we observed a good correlation between the SGRQ, CCQ and CAT in this group of patients with severe COPD undergoing pulmonary rehabilitation. We found that CAT and CCQ have the advantage of being easier and faster to complete than the SGRQ. The need for help with the completion of the questionnaires was especially seen in patients with low education level.

Several studies of chronic obstructive pulmonary disease (COPD) have shown that pulmonary rehabilitation, consisting of at least three training sessions a week, improves exercise performance and health status. This study investigates feasibility, effect and economic aspects of a rehabilitation programme consisting of two sessions a week for 8 weeks. Twenty-four patients with moderate COPD were randomized to rehabilitation and 21 to placebo. Patients were assigned to an 8-week programme of exercise plus education (Exercise group) or conventional community care (Placebo group). The rehabilitation program was carried out in a hospital outpatient setting and consisted of 16 h exercise and 13.5 h of education. The exercise group received physiotherapy and education twice a week. Seven patients did not complete the programme. The characteristics of the 38 COPD-patients at baseline were the following: (mean +/- SD) forced expiratory volume in 1 sec (FEV1) 1.1+/-0.4 1 (47% of predicted), 6-min walking distance (6MWD) 413+/-75 m, score of St. George's Respiratory Questionnaire (SGRQ) 44+/-21. Health-status, assessed by SGRQ and The Psychological General Well-being (PGWB) Index, did not improve. Rehabilitation resulted in an insignificant improvement in the 6MWD [29 m (95% confidence interval: -8 -66 m)]. We conclude that a rehabilitation program consisting of exercise and education twice a week for 8 weeks had no effect on exercise performance and well being in patients with moderate COPD.

Does long-term oxygen therapy reduce hospitalisation in hypoxaemic chronic obstructive pulmonary disease? T.J. Ringbaek, K. Viskum, P. Lange. #ERS Journals Ltd 2002. ABSTRACT: The aim of this study was to determine whether long-term oxygen therapy (LTOT) reduces hospitalisation in hypoxaemic patients with chronic obstructive pulmonary disease (COPD). The circumstances of initiation of LTOT (start during hospitalisation versus start as an outpatient) and compliance with oxygen were also investigated (continuous oxygen therapy (COT) o15 h daily versus noncontinuous oxygen therapy (NCOT) v15 h daily).A total 246 COPD patients were studied, with each patient acting as their own control. Patients were divided into four groups: 125 patients on COT who started LTOT in conjunction with hospitalisation, 37 patients on COT who started LTOT as outpatients, 58 patients on NCOT who started LTOT in conjunction with hospitalisation and 26 patients on NCOT who started LTOT as outpatients. Admission rates, days spent in hospital and number of patients with at least one hospitalisation (ever hospitalised) were compared in two periods of 10 months before and after initiation of LTOT.Overall during the LTOT period, in comparison with the preoxygen period, the admission rates, hospital days and "ever hospitalised" were reduced by 23.8%, 43.5% and 31.2%, respectively. Among patients who started LTOT as outpatients, a tendency towards a higher effect in the compliant group was observed.This study shows that in hypoxaemic chronic obstructive pulmonary disease patients, long-term oxygen therapy is associated with a reduction in hospitalisation.

Weekly MT for 12 months improved walking time but had no influence on health-related quality of life or hospital admissions, compared with unsupervised daily training at home. The effect of the MT was closely related to adherence to the program.
