| Summary: | 碩士 === 長庚大學 === 資訊工程研究所 === 96 === The rapid acceleration of population aging spotlights the increasing seriousness of problems facing the elderly. First and foremost among these is the deterioration of health and mental function that occurs as people age. The goal of this study is to construct a long-term care services information platform that provides a complete service of elder care and establishes a long-term patient health record to improve the quality of that care.
This information platform is composed of four systems. (1) Elderly Health Rating System – Assists in determining which elderly people require special care. It also aids in analyzing and planning the utilization of care resources. (2) Long-term Care System – Used to integrate care resources and arrange service resources suitable for the elderly. (3) Dementia Rating System – Provides caregiver organizations with long-term health assessments for their elderly patients, enabling them to plan suitable care for patients with dementia by tracking trends in their physical and mental deterioration. (4) Indoor and Outdoor RFID Safety Care System – Monitors the safety of the elderly, preventing them from leaving a facility unattended or entering hazardous areas.
This long-term care services information platform was already set up at a local long-term care center and a day care institution. It had become part of the care services provided at these facilities. There had already been several successful examples of the indoor RFID safety-care system preventing elderly patients from wandering out of the facilities and becoming lost. In order to more clearly understand the efficacy of RFID Safety Care System, this study devised two surveys and five experiments to test the system. (1) We surveyed 21 patients regarding their willingness to wear each of the two forms of RFID tags. 80% of those surveyed were willing to wear the name card sized RFID Tag, while willingness rose to 95% for the necklace RFID tag. The size and weight of these tags are the most effective factors on their willingness to wear tags. (2) Various numbers of RFID tags, ranging from one to twenty, were taken into a single restricted area to test the effectiveness of the Indoor RFID Safety Care System. On average, the system displayed the tag location and raised an alert in 4 seconds. (3) When two restricted areas were present and one to fifteen tags in each area of the Indoor RFID Safety Care System were used, alerts were triggered in an average of 4 seconds. (4) The Outdoor RFID Safety Care System’s ideal detection distance was within a 6.7m radius of the RFID Reader. (5) Through experimentation with the positions of outdoor RFID Reader and Tag, we discovered that 100% tag signal receipt is achieved when the Reader is positioned at 120 cm high (waist level), and the tag is worn at the side of the waist (110 cm high). With these settings, the erroneous detection rate is also at its lowest. (6) Outdoor RFID Safety Care System Alert Effectiveness – Through simulating a patient leaving the RFID monitoring range, we found that the system’s alert was triggered within 6 seconds on average. (7) RFID Safety Care System Satisfaction Survey - Of the four care staffs surveyed, 75% (n=3) were very satisfied with the RFID system’s benefits, stability, operation, and tag design.
