  1. Group C – HL7 France • Objective : Definition of CDA implementation guides. • 17 participants • Public entities • DHOS, GIP-CPS, GIP-GMSIH • Primary care sector • 7 participants. • Hospital sector • 4 participants • Shared EHR, Exchange infrastructure providers • 3 participants

  2. « Volet Médical » Project Objectives : Synthesis of essential patient data (allergies, drug treatments,…). It represents a patient clinical synthesis relevant for any Healthcare Professional that will have to treat the patient independently of a specific care plan or a current care workflow. Hence in practice, the CDA-R2 “Volet Médical” will need to be associated with complementary information (maybe another CDA documents) to reflect exchange context (referral between a GP and a specialist, consultation report, pathology orientated baseline …). This project give a first practical field for HL7 France members to develop CDA know-how. Structured data exchange between Primary care applications for essential data References : Formalism Electronic Medical Summary (e-MS): CDA Implementation Guide Care Record Summary (CRS – HL7 US Realm) Medical Consensus made by HL7 France members

  6. CDA R2 – Header • Ongoing localization (Group C HL7 France) • Vocabulary for document type • LOINC codes or alternative French localization vocabulary ? • LOINC codes may fit with “pure” clinical documents, but we will have to manage medico-administrative documents (related with the social insurance system) that are associated with a codification managed by French Administration (cerfa code). • Identifier for Patients, Healthcare Professionals, Hospitals…

  7. CDA R2 – Body • Body : • Different hierarchy of sections than CRS : ex : • CRS : Procedures (History of surgical procedures) • HL7 France : Personal History / Surgical History • Only leaf sections can have medical content (narrative part and/or entries) • Other sections are only used to describe hierarchical structure of leaf sections • Mixture of the “Flat approach” of section of e-MS structure and hierarchical description of the US CRS to enable an interpretation of the meaning of entries independently of the position of a section in the hierarchy. We anticipate that it could be difficult to define a medical summary order that will be accepted by all medical specialties and that significant sections of the Medical Summary may be reused in other document models.

  8. CDA R2 – Body • Section codes : LOINC codes are available for nearly all cases (need few extensions for ex. : • Active episode of care • Personal history … ) • Specification of CDA level 3 for each section (like e-MS canadian project) • Improving significantly alerts and safety of care (interactions, contra-indications …). • Anticipated need for fine confidentiality granularity control (e.g. voluntary termination of pregnancy will need different confidentiality level than diabetes in the personal history section. • Supported by association of ambulatory care suppliers.

  9. Narrative section only <component> <section> <code code="11348-0" codeSystem="2.16.840.1.113883.6.1" codeSystemName="LOINC" displayName="HISTORY OF PAST ILLNESS"/> <title>Antécédents médicaux</title> <text>Le patient a été sujet dans son enfance à de fortes crises d’asthme et a une Méningite bactérienne en 1979 sans séquelles. </text> </section> </component> • If a sending application that is not able to manage level 3 data for a section than only the narrative part should be used. • Instances will be not extracted from the text by receiving systems.
