| Commencing
in 2002, the first stage of the project is now complete and
the resulting portal is available at:
http://www.bckonline.monash.edu.au
In
line with the original objectives of the project, the portal
represents a workable model or prototype. As such, it requires
further development and funding. Some funding has been
secured in order to develop Phase 2 of the project – entitled
BCKOnline2 – which is currently underway.
BCKOnline - Stage Two (BCKO2) [2005 Onwards]
Project
Description
This
project extends the first stage of BCKO, ARC-Linkage
2001-2003 funded research, which has resulted in a design
and a prototype BCKOnline portal
which provides differentiated access to breast cancer knowledge
resources. This portal contains user aware resource descriptions,
which it is matching with user needs information profiles.
We plan to further extend research portal's metadata repository
to move toward the concept of Smart Information Portals,
which aims at meeting knowledge and decision support needs
of health care consumers for quality online information.
We also explore to what extent these approach can be generalised
to other areas within the health domain and to online government
information provision.
This
project seeks to further research in the following ways:
-
Extend
the ‘intelligence' of the portal by incorporating some
adaptive system behaviour.
Current
portal does not support intelligence features, eg. “sound
like” search, learning and reasoning. We plan to extend
the current functionality exploiting a metadata-driven
resource management approach.
- Extend
the user-centric resource description focus of the portal.
Technical
and time factors have limited the prototype's ability
to automate some of the aspects of knowledge repository
maintenance. We are exploring the use of intelligent technologies
to address these deficiencies

Final Report [June 2004]
The
research has produced a user-centred portal to breast cancer
information resources. Although some further refinement
is desirable, and planned, the portal is now available
to the breast cancer community. The project has demonstrated
that by using a metadata schema to support the matching
of users with resources, it is possible to tailor information
provision to the particular needs of an individual user.
This demonstartes a new approach to online information
provision.
Project
Outcomes
-
The
quality analysis rationale developed for the project will
particularly equip women to make better informed health
and lifestyle decisions. Information access and patient
empowerment are not only important patient rights, but
there is a growing body of evidence that they contribute
to better clinical outcomes - clearly a significant national
benefit;
- These
aspects of the portal are of particular benefit to population
sectors, such as remote and rural communities;
- There
is strong
potential for the broader application of the concept
to other health areas and other disciplines. This has
raised prospects for a number of further research directions
and partnerships;
-
Using portal technology and metadata schema, the portal addresses
the major barriers to successful internet resource discovery
by the individual :-
ie. Information overload and relevance.
The portal interface empowers the user to specifically tailor
information (discovery and retrieval) according to her specific
needs, circumstances and personal values.
- Quality
reporting – provides the user with a ‘checklist’
of specific criteria which enables the user to identify
and prioritise criteria which are of immediate and specific
relevance to her need, and to the type of information sought.
-
The research has shown that it is possible to provide information
tailored specifically for women, at the time they need it,
via a portal which gives them access to worldwide information
without overloading them with too much information.
- It
has also demonstrated the value of advocacy groups working
with research groups to guide the research process. This
collaboration has been particularly successful and has meant
satisfactory outcomes for all concerned.
- The
research has highlighted the challenges of designing a medical
search engine that allows information pertinent to the needs
of consumers, to be accessed easily. Our organisation has
also been exposed to the implications of this type of technology,
such as maintenance, quality control, metadata, keeping
information up to date, and marketing.
- This
program provides the opportunity to strengthen links with
research for the overall benefit of the cancer community.
- The
project's goals and progress have been reported within
the breast cancer community via newsletters and more
broadly via print and electronic media. Whenever the
research has been reported, to a range of audiences
it has attracted much interest. International researchers
in ICT, patient information providers, and e-health
advocates have recognised its significance and potential
adaptability to other information contexts.
One
overarching characteristic of the entire project has been
the enthusiasm and support for the concept, and for the
actual prototype. This has been evidenced in all of the
research teams' conference presentations; and certainly
demonstrated in the usability testing, and the responses
gleaned from the target community – ie. Women and
their relatives who have breast cancer, and from breastcare
nurses who deal with patients on a daily basis. Further ‘evidence’ would
be that, since December 2004, and without a major 'marketing
campaign', the number of hits to the portal prototype has
exceeded all expectations. At
the time of writing, the prototype has received over 3000
hits in the space of 5 months. It is anticipated that with
further development and marketing of the service this
rate of usewill
increase - indicating the benefits to, and the response
from, the general community.
BCKOnline - Portal Usability Report [Nov. 2004]
Portal Usability / Evaluation Results
The
following section briefly outlines the highlights of the
results of the usability testing, which was completed in
July 2004. Since this testing, the portal interface has been
converted into a html format, and the process of adding another
600 records to the database has begun.
The major findings from the evaluation and usability testing
were:
- Ease of use and navigability - user's overwhelmingly reported
their success in locating and retrieving materials which catered to their specific
circumstances and needs. This was largely attributed to the 'personalised search page' and its intuitive nature.
- Users
reported most favourably on the 'value-added' feature of
the quality report. This enabled them to quickly and easily sort retrieved records
according to individual priorities and values
- Users
were enthusiastic as to the amount of Australian content
available and also the inclusion of materials which were often difficult to locate and
access, such as facilitative and experiential information.

Resource Selection and ‘Quality’
In
developing a framework for resource selection the Breast Cancer
Knowledge Online team has drawn on James Gardner’s ‘personal
outcomes’ perspective in which the success, or outcome, of
a medical service or system is measured according to the extent
to which an individual user’s expectations of that service
or system are met. Gardner identifies three categories of
outcomes:
- Clinical
Outcomes: which might focus on cure and symptom reduction
- Functional
Outcomes: which concentrate on increasing functional
status in specific areas
- Personal
Outcomes: which focus on items and issues that matter
most to people in their lives.
(Gardner, James (1997): Challenging Tadition:
Measuring Quality through Personal Outcomes, http://www.ncor.org/article1.htm)
In
the context of the BCKOnline portal, such a schema is particularly
relevant for the identification, description and final selection
of resources. It allows scope for the interplay of individual
preferences and values within the processes of indexing, cataloguing
etc. For example, the user may simply be interested in only
one aspect of a particular topic, yet for another subject
area she may require the entire spectrum of materials.
Gardner’s
3 outcome areas may be modified to deal directly with the
needs of the breast cancer population:
- Medical
outcomes are those related to the treatment and management
of disease, such as various treatment options, clinical
trial reports, drug news.
- Supportive
outcomes may be regarded as psychosocial outcomes; the
effect of the disease on the woman and her family; aspects
of social and psychosocial functioning either on a temporary
basis or as the long-term consequences of the disease; facilitative
information which may include addresses of support groups
or government assistance information.
- Personal
outcomes are those areas which matter most to the woman
and/or her family. This may overlap with the psychosocial
outcomes, but may be different and generally embody the
value system in the life of the individual woman. These
outcomes are often based on reflection of the experience
of the disease, including its treatment rigours, and incorporate
the stories of other women. The ‘voice’ of the health professional
would also be included in this category.
In
addition to developing the medical/supportive/personal taxonomy
the research team is also proposing to organise resources
included in the portal according to a number of subject categories
reflecting different types of breast cancer; various prevention
and risk factors; a range of surgical, medical and radiation
treatments; aspects of recurrence and advanced disease; palliative
care and complementary/alternative medicine.
The
research team is also developing resource selection criteria.
Although the criteria are not finalised, the following indicates
the team’s current approach to resource selection.
Resources
categorised as ‘medical’ must meet criteria for authorship
(credentials of creator and publisher must be clear); currency
(dates of creation, posting, amendment must be stated); evidence
(users will be alerted to the evidential nature of the resource,
for example whether it is consensus opinion or personal opinion,
based on a randomised clinical trial, case/cohort study etc.;
and references (evidence must be cited). Information about
the editorial policy and/or review process is also regarded
as desirable. The comprehensiveness of a resource, in particular
whether it acknowledges areas of disagreement or controversy,
is also relevant.
Resources
categorised as ‘supportive’ must also meet criteria for
authorship and currency. Their purpose (for example educational,
promotional, commercial) must also be evident. It is preferred
that these resources are also referenced.
Resources
categorised as ‘personal’ must establish the ‘credentials’
of the author and publisher. They must encompass a range of
views on a particular issues and should have relevance to
an Australian context. A panel of experts reflecting a holistic
approach to the care of women with breast cancer will also
contribute to the selection of resources in this category.
Terms of reference for this panel are currently being developed.
The
issue of ‘quality assessment’ has been, and continues to be,
considered at length by the research team. The project recognises:
- The
importance of personal meaning and individual values of
the potential user.
- The
‘value’ of diversity in the sense of not privileging information
according to source or type or content – the ‘decisions’
are to be based on user predilections and choice.
- The
often ambivalent nature of the information seeking process
for the individual with a serious illness.
The
team’s current thinking is that value-added information about
resource ‘quality’ will in part be drawn from the metadata
relating to authorship, currency and evidence. They will also
draw on models currently used elsewhere (ie HonCode) and the
principles contained within these.
2.
Metadata Schema Design
Current
approaches to web searching generally do not support the delivery
of timely information tailored to individual needs to the
extent needed for informed decisionmaking. This project proposes
a portal which harnesses metadata – structured resource descriptions
– to deliver relevant, user specific information. The project
has adopted AS5044, the Australian Government Locator Service
(AGLS) Metadata Standard, as the starting point for developing
a metadata schema which enables user-aware resource description.
Several extensions and modifications to the AGLS nineteen
element metadata set are proposed, including:
- Extension
of the Audience element to attach user profiling information
to a resource, including age group, disease stage, information
preferences, user type (family situation), locality/care
proximity
- Introduction
of a Quality element to describe resources in terms of the
review process, whether references are provided, evidence
type, purpose and balance.
- The
AGLS elements Function, Coverage and Mandate will not be
used.
- The
proposed typology of medical, supportive and personal will
be captured using the AGLS Type element.
Research
is now underway to confirm the encoding schemes which will
be used. A combination of AGLS schema, BCKOnline specific
encoding values and tools such as Medical Subject Headings
and/or Breast Cancer Victoria Glossary will be used.
More
information about AGLS is available at http://www.naa.gov.au/recordkeeping/gov_online/agls/summary.html.
3.
Portal Design and Software Selection
Research
is now underway to develop the BCKOnline prototype portal
as an intelligent decision support system. The team is currently
investigating how the following portal functionalities should
operate in the BCKOnline framework:
Information
retrieval – the use of user profiles and user-sensitive
resource descriptions is planned as the means supporting user-aware
retrieval. The user’s first interaction with the system will
be to select a profile that best matches her characteristics
and circumstances (age, disease stage etc). This input will
facilitate a metadata driven search of resource descriptions
in the portal repository, which in turn will point to the
user to relevant online or offline resources.
Adaptivity
– an adaptive system is continually trying to configure itself
so as to match the input data; in a sense, to ‘learn’ from
its use. It is not planned for the BCKOnline portal to have
advanced reasoning and adaptivity mechanisms, however it will
have the potential to monitor requests submitted and thus
to guide the future growth of the repository of resource descriptions,
and refinement of the user interface.
Prioritising
information – matching of user profiles and user-sensitive
resource descriptions will provide the user with listings
of the most relevant resources.
Explanation
facility – an intelligent system should be able to explain
to its users both the knowledge it contains and the reasoning
processes it applies. In the BCKOnline context, users will
be provided with value-added information about resources,
including their authority, provenance, currenty and quality
rating.
The
research team is investigating ‘HotMeta’ – the metadata repository
and search engine developed by the Distributed Systems Technology
Centre as the probable prototype engine.
Summary Report - User Needs Analysis: June 2003
This
phase of the project was completed earlier this year. Fifty-nine
women, eleven breast care nurses, and seven partners of other
family members participated in focus groups or interviews.
The
study used the technique of purposive sampling, often used
in qualitative research, to ensure that the major characteristics
considered to be relevant were included in the sample and
examined in the study. Data collection and analysis took place
simultaneously, and new insights were incorporated into subsequent
data collection. Categories and themes emerged from the data
– a grounded theory approach.

Key
Issues to Emerge from the Study
Timing
of Information Delivery
“now
I'm so much further down the track, the information is much
more readable and acceptable whereas earlier on it was too
confronting. I think now I'm quite comfortable reading things
and taking them in, whereas before I couldn't.”
Information Overload
“the
main thing is too many booklets, too much stuff to read… I had too much stuff to read.
And to find out the information, the specific information
that you need to have, you have to read, you have to read
through too many things. …. You think ‘Oh boy – there’s
too much, too much information here’, but you want to find
it, to know which way to find it.
Have I got to read through all that to find what I want?”
Relevance of Information
“but
I really found that a lot of the time the information that
you get, until it suddenly is part
of what you’re going through, it’s
not relevant and therefore perhaps you have read a lot of
information that you’re not taking in. It’s a process.”
Quality of Information
“how
do you know which one has credence and which one doesn’t?
I mean if you’re going to go into the internet and try to
find a site that’s going to tell you something, how do you
know that that’s not valid information? Just by reading it? I think that’s a lot of hogwash!”
Format
of Information
“That’s
what I wanted, I wanted diagrams. For the first time last
week I actually saw what invasive (lobular) carcinoma looks like as opposed to a ductal or different type of cancer.
I wanted to see exactly what was really going on.”
“all
my information is still sitting in the bottom of the
drawer and I was diagnosed nearly nine years
ago.. I have not opened any of it.
My information basically came from talking to other people.
I did not want to read because I didn't think I could take
it in. It was all too daunting.”
Gaps in Information and its Communication
“My
biggest gap is fertility. There’s not enough known about that
and I spoke to my surgeon last Monday and I have one child
and I was just told blanket, ‘you should wait two years before
you have another child’. And my question was ‘what if I do
get pregnant?’… And her answer to me…was, ‘well, we don’t
know’”.
Accessibility
of Information
“I’ve spent ages on the internet wandering all around, looking for things
that I don’t really want to know, but I find it interesting,
until I think very clearly what is the keyword that I really
want to know. And that’s the same with asking questions, that
sometimes we just don’t know. We know we want to know something,
but we don’t know how to get there.”
“All the terms. All the jargon and the drug names…. It’s not that hard. It’s fairly
formulaic. So how come it’s not accessible? There’s stacks
of information out there…. I should simply be able
to go and find that this is the research, this is the incidence
of success. It should have been reasonably easy to do.”
Issues
Emerging from Family/Friends Interviews
- Although medical information is important for families and friends
at initial diagnosis, partners in particular report a strong
need to know other people’s personal stories. This needs
seems to be greater, and is unmet to a greater extent, than
it is for the women themselves.
- There are substantial gaps in both the facilitative and supportive
information available to men.
- Succinct, and/or visual, information is important.
Some
Observations about the Findings/Themes
In
many areas the research reiterates findings from elsewhere.
For example, it is not new to observe that information needs
varying according to factors such as age, location or education,
or to note the importance of timeliness or the phenomenon
of information overload. However, through our qualitative
method we have moved beyond a simple understanding that these
characteristics have an effect - to obtain in-depth insights
about their importance and role. We have also explored how
generalisations, such as those regarding age and education,
do not take into account people who may not fit the norm.
The
truly innovative feature of this research is that it focuses
specifically on how available information is best utilised:
what type of information is most important at a particular
time in the disease trajectory? How is this information best
presented at this time? Many of the above observations are
in fact expressions of ‘relevance’: information has quality
and utility when women perceive it to be relevant.
