Medical Information System Development: Practical Aspects

This paper deals with the development of the medical information system for automation blood transfusion station operations such as: accounting and availability monitoring of qualified blood in the storage, accounting of donors, monitoring of temporary and permanent blood-donating termination. The functional and software requirements are listed in the paper. Data domain modeling and system design were obtained on the base of the Kamyanske Blood Transfusion station (Dnipropetrovsk region) data and input requirements. The target audience of the information system are blood transfusion station employees. Object-oriented data domain analysis allows describing the functional features of a specific data domain in terms of classes, class objects, and their interactions. The results of data domain analysis are presented in the mathematical form. The scientific significance consists in developing an approach to utilization of system analysis, object-oriented and functional modelling of the data domain for the purpose of architectural design of the specific medical information system. Practical relevance of the proposed solutions results in creation of a multiple-use software product that is a source of and a tool for further development. Interface design has been focused on determining a set of form controls providing minimum user's physical effort towards required result and maximum level of protection against user's mistakes. The example of standardized and unified interface prototype is also presented.
