Ambulatory Interdisciplinary Rehabilitation in Chronic Obstructive Pulmonary Disease (COPD)

Broad evidence exists on the beneficial effects of pulmonary rehabilitation on exercise capabilities and quality of life in COPD patients. Clinically relevant effects have been achieved by training programs of differing design regarding setting (inpatient vs. outpatient vs. home-based), duration (short-term vs. long-term) and intensity (high vs. low intensity).

While there is sufficient evidence to propose pulmonary rehabilitation its use is generally low in clinical practice. One reason may be that it is unlikely that costly programs are offered to a significant proportion of eligible patients. The ideal training program will therefore at the same time accomplish the greatest improvements regarding physical capabilities and quality of life and sustain them for the longest period at the lowest cost.

The purpose of the present study is to evaluate whether a continuous, low-intensity, low-cost, physiotherapist-led outpatient pulmonary rehabilitation program is a able to achieve significant long-term improvements of exercise tolerance and quality of life in moderate to severe COPD patients at a lower cost level than previously published programs.
