背景资料：尽管夜间照明不良是福尔斯的一个重要风险因素（大多数福尔斯发生在夜间），但很少对改善从床到浴室的夜间照明的照明干预措施进行跌倒预防评估。目的：我们测试了一个假设，即自动导航灯可以减少夜间跌倒恐惧（FOF）并提高社区居住老年人的睡眠质量。研究方法：这项研究采用了一种实用的非对照前后设计，包括8个月期间的参与者，如果他们（i）年龄至少65岁，（ii）夜间独立行走，（iii）没有阻碍结果测量的认知或视听障碍。自动LED灯带（Gight（TM））安装在参与者的家中。主要结局指标为过夜FOF，评分范围为0-10。次要结果指标包括睡眠质量（0-10分）和跌倒率。此外，一个样本的参与者接受采访，他们的经验与Gight。结果：纳入64名参与者（平均年龄：80.8 ± 8.1岁; 89%独立生活）。平均研究时长为118天（范围：30-231天）。在意向治疗分析中，过夜FOF从5.5 +/- 3.0下降到3.8 +/- 3.2（p = 0.001），睡眠质量从6.7 +/- 2.4增加到7.4 +/- 1.7（p = 0.012）。研究期间的跌倒率太低，无法检测到变化。参与者赞赏Gight（8.4 +/- 0.8，10分），大多数（57%）报告FOF主观下降。结论：Gight在夜间FOF和睡眠质量方面显示出有希望的结果，但在广泛实施之前，应进一步评估照明干预对跌倒率的影响。
Background: Even though poor lighting at nighttime is an important risk factor for falls (and most falls occur during the night), lighting interventions to improve nightly lighting from bed to bathroom are rarely evaluated for fall prevention. Objective: We tested the hypothesis that an automated guiding light would reduce nightly fear of falling (FOF) and increase sleep quality of community-dwelling older people. Methods: This study had a pragmatic uncontrolled before-after design, including participants during a period of 8 months if they (i) were aged at least 65 years, (ii) ambulated independently at night, and (iii) had no cognitive or audiovisual impairments obstructing outcome measurement. Automated LED strips (Gight(TM)) were installed in the participants' homes. The primary outcome measure was overnight FOF on a scale of 0-10. Secondary outcome measures included sleep quality on a scale of 0-10 and fall rate. Additionally, a sample of participants was interviewed about their experiences with Gight. Results: Sixty-four participants were included (mean age: 80.8 +/- 8.1 years; 89% living independently). Mean study length was 118 days (range: 30-231). In the intention-to-treat analysis, overnight FOF declined from 5.5 +/- 3.0 to 3.8 +/- 3.2 (p = 0.001), and sleep quality increased from 6.7 +/- 2.4 to 7.4 +/- 1.7 (p = 0.012). The fall rate during the study was too low to detect changes. Participants appreciated Gight (8.4 +/- 0.8 on a scale of 10), and the majority (57%) reported a subjective decrease in FOF. Conclusion: Gight shows promising results for overnight FOF and sleep quality, but the effect of lighting interventions on fall rate should be evaluated further before widespread implementation.
