OBJECTIVE: Currently hospitals are working hard to make their hospital stand out from the rest in the medical market. The government is trying to hard to resolve the problem in regards to false claims for treatment expenses through issued medical prescriptions. There is a known limit to 1:1 service which needs much improvement. This proposed system will help prevent fake medical prescriptions from being issued. METHODS: In order to provide distinguished medical services for the next generation, we have designed and implemented a system that applies the Radio Frequency Identification standard, web services and mobile technology. RESULTS: In the proposed system, the Radio Frequency Identification card is issued to the patient and the hospital system can automatically recognize the patient and a simple SMS message will be sent. Through this method of communication 1:1 customer service can be accomplished. By applying the web services technology, any pharmacy can use the saved medical prescription code contained in the Radio Frequency Identification tag. This in turn resolves the systematic problems with illegal usage. CONCLUSION: Through this proposed system, we offer the functionality of easily applying the Radio Frequency Identification technology to various medical fields. By using a mobile device, it is possible to collect bio data remotely about a patient.

Focusing on the requirements of visual traceability for reprocessing of reused medical devices under the background of deep integration of intelligent medical treatment, a quality and safety traceability system for disinfection of reused medical devices is developed. The multi-dimensional data of the reprocessing chain of reusable medical devices are acquired in real time by the RFID mobile terminal handset and stored temporarily. The data package is formatted based on LoRa protocol and uploaded to the management and control platform in multi-threaded transmission mode for in-depth analysis and traceability. The corresponding prototype system is developed. The first-line operation and maintenance test results show that the prototype system has strong cooperation, strong operation robustness, and obvious advantages in the identification rate and other layers of sterile equipment package.

OBJECTIVE: Unauthorized exit of emergency patients could cause serious safety problems in the emergency room. If the entry and exit of emergency patients can be monitored by RFID (Radio Frequency Identification) technology, such safety issues may be resolved. METHOD: We determined the fundamental requirements of the system for emergency patient safety, and chose an active RFID tag to conduct the recognition test. Subsequently, we performed the entrance recognition rate test and safety test using pacemakers. After developing the entrance management programs, we implemented the system in the emergency room and collected data for 6 months. RESULT: The overall success rate of the entrance recognition test was 99.5%, and during the safety test, pacemaker oversensing due to noise did not occur. We intended to fulfill the fundamental requirements in developing entrance management programs. A total of 508 patients were given RFID tags for the study period, and the recognition failure rate was 4.7%. "Alert" pop-ups occurred 62 times. CONCLUSION: An active RFID entrance management system would be very useful for safety management in emergency room because the system enables detection of the unauthorized exit of emergency patients in real. time.
