Setting up a computer aided information system to meet the needs of the nurse is proposed. The IS will be designed on an adequate data model which will be the result of the analysis of the CN system and the nurse's work and will be run according to the method of the system engineering. The analysis will be object oriented. The data model will contain all the objects (nursing phenomena) from records of the process method of the nursing as well as the entities of the financial-statistical character.The prototyping will be used as a development method. The IS will be tested in practice. The computer solution will be implemented in the frame of a general software package such as Delphi for instance. The system will be used by community nurses at their work in health centres as well as on sites. Therefore the application will be written for PCs in the local area network. To meet the needs of the work on site, portable computers will be used. An adequate organizational model, including training and systematic follow-up of the sytem usage will be developed. The follow-up of the system utilization in practice will be made against a critical analysis of the computer CN information system. Findings of such analysis may result in changes in data model, computer solution and its utilization. The expected result of the project will be tested in a real environment and the prototype of the computer based IS will be evaluated. The IS will permit testing and demonstrations in broader practice thus assuring the basis for a system initiation of the computer support into nursing and for integration in health system.
