Public title
Can changing the way people with chronic lung disease think about breathlessness improve and sustain health outcomes?
Scientific title
In people with chronic obstructive pulmonary disease (COPD) does pulmonary rehabilitation combined with a cognitive behavioural therapy program for the sensation of breathlessness (BREVE) compared to pulmonary rehabilitation alone improve anxiety and functional exercise capacity at one, six and twelve months

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eight week comprehensive pulmonary rehabilitation (CPR) with a cognitive behavioural therapy program for the sensation of breathlessness (CPR + BREVE). The pulmonary rehabilitation program adheres to the recommendations of the COPD-X Plan 2008, and includes three exercise sessions (circuit training group therapy) and a two-hour education session each week (group therapy). The eight week CBT program (BREVE –Breathless. Recognise sensations, Explore thoughts and beliefs, Validate whether thoughts are useful or harmful, Evolve and change behaviour) includes one hour group work facilitated by a psychologist supported by an eight module workbook. Each module includes an educational component, individual reflective activity, practice tasks for the exercise sessions and homework.

Interventions and control occur seperately (i.e cycles of pulmonary rehabilation with and without the active intervention occur in randomised sequence)

Baseline (one month prior to intervention), one, six and twelve months after completion of intervention
Secondary outcome [1] 273030 0
The sensation of dyspnoea assessed via structured interview which includes, volunteered and endorsed descriptors and 10cm visual analogue scales for intensity and unpleasantness (anchored between 0 = no breathlessness / not unpleasant at all and 10cm = worse possible breathlessness / worst unpleasantness imaginable) .

Assessed at rest and immediately following the six minute walk test (6MWT) at timepoints, baseline (one month prior to intervention), one, six and twelve months after completion of intervention
Secondary outcome [2] 273031 0

Baseline (one month prior to intervention), one, six and twelve months after completion of intervention
Secondary outcome [3] 273032 0
Frequency of exacerbations and Health care usage. An exacerbation of COPD is defined as a change in self perceived symptomology necessitating a change of management classified as mild (increase in usual therapy), moderate (addition of steroids, antibiotics or both) or severe (requiring hospital attendance). Participants will keep a daily symptom diary including planned and unplanned attendance at health care providers.
Timepoint [3] 273032 0
Monthly for twelve months following completion of intervention
Secondary outcome [4] 273133 0
Accelerometery using the Actigraph GT1X3e to assess participants physical activity (minutes spent in moderate to vigorous physical activity, sedentary behaviours).

Baseline (one month prior to intervention), one, six and twelve months after completion of intervention
Secondary outcome [5] 273134 0
Use of time using the Multimedia Activity Recall for Children and Adults (MARCA) -a computer-assisted 24-hour recall instrument that adopts a time-diary approach asking respondents to recall their previous day in pre determined time slice
Timepoint [5] 273134 0
Baseline (one month prior to intervention), one, six and twelve months afer completion of intervention

Eligibility
Key inclusion criteria
People referred to Repatriation General Hospital to undertake the Comprehensive Pulmonary Rehabilitation (CPR) program will be eligible for inclusion in this study if they have a clinical diagnosis of COPD, intend to undertake the eight week CPR and have a forced expiratory volume (FEV1) < 80 percent predicted and best recorded ratio of FEV1 to forced vital capacity of < 70 percent (FEV1/FVC <70%).
Minimum age
No limit
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Participants will be only be excluded from this RCT due to the presence of cognitive or memory impairments (Mini-Mental State Examination score < 23/30), have clinically unstable COPD or co-morbidities which are likely to render exercise unsafe (determined by respiratory physician based upon change in medication or symptoms over the past two months) or are currently registered for lung volume reduction surgery or lung transplantation (risk of withdrawal from RCT).

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The staff of the CPR program will retain responsibility for receiving patient referrals, scheduling appointments for CPR and posting materials for the CPR program including an information sheet outlining this RCT. On attending the first assessment for CPR, the project officer will meet each potential participant to provide information, clarification and invite participation in the study prior to requesting written consent. The process of randomisation will be clearly conveyed. That is that in accepting the invitation to participate in this study, participants will attend one additional session per week which will provide an opportunity either to socialise with their group or to practice changing the way they think about breathlessness. The intervention offered is predetermined and will not be known by the project officer . The participant will only know which intervention has been allocated after the baseline assessments are completed. Potential participants will not be able to choose the intervention. Regardless of which group the participant is allocated to, all participants will receive the same CPR. Intervention and schedule will be provided to the participant in sealed envelop.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Pre-determined concealed, block randomisation using random numbers tables . Cycles of pulmonary rehabilitation (8 weeks each) are randomised to either intervention rather than individuals being randomised to intervention or control within each eight week block of pulmonary rehabilitation.
