Abstract: Background and aim: The long-term effects of pulmonary rehabilitation (PR) and maintenance programs in obstructive pulmonary diseases have not been sufficiently investigated, particularly in diseases other than COPD. This retrospective study aimed to examine the long-term results of individualized comprehensive outpatient pulmonary rehabilitation in patients with obstructive pulmonary disease. Materials and methods: This study is a single-center, retrospective cohort study. Between 2010 and 2019, 269 patients with chronic airway obstruction were treated in our multidisciplinary PR center at a tertiary training and research hospital, and they were divided into three groups based on their diagnosis: COPD, bronchiectasis, and asthma. Patients' perceptions of dyspnea, exercise capacity, inspiratory and peripheral muscle strength, body composition, quality of life, and psychosocial status were compared at the beginning, end, and 12th and 24th months of PR. Results: Improvements in dyspnea perception remained longer in asthmatics than in the other two groups. The increases in exercise capacity in the bronchiectasis and asthma groups lasted two years. All groups maintained their respiratory muscle strength gains at the end of the second year. Improvements in hand grip strength in the COPD and bronchiectasis groups have been sustained for two years, but in the asthma group, enhancements were lost in the second year. Even after the second year, quality of life was still better than the baseline in all groups, despite a worsening in the first year. However, groups anxiety and depression improvements were not sustained after the first year. Conclusion: The long-term effectiveness of PR in patients with bronchiectasis and asthma was similar to that of COPD patients. Therefore, multidisciplinary, comprehensive PR programs should be integrated into the management of patients with bronchiectasis and asthma. We also recommend structured follow-up programs to maintain gains and to detect the need for rerehabilitation.
