Plain English Summary

Background and study aims?
Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases. People with COPD have difficulties breathing due to the narrowing of their airways. Pulmonary rehabilitation (PR) is a programme of exercise and education that is recommended to help patients with COPD. The aim of this study was to determine the additional effect of a PR programme on patients with mild COPD who are taking tiotropium (a drug that widens the airways in the lungs).

Who can participate?
Adult patients with mild COPD.

What does the study involve?
Patient records from local GP practices were searched to identify early-stage COPD patients. All patients were prescribed tiotropium for a minimum of 4 weeks before attending an assessment where their height and weight were measured and they underwent a lung function test and a walking test. Study questionnaires were also completed. Participants were then randomly allocated to one of two groups. One group took part in 8 weeks of once weekly, 90-minute supervised exercise and education sessions and were also encouraged to take part in a home-based exercise program. An exercise diary and pedometer was used to record home-based exercise participation. The other group were requested to continue normal care as instructed by their GP. All participants then took part in a follow-up assessment.

What are the possible benefits and risks of participating?
The benefits of taking part included regular physical activity under the guidance of a trained exercise practitioner. The education sessions were also deemed valuable as they were used to increase participants’ awareness of how to manage the symptoms of COPD. There are no known risks associated with participating in this study.

Where was the study run from?
University of Exeter (UK).

When is the study starting and how long is it expected to run for?
The study started in 2007. GP practice and participant recruitment was completed in 2009, with study findings published in 2010.

Who is funding the study?
The International Primary Care Respiratory Group (UK).

Scientific title

A randomised controlled trial of an intervention to promote the effects of Health Enhancing Physical Activity (HEPA) on physical and psychosocial outcomes in patients with mild Chronic Obstructive Pulmonary Disease (COPD) who are being treated with tiotropium

Study hypothesis

Chronic Obstructive Pulmonary Disease encompasses chronic bronchitis, emphysema, chronic obstructive airways disease, chronic airflow limitation, and some cases of chronic asthma. The disease is chronic, slowly progressive, irreversible and debilitating, and has a devastating effect on individuals, causing significant mortality and morbidity and carrying a huge cost to both the health service and society. The symptoms of Chronic Obstructive Pulmonary Disease include increasing breathlessness and fatigue which gradually removes the individual's ability to partake in everyday activities such as walking, shopping and even minor physical exertion. As patients tire quickly, progression of the disease requires significant modification to lifestyle and activity and has consequences on psychological well being, employment and finances with impacts on social functioning, family and mood.

Hypothesis:
What is the additional effect of a Health Enhancing Physical Activity programme (HEPA) on physiological and psychosocial outcomes in participants with mild Chronic Obstructive Pulmonary Disease (COPD) who are receiving tiotropium in accordance with National Institute for Clinical Excellence (NICE) guidelines?
