Abstract
BACKGROUND Advanced heart failure patients suffer with breathlessness and peripheral oedema, which are frequently treated with parenteral diuretics despite limited evidence. AIM To analyse the effectiveness of parenteral diuretics on breathlessness and peripheral oedema in advanced heart failure patients. METHODS We searched Embase, MEDLINE(R), PsycINFO, CINAHL and CENTRAL from their respective inceptions to 2021, and performed handsearching, citation searching and grey literature search; limited to English publications. Selection criteria included parenteral (intravenous/subcutaneous) diuretic administration in advanced heart failure patients (New York Heart Association class III-IV). Two authors independently assessed articles for inclusion; one author extracted data. Data were synthesised through narrative synthesis or meta-analysed as appropriate. RESULTS 4646 records were screened; 6 trials (384 participants) were included. All were randomised controlled trials (RCTs) comparing intravenous continuous furosemide infusion (CFI) versus intravenous bolus furosemide infusion (BFI). Improvement in breathlessness and peripheral oedema (two studies, n=161, OR 2.80, 95% CI 1.45 to 5.40; I2=0%), and increase in urine output (four studies, n=234, mean difference, MD 344.76, 95% CI 132.87 to 556.64; I2=44%), were statistically significant in favour of CFI. Significantly lower serum potassium was found in BFI compared with CFI (three studies, n=194, MD -0.20, 95% CI -0.38 to -0.01; I2=0%). There was no difference between CFI and BFI on reduction in weight, renal function or length of hospital stay. CONCLUSIONS CFI appears to improve congestion in advanced heart failure patients in the short term. Available data came from small trials. Larger, prospective RCTs are recommended to address the evidence gap.

Abstract
BACKGROUND Dyspnea is a common and debilitating symptom that affects many different patient populations. Dyspnea measures should assess multiple domains. OBJECTIVE To evaluate the reliability, validity, and responsiveness of an ultra-brief, multi-dimensional dyspnea measure. DESIGN We adapted the DEG from the PEG, a valid 3-item pain measure, to assess average dyspnea intensity (D), interference with enjoyment of life (E), and dyspnea burden with general activity (G). PARTICIPANTS We used data from a multi-site randomized clinical trial among outpatients with heart failure. MAIN MEASURES We evaluated reliability (Cronbach's alpha), concurrent validity with the Memorial-Symptom-Assessment-Scale (MSAS) shortness-of-breath distress-orbothersome item and 7-item Generalized-Anxiety-Disorder (GAD-7) scale, knowngroups validity with New-York-Heart-Association-Functional-Classification (NYHA) 1-2 or 3-4 and presence or absence of comorbid chronic obstructive pulmonary disease (COPD), responsiveness with the MSAS item as an anchor, and calculated a minimal clinically important difference (MCID) using distribution methods. KEY RESULTS Among 312 participants, the DEG was reliable (Cronbach's alpha 0.92). The mean (standard deviation) DEG score was 5.26 (2.36) (range 0-10) points. DEG scores correlated strongly with the MSAS shortness of breath distress-or-bothersome item (r=0.66) and moderately with GAD-7 categories (ρ=0.36). DEG scores were statistically significantly lower among patients with NYHA 1-2 compared to 3-4 [mean difference (standard error): 1.22 (0.27) points, p<0.01], and those without compared to with comorbid COPD [0.87 (0.27) points, p<0.01]. The DEG was highly sensitive to change, with MCID of 0.59-1.34 points, or 11-25% change. CONCLUSIONS The novel, ultra-brief DEG measure is reliable, valid, and highly responsive. Future studies should evaluate the DEG's sensitivity to interventions, use anchor-based methods to triangulate MCID estimates, and determine its prognostic usefulness among patients with chronic cardiopulmonary and other diseases.

Abstract
BACKGROUND Reducing congestion remains a primary target of therapy for acutely decompensated heart failure. The VENUS-HF EFS (VENUS-Heart Failure Early Feasibility Study) is the first clinical trial testing intermittent occlusion of the superior vena cava with the preCARDIA system, a catheter mounted balloon and pump console, to improve decongestion in acutely decompensated heart failure. METHODS In a multicenter, prospective, single-arm exploratory safety and feasibility trial, 30 patients with acutely decompensated heart failure were assigned to preCARDIA therapy for 12 or 24 hours. The primary safety outcome was a composite of major adverse cardiovascular and cerebrovascular events through 30 days. Secondary end points included technical success defined as successful preCARDIA placement, treatment, and removal and reduction in right atrial and pulmonary capillary wedge pressure. Other efficacy measures included urine output and patient-reported symptoms. RESULTS Thirty patients were enrolled and assigned to receive the preCARDIA system. Freedom from device- or procedure-related major adverse events was observed in 100% (n=30/30) of patients. The system was successfully placed, activated and removed after 12 (n=6) or 24 hours (n=23) in 97% (n=29/30) of patients. Compared with baseline values, right atrial pressure decreased by 34% (17±4 versus 11±5 mm Hg, P<0.001) and pulmonary capillary wedge pressure decreased by 27% (31±8 versus 22±9 mm Hg, P<0.001). Compared with pretreatment values, urine output and net fluid balance increased by 130% and 156%, respectively, with up to 24 hours of treatment (P<0.01). CONCLUSIONS We report the first-in-human experience of intermittent superior vena cava occlusion using the preCARDIA system to reduce congestion in acutely decompensated heart failure. PreCARDIA treatment for up to 24 hours was well tolerated without device- or procedure-related serious or major adverse events and associated with reduced filling pressures and increased urine output. These results support future studies characterizing the clinical utility of the preCARDIA system. REGISTRATION URL: https://www.clinicaltrials.gov; Unique identifier: NCT03836079.

Abstract
La dificultad respiratoria, también conocida como disnea, es un síntoma frecuente que causa debilidad. Varios reportes han destacado la ausencia de disnea en un subgrupo de pacientes que padecen COVID-19, en la llamada hipoxemia «silenciosa» o «feliz». Los reportes también han mencionado la falta de una relación clara entre la gravedad clínica de la enfermedad y los niveles de disnea referidos por los pacientes. Se ha demostrado en gran medida que entre las complicaciones cerebrales del COVID-19 hay alta prevalencia de encefalopatía aguda, que podría afectar el procesamiento de las señales aferentes o bien la modulación descendente de las señales de disnea. En esta revisión pretendemos destacar los mecanismos implicados en la disnea y resumir la fisiopatología del COVID-19 y sus efectos en la interacción cerebro-pulmón. Posteriormente, presentamos hipótesis sobre la alteración de la percepción de la disnea en pacientes con COVID-19 y sugerimos formas de investigar más a fondo este fenómeno.

Abstract
CONTEXT In order to examine the multi-dimensional nature of dyspnea and its impact on the activities of daily living (ADLs) in patients with cardio-respiratory and cancer diseases, validated measures are needed. OBJECTIVES Our aim was to identify all the multi-dimensional clinical scales assessing dyspnea and its impact on ADLs in patients with cardio-respiratory and cancer diseases, and to critically appraise their psychometric properties. METHODS Five databases were systematically searched up to July 2020. Eligible criteria were: the examination of at least one psychometric property, and the recruitment of adults with a cardio-respiratory or cancer disease in non-emergency settings. The characteristics and psychometric properties of the studies included were presented through a narrative synthesis. The methodological quality of the studies and evidence synthesis were rated using the "COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)" criteria. RESULTS Forty-three studies, for which eight assessment scales had been identified, were included in the review. At the time of the review, three multi-dimensional assessment scales were available for assessing dyspnea symptoms, and five multi-dimensional scales were available to examine the impact of dyspnea on ADLs. Although the use of these scales has rapidly grown, evidence of psychometric properties has been reported as limited in most of the scales. CONCLUSION Despite the potential of the identified scales, further studies are needed to strength evidence on the validity and reliability of the multi-dimensional dyspnea scales. Furthermore, more studies appraising the content validity and responsiveness of the scales are specifically recommended.

Abstract
Atemnot, auch als Dyspnoe bezeichnet, ist ein häufiges und lähmendes Symptom. In mehreren Berichten wurde die Abwesenheit von Atemnot bei einer Untergruppe von Patienten mit COVID-19 hervorgehoben, die manchmal als «stille» oder «glückliche Hypoxie» bezeichnet wird. Ebenfalls wurde in Berichten erwähnt, dass es an einem klaren Zusammenhang zwischen dem klinischen Schweregrad der Erkrankung und der von den Patienten berichteten Schwere der Atemnot fehlt. Die zerebralen Komplikationen von COVID-19 sind weitgehend nachgewiesen, mit einer hohen Prävalenz akuter Enzephalopathien, die möglicherweise die Verarbeitung afferenter Signale oder die absteigende Modulation von Atemnotsignalen beeinträchtigen könnte. In dieser Übersichtsarbeit möchten wir die an der Atemnot beteiligten Mechanismen hervorheben und die Pathophysiologie von COVID-19 und den bekannten Auswirkungen der Erkrankung auf die Interaktion von Gehirn und Lunge zusammenfassen. Anschließend stellen wir Hypothesen für die Veränderung der Wahrnehmung von Atemnot bei COVID-19-Patienten auf und schlagen Möglichkeiten vor, mit denen dieses Phänomen weiter erforscht werden könnte.

Abstract
Background: Dyspnea is the most common presenting symptom among patients hospitalized for acute heart failure (AHF). Dyspnea relief constitutes a clinically relevant therapeutic target and endpoint for clinical trials and regulatory approval. However, there have been no widely accepted dyspnea measurement standards in AHF. By systematic review and mapping the current evidence of the applied scales, timing, and results of measurement, we hope to provide some new insights and recommendations for dyspnea measurement. Methods: PubMed, Embase, Cochrane Library, and Web of Science were searched from inception until August 27, 2020. Randomized controlled trials (RCTs) with dyspnea severity measured as the endpoint in patients with AHF were included. Results: Out of a total of 63 studies, 28 had dyspnea as the primary endpoint. The Likert scale (34, 54%) and visual analog scale (VAS) (22, 35%) were most widely used for dyspnea assessment. Among the 43 studies with detailed results, dyspnea was assessed most frequently on days 1, 2, 3, and 6 h after randomization or drug administration. Compared with control groups, better dyspnea relief was observed in the experimental groups in 21 studies. Only four studies that assessed tolvaptan compared with control on the proportion of dyspnea improvement met the criteria for meta-analyses, which did not indicate beneficial effect of dyspnea improvement on day 1 (RR: 1.16; 95% CI: 0.99-1.37; p = 0.07; I 2 = 61%). Conclusion: The applied scales, analytical approaches, and timing of measurement are in diversity, which has impeded the comprehensive evaluation of clinical efficacy of potential therapies managing dyspnea in patients with AHF. Developing a more general measurement tool established on the unified unidimensional scales, standardized operation protocol to record the continuation, and clinically significant difference of dyspnea variation may be a promising approach. In addition, to evaluate the effect of experimental therapies on dyspnea more precisely, the screening time and blinded assessment are factors that need to be considered.

Abstract
Breathlessness, also known as dyspnoea, is a debilitating and frequent symptom. Several reports have highlighted the lack of dyspnoea in a subgroup of patients suffering from COVID-19, sometimes referred to as “silent” or “happy hypoxaemia.” Reports have also mentioned the absence of a clear relationship between the clinical severity of the disease and levels of breathlessness reported by patients. The cerebral complications of COVID-19 have been largely demonstrated with a high prevalence of an acute encephalopathy that could possibly affect the processing of afferent signals or top-down modulation of breathlessness signals. In this review, we aim to highlight the mechanisms involved in breathlessness and summarize the pathophysiology of COVID-19 and its known effects on the brain-lung interaction. We then offer hypotheses for the alteration of breathlessness perception in COVID-19 patients and suggest ways of further researching this phenomenon.

Acceptability and accuracy of patient-reported outcome measures (PROMs) for surveillance of breathlessness in routine lung cancer care: A mixed-method study. Lung Cancer 2020; 147:1-11. [PMID: 32634651 DOI: 10.1016/j.lungcan.2020.06.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/17/2020] [Accepted: 06/23/2020] [Indexed: 01/17/2023]
Abstract
BACKGROUND Breathlessness in lung cancer negatively impacts on quality of life but often goes undetected and undertreated in clinical practice. There is a need for routine surveillance for early identification and proactive management of breathlessness using patient reported outcome measures (PROMs) in clinical care but it is unclear what PROMs should be used or are accurate for use in routine care. METHODS We used mixed-methods (quantitative surveys and qualitative interviews) to examine the predictors of breathlessness in 339 lung cancer participants and acceptability of PROMs. In addition to multivariate analysis to examine predictors of dyspnea, participants completed an acceptability survey and themes were derived for the qualitative data (n = 26) to explore patient experience of PROMs. We also tested the accuracy of PROMs using a Receiver Operating Characteristic and Area Under the Curve analysis. RESULTS A total of 339 patients completed the breathlessness PROMs and acceptability survey and 26 patients participated in an in-depth interview to investigate their experiences of breathlessness and its PROMs. Prevalence of breathlessness was 51.9 % (n = 176) and 70.5 % of patients preferred the Medical Research Council (MRC) scale followed by the Breathlessness Intensity (BI) scale (63.7 %) among the five measures for breathlessness- Modified Borg Scale (MBS), Cancer Dyspnea Scale (CDS), MRC, BI, and Breathlessness Distress (BD). The finding showed wide variation in the MRC grades across the BI rating even among patients with the same BI score. AUC scores for the Borg scale was 0.71 (using MRC cut-off score of < 2), for CDS, 0.72, for BD, 0.70, and for BI 0.79. For an MRC score of 2, the Borg score cut-off was 0.8 (optimal sensitivity, 50 %; specificity, 93.3 %); the cut-off score of CDS, BD, BI score was 1.4 (optimal sensitivity, 67.1 %; specificity, 70 %), 1.5 (optimal sensitivity, 57.5 %; specificity, 73.3 %), and 1.5 (optimal sensitivity, 72.6 %; specificity, 83.3 %) respectively. AUC by ROC analysis for breathlessness and modest concordance among five PROMs showed important gaps between the individuals' experience and PROMs data. Three main themes from qualitative data included 1) Making sense of symptom reporting, 2) Valuing the reported data, 3) Managing the symptom of breathlessness. CONCLUSION This study examined measurement of breathlessness using PROMs for routine clinical care and showed that severity measures alone do not accurately detect this symptomnor the experiential dimensions of breathlessness that are critical to guide appropriate intervention.

Abstract
PURPOSE OF REVIEW The experience of breathlessness in patients with heart failure is understudied. This review was aimed at evaluating the most recent qualitative findings regarding the experience of breathlessness in persons diagnosed with heart failure. RECENT FINDINGS A literature search was conducted using Pubmed, Psycinfo, BNI, Cinahl and Google Scholar including studies on breathlessness experience in patients with heart failure, published between 2017 and 2018. Only three studies were identified, and findings were categorized into five themes: acknowledgment of breathlessness, prevailing consequences of breathlessness, breathlessness in daily life, recognising when breathlessness is a problem and communicating breathlessness. Understanding the experience of breathlessness was different before and after heart failure diagnosis. Patients experienced similar physical and emotional consequences of breathlessness but varied in strategies to manage the symptom. Patients often do not report breathlessness symptom, or are not asked to describe their symptom by the provider. SUMMARY Recent studies show those at risk for and those who have heart failure need appropriate education to recognize breathlessness as a critical symptom. In addition, adequate communication between patients and providers of the breathlessness symptom is needed to support management.

Findings From a Mixed-Methods Double-Blind Randomized Feasibility Trial. J Pain Symptom Manage 2019; 58:369-381.e7. [PMID: 31201877 DOI: 10.1016/j.jpainsymman.2019.06.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 06/04/2019] [Accepted: 06/05/2019] [Indexed: 11/30/2022]
Abstract
CONTEXT Chronic or refractory breathlessness is common and distressing. To evaluate new treatments, outcome measures that capture change in patients' experience are needed. OBJECTIVES To explore the extent to which the numerical rating scale (NRS) worst and average, and the Chronic Respiratory Questionnaire capture change in patients' experience during a trial of mirtazapine for refractory breathlessness. METHODS Convergent mixed-methods design embedded within a randomized trial comprising 1) semi-structured qualitative interviews (considered to be the gold standard) and 2) outcome measure data collected pre- and post-intervention. Data were integrated, exploring examples where findings agreed and disagreed. Adults with advanced cancer, chronic obstructive pulmonary disease, interstitial lung disease, or chronic heart failure, with a modified Medical Research Council dyspnea scale grade 3 or 4 were recruited from three U.K. sites. RESULTS Data were collected for 22 participants. Eleven had a diagnosis of chronic obstructive pulmonary disease, eight interstitial lung disease, two chronic heart failure, and one cancer. Median age was 71 (56-84) years. Sixteen participants were men. Changes in the qualitative data were commonly captured in the NRS (worst and average) and the Chronic Respiratory Questionnaire. The NRS worst captured change most frequently. Improvement in the emotional domain was associated with physical changes, improved confidence, and control. CONCLUSION This study found that the NRS using the question "How bad has your breathlessness felt at its worst over the past 24 hours?" captured change across multiple domains, and therefore may be an appropriate primary outcome measure in trials in this population. Future work should confirm the construct validity of this question.

A Multidimensional Profile of Dyspnea in Hospitalized Patients. Chest 2019; 156:507-517. [PMID: 31128117 DOI: 10.1016/j.chest.2019.04.128] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 03/26/2019] [Accepted: 04/02/2019] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Dyspnea is prevalent among hospitalized patients but little is known about the experience of dyspnea among inpatients. We sought to characterize the multiple sensations and associated emotions of dyspnea in patients admitted with dyspnea to a tertiary care hospital. METHODS We selected patients who reported breathing discomfort of at least 4/10 on admission (10 = unbearable). Research staff recruited 156 patients within 24 hours of admission and evaluated daily patients' current and worst dyspnea with the Multidimensional Dyspnea Profile; patients participated in the study 2.6 days on average. The Multidimensional Dyspnea Profile assesses overall breathing discomfort (A1), intensity of five sensory qualities of dyspnea, and 5 negative emotional responses to dyspnea. Patients were also asked to rate whether current levels of dyspnea were "acceptable." RESULTS At the time of the first research interview, patients reported slight to moderate dyspnea (A1 median 4); however, most patients reported experiencing severe dyspnea in the 24 hours before the interview (A1 mean 7.8). A total of 54% of patients with dyspnea ≥4 on day 1 found the symptom unacceptable. The worst dyspnea each day in the prior 24 hours usually occurred at rest. Dyspnea declined but persisted through hospitalization for most patients. "Air hunger" was the dominant sensation, especially when dyspnea was strong (>4). Anxiety and frustration were the dominant emotions associated with dyspnea. CONCLUSIONS This first multidimensional portrait of dyspnea in a general inpatient population characterizes the sensations and emotions dyspneic patients endure. The finding that air hunger is the dominant sensation of severe dyspnea has implications for design of laboratory models of these sensations and may have implications for targets of palliation of symptoms.

Abstract
Aims Dyspnoea is common in heart failure (HF) but non‐specific. Lung ultrasound (LUS) could represent a non‐invasive tool to detect subclinical pulmonary congestion in patients with undifferentiated dyspnoea. Methods and results We assessed the feasibility of an abbreviated LUS protocol (eight and two zones) in a prospective pilot study of 25 ambulatory patients with undifferentiated dyspnoea undergoing clinically indicated invasive cardiopulmonary exercise testing (iCPET) at rest (LUS 1) and after peak exercise (LUS 2). We also related LUS findings (B‐lines) to invasive haemodynamics stratified by supine pulmonary capillary wedge pressure (PCWP) (Congestion, >15 mmHg; Control, ≤15 mmHg). All enrolled patients (median age 68, 60% women, 32% prior HF, median ejection fraction 59%) had interpretable LUS 1 images in eight zones, and 20 (80%) had adequate LUS 2 images. LUS images were adequate in two posterior zones in 24 patients (96%) for LUS 1 and 18 (72%) for LUS 2. Although B‐line number was numerically higher in the Congestion group at rest and after peak exercise, this difference did not reach statistical significance. In the entire cohort, there was an association between B‐lines and rest systolic pulmonary artery pressure (r = 0.46, P = 0.02) and PCWP (r = 0.54, P = 0.005). There was an inverse relationship between B‐lines and peak VO2 (r = −0.65, P = 0.002). Conclusions Among ambulatory patients with undifferentiated dyspnoea, an abbreviated LUS protocol before and after iCPET is feasible in the majority of patients. B‐line number at rest was associated with invasively measured markers of haemodynamic congestion and was inversely related with peak VO2.

Abstract
Breathlessness or dyspnoea is a subjective experience that can be described as an unpleasant or uncomfortable awareness of breathing. It is a subjective experience for patients and often they learn to adapt to the limitations caused by their condition, which makes their breathlessness less apparent to others. Breathlessness can be subdivided in the context of chronic refractory breathlessness, such as acute breathlessness, which is either an episodic breathlessness or breathlessness crisis. Chronic refractory breathlessness is defined as breathlessness at rest or on minimal exertion that will persist chronically despite optimal treatment of the underlying causative factors. The role of the community nurse in managing the breathless patient should involve differentiating between different types of breathlessness and knowing how to effectively manage it in a holistic manner.

Abstract
Background Dyspnoea is a disabling symptom in patients admitted with heart failure (HF) and respiratory diseases (RD). The main aim of this study is to evaluate its intensity at admission and discharge and the relation with quality of life. We also describe its management, intensity, and evolution in HF and RD. Methods In this descriptive, cross-sectional study, we included prospectively all patients admitted with decompensated HF and chronic obstructive pulmonary disease (COPD)/pulmonary fibrosis during 4 months. Surveys quantifying dyspnoea (Numerical Rating Scale 1-10) and quality of life (EuroQoL 5d) were administered at discharge. Results A total of 258 patients were included: 190 (73.6%) with HF and 68 (26.4%) with RD (62 COPD and 6 pulmonary fibrosis). Mean age was 74.0±1.2 years, and 157 (60.6%) were men. Dyspnoea before admission was 7.5±0.1. Patients with RD showed greater dyspnoea than those with HF both before admission (8.1±0.2 vs. 7.3±0.2, p=0.01) and at discharge (3.2±0.3 vs. 2.0±0.2, p=0.0001). They also presented a higher rate of severe dyspnoea (≥5) at discharge (23 [34.3%] vs. 36 [19.1%], p=0.02). Opioids were used in 41 (15.9%), mean dose 8.7±0.8 mg Morphine Equivalent Daily Dose. HF patients had worse EuroQoL 5d scores than those with RD, due to mobility problems (118 [62.1%] vs. 28 [41.8%], p=0.004), and lower punctuation in Visual Analogue Scale (57.9±1.6 vs. 65.6±1.0, p=0.006). Conclusions About a quarter of patients admitted with HF or RD persist with severe dyspnoea at discharge. Opioids are probably underused. HF patients have less dyspnoea than patients with RD but present worse quality of life.

Abstract
PURPOSE OF REVIEW The review provides an overview of recent understanding in relation to the mechanisms relating to skeletal muscle and the sympathetic nervous system, and therapies for breathlessness which target these mechanisms. These are set in the context of established knowledge in this field. RECENT FINDINGS Despite strong evidence to support exercise training programmes, and recommendations in international guidelines, programmes are implemented poorly. Electrical stimulation appears to be a way of exercising people too frail to undertake a full exercise programme. There is evidence to support the use of opioids for breathlessness in other conditions, but as yet the evidence in chronic heart failure is mixed. SUMMARY Previous work in relation to the role of skeletal muscle and sympathetic nervous system has set the scene for targeted therapies for the relief of breathlessness in people with heart failure.

Abstract
The purpose of this review is to provide a guide for researchers and clinicians in selecting an instrument to measure four commonly occurring symptoms (dyspnea, chest pain, palpitations, and fatigue) in cardiac populations (acute coronary syndrome, heart failure, arrhythmia/atrial fibrillation, and angina, or patients undergoing cardiac interventions). An integrative review of the literature was conducted. A total of 102 studies summarizing information on 36 different instruments are reported in this integrative review. The majority of the instruments measured multiple symptoms and were used for one population. A majority of the symptom measures were disease-specific and were multi-dimensional. This review summarizes the psychometrics and defining characteristics of instruments to measure the four commonly occurring symptoms in cardiac populations. Simple, psychometrically strong instruments do exist and should be considered for use; however, there is less evidence of responsiveness to change over time for the majority of instruments.

Abstract
Older people often suffer from multiple diseases. Therefore, universal cross-disease outcomes (e.g. functional status, quality of life, overall survival) are more relevant than disease-specific outcomes, and a range of potential outcomes are needed for medical decision-making. To assess how patient-relevant outcomes have penetrated randomized controlled trials (RCTs), reporting of these outcomes was reviewed in heart failure trials that included patients with multimorbidity. We systematically reviewed RCTs (Jan 2011–June 2012) and evaluated reported outcomes. Heart failure was chosen as condition of interest as this is common among older patients with multimorbidity. The main outcome was the proportion of RCTs reporting all-cause mortality, all-cause hospital admission, and outcomes in four domains of health, i.e. functional, signs and symptoms, psychological, and social domains. Of the 106 included RCTs, 50 (47 %) reported all-cause mortality and cardiovascular mortality and 29 (27 %) reported all-cause hospitalization and cardiovascular hospitalization. Of all trials, 68 (64 %) measured outcomes in the functional domain, 80 (75 %) in the domain of signs and symptoms, 65 (61 %) in the psychological domain, and 59 (56 %) in the social domain. Disease-specific instruments were more often used than non-disease-specific instruments. This review shows increasing attention for more patient-relevant outcomes; this is promising and indicates more awareness of the importance of a variety of outcomes desirable for patients. However, patients’ individual goal attainments were universally absent. For continued progress in patient-centred care, efforts are needed to develop these outcomes, study their merits and pitfalls, and intensify their use in research.

Abstract
This study presents a method for objectively measuring in-chair movement (ICM) that shows correlation with subjective ratings of comfort and discomfort. Employing a cross-over controlled, single blind design, healthy young subjects (n = 21) sat for 18 min on each of the following surfaces: contoured foam, straight foam and wood. Force sensitive resistors attached to the sitting interface measured the relative movements of the subjects during sitting. The purpose of this study was to determine whether ICM could statistically distinguish between each seat material, including two with subtle design differences. In addition, this study investigated methodological considerations, in particular appropriate threshold selection and sitting duration, when analysing objective movement data. ICM appears to be able to statistically distinguish between similar foam surfaces, as long as appropriate ICM thresholds and sufficient sitting durations are present. A relationship between greater ICM and increased discomfort, and lesser ICM and increased comfort was also found.

Abstract
Dyspnea limits physical activity and functional status in heart failure patients. This feasibility study examined effects of a diaphragmatic breathing retraining (DBR) intervention delivered over 8 weeks with follow-up at 5 months. The intervention group (n = 18) was trained at baseline and received four telephone calls. An attention control group (n = 18) received four telephone calls with general health information. Results from linear mixed model analysis with effect sizes (η(2)) showed dyspnea improved in both groups, with little difference between groups. Compared with attention alone, the intervention increased physical activity (calories expended; η(2) = .015) and functional status (η(2) = .013) across the 5-month follow-up and increased activity counts at 8 weeks (η(2) = .070). This intervention was feasible and demonstrated promising effects on activity and function but not by reducing dyspnea. Patients may have increased physical activity because of instructions to use DBR during activities of daily living. Further exploration of the intervention's underlying physiological effect is needed.

Abstract
OBJECTIVE(S) Dyspnoea is a common and often debilitating symptom that affects up to 50% of patients admitted to acute tertiary care hospitals. The primary purpose of this study was to compare the numeric rating scale (NRS) and the visual analogue scale (VAS) for dyspnoea evaluation in the ED setting. STUDY DESIGN AND PATIENTS This was a cohort study of patients admitted to the ED in a university hospital, with dyspnoea as the chief complaint. METHODS The agreement of the two dyspnoea scales was assessed using the intraclass correlation coefficient (ICC). RESULTS One hundred and seventeen patients were included in this analysis. The median age for the whole study population was 67 years and 42% of patients were male. The aetiology of dyspnoea was acute heart failure (AHF) in 35% of patients. There was good agreement between the two scores (ICC=0.795; 95% CI=0.717-0.853; P<0.001). CONCLUSIONS This pilot study demonstrated that numerical rating and visual analogue scales agree well when assessing the severity of dyspnoea in the ED. Further studies with larger cohorts of patients are needed to confirm these preliminary results.

Abstract
There is growing awareness that dyspnoea, like pain, is a multidimensional experience, but measurement instruments have not kept pace. The Multidimensional Dyspnea Profile (MDP) assesses overall breathing discomfort, sensory qualities, and emotional responses in laboratory and clinical settings. Here we provide the MDP, review published evidence regarding its measurement properties and discuss its use and interpretation. The MDP assesses dyspnoea during a specific time or a particular activity (focus period) and is designed to examine individual items that are theoretically aligned with separate mechanisms. In contrast, other multidimensional dyspnoea scales assess recalled recent dyspnoea over a period of days using aggregate scores. Previous psychophysical and psychometric studies using the MDP show that: 1) subjects exposed to different laboratory stimuli could discriminate between air hunger and work/effort sensation, and found air hunger more unpleasant; 2) the MDP immediate unpleasantness scale (A1) was convergent with common dyspnoea scales; 3) in emergency department patients, two domains were distinguished (immediate perception, emotional response); 4) test–retest reliability over hours was high; 5) the instrument responded to opioid treatment of experimental dyspnoea and to clinical improvement; 6) convergent validity with common instruments was good; and 7) items responded differently from one another as predicted for multiple dimensions. The Multidimensional Dyspnea Profile provides a unified, reliable instrument for both clinical and laboratory researchhttp://ow.ly/Ix8ic

Abstract
OBJECTIVES Although pericardial effusions (PE) and pleural effusions (PLE) may lead to life-threatening respiratory and circulatory deterioration following open heart surgery the postoperative frequency is not fully recognized. The diagnosis is typically based on ultrasonography, X-ray or computer tomography and often disclosed when circulatory collapse is evident. Point-of-care (POC) ultrasonography protocols constitute a noninvasive evaluation of the cardiopulmonary status. We hypothesized that POC ultrasonography could diagnose unknown PE and PLE. DESIGN Patients scheduled for open heart surgery were eligible for inclusion. Baseline evaluation including POC examination and dyspnea score was performed one day prior to surgery and repeated on the 4th and 30th postoperative day. RESULTS Eighty patients were included and complete follow-up was 80%. Thirteen patients (19%) had PE on the 4th day postsurgery and 19 patients (30%) had PE on the 30th day. Ultrasonography facilitated change in management in one patient with PE requiring drainage. Forty-nine patients (70%) had PLE on the 4th day following surgery and 19 patients (30%) had PLE on the 30th postoperative day. Ultrasonography facilitated a change in management in seven patients with PLE requiring drainage. CONCLUSION POC ultrasonography detected pathology, otherwise undisclosed, and was responsible for a change in management in a considerable number of cases.

Abstract
Abstract Background: Thirst is a bothersome symptom of chronic heart failure (CHF) which impacts adversely on quality of life. Despite this, limited work has been done to investigate thirst as a symptom or to develop reliable and valid measures of thirst in CHF. The purpose of this manuscript is to establish which tools have been used in research to measure thirst in CHF. Methods: Medline, PubMed, CINAHL, and Scopus were searched using following key words thirst, heart failure, measure, scale, randomised controlled trials and multicentre studies. Results: The search discovered 37 studies of which 6 studies met the inclusion criteria. One study was a research abstract and five were full- text studies. To date, there are only three measurement tools utilised in studies examining thirst in CHF patients (Visual Analogue Scale, Numeric Rating Scale and Thirst Distress Scale). Conclusion: Thirst in CHF is measured in a non- systematic way. In recent studies, the VAS has been used to measure thirst intensity. While this measurement tool is very easy and quick to administer, using a uni-dimensional tool in conjunction with a multi-dimensional tool may be beneficial to capture all dimensions of thirst. In order to manage thirst efficiently, consistent measurement of thirst in CHF is vital.

Abstract
Patient-reported outcomes (PROs), such as symptoms, health-related quality of life (HRQOL), or patient perceived health status, are reported directly by the patient and are powerful tools to inform patients, clinicians, and policy-makers about morbidity and 'patient suffering', especially in chronic diseases. Patient-reported outcomes provide information on the patient experience and can be the target of therapeutic intervention. Patient-reported outcomes can improve the quality of patient care by creating a holistic approach to clinical decision-making; however, PROs are not routinely used as key outcome measures in major cardiovascular clinical trials. Thus, limited information is available on the impact of cardiovascular therapeutics on PROs to guide patient-level clinical decision-making or policy-level decision-making. Cardiovascular clinical research should shift its focus to include PROs when evaluating the efficacy of therapeutic interventions, and PRO assessments should be scientifically rigorous. The European Society of Cardiology and other professional societies can take action to influence the uptake of PRO data in the research and clinical communities. This process of integrating PRO data into comprehensive efficacy evaluations will ultimately improve the quality of care for patients across the spectrum of cardiovascular disease.

Abstract
BACKGROUND Dyspnea is the most common symptom in acute heart failure (AHF), yet how to best measure it has not been well defined. Prior studies demonstrate differences in dyspnea improvement across various measurement scales, yet these studies typically enroll patients well after the emergency department (ED) phase of management. OBJECTIVES The aim of this study was to determine predictors of early dyspnea improvement for three different, commonly used dyspnea scales (i.e., five-point absolute Likert scale, 10-cm visual analog scale [VAS], or seven-point relative Likert scale). METHODS This was a post hoc analysis of URGENT Dyspnea, an observational study of 776 patients in 17 countries enrolled within 1 hour of first physician encounter. Inclusion criteria were broad to reflect real-world clinical practice. Prior literature informed the a priori definition of clinically significant dyspnea improvement. Resampling-based multivariable models were created to determine patient characteristics significantly associated with dyspnea improvement. RESULTS Of the 524 AHF patients, approximately 40% of patients did not report substantial dyspnea improvement within the first 6 hours. Baseline characteristics were similar between those who did or did not improve, although there were differences in history of heart failure, coronary artery disease, and initial systolic blood pressure. For those who did improve, patient characteristics differed across all three scales, with the exception of baseline dyspnea severity for the VAS and five-point Likert scale (c-index ranged from 0.708 to 0.831 for each scale). CONCLUSIONS Predictors of early dyspnea improvement differ from scale to scale, with the exception of baseline dyspnea. Attempts to use one scale to capture the entirety of the dyspnea symptom may be insufficient.

Abstract
Previous studies have suggested that patients with dyspnea referred for stress testing have high mortality. However, it is not clear whether this is explained by high rates of ischemia. The aim of the present study was to evaluate the incidence of ischemia in patients with dyspnea compared with patients with chest pain referred for stress testing and assess the outcomes of such patients. We systematically searched the electronic databases, MEDLINE, PubMed, EMBASE, and the Cochrane Library, until December 2012 to identify studies of patients with known or suspected coronary artery disease undergoing stress testing. We extracted data on group-specific incidence of stress-induced ischemia and all-cause mortality. In our analyses, we identified and included 6 studies that evaluated a total of 5,753 patients with dyspnea and 24,491 patients with chest pain as the clinical indication for stress testing. There was no statistically significant difference in the incidence of ischemia on stress imaging in patients with dyspnea compared with patients with chest pain (37.4% vs 30.2%, odds ratio 1.43, 95% confidence interval 0.99 to 2.06, p = 0.06). However, during the follow-up period, patients with dyspnea had higher all-cause mortality rates compared with patients with chest pain (annual mortality 4.9% vs 2.3%), with odds ratio of 2.57 (95% confidence interval 1.75 to 3.76, p <0.001). In conclusion, in patients undergoing stress testing, those evaluated for dyspnea had a significant increase in all-cause mortality but did not have higher rates of ischemia compared with patients presenting with chest pain. Clinicians evaluating patients with self-reported dyspnea should be aware that these patients represent a high-risk group with increased risk of mortality.

Abstract
CONTEXT Clinically important differences in chronic refractory breathlessness are ill defined but important in clinical practice and trial design. OBJECTIVES To estimate the clinical relevance of differences in breathlessness intensity using distribution and patient anchor methods. METHODS This was a retrospective data analysis from 213 datasets from four clinical trials for refractory breathlessness. Linear regression was used to explore the relationship between study effect size and change in breathlessness score (0-100mm visual analogue scale) and to estimate the change in score equivalent to small, moderate, and large effect sizes. Pooled individual blinded patient preference data from three randomized controlled trials were analyzed. The difference between the mean change in Day 4 minus baseline scores between preferred and non-preferred arms was calculated. RESULTS There was a strong relationship between change in score and effect size (P = 0.001; R(2) = 0.98). Values for small, moderate, and large effects were -5.5, -11.3, and -18.2mm. The participant preference change in score was -9mm (95% CI, -15.8, -2.1) (P = 0.008). CONCLUSION This larger dataset supports a clinically important difference of 10mm. Studies should be powered to detect this difference.

Abstract
BACKGROUND A pre-conference workshop at the 2012 European Association of Palliative Care meeting discussed the current scientific and clinical aspects of breathlessness. AIM To describe a current overview of clinically relevant science in breathlessness. DESIGN A collation of workshop presentations and discussions. DATA SOURCES Narrative review. RESULTS The mismatch between the drive to breathe and the ability to breathe underlies the major theories of breathlessness unifying central processing of peripheral inputs including more recent recognition of the importance of peripheral muscles in mediating efferent inputs, supporting reduction of breathlessness with muscle conditioning. Key questions are whether there is a 'final common pathway' for breathlessness? Are the central nervous system targets for reducing breathlessness identical irrespective of underlying aetiology? Central nervous system functional imaging confirms an ability to differentiate severity (intensity) from affective components (unpleasantness). Breathlessness generates suffering across the community for patients and their caregivers often for long periods. The exertional nature of breathlessness means that reduction rather than elimination of the symptom is the therapeutic goal. No single intervention is likely to relieve chronic refractory breathlessness, but interventions made up of several components may provide incremental relief. Having optimally treated any underlying reversible components, the resultant chronic refractory breathlessness can be treated with pharmacological, psychological and physical therapies to reduce the sensation and its impacts. CONCLUSION Ensuring optimal delivery of interventions for breathlessness, whose design is underpinned by improving the understanding in the aetiology and maintenance of breathlessness, is the subject of ongoing controlled clinical trials.

Abstract
AbstractObjective:Breathlessness is a subjective symptom, which makes it difficult to define and understand. The aim of the present study was to illuminate how patients suffering from breathlessness experience their everyday life.Method:The study was a qualitative study, and the focus of the analysis was the patients' descriptions of their experiences of breathlessness using a diary with two unstructured questions for a period of 7 consecutive days. Sixteen participants: 7 men, mean age 65 ± 7 (range 55–73 years old), and 9 women, mean age 65 ± 9 (range 50–72 years old) participated in the study.Results:Two themes emerged from the analysis: 1) Impaired quality of life and 2) symptom tolerance and adaptation. The theme “impaired quality of life” included the categories limited physical ability, psychological burdens, and social life barriers. The theme “symptom tolerance and adaptation” included importance of health care, social support, hobbies and leisure activities, and coping strategies.Significance of results:The findings in our study showed that patients, in spite of considerable difficulties with shortness of breath, found relief in several types of activities, in addition to drug therapy. The result indicates that the “biopsychosocial model” is an appealing approach that should be discussed further to gain a better understanding of breathlessness.

Abstract
Background—
Although the benefits of cardiac resynchronization therapy are well established in selected patients with heart failure and a prolonged QRS duration, salutary effects in patients with narrow QRS complexes remain to be demonstrated.
Methods and Results—
The Evaluation of Resynchronization Therapy for Heart Failure (LESSER-EARTH) trial is a randomized, double-blind, 12-center study that was designed to compare the effects of active and inactive cardiac resynchronization therapy in patients with severe left ventricular dysfunction and a QRS duration <120 milliseconds. The trial was interrupted prematurely by the Data Safety and Monitoring Board because of futility and safety concerns after 85 patients were randomized. Changes in exercise duration after 12 months were no different in patients with and without active cardiac resynchronization therapy (−0.7 minutes [95% confidence interval (CI), −2.9 to 1.5] versus 0.8 minutes [95% CI, −1.2 to 2.9];
P
=0.31]. Similarly, no significant differences were observed in left ventricular end-systolic volumes (−6.4 mL [95% CI, −18.8 to 5.9] versus 3.1 mL [95% CI, −9.2 to 15.5];
P
=0.28) and ejection fraction (3.3% [95% CI, 0.7–6.0] versus 2.1% [95% CI, −0.5 to 4.8];
P
=0.52). Moreover, cardiac resynchronization therapy was associated with a significant reduction in the 6-minute walk distance (−11.3 m [95% CI, −31.7 to 9.7] versus 25.3 m [95% CI, 6.1–44.5];
P
=0.01), an increase in QRS duration (40.2 milliseconds [95% CI, 34.2–46.2] versus 3.4 milliseconds [95% CI, 0.6–6.2];
P
<0.0001), and a nonsignificant trend toward an increase in heart failure–related hospitalizations (15 hospitalizations in 5 patients versus 4 hospitalizations in 4 patients).
Conclusions—
In patients with a left ventricular ejection fraction ≤35%, symptoms of heart failure, and a QRS duration <120 milliseconds, cardiac resynchronization therapy did not improve clinical outcomes or left ventricular remodeling and was associated with potential harm.

Abstract
AIMS Quantification of linear lung ultrasound (LUS) artefacts (B-lines) represents a novel, non-invasive approach to assess pulmonary congestion. We investigated the relationship between the number of B-lines (vertical artefacts arising from the pleural line) and intracardiac pressures. METHODS AND RESULTS Prior to scheduled right heart catheterization (RHC), 100 subjects underwent LUS of eight zones. A reviewer blinded to the haemodynamic data quantified the number of sonographic B-lines. Of 92 subjects who completed RHC, 79 had adequate LUS data of all zones [median age 61 years, 26 women, median left ventricular ejection fraction (LVEF) 58%, 35 with history of heart failure; 22 postcardiac transplantation]. The number of B-lines correlated with measured right atrial (r = 0.32), pulmonary artery diastolic (PADP) (r = 0.34), mean pulmonary artery (mPAP) (r = 0.43), pulmonary artery systolic (PASP) (r = 0.48) pressures, and pulmonary vascular resistance (PVR) (r = 0.51) (P < 0.005 for all), but not with pulmonary capillary wedge pressure. There was a graded association between tertiles of B-line number and increasing PADP, mPAP, PASP, and PVR (P for trend ≤0.001 for all). Each additional B-line was associated with an increase in PASP of 1 mmHg and an increase in PVR of 0.1 Wood units. These associations remained robust after multivariable adjustment (P = 0.002). Assessment of two inferior lateral zones resulted in similar correlations to the eight-zone method. CONCLUSIONS Easily obtainable, LUS may be useful in the estimation of right-sided cardiac pressures and PVR. Further evaluation of lung ultrasound as an adjunct to heart failure diagnosis, monitoring, and prognosis is warranted.

Abstract
OBJECTIVES The aim of the study was to determine the minimally clinically important difference (MCID) for breathlessness due to chronic heart failure (CHF). BACKGROUND The measurement of breathlessness is difficult because it is subjective and multifactorial. Statistically significant changes in assessment may not be clinically meaningful. This is the first determination of MCID in chronic breathlessness in CHF using patient-rated data. METHODS Measurements were made as part of a randomized, controlled, crossover trial of morphine, oxycodone, or placebo for breathlessness in CHF. Breathlessness intensity was assessed at baseline and at the end of each intervention (day 4) using 11-point numerical rating scales (NRS), modified Borg (mBorg) scales, and global impression of change (GC) in breathlessness at day 4. From these data, the change in NRS or mBorg associated with a 1-point change in GC was calculated. RESULTS Thirty-five patients completed all study interventions, resulting in 105 data sets. We defined MCID as a 1-point change in GC. Regression analysis found that the MCID, including 95% CIs, equaled change in average NRS breathlessness per 24 hours of 0.5 to 2.0 U (P < .001), change in worst NRS breathlessness per 24 hours of 0.4 to 2.9 (P < .001), change in average mBorg score of 0.2 to 2.0 (P < .001), and change in worst mBorg score as between 0.3 and 1.9 (P < .001). Corresponding effect size calculations lay within the 95% CIs for the regression analysis for each measure. CONCLUSIONS A 1-point change in NRS or mBorg score is a reasonable estimate of the MCID in average daily chronic breathlessness in CHF.

Abstract
Breathlessness or "shortness of breath," medically termed dyspnea, remains a devastating problem for many people and those who care for them. As a treatment intervention, administration of opioids to relieve breathlessness is an area where progress has been made with the development of an evidence base. As evidence in support of opioids has accumulated, so has our collective understanding about trial methodology, research collaboration, and infrastructure that is crucial to generate reliable research results for palliative care clinical settings. Analysis of achievements to date and what it takes to accomplish these studies provides important insights into knowledge gaps needing further research and practical insight into design of pharmacological and nonpharmacological intervention trials in breathlessness and palliative care. This article presents the current understanding of opioids for treating breathlessness, what is still unknown as priorities for future research, and highlights methodological issues for consideration in planned studies.

Abstract
BACKGROUND Dyspnea is a common, distressing symptom of cardiopulmonary and neuromuscular diseases. Since the ATS published a consensus statement on dyspnea in 1999, there has been enormous growth in knowledge about the neurophysiology of dyspnea and increasing interest in dyspnea as a patient-reported outcome. PURPOSE The purpose of this document is to update the 1999 ATS Consensus Statement on dyspnea. METHODS An interdisciplinary committee of experts representing ATS assemblies on Nursing, Clinical Problems, Sleep and Respiratory Neurobiology, Pulmonary Rehabilitation, and Behavioral Science determined the overall scope of this update through group consensus. Focused literature reviews in key topic areas were conducted by committee members with relevant expertise. The final content of this statement was agreed upon by all members. RESULTS Progress has been made in clarifying mechanisms underlying several qualitatively and mechanistically distinct breathing sensations. Brain imaging studies have consistently shown dyspnea stimuli to be correlated with activation of cortico-limbic areas involved with interoception and nociception. Endogenous and exogenous opioids may modulate perception of dyspnea. Instruments for measuring dyspnea are often poorly characterized; a framework is proposed for more consistent identification of measurement domains. CONCLUSIONS Progress in treatment of dyspnea has not matched progress in elucidating underlying mechanisms. There is a critical need for interdisciplinary translational research to connect dyspnea mechanisms with clinical treatment and to validate dyspnea measures as patient-reported outcomes for clinical trials.

Abstract
Background—
Left ventricular (LV) pacing alone may theoretically avoid deleterious effects of right ventricular pacing.
Methods and Results—
In a multicenter, double-blind, crossover trial, we compared the effects of LV and biventricular (BiV) pacing on exercise tolerance and LV remodeling in patients with an LV ejection fraction ≤35%, QRS ≥120 milliseconds, and symptoms of heart failure. A total of 211 patients were recruited from 11 centers. After a run-in period of 2 to 8 weeks, 121 qualifying patients were randomized to LV followed by BiV pacing or vice versa for consecutive 6-month periods. The greatest improvement in New York Heart Association class and 6-minute walk test occurred during the run-in phase before randomization. Exercise duration at 75% of peak V
o

(primary outcome) increased from 9.3±6.4 to 14.0±11.9 and 14.3±12.5 minutes with LV and BiV pacing, respectively, with no difference between groups (
P
=0.4327). LV ejection fraction improved from 24.4±6.3% to 31.9±10.8% and 30.9±9.8% with LV and BiV pacing, respectively, with no difference between groups (
P
=0.4530). Reductions in LV end-systolic volume were likewise similar (
P
=0.6788). The proportion of clinical responders (≥20% increase in exercise duration) to LV and BiV pacing was 48.0% and 55.1% (
P
=0.1615). Positive remodeling responses (≥15% reduction in LV end-systolic volume) were observed in 46.7% and 55.4% (
P
=0.0881). Overall, 30.6% of LV nonresponders improved with BiV and 17.1% of BiV nonresponders improved with LV pacing.
Conclusion—
LV pacing is not superior to BiV pacing. However, nonresponders to BiV pacing may respond favorably to LV pacing, suggesting a potential role as tiered therapy.

Abstract
PURPOSE OF REVIEW Breathlessness remains a frequent and burdensome symptom for individuals with life-limiting symptoms in both malignant and nonmalignant settings. As oxygen therapy is frequently given as part of the management of breathlessness and is associated with costs, treatment burden and potential dangers, it is timely to review the efficacy and appropriateness of palliative oxygen therapy. RECENT FINDINGS Despite the widespread use of oxygen therapy in clinical and community settings, data supporting this approach is sparse. The benefits of long-term oxygen therapy for severely hypoxaemic people with chronic obstructive pulmonary disease are proven; however, mounting evidence suggests that oxygen does not confer additional benefit over medical air for the relief of refractory breathlessness in people with mild or absent hypoxaemia. SUMMARY On the basis of the findings of this review, the routine use of palliative oxygen therapy without detailed assessment of pathogenesis and reversibility of symptoms cannot be justified. Promoting self-management strategies, such as cool airflow across the face, exercise and psychological support for patients and carers, should be considered before defaulting to oxygen therapy. If palliative oxygen therapy is considered for individuals with transient or mild hypoxaemia, a therapeutic trial should be conducted with clinical review after 3 days to assess the net clinical benefit and patient preference.
