Brief Summary

The purpose of this study is to investigate whether pulmonary rehabilitation (PR) is effective in increasing level of (a) physical activity (PA) and (b) self-efficacy in patients with chronic obstructive pulmonary disease (COPD). PR is an evidence-based multidisciplinary approach consisting primarily of a supervised exercise program with educational components. It has demonstrated high efficacy in improving dyspnoea, health-related quality of life (HRQoL) and functional exercise capacity in patients with COPD. Despite these improvements, there is no conclusive evidence that these benefits translate to an increase in PA in patient's day-to-day life. This is of concern as low PA is a predictor of all cause mortality, correlated with lower HRQoL, increased level of dyspnoea and higher number of hospital admissions in this group of patients. Self-efficacy is found to be an instigating force in forming intention to exercise and in maintaining practice for an extended time. Self-efficacy may be the key in determining whether a patient translates the improvement in exercise tolerance to actually being more physically active. Based on current knowledge, there is insufficient evidence that self-efficacy increases after pulmonary rehabilitation and no correlation has been made between level of self-efficacy and level of PA in these group of patients. Hence this study aims to find out whether the existing PR program increases level of PA and self-efficacy. Correlation between level of PA and self-efficacy will be made.

Outcome Measures

Primary Outcomes (2)

• Change in physical activity level after pulmonary rehabilitation

  Physical activity is measured using the Actigraph accelerometer, which is a small light weight device clipped onto a waist belt. Its output is vector magnitude units, steps, energy expenditure and activity intensity level. Patients will wearing the device for 5 to 7 days, before and after the program. The pulmonary rehabilitation program consists of 14 sessions, twice a week.

  Baseline measurement and after the program (approx Week 10)

• Change in level of Self-Efficacy using the Pulmonary Rehabilitation Adapted Index of Self-Efficacy (PRAISE) questionnaire scores

  Pulmonary Rehabilitation Adapted Index of Self-Efficacy (PRAISE) questionnaire is a questionnaire measuring the level of self-efficacy. It consists of 15 questions on a 4-point scale. It takes less than 10 minutes to complete.

  Baseline, and after pulmonary rehabilitation program (approx Week 10)

Secondary Outcomes (3)

• Change in 6-Minute Walk Test distance after pulmonary rehabilitation

  Baseline, and after pulmonary rehabilitation program (approx Week 10)

• Change in Hospital Anxiety and Depression Scale (HADS) questionnaire score

  Baseline, and after pulmonary rehabilitation program (approx Week 10)

• Change in COPD Assessment Test score

  Baseline, and after pulmonary rehabilitation program (approx Week 10)

Study Arms (1)

Patients with COPD

This is an observational study of patients with chronic obstructive pulmonary disease (COPD) who attend pulmonary rehabilitation, which is the routine standard of care in Guy's and St. Thomas' Hospital, London. It lasts for 14 sessions, twice a week and primarily consists of a supervised exercise program and educational sessions.

Eligibility Criteria

• Age: 20 Years - 90 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This study involves patients with chronic obstructive pulmonary disease (COPD), whose diagnosis is confirmed by spirometry

You may qualify if:

• Have chronic obstructive pulmonary disease or other respiratory conditions.
• Are aware of the about the referral and details of the program.
• Have consented and are able to attend the program.
• A diagnosis of COPD confirmed by spirometry (Forced Expiratory Volume in 1 second/Forced Vital Capacity \< 0.70 after bronchodilator) (GOLD, 2014)

You may not qualify if:

• No evidence of COPD on spirometry
• Acute exacerbations within last 4-6 weeks requiring hospital admission
• Evidence of ischemic heart disease/ acute changes on ECG
• Uncontrolled hypertension
• Inability to exercise independently or musculoskeletal/neurological conditions which would prevent completion of the course or limit participation in the course
• Lung cancer
