CDA : Clinical Document Architecture • CDA is an international standard • ANSI/HL7 CDA R1.0-2000 • ANSI/HL7 CDA R2.0-2005 • CDA is an XML-based format for clinical document
Interoperability • CDA proposes two levels of interoperability • Human • CDA describes traditional structure of a document • CDA does not required sophisticated tools to be “directly” read by Healthcare professionals or patients • Application interoperability • multimedia content • data
Characteristic of a CDA document • Persistence • Stewardship • Potential for authentication • Context • Wholeness • Human readability • A CDA document is a defined and complete information object that can include text, images, sounds, and other multimedia content.

CDA R1 First HL7 standard based on the RIM Header Body Body : some structured clinical data for automatic processing
CDA Header • Document Identification (ID, code, title, date …) • Confidentiality, language, authorisations • Authenticator(s), including legal authenticator • recipient(s) du contenu • Author(s), Data enterer • Patient • Informants • Related Document(s) • Service Event(s), Participant(s), Encounter

Benefits of CDA R2 • Non limited Vocabularies (SNOMED, LOINC, national vocabularies…) • Structured data coherent with the HL7 RIM • Modification of Confidentiality code, language, auteurs, within a section • Internal and external links • An observation (eczema) a substance administration (penicillin) • An observation (fracture) une image (radiology) • Current document (Discharge letter) another document (referral) • A unique schema an a generic XSL stylesheet
For all type of documents Communication Admission evaluation Transfer of care referral Pre-operative evaluation and management Evaluation and management Subsequent evaluation Conference Summarization of episode Case conference Transfer summarization Consult Discharge summarization Confirmatory consultation Summary of death Counseling Transfer of care referral Group counseling Supervisory direction Education Telephone encounter History and Physical Interventional Procedure Admission history and physical Operative Comprehensive history and physical Pathology Procedure Targeted history and physical Autopsy Initial evaluation Admission evaluation Admission evaluation Pre-operative evaluation and management
CDA Implementation guides • The objective is to give a common “table of contents” to all document of a specific type • Additional constraints to the generic CDA standard • First initiatives for CDA medical summaries • e-MS (British Columbia) • Clinical Record Summary (HL7/ASTM – US)
Important development • International • Germany SCIPHOX (medical summary) • Finland (~ 100 CDA guidelines) • France Volet Médical (medical summary) • New Zeland Health Information Summaries • Italy TeleMed Escape • UK (NHS, South Staffordshire) • Japan MERIT-9 • Greece HYGEIAnet/WebOnColl • … • IHE • IHE “Transactions profiles” are extended by IHE “integration content profile”

IHE-XDS • Cross Document Sharing integration profile • Neutral from format • RTF, PDF, DICOM, JPEG… and CDA • Neutral from type of CDA document • Metadata used for management of the document inherits from the CDA header
IHE-XDS – Actors/Transactions • Extension of Clinical Content Profile also with XDM and XDR integration profiles
XDS-MS • 2006 : PCC a new IHE domain PCC (Patient Care Coordination) • First focus : To leverage IHE-XDS for Medical Summary Documents • A class of clinical documents that contain the most relevant portions of information about the patient intended for a specific provider or a broad range of potential providers in different settings. • Content Profiles define how the content used in a transaction is structured. • Implementation guides for types of CDA document
Extension to other IHE domains • Laboratory domain : Example of a use case from the 2007 Sharing Laboratory Reports (XD - LAB)
LAB CDA report constraints • A clinical laboratory report SHALL have a structuredBody. • This body is organized as a tree of up to two levels of sections. • Top level sections represent laboratory specialties. • … • …

Conclusion • CDA R2 a flexible tool to manage electronic document • Ready to use • Implementation guides to constraint CDA document types • New localisation possibilities for national IHE • Rapid development • International initiatives outside IHE context • IHE Content profiles
