Imagine 1.Cover 3 sites 2.No new staff available 3.Increasing workload
University Health Network • TGH, PMH, TWH • No on-site TWH pathologist • 2-10 frozen sections • per week (mostly • neurosurgery) • Sept. 2004 – no NP X X ~ 1 mile X
UHN S S IMAGINE 2! S Research S= Service
UHN IMAGINE3: 3 Departments of Pathology! # Q S Sites
Right Circumstances Problem!! The Perfect Storm---! Right Tools!! Available! Right Leadership
TWH Frozen Sections: The Problems to Be Solved Single pathologist traveling to TWH Inefficient process - traveling time and waiting Disruptive to regular workflow – 99% of departmental activity occurs at TGH delays in regular sign-out affecting other UHN patients No possibility for consultation on difficult cases – possibly affecting TWH surgical patients. Compromised diagnostic accuracy Unnecessary deferred diagnoses
The Robotic System: November 2004-October 2006 • 350 frozen sections • accurate • deferral rate < 10% • slow (~ 10 minutes/slide)
The Robotic System Toronto Western Toronto General Telepathology Work Station (not a pathologist’s office)
Whole-Slide Imaging: October 2006-Present • > 1800 frozen sections/1500 patients • 90% from neurosurgery • 98.5-100% accuracy (month to month) • 14-16 minute turnaround time • 5% deferral rate • - 2 pathologists review all deferrals
Telepathology Was A Viable Solution • > 90% of the cases are single block • Surgeons select the tissue of interest • no need for gross assessment by pathologist • surgeon-defined margins • submit in toto for frozen section/smear • Robotic microscopy (2004-2006) • most intense development and validation • Transition to WSI (late 2006- present)
Whole-Slide Imaging: Architecture • Easy consultation with colleagues – better for patient care • WSI had essentially no learning curve (compared to robotic microscope) This was TGH/UHN

Volume aging population higher sensitivity for early disease Demand Sophisticated knowledgeable population Culture of “instant gratification” New technologies genomics proteomics informatics robotics ‘tissue soup’ instead of tissue Challenges for 2020 MONEY?? 18
The Challenge for 2020 • Faster • Better • Higher quality • Personalized • Cheaper • Innovative
The New Paradigm: Faster Pathology must be faster “Same Day” diagnosis Automation 24/7 labs Faster
The New Paradigm: Faster Speech-recognition integrated with LIS means instant reporting without the need for dictatyping CHEAPER 21
Technologic Advances: “omics” DNA HT-Sequencing RNA Metabolomics Mass Spectrometry Protein Microarray Expression Profiling
What is “Correct”? The New Paradigm: Better • Objective classification by • mRNA expression • DNA sequencing • Response to therapy
The New Paradigm: Better • Synoptic Reporting • Complete • Standardized formats (CAP checklists) • Adaptable and flexible • No more verbose reports that no one reads! • Database technology • Statistics collection • Administrative tracking • QA monitoring • Academic data mining
The New Paradigm: Better(A Bit Controversial-still !!) Subspecialty Pathology • All cases reported by a pathologist with expertise in the specific subspecialty required • Benefits: • Better quality and faster patient care • Fiscal responsibility: 1 pathologist per case • Pathologist satisfaction – enhanced academic excellence • Challenges: • Requirement for appropriate staffing in all areas and Built in redundancy 25
Requirements for Full Adoption CHEAPER • Workflow integration • From the lab to the pathologist • LIS integration • Barcodes • Slide tracking and retrieval
Digital Pathology Enables • Remote access • Multiple viewers • Immediate access to the right pathologist at the right time BETTER 27
Computer-Assisted Diagnostics Automated analysis of: Measurement Mitoses Ki67 LI Other IHC intensity distribution Her2 FISH Hematology Cellavision More? ? Need for Westgard rules in AP? • QA of technical quality • Section thickness • Stain quality
