SOA Expressway Provides IHE On-Ramp at HIMSS Interoperability Showcase

In a previous post, I stated that Intel&aposs SOA Expressway for Healthcare (Expressway) passed IHE Connectathon testing. This was accomplished by constructing workflows that encapsulate the requirements (transformations, transactions, etc.) necessary for various IHE profiles. These IHE Workflows, now packaged within Expressway, provide an IHE on-ramp/off-ramp for applications and systems either lacking or needing additional infrastructure to accommodate IHE interoperability. At the HIMSS Annual Conference and Exhibition held April 2009 in Chicago, Expressway did just that – providing the key infrastructure "bridge" for the following IHE Profiles:

Each year, the IHE Interoperability Showcase provides the opportunity to view actual demonstrations of IHE interoperability as applied to real-world healthcare scenarios. One of those scenarios demonstrated the sharing of encounter summaries and related documents across the network of affiliated healthcare providers (participants in the showcase) via the IHE XDS profile. However, the registration system used lacked the native infrastructure to share documents with the XDS domain. By simply directing their HL7 v2.3.1 feed to Expressway, XDS Medical Summaries (HL7 v3 CDA R2 / CCD documents) were created and submitted to the local document repository. Expressway was able to easily accomplish this by:

  1. Utilizing it&aposs large mapping libraries (HL7v2.x to HL7 v3 CDA) to convert the native HL7 v2.3.1 feed to the XDS Medical Summary.
  2. Utilizing the IHE Patient Identity Workflow (PIX/PDQ) to augment the Medical Summary with a patient ID recognized by the XDS domain.
  3. Sending the augmented Medical Summary to the IHE XDS workflow, which securely sent the document to the XDS repository over TLS.
  4. Additionally, the IHE ATNA workflow was able to provide audit information of key steps to an audit server.

Other healthcare scenarios during the Showcase focused on radiology. One participant in this scenario was Sorna and their Reviewer product, which is used to transfer radiological exams to portable media. However, in order to create XDM compliant media, additional content, specifically, diagnostic reports (HL7v3 CDA compliant document) and metadata about the reports (XML document) were needed. Other participant&aposs systems in the radiology demonstrations could generate diagnostic report content, but lacked capability to produce it in a format compliant with the XDM profile. One of those was TSG&aposs iView, application, which generates diagnostic reports but only in PDF format. Another was Philips XIRIS 7.3 product, which was also able to encapsulate their reports but using HL7. Expressway was again able to provide the necessary infrastructure by accepting these reports, parsing them, and creating the appropriate XDS documents which were then forwarded Sorna, simply by utilizing native adapters, translation maps, and IHE components inside Expressway.

Intel SOA Expressway for Healthcare is a high-performance health information gateway from Intel, that simplifies healthcare information interoperability. It provides a configuration-centric solution to integrate islands of health data and ensure data privacy, delivers out-of-the box support for healthcare data standards, and enables healthcare organizations to service-enable their legacy Healthcare IT to interoperate with the entire healthcare enterprise. IntelĀ® SOA Expressway for Healthcare is a specific implementation of a new product category called a SOA "soft appliance", which delivers a breakthrough in simplicity, cost and scalability for enabling high-quality health information exchange.
