Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Daily physical activity (PA) is a predictor of survival in the general population and has become a significant outcome measure in patients with COPD. Recent studies have demonstrated an independent association between PA, hospitalizations and mortality. Increased PA has significant benefits for patients with COPD. In most studies PA has only been assessed at one time point. Little is known about longitudinal changes in PA and data on determinants of changes in PA are scant. Moreover, information on best approaches to enhance PA in a population with decreasing PA is missing. To evaluate the long-term effect of a coaching program which is aimed at helping patients with severe COPD (FEV1<50%) to enhance their level of daily physical activity, in addition to usual care. Furthermore, this study aims to evaluate mechanisms that are responsible for changes of physical activity over time such as sociodemographic factors, lung function, comorbidities, vascular function, exacerbations, and medication.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control
Usual care.
Active Comparator: Intervention
An increase in step count of 15% compared to baseline will be set as the minimal goal for each patient during 3 months.
Behavioral: Intervention
Patients allocated to the intervention group receive a pedometer. They are encouraged to be more active by using the pedometer to measure the number of steps walked daily. An increase in step count of 15% compared to baseline will be set as the minimal goal for each patient. Monthly telephone calls are indicated to encourage compliance with the protocol and motivate patients to enhance their level of activity. The coached program ends after three months but patients keep their pedometer and are encouraged to sustain an increased level of daily physical activity for additional 9 months (end of study).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Difference between the changes in number of steps per day (assessed over one week) from baseline to 12 months in the intervention group compared to controls.
Time Frame: 12 months
At visits, the number of steps per day will be assessed by a multisensory band (SenseWear Pro™; Bodymedia Inc., Pittsburgh, PA, USA) which will be worn on the upper left arm for 7 consecutive days.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of endothelial function by flow-mediated dilatation
Time Frame: 12 months
Flow-mediated dilatation measurements will be performed by ultrasonography of the brachial artery with a high-frequency (10.0-MHz) ultrasound-scanning probe proximal to the antecubital fossa. Flow mediated dilatation will be assessed by percent of baseline Diameter.
12 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description

12 months
Herat rate
Time Frame: 12 months
Heart rate (bpm) is measured in triplicate separated by 1-minute intervals after resting in supine position for 5 minutes in a quiet room.
12 months
Blood gas analysis
Time Frame: 12 months
Daytime blood gas analysis will be performed without supplemental oxygen and immediately analysed with a commercially available blood gas analyser (ABL90 Radiometer Copenhagen. Arterial pressure of oxygen (PaO2) and carbon dioxide (PaCO2) will be assessed. Further, oxygen saturation (SaO2) will be determined.
12 months
Questionnaire: Hospital Anxiety and Depression Scale (HADS):
Time Frame: 12 months
The questionnaire is especially designed for patients with physical impairment and assesses their symptoms of anxiety and depression. There are 7 items for each domain (anxiety and depression). Agreement on statements is expressed on a scale from 0 to 3 and domain scores are calculated by summing up the scores for the 7 items resulting in scores from 0 (no anxiety/depression) to 21 (depression/anxiety very likely).
12 months
Questionnaire: COPD Assessment Test (CAT)
Time Frame: 12 months
The test is designed to measure the impact of COPD on the patients' life and how this changes over time. The test includes 8 questions each with a scale from 0 to 5. The eight questions not only address respiratory or chest-related symptoms such as cough or sensation of mucus accumulation or chest tightness, but also more general complaints such as disturbances in sleep or decreased energy levels and daily limitations resulting from the disease. The total score will be assessed.
