Based on the seven targets and requirements of patient safety of JCAHO in 2004, we plan to research on the construction of RFID technology in the operation room of hospital. In the research, we will study the possibility of combining the RFID technology and patient safety in the environment of hospital, we will construct the prototype of RFID technology, and we will transform the prototype into real system for the hospital after the verification of theory and practice. The purposes of this research are the increasing of patient safety, the integration of the existed HIS system, and the decrease of process cost.
