Study on weighting of amount of nursing care using data on index of patient's need for nursing and system approach.

The importance of appropriate staffing of nurses has been emphasized and optimal provision of nursing care has increased in order to improve the quality of nursing service. Since the introduction of the nursing information system in 1987, we have creatively categorized the classification of index of patient's need for nursing to collect ever-objective data on the index of patient's need for nursing and utilized it as an indicator to evaluate the amount of nursing care necessary for patients. We also weighted the index of patient's need for nursing and categorized it into categories A, B, and C based on the accumulated data on the index of patient's need for nursing, and calculated the cost of nursing care by adding the nurse salary data to the weighting. In addition, we developed a system in which measurement of amount of nursing care based on the data on the index of patient's need for nursing and calculation of nursing care cost could be done by utilizing the hospital Data Warehouse (DWH) and adopted a system approach that could contribute to improvement in patient service and make hospital management better.
