Impact on Healthcare and Drug
Information
• Steve Ruberg, Applied Clinical Trials,
February, 2002:
“The essential kernal of the whole clinical
development processs is the data… Thus,
without a data-centric approach to
developing any e-clinical solution, we are
unlikely to be fully successful. The data is
the foundation on which we build our
entire effort.”
Single Source: Starbrite Trial
Business Drivers
• Need to shorten cycle time of drug
development:
– Drug company R & D is too high;
– Government pressure.
• Drive for personalized, prospective
medicine.
• Patient and investigator convenience.
• HHS desire to link research data to
physician behavior.
• Rationalize provider document workflow.
Single Source: Starbrite Trial
Project opportunities
• Starbright – a small clinical trial at
Duke’s Clinical Research Institute
(DCRI)
– DCRI’s Data Mgt and IT groups are
cooperating with the trial’s investigator.
– Goal is to capture both patient care and
clinical trial data at the front end, and
populate both data streams, using CDA
and CDISC standards
Single Source: Starbrite Trial
Obstacles
• Two different world views between
patient care and clinical research:
– Bio-statisticians want perfect data;
– Clinicians want everything they can grab.
• Lack of a structured vocabulary.
• Privacy concerns.
• CDISC, HL7 divergent data models

Clinical Data Interchange
Standards Consortium
CDISC is an open, multidisciplinary, non-profit
organization committed to the development of
worldwide industry standards to support the
electronic acquisition, exchange, submission and
archiving of clinical trials data and metadata for
medical and biopharmaceutical product
development.
The CDISC mission is to lead the development of
global, vendor-neutral, platform-independent
standards to improve data quality and accelerate
product development in our industry.
Single Source: Starbrite Trial
CDISC
• Formed in 1997 as a volunteer group
• As of 2000, funded as non-profit
organization
• Now supported by >140 corporate
members: pharmaceutical companies;
biotech companies; CROs; technology
providers
• CDISC Groups now growing in Japan,
Europe; initiated in India
• Standards developed through consensusbased approach by teams of volunteers;
public reviews
• No fee for use of the standards; freely
available on CDISC website (www.cdisc.org)
Single Source: Starbrite Trial
ICH and CDISC
• CDISC developed standards for submission of
clinical trial data, which was beyond the scope
of ICH since only FDA requires that data be
included in regulatory submissions at this time.
• The current plan is for FDA to reference the
HL7-approved CDISC Submission Data
Standards (SDS) as a specification in their
FDA Guidance on the implementation of the
ICH electronic Common Technical Document
(eCTD).

• Version 2.x
– used worldwide, 90% of US hospitals
– “pipe & hat”: HL7-proprietary, EDI-like
PID||2247^^^Primary|098018500^^^MRN||FIX
-INTF^PAT||19650618|Female|
• Version 2.XML
– a normative XML encoding for V2

HL7 Standards
• Version 3
– based on Reference Information Model
(RIM)
– technology independent: so far,
developing XML schemas, JAVA API
• RCRIM/CDISC lab reporting is a V3
draft standard, as is SPL
• First normative V3 spec was CDA
Single Source: Starbrite Trial
Single Source: how is it
different?
• eSource & electronic data capture (EDC)
–
–
–
–
redundant with creation of clinic note
full burden lies on investigator
require that information reside in EMR
proprietary data formats
• CDA & CDISC in “single-source”
– capture trial data, merge it into clinic note (reuse)
– works with current technology, workflow (EMR
optional destination, not required)
– open, non-proprietary data formats
– XML bridging disparate data models

CDA & CDISC in Starbrite Trial
• System features/requirements:
•
•
•
•
multi-stage, incremental document creation
optimal re-use (minimal redundant entry)
minimal change to current workflow
create both ODM-compliant XML for trials
and CDA-compliant XML for clinical records,
mapping between ODM.xml and CDA.xml
• low cost
• rapid development
• optimal use of technology partners, off-theshelf technology
Single Source: Starbrite Trial
XML-encoded information
• With a few simple tags, and controlled
vocabulary, XML can describe anything
• but…
• the tags need to be defined:

CDA: Release 1.0
• priority is patient care, other
applications facilitated
• minimize technical barriers to
implementation
• promote longevity of clinical records
• scoped by exchange, independent of
transfer or storage
• enable policy-makers to control
information requirements

The CDA document defined
CDA Release 2 (draft), section 2.1:
A clinical document ... has the following characteristics:
 Persistence
 Stewardship
 Potential for authentication
 Context
 Wholeness
 Human readability
“Context - Contents of a clinical document share a
common context unless all or part of that context is
overridden or nullified.”
(material in blue is quoted from the
Clinical Document Architecture Release 1.0)
Single Source: Starbrite Trial
Requirements for a universal
clinical document
• Span full range of technical
sophistication
• Minimal constraint on content
• Makes all types of information human
readable and, to the greatest extent
possible, also machine processible
Single Source: Starbrite Trial
CDA::Readability
• CDA documents are “human readable” =
– This principle means that CDA documents are
human readable using:
a) widely-available and commonly deployed XMLaware browsers and print drivers and
b) a generic CDA style sheet written in a
standard style sheet language.
• CDA documents are also “machine
processable” to the degree that markup has
been added
– required markup provides initial functionality
– optional markup can augment processing

CDISC ODM
• Operational Data Model
– ver. 1.1, April, 2002
– www.CDISC.org
• Defined by set of XML DTDs
• A database insertion schema
Single Source: Starbrite Trial
CDISC ODM
• The technical focus in the development of
ODM 1.0 was the definition of structures
to represent the three major information
components relating to a clinical trial:
– clinical study metadata (item definitions and
protocol)
– clinical study administrative data (users and
access privileges)
– clinical study data (complete record of patient
data and audit trail)
Single Source: Starbrite Trial
CDISC ODM
• Study allows representation of more than one
study in a single file
• AdminData includes information about the users
of the system, the clinical sites involved in the
study, and associated security information
• ReferenceData provides information relevant to
the interpretation of data that is not necessarily
study specific, such as lab normal ranges
• ClinicalData contains the actual data item values
associated with each study.

• Simple encoding relatively inexpensive
• Complex encoding costs more
• You get what you pay for:
– like charging a battery,
– the more detailed the encoding
– the greater the potential for reuse

– And send them in a common exchange
framework?
82
ASTM CCR + HL7 CDA =
CCD
• CDA is designed to support professional society
recommendations, national clinical practice
guidelines, standardized data sets, etc.
• From the perspective of CDA, the ASTM CCR is a
standardized data set that can be used to constrain
CDA specifically for summary documents.
• The resulting specification, known as the
Continuity of Care Document (CCD), is being
developed as a collaborative effort between ASTM
and HL7.

Continuity of Care Document
• “ASTM is dedicated and privileged to
work in collaboration with HL7 on the
expression of ASTM's Continuity of
Care Record content within HL7's CDA
XML syntax and the seamless
transformation of clinical and
administrative data between the two
standards.”
• Rick Peters, MD, E31.28

CDA & CCD
• IHE Profiles 2005-2007 based on the Care
Record Summary (CRS)
– first standard implementation guide for CDA
– restricted to “level 2” to avoid competition w/CCR
– covered a wider number of use cases
• IHE 2007-2008 will move to conform with
CCD
• New CDA implementation guides also
conform with CCD
ASTM CCR+HL7 CDA = CCD
• The primary use case for the ASTM CCR is to provide a snapshot in time
containing a summary of the pertinent clinical, demographic, and
administrative data for a specific patient.
• From its inception, CDA has supported the ability to represent professional
society recommendations, national clinical practice guidelines, standardized
data sets, etc.
•From the perspective of CDA, the ASTM CCR is a standardized data set
that can be used to constrain CDA specifically for summary documents.
•The resulting specification is known as the Continuity of Care Document
(CCD).
Continuity of Care Document
• CCD maps the CCR elements into a CDA representation.

CDA Business Case
• Gentle on-ramp to information exchange - CDA is straight-forward to
implement, and provides a mechanism for incremental semantic
interoperability.
• Improved patient care - CDA provides a mechanism for inserting
best practices and evidence-based medicine directly into the process of
care (via the same “template” mechanism used to build CCD), thereby
making it easier to do the right thing.
• Lower costs – CDA provides necessary information to coordinate care,
reducing redundant testing and optimizing care delivery for quality and cost.
• 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”.
CDA beyond CCD
• Not everything we want to exchange is
a summary
• Let’s look at what’s happening with
development of other document types...
Other CDA content profile
development
– Within HL7:
• Clinical domains: anatomic pathology, imaging, lab,
anesthesiology, pediatrics, long term care, others?
• ASIG: HIPAA Attachments – adding dental
– Outside HL7: Public health & MDS
• NAACCR Cancer abstracts (no HL7 ballot)
• CDC Infectious Disease Reports (will be HL7 ballot)
• MDS: soon, from HHS
– IHE
• 2006: 1 content type built on HL7 CRS
• 2007: 7 content types, some constrain CRS, others
new
• Current cycle:
– updating all to be consistent with CCD
– adding Discharge Summary
– CDA4CDT
CDA for Common
Document Types
• Project initiated in January, 2007
– M*Modal
– AHDI(was AAMT)/MTIA
– AHIMA
• Strong support from dictation / transcription
and document management industries
• Cooperation/coordination with HL7, IHE,
EHR vendors and providers
CDA4CDT Mission
• Develop CDA Implementation
Guides (IGs) for common types of
electronic healthcare documents
• Bring them through the HL7 ballot
process
• Promote their use and adoption by
healthcare organizations and health
information exchange networks
Rationale
• Enlarge and enrich the flow of data
into the electronic health record
• Speed the development of
interoperable clinical document
repositories
• Bridge the gap between narrative
documents produced through
dictation and the structured,
computable records within an EHR
Why would physicians promoting
the EHR have an interest in
documents?
• Assumptions:
– EMR/EHR is the solution
– Documents are the problem
• Questions:
– Are they mutually exclusive or
complementary?
– Can eDocuments bridge the gap?
Problems with Documents
• Can’t compute
• Can’t automate decision support
• Can’t validate conformance to content
requirements
• And why are they still prevalent?
–
–
–
–
Nuanced & precise
Support human decision making
Retain current workflow
eDocuments support narrative & codes
• multiple indices optimized for reimbursement, decision
support, quality metrics, research
• Document management completes the EMR
Why encourage continued
use of documents?
• Worst case:
– no computable clinical data
– no reuse
– + information at the point of care
• Best case:
– fully computable data to populate EHR
• Likely case:
– section-level reuse (i.e. HPI pre-populates
Discharge Summary) – we can do this now
– gradual rise in semantic interoperability
Why not keep pushing for
fully interoperable records?
• Semantic interoperability is hard
– over 250,000 concepts in SNOMED CT
– we can’t give up, we need safe computability
• Need information at the point of care
• Networks need data: self-sustaining networks
have Big Data
– Initial ROI will spur further investment
– MTIA members process 300M documents/year
• Complex systems are built from simple systems
• CDA: no loss of computability
minimum
metadata
today
future
CDA4CDT: bridging the gap
between EHRs and eDocuments
• CDA4CDT will:
– Establish consensus on content using CDA eDocument
format
– Propagate support for CDA within the dictation/transcription
industry
– Create consistent electronic documents for importation into
EMR, document repositories and health information
exchanges
– Increase EMR adoption
• Highest potential:
– Massively increase amount of data in fledgling exchange
networks because minimally disruptive to current workflow
• Defining success:
– At least 25% of RFPs for transcription, EMRs, integration and
information exchange cite compliance as a requirement
CDA4CDT
• Scope
– Develop implementation guide for use across the industry
– Rapid development, leverage framework, precedents
– Establish section-level content, reuse section templates
• H&P Timeline
– Initial draft in 7 weeks
– Balloted as HL7 Draft Standard for Trial Use
• March 26 ballot open, April 24 close
• Ballot reconciliation approximately 5 weeks
• Revised draft to ballot in August
• Consult Note Timeline
– Target August 2007 initial ballot
• Discharge Summary: Coordinating with IHE on
publication
– Target publication fall 2007
Technical working group
• A focused group of working volunteers
– prior knowledge of CDA
– experience implementing CDA
– familiarity with the current set of CDA
implementation guides
• Participation is open at all stages of the
ballot and ballot review process
• CDA4CDT retains no copyright of
balloted material
H&P Method
• Review precedents:
– ASTM’s Standard Specifications for Healthcare Document Formats
(E2184.02) (Headings and subheadings used in the healthcare
industry and associated with specific report types)
– HL7/ASTM Continuity of Care Document (CCD)
– Clinical LOINC document and section codes
– HL7 ASIG CDA R2 Attachment for Clinical Notes
– HL7 Care Record Summary (CRS)
– IHE profiles, including the content profiles within Patient Care
Coordination
– MHS/DoD-VA-IM-IT Demo Project Discharge Summary and SOAP
HL7 CDA R2 Implementation Guides
• Review samples/templates:
– Sample CDA documents developed for local provider institutions
(Mayo Clinic, University of Pittsburgh Medical Center, New York
Presbyterian, and others)
– Non-CDA sample documents supplied by participating providers
and vendors
– H&P templates from AHIMA, vendors, providers
• Statistical analysis: over 15,000 dictated H&Ps by M*Modal
• Test design against samples
Draft H&P
Ballot results
• 78 comments received
– ACP, Trinity Health, Kaiser Permanente,
VHA, Regenstreif
– Epic, GE, Medquist, Northrop
• All comments addressed
– All negatives will be withdrawn
– Draft in revision
– Will re-ballot in August/September
• If passed, will be “Draft Standard for Trial
Use” (DSTU)
– stable platform for implementation
– within 2 years either normative or revised
Ballot issues
• Most difficult
– balance diversity of current practice against
desire for consistency
– where can you lead the industry, where must
you follow?
• Clarify intended content
– Past Medical History vs. Surgical History
• Physical exam: diversity of practice
– Define full set of sub-headings
– Allow narrative &/or sub-sections
Consult Note
• Same method as H&P
–
–
–
–
consistent with precedents
large scale analysis of dictated notes
reuse section-level content
review E&M guidelines
• Examine required metadata
• Examine report contents
– Require “reason for referral”
– Relationship with “reason for visit”, “chief
complaint”
• Seeking pre-ballot review
Future work
• Horizontal: additional document types
– Op note
– Specialize the History & Physical
• Vertical: supporting implementation
– Quick Start Guides for implementers
– Training for implementers
• Promotion: Among providers
– Education on utility, strategic value
– End-user training for compliance
• Whatever it takes to support and promote
widespread adoption
How can PEHRC, PEHRC
members get involved?
• Participate in design review
– through CDA4CDT
– through HL7 Structured Documents TC
– through HL7 Board of Directors
• Participate in the ballot
– as HL7 member or non-member
• Encourage implementation
– within professional society
– within practice group
