What is Digital Pathology?

Digital ailment refers to the practice of using digital scanning devices and computer software to capture, manage and interpret images of tissue samples and slides from pathology labs. With digital ailment, microscope slides are scanned at high magnifications, producing high-resolution digital images that can be viewed, managed and analyzed on monitors.

Benefits of Digital ailment

One major benefit of digital ailment is enabling remote collaboration. With digital images, pathologists can consult with colleagues anywhere in the world to get a second opinion on diagnoses. Specialists in rare diseases can provide input without the physical slide needing to be shipped. This allows for more expertise to be brought to bear for difficult cases.

Digital images also enable computer algorithms and artificial intelligence (AI) to assist pathologists. AI and machine learning tools are being developed to help flag areas of interest, detect anomalies, and potentially even make preliminary diagnoses. This could help reduce diagnostic errors and variations between pathologists. Over time, as more data is fed into these systems, their abilities are expected to advance greatly.

Going digital also opens up new possibilities for education and training. High-quality whole slide images can be shared securely with pathology residents and fellows around the world for learning purposes. Trainees don't need physical access to rare specimen types to gain experience in their diagnosis and classification.

Data Management and Efficiency Gains

The Digital Pathology yields significant data management and archiving advantages over physical slides. Digital slides take up much less physical storage space and can be easily accessed from any networked computer. Their images do not degrade over time like glass slides can.

Pathology laboratories also gain efficiencies from digital workflows. Slides only need to be scanned once, after which the digital version can be consulted an unlimited number of number of times without risk of physical damage. This eliminates the need to retrieve, transport and reshuffle actual slides between pathologists. It also enables simultaneous review by multiple parties.

Telepathology and Rapid Consultations

One major application of digital ailment is telepathology - the ability to conduct virtual slide consultations across geographic distances. A primary care physician in a rural hospital can get an urgent second opinion from an academic center hundreds of miles away simply by uploading and sharing a digital ailment case.

This facilitates rapid consultations that may not have been possible if physical slides needed shipping or transport. It allows small practices and hospitals to leverage the expertise of large academic medical centers regardless of location. For surgery, oncology, and timely disease management, speedy access to specialist input is extremely valuable.

Is Whole Slide Imaging Accurate?

One common concern raised about digital ailment is whether whole slide images are of high enough resolution and quality to reliably replace microscopic examination. Several validation studies have demonstrated that digital and glass slide interpretations match at a very high concordance rate, often 98% or higher.

For some tissue types and diagnostic questions, a pathologist may still prefer using a physical microscope. But the image fidelity of today's high-end whole slide scanners is generally considered more than adequate to support the primary diagnostic needs of most pathologists. Continued improvements in scanner technology will only increase this accuracy and usefulness over time.

Impact on Workflow and Adoption Rates

The transition to a digital workflow does require upfront financial investments in scanning equipment and image management systems. It also necessitates adjustment periods as pathologists and lab staff adapt familiar paper-based processes.

For this reason, the adoption of digital ailment solutions has so far been higher in large health systems and academic medical centers that can more easily absorb costs. But as prices of scanners decrease and the benefits become clearer, smaller community hospitals and private practices are bringing digital on board as well.

As younger pathologists already comfortable with screens enter the field, digital is poised to become the new standard model over the next decades. Hybrid solutions combining digital and glass slide review will also allow the staged transition many laboratories need. The future of pathology is undoubtedly becoming a digital one.

Managing Organizational Change

Successful implementation of any new digital system will depend on buy-in from key stakeholders and good change management practices. Areas like data governance, privacy, and cybersecurity also need appropriate policies and safeguards established upfront.

Because digital ailment fundamentally changes traditional work patterns, it is important for laboratories to provide training and support to help pathologists, technologists and other staff adapt. Open communication about the goals and anticipated impacts will help facilitate understanding and cooperation during deployment. Addressing concerns about workflow effects and usability proactively can support smoother adoption.

Digital pathology represents an exciting and beneficial evolution for the specialty. While some challenges remain in modernizing established practices, the technology's advantages in access, collaboration, education and AI-augmentation far outweigh any drawbacks. With judicious planning and user support, pathology departments can transition successfully to digital workflows and realize substantial benefits. The future is digital and now is the time to embark on this important journey.
