One of the patient's safety goals was used patient identification. This time mental patients used the same wristband identification as for common patients in hospital. Many obstacles faced in the hospital, such as wrist-band was often removed and always changed, or often blurred or not clearly to vision, so that was inefficient for management hospital, too risky to occur adverse event or medical errors. The aim of this study was developed a patient identification wristband for Mental patient Hospital, which different characteristics with common patient. Method for this study with clinical trial design and make a System information to connect wristband with data of mental patient in hospital. Result this research was a wristband identification can improve patient safety in mental hospital and simple system information. The wristband identification for mental patient in hospital was hard texture not make it harm, flexible and non-slashed very suitable for mental patients in hospital. The wristband identification put inside with RFID (Radio Frequency Identification) reader device. RFID used to make easier for all health worker in hospital to check the patient’s data. Excellences of RSIF were Tag has a unique ID and different in worldwide, regardless of its manufacture, so it is not possible to appear duplicate ID, Operation in Harm Environment. RFID can work in extreme environments such as high or low temperatures, high humidity to include wet categories, high noise environments, Reusable. RFID can be used repeatedly, and no line of sight required. In its use RFID was not needed to be faced directly with the reader.
