Over the last few years, Cincinnati Children’s Hospital Medical Center’s (CCHMC) enterprise imaging strategy has been simmering. After starting with radiology and cardiology, the hospital is preparing to add images from across all ‘ologies and fully bring its enterprise archive to a boil.

It’s been a deliberate process, but Jay Moskovitz, technical specialist and PACS administrator at CCHMC, says that’s because such complicated change takes time to get right. “We’d rather get it right than have it out there and have images going to the wrong place or not accessible.”

The strategy at CCHMC centers on the vendor neutral archive from Merge Healthcare, the iConnect® Enterprise Archive. A Merge PACS™ user since 2010, CCHMC has a long working history with Merge, even before its 2008 PACS purchase.

Moskovitz explains there were several goals the hospital had in mind when launching this process.

True disaster recovery

Prior to going live with the iConnect Enterprise Archive, CCHMC had long-term storage for images, but the storage was limited in terms of serving as a contingency system.

“We really had no redundancy at all for images,” says Moskovitz, explaining that all the studies were online, but saved with lossy compression, not a true disaster recovery process for full-fidelity images.

Now, the hospital has replicated hardware at an off-site disaster recovery data center. The data center has the same hardware configuration as the production environment. “If something happened to one of the redundant nodes, there’s one off-site to take over for it,” says Moskovitz.

Everything on the production enterprise archive is automatically reconciled with the disaster recovery site, offering true business continuance in exceptional situations. The latest version of the Merge PACS offers an integrated mode that communicates exclusively with the enterprise archive for images. Whenever the hospital switches over to the contingency server, the exact full dataset of studies will be replicated.

“What’s cool about the Merge PACS system is that all the statuses or anything you do to the study can be sent from the production PACS out to the contingency PACS,” says Moskovitz.

Leveraging an F5 content switch in front of the PACS, the hospital can easily switch traffic out to the contingency PACS server without the end user even knowing, a handy solution when IT wants to apply monthly security patches.

Beyond radiology

The enterprise archive began in radiology, and within the last year has taken over long-term storage for cardiology too. But CCHMC isn’t stopping there. The hospital is starting to use the archive for point-of-care ultrasound studies from rheumatology and anesthesia, and will look to expand the archive even further as the staff gets a better handle on workflows.

Alex J. Towbin, MD, CCHMC radiologist and the Neil D. Johnson chair of radiology informatics, underscores the importance of an enterprise imaging strategy that allows providers to see all of the images obtained for a patient, no matter where the images originated.

“This means that for the first time, all providers can see what is ailing their patients and apply their specialized knowledge to providing care in a more holistic manner,” says Towbin.

It’s no coincidence that the first step outside of radiology was cardiology. “DICOM is just easier to manage,” says Moskovitz. “There’s a much better workflow structure to DICOM, making sure you have all the right data elements… Our place is very conscious about workflow and what makes sense in integrating with the EMR to make everything work well for the end users.”

Since point-of-care ultrasounds are not order-driven, prior to the enterprise archive, these studies couldn’t be billed for as there was no documentation for the imaging. Now, however, instead of sitting on a local system, the studies are sent to the enterprise archive where the procedure can be documented and billed.

Next ‘ology on the list? CCHMC is in the planning stage to bring in dermatology and other departments using standard photography, such as surgical images. The software and tools are all there, though Moskovitz says the hospital is working closely with Merge to navigate the challenging process.

So far, there have been no major issues integrating with other vendors’ systems, such as cardiology. For non-DICOM images, the hospital is opting for a strategy that leverages a DICOM-wrapper for jpegs and other image formats, thus allowing the PACS viewer to
