Healthcare Informatics suffers from the lack of information exchange among domain partners. Allowing cooperation among distributed and heterogeneous applications is a major need of current healthcare information systems. Beyond the communication and integration problems, medical information itself is by nature complex, combined with data and knowledge. The increasing number of standards and representation of the same data in different structures using these standards constitute another problem in the domain. Platform and implementation independency makes Web service technology the natural way to solve the interoperability problems in the healthcare domain. Standardizing the access to data through WSDL and SOAP rather than standardizing the electronic health record will help to overcome the integration problems among different standards in medical information systems. However, introducing Web services to the healthcare systems will not suffice to solve the problems in the domain unless the semantics of the services are exploited. This thesis aims to show that by generating web services and classifying these services through their functionalities, it is possible to achieve the interoperability among healthcare institutes, such as hospitals. The designed system is based on Artemis P2P Framework, and the annotation of the system is realized in the same framework.

Yes / The use of Information and Communications Technology (ICTs) in healthcare has the potential of minimizing medical errors, reducing healthcare cost and improving collaboration between healthcare systems which can dramatically improve the healthcare service quality. However interoperability within different healthcare systems (clinics/hospitals/pharmacies) remains an issue of further research due to a lack of collaboration and exchange of healthcare information. To solve this problem, cross healthcare system collaboration is required. This paper proposes a conceptual semantic based healthcare collaboration framework based on Internet of Things (IoT) infrastructure that is able to offer a secure cross system information and knowledge exchange between different healthcare systems seamlessly that is readable by both machines and humans. In the proposed framework, an intelligent semantic gateway is introduced where a web application with restful Application Programming Interface (API) is used to expose the healthcare information of each system for collaboration. A case study that exposed the patient's data between two different healthcare systems was practically demonstrated where a pharmacist can access the patient's electronic prescription from the clinic. / British Council Institutional Links grant under the BEIS-managed Newton Fund.
