C-CDA® Rendering Tool Challenge
HL7 and the Office of the National Coordinator for Health Information Technology (ONC) are holding a challenge to encourage the development of HL7 tools. Will your team be the one to develop the solution and take home the prize?
1st place $15,000
2nd place $5,000
January 12, 2016 – May 31, 2016
September, 2016 - During HL7's 30th Annual Plenary Meeting in Baltimore, MD
HL7's Consolidated Clinical Document Architecture (C-CDA®) standard is an XML-based document markup standard that specifies the structure and semantics of clinical documents such as Discharge Summaries and Imaging Reports that are exchanged between healthcare providers and patients. One of the six characteristics of a C-CDA document is human readability. The process by which these documents are made human readable is called rendering. One of the requirements of C-CDA is that all relevant clinical content of a C-CDA document shall be present (and thus renderable) in human readable form.
Entries must adhere to the current principles and requirements for rendering a CDA document (as found in the Clinical Document Architecture standard):
- There must be a deterministic way for a recipient of an arbitrary C-CDA document to render the attested content.
- If the C-CDA document has a title it must be rendered.
- If the C-CDA Body is structured, the label of a section, as conveyed in the Section.title component, must be rendered. The absence of the Section.title component signifies an unlabeled section.
- When structured content is derived from narrative, there must be a mechanism to describe the process (e.g. by author, by human coder, by natural language processing algorithm, by specific software) by which machine-processable portions were derived from a block of narrative.
- When narrative is derived from structured content, there must be a mechanism to identify the process by which narrative was generated from structured data.
NOTE: These principles and requirements have led to the current approach, where the material to be rendered is placed into the Section.content and it frequently is not clear where to consistently find narrative.
- Submission must be open source
Submission must meet the minimum certification requirements for viewing C-CDA documents out of a health IT application module as stated in the 2015 Certification Criteria (see page 34 at
- Directly display only the data within a particular section,
- Set a preference for the display order of specific sections, and
- Set the initial quantity of sections to be displayed
- The winning entries will reside on Github and made freely available on the HL7 website for use
- Winners will receive a complimentary registration and be encouraged to attend the HL7 30th Annual Plenary meeting (September 18-23, 2016 in Baltimore, Maryland) where they can demonstrate their tool for attendees.
