CONFERENCING:The Use of the Aperio and

PolyCom PVX SystemsOssama Tawfik, MD, PhD

The University of Kansas Medical CenterPathology Vision Conf, Oct 2008



OBJECTIVES

1. Why going digital is valuable?2. What is wrong with the current

system?

3. Can we do better? And why do wehave to?



Why Digital Conferencing?

– Problem...

• Medicine is changing.

• Medical Practice and Teaching is moving away

from the Major Medical Centers into CommunitySettings.

• Medical Centers are redesigning themselves -clinics, surgi-centers, nursing homes anddoctor’s practices.

• Great majority of patient care will be outpatient,located outside the main Campus.



Why Telepathology?

– Problem...

• The growing physical separation betweenClinician and Pathologist is problematic incommunication...

• Traditional Pathology Reports will havelimitations in communication.

• How will we communicate with our clients

when they are across town, across the state oracross the world?



Why Telepathology?

– Problem...

• As medicine becomes distributed, it will becomeincumbent upon us as pathologists to find new

ways of communicating for clinical work,research and education.

• The primary mode of communication has alwaysbeen the pathology report.

• We may now have to rethink the way we report...



• Pathologists, radiologists, and surgeons

• digital slide/radiology conferencing on aweekly basis

• 500 breast needle core biopsies

• ERROR REDUCTION!!!!

• Evaluation of significantabnormalities/discrepancies

• Correlation with treatment plans for each

patient

Medical Error Statistics

• Colorado and Utah s tudy

– Adverse events (AE) in 2.9% of hospitalizations

– 8.8% of AE’s led to death (about 44Kdeaths/annually

• New York study

– AE’s in 3.7% of hospitalizations – 13.6% of AE’s led to death (98K deaths annually)

• Eigh th leading cause of death in USA



Dollar Cost of Medical Error

• Between $17 to $29 billion/year

– Half directly attributable to health care costs

– Other half combination of lost productivity, lostincome and disability



Goals of the IOM report

• Break “cycle of inaction’ concerning patient

safety and medical error

• Enhance knowledge base about medical error• Breakdown legal and cultural barriers which

impede safety improvement

• Shift from blaming individuals for past errors to afocus on preventing future errors by designingsafety into the health care system



Goals of the IOM Report (cont.)

• Improve knowledge base about medicalerror and safety improvement

• Develop tools to improve safety

• Cause significant monetary investments toachieve these goals



Institute of Medicine mandate

• Threshold improvement in quality

– 50% reduction in medical error in five years

Resources



“OUR PROBLEM”



• Aperio ScanScopeSystem

• PolyCom PVX videoconferencing System

“OUR SOLUTION”



• Pathologists, radiologists and surgeons

• Develop a web based pre-diagnostic work-up conference in which the pathologyslides and mammograms could beanalyzed together

• Goals:

– To insure adequate sampling

– To reach a proper diagnosis

– To determine the proper surgical/treatment

plans

Teleconferencing Challenges



Challenges

• It requires some training (learning curve)

• Psychological barrier!!!!

• Limitations in technology (view of smallarea of slide, length of transmission ofimages, internet connections, etc.)

• Image resolution, size of files transmitted



Benefits of telepathology

(telemedicine) • Better medical service

• More specialized service

• Primary diagnosis for frozen sections• Second opinion and consultations

(dermatopathology, neuropathology,cytopathology, etc.)

• Quality control

B fit f t l th l



Benefits of telepathology(telemedicine) cont.

• Cost saving/Time saving

• Exchange of ideas

• Improved collaboration with opportunity forresearch

• E-learning, clinicopathological mtg anddiscussion groups



CONCLUSIONS

• It can be cost effective solution to the

our university problem.

– It negated the need for an on-site

pathologist to staff the biopsy cases – Provided at-your-desk Telepath diagnosis
