The study aimed to assess quality of life (QoL) in smokers with COPD who quit smoking after a pulmonary rehabilitation (PR) program compared to those receiving standard treatment.
A total of 437 smokers with COPD participated, with 113 entering a 12-week PR program while 324 continued with usual treatment, and their COPD Assessment Test (CAT) scores were evaluated before and after the treatment.
Results indicated significant improvements in QoL for the PR group (CAT scores dropped to 7-16) compared to the non-PR group (scores stayed at 20-26), as well as higher long-term smoking cessation rates among those who participated in PR.
