Studies in Health Technology and Informatics
This book series was started in 1990 to promote research conducted under the auspices of the EC programmes’
Advanced Informatics in Medicine (AIM) and Biomedical and Health Research (BHR) bioengineering branch. A
driving aspect of international health informatics is that telecommunication technology, rehabilitative technology,
intelligent home technology and many other components are moving together and form one integrated world of
information and communication media. The complete series has been accepted in Medline. Volumes from 2005
onwards are available online.

Editorial
The 13th World Congress on Medical and Health Informatics, Medinfo 2010, held in Cape Town,
South Africa has many forms of participation from preconference tutorials, workshops, keynotes, in-
vited presentations, scientific presentations, panels, demonstrations, and posters. The Organizing
Committee, led by Dr. Lyn Hanmer from South Africa, collaborated with the Scientific Program
Committee, led by Drs. Riccardo Bellazzi from Italy and Johanna Westbrook from Australia, to sculpt
an outstanding program. The Editorial Committee has tried to organize a subset of this rich content, the
scientific papers and abstracts of posters, into the Proceedings.
Our greatest challenge has been to make each paper have identical formatting. Only 10% of all submit-
ted papers exactly complied with the organizers instructions. Further work break down analysis shows
total editorial time (excluding meetings) of approximately 200 hours, evenly spread between posters
and papers. Of that 200 hours, two-thirds are corrections in to conference requirements, and one-third
is formatting in to publisher’s requirements. We thank Christine Archuleta for her diligent copy edit-
ing.
We have organized the paper Proceedings into 20 chapters, where the last chapter is comprised of the
abstract of posters organized by the authors self-selected theme. We have attempted to organize the
scientific papers in 19 chapters starting with the individual and moving through an ever expanding
view of organization and systems.
Of course, most papers could easily have fit into multiple sections, so we not only provide a keyword
index, but also a searchable CD-ROM version.

Preface from the Scientific Program Co-Chairs
The theme for the International Medical Informatics Association’s (IMIA) 13th World Congress on
Medical and Health Informatics, Medinfo 2010 is Partnerships for effective e-Health solutions. It is
well recognised that information and communication technologies have enormous potential for im-
proving the health and lives of individuals. Innovative and effective change using such technologies is
reliant upon people working together in partnerships to create innovative and effective solutions to
problems with particular regard to contextual and environmental factors.
Medinfo 2010 brings together the health informatics community from across the globe with a focus on
how we can work together and share our experiences and knowledge to promote sustainable solutions
to the challenges presenting to us all. This will be an historical event as Medinfo 2010 is hosted in Af-
rica for the first time.
The Scientific Program Committee (SPC) was presented with a strong field of 905 submissions meet-
ing the call of the congress challenge. This included 603 papers, 203 posters, 41 workshops/tutorials,
37 panels and 21 scientific demonstration applications. The final paper acceptance rate was 43%. All
papers were assigned to two or three reviewers who scored each of the papers and provided feedback
to authors. All submissions were categorised into one of four major themes (Hospital information sys-
tems, Consumer-health informatics, Knowledge management, National and International Health IT)
and submissions within each of these theme areas were re-reviewed by assigned members of the SPC.
The final program covers all aspects of modern health informatics, ranging from traditional topics,
such as hospital information systems, patient registries, nursing informatics, data integration, stan-
dards, interoperability issues and decision support, to new topics such as translational bioinformatics,
text mining, intelligent data analysis, emerging technologies, quality, social networking, workflow and
organizational issues. The papers have been selected with the guiding principle of including in the pro-
gram both high quality methodological research and high impact applications of health informatics. In
some cases, the authors achieved both goals.
A distinguishing feature of Medinfo 2010 program is the presence of several sessions on public health
and national and international initiatives to promote health IT. The scientific challenges to implement
large-scale initiatives are strongly related to the conference theme, as they rely on effective partner-
ships between all actors involved in health care informatics. The scientific rigor of the congress papers
can be seen both as a consequence and reflection of IMIA’s strategic decision to see its role as a pro-
moter of science and health IT throughout the world. Health Informatics researchers internationally are
rising to the challenge of providing robust evidence of the transformational effects of effective health
information exchange.
The Scientific Program Committee thanks all those who made submissions to Medinfo. Special thanks
also go to the worldwide team who reviewed these submissions and provided feedback. For the first
time the SPC organised a mentor scheme which provided the opportunity for researchers seeking to
x
submit papers to Medinfo to have their work reviewed by an international expert prior to the Congress
submission closing date. 42 papers were reviewed as part of this process. We thank the team of men-
tors who generously gave their time to support their colleagues as part of this scheme.
