We empirically show that the effect of mobile EMR's technological characters on system qualities and usersatisfaction. For the study, the relationship among technological characters of mobile, EMR's system quality, EMR'sinformation quality, and user satisfaction were modelled and validated with hypotheses. An empirical test wasperformed for a path model using structural equation modeling on samples of 148 nurses in hospitals from varioussize and region. This study find that, for the overall sample, there are positive relationships among the technological characters ofmobile, EMR's system quality, EMR's information quality, and user satisfaction. And the results support that mobileis an effective method for EMR. Findings of this study have several theoretical and practical implications as follows : First, this study empiricallytested the relationship among technological characters of mobile, EMR's system quality, EMR's information quality. Second, the study shows that the technological characters of mobile should be considered for advance of EMRsystem's quality in mobile environment. And lastly, this study can practically suggest mobile healthcare informationsystem for process effectiveness.
