ABSTRACT: To develop a data warehouse system for cost analysis, based on the categories of the diagnosis procedure combination (DPC) system, in which medical costs were estimated by DPC category and factors influencing the balance between costs and fees.
We developed a data warehouse system for cost analysis using data from the hospital central data warehouse system. The balance data of patients who were discharged from Kagoshima University Hospital from April 2003 to March 2005 were determined in terms of medical procedure, cost per day and patient admission in order to conduct a drill-down analysis. To evaluate this system, we analyzed cash flow by DPC category of patients who were categorized as having malignant tumors and whose DPC category was reevaluated in 2004.
The percentages of medical expenses were highest in patients with acute leukemia, non-Hodgkin's lymphoma, and particularly in patients with malignant tumors of the liver and intrahepatic bile duct. Imaging tests degraded the percentages of medical expenses in Kagoshima University Hospital.
These results suggested that cost analysis by patient is important for hospital administration in the inclusive evaluation system using a case-mix index such as DPC.

ABSTRACT: Since September 1992, attempts have been made at Kagoshima University Hospital to develop the Medical Material Distribution Management System which helps to realize optimal hospital management as a subsystem of the Total Hospital Information System of Kagoshima University (THINK). As this system has been established, it has become possible for us to have an accurate grasp of the flow and stock of medical materials at our hospital. Furthermore, since September 1993, the Medical Material Distribution Management System has been improved and the Total Medical Material Distribution Management System has been smoothly introduced into the site of clinical practice. This system enables automatic demands for fees for treatment with specific instruments and materials covered by health insurance. It was difficult to predict the effect of this system, because no similar system had been developed in Japan. However, more satisfactory results than expected have been obtained since its introduction.

ABSTRACT: An optical disk filing system is an efficient approach to storing medical records; however, this system has not yet been put to practical use because it is usually a "stand-alone" type indirectly connected to a hospital information system. We have developed a medical record management system with an optical disk filing system connected to the host computer in the hospital information system. We can retrieve and display the medical records through the CRT (Cathode Ray Tube) terminals of the hospital information system at every ward and outpatient clinic. The patient's clinical information can be sent to several areas in the hospital using the hospital information system.

ABSTRACT: We have developed a hospital management system to analyze the large amount of the nursing information using a microcomputer system. In this system, we have combined the information from the patient database and the nursing database in order to evaluate the quality of medical care in the hospital. The utilization of a microcomputer is useful for filing and analyzing it and presenting the results in a variety of formats, including graphic representations.

ABSTRACT: At Kagoshima University Hospital, we have been developing the total hospital information system named THINK (total hospital information system of Kagoshima University), using a large-size computer system. In this system, the entry of data is done only once at the point of origin. The mutual use of data is done by various subsystems, and the user interface is uniformity. As a result of the speed, accuracy, and flexibility of the system's software, we have achieved efficient medical services and hospital management by a unified database; furthermore, we have improved medical care to patients and we can use this database for supporting not only medical education but also clinical research.

ABSTRACT: We have developed a computerized nursing system including a nursing information system, a nursing administration system and a nursing support system. This on-line nursing system is linked to the total hospital information system. This paper describes the purpose and concept of the system development. The nursing system can be utilized in the individualized planning, delivery and evaluation of patient care.
