Plain English Summary
Background and study aims.
People with Chronic Obstructive Pulmonary Disease (COPD) have difficulty breathing due to narrowing of their airways. Pulmonary Rehabilitation (PR) improves Quality of Life (QoL) in COPD patients. Exercise is key to this treatment, but patients with more severe COPD may not be able to train at the required level. Non-invasive ventilation (NIV) uses positive pressure applied to the face via a mask and helps more severe COPD patients to exercise. The aim of this study is to find out how practical the Trilogy Ventilator is to use and the short- and long-term effects of NIV during exercise.
Who can participate?
Men and women aged 40 and above with COPD.
What does the study involve?
Suitable subjects will be invited to take part in the study and depending on which group they are assigned to will need to attend the hospital for a maximum of four visits. Participants will be randomly allocated into one of three groups:
Group 1: Standard treatment: exercise and oxygen.
Group 2: Exercise with NIV and oxygen.
Group 3: Continued supervised exercise program, with NIV, and oxygen if indicated at home.
Participants in group 2 and 3 will use the Trilogy Ventilator as their NIV device. The Trilogy Ventilator is a portable NIV device that is able to record information on use and the patients breathing. Before being discharged from hospital subjects will be required to undergo a medical examination (to obtain information such as gender, height and weight), complete a series of questionnaires, complete some standard exercise tests and be trained on the device to be used in the study. At the second and third visit subjects will be required to complete the questionnaires again and undergo some standard exercise tests (subjects in group 1 and 2 will receive the questionnaires by post). At the final visit all groups will need to complete the questionnaires and exercise tests again and return all of the study equipment.
What are the possible benefits and risks of participating?
We believe that the Trilogy device may allow for easier ward-based exercise and patients may feel more able to participate due the benefits of exercising with NIV. Patients may then benefit from continuing to exercise with the portable ventilator at home. The use of the device will be monitored by trained clinical staff. The patient can also easily remove their interface device should it become uncomfortable or make breathing difficult.
Where is the study run from?
Bristol Royal Infirmary (UK).
When is the study starting and how long is it expected to run for?
It is anticipated that the study will start recruiting in February 2013. Each patient is in the study for 3 months.
Who is funding the study?
Philips Home Healthcare Solutions (UK).

| Primary outcome measure | Health related quality of life (QoL) is measured using the EuroQol questionnaire (EQ-5D) (Brooks R, et al, 1996), will be used. The EQ-5D is a patient-completed questionnaire giving a single index value for health status and has been used in COPD patients (Cleland J, et al, 2007; Gonzalez-Moro J, et al, 2009; Harper R, et al, 1997; Heyworth I, et al, 2009; Nilsson E, et al, 2007; Pickard A, et al, 2008; Stahl E, et al, 2003; Stahl et al, 2005; Szende A, et al, 2009;). The EQ-5D will be completed as follows 1. On admission to the study 2. At point of discharge home 3. At 1, 2 and 3 months of the study. Completion of the EQ-5D at time points 1 and 2 will be supervised by the researcher. In all three groups, following discharge, the questionnaire will be posted out to the patients. |
| Secondary outcome measures | 1. Breathlessness during Daily Activity: This will be measured using the London Chest Activity of Daily Living questionnaire (Garrod R, et al, 2002). If NIV improves the ability to exercise and results in the patients being less breathless during exercise, daily activity should increase (Pitta et al, 2008). 2. Subjective Breathlessness: The MRC Dyspnoea scale (Burdon JG et al, 1982) will be used to assess the level of perceived breathlessness. The normal scale of 1 5 will be reduced to 3 levels Grade 1 and 2 those who are troubled by breathlessness on strenuous exertion or short of breath when hurrying; Grades 3 and 4 patient who need to walk slower than most people of their own age on level ground or to stop for breath after walking about 100 yards on the level; and Grade 5 those who were too breathless to leave the house or were breathless after undressing 3. Diary Card: We will give patients an optional symptom diary card to indicate changes in symptoms over time. It will also allow us to monitor drug usage and changes in therapy as prescribed. We will ask patients to assess cough, sputum production, breathlessness, wheeze, sputum colour, sleepiness, and activity levels, and will allow us to monitor reported and unreported exacerbations (Vijayasaratha K, et al, 2008). 4. Compliance with NIV on Exercise: Usage of NIV during exercise will be obtained from the integrated monitor from the Trilogy that records date, time, duration and other physiological data during each treatment session. 5. Activity Levels: From the ActiCal software, the levels of activity over a predefined period of time will be assessed, giving mean activity, number of steps and energy expenditure levels. 6. Demographics: In addition to recording gender, age, standing height and weight, we will ask the following information at baseline: living situation, education level, smoking history, alcohol use and disease co-morbidity. |
