Demands on technology
- Medical information systems can reach a high level of complexity as reflected in its functional diversity.
- Quick development and implementation is required and requested.
- Add-ons must be implemented rapidly at low cost. Maintenance costs must be minimal.
- Patient security requires fully reliable software.
- The use of software must be long-term, irrespective of platforms, operating systems or changes in technology.

The use of Model Driven Architecture™
All software solutions developed by network vita are based on the paradigm Model Driven Architecture Paradigma (MDA™). MDA was defined by the Object Management Group (OMG) who also defined other significant standards, such as CORBA (Common Object Request Broker Architecture), IDL (Interface Definition Language), UML (Unified Modeling Language), XMI (XML Metadata Interchange) or MOF (Meta Object Facility).Simply put, the MDA paradigm is used to create models of application which are independent from any platform. These models are then described in a standardized notation (UML). This enables the developers to attain a formal description of the software which is free from technology constraints and highly abstract.
By way of generators, the model is transformed largely into a platform-specific code. If generators are replaced by others, the application can be generated for other platforms without this changing the inherent logic of the program.
The platform independent representation is at the same time part of the documentation. By definition, this ensures that the documentation is up-to-date as it is the basis of software production. -
Despite an overall consent in our society that "to err is human", the management of errors in Western culture is often geared towards finding a scapegoat. In actual fact, however, the larger part (approximately 80%) of medical errors is rooted in system flaws.
In 2000 the American Institute of Medicine has published new data on medical errors in a series of studies entitled "to Err is Human". According to these studies, approximately 44,000 Americans die annually as a consequence of medical errors. The costs resulting from medical errors amount to $ 20bn. It is found that communication plays a key role in medical errors as communication in stress situations deviates drastically from communication in normal circumstances.
network vita has enhanced its medical information systems by functions which contribute to the elimination of errors. These include, for example, the plausibility check during data input, automated summaries of comprehensive information, as well as the automated production of reports.
