The HL7 Clinical Document Architecture
• 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

Why ?• Lack of usable and re-usable
electronic data: Numbers moving slowly upward, if at all
• Need to get information to the point of care, as-needed, when needed
• Need to leverage investment in information through re-use for decision support, claims, clinical trials…

Applications of the CDA…or
What can you dowith a few tags?
• access/portability/exchange– query/locate by patient, provider, practioner,
setting, encounter, date– access distributed information through
common metadata
• integration– multiple transcription systems– with EHR records
• re-use/derivative data– summaries, reports– decision support

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.”

Other Key Aspects of CDA
• CDA documents are encoded in XML• CDA documents derive their meaning
from the HL7 Reference Information Model (RIM) and use the HL7 Version 3 data types
• The CDA specification is generic to all clinical content
• CDA documents can be constrained to meet the requirements of specific document types
![Page 18: Copyright 2004 Liora Alschuler Clinical Document Architecture CDA::CCR and the Continuity of Care Record MRI Conference August 2004, Boston Liora Alschuler](https://reader036.vdocument.in/reader036/viewer/2022062511/5514d687550346b0338b536e/html5/thumbnails/18.jpg)

• CDA documents are “human readable” =– This principle means that CDA documents
are human readable using: a) widely-available and commonly deployed
XML-aware 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

The CDA Header: Purpose
• The CDA Header is constant across all CDA documents. Its purpose is to:– Enable clinical document exchange
across and within institutions– Facilitate clinical document management– Facilitate compilation of an individual
patient’s clinical documents into a lifetime electronic patient record(“uniquely identify a single patient”)

Code Display Name Definition ADMPHYS admitting physician A physician who admitted a patient to a hospital or other care unit that is the context of this
service. ANEST anesthesist In a typical anesthesia setting an anesthesiologist or anesthesia resident in charge of the
anesthesia and life support, but only a witness to the surgical procedure itself. To clarify responsibilities anesthesia should always be represented as a separate service related to the surgery.
ANRS anesthesia nurse In a typical anesthesia setting the nurse principally assisting the anesthesiologist during the critical periods.
ATTPHYS attending physician A physician who is primarily responsible for a patient during the hospitalization, which is the context of the service.
DISPHYS discharging physician A physician who discharged a patient from a hospital or other care unit that is the context of this service.
FASST first assistant surgeon In a typical surgery setting the assistant facing the primary surgeon. The first assistant performs parts of the operation and assists in others (e.g., incision, approach, electrocoutering, ligatures, sutures.)
MDWF midwife A person (usually female) helping a woman deliver a baby. Responsibilities vary locally, ranging from a mere optional assistant to a full required participant, responsible for (normal) births and pre- and post-natal care for both mother and baby.
NASST nurse assistant In a typical surgery setting the non-sterile nurse handles material supply from the stock, forwards specimen to pathology, and helps with other non-sterile tasks (e.g., phone calls, etc.)
PCP primary care physician The healthcare provider that holds primary responsibility for the overall care of a patient. PRISURG primary surgeon In a typical surgery setting the primary performing surgeon. RNDPHYS rounding physician A physician who made rounds on a patient in a hospital or other care center. SASST second assistant surgeon In a typical surgery setting the assistant who primarily holds the hooks. SNRS scrub nurse In a typical surgery setting the nurse in charge of the instrumentation. TASST third assistant In a typical surgery setting there is rarely a third assistant (e.g., in some Hip operations the third
assistant postures the affected leg.)

Low End Applications for CDA
• Persistant, accessible, human-readable documents
• Requirements:– CDA header– Release One or Two body
• Narrative block• Non-semantic markup (HTML-like)
• Options:– More complex markup can be inserted, to
be used or ignored

What you can do with simple CDA documents: the registry
hub
“what imaging reports are available from the last episode?”1. Create documents 2. Register 3. Discover
4. Retrieve
• Ubiquitous access to distributed information– By class of document, patient, provider, encounter (CDA
header metadata)– Documents remain under local control– Document creation technology evolves under local control– Registry (hub) for access control, identifier xRef

CDA: Return on Investment
– Low end: Access to documents• “please send referral letter to…”• “please get me the discharge summary…”• “what imaging reports are available from the
last episode?”
– High end: Reuse• Send synopsis to tumor board• Attach to claim for automated adjudication of
payment• Extract data for clinical research

Why do we need a CDA?A document specification that hits the 80/20 sweet spot:
Jim Klein, Gartner Group, on HL7’s CDA, April, 2001 RU:
“HL7's Clinical Document Architecture (CDA) defines a new target for clinical information exchange that is substantially easier to hit than one based on standards for discrete data while delivering 80 percent of the value of the latter approach.”

ASTM/HL7 MOU• “ASTM has just adopted a standard set
of core data elements for a Continuity of Care Record (CCR) and is in the process of developing an implementation guide for same, and HL7 has adopted a standard for Clinical Document Architecture (CDA) and a standard for the functionality of an Electronic Health Record (EHR) system. Since both SDOs want implementations based on these standards to be semantically interoperable, we agree to cooperate in the process of harmonizing the definitions of the data elements and the methods for representing instances of the data elements in XML….
