What is PITO?
• Set up by the BC Medical Association (BCMA) and the BC government as
part of their 2006 agreement. Currently have a mandate to March 2014.
• PITO’s primary responsibility is to support the adoption and use of
electronic medical records (EMRs) in physicians’ offices across BC.
• PITO assists physicians during pre-implementation planning,
implementation, and post-implementation, and coordinates the
disbursement of IT funds to physicians as defined in the agreement.

EMR-to-EMR Data Transfer & Conversion Specification (E2E-DTC)
WHY THIS PROJECT?
2013-May-28
PITO & GPi
11
Why this Project?
• Locked Data = Barrier to Collaborative Care
– Gaps in EMR data standards as well as a general
lack of thorough vendor adoption risks locking
critical clinical data inside
EMR systems
– This continues to present
a barrier to effective clinical
collaboration as well as
EMR migration
2013-May-28
PITO & GPi
12
Why this Project?
• To address this issue, PITO sought the
development of a strategy to establish – by
adoption, adaptation or, if necessary,
development – a specification to support:
– Transfer of data when a physician changes from one
EMR system to another (“Conversion”);
– Transfer of data when a patient moves from one
family physician to another, or one long-term
specialist physician to another; e.g. a diabetic
transferring from one endocrinologist to another
(“Transfer”); and
– Transfer of data with a referral or consult request and
report, to populate or update the records of the
receiving physician (“eReferral”).

Phase III – Implementation: Pilots, Vendor Incentives, etc.
WHAT DID WE DO?
2013-May-28
PITO & GPi
14
Phase I – Environmental Scan:
Options & Recommendations
• Option analysis report
– Initially completed in Early 2011
/ Refreshed October 2011
• Environmental Scan
– Reviewed key specifications
•
•
•
•
•
•
•
Alberta's ToPD and CoPD specifications (collectively referred to as TCoPD);
Vancouver Island Health Authority's Electronic Medical Summary (e-MS);
The Data Portability Requirements (Appendix B) of OntarioMD's Clinical Management Systems (CMS)
Specification;
HL7's & ASTM International’s Continuity of Care Document (CCD) specifications; and
England’s National Health Service’s (NHS) GP-2-GP specification.
ASTM International was formerly known as the American Society for Testing and Materials (ASTM)
Other pan-Canadian Specifications including CIHI PHC and Infoway standards
– Other initiatives (e.g. BC Interior Health “EHR Integration – CCD Standard for Results
Distribution”)
– BC Vendor and Stakeholder dialogue
• Established key recommendations
– Various recommendations pertaining to collaboration and engagement
– Specific technical recommendations …

16
Phase I – Environmental Scan:
Options & Recommendations
• Key Take-Away Points
– Beg, borrow and steal … but make “incremental”
improvements
•
•
•
•
Take the best from other specs
Fix issues
Don’t invent things that don’t need inventing
Move forward
– Think “platform and foundation” … Focus on today
but build for the future
2013-May-28
PITO & GPi
17
Phase II – Collaborative Spec Development
• Rapid Timeline
– December 2011 – May 2012
• Full Collaboration
– Established Clinical and Vendor Stakeholder
Panels
– Reviewed requirements with stakeholders based
on specific subject areas
– Adjusted Specification Strategy to focus on
“document paradigm” – given practical advice
from conversion experts, stakeholders and other
key examples in the market place
2013-May-28
PITO & GPi
18
Phase II – Collaborative Spec Development
• Tooling and Development
– Briefly Assessed CDA tools including
• Trifolia WorkBench
• Model Driven Health Tools (MHDT) for CDA
• … but not … DECOR (Data Elements, Codes, OIDs and
Rules) Infrastructure
– Devised a prototype constraint tool for better
control over the model and the output
– Built Draft Specification using the tool
2013-May-28
PITO & GPi
19
Phase II – Collaborative Spec Development
• Key Take-Away Points
– Involve vendors / developers as early as possible
– Use tools to improve the “state of the art” of
building and publishing specifications
– Consider a framework, such as CDA, which has
adoption, market traction and – perhaps most
importantly – provides an on-ramp that positions
for “progressively deeper” data exchange over
time!

– UBC/UVIC Primary Care Informatics LEAD Lab –
also working with the BC Physician Data
Collaborative PDC
– Nanaimo Division of Family Practice eReferral Pilot
– Prince George eReferral Pilot
– … others …

WHAT IS THE RESULT?
2013-May-28
PITO & GPi
22
Key Outcomes to cover
• A “new” approach to CDA Development
• … with a fairly comprehensive clinical content
model.
• Constructive early feedback from developers
• … to allow change / improvement.

Brief Detour – What is CDA …
•
The Clinical Document Architecture (CDA) is:
– a document markup standard for the structure and semantics of an exchanged "clinical
document".
– documentation of observations and other services.
•
•
•
•
A CDA document is a defined and complete information object that can exist
outside of a message, and can include text, images, sounds, and other multimedia
content.
CDA hits the “sweet spot” – CDA encompasses all of clinical documents. A single
standard for the entire EHR is too broad. Multiple standards and/or messages for
each EHR function may be difficult to implement. CDA is “just right”.
Implementation experience - CDA has been a normative standard since 2000, and
has been balloted through HL7's consensus process. CDA is widely implemented.
Gentle on-ramp to information exchange - CDA is straight-forward to implement,
and provides a mechanism for incremental semantic interoperability.
– Level 1 – Structured Header + Blob
– Level 2 – Structured Header + Sections
– Level 3 – Structured Header + Structured Sections
•
Improved patient care - CDA provides a mechanism for inserting evidence-based
medicine directly into the process of care (via templates), making it easier to do
the right thing.
Heavily abridged from HL7 Materials!

A Use-Case-Driven, Canadian focused
Consolidated CDA Spec
•
Uses the HL7 Clinical Document Architecture
(CDA) template model
–
•
Adheres to the latest global best practice in the
structure and design of Clinical Document
Architecture (CDA) specifications
–
–
–
•
Leverages the style approach used by the IHE / HL7
Consolidated CDA guide emerging from the US
Health Story project
(http://www.healthstory.com/index.html)
Establishes explicit, testable conformance criteria.
See
http://www.hl7.org/implement/standards/product
_brief.cfm?product_id=258
Follows HL7 RIM to offer a degree of consistency
with pan-Canadian standards
–
•
Forces consistency across several “document”
specifications that are intended to support a variety
of uses cases including EMR-to-EMR conversion,
Patient Transfer, and other diverse data exchanges
via either a General Episodic Document or an
Unstructured Document (e.g. PDF).
Note that this is imperfect given compatibility
issues between CDA R2 and message based
specifications)
Tooling driven for precision, comprehensiveness,
and traceability!

• Specific document
templates defined:
– EMR Conversion Document
– Patient Transfer Document
– Generic Episodic Document,
and
– Unstructured Document
• e.g. container for other
content such as PDF.
First two are targeted at the
respective use cases.
The last can be used to support
any process (e.g. eReferral).
• These document specs build
on a library of common
Section, Section Entry, Entry
and Data Type templates …
2013-May-28
… and tries to follow best practices of alignment
and precision …
• Header aligned with (but slightly expanded from) BC Interior
Health specification - a parallel project covering a different
set of use cases
• Consistently enumerated, testable Constraint Statements
against the formal CDA R2 model
• Explicit Vocabulary Bindings that leverage HL7,
Infoway/Standards Collaborative & (soon) PHC RefSets
through integration
• Purposeful use of formal conformance language while
retaining developer friendly tabular views
• Integrated XML examples
• Comprehensive cross-referencing and “hot links”

Initial Learning
• LEAD Lab Feedback
– Pinpointed challenges to certain parts of the specification
– Many QA points but also some issues; key among these
was “Medication” model and gaps in various vocabulary
areas
– Billing data exchange is likely an unexpected gap
• Nanaimo Feedback
– Level 1 only … with minor changes identified to header
– Works … and is almost live in production!
• Other Realities
– The world has moved forward with the introduction of, for
example, PHC RefSets …

Next Steps?
• Specifications are available through PITO web site
– a Revision that addresses feedback from early
adopters and adds new terminology details will be
published shortly together with “test/sample”
documents
• Technical support mechanism for vendors has
been established
– additional funding for vendor implementation has
been established
• Initial projects are continuing and …
– There are currently 4-6 eReferral Pilots in the early
stages of implementation that will further leverage
and test the specifications
