Abstract:
In many countries there are initiatives for building an integrated patient-centric electronic health record. There are also initiatives for transnational integrations. These growing demands for integration result from the fact that it can provide improving healthcare treatments and reducing the cost of healthcare services. While in European highly developed countries computerisation in healthcare sector begun in the 70’s and reached a high level, some developing countries, and Serbia and Montenegro among them, have started computerisation recently. This is why MEDIS (MEDical Information System) is aimed at integration itself from the very beginning instead of integration of heterogeneous information systems on a middle layer or using HL7 protocol. MEDIS has been implemented as a federated system where the central server hosts basic EHCR information about a patient, and clinical servers contain their own part of patients’ EHCR. Clinical servers are connected to a central server throug
h the Internet and the system can be accessed through a browser from a place that has an Internet connection. A user also has to have a public key certificate to be able to login. As health data are highly sensible, MEDIS implements solutions from recent years, such as Public Key Infrastructure and Privilege Management Infrastructure, SSL and Web Service security as well as pluggable, XML based access control policies.
