| Scientific title | The effect of a mobile safety alarm on going outside, feeling safe, fear of falling and quality of life in community living older persons: A randomised controlled trial |
| Study objectives | What is the effectiveness of a mobile alarm in changing the frequency of going outside of older people and what are their experiences about safety, fear of falling and quality of life? |
| Ethics approval(s) | The Medical Ethical Committee of University of Amsterdam/Academic Medical Centre Amsterdam reviewed this study and confirmed that as a social study, it did not require ethics approval. |
| Health condition(s) or problem(s) studied | New communication technology and services for older persons |
| Intervention | The intervention consisted of a mobile safety alarm with an inbuilt drop sensor. The mobile alarm was a prototype in development and uses a positioning system patented Europe-wide. The alarm went off by pressing a button. An integrated hand free function allowed the user to speak to personnel of an emergency call centre, even if the user didnt hold the device at their ear. If the user had fallen, the system automatically registered this and independently made a voice call to the emergency call centre. The Butler used a new kind of positioning system. The user of the alarm was located in 3 steps: their rough location was found via the cell phone network: from close-range, their position was pinpointed via an integrated tracking device and a beeping sound emitted from the device. This procedure allowed first-aiders to reliably find someone, even where conventional positioning systems such as GPS fail, such as in buildings or underground garages. |
