Introduction

Frailty would affect 4 out of 5 people aged of 85 and over in France.

Methods

As part of a global project aimed to develop a multimodal system for the early detection of frailty among older adults living at home or in independent senior living apartments, we reported prospective quantitative study assessing a priori acceptability of this system based on Bel's integrative model devoted to the behavioral prediction use of an unknown technology. The platform is composed of 5 devices: a weight scale, a tensiometer, a wrist-worn step counter, an activity tracker and a tablet to exchange data with the aforementioned sensors over the internet. The inclusion criteria are: age 2: 80 years old, living at home or in independent senior living apartments, assessed as ‘robust’ or ‘pre-frail’. The a priori acceptability is assessed through self-evaluation questionnaires, mainly using a continuous scale (min-max score 1-7).

Results

We included 34 volunteers (24 women and 10 men), mean age 85.6 years (± 4.1), 24 of whom were classified as ‘robust’ and 10 as ‘pre-frail’. A priori utility of the multimodal system (mean score = 6.0 (± 0.9)), a priori intention of use (mean score = 5.9 (± 0.8)) and the rate of recommendation of the device before its first use (82.4% (± 17.4)) were clearly in favor of the device.

Conclusion

This study is in favor of an a priori acceptability and an a priori intention to use rather favorable to the developing system. Those results point a need for significant ease of use and almost-perfect functioning of this connected system for good acceptability.

用于老年人衰弱早期检测的多模态系统的先验可接受性

介绍

在法国，每 5 名 85 岁及以上的人中就有 4 人患有虚弱症。

方法

作为一个全球项目的一部分，该项目旨在开发一个多模式系统，用于早期发现居住在家中或独立老年公寓中的老年人的虚弱，我们报告了前瞻性定量研究，该研究基于 Bel 的综合模型评估该系统的先验可接受性未知技术的行为预测使用。该平台由 5 个设备组成：一个体重秤、一个张力计、一个腕戴式计步器、一个活动跟踪器和一个平板电脑，用于通过互联网与上述传感器交换数据。纳入标准为： 2 岁：80 岁，住在家里或独立的老年公寓，被评估为“健壮”或“虚弱”。先验可接受性通过自我评估问卷进行评估，主要使用连续量表（最小-最大分数 1-7）。

结果

我们包括 34 名志愿者（24 名女性和 10 名男性），平均年龄 85.6 岁 (± 4.1)，其中 24 名被归类为“强壮”，10 名被归类为“虚弱”。多模态系统的先验效用（平均得分 = 6.0 (± 0.9)）、先验使用意图（平均得分 = 5.9 (± 0.8)）和设备在首次使用前的推荐率（82.4% (± 0.8) 17.4)) 显然支持该设备。

结论

这项研究有利于先验可接受性和先验意图使用对开发系统相当有利。这些结果表明，需要使该连接系统具有显着的易用性和近乎完美的功能，以获得良好的可接受性。
