Early pulmonary rehabilitation after acute exacerbation of COPD: a randomised controlled trial.

ABSTRACT: Objectives:The aim of this study was to establish whether early pulmonary rehabilitation after severe exacerbation of chronic obstructive pulmonary disease (COPD) reduces mortality and hospital admissions, and increases physical performance and quality of life compared to rehabilitation initiated later in the stable phase of COPD. Methods:In a randomised controlled trial of 150 patients hospitalised with an exacerbation of COPD, participants were allocated to pulmonary rehabilitation either within 2?weeks after discharge or the same rehabilitation programme but initiated 2?months after discharge. Results:Early pulmonary rehabilitation did not prolong time to first hospital admission or time to death (hazard ratio 0.79, 95% CI 0.47-1.23, p=0.33) compared to rehabilitation in stable phase. However, 2?months after inclusion, pulmonary rehabilitation resulted in a significantly better improvement in the incremental shuttle walk test (33.9?m, 95% CI 4.18-63.7, p=0.02) compared to that in the stable phase. The difference in the endurance shuttle walk test was of borderline significance (140?s, 95% CI -2.03-282.76, p=0.05), but there was no significant difference concerning the COPD assessment test (-1.43 points, 95% CI -3.44-0.59, p=0.17). Conclusion:Early pulmonary rehabilitation after acute exacerbation of COPD led to a faster improvement in physical performance compared to rehabilitation initiated later in the stable phase, but did not improve survival or prolong time to hospital readmission.

Project description:BACKGROUND:Early pulmonary rehabilitation after exacerbation of chronic obstructive pulmonary disease (COPD) has previously been shown to reduce the risk of hospital admission and improve physical performance and quality of life. However, the impact of attendance at early rehabilitation programmes has not been established. OBJECTIVES:To evaluate the impact of increasing attendance to pulmonary rehabilitation on the risk of hospital admission, physical performance and quality of life in patients attending an early rehabilitation programme after an exacerbation of COPD. METHODS:This study was a secondary exploratory analysis of the randomised controlled trial COPD-EXA-REHAB study, involving patients hospitalised with an exacerbation of COPD. The COPD-EXA-REHAB study compared early pulmonary rehabilitation, starting within 2 weeks after an exacerbation, with standard treatment, that is, the same programme starting 2 months later. The present analysis included only the 70 patients allocated to early pulmonary rehabilitation. RESULTS:At 1-year follow-up, we found an association between the number of sessions attended and a reduction in hospital admissions (incidence rate ratio 0.93 (95% CI 0.88 to 0.99), p=0.02), corresponding to a 7% reduction for each session attended. Similarly, at 2-month follow-up, physical performance was positively associated with sessions attended: the mean Incremental Shuttle Walk Test result improved by 8 m with each session (95% CI 2.54 to 13.56, p=0.005) and the Endurance Shuttle Walk Test result by 44 s (95% CI 18.41 to 68.95, p=0.001). Quality of life, assessed using the COPD Assessment Test, was not significantly associated with the number of attended sessions, with the average score increasing by 0.15 points with each session (95% CI -0.35 to 0.65, p=0.55). CONCLUSION:Increased attendance at early pulmonary rehabilitation after exacerbation of COPD was associated with reduced risk of hospital admission and improved physical performance.

Project description:ObjectiveTo investigate whether an early rehabilitation intervention initiated during acute admission for exacerbations of chronic respiratory disease reduces the risk of readmission over 12 months and ameliorates the negative effects of the episode on physical performance and health status.DesignProspective, randomised controlled trial.SettingAn acute cardiorespiratory unit in a teaching hospital and an acute medical unit in an affiliated teaching district general hospital, United Kingdom.Participants389 patients aged between 45 and 93 who within 48 hours of admission to hospital with an exacerbation of chronic respiratory disease were randomised to an early rehabilitation intervention (n=196) or to usual care (n=193).Main outcome measuresThe primary outcome was readmission rate at 12 months. Secondary outcomes included number of hospital days, mortality, physical performance, and health status. The primary analysis was by intention to treat, with prespecified per protocol analysis as a secondary outcome.InterventionsParticipants in the early rehabilitation group received a six week intervention, started within 48 hours of admission. The intervention comprised prescribed, progressive aerobic, resistance, and neuromuscular electrical stimulation training. Patients also received a self management and education package.ResultsOf the 389 participants, 320 (82%) had a primary diagnosis of chronic obstructive pulmonary disease. 233 (60%) were readmitted at least once in the following year (62% in the intervention group and 58% in the control group). No significant difference between groups was found (hazard ratio 1.1, 95% confidence interval 0.86 to 1.43, P=0.4). An increase in mortality was seen in the intervention group at one year (odds ratio 1.74, 95% confidence interval 1.05 to 2.88, P=0.03). Significant recovery in physical performance and health status was seen after discharge in both groups, with no significant difference between groups at one year.ConclusionEarly rehabilitation during hospital admission for chronic respiratory disease did not reduce the risk of subsequent readmission or enhance recovery of physical function following the event over 12 months. Mortality at 12 months was higher in the intervention group. The results suggest that beyond current standard physiotherapy practice, progressive exercise rehabilitation should not be started during the early stages of the acute illness.Trial registration Current Controlled Trials ISRCTN05557928.
