MEDSET -- an Integrated Technology for Modelling, Engineering, Deployment, Support and Evolution of Information Systems

This paper is devoted to the MEDSET (Modelling, Engineering, Deployment, Support and Evolution Technology) system for the development, deployment and support of information systems (IS) in clinical medicine and other poorly-formalized subject domains. This technology supports all stages of the IS life-cycle: modelling, engineering, deployment, support and evolution. The focus of the paper is on the evolutionary nature of clinical ISs. MEDSET allows ISs to develop in an evolutionary way, along different "dimensions": the number of supported business processes, the number of user functions, the number of users and the degree of formalization of data. The program component of MEDSET is based on Internet technology, so ISs built under MEDSET can be used in a remote mode as well as locally. The development of the EPR/NSI (Electronic Patient Records for a NeuroSurgical Institute) system for the N.N. Burdenko Neurosurgical Institute, Moscow, Russia is briefly described.
