Living with breathlessness: a systematic literature review and qualitative synthesis

Quality of life associated with breathlessness in the multinational Burden of Obstructive Lung Disease (BOLD) study: A cross-sectional analysis

INTRODUCTION

Evidence of an association between breathlessness and quality of life from population-based studies is limited. We aimed to investigate the association of both physical and mental quality of life with breathlessness across several low-, middle- and high-income countries.

METHODS

We analysed data from 19 714 adults (31 sites, 25 countries) from the Burden of Obstructive Lung Disease (BOLD) study. We measured both mental and physical quality of life components using the SF-12 questionnaire, and defined breathlessness as grade ≥2 on the modified Medical Research Council scale. We used multivariable linear regression to assess the association of each quality-of-life component with breathlessness. We pooled site-specific estimates using random-effects meta-analysis.

RESULTS

Both physical and mental component scores were lower in participants with breathlessness compared to those without. This association was stronger for the physical component (coefficient = -7.59; 95%CI -8.60, -6.58; I2 = 78.5%) than for the mental component (coefficient = -3.50; 95%CI -4.36, -2.63; I2 = 71.4%). The association between physical component and breathlessness was stronger in high-income countries (coefficient = -8.82; 95%CI -10.15, -7.50). Heterogeneity across sites was partly explained by sex and tobacco smoking.

CONCLUSION

Quality of life is worse in people with breathlessness, but this association varies widely across the world.

Comparative effectiveness of pharmacological and non-pharmacological interventions for dyspnea management in advanced cancer: A systematic review and network meta-analysis

Objective

This study aimed to evaluate and rank the effectiveness of pharmacological and non-pharmacological interventions for managing dyspnea severity, anxiety, exercise capacity, and health-related quality of life (HRQoL) in patients with advanced cancer.

Methods

A comprehensive search of PUBMED, HINARI, CENTRAL, and ResearchGate was conducted to identify randomized controlled trials (RCTs) published up to March 2024. Network meta-analysis was performed to compare interventions, calculating mean differences (MD) and standardized mean differences (SMD) with 95% confidence intervals (CI). P-scores were used to rank the interventions. Risk of bias was assessed using the Cochrane tool, and the quality of evidence (QOE) was evaluated using the GRADE framework.

Results

A total of 42 RCTs, encompassing 3,832 patients, were included in the analysis. Among the evaluated interventions, high-flow nasal cannula (HFNC) demonstrated the most significant improvement in dyspnea relief (SMD = -1.91; 95% CI: -3.32 to -0.49; QOE: moderate), followed by acupressure/reflexology (SMD = -1.04; 95% CI: -2.02 to -0.06; QOE: very low). Activity rehabilitation was the only intervention that significantly reduced anxiety compared to the control group (SMD = -0.64; 95% CI: -0.97 to -0.32; QOE: very low). While all interventions showed trends of improving exercise capacity, none reached statistical significance. Notably, acupressure/reflexology significantly enhanced HRQoL (SMD = 1.55; 95% CI: 0.22 to 2.88; QOE: moderate).

Conclusions

Non-pharmacological interventions, particularly HFNC and acupressure/reflexology, were more effective than pharmacological approaches in improving dyspnea relief and HRQoL. However, the low quality of evidence underscores the need for high-quality, large-scale trials to confirm these findings and refine treatment strategies for dyspnea management in advanced cancer patients.

The invisibility of chronic breathlessness. Why don't we talk about the symptom?

PURPOSE OF REVIEW

Chronic breathlessness is distressing and debilitating, yet often under-recognised. This review summarises recent insights into the visibility of breathlessness and delineates potential contributing factors to its invisibility.

RECENT FINDINGS

Chronic breathlessness' invisibility is multi-faceted and often leads to avoidance behaviour by patients. The symptom's presence, severity and impacts can be hidden from patients, caregivers, clinicians and the public due to its insidiousness, supposed subjectivity, stigma and the ability to be modulated by reducing exertion. This leads to patients' under-reporting of their breathlessness in clinic and low levels of public unawareness. Other contributing factors can include clinicians' failure to initiate conversations about breathlessness at times because of lack of knowledge about assessment and treatment, or prioritising disease management over symptom management.

SUMMARY

There is robust evidence that chronic breathlessness is often missed, unacknowledged or misunderstood by patients, caregivers, clinicians and society. Optimised clinical recognition and response may help to reverse these trends. Longitudinal studies are needed to explore whether such perceptions can be changed. Intervention studies should address every aspect of invisibility - from clinical improvements to minimising stigma and validating the subjective experience of patients.

Exploring patients' and carers' experiences, understandings and expectations of COPD exacerbations:an interview study

BACKGROUND

Chronic obstructive pulmonary disease (COPD) exacerbations are clinically significant events that affect millions of people globally.

AIM

To explore patients' and carers' experiences, understanding, and expectations of, as well as their responses to, exacerbations.

DESIGN & SETTING

Semi-structured interviews conducted with patients who have COPD and their carers from four sites across England.

METHOD

Interviews were conducted with a purposive sample of patients with COPD and their carers recruited from four sites in England: two in Yorkshire, one in Hampshire and one in London. Interviews were theoretically informed by the Breathing Space concept and analysed using reflexive thematic analysis. This research is reported in line with the Standards for Reporting Qualitative Research.

RESULTS

Forty patient participants were recruited: 21 were female, 28 were White, with a mean age 69 years (standard deviation [SD] = 8.1 years), mean COPD duration = 11.3 years (SD = 8.3 years), median exacerbations in past year = 1.5 (range 0-9). Seven carer participants were recruited; of these, six were female and six were White. Three themes were identified: the language that clinicians use in COPD is important; episodes of symptom worsening have profound impacts on patients and carers; and patients' early experiences, including the responses of clinicians to their help-seeking, have a lasting effect on their behaviour. How patients respond to symptom worsening can be considered holistically in the context of the Breathing Space framework. Breathlessness affected all patient participants and was a key symptom that precipitated action.

CONCLUSIONS

Our findings show how early help-seeking experiences shape later behaviour. Early emphasis on symptom management, preparation for exacerbations, and post-exacerbation reviews are practical ways that clinicians can support patients and carers to manage these events better. The Breathing Space concept provides a useful framework to identify needs and tailor COPD management appropriately.

Diagnostic pathways for earlier diagnosis and treatment towards better outcomes for adults living with chronic breathlessness

Chronic breathlessness is a common and distressing symptom, negatively impacting physical function and quality of life. Many individuals presenting with chronic breathlessness wait years for an explanatory diagnosis, leading to delays in accessing effective treatments and worse individual outcomes including premature mortality. In addition, delays to diagnosis are associated with increased healthcare utilisation and therefore potentially avoidable burden on healthcare systems. Diagnosing the underlying causes of chronic breathlessness is complex and can be challenging for clinicians. The current clinical diagnostic approach, related guidelines, and healthcare service structure are typically aligned with a disease-based focus. For this article, we are using a working definition of 'Chronic Breathlessness' to infer breathlessness that has persisted for at least eight weeks. In this narrative review, using the latest available evidence, we aimed to describe a symptom-based approach to diagnosis for adults presenting with chronic breathlessness alongside describing the potential for this approach to improve both clinical outcomes and efficiency for healthcare systems. Therefore, our objectives were to: 1) summarise what is currently known about the time to diagnosis for adults presenting with breathlessness, 2) describe the impact and possible explanations for the current delays to diagnosis, 3) describe potential solutions towards an effective symptom-based diagnosis, 4) review the potential for Artificial Intelligence (AI) to support several areas along the diagnostic pathway for breathlessness, 5) describe how a symptom-based approach to diagnosis can be directly utilised to enable a 'matched' personalised holistic approach to treatment.

BREATHLEssness in INDIA (BREATHE-INDIA): realist review to develop explanatory programme theory about breathlessness self-management in India

Breathlessness is highly prevalent in low and middle-income countries (LMICs). Low-cost, non-drug, breathlessness self-management interventions are effective in high-income countries. However, health beliefs influence acceptability and have not been explored in LMIC settings. Review with stakeholder engagement to co-develop explanatory programme theories for whom, if, and how breathlessness self-management might work in community settings in India. Iterative and systematic searches identified peer-reviewed articles, policy and media, and expert-identified sources. Data were extracted in terms of contribution to theory (high, medium, low), and theories developed with stakeholder groups (doctors, nurses and allied professionals, people with lived experiences, lay health workers) and an International Steering Group (RAMESES guidelines (PROSPERO42022375768)). One hundred and four data sources and 11 stakeholder workshops produced 8 initial programme theories and 3 consolidated programme theories. (1) Context: breathlessness is common due to illness, environment, and lifestyle. Cultural beliefs shape misunderstandings about breathlessness; hereditary, part of aging, linked to asthma. It is stigmatised and poorly understood as a treatable issue. People often use rest, incense, or tea, while avoiding physical activity due to fear of worsening breathlessness. Trusted voices, such as healthcare workers and community members, can help address misconceptions with clear, simple messages. (2) Breathlessness intervention applicability: nonpharmacological interventions can work across different contexts when they address unhelpful beliefs and behaviours. Introducing concepts like "too much rest leads to deconditioning" aligns with cultural norms while promoting beneficial behavioural changes, such as gradual physical activity. Acknowledging breathlessness as a medical issue is key to improving patient and family well-being. (3) Implementation: community-based healthcare workers are trusted but need simple, low-cost resources/skills integrated into existing training. Education should focus on managing acute episodes and daily breathlessness, reducing fear, and encouraging behavioural change. Evidence-based tools are vital to gain support from policymakers and expand implementation. Breathlessness management in India must integrate symptom management alongside public health and disease treatment strategies. Self-management interventions can be implemented in an LMIC setting. However, our novel methods indicate that understanding the context for implementation is essential so that unhelpful health beliefs can be addressed at the point of intervention delivery.

BreathCarer: Informal carers of patients with chronic breathlessness: a mixed-methods systematic review of burden, needs, coping, and support interventions

BACKGROUND

Breathlessness is a common symptom in chronic and advanced diseases, and it poses a significant burden to patients and to their informal carers. They play a crucial role in sustainable care for patients living with breathlessness, but their challenges and needs are often neglected.

OBJECTIVE

To provide a systematic overview of the literature on the burden, needs, coping and use of healthcare and social services by carers of patients suffering from chronic breathlessness due to any life-limiting disease.

DESIGN

A mixed-methods systematic review (PROSPERO CRD42022312989).

DATA SOURCES

Medline, CENTRAL, PsycINFO, and CINAHL were searched and complemented with forward and backward searches and expert consultation.

REVIEW METHODS

The mixed-methods review included any study on burden, needs and coping among carers of patients with breathlessness published from the inception of the databases until July 2023. A narrative analysis of the quantitative results and a pragmatic meta-aggregation of the qualitative findings were performed, followed by a mixed-methods convergent segregated approach.

FINDINGS

A total of 53 studies with 4,849 carers were included. Breathlessness is highly burdensome for carers who live with and care for patients or for those who do not live with the patients and care for them. Breathlessness is a significant risk factor for high carers' burden, contributing to deteriorating physical and mental health among carers and creating an urgent need for external support. A major challenge is the sense of being trapped in a state of constant alertness and anxiety, centred around managing the patient's breathlessness. Carers bear substantial emotional burden due to uncertainty, sleep disturbances, and social isolation, which leads to severe psychological distress. Their unmet needs for professional guidance, self-management strategies, and social interaction are high. While supportive interventions, such as specialized services and multidisciplinary approaches, can alleviate some of the burden, there remains a lack of targeted interventions specifically designed for carers.

CONCLUSIONS

This review highlights the substantial burden associated with caring for patients with chronic breathlessness, the unmet needs of carers and the lack of supportive care structures, leaving them with little option but to accept the situation.

"I'm living in a 'no' world now…"- A qualitative study of the widespread impact of living with chronic breathlessness, and experiences of identification and assessment of this symptom in an older, frail community-based population

Chronic breathlessness is a debilitating symptom with detrimental impact on individuals and carers. However, little is known about the experiences of community-dwelling, frail, older adults living with chronic breathlessness. To explore, (i) the psychological impact of living with chronic breathlessness, (older frail adult patients, carers) and (ii) how patients, carers, and clinicians experience identification and assessment of chronic breathlessness in the primary care setting. In-depth semi-structured interviews with eligible older adults (≥65 years; moderate to severe frailty [electronic Frailty Index >0.36]), and carers recruited from a community-based Integrated Care Centre in England. Clinicians were recruited from the Centre and affiliated GP practices. Recorded in-person interviews were transcribed and subjected to reflexive thematic analysis using Total Dyspnoea and Breathing Space conceptual frameworks. 20 patients (9 females), carers (4 spouses, 1 daughter), and clinicians (5 GPs, 3 advanced clinical practitioners, 2 nurses) were interviewed. Four themes were identified: (1) Widespread negative impact of chronic breathlessness. Breathlessness adversely impacts physical and psychological wellbeing. (2) Barriers to optimal health-seeking and identification of chronic breathlessness. Breathlessness is 'one of many' symptoms, and not prioritised in 'one appointment, one problem' consultations. Clinicians do not routinely ask about breathlessness. Patients are unaware of breathlessness-specific therapies. (3) Variations in chronic breathlessness management. Management is limited; few are offered evidence-based treatments (e.g., handheld fan) and patients find their own strategies. (4) Need for education and information. Clinicians felt helpless about breathlessness management, and patients lacked understanding and had low expectations of receiving help for this symptom. Breathlessness adversely impacts the psychological wellbeing of older frail adults. Chronic breathlessness in older, frail adults is invisible, unidentified and unmanaged in primary care. Evidence-based breathlessness interventions are available, but not routinely implemented with few patients accessing them. Proactive identification, assessment and management of breathlessness in primary care is needed to support adults living with chronic breathlessness.

Advances in breathlessness support services for people with serious illness

PURPOSE OF REVIEW

Breathlessness remains a common and distressing symptom among people with serious illness, particularly in advanced disease. This review synthesises recent advances in the development, characteristics, and outcomes of breathlessness support services.

RECENT FINDINGS

The expanding body of evidence regarding breathlessness support services has broadened and strengthened our understanding of clinical and cost-effectiveness. The expansion of these services, into diverse settings and including digital delivery, has augmented their reach and accessibility to a wider population. Additionally, there is increasing attention to the psychological aspects of breathlessness and its management, including the challenges of optimising breathlessness support services for long-term benefit.

SUMMARY

Recent studies have made substantial progress in enhancing our knowledge of breathlessness support services and their impact on people with serious illness. Innovations extending services into new countries and settings, including use of digital platforms for intervention delivery, plus increased recognition of psychological mechanisms, have the potential to support more people with serious illness to live as best as possible with breathlessness.

End-stage heart failure patients in ICU: the importance of advance planning and effective communication

During the disease trajectory, patients with advanced heart failure are often hospitalised with a high probability of admission to the intensive care setting. Using a case study, this article explores the care given to a patient with decompensated heart failure in an intensive care unit (ICU). It will discuss the significance of holistic assessment and effective symptom management, in particular the research related to breathlessness management. The importance of effective communication within the ICU multidisciplinary team, including with the patient/family will be explored, as the ICU environment can often lead to communication breakdown, patients being unable to voice their wishes and over-medicalisation. The effectiveness of early involvement of the palliative care team in ICU will be examined, including the use of tools such advance care planning and a treatment escalation plan and whether use of these can enable a better patient and family experience at the end of life. The role of palliative care champions will be discussed.

Using a Patient-Reported Outcome Measure to Assess Physical, Psychosocial, and Existential Issues in COPD

Background: Chronic obstructive pulmonary disease (COPD) is marked by severe physical symptoms, impaired quality of life, and high psychological distress. Despite its impact, the identification of not only physical but also psychosocial and existential issues in the clinic lags behind that of other patient groups. Methods: This study aimed to assess physical, psychosocial, and existential issues among patients with COPD using a patient-reported outcome measure for general palliative care (the 'PRO-Pall') in a Danish outpatient clinic. We included 115 adults with COPD who completed the PRO-Pall either electronically or in the clinic. Sociodemographic and illness-related data were retrieved from their electronic health records. Results: We found that shortness of breath, tiredness, and difficulty walking were predominant physical issues. Worry about change in social roles was the most frequently reported psychosocial issue, while existential issues were reported by approximately one in ten patients. Most patients (44.5%) felt able to share their feelings with family or friends, and a majority (62.2%) felt their illness-related issues were addressed satisfactorily. Females expressed a greater need for rest and males more frequently reported intimacy issues. Higher COPD-impact on life measured by the COPD Assessment Test was associated with lower ratings on the quality-of-life item of the PRO-Pall independent of age, gender, lung function, and smoking status. Conclusions: Patients reported issues in physical, psychosocial, and existential dimensions of the PRO-Pall. The PRO-Pall shows potential as a broader alternative to measures that focus mainly on physical issues.

Unveiling the burden of COPD: perspectives on a patient-reported outcome measure to support communication in outpatient consultations-an interview study among patients

Introduction

Chronic Obstructive Pulmonary Disease (COPD) profoundly affects physical, psychological, and social aspects of life, yet these issues often remain unaddressed. Patient-Reported Outcomes Measures (PROM) have the potential to address these issues by promoting person-centered communication. However, their impact in COPD practice remains uncertain. This study aimed to investigate how patients with COPD perceive the usefulness of a new holistic PROM for general palliative care (PRO-Pall) before and during outpatient consultations.

Methods

Semi-structured telephone interviews were conducted with patients diagnosed with moderate to very severe COPD, 2-5 days after consultation at a respiratory outpatient clinic in Denmark. Interviews were transcribed verbatim and analyzed inductively using qualitative content analysis.

Results

Nine patients (five males; mean age: 66 years) participated in the study with four themes emerging: (1) Unlocking thoughts: Completing PRO-Pall stimulated patients' self-reflection, which revealed previously overlooked COPD-related issues, particularly psychosocial challenges. (2) Unmasking concerns: Patients felt encouraged to be honest, rather than concealing their concerns. (3) Breaking the ice: PRO-Pall responses enabled direct questioning by healthcare professionals during consultations, initiating discussions on patients' sensitive yet vital COPD-related matters. (4) Deepening the dialogue: Healthcare professionals' targeted and attentive approach fostered more holistic and meaningful discussions, providing most patients with a deeper understanding of psychosocial issues affecting their well-being.

Conclusion

Completing PRO-Pall prior to outpatient consultations prompted most patients with COPD to unveil previously unacknowledged psychosocial challenges. During consultations, addressing these challenges initiated open discussions on individual concerns, enhancing most patients' understanding of the multifaceted burden of COPD.

Changes in COPD-related anxiety symptoms during pulmonary rehabilitation: a prospective quantitative and qualitative study

Background

Fear-avoidance in COPD can have detrimental effects on pulmonary rehabilitation (PR) outcomes and is therefore important to address. This prospective study examined changes in and management of COPD-related anxiety symptoms over the course of a PR program.

Methods

Patients with COPD referred to 9-weeks of PR in the municipality of Vejle, Denmark from January to December 2022 completed a six-minute walk test (6MWT) and the following questionnaires, both before and after PR: COPD Anxiety Questionnaire 20-item version (CAF-R), measuring COPD-related anxiety; COPD Assessment Test (CAT), measuring COPD-related disability; 12-Item Short-Form Health Survey (SF-12), measuring health-related quality of life (HR-QoL); sociodemographic and disease-related information. After PR, a subsample of the patients took part in semi-structured interviews exploring their understanding of how they managed COPD-related anxiety during PR. Pre- and post-assessment of COPD-related anxiety and other PR outcomes were analysed with t-tests and correlation analyses. Qualitative interviews were analysed using a thematic analysis approach.

Results

A total of 72 patients with COPD (mean ± SD age 71 ± 8, 53% female) were included in the study, and 13 took part in qualitative interviews. A significant decrease in COPD-related anxiety was observed from before to after PR, corresponding to a small effect size (Cohen's d = 0.32; p = 0.018). Reductions in COPD-related anxiety were not associated with improvements in COPD-related disability, HR-QOL, or functional exercise capacity. The qualitative findings identified four anxiety management strategies, i.e., "planning", "problem-solving", "accepting", and "confronting", which were influenced by interactions with healthcare professionals and co-patients as well as patients' own perception.

Conclusions

COPD-related anxiety symptoms was reduced after PR, potentially through the use of various management strategies. The strategies appeared to be influenced by interactional factors during the PR program.

Tai Chi and Aerobic Exercise on Cancer-Related Dyspnea in Advanced Lung Cancer Patients: A Randomized Clinical Trial

CONTEXT

Dyspnea, a prevalent and debilitating symptom in patients with advanced lung cancer, negatively affects symptom burden and prognosis. Physical activity has emerged as a promising non-pharmacological intervention for managing dyspnea.

OBJECTIVES

This study compared the effectiveness of two widely-recognized physical activity modalities, namely Tai Chi (TC) and aerobic exercise (AE) for treating dyspnea in patients with advanced lung cancer.

METHODS

Patients with advanced lung cancer (n=226) were randomized into TC, AE, or control groups. There was no baseline dyspnea requirement for patients. The AE group received two 60-minute supervised sessions and home-based exercises per month, the TC group received 60-minute sessions twice weekly, and the control group received exercise guidelines for 16 weeks. The primary outcome (sleep quality) of the study has been previously reported. In this secondary analysis, we focused on dyspnea outcomes, including overall and lung cancer-specific dyspnea. Assessments were conducted at baseline (T0), 16 weeks (T1), and one year (T2).

RESULTS

Compared to the control group, TC significantly improved overall dyspnea at T1 (between-group difference, -8.69; P=0.03) and T2 (between-group difference, -11.45; P=0.01), but not AE. Both AE (between-group difference, -11.04; P=0.01) and TC (between-group difference, -14.19; P<0.001) significantly alleviated lung cancer-specific dyspnea at T2 compared with the control group.

CONCLUSION

Both TC and AE alleviate dyspnea severity in patients with advanced lung cancer, and continuous exercise can yield substantial improvements. Due to its multi-component nature, Tai Chi has a greater effect on dyspnea.

Disability and long-term breathlessness: a cross-sectional, population study

INTRODUCTION

Disability, resulting from altered interactions between individuals and their environment, is a worldwide issue causing inequities and suffering. Many diseases associated with breathlessness cause disability but the relationship between disability and the severity of breathlessness itself is unknown.This study evaluated associations between disability using the WHO's Disability Assessment Schedule (WHODAS) 2.0 and levels of long-term breathlessness limiting exertion.

METHODS

This population-based, cross-sectional online survey (n=10 033) reflected the most recent national census (2016) by age, sex, state/territory of residence and rurality. Assessments included self-reported disability (WHODAS 2.0 12-item (range 12 (no disability) to 60 (most severe disability)) assessed in 6 domains) and long-term breathlessness limiting exertion (modified Medical Research Council (mMRC) breathlessness scale; 0-4 (4-most severe)). Days in the last month affected by breathlessness were reported.

RESULTS

Of respondents (52% women; mean age 45), mean total disability score was 20.9 (SD 9.5). 42% (n=4245) had mMRC >0 (mMRC1 31% (n=3139); mMRC2 8% (n=806); mMRC3,4 3% (n=300)). Every level of long-term breathlessness limiting exertion was associated with greater levels of disability (total p <0.001; each domain p <0.001). The most compromised domains were Mobility and Participation.In the last 30 days, people with severe breathlessness (mMRC 3-4): experienced disability (20 days); reduced activities/work (10 days); and completely forwent activities (another 5 days).

CONCLUSIONS

Disability should be in the definition of persistent breathlessness as it is systematically associated with long-term breathlessness limiting exertion in a grade-dependent, multidimensional manner. Disability should be assessed in people with long-term breathlessness to optimise their social well-being and health.

Nursing interventions to promote dyspnea self-management of complex chronic patients: An integrated review

OBJECTIVES

Chronic dyspnea, a distressing symptom in patients with complex chronic conditions, is linked to higher risks of mortality. This study aimed to identify nursing interventions that could improve self-management for complex chronic patients, thereby enhancing control over chronic dyspnea. The findings intend to guide nursing care strategies that promote self-management among this population.

METHODS

We searched the databases Medline, Scopus, Web of Science, CINAHL, Cochrane Database of Systematic Reviews (CDSR), and Joanna Briggs Institute (JBI) databases were searched in December 2023. We included adult patients with complex chronic conditions with chronic dyspnoea. The team screened articles collaboratively, using Rayyan software. A qualitative appraisal was performed according to JBI Critical Appraisal Checklist tools. The review protocol is registered under the number CRD42023456021.

RESULTS

Our review included 18 studies that explored a variety of interventions for chronic dyspnea. We identified pharmacological interventions (such as oxygen therapy and inhalation treatments) and non-pharmacological approaches (including educational programs, breathing exercises, fluid intake management, body awareness techniques, peer support, emotional intelligence training, and the use of web applications). Those interventions empower patients, improve their ability to fulfill life roles, mitigate emotional distress, and improve overall quality of life. Nursing care can be crucial in enabling individuals to achieve independence and autonomy in self-care.

CONCLUSIONS

Promoting self-management for chronic dyspnea in complex chronic patients requires a holistic approach, encompassing multidisciplinary interventions, individualized self-care education, peer engagement, and technological support. Current research on self-management inadequately addresses interventions targeting patient behaviour change. It highlights the need to delve deeper into the self-management process. Further research is needed to expand the evidence base and refine these interventions.

Blunted perception of breathlessness in three cases of low grade insular-glioma

Better understanding of breathlessness perception addresses an unmet clinical need for more effective treatments for intractable dyspnoea, a prevalent symptom of multiple medical conditions. The insular-cortex is predominantly activated in brain-imaging studies of dyspnoea, but its precise role remains unclear. We measured experimentally-induced hypercapnic air-hunger in three insular-glioma patients before and after surgical resection. Tests involved one-minute increments in inspired CO2, raising end-tidal PCO2 to 7.5 mmHg above baseline (38.5 ± 5.7 mmHg), whilst ventilation was constrained (10.7 ± 2.3 L/min). Patients rated air-hunger on a visual analogue scale (VAS). Patients had lower stimulus-response (2.8 ± 2 vs. 11 ± 4 %VAS/mmHg; p = 0.004), but similar threshold (40.5 ± 3.9 vs. 43.2 ± 5.1 mmHg), compared to healthy individuals. Volunteered comments implicated diminished affective valence. After surgical resection; sensitivity increased in one patient, decreased in another, and other was unable to tolerate the ventilatory limit before any increase in inspired CO2.We suggest that functional insular-cortex is essential to register breathlessness unpleasantness and could be targeted with neuromodulation in chronically-breathless patients. Neurological patients with insula involvement should be monitored for blunted breathlessness to inform clinical management.

The effect of unpredictability on the perception of breathlessness: a narrative review

Breathlessness is an aversive bodily sensation impacting millions of people worldwide. It is often highly detrimental for patients and can lead to profound distress and suffering. Notably, unpredictable breathlessness episodes are often reported as being more severe and unpleasant than predictable episodes, but the underlying reasons have not yet been firmly established in experimental studies. This review aimed to summarize the available empirical evidence about the perception of unpredictable breathlessness in the adult population. Specifically, we examined: (1) effects of unpredictable relative to predictable episodes of breathlessness on their perceived intensity and unpleasantness, (2) potentially associated neural and psychophysiological correlates, (3) potentially related factors such as state and trait negative affectivity. Nine studies were identified and integrated in this review, all of them conducted in healthy adult participants. The main finding across studies suggested that unpredictable compared to predictable, breathlessness elicits more frequently states of high fear and distress, which may contribute to amplify the perception of unpredictable breathlessness, especially its unpleasantness. Trait negative affectivity did not seem to directly affect the perception of unpredictable breathlessness. However, it seemed to reinforce state fear and anxiety, hence possible indirect modulatory pathways through these affective states. Studies investigating neural correlates of breathlessness perception and psychophysiological measures did not show clear associations with unpredictability. We discuss the implication of these results for future research and clinical applications, which necessitate further investigations, especially in clinical samples suffering from breathlessness.

Social suffering in individuals with chronic obstructive pulmonary disease: a secondary analysis of interpretative phenomenological study

Individuals with chronic obstructive pulmonary disease experience suffering that affects their families and community relationships. However, no studies provide an explicit account of social suffering among these individuals. This secondary analysis was conducted to understand the lived experiences of social suffering in individuals with chronic obstructive pulmonary disease. The theory of social suffering guided the analysis of an interpretative phenomenological study. Thirteen individuals were recruited using purposive sampling. Data were analyzed using reflexive thematic analysis. Three themes were generated: a) prevailing hopelessness and burden, b) progressing relational adversities, and c) struggling with co-dependency. Social suffering is a complex entity experienced by the patients and the family caregivers. For enhanced caregiving, health professionals could prepare patients to tackle the suffering through collective actions.

The impact of regular, low-dose, sustained-release morphine for chronic breathlessness on caregiver burden: An exploratory analysis of the BEAMS trial

BACKGROUND

Chronic breathlessness adversely impacts people with chronic obstructive pulmonary disease and their caregivers (family and friends), who may, in turn, experience significant burden due to their caregiving role. Sustained-release morphine may reduce chronic breathlessness in some patients, which may have an impact on caregivers' perceived burden.

AIM

To explore the impact on caregiver burden of active treatment of people with chronic breathlessness (modified Medical Research Council (mMRC) ⩾ 3) and chronic obstructive pulmonary disease (COPD) with regular, low-dose, sustained-release morphine within a multi-site, double-blind, randomised, placebo-controlled trial.

DESIGN

Exploratory analysis of self-reported caregiver burden at baseline and end of week 3 in a randomised, double-blind, placebo-controlled study. Caregiver measures included: demographics and perceived burden (Zarit Burden Interview 12-item short-form questionnaire). Patient measures included: worst breathlessness and FitBitR-measures.

SETTING/PARTICIPANTS

All consenting caregivers of trial patient participants in a multi-site study recruiting from palliative care and respiratory services.

RESULTS

Caregivers (n = 49; 59% women; median age 68 years [IQR 50-75]) reported median baseline caregiver burden 12 [IQR 5-17], with 53% reporting high burden (⩾13). Eighty-four percent of caregivers reported no change in burden. In people whose worst breathlessness improved, caregiver burden moved in the same direction, though the correlation was not significant (rs = 0.25, p = 0.17). Conversely, caregiver burden worsened as patients' minutes lightly active increased, with the correlation being significant (rs = 0.56, p = 0.04).

CONCLUSIONS

Caregivers reported high levels of caregiver burden, but patients' response to treatment in terms of their symptom and function may influence change in caregiver burden over a three-week period.

Non-medical devices for chronic breathlessness: use, barriers and facilitators for patients, carers and clinicians - a scoping review

BACKGROUND

Non-medical devices such as the handheld fan (fan), mobility aids (wheeled walkers with seats) and inspiratory muscle training (IMT) devices offer benefits for patient management of chronic breathlessness. We examined the published evidence regarding patient, carer and clinician use of the fan, mobility aids and IMT devices for chronic breathlessness management, and the potential barriers and facilitators to day-to-day use in a range of settings.

METHODS

MEDLINE, Embase, Scopus, EBSCO and the Cochrane Database of Systematic Reviews were searched. Papers were imported into EndNote and Rayyan for review against a priori eligibility criteria. Outcome data relevant to use were extracted and categorised as potential barriers and facilitators, and a narrative synthesis exploring reasons for similarities and differences conducted.

RESULTS

Seven studies met the inclusion criteria (n=5 fan, n=2 mobility aids and n=0 IMT devices). All of the studies presented patient use of non-medical devices only. Patients found the fan easy to use at home. Mobility aids were used mainly for outdoor activities. Outdoor use for both devices were associated with embarrassment. Key barriers included: appearance; credibility; self-stigma; technical specifications. Common facilitators were ease of use, clinical benefit and feeling safe with the device.

CONCLUSION

The efforts of patients, carers and clinicians to adopt and use non-medical devices for the management of chronic breathlessness is impeded by lack of implementation research. Future research should improve knowledge of the barriers and facilitators to use. This would enhance understanding of how decision-making in patient-carer-clinician triads impacts on non-medical devices use for breathlessness management.

Chronic breathlessness in advanced cardiorespiratory disease: patient perceptions of opioid use

OBJECTIVE

Low-dose oral opioids may improve severe chronic breathlessness in advanced cardiorespiratory diseases. Prescription of opioids for breathlessness occurs infrequently however, with little known about patients' attitudes towards their use in this setting. The aim of this qualitative study was to explore patients' perceptions regarding opioids for the management of severe chronic breathlessness in people with advanced cardiorespiratory disease.

METHODS

A cross-sectional, qualitative study was undertaken using outpatients with severe chronic breathlessness due to either severe chronic obstructive pulmonary disease (COPD) or chronic heart failure (CHF). Indepth, semistructured interviews were audio-recorded, transcribed verbatim and coded. Thematic analysis was undertaken to extrapolate recurring ideas from the data.

RESULTS

Twenty-four participants were purposively sampled from three different groups: opioid-naïve patients with COPD (n=7), opioid-naïve patients with CHF (n=7) and patients with COPD using opioids currently or previously for severe chronic breathlessness (n=10). Four major themes were shared by both the opioid-naïve and opioid-experienced cohorts: (1) stigmatised attitudes and beliefs regarding opioids, (2) limited knowledge and information-seeking behaviour regarding opioids, (3) the impact of the relationships with health professionals and continuity of care, and (4) the significance of past experiences with opioids. An additional theme that was unique to the opioid-experienced cohort was (5) the perception of benefit and improved quality of life.

CONCLUSION

Lack of knowledge regarding the role of opioids in managing severe chronic breathlessness, opioid misinformation and social stigmas are major barriers to opioid therapy that may be overcome by accurate information from trusted health professionals.

Repeated exposure to aversive sensations differentially affects neural gating and bodily perception

Habituation to bodily sensations is highly relevant for the experience of chronic bodily symptoms, but the neural mechanisms behind diminished habituation are currently unclear. One potentially relevant mechanism is neural gating (NG), reflected as the short-term suppression of cortical responses to redundant stimuli. We investigated the effects of repeated exposure to aversive sensations on NG and subjective perception in 91 healthy adults, by measuring their NG of respiratory and electrocutaneous stimuli using electroencephalography during two sessions separated by one week, in addition to their self-report of intensity and unpleasantness of the sensations. To test for intra- and cross-modal effects, 1/2 participants returned three times in the intervening week to experience additional aversive respiratory stimulation, while the other 1/2 received aversive electrocutaneous stimulation. Participants reported lower unpleasantness of all sensations in the final session (intra- and cross-modal habituation). NG was improved for respiratory sensations only in the group receiving additional respiratory stimulation (intra-modal habituation). We found no relationships between NG and perceptual habituation, adding to the mixed results on the relevance of NG to perceptual changes in healthy adults. Future research with clinical populations and different methods is encouraged to further clarify the mechanisms behind neural gating and diminished symptom habituation.

Nursing support for breathlessness in patients with cancer: a scoping review

OBJECTIVE

To identify nursing support provided for the relief of breathlessness in patients with cancer.

DESIGN

A scoping review following a standard framework proposed by Arksey and O'Malley.

STUDY SELECTION

Electronic databases (PubMed, CINAHL, CENTRAL and Ichushi-Web of the Japan Medical Abstract Society Databases) were searched from inception to 31 January 2022. Studies reporting on patients with cancer (aged ≥18 years), intervention for relief from breathlessness, nursing support and quantitatively assessed breathlessness using a scale were included.

RESULTS

Overall, 2629 articles were screened, and 27 were finally included. Results of the qualitative thematic analysis were categorised into 12 nursing support components: fan therapy, nurse-led intervention, multidisciplinary intervention, psychoeducational programme, breathing technique, walking therapy, inspiratory muscle training, respiratory rehabilitation, yoga, acupuncture, guided imagery and abdominal massage.

CONCLUSIONS

We identified 12 components of nursing support for breathlessness in patients with cancer. The study results may be useful to understand the actual state of nursing support provided for breathlessness in patients with terminal cancer and to consider possible support that can be implemented.

A Mixed Methods Evaluation of a Pilot Multidisciplinary Breathlessness Support Service

Breathlessness support services have demonstrated benefits for breathlessness mastery, quality of life and psychosocial outcomes for people living with breathlessness. However, these services have predominantly been implemented in hospital and home care contexts. This study aims to evaluate the adaptation and implementation of a hospice-based outpatient Multidisciplinary Breathlessness Support Service (MBSS) in Ireland. A sequential explanatory mixed methods design guided this study. People with chronic breathlessness participated in longitudinal questionnaires (n = 10), medical record audit (n = 14) and a post-discharge interview (n = 8). Caregivers (n = 1) and healthcare professionals involved in referral to (n = 2) and delivery of (n = 3) the MBSS participated in a cross-sectional interview. Quantitative and qualitative data were integrated deductively via the pillar integration process, guided by the RE-AIM framework. Integration of mixed methods data enhanced understanding of factors influencing the reach, adoption, implementation and maintenance of the MBSS, and the potential outcomes that were most meaningful for service users. Potential threats to the sustainability of the MBSS related to potential preconceptions of hospice care, the lack of standardized discharge pathways from the service and access to primary care services to sustain pharmacological interventions. This study suggests that an adapted multidisciplinary breathlessness support intervention is feasible and acceptable in a hospice context. However, to ensure optimal reach and maintenance of the intervention, activities are required to ensure that misconceptions about the setting do not influence willingness to accept referral to MBSS services and integration of services is needed to enable consistency in referral and discharge processes.

Modified-release morphine or placebo for chronic breathlessness: the MABEL trial protocol

Chronic breathlessness, a persistent and disabling symptom despite optimal treatment of underlying causes, is a frightening symptom with serious and widespread impact on patients and their carers. Clinical guidelines support the use of morphine for the relief of chronic breathlessness in common long-term conditions, but questions remain around clinical effectiveness, safety and longer term (>7 days) administration. This trial will evaluate the effectiveness of low-dose oral modified-release morphine in chronic breathlessness. This is a multicentre, parallel group, double-blind, randomised, placebo-controlled trial. Participants (n=158) will be opioid-naïve with chronic breathlessness due to heart or lung disease, cancer or post-coronavirus disease 2019. Participants will be randomised 1:1 to 5 mg oral modified-release morphine/placebo twice daily and docusate/placebo 100 mg twice daily for 56 days. Non-responders at Day 7 will dose escalate to 10 mg morphine/placebo twice daily at Day 15. The primary end-point (Day 28) measure will be worst breathlessness severity (previous 24 h). Secondary outcome measures include worst cough, distress, pain, functional status, physical activity, quality of life, and early identification and management of morphine-related side-effects. At Day 56, participants may opt to take open-label, oral modified-release morphine as part of usual care and complete quarterly breathlessness and toxicity questionnaires. The study is powered to be able to reject the null hypothesis and an embedded normalisation process theory-informed qualitative substudy will explore the adoption of morphine as a first-line pharmacological treatment for chronic breathlessness in clinical practice if effective.

Exploring the Experience of Breathlessness with the Common-Sense Model of Self-Regulation (CSM)

Chronic breathlessness is a multidimensional, unpleasant symptom common to many health conditions. The Common-Sense Model of Self-Regulation (CSM) was developed to help understand how individuals make sense of their illness. This model has been underused in the study of breathlessness, especially in considering how information sources are integrated within an individual's cognitive and emotional representations of breathlessness. This descriptive qualitative study explored breathlessness beliefs, expectations, and language preferences of people experiencing chronic breathlessness using the CSM. Twenty-one community-dwelling individuals living with varying levels of breathlessness-related impairment were purposively recruited. Semi-structured interviews were conducted with questions reflecting components of the CSM. Interview transcripts were synthesized using deductive and inductive content analysis. Nineteen analytical categories emerged describing a range of cognitive and emotional breathlessness representations. Representations were developed through participants' personal experience and information from external sources including health professionals and the internet. Specific words and phrases about breathlessness with helpful or nonhelpful connotations were identified as contributors to breathlessness representations. The CSM aligns with current multidimensional models of breathlessness and provides health professionals with a robust theoretical framework for exploring breathlessness beliefs and expectations.

Nonpharmacological management of psychological distress in people with COPD

Psychological distress is prevalent in people with COPD and relates to a worse course of disease. It often remains unrecognised and untreated, intensifying the burden on patients, carers and healthcare systems. Nonpharmacological management strategies have been suggested as important elements to manage psychological distress in COPD. Therefore, this review presents instruments for detecting psychological distress in COPD and provides an overview of available nonpharmacological management strategies together with available scientific evidence for their presumed benefits in COPD. Several instruments are available for detecting psychological distress in COPD, including simple questions, questionnaires and clinical diagnostic interviews, but their implementation in clinical practice is limited and heterogeneous. Moreover, various nonpharmacological management options are available for COPD, ranging from specific cognitive behavioural therapy (CBT) to multi-component pulmonary rehabilitation (PR) programmes. These interventions vary substantially in their specific content, intensity and duration across studies. Similarly, available evidence regarding their efficacy varies significantly, with the strongest evidence currently for CBT or PR. Further randomised controlled trials are needed with larger, culturally diverse samples and long-term follow-ups. Moreover, effective nonpharmacological interventions should be implemented more in the clinical routine. Respective barriers for patients, caregivers, clinicians, healthcare systems and research need to be overcome.

Preferences for support in managing symptoms of an asthma flare-up: a pilot study of a discrete choice experiment

Objective: Information on the preferences of people with asthma for support in managing a flare-up can inform service design which may facilitate appropriate help-seeking. To date, little is known about support preferences for managing a flare-up. The aim of this study was to develop and pilot a discrete choice experiment (DCE) to elicit the preferences of people with asthma with regards to support in managing a flare-up.Methods: Steps in developing the DCE included identification and selection of attributes and levels of the support services, construction of choice tasks, experimental design, construction of DCE instrument, and pretest (n=16) and pilot (n=38) studies of the DCE instrument. A multinomial logit model was used to examine the strength and direction of the six attributes in the pilot study.Results: Our results indicate that from a patient perspective, having a healthcare professional that listens to their concerns was the most valued attribute of support in asthma flare-up management. The other features of support valued by participants were timely access to consultation, a healthcare professional with knowledge of their patient history, a specialist doctor and face-to-face communication. Having a written action plan was the least valued attribute.Conclusions: Our findings suggest patient preference for a model of support in managing their symptoms which includes timely, face-to-face access to a healthcare professional that knows them and listens to their concerns. The findings of the pilot study need to be verified with a larger sample and using models to account for preference heterogeneity.

Tests to uncover and assess breathlessness: a proposed framework

PURPOSE OF REVIEW

Breathlessness is a common, distressing, and limiting symptom that many people avoid by reducing their activity. This review discusses exertional tests that can be used for uncovering and assessing breathlessness depending on the person's severity of illness, function, the setting, and aim of the assessment.

RECENT FINDINGS

Standardized exertional tests are useful to uncover 'hidden' breathlessness earlier in people who may have adapted their physical activity to limit their breathing discomfort. In 'more fit' ambulatory people and outpatients, cardiopulmonary exercise testing is the gold standard for assessing symptom severity, underlying conditions, and mechanisms and treatment effects. Among field tests, the 6-min walk test is not useful for assessing breathlessness. Instead, the 3-min step test and walk test are validated for measuring breathlessness change in chronic obstructive pulmonary disease. In people with more severe illness (who are most often not breathless at rest), reported tests include upper limb exercise or counting numbers aloud, but a valid and useful test for this population is lacking.

SUMMARY

A framework for selecting the most appropriate test to assess breathlessness validly is proposed, and research needs are identified.

Service user perspectives on engagement in an occupational therapy-led pulmonary rehabilitation programme: A qualitative interview study

Introduction

Pulmonary rehabilitation (PR) is an intervention for people with chronic respiratory conditions. There are questions about which components are important to its success, including the nature of occupational therapy involvement. The aim of this research was to explore the experiences of people who had attended an occupational therapy-led PR programme in the United Kingdom to determine the most important components.

Method

Semi-structured telephone interviews were conducted with service users who had experience of a community-based PR programme. Interviews were transcribed verbatim. Data were analysed using the framework analysis method with three researchers contributing to the analysis.

Findings

Nine people took part in the interviews, with a mean age of 72 years. Four themes were identified which were organised around the concepts of Doing, Being, Becoming Belonging. These were 'Doing exercise and physical activity', 'being breathless', 'belonging as an individual within the group' and 'becoming a person who lives with Chronic Obstructive Pulmonary Disease'.

Conclusion

Doing physical activity, whilst coping with being breathless and belonging as an individual within a group can positively influence experiences and perceived outcomes during and after PR. These dimensions have the potential to shape occupation-focussed PR programmes and the occupational therapy contribution in this area of practice.

A New Normality Illuminated by Past and Present! A Qualitative Study: Experiences and Challenges of Everyday Life in Patients With Advanced Heart or Lung Failure

The aim of this study was to gain insight into the phenomena of everyday life as experienced and coped with by patients living with advanced heart or lung failure. We employed a qualitative design using a phenomenological hermeneutic approach. Data derived from 10 nursing consultations in a holistic setting. Ricoeur’s theory of interpretation inspired the text analysis. The study emphasizes time (past, present, and future) as an overall everyday life theme, playing an essential role associated with improvements or poor outcomes related to physical, mental, and intersubjective challenges. Patients accepted and lived with the challenges, experiencing changes, as transition, but also coped with their new normal, which involved improvements or poor outcomes, some invisible to the community. Assumptions about everyday life changed significantly, the changes possibly essential for intersubjective relations. A reflective approach, can help patients to evolve, using knowledge from the past and present to cope with the future.

Exploring patients' and health professionals' perspectives on health literacy needs in the context of chronic obstructive pulmonary disease

OBJECTIVE

Persons with chronic obstructive pulmonary disease (COPD) require complex follow-up by healthcare professionals (HCPs) and may experience several health literacy (HL) needs. This study aimed to explore such needs in people with COPD and the HCPs who care for them.

METHODS

From October 2016 to August 2017 a qualitative study with four focus groups (FG) were performed in people with COPD (n = 14) and three in multidisciplinary HCPs (n = 21). An inductive thematic analysis was used to investigate HL needs.

RESULTS

Four HL needs emerged: 1) strengthening the feeling of security; 2) combating the burden of insufficient knowledge on COPD and lack of informational flow; 3) supporting motivation for endurance and self-management; and 4) strengthening dignity.

DISCUSSION

This study highlights a gap between people with COPD who express important HL needs and HCPs' capabilities to care for these needs. For HCPs to increase HL in such cases, HCPs need to improve their own HL. It is essential to find solutions on how to improve HL in HCPs who care for people with COPD and to increase the availability of interventions that increase HL in COPD. Education programs, health organizations, and governments should be aware of HL needs in such situations.

Systematic review of effectiveness and quality assessment of patient education materials and decision aids for breathlessness

BACKGROUND

Around 10% of adults suffer from clinically significant breathlessness. High quality and actionable patient education materials (PEMs) and patient decision aids (PDAs) have an important role for shared decision making and patient self-management.

OBJECTIVE

To systematically assess the effectiveness of patient education materials (PEMs) and patient decision aids (PDAs) on clinical outcomes. Secondly, to assess the quality of PEMs and PDAs for breathlessness that are accessible online.

METHODS

A systematic review of PEM or PDA intervention for breathlessness published between 1 January 2010 and November 2020 was conducted. An environmental scan and quality assessment of publicly available PEMs and PDAs was also conducted.

RESULTS

Out of 2985 records, five studies were eligible for inclusion in this systematic review. Results of two randomised controlled trials suggest potential effectiveness of PEMs to improve patient reported outcomes and reduce healthcare utilization. In the environmental scan, 88 materials were included. Minimum reading age for most was high (Grade 10) and PEMs scored an average of 87% for understandability and 67% for actionability. Based on the DISCERN tool only 10 were classified as high quality.

CONCLUSION

There is a paucity of evidence on the effectiveness of PEMs and PDAs for improvement in breathlessness. There is a need to develop higher quality PEMs for breathlessness.

Patients’ and their caregivers’ experiences with regular, low-dose, sustained-release morphine for chronic breathlessness associated with COPD: a qualitative study

Introduction

Regular, low-dose, sustained-release morphine is effective in reducing chronic breathlessness in people with advanced disease, particularly in patients with chronic obstructive pulmonary disease (COPD). Despite experiencing a reduction in breathlessness, some patients choose not to continue long-term treatment.

Aim

This study aimed to explore patients’ and caregivers’ experiences with regular, low-dose, sustained-release morphine for chronic breathlessness associated with COPD.

Methods

A qualitative study embedded in a randomised controlled trial (RCT) of regular low-dose, sustained-release morphine for chronic breathlessness for people with COPD and modified Medical Research Council breathlessness scale 3–4. After completing the RCT or withdrawing, patients and their caregivers were invited to participate in interviews in their homes focused on their experiences with the trial medication while still blinded to the arm to which they had been allocated. Data analysis used a constant comparative method informed by the principles of grounded theory.

Results

Thirteen patients and nine caregivers participated. Four themes were identified: (1) Receptivity and knowledge; (2) Function as a priority; (3) Harmful and helpful side effects; and (4) Therapy-centred aspects. The concept of ‘net effect’ emerged from the interplay between themes, subthemes and the decision to continue taking sustained-release morphine during the trial and after trial completion.

Conclusion

Clinicians’ support and preconceived ideas about morphine influence the decision to commence sustained-release morphine. The hope for functional improvement is the great driver influencing positively the decision to take sustained-release morphine in the long term. The degree of symptom reduction, improved function, side-effects’ severity and caregivers’ availability creates a net effect driving patients’ decisions to continue or discontinue the medication.

Persisting breathlessness and activities reduced or ceased: a population study in older men

Introduction

Breathlessness is debilitating and increases in prevalence with age, with people progressively reducing their everyday activities to ‘self-manage’ it. This study aimed to evaluate the impact of breathlessness on function in terms of activities that have been reduced or ceased (‘compromised’) in older men.

Methods

A cross-sectional postal survey of Swedish 73-year-old man in the VAScular and Chronic Obstructive Lung disease study self-reporting on demographics, breathlessness (modified Medical Research Council (mMRC) scale, Dyspnoea-12, Multidimensional Dyspnea Scale) and its duration, anxiety/depression (Hospital Anxiety and Depression Scale), performance status (WHO Performance Status), everyday activities reduced/ceased and exertion.

Results

148/828 (17.9%) respondents reported breathlessness (mMRC >2), of whom 51.9% had reduced/ceased activities compared with 9.6% who did not. Physical activity was the most common activity reduced/ceased (48.0%) followed by sexual activity (41.2%) and social activities (37.8%). Of 16.0% of respondents with mMRC 3–4 talking on the phone was affected compared with only 2.9% of respondents with mMRC 2. Worsening breathlessness was associated with increasingly sedentary lifestyles and more limited function, those reporting reduced/ceased activities had an associated increase in reporting anxiety and depression. In adjusted analyses, breathlessness was associated with increased likelihood of activities being ceased overall as well as physical and sexual activities being affected separately.

Conclusion

Worsening breathlessness was associated with decreasing levels of self-reported physical activity, sexual activity and function. Overall, the study showed that people with persisting breathlessness modify their lifestyle to avoid it by reducing or ceasing a range of activities, seeking to minimise their exposure to the symptom.

Inspiratory Muscle Training Enhances Recovery Post COVID-19: A Randomised Controlled Trial

Background

Many people recovering from coronavirus disease 2019 (COVID-19) experience prolonged symptoms, particularly breathlessness. We urgently need to identify safe and effective COVID-19 rehabilitative strategies. The aim of the current study was to investigate the potential rehabilitative role of inspiratory muscle training (IMT).

Methods

281 adults (age 46.6±12.2 years; 88% female) recovering from self-reported COVID-19 (9.0±4.2 months post-acute infection) were randomised 4:1 to an 8-week IMT or a “usual care” waitlist control arm. Health-related quality-of-life and breathlessness questionnaires (King's Brief Interstitial Lung Disease (K-BILD) and Transition Dyspnoea Index (TDI)), respiratory muscle strength, and fitness (Chester Step Test) were assessed pre- and post-intervention. The primary end-point was K-BILD total score, with the K-BILD domains and TDI being key secondary outcomes.

Results

According to intention to treat, there was no difference between groups in K-BILD total score post-intervention (control: 59.5±12.4; IMT: 58.2±12.3; p<0.05) but IMT elicited clinically meaningful improvements in the K-BILD domains for breathlessness (control: 59.8±12.6; IMT: 62.2±16.2; p<0.05) and chest symptoms (control: 59.2±18.7; IMT: 64.5±18.2; p<0.05), along with clinically meaningful improvements in breathlessness according to TDI (control: 0.9±1.7 versus 2.0±2.0; p<0.05). IMT also improved respiratory muscle strength and estimated aerobic fitness.

Conclusions

IMT may represent an important home-based rehabilitation strategy for wider implementation as part of COVID-19 rehabilitative strategies. Given the diverse nature of long COVID, further research is warranted on the individual responses to rehabilitation; the withdrawal rate herein highlights that no one strategy is likely to be appropriate for all.

IMT can significantly improve breathlessness and respiratory muscle function in people with long COVID, and represents an effective, home-based rehabilitation strategy that could be widely implemented as part of COVID-19 recovery strategieshttps://bit.ly/3HiEyz0

Prevalence and severity of differing dimensions of breathlessness among elderly males in the population

Breathlessness is common in the general population. Existing data were obtained primarily with the uni-dimensional modified Medical Research Council breathlessness scale (mMRC) that does not assess intensities of unpleasantness nor physical, emotional and affective dimensions. The aim of this research was to determine the prevalence and intensity of these dimensions of breathlessness in elderly males and any associations with their duration, change over time and mMRC grade.

We conducted a population-based, cross-sectional study of 73-year-old males in a county in southern Sweden. Breathlessness was self-reported at one time point using a postal survey including the Dyspnea-12 (D-12), the Multidimensional Dyspnea Profile (MDP) and the mMRC. Presence of an increased dimension score was defined as a score ≥minimal clinically important difference for each dimension scale. Association with the mMRC, recalled change since age 65, and duration of breathlessness were analysed with linear regression.

Among 907 men, an increased dimension score was present in 17% (D-12 total score), 33% (MDP A1 unpleasantness), 19% (D-12 physical), 17% (MDP immediate perception), 10% (D-12 affective) and 17% (MDP emotional response). The unpleasantness and affective dimensions were strongly associated with mMRC≥3. Higher MDP and D-12 scores were associated with worsening of breathlessness since age 65, and higher MDP A1 unpleasantness was associated with breathlessness of less than 1 year duration.

Increased scores of several dimensions of breathlessness are prevalent in 73-year-old males and are positively correlated with mMRC scores, worsening of breathlessness after age 65, and duration of less than 1 year.

This first epidemiological study of multidimensional breathlessness shows that unpleasant, physical, affective and emotional experiences of breathlessness are common among elderly males, and are strongly associated with mMRC ≥3https://bit.ly/3EThp5a

Living with severe asthma: the role of perceived competence and goal achievement

OBJECTIVE

The overall aim of this study was to examine, among individuals living with severe asthma, the role of perceived competence in achieving their goals.

METHODS

Qualitative research methods were used to conduct in-depth semistructured interviews. Interviews were video and/or audio recorded, transcribed and analyzed inductively and deductively, informed by the self-determination theory construct of perceived competence. Thirty-six face-to-face interviews, lasting 1.5-4 h, were conducted across Australia.

RESULTS

Feeling competent to achieve asthma goals played a role in participants' ability to achieve broader goals. Their desire to achieve their broader goals was strongly driven by their perceived ability to master managing their condition, which at times required more than medical strategies. Two main themes were discerned from the analysis: (1) learning how to look after yourself: self-care is important and (2) reaching an agreement with severe asthma: being at one with the illness.

DISCUSSION

This study highlighted the influence of perceived competence on self-management and goal achievement in severe asthma. Healthcare providers could explore patients' perceived competence to set and achieve goals, as a self-management strategy. Future research should consider these findings when developing and implementing patient-driven, self-management interventions for those living with severe asthma.

Enabling patients in effective self-management of breathlessness in lung cancer: the neglected pillar of personalized medicine

Globally, engagement of patients in the self management of disease and symptom problems has become a health policy priority to improve health outcomes in cancer. Unfortunately, little attention has been focused on the provision of self-management support (SMS)in cancer and specifically for complex cancer symptoms such as breathlessness. Current management of breathlessness, which includes treatment of underlying disease, pharmacological agents to address comorbidities and opiates and anxiolytics to change perception and reduce the sense of breathing effort, is inadequate. In this perspective paper, we review the rationale and evidence for a structured, multicomponent SMS program in breathlessness including four components: breathing retraining, enhancing positive coping skills, optimizing exertional capacity and reducing symptom burden and health risks. The integration of SMS in routine lung cancer care is essential to improve breathlessness, reduce psychological distress, suffering and improve quality of life.

Breathlessness dimensions association with physical and mental quality of life: the population based VASCOL study of elderly men

Background

Breathlessness is a multidimensional symptom prevalent in elderly affecting many aspects of life. We aimed to determine how different dimensions of breathlessness are associated with physical and mental quality of life (QoL) in elderly men.

Methods

This was a cross-sectional, population-based analysis of 672 men aged 73 years in a Swedish county. Breathlessness was assessed using Dyspnoea-12 (D-12) and Multidimensional Dyspnoea Profile (MDP), and QoL using the Short Form 12 physical and mental scores. Scores were compared as z-scores across scales and analysed using multivariable linear regression, adjusted for smoking, body mass index and the presence of respiratory and cardiovascular disease.

Results

Worse breathlessness was related to worse physical and mental QoL across all the D-12 and MDP dimension scores. Physical QoL was most strongly associated with perceptional breathlessness scores, D-12 total and physical scores (95% CI −0.45 to −0.30). Mental QoL was more strongly influenced by affective responses, MDP emotional response score (95% CI −0.61 to −0.48). Head-to-head comparison of the instruments confirmed that D-12 total and physical scores most influenced physical QoL, while mental QoL was mostly influenced by the emotional responses captured by the MDP.

Conclusion

Breathlessness dimensions and QoL measures are associated differently. Physical QoL was most closely associated with sensory and perceptual breathlessness dimensions, while emotional responses were most strongly associated with mental QoL in elderly men. D-12 and MDP contribute complimentary information, where affective and emotional responses may be related to function, deconditioning and QoL.

Health service utilisation associated with chronic breathlessness: random population sample

BACKGROUND

Most health service utilisation studies are of people with specific diagnoses or demographic characteristics, and rarely of specific chronic symptoms. The aim of this study was to establish whether population-level health service utilisation increases in people with chronic breathlessness.

METHODS

A cross-sectional analysis was carried out of the South Australian Health Omnibus Survey 2017, a multi-stage, clustered area, systematic sampling survey of adults where questions are administered face-to-face in respondents' homes. Self-report of health service utilisation in the previous 3 months (medical consultations, emergency department, hospital admission), chronic breathlessness (severity, duration, modified Medical Research Council (mMRC) breathlessness scale) and demographic data were used to predict self-reported health service utilisation.

RESULTS

A total of 2898 people were included (49.0% male; median age 48.0 years (IQR 32.0-63.0); 64.1% educated beyond school; 55.4% in work; 73.5% had outpatient contact; 6.3% had a hospital admission in the previous 3 months). Chronic breathlessness (mMRC ≥1) was reported by 8.8% of respondents. In bivariable analyses, people with greater contact with health services were older, and a higher proportion were overweight/obese and had more severe chronic breathlessness. In multivariable analyses, chronic breathlessness and older age were positively associated with outpatient care and inpatient care, and people with chronic breathlessness were hospitalised for longer (incidence rate ratio 2.5; 95% CI 1.4-4.5).

CONCLUSION

There is a significant association between worse chronic breathlessness and increased health service utilisation. There is a need for greater understanding of factors that initiate contact with health services.

BreathEase: rationale, design and recruitment of a randomised trial and embedded mixed-methods study of a multiprofessional breathlessness service in early palliative care

BACKGROUND

The Munich Breathlessness Service has adapted novel support services to the German context, to reduce burden in patients and carers from breathlessness in advanced disease. It has been evaluated in a pragmatic fast-track randomised controlled trial (BreathEase; NCT02622412) with embedded qualitative interviews and postal survey. The aim of this article is to describe the intervention model and study design, analyse recruitment to the trial and compare sample characteristics with other studies in the field.

METHODS

Analysis of recruitment pathways and enrolment, sociodemographic and clinical characteristics of participants and carers.

RESULTS

Out of 439 people screened, 253 (58%) were offered enrolment and 183 (42%) participated. n=97 (70%) carers participated. 186 (42%) people did not qualify for inclusion, mostly because breathlessness could not be attributed to an underlying disease. All participants were self-referring; 60% through media sources. Eligibility and willingness to participate were associated to social networks and illness-related activities as recruitment routes. Mean age of participants was 71 years (51% women), with COPD (63%), chronic heart failure (8%), interstitial lung disease (9%), pulmonary hypertension (6%) and cancer (7%) as underlying conditions. Postal survey response rate was 89%. Qualitative interviews were conducted with 16 patients and nine carers.

CONCLUSION

The BreathEase study has a larger and more heterogeneous sample compared to other trials. The self-referral-based and prolonged recruitment drawing on media sources approximates real-world conditions of early palliative care. Integrating qualitative and quantitative components will allow a better understanding and interpretation of the results of the main effectiveness study.

Targeting exertional breathlessness to improve physical activity: the role of primary care

Primary care physicians (PCPs) play a crucial role in the diagnosis and management of chronic obstructive pulmonary disease (COPD). By working together with patients to target exertional breathlessness and increase physical activity, PCPs have an important role to play, early in the disease course, in improving patient outcomes in both the short and long term. In this article, we consider how physical activity affects disease progression from the PCP perspective. We discuss the role of pharmacological therapy, the importance of an holistic approach and the role of PCPs in assessing and promoting physical activity. The complexity and heterogeneity of COPD make it a challenging disease to treat. Patients' avoidance of activity, and subsequent decline in capacity to perform it, further impacts the management of the disease. Improving patient tolerance of physical activity, increasing participation in daily activities and helping patients to remain active are clear goals of COPD management. These may require an holistic approach to management, including pulmonary rehabilitation and psychological programmes in parallel with bronchodilation therapy, in order to address both physiological and behavioural factors. PCPs have an important role to optimise therapy, set goals and communicate the importance of maintaining physical activity to their patients. In addition, optimal treatment that addresses activity-related breathlessness can help prevent the downward spiral of inactivity and get patients moving again, to improve their overall health and long-term prognosis.

Self-management support preferences of people with asthma or chronic obstructive pulmonary disease: A systematic review and meta-synthesis of qualitative studies

OBJECTIVES

To synthesise findings from qualitative studies on the preferences of people with asthma or chronic obstructive pulmonary disease (COPD) for self-management support.

METHODS

A thematic synthesis of literature was carried out. Six databases (ASSIA, CINAHL, MEDLINE, PsycINFO, Psychology and the Behavioural Sciences and SSCI) were used to search for qualitative studies eliciting perspectives of adults with asthma and/or COPD on self-management support, published between May 2008 and April 2018.

RESULTS

A total of 968 articles were retrieved across databases, with 15 articles included in the synthesis. Three themes were identified: Types of Support described the range of supports valued by participants in the studies, particularly education provided by competent healthcare professionals; The Support Relationship highlighted the importance of a collaborative relationship with one's healthcare professional which was characterised by communication, trust and continuity over time and Accessibility identified the considerations of participants relating to physically accessible, prompt support which is provided in a format preferred by the individual.

DISCUSSION

Increased understanding of patients' preferences may provide insight which can be used to enhance engagement with self-management support. Further research needs to examine self-management support preferences outside the context of evaluating interventions for people with asthma/COPD and needs to address the optimal means of enhancing accessibility.

Self-care experiences of Pakistani patients with COPD and the role of family in self-care: A phenomenological inquiry

Self-care enables patients in improving quality of life and reducing hospital admissions. Research explored the experiences of patients about breathlessness, sleep problems and complication management in chronic obstructive pulmonary disease (COPD). However, the self-care experiences and the role of the family in self-care are underexplored. This study aimed to understand the self-care experiences of patients with COPD and explore the role of the family in self-care. An interpretive phenomenological inquiry was used, and 13 patients were interviewed in 2019 from two hospitals in Pakistan. The inclusion criteria were patients above 30 years of age at any stage of COPD, who received a confirmed diagnosis of COPD and were receiving the treatment, and engaged in self-care at their homes or communities. The interviews lasted for 35-60 min. Ricoeur's interpretation theory was used for data analysis comprising steps explanation, naive understanding and in-depth understanding. Self-care emerged as a complex individual and familial endeavour affected by personal, social and economic factors. Poverty was one of the core determinants of self-care. Patients emphasised the spiritual, cultural and traditional approaches to self-care. Future research is warranted to develop better understanding of spiritual and cultural self-care and how these dimensions of self-care affect patients' self-care behaviours.

Prevalence and Risk Factors of Breathlessness Across Canada: A National Retrospective Cohort Study in Home Care and Nursing Home Populations

CONTEXT

Breathlessness is a symptom associated with poor clinical outcomes and prognosis. Little is known about its long-term trends and associations with social factors including decline in social activities and caregiver distress.

OBJECTIVES

To describe factors associated with the prevalence of clinician-reported breathlessness across Canada among cohorts receiving home care or nursing home care.

METHODS

A retrospective observational cohort study of cross-sectional intake assessment data from Canadian interRAI Home Care and Nursing Home data sets. In each data set, we examined covariates associated with the presence of clinician-reported breathlessness using multivariate regression.

RESULTS

Between 2007 and 2018, we identified 1,317,117 and 469,709 individuals from the home care and nursing home data sets, respectively. Over two-thirds were aged >75 and over 60% were women. Breathlessness was present at intake in 26.0% of the home care and 8.2% of the nursing home cohorts. Between 2007 and 2018, prevalence of breathlessness increased by 10% for the home care cohort, while remaining relatively constant in nursing homes. Covariates associated with increased odds of having clinician-reported breathlessness at intake in both cohorts were moderate-severe impairment with activities of daily living, being male, older age, high pain scores, signs of depression, and decline in social activities. In the home care cohort, the presence of breathlessness was associated with a greater odds of caregiver distress (odds ratio = 1.19, 95% CI: 1.18-1.20).

CONCLUSION

The prevalence of clinician-reported breathlessness is higher in home care than in nursing home populations, the former having risen by 10% over the decade. Prevalence of breathlessness is associated with decline in social activities and caregiver distress. Enhanced supports may be required to meet increasing patient need in the community.

VAScular and Chronic Obstructive Lung disease (VASCOL): a longitudinal study on morbidity, symptoms and quality of life among older men in Blekinge county, Sweden

PURPOSE

Despite data showing breathlessness to be more prevalent in older adults, we have little detail about the severity or multidimensional characteristics of breathlessness and other self-reported measures (such as quality of life and other cardiorespiratory-related symptoms) in this group at the population level. We also know little about the relationship between multidimensional breathlessness, other symptoms, comorbidities and future clinical outcomes such as quality of life, hospitalisation and mortality. This paper reports the design and descriptive findings from the first two waves of a longitudinal prospective cohort study in older adults.

PARTICIPANTS

Between 2010 and 2011, 1900 men in a region in southern Sweden aged 65 years were invited to attend for VAScular and Chronic Obstructive Lung disease (VASCOL) baseline (Wave 1) assessments which included physiological measurements, blood sampling and a self-report survey of lifestyle and previous medical conditions. In 2019, follow-up postal survey data (Wave 2) were collected with additional self-report measures for breathlessness, other symptoms and quality of life. At each wave, data are cross-linked with nationwide Swedish registry data of diseases, treatment, hospitalisation and cause of death.

FINDINGS TO DATE

1302/1900 (68%) of invited men participated in Wave 1, which include 56% of all 65-year-old men in the region. 5% reported asthma, 2% chronic obstructive pulmonary disease, 56% hypertension, 10% diabetes and 19% had airflow limitation. The VASCOL cohort had comparable characteristics to those of similarly aged men in Sweden. By 2019, 109/1302 (8.4%) had died. 907/1193 (76%) of the remainder participated in Wave 2. Internal data completeness of 95% or more was achieved for most Wave 2 measures.

FUTURE PLANS

A third wave will be conducted within 4 years, and the cohort will be followed through repeated follow-ups planned every fourth year, as well as national registry data of diagnosis, treatments and cause of death.
