ABSTRACT
One common and primary vision of eHealth is to achieve seamless interoperability between eHealth
systems to enable the delivery of the right information about the right patient to the right person at the
right time. However, the high sensitivity of the clinical domain and the vast differences in eHealth sys-
tems pose a great interoperability challenge for solutions that rely solely on prior knowledge of common
interoperability standards will not sufficiently scale. This chapter presents a service-based approach
that utilises domain ontologies combined with extensible problem models, enriched with domain termi-
nology and knowledge services to enable autonomous data governance and semantic interoperability.
The chapter addresses the resulting requirements and proposes a solution outlining the results from the
prototype of the approach.
INTRODUCTION
for integrated systems that can provide up-to-date
information about patients and their healthcare
is not only critical to the day-to-day running and
delivery of health functions but also potentially
means saving lives. It is increasingly expected
that patient health information is available at the
point of care irrespective of its location. This
Data sharing in the health domain is increasingly
being recognised as a critical factor for improving
healthcare and facilitating clinical research (Stead
