The CDA Management Group (CMG) aims to use the next C-CDA Implementation-A-Thon (IAT) to expand outreach to engage new communities and increase the impact of this content improvement effort. “We learned so much last year about how to maximize the value of implementer-led implementation-a-thons,” said CMG Co-Chair Lisa Nelson. “The new approach was a step in the right direction. It helped implementers drive the conversation and focus the community on making changes that would yield valuable improvements,” she explained.

While HL7 FHIR® (Fast Healthcare Interoperability Resources) is today’s hottest healthcare standard, clinical documents are already exchanged in the billions today. HL7 published the Consolidated Clinical Document Architecture (C-CDA) in 2011 to support care coordination and patient engagement. The ONC 2014 certification rule named C-CDA R1.1 and adoption exploded. The current version of C-CDA, R2.1, remains backwards compatible to that version today. While C-CDA is a flexible, robust standard to record patient care longitudinally or for an encounter, it is structurally complex. The C-CDA standard itself is over 1,000 pages long. Applying the standard to the latest US requirements for clinical data exchange, known as the US Core Data for Interoperability, also routinely requires information from the C-CDA Companion Guide.
HL7 publishes the C-CDA standard and its Companion Guide as PDF documents. That will remain the official version of the standard, but a small team from the CDA Management and Structured Documents Working Groups saw an opportunity to make the C-CDA content easier to use by developing a new web tool. Since the C-CDA has reusable parts, known as “templates,” it seemed logical to make each template searchable and distinct via unique web pages so the standard would be much easier to absorb.
The new HL7 C-CDA Online Search Tool is a searchable, web-based navigation resource for the Consolidated Clinical Document Architecture (C-CDA 2.1) and its Companion Guide. The solution includes over 240 unique web pages that make each template accessible on the web with linkage back to the original PDF content. This navigation is managed through a single searchable index page, like a smart table of contents.
Using the template webpages, health IT vendors can ensure that their C-CDAs are conformant and high-quality for document exchange. The search tool enables users to search the C-CDA by description, template object identifier (OID) or conformance number. Conformance number searches are particularly valuable for C-CDA implementers, since validators will return these numbers when there’s a violation or warning associated with C-CDA testing.
The next Consolidated Clinical Document Architecture (C-CDA) Implementation-A-Thon (IAT) is scheduled this September 14-15 in Atlanta, Georgia. It will be held as a track within the HL7 FHIR Connectathon, allowing attendees to optimize participation across CDA and FHIR-related tracks.
Did you know HL7 offers certification and proficiency exams for its healthcare information technology standards?
Our ongoing tooling journey at HL7 continues, neither as a sprint nor a marathon. For us, it’s really more like an odyssey – an ongoing journey where there is always something more to be done, another path to explore, and a final destination (retirement, for example) seems far out of reach. In the case of HL7 tooling, a fair number of tooling retirements are well overdue.
Despite the wait, it’s gratifying to see when tangible progress is actually achieved. On the Confluence front, we’re in the home stretch of phase 1 of the rollout, though there’s a whole new course to pursue just around the bend. We now have all work groups on Confluence (!) and have also migrated many more projects, committees and collaborations. New functions and help features in Confluence (including a major facelift for confluence.hl7.org) are being added regularly, and you can keep up with these by checking the CTO Tooling Update page. This enabling platform is already unleashing many new opportunities within the HL7 community. Our next target is to work toward optimizing our processes with online forms and workflow. The online project scope statement (PSS) pilot is now available and will give us an opportunity to speed up reviews and approvals as well as make new projects more visible to the community in the hope we can avoid last minute catchups.
Are you HL7 certified?
HL7 offers certification in its primary standards for health information technology including Version 2 (V2), Version 3 (V3), Clinical Document Architecture (CDA®) and HL7 Fast Healthcare Interoperability Resources (FHIR®). The testing is designed to help professionals achieve industry-recognized levels of proficiency and expertise.
A Little About HL7
Small but Mighty
HL7 Austria's annual assembly has become an insider’s guide to the eHealth community. This small but mighty event was held on March 15, 2017 at its regular location, the Heuriger, a local winemaker’s tavern, with a record attendance of more than 100 participants. The annual assembly included a a full day of presentations with timley information, education and networking. We also celebrated the 10th anniversary of HL7 Austria.
More than 20 speakers from four countries delivered engaging talks on the importance of standardization and HL7 in the eHealth area. The presentations covered a wide range of topics that demonstrated what goals have already been accomplished and what work still needs to be done to support interoperable electronic health data exchange in the future.
Introducing the HL7 Companion Guide to Consolidated Clinical Document Architecture (C-CDA®) 2.1
On March 3, 2017, Health Level Seven International and the Duteau Design Inc. team of Jean Duteau, Joginder Madra, Helen Stevens, and Lisa Nelson published the Companion Guide to Consolidated Clinical Document Architecture (C-CDA) 2.1. This companion guide is a supplement to HL7's CDA R2 Implementation Guide (IG): C-CDA Templates for Clinical Notes STU Release 2.1.
