[The present situation of the computer system for the clinical laboratory in Japan]

We report the present situation of the computer system utilization for the Clinical Laboratory in Japan. For this studies, the data were calculated to our purpose from the materials for statistics published by the Ministry of Health and Welfare, Japan Society of Medical Technologist, and so on. The results were as follows, 1) computer systems were used on the 85% of all hospitals, and the most of them were used for the medical office work included the payment office. At clinical laboratory, there was very few use the computer systems, which account for 25%. 2) In the field of the clinical laboratory, there was mostly used at clinical chemistry, next field was hematology, serology, urinalysis, and microbiology, respectively. 3) Total system for the hospital, including ordering system were used only 0.06% (208 cases) of all hospitals in Japan. We calculated the number of beds with a hundred thousand population, the spread of the computer system, the number of the out-patients, in-patients, and the utilization ratio of beds, then we compared with that data for all of the prefecture included Tokyo, Osaka and Kyoto. As a result of the calculation, the prefecture which the number of bed with a hundred thousand population was much more than another zone were the utilization ratio of beds was less than another area, and there was worth at the spread of computer system. We think there areas had the smaller hospitals than that of having highly spread of computer system.
