abstract
In critical situations, such as decision making in healthcare, is necessary to have access to all
of the patient’s information, the information must be reliable, and must be accessed in an easy
and fast way. These requirements make medical information systems of extreme importance.
However in today’s molds and with the advent of the Internet and mobile devices, a paradigm
shift, from the current isolated systems to interoperable distributed systems, that take
advantage of ubiquitous computing, is needed. The present work proposes an architecture that
aims to answer the needs of interoperability between heterogeneous systems and the need of
ubiquity of medical information systems. A prototype was developed that tries to provide
interoperability through a service-oriented architecture using web services. A mobile
component was also developed to enable ubiquitous access to medical information. This work
was based on the author’s knowledge about the Portuguese National Health Service.
