Intelsoft developer Bryn Lewis wins HL7 CDA rendering tool challenge

Australian software developer Bryn Lewis has won an international challenge set by HL7 International to make the rendering of consolidated clinical document architecture (C-CDA) documents easier for clinicians.

Dr Lewis, who works with Melbourne-based healthcare software development firm Intelsoft, which makes a web-based clinical audit data analysis system called WebQI, put forward the open source Intelsoft C-CDA Viewer, an easy-to-use viewer of complex C-CDA documents that is available in any web browser.

Dr Lewis, who is also a consultant with Australian Healthcare Associates (AHA), has tested his viewer in Firefox, Chrome, IE and Safari, and it can be used on mobile devices. He has won $15,000 and an invitation to attend HL7’s 30th annual plenary in Baltimore in the US next week.

According to HL7, the idea for the challenge arose from the recognition that clinicians are frustrated with the usability of C-CDA documents, which sees an overabundance of data rendered and sent to providers, requiring them to sort through data that is not relevant to their immediate needs.

CDA is a document exchange standard for healthcare in which documents are encoded in extensible markup language (XML). It forms the basis for Australia's My Health Record (MyHR) system.

C-CDA is an implementation guide which specifies a library of templates and prescribes their use for a set of specific document types, such as a care plan, discharge summary or progress note.

HL7 and the US Office of the National Coordinator for Health Information Technology (ONC) have tried to address the difficulty of using C-CDA by issuing a tool challenge to develop a viewer that could enable clinicians to select the C-CDA document data most clinically relevant to them and display it in an order they prefer.

Dr Lewis has posted a quick five-minute demonstration of his viewer on YouTube and made the software code and documentation available at GitHub.
