Effects of exercise-based pulmonary rehabilitation on severe/very severe COPD: a systematic review and meta-analysis.

ABSTRACT:

Objective

Pulmonary rehabilitation (PR) has been considered to be an effective treatment method for various respiratory diseases. However, the effects of exercise-based PR on patients with severe/very severe chronic obstructive pulmonary disease (COPD) are unclear. This review aimed to investigate the effects of exercise-based PR on patients with severe/very severe COPD.

Methods

PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov databases were searched from inception to December 23, 2022, without language restrictions. Randomized controlled trials (RCTs) investigating the effects of exercise-based PR on patients with severe/very severe COPD were included. Study selection, data extraction, and risk of bias assessment were conducted independently. RevMan software (version 5.3) was used for meta-analysis. The quality of evidence was rated using the Grading of Recommendations Assessment, Development and Evaluation system.

Results

Six studies (263 patients) were identified. Compared with the control group, the 6-min walking distance [MD = 52.91, 95% CI (3.80, 102.03)], the St. George's Respiratory Questionnaire total scores [MD = -7.70, 95% CI (-14.32, -1.08)] and the Borg scale scores [MD = -0.68, 95% CI (-1.28, -0.08)] in the experimental group improved, respectively. The St. George's Respiratory Questionnaire and Borg scale scores were rated as 'moderate quality' and 'low quality', respectively, and the 6-min walking distance was rated as 'very low quality'.

Conclusions

Exercise-based PR may improve the exercise capacity, quality of life and dyspnea of patients with severe/very severe COPD, which can be regarded as an adjuvant treatment. High quality and large sample RCTs are needed.

Project description:BackgroundPulmonary rehabilitation (PR) has been proposed as an effective method for many respiratory diseases. However, the effects of exercise-based PR on asthma are currently inconclusive. This review aimed to investigate the effects of exercise-based PR on adults with asthma.MethodsThe PubMed, Embase, Cochrane Library, Web of Science, International Clinical Trials Registry Platform and ClinicalTrials.gov databases were searched from inception to 31 July 2019 without language restriction. Randomized controlled trials (RCTs) investigating the effects of exercise-based PR on adults with asthma were included. Study selection, data extraction and risk of bias assessment were performed by two investigators independently. Meta-analysis was conducted by RevMan software (version 5.3). Evidence quality was rated by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system.ResultsTen literatures from nine studies (n = 418 patients) were identified. Asthma quality of life questionnaire total scores (MD = 0.39, 95% CI: 0.02 to 0.76) improved significantly in the experimental group compared to control group, including activity domain scores (MD = 0.58, 95% CI: 0.21 to 0.94), symptom domain scores (MD = 0.52, 95% CI: 0.19 to 0.85), emotion domain scores (MD = 0.53, 95% CI: - 0.03 to 1.09) and environment domain scores (MD = 0.56, 95% CI: 0.00 to 1.11). Both the 6-min walk distance (MD = 34.09, 95% CI: 2.51 to 65.66) and maximum oxygen uptake (MD = 4.45, 95% CI: 3.32 to 5.58) significantly improved. However, improvements in asthma control questionnaire scores (MD = - 0.25, 95% CI: - 0.51 to 0.02) and asthma symptom-free days (MD = 3.35, 95% CI: - 0.21 to 6.90) were not significant. Moreover, there was no significant improvement (MD = 0.10, 95% CI: - 0.08 to 0.29) in forced expiratory volume in 1 s. Nonetheless, improvements in forced vital capacity (MD = 0.23, 95% CI: 0.08 to 0.38) and peak expiratory flow (MD = 0.39, 95% CI: 0.21 to 0.57) were significant.ConclusionsExercise-based PR may improve quality of life, exercise tolerance and some aspects of pulmonary function in adults with asthma and can be considered a supplementary therapy. RCTs of high quality and large sample sizes are required.Clinical trial registrationThe review was registered with PROSPERO (The website is https://www.crd.york.ac.uk/prospero/ , and the ID is CRD42019147107).

Project description:Introduction: Oxidative stress is increasingly recognized as a significant factor in the pathogenesis of chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation, a major component of which is prescribed exercise, is essential in COPD care. Regular exercise has been proposed to increase antioxidant defenses and overall enhance the ability of the body to counteract oxidative stress. However, the mechanisms through which it improves COPD outcomes remain unclear. Objectives: We aimed to appraise the current evidence around the impact of pulmonary rehabilitation on redox status, compared with other exercise interventions, to gain an understanding of optimal exercise interventions to modify this pathophysiological mechanism. Methods: We performed a systematic review through searching CENTRAL, MEDLINE, PubMed, Scopus, and Web of Science. Results were independently reviewed and relevant studies were selected by two independent assessors. Studies were assessed by two independent people using the modified RoB 2 tool and discrepancies were resolved through discussion. Results: We identified 1,710 records and 1,117 records after duplicate removal. Six studies were included in the final analysis. The evidence available was low quality and four studies had high risk of bias and two studies had unclear risk of bias. Studies were small (15-56 participants); only two included details of randomization and patient cohorts were of varying ages and poorly described. Differences in smoking status and previous exercise levels, which are known to impact redox status, were not well documented. Studies were not standardized and used different exercise doses and measured different outcomes. One study reported lower malondialdehyde levels, a marker of lipid peroxidation, after pulmonary rehabilitation, compared with control. However, one study saw no difference following whole-body vibration training and another study showed higher malondialdehyde levels following supervised modified arm swing exercise compared with control. Conclusion: Understanding the impact of exercise on oxidative stress in COPD could lead to tailored exercise programs and modification of pathological mechanisms. However, we identify a lack of high-quality evidence to determine this. Larger, standardized, and high quality randomized controlled trials (RCTs) are essential, which use carefully clinically characterized and controlled cohorts to determine the relative impact of different exercise interventions on redox status to guide COPD management. We propose an idealized RCT design, which could be used to try and meet this need.

Project description:BackgroundPulmonary rehabilitation (PR), delivered as a supervised multidisciplinary program including exercise training, is one of the cornerstones in the chronic obstructive pulmonary disease (COPD) management. We performed a systematic review and meta-analysis to assess the effect on mortality of a supervised early PR program, initiated during or within 4 weeks after hospitalization with an acute exacerbation of COPD compared with usual post-exacerbation care or no PR program. Secondary outcomes were days in hospital, COPD related readmissions, health-related quality of life (HRQoL), exercise capacity (walking distance), activities of daily living (ADL), fall risk and drop-out rate.MethodsWe identified randomized trials through a systematic search using MEDLINE, EMBASE and Cocharne Library and other sources through October 2017. Risk of bias was assessed regarding randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases using the Cochrane Risk of Bias tool.ResultsWe included 13 randomized trials (801 participants). Our meta-analyses showed a clinically relevant reduction in mortality after early PR (4 trials, 319 patients; RR = 0.58 (95% CI: [0.35 to 0.98])) and at the longest follow-up (3 trials, 127 patients; RR = 0.55 (95% CI: [0.12 to 2.57])). Early PR reduced number of days in hospital by 4.27 days (1 trial, 180 patients; 95% CI: [- 6.85 to - 1.69]) and hospital readmissions (6 trials, 319 patients; RR = 0.47 (95% CI: [0.29 to 0.75])). Moreover, early PR improved HRQoL and walking distance, and did not affect drop-out rate. Several of the trials had unclear risk of bias in regard to the randomization and blinding, for some outcome there was also a lack of power.ConclusionModerate quality of evidence showed reductions in mortality, number of days in hospital and number of readmissions after early PR in patients hospitalized with a COPD exacerbation. Long-term effects on mortality were not statistically significant, but improvements in HRQoL and exercise capacity appeared to be maintained for at least 12 months. Therefore, we recommend early supervised PR to patients with COPD-related exacerbations. PR should be initiated during hospital admission or within 4 weeks after hospital discharge.

Project description:BackgroundPulmonary rehabilitation is an effective intervention for people with chronic obstructive pulmonary disease (COPD). People with COPD undertake repeat programs, but synthesis of evidence regarding such practice has not been undertaken. The aim of this systematic review was to establish the effects of repeating pulmonary rehabilitation subsequent to an initial program in people with COPD.MethodsStudies where participants with COPD undertook >1 pulmonary rehabilitation program were included, incorporating RCT (randomized controlled trial) and non-randomized studies. Electronic database searches were undertaken. Two authors independently undertook study identification, data extraction and risk of bias assessment. The primary outcome was health-related quality of life (HRQoL); secondary outcomes were exercise capacity, hospitalizations and exacerbations, adherence, mortality and adverse events. Narrative synthesis was undertaken for clinically heterogeneous trials. Data from RCTs and non-randomized studies were not combined for analysis.ResultsTen included studies (2 RCTs) involved 907 participants with COPD (n=653 had undertaken >1 program). The majority of studies were at high risk of bias. One RCT (n=33) reported no difference in HRQol after a repeat program vs usual care following exacerbation (Chronic Respiratory Disease Questionnaire dyspnea domain score MD 0.4, 95% CI -0.5 to 3). In stable patients, clinically important and statistically significant improvements in HRQoL and exercise capacity were reported after repeat programs, but of a smaller magnitude than initial programs. There was evidence for reductions in exacerbations and hospitalizations, and shorter hospital length of stay for patients who repeated a program twice in 12 months compared to those who repeated once. No data for mortality or adverse events were available.ConclusionThis systematic review provides limited evidence for benefits of repeating pulmonary rehabilitation in people with COPD, including improved HRQoL and exercise capacity, and reduced hospitalizations. However, most studies have high risk of bias, which reduces the certainty of these conclusions.Study registrationPROSPERO (CRD42020215093).

Project description:BackgroundPulmonary hypertension (PH) is a chronic progressive disease characterized by increasing pulmonary vascular resistance, poor prognosis and high disability rate. Although many targeted drugs for PH have been put to clinical use, most patients still have poor exercise tolerance and quality of life. Exercise training is considered to further improve exercise capacity and quality of life in patients with PH, but it has not been fully studied and utilized. The aim of this systematic review and meta-analysis is to evaluate the effectiveness and safety of exercise training in patients with PH.MethodsA search was conducted for the meta-analysis using the databases PubMed, Embase, Cochrane Library, including literature published before December 2018. The primary outcome of this meta-analysis was a change in the 6-minute walk distance (6MWD). In addition, peak oxygen uptake (PeakVO2), resting pulmonary arterial systolic pressure (PASPrest), resting heart rate (HRrest), peak exercise heart rate (HRpeak), oxygen uptake anaerobic threshold (VO2 at AT), maximum workload and quality of life (QoL) were also assessed.ResultsA total of 651 patients in 17 studies were included. A meta-analysis showed that exercise training was associated with significant improvement in the 6MWD [weighted mean difference (WMD): 64.75 m (95% CI: 53.19-76.31 m, P<0.001)], peakVO2 [WMD: 1.78 mL/min/kg (95% CI: 1.27-2.29 mL/min/kg, P<0.001)], HRpeak [WMD: 11.07 beats/min (95% CI: 8.04-14.11 beats/min, P<0.001)] and QoL measured by SF-36 questionnaire subscale scores. Furthermore, exercise training is well tolerated, and no major adverse event occurred related to exercise training.ConclusionsExercise training is associated with a significant improvement in exercise capacity, cardiorespiratory fitness and quality of life among patients with PH and proved to be safe for stable PH patients with optimization of medical therapy. However, more large-scale multicenter studies are needed to confirm the effectiveness and safety of exercise training in patients with PH.

Project description:Pulmonary rehabilitation (PR) reduces the number and duration of hospital admissions and readmissions, and improves health-related quality of life in patients with COPD. Despite clinical guideline recommendations, under-referral and limited uptake to PR contribute to poor treatment access. We reviewed published literature on the effectiveness of interventions to improve referral to and uptake of PR in patients with COPD when compared to standard care, alternative interventions, or no intervention. The review followed recognized methods. Search terms included "pulmonary rehabilitation" AND "referral" OR "uptake" applied to MEDLINE, EMBASE, CINAHL, PsycINFO, ASSIA, BNI, Web of Science, and Cochrane Library up to January 2018. Titles, abstracts, and full papers were reviewed independently and quality appraised. The protocol was registered (PROSPERO # 2016:CRD42016043762). We screened 5,328 references. Fourteen papers met the inclusion criteria. Ten assessed referral and five assessed uptake (46,146 patients, 409 clinicians, 82 hospital departments, 122 general practices). One was a systematic review which assessed uptake. Designs, interventions, and scope of studies were diverse, often part of multifaceted evidence-based management of COPD. Examples included computer-based prompts at practice nurse review, patient information, clinician education, and financial incentives. Four studies reported statistically significant improvements in referral (range 3.5%-36%). Two studies reported statistically significant increases in uptake (range 18%-21.5%). Most studies had methodological and reporting limitations. Meta-analysis was not conducted due to heterogeneity of study designs. This review demonstrates the range of approaches aimed at increasing referral and uptake to PR but identifies limited evidence of effectiveness due to the heterogeneity and limitations of study designs. Research using robust methods with clear descriptions of intervention, setting, and target population is required to optimize access to PR across a range of settings.
