ASTM/HL7 CCD Release 1


Continuity of Care Document (CCD) Release 1 is intended as an alternate implementation to ASTM ADJE2369 of ASTM CCR (ASTM E2369-05) for sharing patient summary data using HL7 CDA R2 (ISO 27932:2009).

CCD is a collaborative effort of HL7 International and ASTM which combines the benefits of ASTM's Continuity of Care Record (CCR) and the HL7 Clinical Document Architecture Release 2 (CDA) specifications. CCD establishes a rich set of templates representing the typical sections of a summary record and expresses these templates as constraints on CDA.

The ASTM CCR is a core data set of the most relevant administrative, demographic, and clinical information facts about a patient's healthcare, covering one or more healthcare encounters. CCR provides a snapshot in time containing the pertinent clinical, demographic, and administrative data for a specific patient.

The HL7 Clinical Document Architecture (CDA) is a document markup standard that specifies the structure and semantics of clinical documents for the purpose of exchange. From the perspective of CDA, the CCR is a standardized data set that can be used to constrain CDA specifically for summary documents.

CCD uses a detailed set of constraints (or templates) for CDA elements. The templates define how to use CDA elements to communicate clinical data. The scope of the clinical data itself, within the templates, is set by CCR. Each template may have further supporting templates, as required.

One of the most important characteristics of a CCD is that it must be human-readable using any standard Web browser. The patient data within a CCD document is encoded using XML, which can be displayed on a Web browser using a style sheet.

With CCD being a type of CDA document, its primary purpose is for exchange - specifically in the content of a patient being transferred from one care setting to another thus improving patient care.

Using CCD effectively is a move towards more modern communication methods for patient data exchange which ensures following advantages:
