Breathlessness clinics within specialist palliative care settings can improve the quality of life and functional capacity of patients with lung cancer

Comprehensive Pulmonary Rehabilitation for Patients with Malignant Pleural Mesothelioma: A Feasibility Pilot Study

Malignant pleural mesothelioma (MPM) represents a significant health burden, with limited treatment options and poor prognosis. Despite advances in pharmacological and surgical interventions, the role of rehabilitation in MPM management remains underexplored. This study aims to assess the feasibility of a tailored pulmonary rehabilitation intervention addressing physical and respiratory function in MPM patients. A prospective pilot study was conducted on surgically treated MPM patients referred to a cardiopulmonary rehabilitation service. The intervention comprised multidisciplinary educational sessions, physical rehabilitation, and respiratory physiotherapy. Feasibility was evaluated based on dropout rates, adherence to the rehabilitation program, safety, and patient-reported outcomes. Twelve patients were initially enrolled, with seven completing the study. High adherence to physical (T1: 93.43%, T2: 82.56%) and respiratory (T1: 96.2%, T2: 92.5%) rehabilitation was observed, with minimal adverse events reported. Patient satisfaction remained high throughout the study (GPE scores at T1: 1.83 ± 1.17; T2: 2.0 ± 1.15), with improvements noted in physical function, pain management, and health-related quality of life. However, some issues, such as time constraints and lack of continuous supervision, were reported by participants. This pilot study demonstrates the feasibility and potential benefits of a tailored pulmonary rehabilitation intervention in MPM patients. Despite its promising outcomes, further research with larger samples is warranted to validate its efficacy and integrate rehabilitation as a component into the multidisciplinary management of MPM.

Timely Assessment of Breathing-Related Distress in Community Palliative Care: A Multidisciplinary Collaborative Quality Improvement Project

Background: Breathlessness is a common symptom for palliative patients that can cause distress and decrease function and quality of life. Palliative care services in Australia aim to routinely assess patients for breathing-related distress, but timely reassessment is not always achieved. Objective: To improve the timeliness of breathlessness reassessment in a home-based community palliative care service in New South Wales for people with moderate-to-severe breathing-related distress. Breathing-related distress was defined as a Symptom Assessment Score for "breathing problems" of four or more. Methods: This collaborative quality improvement (QI) project between SPHERE Palliative Care CAG, Stanford University mentors, and a Sydney metropolitan specialist palliative care service included a: (1) retrospective chart audit; (2) cause and effect analyses using a fishbone diagram; (3) development and implementation of key drivers and interventions; and (4) a pre-and-post evaluation of the timeliness of reassessment of breathing-related distress and changes in Symptom Assessment Scale scores for "breathing problems." Results: Key interventions included multidisciplinary education sessions to facilitate buy-in, with nurses as case managers responsible for breathlessness reassessment and documentation of scores, access and training in electronic palliative care data entry software, fortnightly monitoring and reporting of breathing-related distress scores, and development of an educational flowchart. The proportion of patients reassessed within seven days of an initial nursing assessment of moderate-to-severe breathing-related distress increased from 34% at baseline to 92% at six months. Conclusion: A local QI project increased the proportion of patients with a timely reassessment of their breathing-related distress in a community palliative care service.

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.

An online international comparison of palliative care identification in primary care using the Surprise Question

BACKGROUND

The Surprise Question ('Would I be surprised if this patient died within 12 months?') identifies patients in the last year of life. It is unclear if 'surprised' means the same for each clinician, and whether their responses are internally consistent.

AIM

To determine the consistency with which the Surprise Question is used.

DESIGN

A cross-sectional online study of participants located in Belgium, Germany, Italy, The Netherlands, Switzerland and UK. Participants completed 20 hypothetical patient summaries ('vignettes'). Primary outcome measure: continuous estimate of probability of death within 12 months (0% [certain survival]-100% [certain death]). A threshold (probability estimate above which Surprise Question responses were consistently 'no') and an inconsistency range (range of probability estimates where respondents vacillated between responses) were calculated. Univariable and multivariable linear regression explored differences in consistency. Trial registration: NCT03697213.

SETTING/PARTICIPANTS

Registered General Practitioners (GPs). Of the 307 GPs who started the study, 250 completed 15 or more vignettes.

RESULTS

Participants had a consistency threshold of 49.8% (SD 22.7) and inconsistency range of 17% (SD 22.4). Italy had a significantly higher threshold than other countries (p = 0.002). There was also a difference in threshold levels depending on age of clinician, for every yearly increase, participants had a higher threshold. There was no difference in inconsistency between countries (p = 0.53).

CONCLUSIONS

There is variation between clinicians regarding the use of the Surprise Question. Over half of GPs were not internally consistent in their responses to the Surprise Question. Future research with standardised terms and real patients is warranted.

Assessment of the effects of a multi-component, individualized physiotherapy program in patients receiving hospice services in the home

BACKGROUND

The interest in physiotherapy programs for individuals in hospice is increasing. The aim of our study was to assess the impact of a multi-component, individualized physiotherapy program on the functional and emotional conditions and quality of life of patients receiving hospice services in the home.

METHODS

The study included 60 patients (mean 66.3 years) receiving hospice services in the home. A model of a physiotherapy program was designed, including breathing, strengthening, transfer, gait, balance, functional, and ergonomic exercises, as well as an adaptation of the patient's living environment to functional needs. The tests were performed before and after the intervention. The study used the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, the World Health Organization Quality of Life - Bref (WHOQOL-BREF), the Visual Analogue Scale (VAS) pain scale, the Tinetti POMA Scale, and the Geriatric Depression Scale (GDS). To enable comparison of our results worldwide, a set of International Classification of Functioning, Disability and Health (ICF) categories was used.

RESULTS

The average functional level of the ADL (mean 2.9) and the IADL (mean 11.9), as well as the WHOQOL-BREF (mean 46.4) of the patients before the intervention were low, whereas the intensity of pain (VAS mean 5.8), the risk of falling (Tinetti mean 8.2), and depression (GDS mean 16.7) were recorded as high. After the completion of the intervention program, a significant improvement was found in the ADL (mean 4.0), IADL (mean 13.9), WHOQOL-BREF (mean 52.6), VAS (mean 5.1), risk of falling (Tinetti mean 12.3), and GDS (mean 15.7) scores.

CONCLUSIONS

The physiotherapeutic intervention had a significant impact on improving the performance of ADL, as well as the emotional state and quality of life of patients receiving hospice services in the home. The results of our research provide evidence of the growing need for physiotherapy in individuals in hospice and for comprehensive assessment by means of ICF.

Identification and Assessment of Breathlessness in Clinical Practice: A Systematic Review and Narrative Synthesis

CONTEXT

Breathlessness is common in chronic conditions but often goes unidentified by clinicians. It is important to understand how identification and assessment of breathlessness occurs across health care settings, to promote routine outcome assessment and access to treatment.

OBJECTIVE

The objective of this study was to summarize how breathlessness is identified and assessed in adults with chronic conditions across different health care settings.

METHODS

This is a systematic review and descriptive narrative synthesis (PROSPERO registration: CRD42018089782). Searches were conducted on Medline, PsycINFO, Cochrane Library, Embase, and CINAHL (2000-2018) and reference lists. Screening was conducted by two independent reviewers, with access to a third, against inclusion criteria. Data were extracted using a bespoke proforma.

RESULTS

Ninety-seven studies were included, conducted in primary care (n = 9), secondary care (n = 53), and specialist palliative care (n = 35). Twenty-five measures of identification and 41 measures of assessment of breathlessness were used. Primary and secondary care used a range of measures to assess breathlessness severity, cause, and impact for people with chronic obstructive pulmonary disease. Specialist palliative care used measures assessing broader symptom severity and function with less focus on overall quality of life. Few studies were identified from primary care.

CONCLUSION

Various measures were identified, reflective of the setting's purpose. However, this highlights missed opportunities for breathlessness management across settings; primary care is particularly well placed to diagnose and support breathlessness. The chronic obstructive pulmonary disease approach (where symptoms and quality of life are part of disease management) could apply to other conditions. Better documentation of holistic patient-reported measures may drive service improvement in specialist palliative care.

"I've found it's very meaningful work": Perspectives of physiotherapists providing palliative care in Ontario

OBJECTIVES

This study aimed to describe insights from interviews about the experience of physiotherapists providing palliative care in Ontario and their perceptions of the role and value of physiotherapists' involvement in palliative care.

METHODS

We conducted interviews with physiotherapists in Ontario, Canada (n = 14), and received emailed submissions from two others (one physiotherapist and one physiotherapy student) with current or recent practice experience in palliative care. We conducted inductive thematic analysis of the interview data and emailed submissions.

RESULTS

Participants' reflections were categorized into three major themes: perceived value of the contribution of physiotherapists in palliative care; the experience of providing physiotherapy in palliative care; and reflections on the palliative care system. Participants described their role in palliative care as diverse, driven by patient goals and focused on the experience of patients and families. Participants perceived a high value in collaborative networks for supporting them to fulfill their role in palliative care settings. Participants also recommended efforts to increase awareness of the potential for physiotherapists to contribute to palliative care.

CONCLUSIONS

The findings confirm those of research in other jurisdictions and extend our understanding of the value and meaningfulness of physiotherapy in palliative care, to patients, families, and physiotherapists themselves.

Holistic services for people with advanced disease and chronic or refractory breathlessness: a mixed-methods evidence synthesis

Background

Breathlessness is a common and distressing symptom of many advanced diseases, affecting around 2 million people in the UK. Breathlessness increases with disease progression and often becomes chronic or refractory. Breathlessness-triggered services that integrate holistic assessment and specialist palliative care input as part of a multiprofessional approach have been developed for this group, offering tailored interventions to support self-management and reduce distress.

Objectives

The aim was to synthesise evidence on holistic breathlessness services for people with advanced disease and chronic or refractory breathlessness. The objectives were to describe the structure, organisation and delivery of services, determine clinical effectiveness, cost-effectiveness and acceptability, identify predictors of treatment response, and elicit stakeholders’ evidence-based priorities for clinical practice, policy and research.

Design

The mixed-methods evidence synthesis comprised three components: (1) a systematic review to determine the clinical effectiveness, cost-effectiveness and acceptability of holistic breathlessness services; (2) a secondary analysis of pooled individual data from three trials to determine predictors of clinical response; and (3) a transparent expert consultation (TEC), comprising a stakeholder workshop and an online consensus survey, to identify stakeholders’ priorities.

Results

Thirty-seven papers reporting on 18 holistic breathlessness services were included in the systematic review. Most studies enrolled people with thoracic cancer, were delivered over 4–6 weeks, and included breathing training, relaxation techniques and psychological support. Meta-analysis demonstrated significant reductions in the Numeric Rating Scale (NRS) distress due to breathlessness, significant reductions in the Hospital Anxiety and Depressions Scale (HADS) depression scores, and non-significant reductions in the Chronic Respiratory Disease Questionnaire (CRQ) mastery and HADS anxiety, favouring the intervention. Recipients valued education, self-management interventions, and expertise of the staff in breathlessness and person-centred care. Evidence for cost-effectiveness was limited and inconclusive. The responder analysis (n = 259) revealed baseline CRQ mastery and NRS distress to be strong predictors of the response to breathlessness services assessed by these same measures, and no significant influence from baseline breathlessness intensity, patient diagnosis, lung function, health status, anxiety or depression. The TEC elicited 34 priorities from stakeholders. Seven priorities received high agreement and consensus, reflecting stakeholders’ (n = 74) views that services should be person-centred and multiprofessional, share their breathlessness management skills with others, and recognise the roles and support needs of informal carers.

Limitations

The evidence synthesis draws predominantly from UK services and may not be generalisable to other settings. Some meta-analyses were restricted by reporting biases and statistical heterogeneity.

Conclusions

Despite heterogeneity in composition and delivery, holistic breathlessness services are highly valued by recipients and can lead to significant improvements in the distress caused by breathlessness and depression. Outcomes of improved mastery and reduced distress caused by breathlessness are not influenced by patient diagnosis, lung function or health status. Stakeholders highlighted the need for improved access to person-centred, multiprofessional breathlessness services and support for informal carers.

Future work

Our research suggests that key therapeutic components of holistic breathlessness services be considered in clinical practice and models of delivery and educational strategies to address stakeholders’ priorities tested.

An online international comparison of thresholds for triggering a negative response to the "Surprise Question": a study protocol

BACKGROUND

The Surprise Question (SQ) "would I be surprised if this patient were to die in the next 12 months?" has been suggested to help clinicians, and especially General Practitioners (GPs), identify people who might benefit from palliative care. The prognostic accuracy of this approach is unclear and little is known about how GPs use this tool in practice. Are GPs consistent, individually and as a group? Are there international differences in the use of the tool? Does including the alternative Surprise Question ("Would I be surprised if the patient were still alive after 12 months?") alter the response? What is the impact on the treatment plan in response to the SQ? This study aims to address these questions.

METHODS

An online study will be completed by 600 (100 per country) registered GPs. They will be asked to review 20 hypothetical patient vignettes. For each vignette they will be asked to provide a response to the following four questions: (1) the SQ [Yes/No]; (2) the alternative SQ [Yes/No]; (3) the percentage probability of dying [0% no chance - 100% certain death]; and (4) the proposed treatment plan [multiple choice]. A "surprise threshold" for each participant will be calculated by comparing the responses to the SQ with the probability estimates of death. We will use linear regression to explore any differences in thresholds between countries and other clinician-related factors, such as years of experience. We will describe the actions taken by the clinicians and explore the differences between groups. We will also investigate the relationship between the alternative SQ and the other responses. Participants will receive a certificate of completion and the option to receive feedback on their performance.

DISCUSSION

This study explores the extent to which the SQ is consistently used at an individual, group, and national level. The findings of this study will help to understand the clinical value of using the SQ in routine practice.

Holistic services for people with advanced disease and chronic breathlessness: a systematic review and meta-analysis

BACKGROUND

Breathlessness is a common, distressing symptom in people with advanced disease and a marker of deterioration. Holistic services that draw on integrated palliative care have been developed for this group. This systematic review aimed to examine the outcomes, experiences and therapeutic components of these services.

METHODS

Systematic review searching nine databases to June 2017 for experimental, qualitative and observational studies. Eligibility and quality were independently assessed by two authors. Data on service models, health and cost outcomes were synthesised, using meta-analyses as indicated. Data on recipient experiences were synthesised thematically and integrated at the level of interpretation and reporting.

RESULTS

From 3239 records identified, 37 articles were included representing 18 different services. Most services enrolled people with thoracic cancer, involved palliative care staff and comprised 4-6 contacts over 4-6 weeks. Commonly used interventions included breathing techniques, psychological support and relaxation techniques. Meta-analyses demonstrated reductions in Numeric Rating Scale distress due to breathlessness (n=324; mean difference (MD) -2.30, 95% CI -4.43 to -0.16, p=0.03) and Hospital Anxiety and Depression Scale (HADS) depression scores (n=408, MD -1.67, 95% CI -2.52 to -0.81, p<0.001) favouring the intervention. Statistically non-significant effects were observed for Chronic Respiratory Questionnaire (CRQ) mastery (n=259, MD 0.23, 95% CI -0.10 to 0.55, p=0.17) and HADS anxiety scores (n=552, MD -1.59, 95% CI -3.22 to 0.05, p=0.06). Patients and carers valued tailored education, self-management interventions and expert staff providing person-centred, dignified care. However, there was no observable effect on health status or quality of life, and mixed evidence around physical function.

CONCLUSION

Holistic services for chronic breathlessness can reduce distress in patients with advanced disease and may improve psychological outcomes of anxiety and depression. Therapeutic components of these services should be shared and integrated into clinical practice.

Palliative care and nursing support for patients experiencing dyspnoea

To investigate the association between the type of support provided by nurses for dyspnoea and palliative care practice in Japan, a cross-sectional questionnaire survey was conducted in 2015. Of the 535 questionnaires sent to nurses working at 22 designated cancer hospitals, 344 were returned. The questionnaire assessed the demographic characteristics of the nurses, nursing support for dyspnoea, and palliative care practice measured by the 'Palliative care self-reported practices scale'. Multivariate analysis showed that the domains of palliative care practice influenced the provision of nursing support for patients with dyspnoea. In conclusion, palliative care practice is important for supporting patients with dyspnoea, and nurses should possess the requisite knowledge and skills to deliver this care appropriately.

Physiotherapy programme reduces fatigue in patients with advanced cancer receiving palliative care: randomized controlled trial

Purpose

Cancer-related fatigue (CRF) is a common and relevant symptom in patients with advanced cancer that significantly decreases their quality of life. The aim of this study was to evaluate the effect of a physiotherapy programme on CRF and other symptoms in patients diagnosed with advanced cancer.

Methods

The study was designed as a randomized controlled trial. Sixty patients diagnosed with advanced cancer receiving palliative care were randomized into two groups: the treatment group (n = 30) and the control group (n = 30). The therapy took place three times a week for 2 weeks. The 30-min physiotherapy session included active exercises, myofascial release and proprioceptive neuromuscular facilitation (PNF) techniques. The control group did not exercise. The outcomes included Brief Fatigue Inventory (BFI), Edmonton Symptom Assessment Scale (ESAS) and satisfaction scores.

Results

The exercise programme caused a significant reduction in fatigue scores (BFI) in terms of severity of fatigue and its impact on daily functioning. In the control group, no significant changes in the BFI were observed. Moreover, the physiotherapy programme improved patients’ general well-being and reduced the intensity of coexisting symptoms such as pain, drowsiness, lack of appetite and depression. The analysis of satisfaction scores showed that it was also positively evaluated by patients.

Conclusion

The physiotherapy programme, which included active exercises, myofascial release and PNF techniques, had beneficial effects on CRF and other symptoms in patients with advanced cancer who received palliative care. The results of the study suggest that physiotherapy is a safe and effective method of CRF management.

Is a specialist breathlessness service more effective and cost-effective for patients with advanced cancer and their carers than standard care? Findings of a mixed-method randomised controlled trial

BACKGROUND

Breathlessness is common in advanced cancer. The Breathlessness Intervention Service (BIS) is a multi-disciplinary complex intervention theoretically underpinned by a palliative care approach, utilising evidence-based non-pharmacological and pharmacological interventions to support patients with advanced disease. We sought to establish whether BIS was more effective, and cost-effective, for patients with advanced cancer and their carers than standard care.

METHODS

A single-centre Phase III fast-track single-blind mixed-method randomised controlled trial (RCT) of BIS versus standard care was conducted. Participants were randomised to one of two groups (randomly permuted blocks). A total of 67 patients referred to BIS were randomised (intervention arm n = 35; control arm n = 32 received BIS after a two-week wait); 54 completed to the key outcome measurement. The primary outcome measure was a 0 to 10 numerical rating scale for patient distress due to breathlessness at two-weeks. Secondary outcomes were evaluated using the Chronic Respiratory Questionnaire, Hospital Anxiety and Depression Scale, Client Services Receipt Inventory, EQ-5D and topic-guided interviews.

RESULTS

BIS reduced patient distress due to breathlessness (primary outcome: -1.29; 95% CI -2.57 to -0.005; P = 0.049) significantly more than the control group; 94% of respondents reported a positive impact (51/53). BIS reduced fear and worry, and increased confidence in managing breathlessness. Patients and carers consistently identified specific and repeatable aspects of the BIS model and interventions that helped. How interventions were delivered was important. BIS legitimised breathlessness and increased knowledge whilst making patients and carers feel 'not alone'. BIS had a 66% likelihood of better outcomes in terms of reduced distress due to breathlessness at lower health/social care costs than standard care (81% with informal care costs included).

CONCLUSIONS

BIS appears to be more effective and cost-effective in advanced cancer than standard care.

WITHDRAWN: Non-pharmacological interventions for breathlessness in advanced stages of malignant and non-malignant diseases

This review is now out of date although it is correct as of the date of publication [Issue 2, 2008]. The authors are developing a new protocol which will replace this review. Publication of the protocol is expected in 2014, and serves to update the existing review and incorporate the latest evidence into a new Cochrane Review. The latest version of this review (available in 'Other versions' tab on The Cochrane Library) may still be useful to readers until the new review is published.

In 2016, the replacement review titled 'Non‐pharmacological interventions for breathlessness in advanced stages of malignant and non‐malignant diseases' was deregistered and split into four separate reviews of individual interventions: Respiratory interventions for breathlessness in adults with advanced diseases; Physical interventions for breathlessness in adults with advanced diseases; Cognitive‐emotional interventions for breathlessness in adults with advanced diseases; Multi‐dimensional interventions for breathlessness in adults with advanced diseases.

At September 2020, these replacement titles were deregistered (Multi‐dimensional interventions) or the protocols withdrawn (Cognitive‐emotional interventions; Multi‐dimensional interventions; Respiratory interventions) as they did not meet Cochrane standards or expectations.

The editorial group responsible for this previously published document have withdrawn it from publication.

Individual experiences and impacts of a physiotherapist-led, non-pharmacological breathlessness programme for patients with intrathoracic malignancy: a qualitative study

BACKGROUND

Non-pharmacological breathlessness management programmes have been shown to be beneficial in the management of lung cancer-related dyspnoea for more than 10 years. What is not so clear is how they work.

AIM

To evaluate how patients with intrathoracic malignancy (lung cancer or pleural mesothelioma) undergoing the non-pharmacological breathlessness management programmes benefited from the programme, using a qualitative methodology.

DESIGN AND SETTING

Consecutive patients completing the programme were invited to be interviewed (semi-structured and audio-recorded) about their experiences of the programme, what had helped them and how. Interviews were transcribed and analysed using interpretative phenomenological analysis.

RESULTS

Nine patients were interviewed. Seven major themes emerged, they are summarised as follows: (1) Mixed prior expectations of the programme, (2) flexibility of delivery and additional support needs, (3) physiotherapist attributes and skills in developing an effective helping relationship, (4) adoption of new techniques, (5) the effects and impact of the programme and new techniques, (6) difficulties and barriers to achieving change and (7) facing an uncertain future beyond the programme.

CONCLUSION

The non-pharmacological breathlessness management programme appears to offer a wide range of benefits to patients, including improving functional capacity, coping strategies and self-control. Such benefits are most likely to be due to a combination of breathing control, activity management and the therapist qualities.

Breathing exercises improve post-operative pulmonary function and quality of life in patients with lung cancer: A meta-analysis

Previous research has shown that breathing exercises may improve the prognosis and health status in patients with lung cancer by enhancing pulmonary function and quality of life (QOL). However, individually published results are inconclusive. The aim of the present meta-analysis was to evaluate the clinical value of breathing exercises on post-operative pulmonary function and QOL in patients with lung cancer. A literature search of Pubmed, Embase, the Web of Science and CBM databases was conducted from their inception through to October 2012. Crude standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to assess the effect of breathing exercises. A total of eight clinical studies were ultimately included with 398 lung cancer patients. When all the eligible studies were pooled into the meta-analysis, there was a significant difference between the pre-intervention and post-intervention results of breathing exercises on post-operative pulmonary function; forced expiratory volume in 1 sec (FEV1): SMD, 3.37; 95% CI, 1.97–4.77; P<0.001; FEV1/FVC: SMD, 1.77; 95% CI, 0.15–3.39; P=0.032). Furthermore, the QOL in patients with lung cancer was significantly improved following the intervention with breathing exercises; there were significant differences between the pre-intervention and post-intervention results on the ability of self-care in daily life (SMD, −1.00; 95% CI, −1.467 to −0.52; P<0.001), social activities (SMD, −0.94; 95% CI, −1.73 to −0.15; P=0.02), symptoms of depression (SMD, −0.91; 95% CI, −1.25 to −0.57; P<0.001) and symptoms of anxiety (SMD, −0.91; 95% CI, −1.20 to −0.63; P<0.001). Results from the present meta-analysis suggest that breathing exercises may significantly improve post-operative pulmonary function and QOL in patients with lung cancer.

Nonpharmacological interventions for managing respiratory symptoms in lung cancer

Patients with lung cancer experience significant symptom burden, particularly symptoms of a respiratory nature. Such symptom burden can be distressing for patients and negatively impact their functional status and quality of life. The aim of this review is to evaluate studies of nonpharmacological and noninvasive interventions for the management of respiratory symptoms experienced by patients with lung cancer. In total, 13 studies met the inclusion criteria for this review and included 1383 participants of which 1296 were lung cancer patients. The most frequently assessed and reported symptom was breathlessness (n = 9 studies). Cough and haemoptysis were reported in one study. A variety of outcome measurement tools were used and a broad range of intervention strategies evaluated. Lack of consistency between studies impinged on the ability to combine studies. It is not possible to draw any firm conclusion as to the effectiveness of nonpharmacological interventions for the management of respiratory symptoms in lung cancer. Nonpharmacological interventions may well have an important role to play in the management of some of the respiratory symptoms (or combinations of respiratory symptoms), but more work of higher quality is necessary in the future.

Study protocol: Phase III single-blinded fast-track pragmatic randomised controlled trial of a complex intervention for breathlessness in advanced disease

Background

Breathlessness in advanced disease causes significant distress to patients and carers and presents management challenges to health care professionals. The Breathlessness Intervention Service (BIS) seeks to improve the care of breathless patients with advanced disease (regardless of cause) through the use of evidence-based practice and working with other healthcare providers. BIS delivers a complex intervention (of non-pharmacological and pharmacological treatments) via a multi-professional team. BIS is being continuously developed and its impact evaluated using the MRC's framework for complex interventions (PreClinical, Phase I and Phase II completed). This paper presents the protocol for Phase III.

Methods/Design

Phase III comprises a pragmatic, fast-track, single-blind randomised controlled trial of BIS versus standard care. Due to differing disease trajectories, the service uses two broad service models: one for patients with malignant disease (intervention delivered over two weeks) and one for patients with non-malignant disease (intervention delivered over four weeks). The Phase III trial therefore consists of two sub-protocols: one for patients with malignant conditions (four week protocol) and one for patients with non-malignant conditions (eight week protocol). Mixed method interviews are conducted with patients and their lay carers at three to five measurement points depending on randomisation and sub-protocol. Qualitative interviews are conducted with referring and non-referring health care professionals (malignant disease protocol only). The primary outcome measure is 'patient distress due to breathlessness' measured on a numerical rating scale (0-10). The trial includes economic evaluation. Analysis will be on an intention to treat basis.

Discussion

This is the first evaluation of a breathlessness intervention for advanced disease to have followed the MRC framework and one of the first palliative care trials to use fast track methodology and single-blinding. The results will provide evidence of the clinical and cost-effectiveness of the service, informing its longer term development and implementation of the model in other centres nationally and internationally. It adds to methodological developments in palliative care research where complex interventions are common but evidence sparse.

Extending palliative care to patients with respiratory disease

This article describes the importance of improving access to palliative care services of patients with advanced chronic respiratory disease. It outlines their needs, the challenges involved in meeting them and ways in which current models of care may need to be modified to increase access.

A community population survey of prevalence and severity of dyspnea in adults

Given the progress in the symptomatic treatment of breathlessness, and the physical and psychological morbidity associated with chronic breathlessness, estimates of the size of the population that may benefit from better support become imperative. Prevalence estimates have varied widely (0.9% of clinical encounters to 32%) and have largely relied only on respondents who used clinical services. Whole-of-population approaches may be able to define better the "true" prevalence of chronic breathlessness and quantify exertion limited by breathlessness. The aim of this study was to estimate population levels of chronic breathlessness, severity of limits to exercise, and demographic predictors of the presence of breathlessness. A whole-of-population face-to-face survey method (n=8,396) in South Australia was used, directly standardized for age, gender, country of birth, and rurality. Respondents were asked about breathlessness and levels of exertion causing breathlessness for at least three of the last six months using a modified Medical Research Council dyspnea scale. Univariate and multivariate analyses identify the demographic characteristics of people more likely to experience chronic breathlessness. With a participation rate of 65.3%, 8.9% of respondents had breathlessness that chronically limited exertion. Significant associations with chronic breathlessness in multivariate analysis included female sex (P<0.001), not working full time (P<0.001), low income (P=0.007), and older age (P=0.031). There are significant levels of chronic breathlessness in the community. Given the prevalence, it is feasible to explore the onset of breathlessness, the underlying etiologies and subsequent health service utilization, and health consequences.

The feasibility of a single-blinded fast-track pragmatic randomised controlled trial of a complex intervention for breathlessness in advanced disease

Background

The Breathlessness Intervention Service is a novel service for patients with intractable breathlessness regardless of aetiology. It is being evaluated using the Medical Research Council's framework for the evaluation of complex interventions. This paper describes the feasibility results of Phase II: a single-blinded fast-track pragmatic randomised controlled trial.

Methods

A single-blinded fast-track pragmatic randomised controlled trial was conducted for patients with chronic obstructive pulmonary disease referred to the service. Patients were randomised to either receive the intervention immediately for an eight-week period, or receive the intervention after an eight-week period on a waiting list during which time they received standard care. Outcomes examined included: response rates to the trial; response rates to the individual questionnaires and items; comments relating to the trial functioning made during interviews with patients, carers, referrers and service providers; and, researcher fieldwork notes.

Results

16 of the 20 eligible patients agreed to participate in a recruitment visit (16/20); 14 respondents went on to complete a recruitment visit/baseline interview. The majority of those who completed a recruitment visit/baseline interview completed the RCT protocol (13/14); 12 of their carers were recruited and completed the protocol. An unblinding rate of 6/25 respondents (patients and carers) was identified. Missing data were minimal and only one patient was lost to follow up. The fast-track trial methodology proved feasible and acceptable. Two of the baseline/outcome measures proved unsuitable: the WHO performance scale and the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW).

Conclusion

This study adds to the evidence that fast-track randomised controlled trials are feasible and acceptable in evaluations of palliative care interventions for patients with non-malignant conditions. Reasonable response rates and low attrition rates were achieved. Further, with adequate preparation of the research and randomisation teams, clinicians, and responders, and effective liaison with the clinicians, single-blinding proved possible. Methods were identified to reduce unblinding through careful attention to the type of data collected at unblinded measurement points; the content of interviews should be carefully considered when designing blinded-trial protocols.

Does palliative home oxygen improve dyspnoea? A consecutive cohort study

Palliative oxygen for refractory dyspnoea is frequently prescribed, even when the criteria for long-term home oxygen (based on survival, rather than the symptomatic relief of breathlessness) are not met. Little is known about how palliative home oxygen affects symptomatic breathlessness. A 4-year consecutive cohort from a regional community palliative care service in Western Australia was used to compare baseline breathlessness before oxygen therapy with dyspnoea sub-scales on the symptom assessment scores (SAS; 0-10) 1 and 2 weeks after the introduction of oxygen. Demographic and clinical characteristics of people who responded were included in a multi-variable logistic regression model. Of the study population (n = 5862), 21.1% (n = 1239) were prescribed oxygen of whom 413 had before and after data that could be included in this analysis. The mean breathlessness before home oxygen was 5.3 (SD 2.5; median 5; range 0-10). There were no significant differences overall at 1 or 2 weeks (P = 0.28) nor for any diagnostic sub-groups. One hundred and fifty people (of 413) had more than a 20% improvement in mean dyspnoea scores. In multi-factor analysis, neither the underlying diagnosis causing breathlessness nor the demographic factors predicted responders at 1 week. Oxygen prescribed on the basis of breathlessness alone across a large population predominantly with cancer does not improve breathlessness for the majority of people. Prospective randomised trials in people with cancer and non-cancer are needed to determine whether oxygen can reduce the progression of breathlessness compared to a control arm.

Researching breathlessness in palliative care: consensus statement of the National Cancer Research Institute Palliative Care Breathlessness Subgroup

Breathlessness is common in advanced disease and can have a devastating impact on patients and carers. Research on the management of breathlessness is challenging. There are relatively few studies, and many studies are limited by inadequate power or design. This paper represents a consensus statement of the National Cancer Research Institute Palliative Care Breathlessness Subgroup. The aims of this paper are to facilitate the design of adequately powered multi-centre interventional studies in breathlessness, to suggest a standardised, rational approach to breathlessness research and to aid future 'between study' comparisons. Discussion of the physiology of breathlessness is included.

Dyspnea experience and management strategies in patients with lung cancer

OBJECTIVE

The aim of this paper was to describe lung cancer patients' experience of dyspnea and their strategies for managing the dyspnea.

METHODS

Semi-structured interviews with two main questions about dyspnea experiences and management were conducted with 20 patients with lung cancer, not amenable to curative treatment, who had completed life prolonging treatments. Data analysis was made with a descriptive, qualitative content analysis.

RESULTS

The two questions resulted in two domains with 7 categories and subcategories. The experience of dyspnea included four categories: 'Triggering factors' included circumstances contributing to dyspnea, which comprised physical, psychosocial and environmental triggers. Bodily manifestations were considered to be the core of the experience. 'Immediate reactions' concerned physical and psychological impact. The long-term reactions included limitations, increased dependence and existential impact concerning hope, hopelessness and thoughts of death. The experience of managing dyspnea included three categories: 'Bodily strategies', 'psychological strategies' and 'medical strategies'.

CONCLUSION

Dyspnea experience is a complex experience which influences the life of the patients both with immediate reactions and long-term reactions concerning physical, emotional and existential issues in life and patients address this experience with managing strategies in order to take control of their situation, although they do not seem to be able to meet the existential distress they experience.

Non-pharmacological interventions for breathlessness management in patients with lung cancer: a systematic review

The aim is to review the published scientific literature for studies evaluating non-pharmacological interventions for breathlessness management in patients with lung cancer. The following selection criteria were used to systematically search the literature: studies were to be published research or systematic reviews; they were to be published in English and from 1990 to 2007; the targeted populations were adult patients with dyspnoea/breathlessness associated with lung cancer; and the study reported on the outcomes from use of non-pharmacological strategies for breathlessness. This review retrieved five studies that met all inclusion criteria. All the studies reported the benefits of non-pharmacological interventions in improving breathlessness regardless of differences in clinical contexts, components of programmes and methods for delivery. Analysis of the available evidence suggests that tailored instructions delivered by nurses with sufficient training and supervision may have some benefits over other delivery approaches. Based on the results, non-pharmacological interventions are recommended as effective adjunctive strategies in managing breathlessness for patients with lung cancer. In order to refine such interventions, future research should seek to explore the core components of such approaches that are critical to achieving optimal outcomes, the contexts in which the interventions are most effective, and to evaluate the relative benefits of different methods for delivering such interventions.

Non-pharmacological interventions for breathlessness in advanced stages of malignant and non-malignant diseases

BACKGROUND

Breathlessness is a common and distressing symptom in the advanced stages of malignant and non-malignant diseases. Appropriate management requires both pharmacological and non-pharmacological interventions.

OBJECTIVES

The primary objective was to determine the effectiveness of non-pharmacological and non-invasive interventions to relieve breathlessness in participants suffering from the five most common conditions causing breathlessness in advanced disease.

SEARCH STRATEGY

We searched the following databases: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, British Nursing Index, PsycINFO, Science Citation Index Expanded, AMED, The Cochrane Pain, Palliative and Supportive Care Trials Register, The Cochrane Database of Systematic Reviews, and Database of Abstracts of Reviews of Effectiveness in June 2007. We also searched various websites and reference lists of relevant articles and textbooks.

SELECTION CRITERIA

We included randomised controlled and controlled clinical trials assessing the effects of non-pharmacological and non-invasive interventions to relieve breathlessness in participants described as suffering from breathlessness due to advanced stages of cancer, chronic obstructive pulmonary disease (COPD), interstitial lung disease, chronic heart failure or motor neurone disease.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed relevant studies for inclusion. Data extraction and quality assessment was performed by three review authors and checked by two other review authors. Meta-analysis was not attempted due to heterogeneity of studies.

MAIN RESULTS

Forty-seven studies were included (2532 participants) and categorised as follows: single component interventions with subcategories of walking aids (n = 7), distractive auditory stimuli (music) (n = 6), chest wall vibration (CWV, n = 5), acupuncture/acupressure (n = 5), relaxation (n = 4), neuro-electrical muscle stimulation (NMES, n = 3) and fan (n = 2). Multi-component interventions were categorised in to counselling and support (n = 5), breathing training (n = 3), counselling and support with breathing-relaxation training (n = 2), case management (n = 2) and psychotherapy (n = 2). There was a high strength of evidence that NMES and CWV could relieve breathlessness and moderate strength for the use of walking aids and breathing training. There is a low strength of evidence that acupuncture/acupressure is helpful. There is not enough data to judge the evidence for distractive auditory stimuli (music), relaxation, fan, counselling and support, counselling and support with breathing-relaxation training, case management and psychotherapy. Most studies have been conducted in COPD patients, only a few studies included participants with other conditions.

AUTHORS' CONCLUSIONS

Breathing training, walking aids, NMES and CWV appear to be effective non-pharmacological interventions for relieving breathlessness in advanced stages of disease.

The etiology and management of intractable breathlessness in patients with advanced cancer: a systematic review of pharmacological therapy

Intractable breathlessness is a common, devastating symptom of advanced cancer causing distress and isolation for patients and families. In advanced cancer, breathlessness is complex and usually multifactorial and its severity unrelated to measurable pulmonary function or disease status. Therapeutic advances in the clinical management of dyspnea are limited and it remains difficult to treat successfully. There is growing interest in the palliation of breathlessness, and recent work has shown that a systematic, evidence-based approach by a committed multidisciplinary team can improve lives considerably. Where such care is lacking it may be owing to therapeutic nihilism in clinicians untrained in the management of chronic breathlessness and unaware that there are options other than endurance. Optimum management involves pharmacological treatment (principally opioids, occasionally oxygen and anxiolytics) and nonpharmacological interventions (including use of a fan, a tailor-made exercise program, and psychoeducational support for patient and family) with the use of parenteral opioids and sedation at the end of life when appropriate. Effective care centers on the patient's needs and goals. Priorities in breathlessness research include studies on: neuroimaging, the effectiveness of new interventions, the efficacy, safety, and dosing regimens of opioids, the contribution of deconditioning, and the effect of preventing or reversing breathlessness.

Palliative care in lung cancer: ACCP evidence-based clinical practice guidelines (2nd edition)

GOALS/OBJECTIVES: To review the scientific evidence on symptoms and specific complications that are associated with lung cancer, and the methods available to palliate those symptoms and complications.

METHODS

MEDLINE literature review (through March 2006) for all studies published in the English language, including case series and case reports, since 1966 using the following medical subject heading terms: bone metastases; brain metastases; cough; dyspnea; electrocautery; hemoptysis; interventional bronchoscopy; laser; pain management; pleural effusions; spinal cord metastases; superior vena cava syndrome; and tracheoesophageal fistula.

RESULTS

Pulmonary symptoms that may require palliation in patients who have lung cancer include those caused by the primary cancer itself (dyspnea, wheezing, cough, hemoptysis, chest pain), or locoregional metastases within the thorax (superior vena cava syndrome, tracheoesophageal fistula, pleural effusions, ribs, and pleura). Respiratory symptoms can also result from complications of lung cancer treatment or from comorbid conditions. Constitutional symptoms are common and require attention and care. Symptoms referable to distant extrathoracic metastases to bone, brain, spinal cord, and liver pose additional problems that require a specific response for optimal symptom control. There are excellent scientific data regarding the management of many of these issues, with lesser evidence from case series or expert opinion on other aspects of providing palliative care for lung cancer patients.

CONCLUSIONS

Palliation of symptoms and complications in lung cancer patients is possible, and physicians who provide such care must be knowledgeable about these issues.

The impact of symptoms, coping capacity, and social support on quality of life experience over time in patients with lung cancer

The aims of the study were to investigate lung cancer patients' quality of life (QoL) over time in a palliative setting and to determine how QoL is influenced by symptoms, coping capacity, and social support. One hundred and five consecutive patients with incurable lung cancer were included. A comprehensive set of questionnaires was used at baseline, including the Assessment of Quality of Life at the End of Life, Cancer Dyspnea Scale, Visual Analog Scale of Dyspnea, Hospital Anxiety and Depression scale, Sense of Coherence Questionnaire, and Social Support Survey, of which the first four were used also at three, six, nine, and 12 months. Dyspnea, depression, and global QoL deteriorated over time. Performance status, anxiety, depression, components of dyspnea, pain, and the meaningfulness component of coping capacity correlated with global QoL at all, or all but one follow-up measurements. In a multivariate analysis with global QoL as the dependent variable, depression was a significant predictor at four out of five assessments, whereas coping capacity, anxiety, performance status, pain, and social support entered the model at one or two assessments. Emotional distress and coping capacity influence QoL and might be targets for intervention in palliative care.

Assessment and management of fatigue and dyspnea in pediatric palliative care

Fatigue is one of the most prevalent symptoms in patients with a life-threatening illness. Untreated, fatigue can impair quality of life and prohibit addressing practical needs, psychosocial and spiritual distress, and opportunities for growth and closure at life's end. To this end addressing fatigue is a crucial component of the provision of effective palliative care. Dyspnea is the sensation of breathlessness. The challenge in treating it, however, is that it can come from various different abnormalities so understanding the underlying disorder and the acute abnormality are critical. With that understanding several different treatments can be offered to treat the cause of the dyspnea or palliate the symptom itself.

Clinical Dilemma: Dyspnea

OBJECTIVES

To review the current state of evidence for the nursing treatment of cancer-related dyspnea.

DATA SOURCES

Nursing and medical literature, published guidelines, and Cochrane Systematic reviews.

CONCLUSION

Limited evidence exists for the current strategies used to treat dyspnea among persons with cancer.

IMPLICATIONS FOR NURSING PRACTICE

Nurses must be cognizant of the level of evidence or the lack of scientific evidence supporting treatment strategies used. Keeping abreast of the developments in the area of dyspnea management is imperative as research adds to the current body of evidence. Nurses are uniquely positioned to add to the body of evidence through collaboration with nurse researchers.

Death, dying, and last wishes

Issues regarding patient care near the end of life can be challenging and rewarding for emergency physicians. Knowledge of the patient's wishes is essential, and may be accomplished by advance directives or communication with patients and surrogates. Resuscitative efforts are appropriate for many patients, but inappropriate for others. The goals of medicine remain the following: providing optimal health care, provision of the best possible symptom control, communication, empathy, and caring. As death approaches, provision of the best possible medical care, in accordance with the patient's wishes, can be rewarding for patients, families, and health care providers.

The impact of a breathlessness intervention service (BIS) on the lives of patients with intractable dyspnea: A qualitative phase 1 study

Objective:Disabling breathlessness is the most common symptom of advanced cardiopulmonary disease. It is usually intractable, even when patients receive maximal medical therapy for their underlying condition. A pilot study was undertaken to evaluate a newly formed palliative Breathlessness Intervention Service (BIS).

Methods:The methodology followed the Medical Research Council's Framework for the Evaluation of Complex Interventions (Phase I). Qualitative interviews were completed with patients and relatives who had used the service and clinicians who had referred to it. The focus of the interviews was the participants' experience of using BIS.

Results:Patients valued the positive educational approach taken to breathlessness, emphasizing what was possible rather than what had been lost. Non-pharmacological strategies, especially the hand-held fan and exercises, were rated very helpful and new to patients. Participants reiterated that breathlessness was frightening and isolating, exacerbating the disability it caused: the easy access to advice and flexibility of BIS helped to alleviate this. Participants wanted a written record of the advice given. Carers welcomed the focus on their needs. Clinicians valued sharing the management of patients with an intractable problem.

Significance of results:This Phase I study has helped to remodel the service rapidly by uncovering the aspects of BIS that users find most valuable and areas that need change or improvement. The BIS needs to provide written information, to reinforce and extend contacts with other agencies to build on support it already provides for patients and carers, and extend its flexibility and accessibility. Providing a “drop-in” service and continuing education after the initial program of contacts is completed could be a useful service development, warranting further evaluation. A qualitative methodology involving service users and referrers can help to shape service development rapidly.
