Order interaction for the creation of a document

Summary

This proposal documents a new set of HL7 version 3 interactions related to 'ordering the creation of a document'. The document could be of any mime-type, and could have a structured or a non-structured content. The focus will be on structured CDA (and more general: SDA) documents, but this should not preclude the interactions from being used for other documents.

The newly created set of interactions should be part of the composite order (POOR) domain.

Use-case

• Sending an order to request for the (human) creation of a clinical summary report; sending an order to request the creation (by a software application) of a lab result report.

Dutch Storyboards

• (use case 1) Gerald General, a GP is informed (exactly how is out of scope of this simplified use-case description) that Patient Eve Everywoman has had an encounter with Radiologist Dr. Röntgen and Gynaecologist Dr. Gerard, both in the same hospital. Given that the GP has a responsibility in the provision of continuous care to the patient he sends an order for a 'consultant summary' to Dr. Röntgen, and another order for a 'consultant summary document' to Dr. Gerard. Dr. General stores the documents (and the information contained therein) in his GP system. When Eve shows up for a future GP consultation Dr. General has access to the data generated during the hospital encounter.
• (use case 2, minor variation) Irvin Internist, a specialist in the area of internal medicine, is informed (exactly how is out of scope of this simplified use-case description) that Patient Eve Everywoman has had a prior encounter with another Internist Dr. Iznogood in a different hospital. Dr. Internist sends an order for a 'consultant summary document' to Dr. Iznogood. Dr. Internist stores the document (and the information contained therein) in his software application. When Eve shows up for a future encounter with Dr. Internist he has access to the data generated during the prior encounter.

Dynamic Model

In terms of Dynamic Model and Trigger Events the newly proposed Topic conforms to the general Orders and Requests Pattern as defined by the Orders and Observations WG. That design pattern will be used as the basis for this topic.

Question: why an order, why not a query? A query requests that an existing document be sent to the querying party - the result of which may be 'there are no documents that match your query parameters'. In order requests the execution of a workflow: the creation of a new document.

Static Model

The static model used in the order interactions has to indicate various items of metadata related to the document that should be created (e.g. requested document type, requested author, requested templates the document should conform to, patient id, etc.).

Requirements related to the static model:

• The basic model (refined by further discussions) could be defined to be the CDA Header model, with the focal DOCCLIN Act in RQO mood.
• The final model should be in compliance with the Composite Order model (as defined by the Orders and Observations WG). The current Compsite Order model may have to be updated to support the ordering of documents.

Table 1 Items relevant for a document order

Grouping	Request item	Notes	Composite Order model (order interaction)	CDA R2 (response document)
Structure	Document.code	The requested document type.	Act(DOCCLIN/RQO).code (new: DOCCLIN/RQO to be added as one of the Acts in the main choice box)	ClinicalDocument.code
Structure	Document.templateID	Set of template IDs the document creator is requested to adhere to (only applicable for structured documents).	Gschadow: This does not work, templateID is not part of the information model, just something that specifies the template for the structure that you send, i.e., in this case the structure of your order. Rene spronk True. We won't be able to support this part of the use case.	not available
Structure	Document.mimeType	The mime type the document creator is requested to create (if equal to application/hl7-v3-sda templateIds will have to be used to identify CDA R2, CDA R3, SPL, etc.).	(New, not in current POOR model: DOCCLIN DEF Act -- INST act relationship -- DOCCLIN RQO (focal act)). Act(DOCCLIN/DEF).text	ClinicalDocument.text (although that attribute doesn't exist in CDA R2). There is a precedent for text to be used to solely convey the mime type, see ParentDocument.text
Structure	Document.language	The document language the document creator is requested to use.	(New, not in current POOR model: DOCCLIN DEF Act -- INST act relationship -- DOCCLIN RQO (focal act)). Act(DOCCLIN/DEF).languageCode	ClincalDocument.languageCode
Subject	Activities.effectiveTime	An interval of time for the data which should be reported on/documented.	subject Act(EVN) Note: No, it's not NOT Act(DOCCLIN/RQO).effectiveTime	ServiceEvent.effectiveTime, effectiveTime of entry-level Acts
Subject	MainActivity.id	ID of the main (focal) requested/performed act.	subject Act(EVN) ;sourceOf(Actrelationship of type XXX)/requested Act.id (new: subject to ACT(EVN) to be added, the current model is limited to role based subjects)	ServiceEvent.id, Order.id
Subject	MainActivity.code	Type of the main (focal) requested/performed act. May be used if there is no known MainActivity.id	See MainActivity.id	ServiceEvent.code, Order.code
Subject	Encounter.id	The encounter.ID of the encounter which should be reported on/documented.	subject Act(EVN) ;sourceOf(Actrelationship of type XXX)/requested Act.id	EncompassingEncounter.id
Subject	Encounter.code	The type of encounter which should be reported on/documented. May be used if there is no known Encounter.id	See Encounter.id	EncompassingEncounter.code
Subject	RecordTarget.id	RecordTarget (mostly: Patient) identifier.	recordTarget/R_Subject.id	PatientRole.id
Subject	ReferencedDocument.id, Documentrelationship.code	Identification of a referenced document - the document author is requested to create a document which is a transformation/update/appendix (as specified by Documentrelationsip.code) of the ReferencedDocument.	See section "Requesting a translation of a document" below for discussion	relatedDocument/ParentDocument.
Author	Author.id	Who (as an identified Role) is asked to create the report (person/organization/software application).	performer/(Role).id	AssignedAuthor.id
Author	Author.code	Who (of what kind) is asked to create the report (person/organization/software application). The underlying use case is one whereby one would like 'a lab physician' to write the report without the requirement to identify an individual.	performer/(Role).code	AssignedAuthor.code
Recipient	Recipient.id	If other than the author of the order to create a document. "resulting document to:"	callBackContact/R_NotificationParty	IntendedRecipient.id
Timing	Order.priorityCode	The priority of the order to create a document	Act(DOCCLIN/RQO).priorityCode	n.a.
Timing	MainActivity.status	Status code of the main (focal) Act. Example: when sending a lab order jointly with an order to create a document with the labresults, one may want to specify that a document should only be created once the status of the lab observation is 'completed' - and nothing before that point in time. The Composite Order model has a mechanism to indicate that one order should be performed after (SUCC act relationship) another order.	sourceOf(Actrelationship of type SUCC)/requested Act.id	ServiceEvent.statusCode (although that attribute doesn't exist in that class), status of the Entry-level acts.

Requesting a translation of a document

• Discussion in MnM 2010-01-22, Lloyd suggests that this use case be coveredy by a different model, one that has the entry point on a (Translation RQO) act, with subject (referencedDocument), and instantiates relationship with a DOCCLIN/DEF (for the requested language or mime type). Different R-MIM if we feel strongly about the use case.

WGM Phoenix, OO-Working Group 2010-01-20

• Proposal was presented.
• Harry Solomon talks about a use-case whereby the result of the order is a Document Set. This wasn't part of the original set of use-cases, but we could try to ensure that the response model supports 1..* documents.
• MOTION: In principle this topic fits with the OO Composite order domain, and OO will address how to progress this in a project. (Rene/Patrick, 13-0-1).
  • The current composite model project statement will be updated to include 'the POOR domain model will be extended to support the ordering of the creation of a document'.
• Rene indicates that there is currently no urgent requirement for implementation, so having a solution in the D-MIM would be sufficient. In other words: no special Topic, no interactions, no R-MIMs.
• Rene to create an R-MIM which acts as a focal point for discussion. Will be discussed on an OO teleconference call, and during the Rio WGM in May 2010.

R-MIM

Note: some of the act relationships may point in the wrong direction. The model should suffice to get an idea of what it would take to satisfy the use-cases documented above.

Discussion related to the R-MIM

• Charlie McCay: This is very like the usecase being addressed by ISO/CEN 13606:5 - is there

any chance of this being a combined effort?
