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.

A wireless blood pressure measurement system was designed to facilitate the measurement of the patient's blood pressure and to transmit the measured data safely and reliably. Through PDA, radio frequency identification technology (RFID) and bluetooth technology, the function of reading patients' information and statistics and analysis of blood pressure, heart rate data was realized. The IDEA and RSA joint algorithms were used to encrypt the patients' data and the key of the IDEA algorithm to ensure the security of the patient' data. The test results showed that the system had high accuracy of measurement data, safe and reliable transmission, and improved the nurses' work efficiency.

OBJECTIVES: This paper describes an experience of implementing seamless service trials online and offline by adopting Internet of Things (IoT) technology based on near-field communication (NFC) tags and Bluetooth low-energy (BLE) beacons. The services were provided for both patients and health professionals. METHODS: The pilot services were implemented to enhance healthcare service quality, improve patient safety, and provide an effective business process to health professionals in a tertiary hospital in Seoul, Korea. The services to enhance healthcare service quality include healing tours, cancer information/education, psychological assessments, indoor navigation, and exercise volume checking. The services to improve patient safety are monitoring of high-risk inpatients and delivery of real-time health information in emergency situations. In addition, the services to provide an effective business process to health professionals include surveys and web services for patient management. RESULTS: Considering the sustainability of the pilot services, we decided to pause navigation and patient monitoring services until the interference problem could be completely resolved because beacon signal interference significantly influences the quality of services. On the other hand, we had to continue to provide new wearable beacons to high-risk patients because of hygiene issues, so the cost increased over time and was much higher than expected. CONCLUSIONS: To make the smart connected hospital services sustainable, technical feasibility (e.g., beacon signal interference), economic feasibility (e.g., continuous provision of new necklace beacons), and organizational commitment and support (e.g., renewal of new alternative medical devices and infrastructure) are required.

OBJECTIVE: The location services has been an important research area in the U-Healthcare. The location services in medical environment can be implemented by Radio Frequency Identification (RFID), and Received Signal Strength Indication (RSSI) which is the location tracking method by RFID. In this study, we was designed the Patient Location Monitoring System based on RFID using RSSI method. METHODS: The RSSI method is a distance measurement method from reference points to object using the Friis's Principle and the Triangulation. The Patient Location Monitoring System was implemented by XML Data transmitted from the Positioning Server to the application. The Patient Location Monitoring System was designed by C# of Visual Studio 2005 and MS-SQL 2005 Express. RESULTS: The Patient Location Monitoring System had the location-tracking average error of 90.50cm, the standard-deviation of 13.34cm in Open-Space test. And, the designed system had the location-tracking average error of 163.24cm, the standard-deviation of 16.85cm in Closed-Space Test. Also, a patient waiting-list guide performance of the Patient Location Monitoring System had successes of 85~100%. CONCLUSION: In this study, the Patient Location Monitoring System, combined with both patient location-tracking function and patient waiting-list guide function, was validated by experiments in medical environment and this system can be applicable to patient management and further applications.

OBJECTIVE: A system for reinforcing the patient safety has been established based on RFID (Radio Frequency Identification) technology in order to minimize a variety of potential medical errors which can take place in hospitals. The system is intended to prevent simple errors or misunderstandings attributed to manifold surgery, transfusion, and medication errors. METHODS: The RFID system was developed and established in one general hospital. The system was applied to managing the patient in the run-up to surgery during anesthesia preparation, transfusion, and anticancer medications, of which procedure information and the patient information are rechecked for assurance, respectively. RESULTS: With regard to the technological aspects, the system used 13.56 MHz of spectrum bandwidth and tags complying with ISO 15693 standard. The tag readers varied with the work, PDAs in the intensive care unit, and laptop computers in the anesthesiology department and on the general wards. After applying the system, we surveyed user's usage and satisfaction. CONCLUSION: The results of our survey indicated a high level of satisfaction with the RFID system in terms of reinforcing the patient's safety in medical environments. Respondents stated that patients were likely to wear an electronic bracelet, even if inconvenient, with their information revealed on the wrist and while going through extended medical procedures. Nurses had intentions to utilize the RFID system for managing hospital assets and tracking patients. A revitalization of the RFID system would be network stability, including the network environment, as well as quantitative effectiveness analysis.

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.
