Computerization has been applied in most areas of health care in recent years. But computerized standardized nursing care plans have not yet been adequately developed even though they can significantly contribute to an improvement in the quality of nursing care. Therefore, this study was done to develop computerized nursing care plans. For this purpose, the study had the following objectives ; 1) to develop a computerized program for standardized nursing care plans which include defining characteristics, relating factors, expected out-comes and nursing interventions 2) to test applicability of the computerized pro-grams to the actual clinical situation of the clinical nurse. Application of the system development life cycle by davis was used as the study methodology. There are five stages in this method : strategy planning development, system analysis, system design, system practice and system evaluation. The first four steps in this methodology were used in this project. Two clinical nurses were selected to apply this computerized program in the clinical situation. The results of the study are as follows ; 1) Ten standardized nursing care plans including defining characteristics, relating factors, expected outcomes and nursing interventions which had been proven to have validity in the clinical setting were computerized using the Foxbase Program. 2) These programs were applied to the actual clinical situation by two clinic친 nurses working at Severance Hospital. For further study, continuous revision should be done by the users. Evaluation related to the utilization of the program should also be done.
