Persons with dementia are at risk of a missing incident, which is defined as an instance in which a demented person's whereabouts are unknown to the caregiver and the individual is not in an expected location. Since it is critical to determine the missing person's location as quickly as possible, we evaluated whether commercially available tracking technologies can assist in a rapid recovery.
This study examined 7 commercially available tracking devices: 3 radio frequency (RF) based and 4 global positioning system (GPS) based, employing realistic tracking scenarios. Outcome measures were time to discovery and degree of deviation from a straight intercept course.
RESULTS/CONCLUSION: Across all scenarios tested, GPS devices were found to be approximately twice as efficient as the RF devices in locating a "missing person." While the RF devices showed reasonable performance at close proximity, the GPS devices were found to be more appropriate overall for tracking/locating missing persons over unknown and larger distances.
痴呆症患者存在走失风险，走失事件定义为痴呆患者的行踪对照料者来说不明，且该个体不在预期地点。由于尽快确定失踪人员的位置至关重要，我们评估了市售追踪技术是否有助于快速找回。
本研究使用实际追踪场景，检测了7种市售追踪设备：3种基于射频（RF）的设备和4种基于全球定位系统（GPS）的设备。结果指标为发现时间和与直线拦截路线的偏差程度。
结果/结论：在所有测试场景中，发现GPS设备在定位“失踪人员”方面的效率约为RF设备的两倍。虽然RF设备在近距离时表现出合理性能，但总体而言，GPS设备更适合在未知且距离较远的情况下追踪/定位失踪人员。
