Exercise prescription for hospitalized people with chronic obstructive pulmonary disease and comorbidities: a synthesis of systematic reviews

Musculoskeletal crosstalk in chronic obstructive pulmonary disease and comorbidities: Emerging roles and therapeutic potentials

Chronic Obstructive Pulmonary Disease (COPD) is a multifaceted respiratory disorder characterized by progressive airflow limitation and systemic implications. It has become increasingly apparent that COPD exerts its influence far beyond the respiratory system, extending its impact to various organ systems. Among these, the musculoskeletal system emerges as a central player in both the pathogenesis and management of COPD and its associated comorbidities. Muscle dysfunction and osteoporosis are prevalent musculoskeletal disorders in COPD patients, leading to a substantial decline in exercise capacity and overall health. These manifestations are influenced by systemic inflammation, oxidative stress, and hormonal imbalances, all hallmarks of COPD. Recent research has uncovered an intricate interplay between COPD and musculoskeletal comorbidities, suggesting that muscle and bone tissues may cross-communicate through the release of signalling molecules, known as "myokines" and "osteokines". We explored this dynamic relationship, with a particular focus on the role of the immune system in mediating the cross-communication between muscle and bone in COPD. Moreover, we delved into existing and emerging therapeutic strategies for managing musculoskeletal disorders in COPD. It underscores the development of personalized treatment approaches that target both the respiratory and musculoskeletal aspects of COPD, offering the promise of improved well-being and quality of life for individuals grappling with this complex condition. This comprehensive review underscores the significance of recognizing the profound impact of COPD on the musculoskeletal system and its comorbidities. By unravelling the intricate connections between these systems and exploring innovative treatment avenues, we can aspire to enhance the overall care and outcomes for COPD patients, ultimately offering hope for improved health and well-being.

Combination of diaphragmatic breathing with therapeutic walking exercise to increase peak expiratory flow rate in asthma patients

Objective: This study aimed to determine the effect of combined diaphragmatic breathing and therapeutic walking exercise on peak expiratory flow in asthma patients.

Methods: The research design used a quasi-experiment nonequivalent pretest and posttest design. The research sample contained 38 respondents divided into intervention and control groups, selected by simple random sampling. The control group received standard drug therapy, while the intervention group received standard drug therapy and a combination of diaphragmatic breathing and therapeutic walking exercise for 2 weeks. This exercise was carried out in the morning, 6 times a week, with 5 diaphragmatic breathing and exhalations per exercise. After that, a 1-min break was followed by a therapeutic walking exercise of 5–15 min, with an increased duration. Both groups measured the peak expiratory flow before and after the intervention using a peak flow meter. The data analysis used central tendency and t-test.

Results: The results showed that the mean peak expiratory flow in the intervention group was 306.84, while in the control group, it was 232.63, with the value of the t-test being −14.17 (P < 0.0001).

Conclusions: Diaphragmatic breathing and therapeutic walking exercise significantly increased the peak expiratory flow in asthma patients.

Osteoporosis in COPD patients: Risk factors and pulmonary rehabilitation

Objectives

To present a review on the pathogenesis, risk factor and treatment of chronic obstructive pulmonary disease complicated with osteoporosis and provide new ideas for the diagnosis and treatment.

Data source

A systematic search is carried out using keywords as chronic obstructive pulmonary disease, osteoporosis, risk factors, and pulmonary rehabilitation.

Results

Patients with chronic obstructive pulmonary disease have a high prevalence of osteoporosis and a high risk of fracture. The mechanisms of osteoporosis in COPD patients are associated with general risk factors, such as smoking, reduced physical activity, low weight, and disease‐specific risk factors, such as systemic inflammatory, Vitamin D deficiency, use of glucocorticoid, anemia, hypoxemia, and hypercapnia. The treatment of osteoporosis in COPD emphasizes comprehensive intervention, which mainly include basic treatment and anti‐osteoporosis drugs. Noticeably, pulmonary rehabilitation program is an important part of treatment.

Conclusions

This work summarizes the pathogenesis, risk factor, prevention, and treatment of chronic obstructive pulmonary disease complicated with osteoporosis, and the latest progress of studies on chronic obstructive pulmonary disease and osteoporosis is discussed.

Pulmonary Rehabilitation Programmes Within Three Days of Hospitalization for Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis

Objective

To evaluate the efficacy and safety of early pulmonary rehabilitation (PR) (ie, <3 days of hospitalization) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods

Embase, Web of Science, PubMed and Cochrane Library were searched from their inception to 1 April 2021. Randomized controlled trials were included if they observed the efficacy of early PR in AECOPD patients. Study selection, data extraction, risk of bias and quality of evidence were assessed by two researchers independently. Assessment of the risk of bias and eidence quality were evaluated by the Cochrane Collaboration’s tool and Grading of Recommendations, Assessment, Development and Evaluation system, respectively.

Results

Fourteen trials (829 participants) were identified. Significant improvement was found in the 6-minute walk distance (6MWD; mean difference (MD): 69.64; 95% CI: 40.26 to 99.01; Z = 4.65, P < 0.0001, low quality). In the subgroup analysis, the exercise-training group showed marked improvement (MD: 96.14; 95% CI: 20.24 to 172.04; Z = 2.48, P = 0.001). The Saint George’s Respiratory Questionnaire (SGRQ) total score was low (MD: −12.77; 95% CI: −16.03 to −9.50; Z = 7.67, P < 0.0001, moderate quality). Significant effects were not found for the duration of hospital stay, quadriceps muscle strength or five times sit to stand test. Only one serious adverse event was reported in experimental group, which was not associated with early PR.

Conclusion

PR initiated <3 days of hospitalization may increase exercise capacity and improve quality of life, but the results should be interpreted prudently and dialectically, and the role of early PR in AECOPD needs further exploration.

Physical exercise during acute exacerbations of chronic obstructive pulmonary disease: Australian physiotherapy practice

Evidence supports an important role for pulmonary rehabilitation (PR) after acute exacerbations of chronic obstructive pulmonary disease (AECOPD); however, the role of physical exercise during hospitalisation is less clear. This study evaluated Australian physiotherapy practice and clinical perspectives regarding exercise and physical activity for patients with AECOPD. A national survey of 123 Australian public hospitals was conducted from 2016 to 2017 using a purpose-designed survey measuring self-reported physical exercise prescription, objective measure use, referral patterns and factors influencing service delivery. The response rate was 72% (88 hospitals; 176 physiotherapists). Most physiotherapists (92%) prescribed physical exercise frequently for patients with AECOPD and perceived their role to be important (81%). The most commonly prescribed modalities were ground walking (94%), sit-to-stand (89%) and non-equipment-based lower limb strengthening (79%). Only 32% of respondents offered physiotherapy evaluation during post-discharge outpatient clinic appointments at their hospital. While 71% of respondents indicated they frequently referred patients to PR after AECOPD, rates were significantly higher in those with more cardiorespiratory experience (82%) than those with less experience (66%; p = 0.026). Australian physiotherapists frequently prescribe simple physical exercise modalities for patients with AECOPD. PR referral rates appear influenced by clinician experience, which may need consideration in future remedial strategies.

REABILITAÇÃO DOMICILIAR COM EXERCÍCIO NÃO SUPERVISIONADO NA DPOC: REVISÃO SISTEMÁTICA

RESUMO O objetivo desta revisão sistemática foi verificar os efeitos de programas de reabilitação pulmonar com exercícios domiciliares não supervisionados em pacientes com doença pulmonar obstrutiva crônica (DPOC), uma vez que a baixa disponibilidade de centros especializados no país, alto custo e outros fatores fazem com que poucos doentes tenham acesso a programas de reabilitação supervisionados em ambiente ambulatorial. Foram selecionados pelos autores oito ensaios clínicos controlados e randomizados que atendiam aos critérios de inclusão, atingiram pontuação mínima de cinco pontos na escala PEDro, publicados até novembro de 2014 na base de dados PubMed. Cinco desses trabalhos compararam um grupo de reabilitação domiciliar não supervisionado (GRNS) com um controle sem exercício (GC) e três compararam GRNS com um grupo que participou de reabilitação supervisionada (GRS) como controle. Os principais desfechos avaliados foram: capacidade funcional, função pulmonar, dispneia e qualidade de vida. De acordo com a análise realizada foi possível demonstrar que o treinamento não supervisionado em ambiente domiciliar ou na comunidade pode ser uma alternativa para pacientes estáveis com DPOC moderada à grave, visando sobretudo os benefícios relacionados à qualidade de vida e à dispneia; não foi possível verificar melhora em outros desfechos. Além disso, parece que esta forma de reabilitação no tratamento desses pacientes é segura e viável, porém mais estudos são necessários para averiguar os efeitos do treinamento automonitorado em outros desfechos.

Inpatient rehabilitation improves functional capacity, peripheral muscle strength and quality of life in patients with community-acquired pneumonia: a randomised trial

QUESTION

Among people who are hospitalised for community-acquired pneumonia, does an inpatient exercise-based rehabilitation program improve functional outcomes, symptoms, quality of life and length of hospital stay more than a respiratory physiotherapy regimen?

DESIGN

Randomised trial with concealed allocation, intention-to-treat analysis and blinding of some outcomes.

PARTICIPANTS

Forty-nine adults hospitalised for community-acquired pneumonia.

INTERVENTION

The experimental group (n=32) underwent a physical training program that included warm-up, stretching, peripheral muscle strength training and walking at a controlled speed for 15 minutes. The control group (n=17) underwent a respiratory physiotherapy regimen that included percussion, vibrocompression, respiratory exercises and free walking. The intervention regimens lasted 8 days.

OUTCOME MEASURES

The primary outcome was the Glittre Activities of Daily Living test, which assesses the time taken to complete a series of functional tasks (eg, rising from a chair, walking, stairs, lifting and bending). Secondary outcomes were distance walked in the incremental shuttle walk test, peripheral muscle strength, quality of life, dyspnoea, lung function, C-reactive protein and length of hospital stay. Measures were taken 1 day before and 1 day after the intervention period.

RESULTS

There was greater improvement in the experimental group than in the control group on the Glittre Activities of Daily Living test (mean between-group difference 39 seconds, 95% CI 20 to 59) and the incremental shuttle walk test (mean between-group difference 130 m, 95% CI 77 to 182). There were also significantly greater improvements in quality of life, dyspnoea and peripheral muscle strength in the experimental group than in the control group. There were no between-group differences in lung function, C-reactive protein or length of hospital stay.

CONCLUSION

The improvement in functional outcomes after an inpatient rehabilitation program was greater than the improvement after standard respiratory physiotherapy. The exercise training program led to greater benefits in functional capacity, peripheral muscle strength, dyspnoea and quality of life.

COPD and osteoporosis: links, risks, and treatment challenges

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory airway disease associated with various systemic comorbidities including osteoporosis. Osteoporosis and its related fractures are common and have significant impacts on quality of life and even respiratory function in patients with COPD. COPD-associated osteoporosis is however extremely undertreated. Recent studies have suggested that both decreased bone mineral density (BMD) and impaired bone quality contribute to bone fragility, causing fractures in COPD patients. Various clinical risk factors of osteoporosis in COPD patients, including older age, emaciation, physical inactivity, and vitamin D deficiency, have also been described. It is critically important for pulmonologists to be aware of the high prevalence of osteoporosis in COPD patients and evaluate them for such fracture risks. Routine screening for osteoporosis will enable physicians to diagnose COPD patients with comorbid osteoporosis at an early stage and give them appropriate treatment to prevent fracture, which may lead to improved quality of life as well as better long-term prognosis.

Clinical Decision-Making Tool for Safe and Effective Prescription of Exercise in Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Results From an Interdisciplinary Delphi Survey and Focus Groups

BACKGROUND

Exercise is recommended for people with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD), yet there is little information to guide safe and effective mobilization and exercise for these patients.

OBJECTIVES

The purpose of this study was to develop a clinical decision-making tool to guide health care professionals in the assessment, prescription, monitoring, and progression of mobilization and therapeutic exercise for patients with AECOPD.

DESIGN AND METHODS

A 3-round interdisciplinary Delphi panel identified and selected items based on a preselected consensus of 80%. These items were summarized in a paper-based tool titled Mobilization in Acute Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPD-Mob). Focus groups and questionnaires were subsequently used to conduct a sensibility evaluation of the tool.

RESULTS

Nine researchers, 13 clinicians, and 7 individuals with COPD identified and approved 110 parameters for safe and effective exercise in AECOPD. These parameters were grouped into 5 categories: (1) "What to Assess Prior to Mobilization," (2) "When to Consider Not Mobilizing or to Discontinue Mobilization," (3) "What to Monitor During Mobilization for Patient Safety," (4) "How to Progress Mobilization to Enhance Effectiveness," and (5) "What to Confirm Prior to Discharge." The tool was evaluated in 4 focus groups of 18 health care professionals, 90% of whom reported the tool was easy to use, was concise, and would guide a health care professional who is new to the acute care setting and working with patients with AECOPD.

LIMITATIONS

The tool was developed based on published evidence and expert opinion, so the applicability of the items to patients in all settings cannot be guaranteed. The Delphi panel consisted of health care professionals from Canada, so items may not be generalizable to other jurisdictions.

CONCLUSIONS

The AECOPD-Mob provides practical and concise information on safe and effective exercise for the AECOPD population for use by the new graduate or novice acute care practitioner.

Hospital management of acute exacerbations of chronic obstructive pulmonary disease

The course of chronic obstructive pulmonary disease (COPD) is often complicated by episodes of acute worsening of respiratory symptoms, which may lead to escalation of therapy and occasionally emergency department visits and hospitalization. Acute exacerbations of COPD (AECOPD) have a negative impact on quality of life and hasten the decline of lung function. They also significantly contribute to the direct and indirect healthcare costs of this disease. Severe exacerbations (those leading to hospital admission) have been associated with significant poor outcomes including an increased risk of readmissions and mortality. COPD is currently the fourth leading cause of hospital readmission in the United States. In this review, we will provide a broad overview on the etiology, assessment, management, discharge planning, and follow-up care of patients hospitalized with AECOPD.

Rising Costs of COPD and the Potential for Maintenance Therapy to Slow the Trend

BACKGROUND

Chronic obstructive pulmonary disease (COPD) affects an estimated 14% of adults in the United States between the ages of 40 and 79 years. This progressive disease is characterized by persistent airflow limitation. The management of patients with COPD is focused on reducing risk factors, relieving symptoms, and preventing exacerbations.

OBJECTIVE

To examine the peer-reviewed literature on the impact of maintenance therapy on the direct treatment costs of patients with COPD in the United States.

METHODS

PubMed was searched for articles written in English that were published between 2000 and 2013, using the search terms "COPD," "economics," "exacerbation," "maintenance," and related terms. Articles reporting the results of longitudinal studies of the costs associated with the management of patients with COPD, the costs associated with hospitalizations for acute exacerbations of COPD, and randomized clinical trials evaluating the effects of maintenance therapy on the incidence of COPD exacerbations were included in this review.

RESULTS

The search identified a total of 277 articles, and 11 of these articles were deemed appropriate for inclusion in this review. The direct healthcare costs for patients with COPD increased by 38% between 1987 and 2007, and continued to increase by approximately 5% annually between 2006 and 2009. The costs associated with hospital admissions for patients with COPD accounted for the largest absolute increase ($2289 per admission in constant 2007 US dollars). Recent estimates suggest that the aggregate costs associated with the treatment of acute exacerbations are between $3.2 billion and $3.8 billion, and that annual healthcare costs are 10-fold greater for patients with COPD associated with acute exacerbations than for patients with COPD but without exacerbations. The results of 2 large clinical trials of maintenance therapy, including a long-acting cholinergic antagonist or a long-acting beta-2 agonist, showed a 16% to 17% reduction in the incidence of exacerbations compared with placebo. Nevertheless, maintenance therapy remains underutilized, with only 30% to 35% of patients with COPD in private and public health insurance plans receiving prescriptions for maintenance therapy.

CONCLUSIONS

The treatment of acute exacerbations of COPD remains the major driver of increasing healthcare costs associated with this condition. The appropriate use of maintenance therapy has been shown to reduce the incidence of exacerbations and has the potential to reduce overall costs associated with the management of patients with COPD.

Safe and effective prescription of exercise in acute exacerbations of chronic obstructive pulmonary disease: rationale and methods for an integrated knowledge translation study

BACKGROUND

Patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) engage in low levels of activity, putting them at risk for relapse and future readmissions. There is little direction for health care providers regarding the parameters for safe exercise during an AECOPD that is effective for increasing activity tolerance before discharge from hospital, especially for patients with associated comorbid conditions.

OBJECTIVE

To report the rationale for and methods of a study to develop evidence-informed care recommendations that guide health care providers in the assessment, prescription, monitoring and progression of exercise for patients hospitalized with AECOPD.

METHODS

The present study was a multicomponent knowledge translation project incorporating evidence from systematic reviews of exercise involving populations with chronic obstructive pulmonary disease and⁄or common comorbidities. A Delphi process was then used to obtain expert opinion from clinicians, academics and patients to identify the parameters of safe and effective exercise for patients with AECOPD.

RESULTS

Clinical decision-making tool(s) for patients and practitioners supported by a detailed knowledge dissemination, implementation and evaluation framework.

CONCLUSION

The present study addressed an important knowledge gap: the lack of availability of parameters to guide safe and effective exercise prescription for hospitalized patients with AECOPD, with or without comorbid conditions. In the absence of such parameters, health care professionals may adopt an 'activity as tolerated' approach, which may not improve physical activity levels in their patients. The present study synthesizes the best available evidence and expert opinion, and will generate decision-making tools for use by patients and their health care providers.

Barriers to and enablers of physical activity in patients with COPD following a hospital admission: a qualitative study

Background

Chronic obstructive pulmonary disease (COPD) is characterized by a persistent blockage of airflow, prompting episodes of shortness of breath, commonly leading to hospitalization. Hospitalization may lead to a decline in physical activity following discharge. Physical activity has been shown to improve symptoms of COPD and reduce readmissions, and to decrease morbidity and mortality. This study aims to explore, from the perspectives of people with COPD, the barriers to and enablers of participation in physical activity following hospitalization for COPD.

Methods

This study had a qualitative descriptive design and included semistructured interviews with 28 adult COPD patients who had been admitted to hospital with a primary diagnosis of exacerbation of COPD.

Results

A plethora of barriers to but fewer enablers of participation in physical activity and pulmonary rehabilitation were identified for this cohort of people. The main barriers identified were health-related (comorbidities, COPD symptoms, and physical injury or illness) environment-related (weather, transport, and finance), and self-related. The main enabling factors reported were access to health professionals and equipment, social support, routine and extracurricular activities, personal goals and motivation, and the effect of physical activity and “feeling better”.

Conclusion

This research provides a snapshot of the barriers to and enablers of physical activity and pulmonary rehabilitation in people with COPD. It is evident that there are significant barriers which hinder the ability of people with COPD to undertake and continue participation in physical activity and pulmonary rehabilitation. While there are some enablers that may counter these barriers, it is clear that health professionals dealing with people suffering from COPD need to actively recognize and address barriers to physical activity and pulmonary rehabilitation. Hospital admission may create an opportunity for implementation of interventions promoting physical activity (such as referral to pulmonary rehabilitation), which may assist in reducing hospital readmission, as well as decreasing morbidity and mortality.

Pulmonary rehabilitation

Pulmonary rehabilitation is a therapy that offers benefits to patients with chronic obstructive pulmonary disease that are complementary to those obtained by pharmacotherapy. The main objective of pulmonary rehabilitation is to restore muscle function and exercise tolerance, reverse other nonrespiratory consequences of the disease, and help patients to self-manage chronic obstructive pulmonary disease and its exacerbations and symptoms. To do so, a multidisciplinary program tailored to the patient in terms of program content, exercise prescription, and setting must be offered. Several settings and programs have shown to spin off in significant immediate results. The challenge lies in maintaining the benefits outside the program.

Exercise training modalities and strategies to improve exercise performance in patients with respiratory disease

Pulmonary rehabilitation is an evidence-based, multidisciplinary, comprehensive intervention for patients with chronic respiratory diseases who are symptomatic and whose daily living activities are often restricted. Pulmonary rehabilitation programs are designed to improve the physical and emotional condition of people with chronic respiratory disease and to promote long-term adherence to health-enhancing behavior. Exercise training is at the core of pulmonary rehabilitation (PR) programs. The benefits of exercise training include decreased dyspnea, improved health-related quality of life, fewer days of hospitalization, and decreased health-care utilization. To gain PR benefits, patients should be able to complete an exercise training program, preferably with high intensity exercise, and it is likely that these benefits will translate into a change from a pattern of a sedentary lifestyle to a physically active lifestyle. Chronic respiratory patients, namely COPD patients, have a low exercise tolerance due to multiple factors, such as dynamic hyperinflation and peripheral muscle dysfunction. In this article, the authors describe a variety of modalities and strategies to overcome exercise limitations and improve the effects of exercise training.

Helping COPD patients change health behavior in order to improve their quality of life

Chronic obstructive pulmonary disease (COPD) is one of the most prevalent and debilitating diseases in adults worldwide and is associated with a deleterious effect on the quality of life of affected patients. Although it remains one of the leading causes of global mortality, the prognosis seems to have improved in recent years. Even so, the number of patients with COPD and multiple comorbidities has risen, hindering their management and highlighting the need for futures changes in the model of care. Together with standard medical treatment and therapy adherence--essential to optimizing disease control--several nonpharmacological therapies have proven useful in the management of these patients, improving their health-related quality of life (HRQoL) regardless of lung function parameters. Among these are improved diagnosis and treatment of comorbidities, prevention of COPD exacerbations, and greater attention to physical disability related to hospitalization. Pulmonary rehabilitation reduces symptoms, optimizes functional status, improves activity and daily function, and restores the highest level of independent physical function in these patients, thereby improving HRQoL even more than pharmacological treatment. Greater physical activity is significantly correlated with improvement of dyspnea, HRQoL, and mobility, along with a decrease in the loss of lung function. Nutritional support in malnourished COPD patients improves exercise capacity, while smoking cessation slows disease progression and increases HRQoL. Other treatments such as psychological and behavioral therapies have proven useful in the treatment of depression and anxiety, both of which are frequent in these patients. More recently, telehealthcare has been associated with improved quality of life and a reduction in exacerbations in some patients. A more multidisciplinary approach and individualization of interventions will be essential in the near future.
