Technology Assisted Physical Activity Among Hospitalised Patients With Respiratory Disease

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate if patients hospitalised for medical disease will increase their time spent out of bed during hospitalisation through simple feedback about physical activities from a mobile device. Physical activity is measured by means of a pair of accelerometers embedded in band aids placed on the thigh and on the chest. The measurement is continuous and data is uploaded to a secure internet-server. Summaries of physical activity (bedrest, sitting, standing, walking) is computed and can be displayed on a mobile device (tablet) through a dedicated application. The study will be conducted as a controlled cohort study in a large tertiary public hospital in Copenhagen, Denmark. Patients admitted to Department of Respiratory Medicine will be included and will have their physical activity measured during hospitalisation. Half of the cohort will receive visual feedback about the amount of physical activity from a mobile device placed on the bed table. A total of 108 patients will be included resulting in 6 periods of 18 patients each.

Design Details

Primary Purpose: Supportive Care
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Interventional Model Description: There will be sequential inclusion to each cohort. Each sequence includes 18 patients (corresponding to the number of beds at the department). Thus the patients hospitalised during the first period will receive feedback (exposed cohort). In the second period the patients will not receive feedback (non-exposed cohort), and so forth. A total of 108 patients will be included resulting in 6 periods of 18 patients each.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Visual feedback of physical activity<br>Participants in the exposure cohort will receive usual hospital care and continuous measurement of physical activity by sensors collecting physical activity level during hospitalisation AND a monitor placed at their bedside that displays information about their physical activity level, in terms of time spent bedridden, sitting, standing and walking. This information will be visible to the health personnel, the patients and their relatives. | Device: Visual feedback of physical activity<br>* A monitor (tablet) will display the level of physical activity during hospitalisation. The monitor will be placed at the bedside (table).<br>Device: Measurement of physical activity<br>* A pair of accelerometers placed on the chest and on the thigh will measure the physical activity level during hospitalisation. The measurement is made continuously and stored on a secure web-server.<br>|
| Active Comparator: No feedback of physical activity<br>The participants in the non-exposure cohort will receive usual hospital care and continuous measurement of physical activity by sensors collecting physical activity level during hospitalisation. No visual feedback is provided. | Device: No feedback of physical activity<br>* There will be no visual feedback of the physical activity (no monitor placed at the bedside (table)).<br>Device: Measurement of physical activity<br>* A pair of accelerometers placed on the chest and on the thigh will measure the physical activity level during hospitalisation. The measurement is made continuously and stored on a secure web-server.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time spent out of bed during hospitalisation | Time (in minutes) spent out of bed measured in minutes related to the total hospitalisation time. The time spent out of bed will be recorded throughout the hospitalisation for a maximum of 7 days. | 7 Days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time spent sitting during hospitalisation | Time (in minutes) spent sitting related to the total hospitalisation time. The time sitting will be recorded throughout the hospitalisation for a maximum of 7 days. | 7 Days | 
| Time spent standing during hospitalisation | Time (in minutes) spent standing related to the total hospitalisation time. The time standing will be recorded throughout the hospitalisation for a maximum of 7 days. | 7 Days | 
| Time spent walking during hospitalisation | Time (in minutes) spent walking related to the total hospitalisation time. The time walking will be recorded throughout the hospitalisation for a maximum of 7 days. | 7 Days |
