However, up to now the role and the influence of an acute exacerbation (AE) during PR on the outcome of PR are unknown.Methods:In this retrospective analysis n=462 COPD patients (age: 54±7y, FEV1: 26±9% pred.) awaiting lung transplantation were enrolled for an inpatient PR. 401 patients completed PR (34±13days) without AE and 61 patients acquired an AE while performing PR (40±16 days; p=0.002). Patients with an AE continued PR in an individually tailored fashion. 6-minute walking distance, lung function testing and health-related quality of life questionnaire (SF-36) were performed on admission and discharge.Results:Patients with and without AE showed a comparable 6-minute walking distance (6MWD) (236±108m versus 253±122m; p=n.s.) and lung function (FEV1: 26±9% pred. versus 26±10% pred.; p=n.s.) at baseline. At discharge patients with and without AE were able to increase their 6MWD by 65±62m and 56±62m, respectively (both p<0.001, between group difference p=n.s.). The mental health component summary of the SF-36 also improved significantly (p<0.001) in patients with AE (11±18 pts.) and without AE (10±13 pts.). These improvements were not significantly different between the two groups. At discharge FEV1 was similar in patients with AE (27±9% pred.) and without AE (26±10% pred.).Conclusion:It seems that patients with end-stage COPD significantly benefit from PR with regards to exercise capacity and HRQL even if they acquire an AE during PR. Thus AE seems not to be a reason to discontinue PR. %U
