It is known that an exercise training and education programme known as Pulmonary Rehabilitation is beneficial to stable patients with COPD by reducing breathlessness, increasing exercise capacity and improving quality of life. We have recently performed a pilot study that has shown that early Pulmonary Rehabilitation has considerable short−term benefits in patients with COPD who have been recently discharged following a hospital admission for worsening of their symptoms [3]. We hypothesise that these benefits are long−lasting, and may reduce use of healthcare resources and costs to the NHS.
