Psychological outcomes of an outpatient pulmonary rehabilitation program in patients with chronic obstructive pulmonary disease

STUDY/PRINCIPLES: The effects of an outpatient pulmonary rehabilitation program on psychological morbidity (anxiety and depressive symptoms) were examined in patients with chronic obstructive pulmonary disease (COPD). METHODS: The 26 rehabilitation patients with COPD were compared with 19 control patients with COPD similar in age, gender, COPD severity and other variables. Initial assessment included lung function testing, health status, exercise tolerance, dyspnea intensity and psychiatric interviews using Hamilton depression rating scale (HAM-D) and Hamilton anxiety rating scale (HAM-A). A pulmonary rehabilitation program was carried out during the following 2 months; psychiatric interviews and measurements of health status, exercise tolerance and dyspnea intensity were done again on completion of the study at 2 months. RESULTS: There was a decrease in HAM-A scores in the rehabilitation group and the decrease was statistically significant (P=0.010). On the contrary the HAM-A scores did not change in control group. The decrease in HAM-A scores in rehabilitation group was also statistically significant compared with the control group (P=0.042). There was no significant difference in HAM-D scores within the two groups and also there was no significant difference between the two groups in HAM-D scores. The health status, exercise tolerance and dyspnea intensity improved significantly in the rehabilitation group compared to the control group. CONCLUSION: This study shows that our outpatient rehabilitation program leads to a benefit in anxiety and depressive symptoms in COPD patients. The benefit was especially significant in anxiety symptoms. In addition to the improvement in psychological symptoms, the health status, exercise tolerance and dyspnea intensity were also significantly improved in COPD patients who underwent the rehabilitation program. This outpatient-based rehabilitation program was well accepted by the patients. The relatively simple design of the program makes it feasible independently of expensive equipment.

Results of an 8-week, outpatient pulmonary rehabilitation program on patients with and without chronic obstructive pulmonary disease

PURPOSE: To determine whether there is any difference in the effect of pulmonary rehabilitation (PR) on outcomes in patients with and without chronic obstructive pulmonary disease (COPD). METHODS: Retrospective analysis of medical records of all patients enrolling in PR over a 5-year period. RESULTS: A total of 422 patients enrolled in a multidisciplinary PR program from August 1999 to April 2004. Three hundred nine patients had COPD and 113 patients had diagnoses other than COPD. Three hundred seventy-nine patients completed the program. PR was conducted according to currently accepted guidelines. Measurements included the 6-minute walk distance (6MW) performed at the beginning and end of the program and quality of life as determined by the Chronic Respiratory Questionnaire (CRQ) at the beginning and end of the program. Both groups had significant improvements in the 6MW and all domains of the CRQ following PR. There was no significant difference in any of these outcomes between the 2 groups. The baseline forced expiratory volume in 1 second (FEV1) was not correlated with improvement in the 6MW in either group. CONCLUSIONS: There is no significant difference in improvement in exercise tolerance or quality of life following PR in COPD versus non-COPD patients. Baseline lung function does not predict improvement in exercise tolerance. PR is effective for patients with disability due to any chronic respiratory disease and not just COPD.     

中重度慢性阻塞性肺疾病患者肺康复运动强度的评估

目的探索反映中重度慢性阻塞性肺疾病（COPD）患者运动强度的较好指标和方法，用于制订和监测个体化运动强度。方法分析30例中重度男性COPD患者心肺运动试验中获得的运动强度指标，比较在不同最大摄氧量百分比（VO2max％）运动强度下各指标的分布，采用多元回归方法分析心率和Borg指数与VO2max％的相关关系。结果在取值上，心率储备百分比（HRR％）的实际值接近于VO2max％，而HRR％的预计值与VO2max％相差较远。在不同VO2max％运动强度下，HRR％实际值比预计值的分布变异更大。Borg指数越大越能准确反映COPD患者的VO2max％运动强度，Borg指数分别为3分（轻度气促）、4分（中度气促）和5分（比较重的气促）的运动强度分别达到60％、72％和78％VO2max心率和Borg指数与VO2max％的相关系数分别为0．807和0．834，在已知心率和Borg指数时，采用VO2max％运动强度的预计方程式可预计患者实际达到的运动强度。结论HRR％实际值能更好地反映VO2max％运动强度，建议采用心肺运动试验中获得的实际最大心率制订中重度男性COPD患者的运动强度。Borg指数是简单适用的运动强度制订和监测指标，建议中重度男性COPD患者在肺康复运动训练中应达到Borg指数4分。VO2max％运动强度的预计方程式可用于运动强度的监测。

Outpatient pulmonary rehabilitation in patients with chronic obstructive pulmonary disease

Objective

To evaluate an entirely outpatient-based program of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease COPD, using St.George’s Respiratory questionnaire (SGRQ), the 6-minutes walking test (6-MWT) and BODE index as the primary outcome measures.

Methods

A prospective, parallel-group controlled study of an outpatient rehabilitation program in 80 patients with COPD (67 men and 13 women; mean age 64.8 ± 10.6 years; FEV₁, 42.8% ± 7.6% of the predicted value. The active group (n = 40) took part in a 14-week rehabilitation program [3 h/wk, 1.5 h of education and exercise and 1.5 h of cycling]. The control group (n = 40) was reviewed routinely as medical outpatients. The following evaluations were carried out at study entry and after14 weeks: (1) pulmonary function studies; (2) 6-minutes walking test 6MWT; (3) quality of life; and (4) BODE index.

Results

The following patients completed the study: 35 patients (87.5%) from the active group (mean age, 63.7 ± 11.9 years; mean forced expiratory volume in one second (FEV₁), 41.9 ± 2.6% of the predicted value); and 36 patients (88%) from the control group (mean age, 65.9 ± 10.3 years; mean FEV₁, 43.33 ± 3.6% of the predicted value). We found no changes in pulmonary function parameters in the active group and the control one at 14weeks. On the other hand, there were significant changes within the components of the SGRQ (12.3 for the score total) for the patients of the active group but not for the patients of the control one (only 1.5 for the score total), we observed also a significant increase in the distance of the 6-MWT in the patients of the active group but not for the patients of the control one, and finally a decrease of two points (from 6 to 4) was noted in the score of the active group’s BODE index without any change in the control group’s one.

Conclusion

An outpatient-based of 14-week rehabilitation program significantly improved the quality of life and exercise tolerance without any change in the pulmonary function in patients with moderate COPD, and there was also a large decrease in the risk of death in rehabilitated patients as measured using the BODE index.     

Neurobehavioral improvement after brief rehabilitation in patients with chronic obstructive pulmonary disease

PURPOSE: Depressive symptoms, physiologic function, and cognition were examined in patients with chronic obstructive pulmonary disease (COPD) after 3 weeks of rehabilitation. METHODS: Patients with COPD completed measures of depression, neuropsychological function, exercise, and spirometry before and after a 3-week rehabilitation program. The 30 rehabilitation patients with COPD were compared with 29 untreated patients with COPD and 21 healthy controls similar in age, education, and gender. RESULTS: A significant group by time interaction effect was found on the Beck Depression Inventory (BDI). A significant interaction effect was also found on the 6-minute walk. Patients in the COPD rehabilitation program had decreased depressive symptoms and increased 6-minute walk distance compared with the untreated groups. Across the 3 groups, no significant interaction effects were found on neuropsychological tests. However, clinically significant improvement in sustained visual attention, verbal retention, and visuospatial ability were reported in the most impaired patients with COPD in the rehabilitation group. CONCLUSION: Compared with control groups, decline in depressive symptoms and increased exercise capacity occurred in patients with COPD after brief rehabilitation. Clinical improvement in visual attention, verbal memory, and visuospatial functions occurred in the impaired patients with COPD participating in treatment. Neurobehavioral improvements after such a brief rehabilitation intervention are relevant for clinical care and warrant continued investigation in well-designed clinical trials.     

Home-based versus outpatient pulmonary rehabilitation program for patients with chronic obstructive pulmonary disease: A protocol for systematic review and meta-analysis

Background:Although home-based pulmonary rehabilitation programs have been shown in some studies to be an alternative and effective model, there is a lack of consensus in the medical literature due to different study designs and lack of standardization among procedures. Therefore, the purpose of this study was to compare the efficacy of a home-based versus outpatient pulmonary rehabilitation program for patients with chronic obstructive pulmonary disease (COPD).Methods:Five electronic databases including Embase, PubMed, Scopus, Science Direct, and Cochrane Library will be searched in May 2021 by 2 independent reviewers. The reference lists of the included studies will be also checked for additional studies that are not identified with the database search. There is no restriction on the dates of publication or language in the search. The randomized controlled trials focusing on comparing home-based and outpatient pulmonary rehabilitation for COPD patients will be included in our meta-analysis. The following outcomes should have been measured: functional exercise capacity, disease-specific health-related quality of life, and cost-effectiveness measures. Risk ratio with a 95% confidence interval or standardized mean difference with 95% CI is assessed for dichotomous outcomes or continuous outcomes, respectively.Results:It was hypothesized that these 2 methods would provide similar therapeutic benefits.Registration number:10.17605/OSF.IO/5CV48.

Pulmonary rehabilitation in patients with chronic obstructive pulmonary disease

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality in India. Drug treatment alone does not optimize therapy. Pulmonary rehabilitation has been found to improve the physical efficiency of COPD patients. Therefore, we evaluated the effect of domiciliary pulmonary rehabilitation programme in patients of COPD. METHODS: Forty patients of stable COPD having severe airflow obstruction were included in the study. They were divided into control and experimental groups randomly. Rehabilitation included walking, breathing exercises, postural drainage, controlled coughing and changes in life style activities. Exercises of 30 minutes duration were performed at home twice daily for four weeks supervision. Six-minute walking distance, forced expiratory volume in one seocond (FEV1) and various indices of chronic respiratory disease questionnaire (CRDQ) were measured in both experimental and control groups before and after completion of the study. RESULTS: In the experimental group, after four weeks, the mean (+/- SD) difference in six-minute walking distance, dyspnoea, mastery, fatigue and emotion scores were 54.2 (26.7) meters, 0.96 (0.26), 0.89 (0.44), 0.90 (0.40) and 0.91 (0.32) respectively. Changes in all these parameters were statistically significant (p < 0.001) as compared to the control group. There was no significant change in FEV1. CONCLUSION: It was concluded that domiciliary pulmonary rehabilitation for four weeks results in significant improvement in the quality of life and exercise tolerance, even without improvement in FEV1.     

Success in pulmonary rehabilitation in patients with chronic obstructive pulmonary disease

BACKGROUND:

Pulmonary rehabilitation (PR) is beneficial for some, but not all, patients with chronic lung disease.

OBJECTIVES:

To determine the success rate of a comprehensive PR program for patients with chronic obstructive pulmonary disease (COPD) and to characterize the differences between responders and nonresponders.

METHODS:

A chart review was performed on patients with a clinical diagnosis of COPD who were referred for PR. Success was defined according to clinically important changes in St George’s Respiratory Questionnaire scores and/or 6 min walk test distance.

RESULTS:

The majority of subjects were men (58%) with a mean (± SD) age of 69±10 years (n=177). Sixty-two per cent of participants had a successful outcome with PR, with proportionally more responders noting subjective improvement than objective improvement on a 6 min walk test (73% versus 51%). Subjects with poor baseline St George’s Respiratory Questionnaire scores tended to improve the most (P=0.011 [ANOVA]). Successful participants had a greater forced expired volume in 1 s (1.1 L versus 0.9 L; P<0.05) and a lower BODE index (body mass index, airflow obstruction, dyspnea, and exercise capacity index) at baseline (9.6 versus 10.3; P<0.05). Success of PR was not correlated with age, sex, chronic hypoxemic respiratory failure or other chronic conditions. Successful participants were more likely to be compliant and to experience fewer adverse events (P≤0.001).

CONCLUSIONS:

Our study reinforced the belief that the majority of participants with COPD benefit from PR. Few baseline characteristics were predictive of success. Subjectively measured improvement occurred more frequently than objectively measured improvement and was greatest in those with the poorest baseline values.

Effects of high-intensity exercise training in a pulmonary rehabilitation programme for patients with chronic obstructive pulmonary disease

BACKGROUND AND OBJECTIVES: The benefits of pulmonary rehabilitation for patients with COPD depend on the intensity of training. Traditional pulmonary rehabilitation programmes (PRPs) do not consistently achieve high-intensity training and have variable training effects. This study examined the effects of high-intensity exercise training on cardiac and pulmonary function in COPD patients. METHODS: Patients with COPD participated in a 6-week, cardiopulmonary exercise test-based PRP. Spirometry, 6-min walking distance and cardiopulmonary exercise test were used to evaluate cardiopulmonary function, respiratory muscle strength and endurance at rest, during exercise and before and after the programme. Patients were encouraged to complete high-intensity exercise with a targeted training intensity of at least 75% maximum oxygen uptake (VO(2)). RESULTS: Thirty-four COPD patients were enrolled into the study; 16 completed the high-intensity training, 18 did not. At the end of the 12-session PRP, submaximal exercise capacity (6-min walking distance, 461.8 +/- 77.2-502.7 +/- 66.9 m, P < 0.001) improved in both the patients who completed high-intensity training and those who did not. Only the patients who completed high-intensity training had significant improvements in FVC (2.47 +/- 0.70-2.70 +/- 0.62 L, P = 0.024) at rest, maximal exercise capacity (peak VO(2), 1001.6 +/- 286.4-1116.1 +/- 320.4 mL/min, P = 0.020) and work efficiency (7.3 +/- 1.4-8.4 +/- 1.8 mL/min/watt, P = 0.026). There was no statistically significant difference between the two groups in the change in the physiological parameters before and after exercise. CONCLUSIONS: Exercise training in a PRP improved submaximal exercise capacity. Only patients who completed high-intensity exercise training showed improvements in maximal exercise capacity, FVC and work efficiency.     

Oxidative stress in chronic obstructive pulmonary disease patients submitted to a rehabilitation program

Pulmonary rehabilitation (PR) improves physical capacity and health quality in patients with chronic obstructive pulmonary disease (COPD). However, the effect of exercise on oxidative stress markers in COPD patients is only partially known. This study was designed to evaluate the oxidative stress response to long-term exercise in patients with COPD enrolled in a PR program. Fifteen COPD patients (FEV1 < 60%), age between 50 and 60 years, ex-smokers, were separated in two groups: exercise-trained (n=8) and sedentary group (n=7). Exercise consisted of an 8-week conditioning program using a cycle ergometer (three times a week, 1h session). An endurance test (60% of maximal load in an incremental cycle test) was performed before and after PR. Blood samples were obtained at baseline and immediately after each endurance test. We measured the index of lipid peroxidation, thiobarbituric acid reactive species (TBARS), total radical-trapping antioxidant parameter (TRAP) and xanthine oxidase (XO) activity. TRAP was significantly different between the exercise-trained group and sedentary group of COPD patients. Baseline TBARS values were increased after the exercise training program but decreased after the endurance test. XO decrease after effort in the trained and untrained groups. The results suggest that patients with COPD are characterized by increased systemic and pulmonary oxidative stress markers both at rest as well as induced by cardiopulmonary exercise test and that PR program was associated with decreased systemic exercise-induced oxidative damage.
