Description of intervention(s) / exposure
People who agree to take part in the study will be randomly allocated to undertake pulmonary rehabilitation at home (early HomeBase)(commenced within 2 weeks of hospital discharge) or usual post-hospital care. People allocated to undertake early home-based pulmonary rehabilitation (n=83) will receive, in addition to standard (usual) care, an initial home visit from a physiotherapist to establish the exercise training program, facilitate setting of exercise goals and to ensure safety. This will be followed by seven once-weekly phone consultations with a physiotherapist, specially trained in motivational interviewing, to undertake self-management training and promote exercise progression. The total program duration is 8-weeks.

The home-based exercise training program will consist of a walking program (including use of a pedometer) and light weights for the arms and legs using readily available equipment in the home (eg. water bottles). Participants will be encouraged to undertake exercise on at least 5 days in the week, and to record their exercise participation in a home exercise diary. The overall goal of the program is for participants to work towards achieving at least thirty minutes of aerobic training on most days of the week. Exercise training intensity and session duration will be individualised and guided by participants perceived breathlessness (e.g BORG breathlessness scale, range 3-4). Home exercise diaries will be reviewed during the weekly telephone call consultation with the physiotherapist.

All participants will receive standard (usual) care, including medical management for their exacerbation based on COPD-X guidelines (which may include inhaled bronchodilators, systemic glucocorticoids and antibiotic therapy as indicated, controlled oxygen therapy and ventilatory assistance as required) and physiotherapy, commencing on the first day of admission. In line with guideline recommendations for management of an acute exacerbation of COPD, standard (usual) care may include referral to traditional outpatient (centre-based) pulmonary rehabilitation after discharge from hospital.

Participants randomised to the intervention (early HomeBase) group will be precluded from attending outpatient pulmonary rehabiliation during the intervention period (ie. Weeks 0-10 post hospital discharge). This is to prevent participants undertaking two pulmonary rehabilitation programs at the same time (home and centre-based). Participants in the intervention group will not be precluded from referral to or attending outpatient pulmonary rehabilitation at any time during the 12 month followup period.

At the beginning and end of the 8 weeks of the intervention phase, and after 12-months followup, participants will undergo measurements of functional capacity and health status. Hospital medical records and GP records will be reviewed to determine the need and frequency of hospital admissions. This will be tracked for 12 months for all participants.

Comparator / control treatment
All participants will receive standard (usual) care, including medical management for their exacerbation based on COPD-X guidelines (which may include inhaled bronchodilators, systemic glucocorticoids and antibiotic therapy as indicated, controlled oxygen therapy and ventilatory assistance as required) and physiotherapy, commencing on the first day of admission. In line with guideline recommendations for management of an acute exacerbation of COPD, standard (usual) care may include referral to traditional outpatient (centre-based) pulmonary rehabilitation after discharge from hospital.

In addition to standard care, participants randomised to the standard (usual) care control group will also receive a weekly telephone call for the period of the intervention (8 weeks), provided by a researcher not experienced in pulmonary rehabilitation. Telephone calls will not include any health information or advice on physical activity or exercise and are designed to serve as attention control. Specifically, control group participants will be asked about their general health status, and if they have needed to attend their GP or the hospital emergency department in the preceding week.

At the beginning and end of the 8 weeks of the intervention phase, and after 12-months followup, participants will undergo measurements of exercise capacity and health status. Hospital medical records and GP records will be reviewed to determine the need and frequency of hospital admissions. This will be tracked for 12 months for all participants.

Statistical methods / analysis
To detect a difference in hospital readmission between the intervention group (early HomeBase pulmonary rehabilitation) and standard (usual) care control group at 12-months following the intervention period, a total of 132 participants (66 participants in each group) will be required to detect a reduction in readmission rate to 30% with 80% power and a significance level of p<0.05. This assumes a rate of readmission of 57% in the standard (usual) care group. An additional 34 participants will be recruited to allow for 20% dropout. This is a conservative estimate for attrition, with our previous studies of home-based pulmonary rehabilitation demonstrating around 15% dropout rate; we will therefore randomise a total of 166 participants.

Analysis will use intention-to-treat principles, with inclusion of all participants regardless of program completion. For the primary hypothesis (readmission), the relative risk in the intervention group compared to control group will be reported with a 95% confidence interval. Secondary continuous outcomes will be examined using linear mixed models. A per protocol analysis will be undertaken including those who complete the program (greater than or equal to 70% of sessions attended). We will explore time to readmission using Cox regression.
