Dealing with the problem of co-ordination of subjects involved in kidney transplantation the paper displays new possibilities of using complex information systems for integration of dialysis centres and specialised health care units. Growing requirements of information system customers and development of object modeling methods stimulate creation of complex information systems designed to assist the work of medical staff. In the system presented in the paper information needs of customers are modeled by means of UML diagrams and the system itself involves a number of computer technologies, like inference in uncertainty conditions, artificial intelligence algorithms, knowledge bases, distributed processing, and Internet techniques. The system implementation covers numerous functional modules which are necessary to ensure efficient assistance of medical staff in their work, to improve the quality of patients’ life, and to carry out research in the fields of medicine and computer science.

The paper presents a general review of two approaches to modeling of urea concentration in serum after hemodialysis. The first approach is a well-established classic method, widely accepted by medical staff dealing with practical nephrology. The other one utilises the power of artificial neural networks, which is a novel application to that field. Unlike classic models that base on theoretical investigation, this technique uses only a number of data from previous treatment to construct a model through so called learning from examples.

The paper describes modelling of a complex information system supporting the work of a dialysis ward and scientific research carried out there. The system is designed to process multimedia information on patients, health care staff, and management of medical material and equipment. This information proves very useful for scientific research and supports physicians in taking decisions concerning extracorporeal dialysis equipment control. The decision-taking system together with optimal control algorithms are used to assess adequacy of dialyses, which results in higher efficiency of dialyses and improvement of life quality of dialysed patients. The new generation of information systems needs making use of scattered multimedia information, algorithms of computer intelligence and user-friendly communication. To meet these requirements it becomes necessary to apply environments enabling modelling of customer's requirements, information system structure and computer-man communication interface. The technology of component and object oriented modelling allows multiple code usage, and ensures higher reliability and easier modification of the system.
