other, specify'''
 
 
The actual value does not belong to the assigned value set and the author of the report provides this ''foreign'' value anyway.
 
 
'''Not applicable'''
 
 
No proper value is applicable in this context.
 
 
Sections that are required to be present but have no information should use one of the above phrases where appropriate in the ''text'' element.
 
 
Structural elements that are required but have no information shall provide a “nullFlavor” attribute coding the reason why the information is missing.
 
 
{| class="hl7table"
 
!Situation !! nullFlavor !!HL7 Definition
 
|-
 
|Asked but unknown||ASKU
 
||Information was sought but not found
 
 
|-
 
|Unknown
 
||UNK||A proper value is applicable, but not known

||NA||No proper value is applicable in this context
 
 
|-
 
|Temporarily not available
 
||NAV||Information is not available at this time but it is expected that it will be available later.
 
|}
 
 
 
The two situations “None” and “None known” represent effective values, which are part of the related value sets.
 
 
The situation “Other, specify” can be handled in two ways in a coded data element:
 
*Leaving empty the ''code'' attribute and providing the non-coded answer in the ''originalText'' attribute.
 
*Providing a value coded from a different coding scheme, when the coding strength of the element is “CWE” (coded with extensions). The attributes ''code'', ''displayName'', ''codeSystem'' and ''codeSystemName'' then describe the foreign code.
 
 
For ancillary techniques, the situation “ not performed” or “none performed”  is represented by nullFlavor = NAV.

Note 1: In order to facilitate a further de-identification process of CDA AP reports for some secondary use (biosurveillance, epidemiology…) the producer of an APSR SHOULD avoid populating any patient identification data (name, sex, birthdate, address …) into the body of the report (neither <entry> elements nor <text> elements). The appropriate location for patient identification data is the CDA header exclusively.

Each Content Module is uniquely identified by a unique OID.
 
 
=====6.2.2.1.1 Definition and purpose=====
 
 
This section presents the content module and its purpose.
 
 
In case this module is a specialization of a more generic one, the section references its parent template.
 
 
=====6.2.2.1.2 Example=====
 
 
This section delivers a snippet, showing an example of the content module.
 
 
=====6.2.2.1.3 Specification=====
 
 
The form of the specification depends upon the kind of CDA Content Module (document, section, entry, header and/or entry element). It respects the guidelines below:
 
 
*The specification provides a table describing the structure of the content module, each element being located through an XPATH expression combined with indentation. The table provides cardinalities, meaning for each elements, references value sets described in section 5 for attributes, and provides the mapping with HL7 V2.5.1 relevant fields. The table also points the content modules nested in the current one, by showing their templateId, and locating their specification in the current PAT TF-3 or in the IHE TF they belong to (PCC, LAB, etc.).
 
*The table is simplified for section content modules: It only lists the content modules nested in the section template.
 
*Below the tables appear notes providing additional information and detailing particular constraints on some elements or attributes.

=====6.2.6.3.1 Definition and purpose=====
 
 
This Content Module is usable only in the CDA header.
 
 
It describes a pathologist having verified the content of the report, using the element authenticator. This element authenticator is used when the pathologist having verified the content of the report is distinct from the pathologist assuming the legal responsibility for this report, described in the legalAuthenticator element.
 
 
The report MAY have zero or more Content Validators.
 
 
 
 
====6.2.6.4 Specimen Information Organizer – 1.3.6.1.4.1.19376.1.8.1.4.4====
 
 
=====6.2.6.4.1 Definition and purpose=====
 
 
{{FAQBox|
 
Is this organizer really necessary? The updated AP Observation has direct relation to a specific specimen which is observed. The central organizer function should be fulfilled by the problem organizer. GH
 
}}
 
 
This Content Module is the unique <entry> available for most of APSR sections (see figure 4.1.2.1-1 in Volume 1). The specimen information organizer organizes information related to the various acts (procedures, observations) performed on a single specimen or group of specimens investigated together.
 
 
 
 
====6.2.6.5 Specimen Collection Procedure generic template – 1.3.6.1.4.1.19376.1.3.1.2====
 
 
=====6.2.6.5.1 Definition and purpose=====
 
 
{{FAQBox|
 
Is this entry really necessary? Its function is better served by the Specimen Procedure Steps entry. GH
 
}}
 
 
This Content Module is usable within an <entry> element.
 
 
This Content Module structures the machine-readable data representing the characteristics of the specimen (identifiers and type) and the procedure that collected it: Type of procedure, time interval, performer (person and organization), approach site, target site.
 
 
The “Specimen Collection Procedure” generic template is usable in all <entry> elements of all APSR Document Content Modules.
 
 
Each organ-specific APSR Document Content Module mandates an organ-specific template, child of the “Specimen Collection Procedure” generic template. This organ-specific child template has exactly the same structure as the generic one, and brings only a number of vocabulary constraints related to this specific organ:
 
*The value set bound to the procedure/code element, consisting in a list of triplets (code, codeSystem, displayName) representing the various specimen collection procedures that can be performed on this specific organ.
 
*The value set bound to the procedure/targetSiteCode element, consisting in a list of triplets (code, codeSystem, displayName) representing the various precise locations for collecting specimens from this specific organ.
 
 
 
Thus, a specimen collection procedure in an <entry> within an organ-specific APSR Document Content Module declares conformance to two templates: The “Specimen Collection Procedure” generic template and the “Specimen Collection Procedure” child template constraining the vocabularies for the contextual organ.
 
 
These specimen collection procedure child templates and their attached value sets are provided by the appendix “IHE_PAT_Suppl_APSR_AppendixValue_Sets.xlsx”
 
 
 
 
====6.2.6.6 Informant – 1.3.6.1.4.1.19376.1.8.1.4.6====
 
 
=====6.2.6.6.1 Definition and purpose=====
 
 
This Content Module is usable in the CDA header, in a <section> and within an <entry>.
 
 
It describes a person having provided some piece of relevant information for the document.
 
 
A <ClinicalDocument> or a <section> or any kind of act below an <entry>, MAY have zero or more informant.
 
 
 
 
====6.2.6.7 Additional participant in an entry - 1.3.6.1.4.1.19376.1.8.1.4.7====
 
 
=====6.2.6.7.1 Definition and purpose=====
 
 
This Content Module is usable only within an <entry> element.
 
 
Additional participants MAY take part in any organizer as well as in any observation of an APSR. These participants MAY be any of these 4:
 
*Validator: This is the same participation as Content Validator in the header of the report: a pathologist having verified the content (of this particular subset of results). 
 
*Device: A device used to produce this particular subset of results.
 
*Responsible: The director of a laboratory (described in a performer element at the same level) who produced this particular subset of results.
 
*Transcriptionist: This is the same participation as dataEnterer in the header of the report: a staff who entered, possibly from dictation, this particular subset of results.
 
 
 
 
====6.2.6.8 Problem Organizer – 1.3.6.1.4.1.19376.1.8.1.4.8====
 
 
=====6.2.6.8.1 Definition and purpose=====
 
 
This Content Module is usable within (a Specimen Information Organizer) any Section module.
 
 
The problem organizer groups the battery of observations performed to investigate on a single problem identified on a specimen or group of specimens.
 
 
 
 
====6.2.6.9 AP Anatomic pathology Observation template – 1.3.6.1.4.1.19376.1.8.1.4.9====
 
 
 
=====6.2.6.9.1 Definition and purpose=====
 
 
This Content Module is usable within a Problem Organizer.
 
 
The “AP Observation”generic template is usable for all AP observations, including ancillary
 
techniques.
 
 
 
Each specific AP observation is associated to a specific template, child of the “AP Observation”generic template. This specific child template has exactly the same structure
 
as the generic one, and brings only a number of vocabulary constraints related to the type of observation and to the type of organ source of the specimen
 
observed:
 
*The code for the specific observation, defined as a value set bound to the ''observation/code'' element, containing a single triplet (code,
 
codeSystem, displayName) representing this specific observation.
 
*The cardinalities and default type for the ''observation/value'' element carrying the results of this observation.
 
*The domain of values for this observation in case these values are coded. This domain of coded values is defined as a value set bound to the
 
observation/value element, containing as many triplets (code, codeSystem, displayName) as there are admissible result values for this specific observation
 
performed on a specimen taken from this specific organ.
 
 
An AP Observation has a status and an effective time, may describe various participants (persons, devices, organizations), may have a number of additional properties (method,
 
interpretation, text), and may contain embedded images, comments, and sub-observations, which are also AP observations.
 
 
 
 
 
 
====6.2.6.10 Embedded Image – 1.3.6.1.4.1.19376.1.8.1.4.10====
 
=====6.2.6.10.1 Definition and purpose=====

=====6.2.6.11.1 Definition and purpose=====
 
The Specimen Procedure Step <entry> Content Modul contains in machine-readable form all the information concerning one specimen or a group of specimens. It is usable within a Procedure Steps <section> Content Module only.
 
 
This Content Module structures the machine-readable data, which characterize the specimens and the procedures of their collection and processing. By nesting via an entryRelationship the entry is used in an iterative manner for each single step of specimen processing, which results in derived (child) specimen in and on the appropriate containers. The resulting specimen is the participant in the procedure according the CDA-RIM (fig. 6.2.6.11.1-1). It carries an ID as well as further attributes, which are defined in the HL7 Specimen DAM [http://www.hl7.org/implement/standards/product_brief.cfm?product_id=331 HL7 DAM Specimen Release 1].

Foreword

This is a supplement to the IHE Pathology and Laboratory Medicine Technical Framework V8.0. Each supplement undergoes a process of public comment and trial implementation before being incorporated into the volumes of the Technical Frameworks.

This supplement was published on September 27, 2017 for Public Comment, with a comment period extending to mid-November. The current content is the Trial Implementation version, which has taken in consideration the comments received.

This supplement describes changes to the existing technical framework documents.

“Boxed” instructions like the sample below indicate to the Volume Editor how to integrate the relevant section(s) into the relevant Technical Framework volume.

Replace Section X.X by the following:

Where the amendment adds text, make the added text bold underline. Where the amendment removes text, make the removed text bold strikethrough. When entire new sections are added, introduce with editor’s instructions to “add new text” or similar, which for readability are not bolded or underlined.

Closed Issues

APSR-07 – Representing the hierarchy of specimens in an entry : This APSR supplement enables to represent the hierarchy of specimens at the CDA level 3. The operations on specimen and production of child specimens are tracked in the “Procedure Steps” section, which has a level 3 entry.

APSR-10 – Observation related to multiple specimens: For example tumor staging may require combining data from multiple specimens (e.g., a breast excision with positive margins followed by a re-excision with clear margins – in this case the tumor size may be a composite of measurements from both specimens. Another example is staging of ovarian carcinomas with multiple biopsies of pelvis, peritoneum, nodes, omentum, etc.). To accommodate these use cases, each problem organizer as well as each observation may reference any number of specimens using the <specimen> child element. Each of these references may point to a detailed description of the specimen, in the "procedure steps" section.

APSR-11 – Derivative specimens:Specimens derived from primary specimens for ancillary studies, which may be sent to a reference lab or done in another part of the same institution, are included in the scope of this profile. The results produced on a derived specimen are attached to this specimen in the report.
