     The purpose of this study is to clarify the precedence of secondary medical service areas(SMSAs) in Hokkaido that should introduce telemedicine. A patient trip model was developed based on the production-constrained model which is a family of spatial interaction models and a spatial analysis of patient trip was taken using geographic information system(GIS). The patient trip data were obtained from a report named “survey results of patient trip of National Health Insurance patients in Hokkaido in May 2000”. The number of patients was 79,458 for inpatient and 1,402,231 for outpatient. The attraction parameter β based on number of hospitals in SMSA and the distance parameter γ were calculated by the multiple regression analysis, respectively. Four kinds of patient trip patterns were formed by mean values of above two parameters of all areas in Hokkaido. The patterns were shown on GIS with traffic networks and geographic features. As the results, adjusted R2 of the model were high(0.754 for inpatient and 0.819 for outpatient), indicating that the patient trip in Hokkaido could be explained well by the number of hospitals in each SMSA and the distance among the SMSAs. In addition, it became clear that most of the SMSAs which had high precedence of introducing telemedicine were distributed in eastern areas of Hokkaido.

    Background: This paper describes the development of a survey instrument to measure use of, quality of and user satisfaction with electronic medical records (EMR) generated from the viewpoints of physicians. The reliability and validity of each construct of the instrument were examined by the analysis of responses of 460 physicians from 42 hospitals in Japan. The objectives of the study were to define the psychometric properties of the instrument as a basis for future demonstration studies and provide an instrument that can be used to monitor EMR from the viewpoint of physicians. Methods: Exploratory factor analysis was used to determine the degree to which each item within a construct is associated. The reliability of each resultant factor was computed using Cronbach’s alpha coefficient. Validity was examined through the factor analysis and by correlational analyses. Results: EMR extent of “use” resulted into three factors with good factor loadings and high reliability. EMR “quality” had two factors with good factor loadings and reliability. EMR “user satisfaction” construct had three factors but only one had acceptable reliability. “Use” and “quality” constructs were positively correlated with “user satisfaction”. Conclusion: The results of initial validity studies of this instrument were positive, but further validation of the scales is necessary.

     Almost all patients cannot adequately understand instruction given to them if the technical terms about adverse drug reactions are given to them. Also it is very difficult for novice healthcare professionals such as pharmacists to explain the information about adverse drug reactions in a language that is understandable to patients and to estimate the possibility of occurrence of adverse drug reactions based on patient’s complaints.
     Accordingly, we thought that patients could understand adverse drug reactions better if they were explained about them in simple terms of early symptoms of adverse drug reactions, and constructed a database of adverse drug reactions that consisted of the severe adverse drug reactions terms and simple words of early symptoms.

     Open Source Software(OSS) has driven the revolution of information technology. Although, most of the OSSs have been developed by volunteer community, some commercial companies recently tend to proceed development of open source software for commercial use.
     OSS has now been utilized in medicine. It is anticipated that has effect to cut off the high cost of medical infomation system. The development history of OSS in medicine starts from 1970 in the world. In Japan, Japan medical association has promoted their information infrastructure as OSS in the ORCA project.
     Nevertheless, there are much problem on the medical use of OSS, such as medical standard license is not compatible for OSS license. For the promotion of OSS in medicine, we must going on a deregulation program on medical informatics, and contribute not only in medical use but also in a whole OSS community as a member.
