Short- and long-term hospital and community exercise programmes for patients with chronic obstructive pulmonary...

Pulmonary rehabilitation in patients with COPD has been shown to be beneficial but the optimal setting is not known. In the present study, the efficacy of a short-term community-based exercise programme was compared with a standard hospital outpatient programme. Additionally, the usefulness of community or home programmes in maintaining improvements in the longer term was studied.

Forty-three patients with moderate to severe COPD were randomized to one of the following three groups: a 3-month hospital programme then a 9 month home programme (Hospital/Home); a 3-month hospital programme then a 9-month community programme (Hospital/Community); or a 12-month community programme (Community/Community). The initial 3-month programme was analysed by comparing the Hospital group (Hospital/Home plus Hospital/Community) with the Community group (Community/Community). Six-minute walking distance (6MWD), quality of life (Guyatt chronic respiratory disease questionnaire, CRQ) and lung function were measured at 0, 3, 6 and 12 months and results were analysed using the Wilcoxon rank sum test.

At 3 months, there was a significant improvement from baseline in 6MWD in the Hospital group (81.3 +/- 18.3 m, P < 0.05, anova) but not the Community group (14.4 +/- 28.5 m, not significant). The difference between the groups was not significant (P = 0.058). At 3 months, there was a significant improvement in quality of life in the Hospital group (CRQ +16.3 +/- 3.1, P < 0.01, anova) and in the Community group (CRQ +10.2 +/- 4.9, P < 0.05, anova) but the difference between the groups was not significant. Following the initial 3-month programme, the dropout rate was high overall (73% by 12 months), and therefore data from the maintenance programme could not be analysed.

A 3-month community-based exercise programme for patients with COPD did not improve 6MWD. The long-term retention rates in the programmes were poor.
