Geographic Specificities
Average distance that people have to travel to
reach the nearest specialist living in the same
province or territory. Specialists tend to be
found in urban areas. Rural and northern
residents must travel considerable distances to
see specialists.

Definitions
  • Telehealth is the use of communications and
    information technology for clinical care,
    education and healthcare services at a distance.
  • Telemedicine is the use of communication and
    information technologies to provide or support
    clinical care at a distance.
  • Teleradiology is the electronic transmission of
    diagnostic imaging studies from one location to
    another for the purposes of interpretation and/or
    consultation.
  • Teleradiology represents 90 of telemedicine
    activity.
  • More and more telehealth transactions include
    transmission of images.

4
Numerous projects
  • All Provinces and Territories involved in
    Telehealth.
  • Over 100 active telehealth programs.
  • Many of those programs have to include medical
    images.
  • Heterogeneous networks and multi-vendor programs
    and telecommunications services.

5
A few examples
  • Health Infostructure Atlantic Project
  • Interprovincial Integration of Images and
    Information (TELE-i4)
  • Images shared within the 4 Atlantic Provinces
  • North Network
  • 80 sites through northern and central Ontario
  • Alberta Wellnet
  • Integrated system-wide health information
  • Provincial PACS project.

6
Electronic Health Record
  • Canada is focusing its efforts in improving
    healthcare by implementing an interoperable
    electronic health records.

7
What is an EHR ?
  • An electronic health record provides each
    individual in Canada with a secure and private
    lifetime record of their health history.
  • Electronic health record systems provide
    authorized healthcare professionals with rapid
    access to patient information anywhere anytime.
  • Today, only 9 of Canadians have an electronic
    health record.

8
Canada Health Infoway
  • Canada Health Infoway
  • Launched mid-2001, Infoway is an independent
    federally funded agency that works with the 10
    provinces and 3 territories to invest in
    electronic health records projects.
  • Mission
  • To foster and accelerate the development and
    adoption of electronic health information systems
    to have an interoperable EHR in place across 50
    percent of Canada by the end of 2009 and all
    Canadians covered by 2016.

9
Canada Health Infoway
  • Infoway acts as a strategic investor
  • invests with partners and funds 50 or more of
    the cost of a project
  • is involved in project planning
  • monitors progress of projects and quality of
    deliverables gated strategy links reimbursement
    to achievement of milestones.

Diagnostic Imaging Systems
  • Digital Image Repositories
  • Electronic distribution of DI results to all
    facilities, referring community physicians and
    specialists over reliable networks (all studies,
    any time, any where).
  • Shared DI Repository scaleable to 1.5 million
    studies/year (single/multi jurisdiction or large
    regions) integrated with IHE-compliant RIS
    solution(s).

Benefits of DI-r
  • Patient impact
  • Improve report turnaround time
  • Reduction in duplicate exams (132M/year in
    Ontario)
  • Reduction in patient transfers
  • Resources impact
  • Improve radiologist productivity by 25-28
  • Improve technologist productivity by 10-12
  • Improve clinician productivity

26
Benefits of DI-r
  • Cost impact
  • Reduction in film related costs (3.2-4 B)
  • Reduction in stand alone versus shared PACS
    system savings estimated at 40.
  • For the healthcare system
  • Overall cost 7.4 Billion but delivers 9.1
    Billion in benefits over 10 years.

27
Diagnostic Imaging Systems
  • Filmless working environment for all procedure
    types (CT, MR, X-Ray, ultra-sound, etc.)
  • Implementation of IHE profiles and EHR
    interoperability specifications (HL7/DICOM
    standards for image acquisition and report
    creation)
  • Use of optimal compression strategies for digital
    images.

Image Compression
  • Storage volume
  • Even if the cost of storage is dropping, the
    savings are largely surpassed by the increasing
    amount of data.
  • The cost of operation remains high.
  • 40 million diagnostic imaging exams are performed
    annually in Canada.
  • With an average legal retention period of 7 years
    upon provincial regulations.
  • Use of irreversible compression at 101 could
    save M100 million per year.

30
Image Compression
  • and transmission times
  • and if access to high bandwidth gets more
    available in local hospital networks, it is still
    premature to expect any health professional to
    use 100 mbps connections on their computers.
  • EHR networks cannot support large medical images
    and timely access to diagnostic images requires
    adequate level of compression.

31
Image Compression
  • The Canadian Association of Radiologists
    PACS/Teleradiology committee has accepted the
    principle of irreversible (lossy) compression
    for use in primary diagnosis and clinical review,
    using DICOM JPEG or JPEG-2000 compression
    algorithms, at specific compression ratios set by
    image type.
  • Adoption conditional to the results of a large
    scale evaluation study.

32
Image Compression
  • This study has been performed at Sunnybrook,
    supported by a grant from Canada Health Infoway.
  • Prior to that, CHI had commissioned 2 literature
    reviews and 2 legal assessments.
  • Radiologists have been enrolled from 9 out of 10
    Canadian Provinces.

33
Methodology
  • Based on previous studies, our evaluation
    resulted from the association of 2 accepted
    methods
  • Objective measurement of diagnostic accuracy with
    ROC analysis
  • Subjective image comparison with
    original-revealed forced choice (JND)

34
Methodology
  • 3 readers per session, 23 sessions, more than 100
    readers in total from all across Canada.
  • Had to read the images on the DICOM compliant,
    calibrated workstation they use in their daily
    activity.
  • The workstation had to be connected to the
    Internet ideally.
  • The answers were filled on-line and directly
    transferred to our server.

Noticeable degradation
No noticeable degradation
Difference in performance is due to the fact that
JPEG 2000 has good spatial resolution and
discards the low energy high-frequency
coefficients during quantization.
44
Recommendations
  • Lossy compression can be used at the lowest
    levels of compression tested, as there was no
    significant loss of diagnostic information at
    those levels.
  • No difference between Lossy JPEG and JPEG 2000 at
    the lowest levels of compression.

Public Health Systems
  • Solutions that support the identification,
    management and control of infectious disease
    cases and outbreaks that pose a threat to the
    public's health.
  • In March 2004, taking into account the lessons
    learned from the SARS outbreak and public concern
    about the ability of public health authorities to
    deal with emerging communicable disease threats,
    the federal government assigned Infoway the task
    of developing a communicable disease surveillance
    system in partnership with the provinces and
    territories.
