Prevention of medical malpractices related with surgical instruments is required. We have developed a new system that can obtain the information of surgical instruments, using radio-frequency identification (RFID) tags, during surgery in an operation room. The objective of this study was to investigate its accuracy. The number of surgical instruments was counted by visual observation as well as the system, and results were compared to make sure the accuracy of the counting system. The experiments were conducted during inguinal hernia surgeries and mastectomies.An acquisition rate was around 96% because the RFID tags were sometimes placed out of the radio communication range on the system. However, the system could recognize RFID tags when they were covered by blood because the system use radio communication technology. This study has proved that the system can obtain accurate information of surgical instruments during surgery.
