OBJECTIVE: To investigate the impact of a pulmonary rehabilitation program on the functional capacity and on the quality of life of patients on waiting lists for lung transplantation. METHODS: Patients on lung transplant waiting lists were referred to a pulmonary rehabilitation program consisting of 36 sessions. Before and after the program, participating patients were evaluated with the six-minute walk test and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). The pulmonary rehabilitation program involved muscle strengthening exercises, aerobic training, clinical evaluation, psychiatric evaluation, nutritional counseling, social assistance, and educational lectures. RESULTS: Of the 112 patients initially referred to the program, 58 completed it. The mean age of the participants was 46 ± 14 years, and females accounted for 52%. Of those 58 patients, 37 (47%) had pulmonary fibrosis, 13 (22%) had pulmonary emphysema, and 18 (31%) had other types of advanced lung disease. The six-minute walk distance was significantly greater after the program than before (439 ± 114 m vs. 367 ± 136 m, p = 0.001), the mean increase being 72 m. There were significant point increases in the scores on the following SF-36 domains: physical functioning, up 22 (p = 0.001), role-physical, up 10 (p = 0.045); vitality, up 10 (p < 0.001); social functioning, up 15 (p = 0.001); and mental health, up 8 (p = 0.001). CONCLUSIONS: Pulmonary rehabilitation had a positive impact on exercise capacity and quality of life in patients on lung transplant waiting lists.

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls). Survival after LTx was the main outcome; invasive mechanical ventilation (IMV), length of stay (LOS) in intensive care unit (ICU) and in hospital were secondary outcomes. Kaplan-Meier curves and Cox regression models were used in survival analyses. Cox regression models showed that the PRP group had a reduced 54.0% (hazard ratio = 0.464, 95% confidence interval 0.222–0.970, p = 0.041) risk of death. A lower number of patients in the PRP group required IMV for more than 24 hours after LTx (9.0% vs. 41.6% p = 0.001). This group also spent a mean of 5 days less in the ICU (p = 0.004) and 5 days less in hospital (p = 0.046). In conclusion, PRP PRP completion halved the risk of cumulative mortality in patients with IPF undergoing unilateral LTx

Two-thirds of our sample with advanced IPF referred to lung transplant successfully attended PR and improved exercise capacity and HRQL, without association with markers of disease severity. No difference was found at baseline compared with subjects who were not able to complete the program.

OBJECTIVE: To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation. METHODS: This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied. RESULTS: According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (β = −0.087; p < 0.001) and the six-minute walk work (β = −0.285; p < 0.001). CONCLUSIONS: Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.

Background Pulmonary diseases represent a great cause of disability and mortality in the world, and given the progression of these pathologies, pulmonary rehabilitation programs have proven to be effective for people with chronic respiratory diseases. During the COVID-19 pandemic, telerehabilitation has become an alternative for patients with such diseases. Objective The aim of this study was to compare the outcomes (ie, functional capacity and quality of life) of telerehabilitation to those of usual care among patients who previously participated in face-to-face pulmonary rehabilitation programs. Methods We conducted a quasi-experimental retrospective study from April 2020 to August 2021. A total of 32 patients with chronic lung diseases were included and divided into the control and intervention groups. The intervention group performed telerehabilitation synchronously twice per week and was supervised by a physical therapist during breathing, strengthening, and aerobic exercises. Changes in the degree of dyspnea and leg discomfort were assessed based on changes in Borg scale scores. The control group did not perform any activities during the period of social isolation. Functional capacity was assessed with the 6-minute walk test, and quality of life was assessed with the Medical Outcomes Study 36-item Short Form Health Survey. Results The telerehabilitation group’s mean 6-minute walk distance decreased by 39 m, while that of the control group decreased by 120 m. There was a difference of 81 m between the groups’ mean 6-minute walk distances (P=.02). In relation to the quality of life, telerehabilitation was shown to improve the following two domains: social functioning and mental health. Conclusions Telerehabilitation programs for patients with chronic lung diseases can ease the deleterious effects of disease progression, be used to maintain functional capacity, and improve aspects of quality of life.

Objective: To determine independent factors related to the use of oxygen and the oxygen flow rate in idiopathic pulmonary fibrosis (IPF) patients placed on a lung transplant waitlist and undergoing pulmonary rehabilitation (PR). Methods: This was a retrospective quasi-experimental study presenting functional capacity and health-related quality of life (HRQoL) data from lung transplant candidates with IPF referred for PR and receiving ambulatory oxygen therapy. The patients were divided into three groups on the basis of the oxygen flow rate: 0 L/min (the control group), 1-3 L/min, and 4-5 L/min. Data on functional capacity were collected by means of the six-minute walk test, and data on HRQoL were collected by means of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), being collected before and after 36 sessions of PR including aerobic and strength exercises. Results: The six-minute walk distance improved in all three groups (0 L/min: ? 61 m, p < 0.001; 1-3 L/min: ? 58 m, p = 0.014; and 4-5 L/min: ? 35 m, p = 0.031). Regarding HRQoL, SF-36 physical functioning domain scores improved in all three groups, and the groups of patients receiving ambulatory oxygen therapy had improvements in other SF-36 domains, including role-physical (1-3 L/min: p = 0.016; 4-5 L/min: p = 0.040), general health (4-5 L/min: p = 0.013), social functioning (1-3 L/min: p = 0.044), and mental health (1-3 L/min: p = 0.046). Conclusions: The use of ambulatory oxygen therapy during PR in lung transplant candidates with IPF and significant hypoxemia on exertion appears to improve functional capacity and HRQoL.
