- Conditions
- Chronic Obstructive Pulmonary Disease (COPD)
- Interventions
- Behavioral: Physical Activity InterventionBehavioral: Pulmonary Rehabilitation Programme
- Registration Number
- NCT02161393
- Lead Sponsor
- University of Ulster
- Brief Summary
The primary aim of this study is to assess the feasibility of conducting a trial to investigate the effectiveness of a physical activity intervention (physical activity consultation and a pedometer-based walking programme) versus pulmonary rehabilitation in improving physical activity in COPD.
Objectives are:
(i) to assess the feasibility (patient recruitment, adherence, drop-outs and adverse events) of delivering a physical activity intervention in the COPD patient population versus pulmonary rehabilitation; (ii) to explore users perceptions relating to satisfaction and benefits of a physical activity intervention versus pulmonary rehabilitation; (iii) to investigate between and within group change in physical activity, exercise capacity, quality of life, self-efficacy and changes in the transtheoretical model with the physical activity intervention versus pulmonary rehabilitation; and (iv) to examine the cost of delivering a physical activity intervention versus pulmonary rehabilitation for patients with COPD.
The hypothesis for this study is that it will be feasible to conduct a trial that will investigate the effectiveness of a physical activity intervention (physical activity consultation and a pedometer-based walking programme) compared to pulmonary rehabilitation for improving physical activity in COPD. The study will provide important information about interventions designed to promote and maintain physical activity, improve patient outcomes and increase patients' choice relating to exercise and physical activity interventions. It will provide a rationale and data for an adequately powered clinical trial evaluating the effects of a physical activity intervention.
- Detailed Description
A survey of pulmonary rehabilitation programmes mirrored the results of other UK studies and highlighted that there are not enough programmes available; currently in the UK less than 1.5% of patients with COPD receive pulmonary rehabilitation per year. Only a proportion of patients are targeted i.e. those with moderate to severe disease. The majority of programmes are outpatient-based and are supervised by clinicians. This structured and supervised format of pulmonary rehabilitation does not meet the needs of all patients with high numbers of dropouts and non-adherence; yet alternative options for increasing physical activity for patients with COPD currently do not seem to be offered.
A home-based pedometer-driven walking intervention offers an alternative method of delivering physical activity training that could be provided to larger numbers of patients, at a lower cost and with flexibility around life commitments. It would also provide patients with more choice when deciding whether to participate in exercise or physical activity.
To date no study has compared a home-based walking intervention to structured, supervised pulmonary rehabilitation or the patient preferences or cost of the two programmes. For this reason, there is a need to compare a home-based-walking intervention to the standard method of providing patients with physical activity training, i.e. pulmonary rehabilitation. Therefore this study is essential as it will assess the feasibility of conducting a trial to investigate the efficacy of a physical activity intervention (physical activity consultation and a pedometer-based walking programme) versus pulmonary rehabilitation in improving physical activity in COPD.

- Primary Outcome Measures
Name Time Method Change from baseline in physical activity will be assessed using step counts recorded with an Actigraph activity monitor. Baseline and at 6-weeks for PR group and 12-weeks for PA group The activity monitor is worn for 7 consecutive full days prior to the intervention, and 7 full days immediately after the intervention.
- Secondary Outcome Measures
Name Time Method Stage of change in terms of physical activity using the Stages of Change Questionnaire Baseline, and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation The Stages of Change Questionnaire is the temporal part of the transtheoretical model. It will be used to determine the current stage of change the participant is at in terms of their physical activity behaviour.
Confidence to undertake physical activity using Marcus's Self-Efficacy Questionnaire Baseline and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation Marcus's Self-Efficacy Questionnaire is a component of the transtheoretical model which will provide more detailed information on each individual's confidence to undertake physical activity in different situations.
Physical activity will be assessed using step counts recorded with an Actigraph activity monitor. At 18 (PR group) and 24 (PA group) weeks post randomisation Patients' perceptions of both interventions will be obtained via semi-structured interviews. At 6-weeks for PR group and 12-weeks for PA group Information will be collected with regards patient satisfaction with their exercise/activity, information regarding ease of execution, safety and tolerability of the programmes and the outcome measures, views about continuing exercise and suggestions for improving the programmes.
Global Rating of Change Questionnaire At 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation This is a numerical rating scale about their patient's perception of any change in their physical activity
Change from baseline in exercise Capacity using the Incremental Shuttle Walk Test Baseline, and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation Change from baseline in Quality of Life using the EuroQOL-5D Baseline, and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation Change from baseline in Quality of Life using the COPD Assessment Test Baseline, and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation Change from baseline in time spent in physical activity and in sitting using the International Physical Activity Questionnaire Baseline and at 6-weeks for PR group and 12-weeks for PA group, and follow up at 18 (PR group) and 24 (PA group) weeks post randomisation Feasibility of the interventions End of study For both interventions information will be collected on recruitment and retention, dropouts, adherence and adverse events which will be necessary to establish feasibility.
