Abstract
Number of HIS terminal is increasing in CPOE(Computerized Provider Order Entry)-EMR(Electronic Medical Record) era. Many hospitals employ thin clients instead of fully-equipped computers as HIS terminals. However, in Japan, few hospitals use thin clients.
Hospitals in Japan have insufficient number of client computers although typical Japanese CPOE system has a lot of screen depth. Staffs have to logout from their computer on job interruption. It takes much time to resume to the original working screen.
Several parameters in job interruption and recovery compared between conventional CPOE and CPOE under remote-desktop environment. Parameters consist of number of mouse clicks, distance of mouse movement, number of screens and processing time. In some conditions, conventional system took 40 seconds to interrupt a job and return to original screen. It was 10 seconds to close a session and reopen on the remote-desktop clients. Some problems have to be overcome such as job session management and database record lock.
Server based computing and Blade PC system could reduce working insuf iciency as well as TCO(total cost of ownership) of HIS.
