Healthcare information systems are crucial
components for better coordination of healthcare. They focus on the proper
generation, transmission, storage, and retrieval of health data. It is obvious
that production of accurate, relevant, and timely health information is
foundation of good decision making. Rapid progress in wireless communications
and embedded systems result in wireless sensor networks to be employed even in
biomedical applications as well as their prominent deployment options. This
study proposes a healthcare information system framework which consists of such
components as; wireless sensor networks, cellular networks, a MATLAB interface,
a database, and a web based monitoring interface. A case study that includes
sensing, transferring, storing and web based monitoring processes of ECG signal
is also introduced in the study, so that the behavior of the system developed can
be tested. The results show that the framework presented here can not only be
employed as a healthcare information system, but it can also be used as an
infrastructure in related research activities and consequently, lots of time
can be saved from creating an experimental environment.
