The Standard

Q&A With Bryn Lewis, PhD

First Place Winner of the HL7 C-CDA® Rendering Tool Challenge

On Tuesday, September 12, HL7 announced the winners of the HL7 Consolidated Clinical Document Architecture (C-CDA®) Rendering Tool Challenge. 

Bryn Lewis, PhD, a principal software development consultant at Intelsoft in Melbourne, Australia, developed the award-winning tool, Intelsoft C-CDA Viewer. Dr. Lewis's tool is an easy-to-use viewer of complex C-CDA documents available in any web browser.

C-CDA® Rendering Tool Challenge Background

Many clinicians are frustrated with the usability of C-CDA documents. Currently, an overabundance of data is rendered and sent to providers, requiring them to spend time sorting through data that is not relevant to their immediate needs.

HL7 and the Office of the National Coordinator for Health Information Technology (ONC) addressed this need by issuing a tool challenge to develop a viewer to enable clinicians to select the C-CDA document data most clinically relevant to them and display such data in an order they prefer.

The tool was required to meet the following criteria:

• Render the data as specified by the clinician thereby allowing him/her to quickly review the current health and needs of the patient
• Present requested data quickly and clearly through section-based view preferences (ordering), filter functions, intelligent sorting or some other functionality

Dr. Lewis was kind enough to share answers to the following questions ... 

HL7 FHIR: A Standard You Can Use Today! 

A Recap of the HL7 FHIR Applications Roundtable

“A standard is not used because we created it. It is a standard because people use it.”

This familiar quote from Charles Jaffe, MD, PhD, CEO of HL7, could have been the motto for the inaugural FHIR Applications Roundtable held this July at Harvard Medical School in Boston.

As so many of the smiling attendees attested, this was indeed a very different kind of meeting.
The premise was to show how widespread HL7 Fast Healthcare Interoperability Resources (FHIR®) usage already is, and the answer was – more than we could have ever imagined.

The FHIR is spreading

Although FHIR is currently designated as a Standard for Trial Use (STU), it has already captivated the development community who is drawn to its advanced, elegant technology platform. The roundtable, like most FHIR events, cements the impression that interoperability through FHIR is not a pipe dream, but a burgeoning reality.

What is the role of HL7 standards in the eHealth Digital Services Infrastructure (eHDSI)?

eHDSI calls for EU-wide specifications and national extensions or localizations. Interoperability assets and shared terminology resources supporting HL7 standards adoption are needed to streamline large scale eHealth deployment at a reasonable time and cost.

The eStandards project, led by the HL7 Foundation, aims to create a roadmap for collaborative eStandards development fit for the purpose of large scale eHealth deployment. CEN/TC251 and IHE Europe participate in the eStandards project along with key eHealth stakeholders in Europe.

In view of these developments, it is worth reflection on:

• How should HL7 standards be promoted at the national and European level?
• What kind of tools and resources can HL7 offer to support its European members?
• What synergies does HL7 need to engage in Europe?

HL7 as an International Organization

The whole idea of regional offices for HL7 goes back to Ed Hammond’s third HL7 chairmanship in 2008-2009, inspired by the vision to turn HL7 into a truly international organization. This began with changing the organization’s name from Health Level Seven, Inc to Health Level Seven International.

It was not the first time that HL7 Europe came up in discussions. In the 1990’s, the European HL7 affiliates abandoned the idea thinking there wasn’t enough common ground: HL7 was the place for global standards development and localization was national business: France, Italy, and Germany had as much in common as with Australia, Canada, and Japan.
