Plain English Summary

Background and study aims
It is important for everyone to try to limit prolonged periods of sedentary behaviour (i.e. sitting and lying down) in daily life. Following an exacerbation (severe worsening of symptoms) of chronic obstructive pulmonary disease (COPD), sitting time can often increase which may not help individuals to maintain or improve their physical capabilities and quality of life. As a result, patients feel less able to attend pulmonary rehabilitation, a program of exercise, education and support to help people manage their COPD symptoms and function as normally as possible. It is therefore important to find effective ways for some people to sit less and move more after being discharged from hospital. We aim to look at whether it is feasible to deliver an intervention (i.e. program) developed to reduce sedentary behaviour at home for COPD patients admitted to hospital.

Who can take part?
Adults aged 40-85 with a clinical diagnosis of COPD who have been admitted to Glenfield Hospital, Leicester, UK for an acute exacerbation.

What does the study involve?
Patients are randomly allocated to one of three groups. Those in group 1 are placed in the usual care group. Those in group 2 are placed in the education group. Those in group 3 are placed in the feedback group. The education group receive information in the hospital about ways to reduce their sitting at home following discharge. The feedback group receive the same information as the education group plus feedback on their sitting behaviour from a wearable device via a mobile application. The usual care group receive standard care. Patients return to the hospital for a follow-up appointment after 4 weeks. We also collect data on their physical function, symptoms and body composition (that is percentage of fat, muscle etc.) . We will use information from this study help plan a larger study.

What are the possible benefits and risks from participating?
Patients may benefit from improved physical health in terms of reduced sedentary behaviour, increased activity and possibly improved physical functioning and well-being. No risks are foreseen but patients who reduce their sitting and increase their activity may experience associated breathlessness and other symptoms.

Where is the study run from?
Glenfield Hospital, University Hospitals of Leicester NHS Trust (UK)

When is the study starting and how long is it expected to run for?
January to June 2016

Study information

Scientific title

Feasibility of a home-based self-monitoring sedentary behaviour intervention for chronic obstructive pulmonary disease patients hospitalised following an acute exacerbation


COPD-SEAT (Sitting and ExacerbAtions Trial)

Study hypothesis

This is a feasibility trial of a home-based self-monitoring sedentary behaviour intervention for chronic obstructive pulmonary disease patients. The aim is to use the information from this study to inform a larger randomised controlled trial.

Chronic obstructive pulmonary disease (COPD)


Patients will be randomised (1:1:1) to one of three groups:
1. Usual Care (control): will not receive information or advice about sedentary behaviour. They will receive the educational material at the end of the follow-up appointment
2. Education: will receive written and verbal information about the importance of reducing their sedentary behaviour as well as top tips to achieve this
3. Feedback: will receive wearable self-monitoring technology which provides real-time feedback on their behaviour and prompts them to break up their sitting time

Added on 31/05/2016:
The intervention period will be 14 days following hospital discharge.

The intervention period will be 28 days following hospital discharge.

Intervention type



Drug names

Primary outcome measure

Assessing the feasibility of the processes, tools and management fundamental to the success of a future definitive intervention. Measurements include:
1. The number of eligible patients
2. Response rate of eligible patients
3. The number of eligible patients who refuse the intervention
4. Willingness of patients to be randomised
5. The practicality of delivering the intervention in the proposed setting
6. Follow-up rates, completion of measures, compliance with technology, level of missing data
7. The time needed to collect and analyse the data
8. The occurrence of adverse events related to the intervention

Added on 31/05/2016:
All outcomes are assessed at a follow-up appointment 2 weeks after commencement of the intervention.

Patient outcomes are assessed at a follow-up appointment 4 weeks after commencement of the intervention.

Secondary outcome measures

1. Sedentary behaviour as determined by inclinometry
2. Physical activity as determined by accelerometry
3. Physical function measured using the Short Physical Performance Battery, grip strength and 20m gait analysis using foot-worn inertial sensors
4. Breathlessness measured by the modified Medical Research Council dyspnea scale
5. Health status measured by the COPD Assessment Test and EuroQol (EQ-5D-5L)
6. Fatigue measured by the Functional Assessment of Chronic Illness Therapy (FACIT-F)
7. Anxiety and depression measured by the Hospital Anxiety and Depression Scale
8. Fear of falling measured by the Falls Efficacy Scale-International
Added 31/05/2016:
9. Body composition determined by body mass index index and waist circumference

9. Body composition determined by body mass index index, waist circumference and body fat percentage

Added on 31/05/2016:
All outcomes are assessed at a follow-up appointment 2 weeks after commencement of the intervention.

All outcomes are assessed at a follow-up appointment 4 weeks after commencement of the intervention.
