Summary

Long-term evaluation of a coaching program which helps patients with severe COPD to increase their daily step count, in addition to usual care.

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.

Conditions

• COPD

Interventions

Type	Name	Description
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).
