研究概览
简要总结
The study has 1 primary research question and 5 auxiliary research questions regarding the use of bed mattress sensor for detecting pre-fall activities in elderly residents in old-age home setting:
Primary research question:
- Can bedside fall incidents per 1000 bed-days be reduced comparing the 6 months before and after the installation of the bed mattress sensor system, and compared to control group?
Auxiliary research questions: 2. Can the length of fall-related hospital stay shortens comparing the 6 months before and after the installation of the system and compared to control group? 3. What are the differences in fall characteristics comparing the 6 months before and after the installation of the system and compared to control group? 4. What is the number of different types of alerts and average time to turn off the alerts of the system (proxy measure of response time of the care staff), and how are they different to bed-exit alarm system? 5. What are the immediate care delivery of the staff upon the alert of the system, and how are they different to bed-exit alarm system? 6. What are the views and comments from the operation staff, residents and/or their family members on the usage of the bed mattress sensor?
详细描述
Study design
This is a 2-group quasi-experimental trial of comparing the outcome indicators between using the bed mattress sensor system and not using any bedside fall-prevention tools except restraints in residents living in Haven of Hope Woo Ping Care & Attention Home. Residents with moderate to high fall risk in one floor will be allocated to the experimental group and use the bed mattress sensor system for 6 months. Concurrently, residents with moderate to high fall risk in the other floors who do not use bedside fall-prevention tools including bed-exit alarm system, and ultra low bed will join the study as control group. We will also assess how the workflow and manpower changes due to the use of the sensor.
Subjects
Residents of 4 different floors in Haven of Hope Woo Ping Care & Attention Home will be recruited for the main analysis.

研究组 & 干预措施
Bed mattress sensor system
The experimental group uses the new bed mattress sensor system for 6 months.
干预措施: Bed mattress sensor system (Device)
Control Group
In the control group, participants do not use any of the following bedside fall-prevention tools: bed-exit alarm system, ultra low bed, and ripple bed during the same 6-month period.
结局指标
主要结局
Numbers of bedside fall incidents 6 months before and after the installation of the system and between the two groups
时间窗: 6 months before the 6-months trial period to the end of the 6-month trial period
The numbers of bedside fall incidents per 1000 bed-days 6 months before and after the installation of the system will be compared by retrieving data from the fall reports.
次要结局
- The number of immediate care delivery of the staff upon the alert(From the start to the end of the 6-month trial period)
- Qualitative measure: Fall characteristics of residents before and after the use of the system and between the two groups(6 months before the 6-months trial period to the end of the 6-month trial period)
- The number of detector alerts made by the sensor(From the start to the end of the 6-month trial period)
- Qualitative measure: Views and Comments from the operations residents and/or their family members on the usage of the pre-fall activity sensor(2 months after start of the 6-month trial period, and at the end of the 6-month trial period)
- Average time in seconds to turn off the alert(every day during the 6-month trial period)
- Qualitative measure: Views and Comments from the operations staff on the usage of the pre-fall activity sensor(2 months after the 6-month trial period, and the end of the 6-month trial period)
- The length of hospital stay due to bedside fall incidents before and after the use of the system and between the two groups(6 months before the 6-months trial period to the end of the 6-month trial period)
