Typical drivers for IT adoption
Information Technology and Culture Change
• ICT has the capacity to bring improvements with:– Safety & Quality
– Efficiency Gains
– Remote Access & Services
– High Speed Access
– Management and Strategy
– Outsourcing Capabilities
– Education & Prevention
– Satisfaction & Fulfillment

Health is complex
• Some problems are so complex you have to be
highly intelligent and well informed just to be
undecided about them. (Lawrence J. Peter)
• Two Key reasons for this:
– Wickedness
– Complexity

What’s Hype in Healthcare ICT– What’s Not?
• “Care delivery organizations struggle with how to allocate limited
budgets as technologies and IT roles change. Each year, promising
IT innovations surface. Some never have an impact, others effect
evolutionary improvements, and a few drive fundamental changes in
business and IT strategies.”
Gartner report: “Hype Cycle for Healthcare Provider
Technologies”, 3 July 2006, Barry Runyon, et al.

How to Prioritize?
• Two key questions:
• How much value will an enterprise get from a particular
technology?
• When will the technology be mature enough to deliver that
value?
•
i.e. what are the technologies that have high or transformational value to Care
Delivery Organizations and that are likely to mature within the next few years?
•
The Priority Matrix - generated from the Benefit Rating and the Time to
Plateau information for each technology, as follows:

iii) Ontology and the Semantic Web
(Kerry Raymond, Michael Lawley)
– NEHTA is promoting SNOMED CT (SCT) to standardise the
clinical terms used by computer systems in healthcare
• SCT has its semantic foundations in Description Logic which is also
the foundation of the W3C's Web Ontology Language (OWL)
– We are investigating the use of OWL for representing, reasoning
about and processing SCT expressions
– Uses include semantic annotation of existing documents (text
and images) using SCT such that they can be queried or
otherwise processed, and
– Enabling the existing set of Semantic Web tools to be used with
health-related data

cont. Ontology and the Semantic Web
– In the context of Shared Electronic Health Records (EHRs), the
concept of Archetypes is being promoted by OpenEHR and for
CEN 13606
• Archetypes typically use a standardised clinical terminology such as
SCT both for values in a particular record and also to describe the
structures and fields of a record
• However, simple tagging of fields or values in an EHR is not
sufficient for performing the kinds of queries required by clinical
researchers
– We are investigating more powerful ways of combining SCT with
Archetypes to exploit the semantics inherent in SCT so that such
queries can be performed
– We collaborate closely with the E-Health Research Centre to
apply this work in context of Health Data Integration to avoid
creating yet more islands of data.

The Semantic Web - Peter Bruza & Amanda Spink
• Developing the capability using computational word meanings which
are extracted automatically from text.
• These meanings correlate with the those we carry around in our
heads. We can exploit the meanings in a number of different ways:
- they can act as signatures of terms in semantic web ontologies (and thus
help more effectively resolve issues of semantic heterogeneity);
- health care consumers have a wide range of experiences which, if shared,
can benefit others, not only issues dealing with illness, but also valuable
heuristics for getting around the horrendous bureaucracy- capturing these
experiences requires processing of unstructured info.
Dimensional reduction via singular value decomposition (SVD)
Projecting sense of self
P  Ik E
T
P = projected computational sense of self
I = approximation of sense of self in k approximation of the semantic space
E= axes of extraordinariness (a non-orthogonal subspace)

real world
“Abstract Concept” = eigenvector (intrinsic semantic space)
R
Intuition:
• If I projects significantly within bounds of axes (E), then I is in
a state of “extraordinariness”
• If I doesn’t project significantly onto E, then I is in a state of
CRICOS No. 00213J
“ordinariness”

iv) Sharing Health Knowledge
• “Health Information Literacy” (IT Faculty)
• “Sharing Health Knowledge in Indigenous Communities”
(Business Faculty)
• “Improving sexual and reproductive health and safety for
Queensland's remote indigenous communities through
culturally-appropriate multi-media information services”
(IT and USQ)
• “EHR based interoperability - openEHR and Archetypes
- between international healthcare institutions” (Info.Sys.)

Health Information Literacy
What is it?
Health Information Literacy (HIL) is “the set of abilities needed to recognize
a health information need; identify likely information sources and use them
to retrieve relevant information; assess the quality of the information and its
applicability to a specific situation; and analyse, understand, and use the
information to make good health decisions” (Medical Library Association,
2003)
Why research it?
Understanding and promoting HIL will assist Australians to age well; to live
longer with more years in good health, continuing for longer as part of the
Australian economic and social life.
This will in turn, help to reduce the cost and other pressures on the health
care systems, thereby allowing health services to direct attention towards
more substantial national health issues.

v) Medical Imaging and other related
projects (ISI/SEDC)
• Watermarking and Pattern Recognition of Medical Images (Current
project in collaboration with EHRC, UQ, GU, NICTA)
•
To investigate different watermarking methods and evaluate their suitability for
authentication of medical images w.r.t. visual quality, robustness, payload,
resilience to image manipulation, enhancement, histogram stretching.
• Pattern recognition and analysis of medical images (past projects):
• Analysis of shape changes of the hippocampus in MRI images to
determine epilepsy condition;
• Analysis of X-ray images of cervical spines to determine their
abnormality;
• Analysis of tongue images for traditional Chinese medicine
