Today's medical institutions are constantly striving to improve the quality of medical care to avoid the occurrence of medical negligence; but unfortunately, medical negligence is still inevitable. Therefore, the issue of patient safety has always been one of the most important issues for the World Health Organization (WHO) and European, American and Japanese countries. It is also an important issue for the health care service systems of various countries around the world.

The operating room is indeed a high-risk, high-cost, complex, professional, and high-tech unit. Generally, surgery must be performed by a team composed of surgeons, anesthesiologists, anesthesia nurses, mobile nurses and other operating room personnel. In the case of medical errors, 16.9% of surgical adverse events are due to medical negligence. In order to reduce medical errors and negligence and improve the safety of pre-operative care for patients in the operating room, the pre-operative disinfection supply department counts and packs instruments; supervises the use of instruments during the operation; and recovers, sorts, counts and disinfects the instruments after the operation. work is extremely important. RFID radio frequency identification technology is used for the identification of surgical instruments, which should bring safety and efficiency to the above work, especially the identification/tracking of surgical instruments before and after use. The hospital can ensure complete and thorough disinfection, avoid the risk of nosocomial infection, or avoid Medical accidents occur where surgical instruments are left in the human body.
