The Digital Transformation of Pathology

After my article last month, Advance offered me the opportunity to write a web article to compliment their vendor roundtable article.  Below is the article.

The Digital Transformation of Pathology

by Amanda Lowe

When does the future become a reality?

Imagine your digital future. You walk into your office, and on the desk is a computer; your microscope is covered and untouched; on the shelves are books and journals, and nothing is on the floor. Paper and glass do not cover every inch of your office. Gone are the numerous external hard drives filled with countless images. All that remains is you, your knowledge and a computer.

This computer is your diagnostic workstation, customized to you and providing you with resources to improve diagnostic outcomes, advise on treatments and monitor patient response to those treatments. Digital pathology will enable and frame our digital future. However, forging this vision has not been easy, and realization of the vision is a constant work in progress.

History
In the 1990s, the first robotic microscope was controlled over the Internet by Ronald S. Weinstein, MD,1 and the first slide scanner was invented to measure preinvasive cancer by James W. Bacus, MD, and his son Jim V. Bacus Jr.2 At about the same time, Dirk G. Soenksen, founder of Aperio, was imagining a world where microscopists looked at computer monitors rather than microscopes.3 These four inventors established the foundation for our digital future. As visionaries and advocates, they have brought digital pathology to life.

Resistant to Change

Ask around and the consensus is that digital pathology is our future. However, the timeline of when our future becomes a reality is widely debated. The digital pathology industry, pathology organizations and consumer crusaders have worked hard over the past 15 years to educate the market on the benefits of digital pathology, yet they are often met with a fierce resistance to change. The resistance is often driven by fear–not of change but of being changed.

No one pathologist, department or company can be forced to adopt and learn something new. Therefore, we must continue to educate and create an understanding of the tangible advantages, which instills a desire to change. Change is hard, but if we overestimate the importance of pathology’s capabilities today, we will underestimate the significance of what the field could become tomorrow.

Tangible Advantages

Digital pathology can reduce subjectivity, increase diagnostic confidence and ensure diagnoses are reproducible–all important advantages, especially when incidences of misdiagnosis have been publicized lately and the practice of pathology and laboratory medicine scrutinized. It is well-known that risk for human error in slide preparation and patient identification is greatly reduced when the histology process is bar coded.

A 2009 publication in the American Journal of Clinical Pathology about the Henry Ford Health System surgical pathology lab highlights a 62% reduction in the overall misidentification case rate.3 Add digital pathology to the picture, and you will enable scanning of glass slides, software (instead of technicians) correlating patient data and whole slide images, and electronic delivery of patient information and slides to the pathologist. Risk of error will continue to drop while powerful tools will support the pathologist throughout the diagnostic process.

Have a difficult case? No problem. The pathologist can simply assign the case or send an e-mail request to a specialized pathologist for a second opinion. This digital consultation process, often described as telepathology, is more secure and eliminates the risk of patient slides being lost or damaged, decreases the turnaround time to hours rather than days and reduces subjectivity while controlling costs. Still want more diagnostic support? Search the digital pathology slide database to review relevant clinical slides, quickly retrieve historical patient data, perform image analysis to obtain quantitative support, or easily set up a tumor board with physicians to illustrate the patient case and create a forum to discuss the next step or design a treatment plan.

All the tangible advantages described above can be done today and are being done, although the process is not perfect. Yet to achieve perfection you must find imperfections and then take time to transform those imperfections for the better.

Transformation

Government demands and consumer expectations are growing for transparency in medicine, improvements in patient safety and identification, electronic medical records and more personalized treatment plans. At the same time, the perception of laboratory medicine and pathology needs to improve, especially given its essential and significant role in patient care.

Digital pathology supports this healthcare evolution and enables the digital transformation of pathology and laboratory medicine. Our transformation is not easy. The process is not perfect, but the benefits are powerful and will outweigh the fears. Do not resist the transformation, embrace it.
