Systematic review of clinical effectiveness, components, and delivery of pulmonary rehabilitation in low-resource settings

Effectiveness of a home-based pulmonary rehabilitation maintenance programme: the Rehab2Life study protocol

Pulmonary rehabilitation (PR) is the bedrock of non-pharmacological treatment for people with COPD. Nonetheless, it is well described in the literature that unless the patient changes his behaviour, the benefits of PR programmes will decline in six to twelve months after finishing the programme. Therefore, maintenance programmes can address the problem of PR programmes' effect loss over time.Community care units can provide multidisciplinary care in the current Portuguese primary health care context. These units have an interdisciplinary team that aims to develop competencies in COPD patients to self-manage the disease.This study aims to test the effectiveness of a 12-month home-based PR programme (Rehab2Life) compared to usual care through a single-blind randomised controlled trial with two parallel groups. The Rehab2Life programme includes two distinct phases. The first is an 8-week PR programme delivered to both groups, and the second is a PR maintenance programme delivered to the intervention group after the initial eight weeks. The control group receive the usual care and regular appointments. The primary outcome is functional capacity, and secondary outcomes are dyspnea, Health-Related Quality of Life (HRQoL), number of exacerbations, symptoms burden, anxiety and depression symptoms, and physical activity.We expect to observe that the home-based PR programme brings clinically relevant benefits to the participants at the end of the first eight weeks and that, at 12 months after the maintenance phase of the programme, benefits are less dissipated than in the control group. We expect to identify the characteristics of the patients who benefit the most from home-based programmes.The trial was registered on 7 April 2022 at ClinicalTrials.gov (NCT05315505).

Interventions to prevent post-tuberculosis sequelae: a systematic review and meta-analysis

Background

Tuberculosis (TB) remains a global public health challenge, causing substantial mortality and morbidity. While TB treatment has made significant progress, it often leaves survivors with post-TB sequelae, resulting in long-term health issues. Current healthcare systems and guidelines lack comprehensive strategies to address post-TB sequelae, primarily due to insufficient evidence. This systematic review and meta-analysis aimed to identify effective interventions for preventing post-TB sequelae.

Methods

A systematic search was conducted across four databases including PubMed, SCOPUS, Web of Science, and Cochrane Central Register of Controlled Trials from inception to September 22, 2023. Eligible studies reported interventions designed to prevent post-TB sequelae were included. A random effect meta-analysis was conducted where applicable, and heterogeneity between studies was evaluated visually using forest plots and quantitatively using an index of heterogeneity (I2). This study is registered with PROSPERO (CRD42023464392).

Findings

From the 2525 unique records screened, 25 studies involving 10,592 participants were included. Different interventions were evaluated for different outcomes. However, only a few interventions were effective in preventing post-TB sequelae. Rehabilitation programs significantly improved lung function (Hedges's g = 0.21; 95% confidence interval (CI): 0.03, 0.39) and prevented neurological sequelae (relative risk (RR) = 0.10; 95% CI: 0.02, 0.42). Comprehensive interventions and cognitive-behavioural therapy significantly reduced the risk of mental health disorders among TB survivors (Hedges's g = -1.89; 95% CI: -3.77, -0.01). In contrast, interventions targeting post-TB liver sequelae, such as vitamin A and vitamin D supplementation and hepatoprotective agents, did not show significant reductions in sequelae (RR = 0.90; 95% CI: 0.52, 1.57). Moreover, adjunctive therapies did not show a significant effect in preventing post-TB neurological sequelae (RR = 0.62, 95% CI: 0.31, 1.24).

Interpretation

Rehabilitation programs prevented post-TB lung, neurologic and mental health sequelae, while adjuvant therapies and other interventions require further investigation.

Exploring the perceptions of patients with chronic respiratory diseases and their insights into pulmonary rehabilitation in Bangladesh

Background

Chronic respiratory diseases (CRDs) require holistic management which considers patients' preferences, appropriate pharmacotherapy, pulmonary rehabilitation, and integrated care. We aimed to understand the perceptions of people with CRDs about their condition and pulmonary rehabilitation in Bangladesh.

Methods

We conducted semi-structured interviews with a maximum variation sample of people with CRDs who had participated in a feasibility study of pulmonary rehabilitation in 2021/2022. A multidisciplinary team transcribed the interviews verbatim and analysed them in Bengali using a grounded theory approach.

Results

We interviewed 15 participants with chronic obstructive pulmonary disease, asthma, or post-tuberculosis. The analysis revealed three themes. The first encompassed understanding CRDs: Patients characterised their condition by the symptoms (e.g. 'Hapani' meaning 'breathlessness') rather than describing a disease entity. Some believed occupation, previous infection, or family history to be a cause. The second theme included perceptions of pulmonary rehabilitation: Exercise was counterintuitive, as it exacerbated the breathlessness symptom that defined their disease. Views varied, though many acknowledged the benefits after a few sessions. Even with home-based programmes, participants described practical barriers to finding time for the sessions and adopted strategies to overcome the challenges. The third theme focused on implementation: Participants highlighted the need for raising awareness of CRDs and the potential of pulmonary rehabilitation in the community, adapting to the local context, and establishing an accessible resourced service.

Conclusions

Understanding how patients and their communities perceive their condition and the barriers (both conceptual and logistical) to acceptance is the first step to embedding this highly effective intervention into routine health care services in Bangladesh with potential benefits for the increasing number of people living with CRDs in low- and middle-income countries.

Perspectives of Patients With Chronic Respiratory Diseases and Medical Professionals on Pulmonary Rehabilitation in Pune, India: Qualitative Analysis

BACKGROUND

Chronic respiratory diseases (CRDs) contribute significantly to morbidity and mortality worldwide and in India. Access to nonpharmacological options, such as pulmonary rehabilitation (PR), are, however, limited. Given the difference between need and availability, exploring PR, specifically remotely delivered PR, in a resource-poor setting, will help inform future work.

OBJECTIVE

This study explored the perceptions, experiences, needs, and challenges of patients with CRDs and the potential of and the need for PR from the perspective of patients as well as medical professionals involved in the referral (doctors) and delivery (physiotherapists) of PR.

METHODS

In-depth qualitative semistructured interviews were conducted among 20 individuals diagnosed with CRDs and 9 medical professionals. An inductive thematic analysis approach was used as we sought to identify the meanings shared both within and across the 2 participant groups.

RESULTS

The 20 patients considered lifestyle choices (smoking and drinking), a lack of physical activity, mental stress, and heredity as the triggering factors for their CRDs. All of them equated the disease with breathlessness and a lack of physical strength, consulting multiple doctors about their physical symptoms. The most commonly cited treatment choice was an inhaler. Most of them believed that yoga and exercise are good self-management strategies, and some were performing yoga postures and breathing exercises, as advised by friends or family members or learned from a televised program or YouTube videos. None of them identified with the term "pulmonary rehabilitation," but many were aware of the exercise component and its benefits. Despite being naive to smartphone technology or having difficulty in reading, most of them were enthusiastic about enrolling in an application-based remotely delivered digital PR program. The 9 medical professionals were, however, reluctant to depend on a PR program delivered entirely online. They recommended that patients with CRDs be supported by their family to use technology, with some time spent with a medical professional during the program.

CONCLUSIONS

Patients with CRDs in India currently manage their disease with nonguided strategies but are eager to improve and would benefit from a guided PR program to feel better. A home-based PR program, with delivery facilitated by digital solutions, would be welcomed by patients and health care professionals involved in their care, as it would reduce the need for travel, specialist equipment, and setup. However, low digital literacy, low resource availability, and a lack of expertise are of concern to health care professionals. For India, including yoga could be a way of making PR "culturally congruent" and more successful. The digital PR intervention should be flexible to individual patient needs and should be complemented with physical sessions and a feedback mechanism for both practitioners as well as patients for better uptake and adherence.

Health Equity and Respiratory Diseases in Low- and Middle-Income Countries

Over 80% of the morbidity and mortality related to acute and chronic respiratory diseases occur in low- and middle-income countries (LMICs), a reflection of vast disparities in care for these conditions. Over the next decade, the prevalence of respiratory diseases is expected to increase, as population growth in LMICs exceeds high-income countries (HICs). Pediatric morbidity and mortality from lower respiratory tract infections and asthma occur almost exclusively in LMICs, contributing to a greater loss of quality adjusted life years from these conditions when compared with HICs.

Needs assessment for introducing pulmonary rehabilitation for chronic obstructive pulmonary disease management in a rural Indian setting: a qualitative study

BACKGROUND

Pulmonary rehabilitation (PR) is an effective strategy to improve breathlessness, health status and exercise tolerance and to reduce readmissions and mortality. In India, there is no government health programme for chronic obstructive pulmonary disease (COPD) management while in the private sector availability of PR is limited. Most PR centres are in urban areas, with few services accessible to rural populations. We aimed to assess the need for PR from the perspective of patients with COPD and healthcare professionals (HCPs: registered medical practitioners and medical officers) in rural Maharashtra.

METHODOLOGY

Between June and October 2020, we conducted semi-structured interviews with 14 patients with COPD and 9 HCPs to explore their perceptions of, and need for, PR in rural Maharashtra. Interviews were transcribed and analysed thematically.

RESULTS

We approached 14 patients with COPD and 9 HCPs practising in rural areas. Five HCPs stated that they did not advise PR for patients with COPD citing poor compliance to PR referral and follow-up of the patients. Patients with COPD had symptoms and needs that could be helped by PR but commented how transportation would be a problem for them to visit a PR centre. In contrast, they could understand the benefits of PR and expressed their willingness to join such programmes. A PR service was established that addressed these needs.

CONCLUSION

Patients with COPD have unmet needs that could benefit from attending a PR programme, but there are barriers at both healthcare and patient levels that we addressed in a new PR service for people with chronic respiratory disease in rural Maharashtra.

Effectiveness of Nonpharmacological Interventions in the Field of Ventilation: An Umbrella Review

This umbrella review aimed to determine the effectiveness of nonpharmacological interventions in pulmonary ventilation and their impact on respiratory function. An individual with impaired ventilation displays visible variations manifested in their respiratory frequency, breathing rhythm ratio (I:E), thoracic symmetry, use of accessory muscles, dyspnea (feeling short of breath), oxygen saturation, diaphragm mobility, minute ventilation, peak flow, walking test, spirometry, Pimax/Pemax, diffusion, and respiratory muscle strength. Any variation in these markers demands the need for interventions in order to duly manage the signs and symptoms and to improve ventilation.

METHOD

Systematic reviews of the literature published in English, Spanish, French, and Portuguese were used, which included studies in which nonpharmacological interventions were used as a response to impaired ventilation in adults in any given context of the clinical practice. The recommendations given by the Joanna Briggs Institute (JBI) for umbrella reviews were followed. This research took place in several databases such as MEDLINE, CINAHL Complete, CINHAL, MedicLatina, ERIC, Cochrane Reviews (Embase), and PubMed. The Joanna Briggs critical analysis verification list was used for the systematic review. The data extraction was performed independently by two investigators based on the data extraction tools of the Joanna Briggs Institute, and the data were presented in a summary table alongside the support text.

RESULTS

Forty-four systematic reviews, thirty randomized clinical essays, and fourteen observational studies were included in this review. The number of participants varied between n = 103 and n = 13,370. Fifteen systematic revisions evaluated the effect of isolated respiratory muscular training; six systematic revisions evaluated, in isolation, breathing control (relaxed breathing, pursed-lip breathing, and diaphragmatic breathing exercises) and thoracic expansion exercises; and one systematic review evaluated, in isolation, the positions that optimize ventilation. Nineteen systematic reviews with combined interventions that reinforced the role of education and capacitation while also aiming for their success were considered. The articles analyzed isolated interventions and presented their efficacy. The interventions based on respiratory exercises and respiratory muscular training were the most common, and one article mentioned the efficacy of positioning in the compromisation of ventilation. Combined interventions in which the educational component was included were found to be effective in improving pulmonary function, diffusion, oxygenation, and functional capacity. The outcomes used in each study were variable, leading to a more difficult analysis of the data.

CONCLUSIONS

The interventions that were the focus of the review were duly mapped. The results suggest that nonpharmacological interventions used to optimize ventilation are effective, with a moderate to high level of evidence. There is a strong foundation for the use of the chosen interventions. The lack of studies on the intervention of "positioning to optimize ventilation" points out the need for a deeper analysis of its effects and for studies with a clear focus. This study supports the decisions and recommendations for the prescription of these interventions to patients with impaired ventilation.

Greater exercise tolerance in COPD during acute intermittent compared to continuous shuttle walking protocols: A proof-of-concept study

Objectives: Ground-based walking is a simple training modality which would suit pulmonary rehabilitation (PR) settings with limited access to specialist equipment. Patients with COPD are, however, unable to walk uninterruptedly at a relatively fast walking pace to optimise training benefits. We compared an intermittent (IntSW) to a continuous (CSW) shuttle walking protocol.Methods: In 14 COPD patients (mean ± SD. FEV₁: 45 ± 21% predicted) we measured walking distance, cardiac output (CO), arterial oxygen saturation (SpO₂), and symptoms during (a) an IntSW protocol, consisting of 1-min walking alternating with 1-min rest, and (b) a CSW protocol, both sustained at 85% of predicted VO₂ peak to the limit of tolerance (Tlim).Results: Median (IQR) distance was greater (p = 0.001) during the IntSW protocol (735 (375-1107) m) than the CSW protocol (190 (117-360) m). At iso-distance (distance at Tlim during CSW) the IntSW compared to the CSW protocol was associated with lower CO (8.6 ± 2.6 vs 10.3 ± 3.7 L/min; p = 0.013), greater SpO₂ (92 ± 6% versus 90 ± 7%; p = 0.002), and lower symptoms of dyspnoea (2.8 ± 1.3 vs 4.9 ± 1.4; p = 0.001) and leg discomfort (2.3 ± 1.7 vs 4.2 ± 2.2; p = 0.001). At Tlim symptoms of dyspnoea and leg discomfort did not differ between the IntSW (4.4 ± 1.9 and 3.6 ± 2.1, respectively) and the CSW protocol.Conclusions: The IntSW protocol may provide important clinical benefits during exercise training in the PR settings because it allows greater work outputs compared to the CSW.

The RECHARGE-IPCRG ‘Teach the Teacher’ programme: building capacity for pulmonary rehabilitation in low- and middle-income countries

Introduction

Chronic respiratory diseases are the most common causes of morbidity and mortality globally. Pulmonary rehabilitation (PR) is a low-cost, high-impact intervention with patient education and exercise at its core. Although supported by a well-established evidence base, demand greatly exceeds capacity in low- and middle-income countries (LMIC), including limited workforce training opportunities to support PR development and implementation. The International Primary Care Respiratory Group’s (IPCRG) Teach the Teacher (TtT) is an established education programme designed to build sustainable local clinical teaching and delivery capacity.

Methods

A collaboration between the National Institute for Health and Care Research (NIHR) funded Global RECHARGE Group for PR and IPCRG to deliver a ‘Teach the Teacher’ (TtT) programme for PR capacity building. Our Tier 1 TtT programme combined educational and PR service development concepts with core clinical content adapted for RECHARGE partners in India (Pune and Delhi), Sri Lanka, Kyrgyzstan and Uganda. Due to the severe acute respiratory syndrome coronavirus-2 (SARS‑CoV‑2) pandemic, the programme was adapted to a digital environment using online platforms such as Zoom video conferencing and Google Classroom. We used an adapted framework to evaluate professional learning and its impact.

Findings

Fifteen Tier 1/local leader participants attended a sixteen-hour online programme in September-October 2021. Participants included nurses, physiotherapists, doctors and early career health professionals/researchers. As local leaders in PR, participants created a tiered teaching programme for developing a critical mass of PR expert teachers, contextualised to their local healthcare systems and cultures. Participants also explored how to engage and influence multiple professional groups and stakeholders to support the widespread sustainable implementation of PR.

Conclusions

The RECHARGE-IPCRG TtT programme provided a clear education and service development framework to support PR capacity development in LMIC. We address a lack of empirical evidence concerning capacity-building initiatives by being explicit about the programme’s learning design, management and evaluation. A whole system perspective to PR allowed consideration of health systems, culture, referral pathways and scalability. Sustainable national PR education programmes will require additional resources and a long-term strategy, potentially aligning with the TtT three-tier cascade model.

Pharmacological, Nutritional, and Rehabilitative Interventions to Improve the Complex Management of Osteoporosis in Patients with Chronic Obstructive Pulmonary Disease: A Narrative Review

Osteoporosis is a highly prevalent condition affecting a growing number of patients affected by chronic obstructive pulmonary disease (COPD), with crucial implications for risk of fragility fractures, hospitalization, and mortality. Several risk factors have been identified to have a role in osteoporosis development in COPD patients, including corticosteroid therapy, systemic inflammation, smoke, physical activity levels, malnutrition, and sarcopenia. In this scenario, a personalized multitarget intervention focusing on the pathological mechanisms underpinning osteoporosis is mandatory to improve bone health in these frail patients. Specifically, physical exercise, nutritional approach, dietary supplements, and smoke cessation are the cornerstone of the lifestyle approach to osteoporosis in COPD patients, improving not only bone health but also physical performance and balance. On the other hand, pharmacological treatment should be considered for both the prevention and treatment of osteoporosis in patients at higher risk of fragility fractures. Despite these considerations, several barriers still affect the integration of a personalized approach to managing osteoporosis in COPD patients. However, digital innovation solutions and telemedicine might have a role in optimizing sustainable networking between hospital assistance and community settings to improve bone health and reduce sanitary costs of the long-term management of COPD patients with osteoporosis.

Effectiveness of home-based pulmonary rehabilitation: systematic review and meta-analysis

INTRODUCTION

Despite proven effectiveness for people with chronic respiratory diseases, practical barriers to attending centre-based pulmonary rehabilitation (centre-PR) limit accessibility. We aimed to review the clinical effectiveness, components and completion rates of home-based pulmonary rehabilitation (home-PR) compared to centre-PR or usual care.

METHODS AND ANALYSIS

Using Cochrane methodology, we searched (January 1990 to August 2021) six electronic databases using a PICOS (population, intervention, comparison, outcome, study type) search strategy, assessed Cochrane risk of bias, performed meta-analysis and narrative synthesis to answer our objectives and used the Grading of Recommendations, Assessment, Development and Evaluations framework to rate certainty of evidence.

RESULTS

We identified 16 studies (1800 COPD patients; 11 countries). The effects of home-PR on exercise capacity and/or health-related quality of life (HRQoL) were compared to either centre-PR (n=7) or usual care (n=8); one study used both comparators. Compared to usual care, home-PR significantly improved exercise capacity (standardised mean difference (SMD) 0.88, 95% CI 0.32-1.44; p=0.002) and HRQoL (SMD -0.62, 95% CI -0.88--0.36; p<0.001). Compared to centre-PR, home-PR showed no significant difference in exercise capacity (SMD -0.10, 95% CI -0.25-0.05; p=0.21) or HRQoL (SMD 0.01, 95% CI -0.15-0.17; p=0.87).

CONCLUSION

Home-PR is as effective as centre-PR in improving functional exercise capacity and quality of life compared to usual care, and is an option to enable access to pulmonary rehabilitation.

Feasibility of a pulmonary rehabilitation programme for patients with symptomatic chronic obstructive pulmonary disease in Georgia: a single-site, randomised controlled trial from the Breathe Well Group

OBJECTIVES

To assess the feasibility of delivering a culturally tailored pulmonary rehabilitation (PR) programme and conducting a definitive randomised controlled trial (RCT).

DESIGN

A two-arm, randomised feasibility trial with a mixed-methods process evaluation.

SETTING

Secondary care setting in Georgia, Europe.

PARTICIPANTS

People with symptomatic spirometry-confirmed chronic obstructive pulmonary disease recruited from primary and secondary care.

INTERVENTIONS

Participants were randomised in a 1:1 ratio to a control group or intervention comprising 16 twice-weekly group PR sessions tailored to the Georgian setting.

PRIMARY AND SECONDARY OUTCOME MEASURES

Feasibility of the intervention and RCT were assessed according to: study recruitment, consent and follow-up, intervention fidelity, adherence and acceptability, using questionnaires and measurements at baseline, programme end and 6 months, and through qualitative interviews.

RESULTS

The study recruited 60 participants (as planned): 54 (90%) were male, 10 (17%) had a forced expiratory volume in 1 second of ≤50% predicted. The mean MRC Dyspnoea Score was 3.3 (SD 0.5), and mean St George's Respiratory Questionnaire (SGRQ) 50.9 (SD 17.6). The rehabilitation specialists delivered the PR with fidelity. Thirteen (43.0%) participants attended at least 75% of the 16 planned sessions. Participants and rehabilitation specialists in the qualitative interviews reported that the programme was acceptable, but dropout rates were high in participants who lived outside Tbilisi and had to travel large distances. Outcome data were collected on 63.3% participants at 8 weeks and 88.0% participants at 6 months. Mean change in SGRQ total was -24.9 (95% CI -40.3 to -9.6) at programme end and -4.4 (95% CI -12.3 to 3.4) at 6 months follow-up for the intervention group and -0.5 (95% CI -8.1 to 7.0) and -8.1 (95% CI -16.5 to 0.3) for the usual care group at programme end and 6 months, respectively.

CONCLUSIONS

It was feasible to deliver the tailored PR intervention. Approaches to improve uptake and adherence warrant further research.

A feasibility trial of pulmonary rehabilitation for patients with COPD in a low resource setting: Jaffna, Sri Lanka

BACKGROUND

Pulmonary rehabilitation is recommended for most patients with chronic obstructive pulmonary disease (COPD). Accordingly, the aim of this study was to explore the feasibility of devising a pulmonary rehabilitation program for patients with COPD in a low resource setting (Jaffna, Sri Lanka) and to observe its effects.

METHODS

Non-randomized controlled feasibility trial of ambulatory patients with COPD attending the pulmonary outpatient clinic of the Jaffna Teaching Hospital, Northern Province, Sri Lanka. Age-matched patients were allocated alternatively to an intervention group or to a control group. Twice weekly, for six weeks, patients in the intervention group attended pulmonary rehabilitation sessions consisting of supervised stretching, aerobic and strengthening exercises, and patient-education. Before and at the conclusion of the study, all patients performed incremental shuttle walking test (ISWT), 6-min walk test (6MWT) and completed the Medical Research Council (MRC) dyspnea scale, COPD assessment test (CAT), chronic COPD questionnaire (CCQ), and hospital anxiety depression scale (HADS).

RESULTS

204 patients with COPD (94% males) were identified at screening; 136 (66.7%) were eligible for pulmonary rehabilitation and 96 patients (47%) consented to participate. Of these, 54 patients (53 males) eventually participated in the study (42 patients were discouraged to participate by family members or friends); 40 patients (20 in the rehabilitation group and 20 patients in the control group) completed the study. Baseline characteristics of the intervention group and the control group were similar. 95% of patients in the intervention group adhered to regular home training exercises (self-reported diary). At post assessment, only the intervention group experienced clinically-meaningful improvements in symptoms and exercise capacity.

CONCLUSION

A simple and clinically beneficial pulmonary rehabilitation program for patients with COPD can be effectively implemented in a low resource setting. However, there is a need for educating patients and the local community on the benefits of pulmonary rehabilitation to enhance uptake. Retrospective Trial Registration date and number: 16/04/2021, ISRCTN10069208.

Developing Appropriate Pulmonary Rehabilitation Services in Sri Lanka: Assessment of People Living with COPD and Healthcare Providers in Urban and Semi Urban Areas in Sri Lanka

Introduction

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, corresponding to 5% of all deaths globally, with more than 90% occurring in low- and middle-income countries (LMIC). Pulmonary Rehabilitation (PR) is a routine clinical service for COPD management, often used in western countries. At present, there is no formal PR in Sri Lanka; a culturally appropriate programme is required that considers the views of adults living with COPD and healthcare providers (HCPs) who would be involved in the referral or delivery of PR.

Purpose

The study assessed the attitudes and preferences of Sri Lankan adults living with COPD and attitudes and barriers of HCPs making PR referrals to inform an appropriate PR programme.

Methodology

A descriptive cross-sectional study was conducted with the ethical clearance of Colombo south teaching hospital ERC committee (ERC Application No. 674), among adults living with COPD and HCPs in Colombo district, Sri Lanka. Adults living with COPD were enrolled August 2018–December 2018 using systematic random sampling from Colombo South Teaching Hospital and were assessed using a pre-tested interviewer administered questionnaire. HCPs were recruited from Colombo South Teaching Hospital and Jaffna Teaching Hospital between August 2018 and November 2018 and assessed using self-administered questionnaire.

Results

Responses from 138 adults living with COPD (53% male, 52% aged ≥60 years) and 277 HCPs were collected. The majority of adults living with COPD were interested in participating in PR (80%) and would prefer PR to be delivered in a supervised, group-based, setting with hospital-based (49%). Adults living with COPD were mostly (73%) willing to spend between 30 minutes and 2 hours per day for PR-related activities. Among HCPs, 234 (83%) were nurses, 29 (11%) were hospital doctors and 14 (4%) were family physicians. The majority of HCPs stated that they were unsure about referring adults with COPD for PR (86%) and 61% stated considerable uncertainty regarding the availability of resources for PR. Nearly half of the HCPs (45%) felt they were not adequately prepared to refer adults living with COPD to PR programmes. Most HCPs (92%) reported that PR is worthwhile for COPD management.

Conclusion

Adults living with COPD in Sri Lanka are willing to attend PR and would prefer group-based programmes delivered in hospitals, under the supervision of qualified personnel. Awareness about PR is poor and there is a lack of readiness to refer to PR amongst HCPs. There is an urgent need to train HCPs on PR and develop effective referral strategies to support PR uptake and delivery for adults living with COPD in Sri Lanka.

“My life is not going to be the same, my health is going to improve”: a cross-sectional qualitative study of patients’ experiences of living with chronic respiratory symptoms and their views on a proposed pulmonary rehabilitation program at Queen Elizabeth Central Hospital, Blantyre, Malawi

Background: Malawi’s population has a substantial burden of chronic respiratory symptoms. Elsewhere, patients with these symptoms have benefited from pulmonary rehabilitation (PR), a program of exercise training, education, and behaviour management. Practically, PR in Malawi may not be delivered in the same format as elsewhere due to substantial contextual differences. These differences necessitate adaptation of the intervention to Malawi’s setting to be acceptable and effective. This study explored patients’ experiences of living with chronic respiratory symptoms and their views on a proposed PR program at Queen Elizabeth Central Hospital, Blantyre, Malawi, to inform the design of an individualized and culturally adapted PR program. Methods: This was a cross-sectional qualitative study. Face-to-face, one-to-one semi-structured in-depth interviews were undertaken to data saturation. Interviews were audio-recorded, transcribed verbatim, and Chichewa transcripts were translated into English. The transcripts were anonymized and thematically analysed using an inductive approach. Results: We recruited 10 patients (five males and five females) with functionally limiting chronic respiratory symptoms, with documented causes including chronic obstructive pulmonary disease, asthma, post-tuberculosis lung disease, and bronchiectasis. Symptoms most frequently included dyspnoea, with associated functional limitations including the reduced performance of activities of daily living. Participants’ coping strategies most frequently included the use of inhalers. Participants were motivated to undertake the PR program owing to its anticipated benefits including improved health. They perceived transport costs and competing commitments as barriers to participation. The participant group gender mix and public nature of the program were considered socio-culturally sensitive by some participants. Conclusions: The functionally limiting dyspnoea most frequently experienced by the study participants would be amenable to a PR program. To ensure participation by eligible patients, pre-program assessments should consider patient access to transport, suitability of the timing for the program’s sessions, and patient views on organizational aspects of the program considered social-culturally sensitive.

Protocol for a single-centre mixed-method pre-post single-arm feasibility trial of a culturally appropriate 6-week pulmonary rehabilitation programme among adults with functionally limiting chronic respiratory diseases in Malawi

INTRODUCTION

Malawi has a substantial burden of chronic respiratory diseases (CRDs) which cause significant morbidity and loss of economic productivity, affecting patients, families and health systems. Pulmonary rehabilitation (PR) is a highly recommended non-pharmacological intervention in the clinical management of people with CRDs. However, Malawi lacks published evidence on the implementation of PR for people with CRDs. This trial will test the feasibility and acceptability of implementing a culturally appropriate hospital-based PR programme among adults with functionally limiting CRDs at Queen Elizabeth Central Hospital in Blantyre, Malawi.

METHODS AND ANALYSIS

This is a single-centre mixed-methods pre-post single-arm feasibility trial. Ten patients aged ≥18 years, with a spirometry confirmed diagnosis of a CRD and breathlessness of ≥2 on the modified Medical Research Council dyspnoea scale, will be consecutively recruited. Their baseline lung function, exercise tolerance and health status will be assessed; including spirometry, Incremental Shuttle Walk Test and Chronic Obstructive Pulmonary Disease Assessment Test, respectively. Pretrial semistructured in-depth interviews will explore their experiences of living with CRD and potential enablers and barriers to their PR uptake. Along with international PR guidelines, these data will inform culturally appropriate delivery of PR. We initially propose a 6-week, twice-weekly, supervised centre-based PR programme, with an additional weekly home-based non-supervised session. Using combination of researcher observation, interaction with the participants, field notes and informal interviews with the participants, we will assess the feasibility of running the programme in the following areas: participants' recruitment, retention, engagement and protocol adherence. Following programme completion (after 6 weeks), repeat assessments of lung function, exercise tolerance and health status will be conducted. Quantitative changes in clinical outcomes will be described in relation to published minimal clinically important differences. Post-trial semistructured interviews will capture participants' perceived impact of the PR programme on their quality of life, enablers, and barriers to fully engaging with the programme, and allow iteration of its design.

ETHICS AND DISSEMINATION

Ethical approval for this trial was obtained from University of Malawi College of Medicine Research and Ethics Committee (COMREC), Blantyre, Malawi (protocol number: P.07/19/2752) and University of Leicester Research Ethics Committee, Leicester, UK (ethics reference: 31574). The results of the trial will be disseminated through oral presentations at local and international scientific conferences or seminars and publication in a peer-reviewed journal. We will also engage the participants who complete the PR trial and the Science Communication Department at Malawi-Liverpool-Wellcome Trust Clinical Research Programme to organise community outreach activities within Blantyre to educate communities about CRDs and PR. We will also broadcast our trial results through national radio station programmes such as the weekly "Thanzi la Onse" (Health of All) programme by Times Radio Malawi. We will formally present our trial results to Blantyre District Health Office and Malawi Ministry of Health.

Barriers and Enablers to Pulmonary Rehabilitation in Low- and Middle-Income Countries: A Qualitative Study of Healthcare Professionals

Introduction

Low- and middle-income countries bear a disproportionately high burden of global morbidity and mortality caused by chronic respiratory diseases. Pulmonary rehabilitation is recommended as a core intervention in the management of people with chronic respiratory diseases. However, the intervention remains poorly accessed/utilised globally, especially in low- and middle-income countries.

Aim

This qualitative study explored barriers and enablers to pulmonary rehabilitation in low- and middle-income countries from the perspective of healthcare professionals with pulmonary rehabilitation experience in these settings.

Methods

Online-based semi-structured in-depth interviews with healthcare professionals were undertaken to data saturation, exploring lived barriers and enablers to pulmonary rehabilitation in their low- or middle-income country. Anonymised interviews were audio-recorded, transcribed verbatim, and analysed using thematic analysis.

Results

A total of seven healthcare professionals from seven low- and middle-income countries representing Africa, Asia, and South America were interviewed. They included five physiotherapists (four females), one family physician (male), and one pulmonologist (female). Themes for barriers to pulmonary rehabilitation included limited resources, low awareness, coronavirus disease 2019, and patient access-related costs. Themes for enablers included local adaptation, motivated patients, coronavirus disease 2019 (which spanned both enablers and barriers), better awareness/recognition, provision of PR training, and resource support.

Conclusion

Barriers to pulmonary rehabilitation in low- and middle-income countries include limited resources, low awareness, coronavirus disease 2019, and patient access-related costs. Enablers include local adaptation, motivated patients, coronavirus disease 2019 (which spanned both enablers and barriers), better awareness/recognition, provision of PR training, and resource support. Successful implementation of these enablers will require engagement with multiple stakeholders. The findings of this study are a necessary step towards developing strategies that can overcome the existing pulmonary rehabilitation evidence-practice gap in low- and middle-income countries and alleviating the burden of chronic respiratory diseases in these countries.

Application of pulmonary rehabilitation in patients with pulmonary embolism (Review)

As a common clinical emergency, pulmonary embolism (PE) is the third most fatal cardiovascular disease worldwide. Although current sophisticated medical technology has considerably improved the prognosis of patients with PE, they remain at risk of developing long-term complications such as post-PE syndrome. Pulmonary rehabilitation is of great value for patients with chronic lung diseases since it can improve their quality of life while also relieving clinical symptoms. Rehabilitation therapy has been demonstrated to improve recovery and prognosis of patients with PE. Due to short implementation time and the small number of studies, its effectiveness and safety in PE warrant further investigation. The present review focused on elucidating PE pathogenesis, post-PE syndrome and the clinical application of pulmonary rehabilitation in patients with PE.

The Need for Expanding Pulmonary Rehabilitation Services

Pulmonary rehabilitation is a strongly recommended and effective treatment for people with chronic lung disease. However, access to pulmonary rehabilitation is poor. Globally, pulmonary rehabilitation is accessed by less than 3% of people with chronic lung disease. Barriers to referral, uptake and completion of pulmonary rehabilitation are well documented and linked with organizational, practitioner and patient-related factors. Enhancing the knowledge of health care professionals, family carers, and people with chronic lung disease about the program and its benefits produces modest increases in referral and uptake rates, but evidence of the sustainability of such approaches is limited. Additionally, initiatives focusing on addressing organizational barriers to access, such as expanding services and implementing alternative models to the conventional center-based setting, are not yet widely used in clinical practice. The COVID-19 pandemic has highlighted the urgent need for health care systems to deliver pulmonary rehabilitation programs remotely, safely, and efficiently. This paper will discuss the pressing need to address the issue of the low accessibility of pulmonary rehabilitation. It will also highlight the distinctive challenges to pulmonary rehabilitation delivery in rural and remote regions, as well as low-income countries.

Strategies for the prevention, diagnosis and treatment of COPD in low- and middle- income countries: the importance of primary care

INTRODUCTION

Low- and middle-income countries (LMICs) bear a high proportion of the global morbidity and mortality caused by COPD. Increased exposure to risk factors throughout life (e.g. malnutrition, indoor and outdoor air pollution, and smoking) is associated with higher COPD prevalence in LMICs and the lack of treatment availability increases avoidable harm.

AREAS COVERED

This review covers the epidemiology and burden of COPD in LMICs, and challenges and recommendations related to health-care systems, prevention, diagnosis, and treatment. Main challenges are related to under-resourced health-care systems (such as limited availability of spirometry, rehabilitation, and medicines). Lack of policy and practical local guidelines on COPD diagnosis and management further contribute to the low diagnostic and treatment rates. In the absence of, or limited number of respiratory specialists, primary care practitioners (general practitioners, nurses, pharmacists, physiotherapists, and community health workers) play an even more pivotal role in COPD management in LMICs.

EXPERT OPINION

Raising awareness on COPD, educating health-care workers, patients, and communities on cost-effective preventive measures as well as improving availability, affordability and proper use of diagnostic and pharmacological and non-pharmacologic treatment in primary care are the key interventions needed to improve COPD prevention, diagnosis, and care in LMICs.

Clinical effectiveness and components of Home-pulmonary rehabilitation for people with chronic respiratory diseases: a systematic review protocol

INTRODUCTION

Chronic respiratory diseases (CRDs) are common and disabling conditions that can result in social isolation and economic hardship for patients and their families. Pulmonary rehabilitation (PR) improves functional exercise capacity and health-related quality of life (HRQoL) but practical barriers to attending centre-based sessions or the need for infection control limits accessibility. Home-PR offers a potential solution that may improve access. We aim to systematically review the clinical effectiveness, completion rates and components of Home-PR for people with CRDs compared with Centre-PR or Usual care.

METHODS AND ANALYSIS

We will search PubMed, CINAHL, Cochrane, EMBASE, PeDRO and PsycInfo from January 1990 to date using a PICOS search strategy (Population: adults with CRDs; Intervention: Home-PR; Comparator: Centre-PR/Usual care; Outcomes: functional exercise capacity and HRQoL; Setting: any setting). The strategy is to search for 'Chronic Respiratory Disease' AND 'Pulmonary Rehabilitation' AND 'Home-PR', and identify relevant randomised controlled trials and controlled clinical trials. Six reviewers working in pairs will independently screen articles for eligibility and extract data from those fulfilling the inclusion criteria. We will use the Cochrane risk-of-bias tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to rate the quality of evidence. We will perform meta-analysis or narrative synthesis as appropriate to answer our three research questions: (1) what is the effectiveness of Home-PR compared with Centre-PR or Usual care? (2) what components are used in effective Home-PR studies? and (3) what is the completion rate of Home-PR compared with Centre-PR?

ETHICS AND DISSEMINATION

Research ethics approval is not required since the study will review only published data. The findings will be disseminated through publication in a peer-reviewed journal and presentation in conferences.

Identifying Appropriate Delivery of and Referral to Pulmonary Rehabilitation in Uganda: A Survey Study of People Living with Chronic Respiratory Disease and Health Care Workers

Introduction

Pulmonary rehabilitation (PR) is a low cost, high impact intervention that ameliorates the disability associated with chronic respiratory diseases (CRD). PR is becoming increasingly recognized in low resource settings where the burden of CRD is rapidly increasing. To aid the implementation of PR in Uganda, we conducted a study to assess the attitudes and opinions towards PR among patients with CRD in Uganda and explore barriers faced by health care workers (HCWs) in referring to PR.

Methods

A cross-sectional study comprising two survey populations: people living with CRD and HCWs regarded as potential PR referrers and PR deliverers. This exploratory study sought initial opinions and thoughts regarding PR, as well as baseline knowledge and potential barriers faced in the referral process.

Results

Overall, 30 HCWs (53% female, 43% doctors) and 51 adults with CRD (63% female) participated in the survey. Among those with CRD, the majority reported breathlessness as a major problem (86%) and breathlessness affected their ability to do paid and unpaid work (70%). Interest in PR was high amongst adults with CRD (92%) with preference for a hospital-based programme (67%) as opposed to community-based (16%) or home-based (17%). All HCWs considered PR important in lung disease management, but 77% do not refer patients due to a lack of information about PR. HCWs' free-text responses identified the need for training in PR, patient education and streamlining the referral process as key elements to develop successful PR referral services.

Conclusion

To successfully set up a PR service for people with CRD in Uganda, there is a great need for appropriately tailored training and education of prospective referrers about CRD and PR programs. Educating patients about the benefits of PR as well as streamlining the referral process is critical in expanding PR services across Uganda to fulfill this unmet need.

Exploring the barriers to pulmonary rehabilitation for patients with chronic obstructive pulmonary disease: a qualitative study

BACKGROUND

The complexity of chronic obstructive pulmonary disease (COPD) and its different physical, mental, familial, occupational, and social complications highlight the necessity of pulmonary rehabilitation (PR) for afflicted patients. However, PR for patients with COPD usually faces some barriers. The aim of this study was to explore the barriers to PR for patients with COPD.

METHODS

This qualitative descriptive study was conducted in January 2019 to October 2020. Participants were 19 patients with COPD, 11 family caregivers of patients with COPD, and 12 healthcare providers, who all were recruited purposively from two teaching hospitals in Isfahan, Iran. Data were collected through semi-structured interviews and were analyzed through conventional content analysis.

RESULTS

The barriers to PR for patients with COPD fell into three main categories, namely barriers related to patients and their families, inefficiency of PR services, and inappropriate organizational context for PR. Each category had four subcategories, namely patients' and families' lack of knowledge, complexity and chronicity of COPD, heavy financial burden of COPD, patients' frustration and discontinuation of PR, lack of patient-centeredness, lack of coordination in PR team, inadequate professional competence of PR staff, lack of a holistic approach to PR, limited access to PR services, inadequate insurance for PR services, ineffective PR planning, and discontinuity of care.

CONCLUSION

PR for patients with COPD is a complex process which faces different personal, familial, social, financial, organizational, and governmental barriers. Strategies for managing these barriers are needed in order to improve the effectiveness and the quality of PR services for patients with COPD.

Challenges in the Implementation of Chronic Obstructive Pulmonary Disease Guidelines in Low- and Middle-Income Countries: An Official American Thoracic Society Workshop Report

There is a substantial burden of chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD), in low- and middle-income countries (LMICs). LMICs have particular challenges in delivering cost-effective prevention, diagnosis, and management of COPD. Optimal care can be supported by effective implementation of guidelines. This American Thoracic Society workshop considered challenges to implementation of COPD guidelines in LMICs. We make 10 specific recommendations: 1) relevant organizations should provide LMIC-specific COPD management guidance; 2) patient and professional organizations must persuade policy-makers of the importance of lung function testing programs in LMICs; 3) healthcare education and training should emphasize the early-life origins of COPD; 4) urgent action is required by governments to reduce airborne exposures, including exposures to tobacco smoke and indoor and outdoor air pollution; 5) guidance for COPD in LMICs should explicitly link across Essential Medicine Lists and the World Health Organization package of essential noncommunicable disease interventions for primary health care in low-resource settings and should consider availability, affordability, sustainability, and cost-effective use of medicines; 6) the pharmaceutical industry should work to make effective COPD and tobacco-dependence medicines globally accessible and affordable; 7) implementation of locally adapted, cost-effective pulmonary rehabilitation programs should be an international priority; 8) the World Health Organization Global Action Plan for the Prevention and Control of Noncommunicable Diseases should specify how improvements in respiratory health will be achieved; 9) research funders should increase the proportion of funding allocated to COPD in LMICs; and 10) the respiratory community should leverage the skills and enthusiasm of earlier-career clinicians and researchers to improve global respiratory health.
