Effects of community-based pulmonary rehabilitation in 33 municipalities in Denmark - results from the KOALA project.

BACKGROUND: The positive impact of pulmonary rehabilitation (PR) in patients with COPD is well documented. However, little is known regarding the effect of this treatment in community-based settings. Since 2007, all Danish municipalities have been offering PR to patients with moderate to severe COPD, whereas patients with very severe disease or those suffering from many comorbidities were referred to outpatient hospital-based PR. OBJECTIVE: To analyze the effect of a standardized PR program conducted in a community-based setting on exercise capacity and health-related quality of life (HRQoL). METHODS: This is a real-life study including data from patients attending PR at one of the 33 healthcare centers in Denmark during the period 2011-2012. For the purpose of registration and for quality assurance, the KOALA database was established and this web-based registration instrument was offered free of charge to every municipality. Measures included sociodemographic and health-related variables and outcomes were exercise capacity and HRQoL assessed by 6-minute walking distance (6MWD) and the 15D questionnaire, respectively, at the beginning (baseline) and after completion of PR. Relative improvements in 6MWD and 15D were analyzed with multivariable linear models in patients who attended >50% of the sessions. RESULTS: A total of 581 patients completed the PR (72% of those included). We found statistically significant and clinically meaningful differences between baseline and end of rehabilitation values for both main outcomes with a mean change in 6MWD of 45 m, and the magnitude of improvement corresponds to other findings. Furthermore, relative improvements in 6MWD and 15D were correlated, as was the relative change in 15D and baseline Medical Research Council scores. CONCLUSION: Standardized, multidisciplinary PR conducted in a community-based setting showed good adherence to the program and produced effects on exercise capacity and HRQoL that were clinically meaningful and comparable in size to hospital-based PR.

Chronic obstructive pulmonary disease (COPD) rehabilitation at primary health-care centres - the KOALA project.

BACKGROUND: Implementation of pulmonary rehabilitation in primary health care in Denmark is a new challenge in the management of patients with chronic obstructive pulmonary disease (COPD). OBJECTIVES: To assess the feasibility of introducing a nationwide web-based tool for data recording and quality assurance in the rehabilitation programmes and to evaluate whether patients are referred correctly according to Danish guidelines for community based COPD rehabilitation. METHODS: Participation in the KOALA project has been offered to the municipalities since October 2007. As of October 2010, 62 health-care centres have been invited to participate. We present summary statistics and correlation analyses of the 1699 patients who have been enrolled so far. RESULTS: Thirty-three municipalities are currently engaged in the KOALA project. Descriptive analyses reveal that 33% of the patients do not meet the criteria for pulmonary rehabilitation in terms of dyspnoea upon exertion at the baseline visit. Furthermore, information on severity of COPD is missing for 18% of the attendants. The majority of the referred patients have moderate COPD, which is in accordance with the intentions of rehabilitation in the community. Statistical analyses show that COPD-level and grade of dyspnoea are positively correlated and expose significant correlations between both COPD-level and dyspnoea and 6 minutes walking distance (6MWD), incremental shuttle walk distance (ISWT) and quality of life. CONCLUSIONS: We conclude that the municipalities in general are interested in the KOALA project as a mean of data recording and sharing and as a quality instrument. Summary statistics show that there is room for improvement in referral and baseline assessments of patients suitable for pulmonary rehabilitation in a community setting.
