HL7 C-CDA Rendering Tool Challenge (competition from HL7)
HL7 and the Office of the National Coordinator for Health Information Technology (ONC) are organizing a competition to develop tools for viewing HL7 CDA documents. Developments can be sent before May 31, 2016.
The requirements for such a viewer or viewer are rather vague and require not only knowledge of the CDA structure, but also typical problems that doctors encounter when working with them (CSS-based conversion is built into CDA by default).
Prizes

Problem
The XML-based HL7 Consolidated Clinical Document Architecture or (C-CDA) standard defines the structure and semantics of clinical documents such as Discharge Summaries or Imaging Reports (original names are retained hereinafter, as the competition is primarily for the English-speaking audience ) According to the CDA standard, a document must have the following characteristics: Persistence, Stewardship, Potential for authentication, Context, Wholeness and Human readability. The organized contest is aimed at improving the latest characteristics, namely, the readability of the CDA document for the doctor or patient. The process by which XML documents are converted to human-readable in HL7 is called, as expected, rendering. So, one of the requirements for C-CDA is that all clinically important constituent parts of the C-CDA document must be present (i.e.
Currently, many medical practitioners are disappointed with the usability of C-CDA documents due to the overabundance of data provided by EHR systems, which makes it very difficult to sort data by relevance, find relationships between different sections of the document and determine the only event for which C- A CDA document has been created. EHR system providers, for a variety of reasons, usually translate much more information into a human-readable format than practitioners need. In some particularly advanced cases, the patient’s entire medical history is placed in the CDA. Viewer, which is able to simplify viewing only relevant information, will save a lot of time and at the same time ensures that clinicians do not miss the information necessary for making a decision.
The essence of the competition
Participants in the C-CDA Rendering Tool Challenge should develop a viewer to help doctors convert the C-CDA document and provide information relevant only to that doctor. Accordingly, the viewer should convert and display only those data that the doctor considered significant, as a result of which the doctor will be able to quickly and efficiently assess the patient's condition. Viewer should be easy to use, provide the requested data in a short period of time, be it sorted, filtered, or in some other way requested sections of the document.
The developers of such a viewer can implement additional functions, for example, provide not only the data requested by the doctor, but also provide a way to provide duplicate data in different sections.
Requirements
Participants must adhere to existing principles and requirements for converting CDA documents (according to the standard):
• a strictly defined method for converting an arbitrary C-CDA document.
• if a title is defined for a C-CDA document, it must be converted.
• if the C-CDA Body is structured, the section labels defined in Section.title must be converted. The absence of Section.title means the absence of a section of the document.
• if structured content is taken from narrative, a transformation mechanism should be described.
• if content is taken from structured content, there should be a mechanism to determine the process by which narrative was created based on structured data.
Additional requirements:
• development should be open source;
• development should meet the minimum certification requirements for C-CDA document viewers according to 2015 Certification Criteria:
◦ show data only in a specific section,
◦ the ability to sort sections,
◦ the ability to specify the number of sections to view.
• Winner development will be available on Github and can be freely used on the HL7 website.
• Winners will receive free registration and the opportunity to participate in the 30th annual HL7 plenary meeting (September 18-23, 2016 in Baltimore, Maryland), where they will be able to demonstrate their developments.

Update 1 : HL7 hosts a webinar on February 4 / 1:00 - 2:00 PM ET to discuss emerging issues. Registration in the webinar on the competition page.
Update 2 : And so, the competition is completed and the winner is revealed. The winner was Bryn Lewis, PhD, Principal
Software Development Consultant at Intelsoft (Melbourne, Australia). Below, without any translation, the description and links to the C-CDA Viewer Tool from the winner.
The Intelsoft C-CDA Viewer is an easy-to-use viewer of complex C-CDA documents, available directly in any web browser. A responsive document layout automatically adjusts to make optimum use of the available screen space. Users can hide, collapse and move any section of a CDA document.
Additionally:
• Document sections can be manipulated directly via button clicks, drag and drop or via a document Table of Contents;
• All user preferences are saved and automatically applied to subsequent CDA documents opened;
• Ability to detect and hide / show duplicates;
• The result is an intuitive and user-friendly document layout that users can directly control;
• The tool runs in any modern browser and can be used on a PC, tablet or mobile device. It will also run as a standalone local fileset.
