It’s been a year and a half since Nuance Communications launched the Nuance PowerShare™ Network. It did so by acquiring the cloud-based medical image sharing company Accelarad and expanding its platform into a powerful web-based exchange for combined images and reports.

What a year and a half it’s been. Today, PowerShare Network connects more than 2,700 healthcare provider sites and has facilitated the exchange of medical images to the tune of more than 3 billion. And the count grows every day. 

Meanwhile, this past summer, Nuance was identified as the mindshare and market-share leader among all medical image-sharing suppliers by peer60, a software vendor and industry research company, after it surveyed more than 500 healthcare organizations.

The peer60 report called PowerShare Network performance “an impressive feat.” The compliment was made all the more meaningful by the survey’s finding that nearly 90% of providers consider receiving medical images from other sites “the most important problem to solve” through image sharing.

To get a clearer picture of PowerShare Network beginnings and its future direction, Health Imaging spoke with Helmut Domagalski, the Nuance product director who serves as product manager of both PowerShare and PowerScribe® 360, the popular voice-to-text dictation system designed specifically for radiology.

Instant interconnectedness

The original guiding vision behind PowerShare Network — which Nuance had been working on for several years prior to the Accelarad acquisition — contains three main components.

First, the network had to allow the movement of images across “disparate islands” while working to cut CDs out of the picture.

“If you think about it, as you look at any region of care, even EMRs, VNAs and PACSs are islands,” Domagalski observes. “How can we cut across those barriers quickly? We had several different regions where we’ve been able to connect rapidly, with a very small IT footprint, through our low-footprint IT design and our outreach services.” These include preferred channels, direct messages and automated tools that allow users to immediately act on incoming information.

Second, PowerShare fosters cross-hospital, physician and patient communications in order to help improve patient care while reducing costs on a broad scale.

The PowerShare Network “is built to resemble a social media app, such that hospitals, patients and providers all have their own accounts,” Domagalski says. “The concept was very disruptive of the market norm of CD islands, as it broke away from the traditional EMR/PACS structure and really enabled cross-site, national level collaboration over imaging via the cloud.”

It also made every image associated with every patient available in a single bank regardless of where — or at how many different sites — the images had been captured.

The third and final key piece was only logical. A diagnostic image without an accompanying report is, after all, rather like a silent movie without subtitles.

“Nuance took that original vision and said, ‘Let’s marry reports to images, and then let’s continue to expand the value of that network beyond images and reports,’” Domagalski recalls. “From there we could bring in components for quality and analytics, and we could look at connecting with ACR and other groups.” 

The resulting PowerShare Innovation Program — unveiled at RSNA 2014 and well established today — presents this multi-pronged functionality as a jumping-off point for providers to tap into the power of image-based and/or report-based cloud networking.

“Take surgery for example. We can offer users the choice of working with a surgery vendor or deploying other viewers on our technology so they don’t have to play the ‘viewer game,’” Domagalski explains. “They can choose to put their technology and best diagnostic toolsets on the network.”

The PowerShare Network vision doesn’t call for moving away from image sharing, he stresses. On the contrary, it maintains image sharing “as our core product and expands it outward.”

Innovation station

Not incidentally, the Innovation Program had momentum to build on right from its inception. Massachusetts General Hospital (MGH) signed on to partner with ACR and Nuance, announcing the partnership at the RSNA 2014 unveiling. Since then, MGH has used the program to deliver an initial set of radiology clinical decision-support guidelines to the broader radiology community by integrating the guidelines into the PowerScribe workflow.
