However, implementing these complex digital ecosystems requires a delicate balance between forward-looking scalability and immediate, everyday clinical utility.
This tension lies at the heart of a highly anticipated industry event hosted by CAP TODAY. Originally scheduled to showcase the pioneering work of the Ohio State University (OSU) Wexner Medical Center’s Department of Pathology, the webinar titled "Learn about digital pathology technology that is future-ready, yet practical for today’s laboratory needs" has been postponed to a future date.
The delay of this high-profile panel—featuring senior systems consultants, imaging technologists, operational directors, and moderated by CAP TODAY publisher Bob McGonnagle—highlights a broader industry truth: the path to digital transformation is complex, highly dynamic, and demands deep alignment across clinical, technical, and administrative disciplines.
As laboratories worldwide prepare for the rescheduled session, this investigative report explores the operational blueprints, technical infrastructure, and strategic decisions that define modern digital pathology. By analyzing the work of the OSU Wexner Medical Center, we examine how leading institutions are successfully bridging the gap between cutting-edge innovation and practical, day-to-day laboratory medicine.
Detailed Chronology: The Evolution of Digital Pathology at Wexner Medical Center
The journey toward full clinical digital pathology validation is not an overnight transition, but rather a multi-year, highly regulated evolution. To understand the context of the upcoming webinar, it is essential to trace how academic medical centers like the OSU Wexner Medical Center constructed their digital pathology infrastructure.
[Phase 1: Research & Piloting] ──> [Phase 2: Regulatory Validation] ──> [Phase 3: Enterprise Scale]
- Remote consultations - FDA clearance pathways - High-throughput scanning
- High-resolution archiving - CAP/CLIA validation protocols - AI-assisted triage & LISPhase 1: Research, Education, and the Early Adopter Era (Pre-2017)
Prior to the widespread clinical adoption of Whole Slide Imaging (WSI), digital pathology at academic hubs was primarily confined to research, education, and tumor board presentations. Early scanners were slow, storage costs were prohibitively high, and software interfaces lacked the intuitive speed required for high-volume diagnostic workflows.
During this phase, pioneering institutions laid the groundwork by establishing dedicated digital imaging laboratories. Technologists began standardizing slide preparation, realizing that digital scanners are far less forgiving of tissue folds, air bubbles, and variable staining than the human eye.
Phase 2: Regulatory Breakthroughs and Clinical Validation (2017–2020)
The regulatory landscape shifted dramatically in April 2017 when the U.S. Food and Drug Administration (FDA) granted marketing clearance to the first WSI system for primary diagnostic use. This milestone transformed digital pathology from an educational novelty into a legitimate clinical tool.
Institutions like the Wexner Medical Center began the rigorous process of clinical validation. Under College of American Pathologists (CAP) guidelines, laboratories were required to perform extensive validation studies—comparing digital diagnoses against traditional glass slide diagnoses across hundreds of cases—to ensure diagnostic concordance and patient safety.
Phase 3: Pandemic Acceleration and Enterprise-Scale Integration (2020–Present)
The COVID-19 pandemic acted as an unprecedented catalyst. In response to social distancing requirements and remote work mandates, the FDA temporarily relaxed enforcement policies, allowing pathologists to review and sign out cases remotely using validated digital systems.
This shift accelerated the operationalization of digital pathology. It was during this period that the roles of system consultants, imaging technologists, and operational directors converged to scale up these platforms. What began as a tool for remote consultations quickly evolved into a centralized, high-throughput diagnostic engine capable of handling hundreds of thousands of slides annually.
Supporting Context & Metrics: The Mechanics of Modern Digital Pathology
To appreciate the insights of the Wexner Medical Center panel, one must understand the immense technical and operational metrics that govern digital pathology systems. Designing a system that is "future-ready, yet practical" requires solving a massive data and workflow puzzle.
The Big Data Challenge: Storage and Bandwidth Infrastructure
Unlike radiology, where imaging files are relatively compact, a single digitized pathology slide is an incredibly dense data file.
- Slide Resolution: Captured at 20x or 40x magnification, a single WSI file can range from 1.5 gigabytes (GB) to over 3 gigabytes (GB) in size.
- Daily Volume: A high-throughput academic laboratory processing 1,500 slides per day generates approximately 2.25 to 4.5 terabytes (TB) of raw data daily.
- Annual Storage Requirements: On an annual basis, this translates to over 1 petabyte (PB) of storage, factoring in redundant backups and metadata.
+---------------------------------------------------------------------------------+
| DAILY DATA GENERATION PIPELINE |
+---------------------------------------------------------------------------------+
| 1,500 Slides/Day ==> ~2.25 - 4.5 TB/Day ==> ~1.1 PB/Year (with redundancy) |
+---------------------------------------------------------------------------------+Managing this data volume requires a sophisticated, multi-tiered storage strategy. Systems consultants must design infrastructures that utilize "hot" storage (high-speed, expensive solid-state drives) for active cases requiring immediate diagnostic review, and "cold" storage (cloud-based or tape archives) for historical cases that must be preserved for legal and clinical retention periods (often 10 years or more).
Operational Workflow Metrics: Glass vs. Digital
The transition from physical glass slides to digital pixels fundamentally alters laboratory metrics. While the upfront time required to scan and quality-check slides adds a step to the histology laboratory, it yields massive time savings downstream.
| Workflow Metric | Traditional Glass Workflow | Digital Pathology Workflow |
|---|---|---|
| Case Distribution | Manual sorting, physical delivery of slide folders to offices. | Instant, algorithm-based digital routing based on subspecialty. |
| Consultation / Second Opinion | Packaging slides, shipping via courier, multi-day delays. | Instant secure link sharing for real-time remote consultation. |
| Archival Retrieval | Physical retrieval from basement archives (hours to days). | Instant query search within the Laboratory Information System (seconds). |
| Ergonomics & Fatigue | Repetitive neck strain from microscope use. | Ergonomic monitors, customizable viewing software. |
Official Statements & Industry Perspectives
The postponed webinar features a carefully curated panel representing the three pillars of digital pathology success: IT/Systems, Technical Execution, and Operational Strategy. Industry leaders emphasize that the synergy between these roles is what makes a digital program viable.
The IT Perspective: Scott Hammond, Senior Systems Consultant
As a Senior Systems Consultant within the Digital Pathology Division at Wexner Medical Center, Scott Hammond operates at the intersection of clinical pathology and enterprise IT. Hammond has frequently emphasized that interoperability is the key to future-readiness.
"A digital pathology system cannot exist as an island. To be truly practical, it must seamlessly integrate with the Laboratory Information System (LIS) and the broader Electronic Health Record (EHR). Pathologists should not have to jump between multiple software programs to view a slide, read clinical history, and sign out a report. Our goal is to create a unified cockpit for the diagnostician."
The Technical Execution Perspective: Ursula Hofer, Imaging Technologist
Ursula Hofer, working within the Pathology Digital Imaging Lab, represents the front lines of digital quality control. The success of any digital pathology program hinges on the quality of the scan, which in turn depends on the quality of the physical slide.
"The scanner is only as good as the histology. If a slide has uneven cutting, excess mounting medium, or folded tissue, the scanner may fail to focus, resulting in a blurry digital image that requires a rescanning cycle. Our role is to optimize both the physical preparation and the scanning parameters to ensure that the pathologist receives a diagnostic-quality image on the first attempt."
The Operational Perspective: Sandra Banky, PA(ASCP), Director of Operations
For Sandra Banky, Director of Operations, the primary challenge is justifying the capital expenditure and demonstrating a clear Return on Investment (ROI).
"Implementing digital pathology requires a significant upfront investment in scanners, storage, and software licenses. To make this practical for today’s laboratories, we must demonstrate tangible operational efficiencies. This includes reduced turnaround times for cancer diagnoses, decreased slide-archiving costs, and the ability to recruit and retain top pathology talent by offering flexible, state-of-the-art work environments."
The Moderator’s View: Bob McGonnagle, Publisher of CAP TODAY
As the moderator of the upcoming panel, Bob McGonnagle brings a bird’s-eye view of the entire clinical laboratory industry.
"Laboratories are facing severe workforce shortages, both in histotechnologists and board-certified pathologists. Digital pathology is no longer just a cool technological toy; it is a critical tool for workload balancing. It allows an institution to distribute its clinical volume across a network of pathologists, regardless of where they are physically located, maximizing efficiency and improving patient care."

The ultimate value of digital pathology lies not just in viewing slides on a screen, but in what can be done with those pixels. Artificial Intelligence (AI) and Machine Learning (ML) algorithms are being developed to act as "co-pilots" for pathologists.
- Triage and Prioritization: AI can pre-screen slides to identify suspected malignancies, sorting them to the top of the pathologist’s queue for immediate review.
- Automated Quantification: Algorithms can precisely calculate Ki-67 proliferation indexes, HER2/neu staining intensity, and PD-L1 expression, reducing inter-observer variability and improving precision medicine.
2. Remote Diagnostics and Democratized Care
Digital pathology is breaking down geographical barriers. Community hospitals and rural clinics that lack specialized subspecialists (such as neuropathologists or dermatopathologists) can instantly transmit slides to academic hubs like the Wexner Medical Center. This democratization of expert diagnostics ensures that patients receive world-class care, regardless of their physical location.
3. Spatial Biology and Multi-Omics
Looking further ahead, digital pathology is merging with genomics and spatial biology. Future-ready platforms will allow clinicians to overlay genetic sequencing data directly onto the digital tissue map, providing a multi-dimensional view of the tumor microenvironment. This integration will be critical for the next generation of oncology therapeutics.
