From the March 2011 issue of HealthCare Business News magazine

Unfortunately, according to research published in the Journal of the American College of Radiology and carried out by Johns Hopkins University, only about 61 percent of respondents said most outside medical images digital media provided by patients were readable or importable.

Today, many EHRs offer access to transcribed reports; but without access to actual images, clinicians can be at a loss. In many situations, doctors need to review current and prior images to draw effective conclusions. Many physicians also want the “quantitative” data provided in an image in addition to the subjective interpretation of a colleague.


Technological advances are fueling the development of solutions to enhance health information exchange infrastructure -- including new approaches for sharing images between providers and comprehensive integration of imaging into broader HIT applications. Using the Internet as a secure transport mechanism, sophisticated review-quality images can be delivered in real-time, thus supporting an efficient patient referral process. Images can be rendered remotely on the fly, eliminating costs associated with image duplication and redundant storage. It is now possible to provide access to any image at any time and to display it on any viewing device.

We are moving into a new era with patients, providers, and payers managing the health care experience from computers, mobile devices and new types of access points such as kiosks. The electronic health record will truly be meaningful if it includes diagnostic images. And health information exchanges will truly live up to their name if diagnostic imaging data can be electronically shared across institutions, geography, systems, and time.

When seeking interoperability and evaluating image exchange solutions, organizations should ask the following:
• Can we add the solution to my existing systems to optimize monies already spent?
• Is the solution modular or componentized, thus allowing us to scale incrementally?
• Does the solution support international interoperability standards?
• Does the solution provide a completely integrated IHE XDS infrastructure suite?
• Does the solution support exchange and rendering of images from one vendor’s system to another? Is the archive truly vendor “neutral” specifically for image management?
• Does it provide connectivity even to users who are globally dispersed, or unable to move to a full XDS infrastructure?
