Corista, an integrated pathology solutions leader, has received from the USPTO a Patent Grant for the Virtual Slide Stage (VSS). The VSS is an interface device that greatly improves the ergonomic efficiency of digital slide viewing for pathologists. Use of the device should  ease the path to greater adoption of digital pathology platforms, via mitigation of what is now a laborious and physically tiring process when using currently available technology.

Telepathology, the ability to view remote pathology images, and more specifically, the technology to allow this to happen, has been available for more than 50 years. 

In the past several weeks we have all seen or been directly impacted by a worldwide pandemic.

Nearly 1/3 of the world’s population is currently on “lockdown”, “shelter in place”, “stay at home” or other similar orders from local, state and national authorities in respective parts of the world. My parents told me about when the city swimming pools had to be closed over concern of poliomyelitis, but few of us have experienced anything like this before. Epidemiologists and sociologists will have plenty to study for the next decade and break down.

Digital pathology continues to gain momentum and is becoming­ more commonplace in pathology laboratories around the world. The list of compelling reasons to move to a digital pathology platform grows longer every day. A single image of a critical specimen can potentially aid in a patient’s diagnosis, help determine their course of treatment, play a role in research and help educate the next generation of practitioners.

But at its core, moving to a digital pathology platform facilitates the sharing of pathology cases and images among colleagues and teams whose networks are expanding every day.

Yogi Berra, the Hall of Fame New York Yankees catcher has famously said “It's tough to make predictions, especially about the future”.

The Jetsons had us believing that by 2020 we would have instant food, video phones and flying cars. Two out of three isn’t bad. So far. Some innovative folks are working on drone-like vehicles that can sustain human flight. Let’s see what happens this year with that.

Ten years ago, digital pathology was leaving infancy and becoming a toddler, learning to walk and run and read and write and communicate. The notion that slide images could be viewed from anywhere, anytime, was still a novel idea, not so much from a technological perspective, but rather from a professional one.

Pathologists have long consulted with their colleagues on difficult cases, and today, with their decreasing numbers and the increase in cancer cases world-wide, the ability to collaborate with colleagues at an international level is key to ensuring patients have access to the best diagnostic expertise available no matter where they are located.

Many large medical centers offer pathology consultation services throughout the US and international communities. In addition to formal consult cases, many pathologists share insights with their colleagues in remote locations, benefitting patients as well as the pathologists who learn from each other in these collaborations.

The key to unlocking the broad benefits of digital pathology, including more efficient use of resources, easy access to colleagues & experts, faster clinical workflows — depends on having an image management system providing broad access to every image in the repository for users to view and share.

Access to healthcare services is in the midst of a fundamental change. Independent community hospitals and academic health centers are consolidating into larger networks across the nation. Furthermore, these networks are also developing global affiliations and partnerships to increase access to diagnostic care worldwide. As a result, patient point-of-service, laboratory services and the professional review of a case may exist in independent locations, sometimes spread over large geographic distances. Pathology department transformations embody this shift.

Multidisciplinary Tumor Boards (MTBs) are a standard of practice in all academic medical centers. Studies show that they contribute to improved diagnoses and treatment plans and often lead to improved patient outcomes.¹ Moreover, these conferences provide valuable real-life education and training to residents and fellows in all represented disciplines.

Historically, pathologists have encountered unique challenges when participating in MTBs. Even with access to digital images for their presentations, the images are often time consuming to attain and in a static image format. Navigation to other regions of interest within the slide is often not possible, and the patient’s case data is usually in a separate lab information system (LIS). Assembling the case, often in Powerpoint, is time consuming, limiting and frustrating.

The microscope has been around for hundreds of years and has reached a plateau of efficiency. Certainly, in my own practice over the last 40 years, the physical process of microscopy has not changed. I still use today the microscope I bought as a resident. Sure, some advances have been made, like tilting heads and automatic turret changes, but these are designed to prevent chronic issues, such as neck and back pain and carpal tunnel syndrome, respectively. They have little to do with the daily efficiency of the process.
