Summary
Brief summary
People with chronic obstructive pulmonary disease (COPD) experience distressing
breathlessness and high health care utilisation. There is compelling evidence that pulmonary
rehabilitation improves symptoms and reduces hospitalisation, but is delivered to <10% of
patients who would benefit. The investigators developed a low cost model of pulmonary
rehabilitation that can be delivered entirely at home. The HomeBase model had equivalent
outcomes to centre-based pulmonary rehabilitation in a phase II efficacy trial, with higher
completion rates. The investigators hypothesise that a patient centred model offering a
choice between home or centre-based pulmonary rehabilitation may increase program completion
rates, with improved outcomes for patients and the health system.

This is a cluster randomised implementation trial investigating whether offering a choice of
home or centre-based pulmonary rehabilitation can reduce hospitalisation, improve pulmonary
rehabilitation completion and enhance patient outcomes in people with COPD. 14 pulmonary
rehabilitation programs located across Australia will each recruit 35 people with COPD.
Intervention centres: People with COPD will be offered the choice of centre-based pulmonary
rehabilitation or the HomeBase model. Comparison centres: Only the existing centre-based
model will be offered. The primary outcome is all cause, non-elective hospitalisation at 12
months. Other outcomes are symptoms, exercise capacity and quality of life at 8 weeks and 12
months; and health care costs at 12 months for full economic evaluation.
