In the complexity and diversity of modem society, there is an urgent need for an information system which can systematically collect, manage and analyze data. Especially in the discipline of Nursing, a nursing information system is necessary to maximize nursing resources and improve nursing care in the present system which is faced with increases in client needs and multiple changes in recent hospital environment. This research was done to provide a basis for the development of nursing information system, which was extracted from an analysis of the demand of nurses and other medicine staffs in the general wards excluding the special unit(ER, OR, CSR, etc.). The ward nursing information system was analysed through analysis of nursing practice related to recordings, such as the work book, work list, kardex, other nursing practice recording on 24 wards, and open questionnaire of 288 nurses. Through this process, only four subsystems of output material for nursing practice were described in this study; (1) order communication system in nursing, (2) ward management system in nursing, (3) census reporting system in nursing, (4) materials management system.
