Abstract

Background: The effectiveness of pulmonary rehabilitation in advanced COPD is well established, but few data are available in less advanced disease.

Methods: In a 2 year randomised controlled trial, 199 patients with an average moderate airflow obstruction but impaired exercise capacity (mean (SD) forced expiratory volume in 1 s (FEV1) 60 (16)%, peak work load (Wmax) <70%) were randomised to the INTERdisciplinary COMmunity-based COPD management programme (INTERCOM) or usual care. Intervention consisted of 4 months multidisciplinary rehabilitation followed by a 20-month maintenance phase. Outcomes (4, 12, 24 months): health-related quality of life (St George’s Respiratory Questionnaire (SGRQ)), exacerbation frequency, MRC dyspnoea score, cycle endurance time (CET), 6-minute walking distance (6MWD), skeletal muscle strength and patients’ and caregivers’ perceived effectiveness.

Results: Between-group comparison after 4 months revealed the following mean (SE) significant differences in favour of INTERCOM: SGRQ total score 4.06 (1.39), p = 0.004; activity and impact subscores, p<0.01; MRC score 0.33 (0.13), p = 0.01; Wmax 6.0 (2.3) Watt, p = 0.02; CET 221 (104) s, p = 0.04; 6MWD 13 (6) m, p = 0.02; hand grip force 4.3 (1.5) lb, p<0.01; and fat-free mass index 0.34 (0.13) kg/m2, p = 0.01. Between-group differences over 2 years were as follows: SGRQ 2.60 (1.3), p = 0.04; MRC score 0.21 (0.10), p = 0.048; CET 253 (104) s, p = 0.0156; 6MWD 18 (8) m, p = 0.0155. Exacerbation frequency was not different (RR 1.29 (95% CI 0.89 to 1.87)). Patients’ and caregivers’ perceived effectiveness significantly favoured the INTERCOM programme (p<0.01).

Conclusions: This study shows that a multidisciplinary community-based disease management programme is also effective in patients with COPD with exercise impairment but less advanced airflow obstruction.
