AN EFFICIENT FAULT-TOLERANT OUTPATIENT ORDER ENTRY SYSTEM BASED ON SPECIAL DISTRIBUTED CLIENT SERVER ARCHITECTURE/

An automatic order entry system is very important for processing out-p atient information. This system not only helps physicians to enter the ir orders directly, bur can also reduce order communication error and thus improve medical quality. Therefore, many hospitals have high aspi rations to generate and implement direct order entry systems, but they are also concerned about the setbacks of system failure. In this pape r, we present an effective and efficient fault-tolerant order entry sy stem based on special distribution client/server architecture that sat isfies the requirements of out-patient order entry very well. From the experimental results carried out on a prototype, we found that this s ystem can improve the system response time of order entry and can also generate an operational method having a user friendly interface. The physicians can enter their orders easily, accurately, directly, flexib ly and at a faster rate by making choices from standardized and person alized menus in this system.
