The elderly population is at high risk of functional decline, which will induce significant costs due to long-term care. Dependency could be delayed by preventing one of its major determinants: falls. Light paths coupled with personal emergency response systems could prevent the functional decline through fall prevention.
This study aimed to evaluate the effectiveness of light paths coupled with personal emergency response systems on the functional decline in an elderly population living at home. It is a secondary analysis on data from a previous cohort. In all, 190 older adults (aged 65 years or more) living at home participated. Participants in the exposed group were equipped with home-based technologies: light paths coupled with personal emergency response systems. The participants' functional status was assessed using the Functional Autonomy Measurement System scale at baseline (T0) and at the end of the study (T12-month). Baseline characteristics were evaluated by a comprehensive geriatric assessment.
After 1 year, 43% of the unexposed group had functional decline versus 16% of the exposed group. Light paths coupled with personal emergency response systems were significantly associated with a decrease in the functional decline (Δ Functional Autonomy Measurement System ⩾ 5) at home (odds ratio = 0.24, 95% confidence interval (0.11-0.54), p = 0.002).
This study suggests that light paths coupled with personal emergency response systems prevent the functional decline over 12 months. This result may encourage the prescription and use of home-based technologies to postpone dependency and institutionalization, but they need a larger cost-effectiveness study to demonstrate the efficiency of these technologies.
老年人群体功能衰退风险较高，长期护理会带来巨大成本。跌倒作为功能衰退的主要决定因素之一，若能预防，则可延缓失能。配备个人应急响应系统的照明路径可通过预防跌倒来防止功能衰退。
本研究旨在评估配备个人应急响应系统的照明路径对居家老年人群体功能衰退的有效性。这是对先前队列数据的二次分析。共有190名居家的老年人（年龄在65岁及以上）参与。暴露组参与者配备了基于家庭的技术：配备个人应急响应系统的照明路径。在基线（T0）和研究结束时（T12个月），使用功能自主性测量系统量表评估参与者的功能状态。通过全面的老年评估来评估基线特征。
1年后，未暴露组43%的人出现功能衰退，而暴露组这一比例为16%。配备个人应急响应系统的照明路径与居家功能衰退的减少（功能自主性测量系统变化值⩾5）显著相关（优势比=0.24，95%置信区间（0.11 - 0.54），p = 0.002）。
本研究表明，配备个人应急响应系统的照明路径可在12个月内预防功能衰退。这一结果可能会促使人们开具和使用基于家庭的技术来延缓失能和机构化，但这些技术需要更大规模的成本效益研究来证明其有效性。
