Abstract
Importance: A recent systematic review and meta-analysis found that palliative care was not associated with improvement in quality of life (QOL) in terminal noncancer illness. Among potential reasons for a null effect, it is unclear if patient-reported outcome measures (PROMs) measuring QOL were derived or validated among populations with advanced life-limiting illness (ALLI). Objective: To systematically review the derivation and validation of QOL PROMs from a recent meta-analysis of randomized controlled trials (RCT) of palliative care interventions in people with terminal noncancer illness. Evidence Review: EMBASE, MEDLINE, and PsycINFO were searched from inception to January 8, 2023 for primary validation studies of QOL PROMs in populations with ALLI, defined as adults with a progressive terminal condition and an estimated median survival of less than or equal to one year. The primary outcome was the proportion of PROMs that were derived or validated in ≥1 ALLI population. Findings: Twenty-one unique studies of derivation (n = 13) and validation (n = 11, 3 studies evaluated both) provided data on 9657 participants (mean age 63 years, 50% female) across 15 unique QOL PROMs and subscales. Among studies of validation, 9 were in people with cancer (n = 2289, n = 5 PROMs), 1 in neurodegenerative disease (n = 23, n = 1 PROM), and 1 with mixed diseases (n = 248, n = 1 PROM). Across 15 QOL PROMs and subscales, 47% (n = 7) were derived or validated in an ALLI population. The majority of these seven PROMs were exclusively derived or validated among people with cancer (57%, n = 4). QOL PROMs such as Quality of Life at End of Life, EuroQoL-5 Dimension 5-level, and 36-item Short Form Survey demonstrated validity in more than one terminal noncancer illness. Conclusions: Most QOL PROMs that measured the effect of palliative care on QOL in RCTs were neither derived nor validated in an ALLI population. These findings raise questions about the inferences that palliative care does not improve QOL among people with terminal noncancer illness.

Abstract
INTRODUCTION The chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) score is widely used for evaluating the health status of patients diagnosed with COPD. The aim of this study was to identify which components of the CAT are associated with exacerbations in severe COPD patients. METHODS Using data from the Korean COPD Subgroup Study (KOCOSS), we identified 3,440 COPD patients, among which 1,027 patients are classified as having severe COPD based on spirometry results. The CAT scores on 8 items were evaluated and classified into respiratory and non-respiratory categories. We analyzed the association between CAT item scores and moderate-to-severe exacerbations during study enrollment and the following years. RESULTS Patients with a history of moderate-to-severe exacerbations had higher scores on non-respiratory CAT components. Longitudinal CAT scores on all items after enrollment were higher in the moderate-to-severe exacerbation group. Additionally, the frequency of severe exacerbations was associated with specific CAT components related to limited activities, confidence leaving home, sleeplessness, and energy. CONCLUSIONS This study revealed that the non-respiratory CAT component scores were statistically significant factors for predicting the moderate-to-severe exacerbation of severe COPD patients. Non-respiratory symptoms and functional limitations should be considered in patients with severe COPD. Interventions, such as pulmonary rehabilitation, may be needed to improve patients' overall well-being and prevent exacerbations.

Abstract
Background Patient-reported outcome measures (PROMs) may provide clinicians and researchers with direct insights into disease impact and patient well-being. We assessed whether selected PROMs and their domains are associated with baseline and longitudinal changes in lung function and can predict mortality in patients with fibrotic interstitial lung disease (f-ILD). Methods A single-centre prospective study of adult patients with f-ILD enrolled over 3 years was conducted assessing baseline and short-term changes in PROMs. Three questionnaires, the modified Medical Research Council dyspnoea scale (mMRC), Chronic Respiratory Questionnaire (CRQ) and Self-Management Ability Scale (SMAS-30) were administered at planned intervals and assessed for their association with baseline clinical findings, change in lung function (% predicted forced vital capacity (FVC%) and diffusion capacity of the lung for carbon monoxide (DLCO%)) and all-cause mortality. Results 199 patients were enrolled with a mean PROM follow-up of 9.6 months. When stratified by FVC% quartiles at presentation, lower mMRC (less dyspnoea), higher CRQ Physical and Emotional domain (better health-related quality of life) and higher total SMAS-30 scores (better self-management ability) were associated with higher FVC%. Short-term changes in all three PROMs appeared to be associated with changes in FVC% and DLCO%. Adjusted and unadjusted baseline and serial PROM changes were also predictive of mortality. Conclusions Baseline and serial assessments of PROMs were associated with changes in lung function and predicted death in patients with f-ILD. PROMs may strengthen comprehensive assessments of disease impact in clinical practice as well as support patient-centred outcomes in research.

Abstract
OBJECTIVES Noninvasive ventilation (NIV) is an effective treatment for chronic respiratory failure (CRF). Patient-centered outcomes need to be evaluated regularly and the S3-NIV questionnaire seems an applicable tool. We translated this short, self-administered questionnaire into a Dutch version and tested its construct validity and reliability. METHODS An observational study was conducted, including 127 stable long-term NIV users with CRF or complex sleep related breathing disorders due to different underlying diseases: chronic obstructive pulmonary disease (25%), slowly progressive neuromuscular disorders (35%), rapidly progressive neuromuscular disorders (12%) and 'other disorders' (28%) including complex sleep apnea and obesity hypoventilation syndrome. Construct validity and reliability were tested. RESULTS The Dutch version of the questionnaire was obtained after a translation and back-translation process. Internal consistency of the total score was good (Cronbach's α coefficient of 0.78) as well as for the 'respiratory symptoms' subdomain and the 'sleep and side effects' subdomain (Cronbach's α coefficient of 0.78 and 0.69, respectively). The reproducibility was excellent with an intraclass correlation of 0.89 (95% CI 0.87-0.93). Construct validity was good for the 'respiratory symptoms' subdomain. CONCLUSION The Dutch S3-NIV questionnaire is a reliable and valid tool to evaluate symptoms, sleep, and NIV related side effects in long-term NIV users.

Abstract
INTRODUCTION AND OBJECTIVES This systematic review summarized the evidence on the effects (benefits and harms) of pulmonary rehabilitation for individuals with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). MATERIAL AND METHODS We included randomized controlled trials comparing pulmonary rehabilitation to either active interventions or usual care regardless of setting. In March 2022, we searched MEDLINE, Scopus, CENTRAL, CINAHL and Web of Sciences, and trial registries. Record screening, data extraction and risk of bias assessment were undertaken by two reviewers. We assessed the certainty of the evidence using the GRADE approach. RESULTS This systematic review included 18 studies (n = 1465), involving a combination of mixed settings (8 studies), inpatient settings (8 studies), and outpatient settings (2 studies). The studies were at high risk of performance, detection, and reporting biases. Compared to usual care, pulmonary rehabilitation probably improves AECOPD-related hospital readmissions (relative risk 0.56, 95% CI 0.36 to 0.86; moderate certainty evidence) and cardiovascular submaximal capacity (standardized mean difference 0.73, 95% CI 0.48 to 0.99; moderate certainty evidence). Low certainty evidence suggests that pulmonary rehabilitation may be beneficial on re-exacerbations, dyspnoea, and impact of disease. The evidence regarding the effects of pulmonary rehabilitation on health-related quality of life and mortality is very uncertain (very low certainty evidence). CONCLUSION Our results indicate that pulmonary rehabilitation may be an effective treatment option for individuals with AECOPD, irrespective of setting. Our certainty in this evidence base was limited due to small studies, heterogeneous rehabilitation programs, numerous methodological weaknesses, and a poor reporting of findings that were inconsistent with each other. Trialists should adhere to the latest reporting standards to strengthen this body of evidence. REGISTRATION The study protocol was registered in Open Science Framework (https://osf.io/amgbz/).

Abstract
Home mechanical ventilation (HMV) is a treatment for chronic respiratory failure that has shown clinical and cost effectiveness in patients with underlying COPD, obesity-related respiratory failure and neuromuscular disease (NMD). By treating chronic respiratory failure with adequate adherence to HMV, improvement in patient-reported outcomes including health-related quality of life (HRQoL) have been evaluated using general and disease-specific quantitative, semi-qualitative and qualitative methods. However, the treatment response in terms of trajectory of change in HRQoL is not uniform across the restrictive and obstructive disease groups. In this review, the effect of HMV on HRQoL across the domains of symptom perception, physical wellbeing, mental wellbeing, anxiety, depression, self-efficacy and sleep quality in stable and post-acute COPD, rapidly progressive NMD (such as amyotrophic lateral sclerosis), inherited NMD (including Duchenne muscular dystrophy) and obesity-related respiratory failure will be discussed.

Abstract
BACKGROUND Inspiratory muscle training (IMT) aims to improve respiratory muscle strength and endurance. Clinical trials used various training protocols, devices and respiratory measurements to check the effectiveness of this intervention. The current guidelines reported a possible advantage of IMT, particularly in people with respiratory muscle weakness. However, it remains unclear to what extent IMT is clinically beneficial, especially when associated with pulmonary rehabilitation (PR). OBJECTIVES: To assess the effect of inspiratory muscle training (IMT) on chronic obstructive pulmonary disease (COPD), as a stand-alone intervention and when combined with pulmonary rehabilitation (PR). SEARCH METHODS We searched the Cochrane Airways trials register, CENTRAL, MEDLINE, Embase, PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL) EBSCO, Physiotherapy Evidence Database (PEDro) ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 20 October 2021. We also checked reference lists of all primary studies and review articles. SELECTION CRITERIA We included randomized controlled trials (RCTs) that compared IMT in combination with PR versus PR alone and IMT versus control/sham. We included different types of IMT irrespective of the mode of delivery. We excluded trials that used resistive devices without controlling the breathing pattern or a training load of less than 30% of maximal inspiratory pressure (PImax), or both. DATA COLLECTION AND ANALYSIS We used standard methods recommended by Cochrane including assessment of risk of bias with RoB 2. Our primary outcomes were dyspnea, functional exercise capacity and health-related quality of life. MAIN RESULTS: We included 55 RCTs in this review. Both IMT and PR protocols varied significantly across the trials, especially in training duration, loads, devices, number/ frequency of sessions and the PR programs. Only eight trials were at low risk of bias. PR+IMT versus PR We included 22 trials (1446 participants) in this comparison. Based on a minimal clinically important difference (MCID) of -1 unit, we did not find an improvement in dyspnea assessed with the Borg scale at submaximal exercise capacity (mean difference (MD) 0.19, 95% confidence interval (CI) -0.42 to 0.79; 2 RCTs, 202 participants; moderate-certainty evidence). We also found no improvement in dyspnea assessed with themodified Medical Research Council dyspnea scale (mMRC) according to an MCID between -0.5 and -1 unit (MD -0.12, 95% CI -0.39 to 0.14; 2 RCTs, 204 participants; very low-certainty evidence). Pooling evidence for the 6-minute walk distance (6MWD) showed an increase of 5.95 meters (95% CI -5.73 to 17.63; 12 RCTs, 1199 participants; very low-certainty evidence) and failed to reach the MCID of 26 meters. In subgroup analysis, we divided the RCTs according to the training duration and mean baseline PImax. The test for subgroup differences was not significant. Trials at low risk of bias (n = 3) demonstrated a larger effect estimate than the overall. The summary effect of the St George's Respiratory Questionnaire (SGRQ) revealed an overall total score below the MCID of 4 units (MD 0.13, 95% CI -0.93 to 1.20; 7 RCTs, 908 participants; low-certainty evidence). The summary effect of COPD Assessment Test (CAT) did not show an improvement in the HRQoL (MD 0.13, 95% CI -0.80 to 1.06; 2 RCTs, 657 participants; very low-certainty evidence), according to an MCID of -1.6 units. Pooling the RCTs that reported PImax showed an increase of 11.46 cmH2O (95% CI 7.42 to 15.50; 17 RCTs, 1329 participants; moderate-certainty evidence) but failed to reach the MCID of 17.2 cmH2O. In subgroup analysis, we did not find a difference between different training durations and between studies judged with and without respiratory muscle weakness. One abstract reported some adverse effects that were considered "minor and self-limited". IMT versus control/sham Thirty-seven RCTs with 1021 participants contributed to our second comparison. There was a trend towards an improvement when Borg was calculated at submaximal exercise capacity (MD -0.94, 95% CI -1.36 to -0.51; 6 RCTs, 144 participants; very low-certainty evidence). Only one trial was at a low risk of bias. Eight studies (nine arms) used the Baseline Dyspnea Index - Transition Dyspnea Index (BDI-TDI). Based on an MCID of +1 unit, they showed an improvement only with the 'total score' of the TDI (MD 2.98, 95% CI 2.07 to 3.89; 8 RCTs, 238 participants; very low-certainty evidence). We did not find a difference between studies classified as with and without respiratory muscle weakness. Only one trial was at low risk of bias. Four studies reported the mMRC, revealing a possible improvement in dyspnea in the IMT group (MD -0.59, 95% CI -0.76 to -0.43; 4 RCTs, 150 participants; low-certainty evidence). Two trials were at low risk of bias. Compared to control/sham, the MD in the 6MWD following IMT was 35.71 (95% CI 25.68 to 45.74; 16 RCTs, 501 participants; moderate-certainty evidence). Two studies were at low risk of bias. In subgroup analysis, we did not find a difference between different training durations and between studies judged with and without respiratory muscle weakness. Six studies reported theSGRQ total score, showing a larger effect in the IMT group (MD -3.85, 95% CI -8.18 to 0.48; 6 RCTs, 182 participants; very low-certainty evidence). The lower limit of the 95% CI exceeded the MCID of -4 units. Only one study was at low risk of bias. There was an improvement in life quality with CAT (MD -2.97, 95% CI -3.85 to -2.10; 2 RCTs, 86 participants; moderate-certainty evidence). One trial was at low risk of bias. Thirty-two RCTs reported PImax, showing an improvement without reaching the MCID (MD 14.57 cmH2O, 95% CI 9.85 to 19.29; 32 RCTs, 916 participants; low-certainty evidence). In subgroup analysis, we did not find a difference between different training durations and between studies judged with and without respiratory muscle weakness. None of the included RCTs reported adverse events. AUTHORS' CONCLUSIONS IMT may not improve dyspnea, functional exercise capacity and life quality when associated with PR. However, IMT is likely to improve these outcomes when provided alone. For both interventions, a larger effect in participants with respiratory muscle weakness and with longer training durations is still to be confirmed.

Abstract
Pulmonary rehabilitation (PR) improves health-related quality of life (HRQoL) and exercise capacity. Little is known about the impact of depression symptoms and exercise self-efficacy on improvements in these key PR outcomes. This study examined the impact of baseline depression status and change in depression symptoms (Beck Depression Inventory-II [BDI-II] score) over the course of PR on change in HRQoL assessed by the Chronic Respiratory Disease Questionnaire-Self Reported (CRQ-SR) and exercise capacity as measured by the 6-Minute Walk Test (6MWT). We also examined whether baseline exercise self-efficacy moderated the association between baseline depression symptoms and change in these key PR outcomes. We studied 112 US veterans (aged 70.38 ± 8.49 years) with chronic obstructive pulmonary disease (COPD) who completed PR consisting of twice-weekly 2-hour classes for 18 sessions. Depressed (BDI-II >13) and nondepressed (BDI-II ≤13) patients at baseline demonstrated comparable and significant improvement in CRQ-SR total score, subscales, and 6MWT. Greater reduction in depression over the course of treatment was significantly associated with greater improvement in CRQ-SR total score and the following subscales: fatigue, mastery, and emotional function. Change in depression did not predict change in 6MWT distance. Baseline exercise self-efficacy moderated the association between baseline depression symptoms and change in CRQ-SR fatigue. Specifically, when baseline exercise self-efficacy was <30.4, greater baseline depression was associated with less improvement in CRQ-SR fatigue. When baseline self-efficacy was >152.0, greater baseline depression was associated with greater improvement in CRQ-SR fatigue. PR programs should address mood and confidence to exercise given their impact on key PR outcomes.

Abstract
BACKGROUND Expectations can enhance the intensity and the neural processing of breathlessness. Previous breathlessness episodes may influence the perception of subsequent episodes because of psycho-traumatic consequences. In post-traumatic stress disorder, eye movement desensitization and reprocessing (EMDR) is the therapy of choice. AIMS AND OBJECTIVES We explored the hypothesis that EMDR in patients with chronic obstructive pulmonary disease (COPD) and previous severe breathlessness episodes, improves breathlessness mastery by decreasing the anxiety component. METHODS As we found no literature on previous research on this subject, we undertook a qualitative case series on four patients with COPD GOLD 4/D and refractory breathlessness who wished to undergo EMDR for psychotraumatic breathlessness episodes. Amongst others, we used the Chronic Respiratory Disease Questionnaire (CRQ) before and after EMDR, and semi-structured, face-to-face, in-depth interviews. RESULTS All patients had between three and five EMDR sessions. On CRQ, subset mastery, three patients had a large improvement and one patient a moderate improvement. On subset emotional functioning, three patients showed a large improvement and one showed no change. All patients made a distinction between 'regular' breathlessness and breathlessness intertwined with anxiety. They all stated that the anxiety component of their breathlessness diminished or disappeared. All four would recommend EMDR for other COPD patients. CONCLUSION There is ground for a randomized controlled clinical trial to test the effects of EMDR on breathlessness mastery in a subset of COPD patients with previous severe breathlessness episodes and high levels of anxiety.

Abstract
STUDY OBJECTIVES To determine efficacy and mechanisms of cognitive behavioral therapy for insomnia (CBT-I) and chronic obstructive pulmonary disease (COPD) education (COPD-ED) on clinical outcomes in adults with concurrent COPD and insomnia. METHODS We conducted a 2 × 2 factorial study to test the impact of CBT-I and COPD-ED delivered alone or in combination on severity of insomnia and fatigue, sleep, and dyspnea. Participants were randomized to 1 of 4 groups-group 1: CBT-I + attention control (AC; health videos, n = 27); group 2: COPD-ED + AC, n = 28; group 3: CBT-I + COPD-ED, n = 27; and group 4, AC only, n = 27. Participants received six 75-minute weekly sessions. Dependent variables included insomnia severity, sleep by actigraphy, fatigue, and dyspnea measured at baseline, immediately postintervention, and at 3 months postintervention. Presumed mediators of intervention effects included beliefs and attitudes about sleep, self-efficacy for sleep and COPD, and emotional function. RESULTS COPD patients (percent predicted forced expiratory volume in 1 second [FEV1pp] 67% ± 24% [mean ± standard deviation]), aged 65 ± 8 years, with insomnia participated in the study. Insomnia and sleep improved more in patients who received CBT-I than in those who did not, an effect that was sustained at 3 months postintervention and mediated by beliefs and attitudes about sleep. CBT-I was associated with clinically important improvements in fatigue and dyspnea. When CBT-I and COPD-ED were concurrently administered, effects on insomnia, fatigue, and dyspnea were attenuated. CONCLUSIONS CBT-I produced significant and sustained decreases in insomnia improved sleep and clinically important improvement in fatigue, and dyspnea. The combination of CBT-I and COPD-ED reduced CBT-I's effectiveness. Further research is needed to understand the mechanisms associated with effects of insomnia therapy on multiple symptoms in COPD.

Abstract
The Veterans Health Administration (VHA) is the largest integrated healthcare system in the United States (US) providing healthcare to an increasing number of middle-aged and older adults who remain at greater risk for chronic obstructive pulmonary disease (COPD) compared to their civilian counterparts. The VHA has obligated research funds, drafted clinical guidelines, and built programmatic infrastructure to support the diagnosis, treatment, and care management of Veterans with COPD. Despite these efforts, COPD remains a leading cause of morbidity and mortality in Veterans. This paper provides a narrative review of research conducted with US Veteran samples targeting improvement in COPD outcomes. We review key physiological, physical, and psychological health outcomes and intervention research that included US Veteran samples. We conclude with a discussion of directions for future research to continue advancing the treatment of COPD in Veterans and inform advancements in COPD research within and outside the VHA.

Early Diagnosis and Real-Time Monitoring of Regional Lung Function Changes to Prevent Chronic Obstructive Pulmonary Disease Progression to Severe Emphysema. J Clin Med 2021; 10:jcm10245811. [PMID: 34945107 PMCID: PMC8708661 DOI: 10.3390/jcm10245811] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 12/07/2021] [Accepted: 12/09/2021] [Indexed: 02/04/2023] Open
Abstract
First- and second-hand exposure to smoke or air pollutants is the primary cause of chronic obstructive pulmonary disease (COPD) pathogenesis, where genetic and age-related factors predispose the subject to the initiation and progression of obstructive lung disease. Briefly, airway inflammation, specifically bronchitis, initiates the lung disease, leading to difficulty in breathing (dyspnea) and coughing as initial symptoms, followed by air trapping and inhibition of the flow of air into the lungs due to damage to the alveoli (emphysema). In addition, mucus obstruction and impaired lung clearance mechanisms lead to recurring acute exacerbations causing progressive decline in lung function, eventually requiring lung transplant and other lifesaving interventions to prevent mortality. It is noteworthy that COPD is much more common in the population than currently diagnosed, as only 16 million adult Americans were reported to be diagnosed with COPD as of 2018, although an additional 14 million American adults were estimated to be suffering from COPD but undiagnosed by the current standard of care (SOC) diagnostic, namely the spirometry-based pulmonary function test (PFT). Thus, the main issue driving the adverse disease outcome and significant mortality for COPD is lack of timely diagnosis in the early stages of the disease. The current treatment regime for COPD emphysema is most effective when implemented early, on COPD onset, where alleviating symptoms and exacerbations with timely intervention(s) can prevent steep lung function decline(s) and disease progression to severe emphysema. Therefore, the key to efficiently combatting COPD relies on early detection. Thus, it is important to detect early regional pulmonary function and structural changes to monitor modest disease progression for implementing timely interventions and effectively eliminating emphysema progression. Currently, COPD diagnosis involves using techniques such as COPD screening questionnaires, PFT, arterial blood gas analysis, and/or lung imaging, but these modalities are limited in their capability for early diagnosis and real-time disease monitoring of regional lung function changes. Hence, promising emerging techniques, such as X-ray phase contrast, photoacoustic tomography, ultrasound computed tomography, electrical impedance tomography, the forced oscillation technique, and the impulse oscillometry system powered by robust artificial intelligence and machine learning analysis capability are emerging as novel solutions for early detection and real time monitoring of COPD progression for timely intervention. We discuss here the scope, risks, and limitations of current SOC and emerging COPD diagnostics, with perspective on novel diagnostics providing real time regional lung function monitoring, and predicting exacerbation and/or disease onset for prognosis-based timely intervention(s) to limit COPD–emphysema progression.

Abstract
Long-term oxygen therapy (LTOT) reduces hypoxaemia and mitigate systemic alterations in chronic obstructive pulmonary disease (COPD), however, it is related to inactivity and social isolation. Social participation and its related factors remain underexplored in individuals on LTOT. This study investigated social participation in individuals with COPD on LTOT and its association with dyspnoea, exercise capacity, muscle strength, symptoms of anxiety and depression, and quality of life. The Assessment of Life Habits (LIFE-H) assessed social participation. The modified Medical Research Council dyspnoea scale, the 6-Minute Step test (6MST) and handgrip dynamometry were used for assessments. In addition, participants responded to the Hospital Anxiety and Depression Scale (HADS) and the Chronic Respiratory Questionnaire (CRQ). Correlation coefficients and multivariate linear regression analyses were applied. Fifty-seven participants with moderate to very severe COPD on LTOT were included (71 ± 8 years, FEV1: 40 ± 17%predicted). Social participation was associated with dyspnoea (rs=-0.46, p < 0.01), exercise capacity (r = 0.32, p = 0.03) and muscle strength (r = 0.25, p = 0.05). Better participation was also associated with fewer depression symptoms (rs=-0.40, p < 0.01) and a better quality of life (r = 0.32, p = 0.01). Dyspnoea was an independent predictor of social participation (p < 0.01) on regression models. Restricted social participation is associated with increased dyspnoea, reduced muscle strength and exercise capacity. Better participation is associated with fewer depression symptoms and better quality of life in individuals with COPD on LTOT.

Predictors of Outpatient Pulmonary Rehabilitation Uptake, Adherence, Completion, and Treatment Response Among Male U.S. Veterans With Chronic Obstructive Pulmonary Disease. Arch Phys Med Rehabil 2021; 103:1113-1121.e1.

Abstract
OBJECTIVE To examine predictors of uptake (never start), adherence (drop out), and completion of pulmonary rehabilitation (PR), as well as PR treatment response based on minimal clinically important difference (MCID) on the 6-minute walk test (6MWT) distance and Chronic Respiratory Questionnaire-Self-Report (CRQ-SR). DESIGN Retrospective, cohort study. SETTING Veterans Health Administration. PARTICIPANTS U.S. veterans with chronic obstructive pulmonary disease (COPD) (N=253) referred to PR between 2010 and 2018. INTERVENTIONS Outpatient PR program. MAIN OUTCOME MEASURES Participants completed baseline (time 1) measures of depression (Beck Depression Inventory-II), health-related quality of life (CRQ-SR), self-efficacy (Exercise Self-Regulatory Efficacy Scale [Ex-SRES]), and COPD knowledge. Exercise capacity was assessed with the 6MWT. Participants who completed all 18 sessions of PR repeated assessments (time 2). Logistic regression models examined predictors of uptake, adherence, and completion of PR as well as treatment response based on MCID. RESULTS Participants were referred to PR with 24.90% never starting, 28.90% dropping out, and 46.20% completing. No differences emerged between never starters and dropouts. Having a history of any cancer increased the likelihood of completing PR (vs never starting; odds ratio [OR], 3.18; P=.003). Greater CRQ-SR dyspnea score, indicating less dyspnea, was associated with increased likelihood of completing PR (OR, 1.12; P=.006). Past smoking compared with current smoking was associated with increased likelihood of completion (OR, 3.89; P≤.002). Those without a history of alcohol use disorder had increased likelihood of completing PR (OR, 2.23; P=.048). Greater baseline 6MWT distance was associated with lower likelihood of achieving MCID in 6MWT (OR, 0.99; P<.001). Greater Ex-SRES was associated with decreased likelihood of achieving 6MWT MCID (OR, 0.98; P=.023). CONCLUSIONS Findings suggest that early psychoeducation on dyspnea management and smoking and alcohol cessation may increase completion of PR.

Opioids in patients with COPD and refractory dyspnea: literature review and design of a multicenter double blind study of low dosed morphine and fentanyl (MoreFoRCOPD). BMC Pulm Med 2021; 21:289. [PMID: 34507574 PMCID: PMC8431258 DOI: 10.1186/s12890-021-01647-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 08/30/2021] [Indexed: 12/02/2022] Open
Abstract
Background Refractory dyspnea or breathlessness is a common symptom in patients with advanced chronic obstructive pulmonary disease (COPD), with a high negative impact on quality of life (QoL). Low dosed opioids have been investigated for refractory dyspnea in COPD and other life-limiting conditions, and some positive effects were demonstrated. However, upon first assessment of the literature, the quality of evidence in COPD seemed low or inconclusive, and focused mainly on morphine which may have more side effects than other opioids such as fentanyl. For the current publication we performed a systematic literature search. We searched for placebo-controlled randomized clinical trials investigating opioids for refractory dyspnea caused by COPD. We included trials reporting on dyspnea, health status and/or QoL. Three of fifteen trials demonstrated a significant positive effect of opioids on dyspnea. Only one of four trials reporting on QoL or health status, demonstrated a significant positive effect. Two-thirds of included trials investigated morphine. We found no placebo-controlled RCT on transdermal fentanyl. Subsequently, we hypothesized that both fentanyl and morphine provide a greater reduction of dyspnea than placebo, and that fentanyl has less side effects than morphine.
Methods We describe the design of a robust, multi-center, double blind, double-dummy, cross-over, randomized, placebo-controlled clinical trial with three study arms investigating transdermal fentanyl 12 mcg/h and morphine sustained-release 10 mg b.i.d. The primary endpoint is change in daily mean dyspnea sensation measured on a numeric rating scale. Secondary endpoints are change in daily worst dyspnea, QoL, anxiety, sleep quality, hypercapnia, side effects, patient preference, and continued opioid use. Sixty patients with severe stable COPD and refractory dyspnea (FEV1 < 50%, mMRC ≥ 3, on optimal standard therapy) will be included.
Discussion Evidence for opioids for refractory dyspnea in COPD is not as robust as usually appreciated. We designed a study comparing both the more commonly used opioid morphine, and transdermal fentanyl to placebo. The cross-over design will help to get a better impression of patient preferences. We believe our study design to investigate both sustained-release morphine and transdermal fentanyl for refractory dyspnea will provide valuable information for better treatment of refractory dyspnea in COPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a chronic lung condition characterised by persistent respiratory symptoms and limited lung airflow, dyspnoea and recurrent exacerbations. Suboptimal therapy or non-adherence may result in limited effectiveness of pharmacological treatments and subsequently poor health outcomes. OBJECTIVES To determine the efficacy and safety of interventions intended to improve adherence to single or combined pharmacological treatments compared with usual care or interventions that are not intended to improve adherence in people with COPD. SEARCH METHODS We identified randomised controlled trials (RCTs) from the Cochrane Airways Trials Register, CENTRAL, MEDLINE and Embase (search date 1 May 2020). We also searched web-based clinical trial registers. SELECTION CRITERIA RCTs included adults with COPD diagnosed by established criteria (e.g. Global Initiative for Obstructive Lung Disease). Interventions included change to pharmacological treatment regimens, adherence aids, education, behavioural or psychological interventions (e.g. cognitive behavioural therapy), communication or follow-up by a health professional (e.g. telephone, text message or face-to-face), multi-component interventions, and interventions to improve inhaler technique. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. Working in pairs, four review authors independently selected trials for inclusion, extracted data and assessed risk of bias. We assessed confidence in the evidence for each primary outcome using GRADE. Primary outcomes were adherence, quality of life and hospital service utilisation. Adherence measures included the Adherence among Patients with Chronic Disease questionnaire (APCD). Quality of life measures included the St George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT) and Clinical COPD Questionnaire (CCQ). MAIN RESULTS We included 14 trials (2191 participants) in the analysis with follow-up ranging from six to 52 weeks. Age ranged from 54 to 75 years, and COPD severity ranged from mild to very severe. Trials were conducted in the USA, Spain, Germany, Japan, Jordan, Northern Ireland, Iran, South Korea, China and Belgium. Risk of bias was high due to lack of blinding. Evidence certainty was downgraded due to imprecision and small participant numbers. Single component interventions Six studies (55 to 212 participants) reported single component interventions including changes to pharmacological treatment (different roflumilast doses or different inhaler types), adherence aids (Bluetooth inhaler reminder device), educational (comprehensive verbal instruction), behavioural or psychological (motivational interview). Change in dose of roflumilast may result in little to no difference in adherence (odds ratio (OR) 0.67, 95% confidence interval (CI) 0.22 to 1.99; studies = 1, participants = 55; low certainty). A Bluetooth inhaler reminder device did not improve adherence, but comprehensive verbal instruction from a health professional did improve mean adherence (prescription refills) (mean difference (MD) 1.00, 95% CI 0.46 to 1.54). Motivational interview improved mean adherence scores on the APCD scale (MD 22.22, 95% CI 8.42 to 36.02). Use of a single inhaler compared to two separate inhalers may have little to no impact on quality of life (SGRQ; MD 0.80, 95% CI -3.12 to 4.72; very low certainty). A Bluetooth inhaler monitoring device may provide a small improvement in quality of life on the CCQ (MD 0.40, 95% CI 0.07 to 0.73; very low certainty). Single inhaler use may have little to no impact on the number of people admitted to hospital compared to two separate inhalers (OR 1.47, 95% CI 0.75 to 2.90; very low certainty). Single component interventions may have little to no impact on the number of people expereincing adverse events (very low certainty evidence from studies of a change in pharmacotherapy or use of adherence aids). A change in pharmacotherapy may have little to no impact on exacerbations or deaths (very low certainty). Multi-component interventions Eight studies (30 to 734 participants) reported multi-component interventions including tailored care package that included adherence support as a key component or included inhaler technique as a component. A multi-component intervention may result in more people adhering to pharmacotherapy compared to control at 40.5 weeks (risk ratio (RR) 1.37, 95% CI 1.18 to 1.59; studies = 4, participants = 446; I2 = 0%; low certainty). There may be little to no impact on quality of life (SGRQ, Chronic Respiratory Disease Questionnaire, CAT) (studies = 3; low to very low certainty). Multi-component interventions may help to reduce the number of people admitted to hospital for any cause (OR 0.37, 95% CI 0.22 to 0.63; studies = 2, participants = 877; low certainty), or COPD-related hospitalisations (OR 0.15, 95% CI 0.07 to 0.34; studies = 2, participants = 220; moderate certainty). There may be a small benefit on people experiencing severe exacerbations. There may be little to no effect on adverse events, serious adverse events or deaths, but events were infrequently reported and were rare (low to very certainty). AUTHORS' CONCLUSIONS Single component interventions (e.g. education or motivational interviewing provided by a health professional) can help to improve adherence to pharmacotherapy (low to very low certainty). There were slight improvements in quality of life with a Bluetooth inhaler device, but evidence is from one study and very low certainty. Change to pharmacotherapy (e.g. single inhaler instead of two, or different doses of roflumilast) has little impact on hospitalisations or exacerbations (very low certainty). There is no difference in people experiencing adverse events (all-cause or COPD-related), or deaths (very low certainty). Multi-component interventions may improve adherence with education, motivational or behavioural components delivered by health professionals (low certainty). There is little to no impact on quality of life (low to very low certainty). They may help reduce the number of people admitted to hospital overall (specifically pharmacist-led approaches) (low certainty), and fewer people may have COPD-related hospital admissions (moderately certainty). There may be a small reduction in people experiencing severe exacerbations, but evidence is from one study (low certainty). Limited evidence found no difference in people experiencing adverse events, serious adverse events or deaths (low to very low certainty). The evidence presented should be interpreted with caution. Larger studies with more intervention types, especially single interventions, are needed. It is unclear which specific COPD subgroups would benefit, therefore discussions between health professionals and patients may help to determine whether they will help to improve health outcomes.

Abstract
BACKGROUND Pulmonary rehabilitation benefits patients with chronic obstructive pulmonary disease (COPD), but gains are not maintained over time. Maintenance pulmonary rehabilitation has been defined as ongoing supervised exercise at a lower frequency than the initial pulmonary rehabilitation programme. It is not yet known whether a maintenance programme can preserve the benefits of pulmonary rehabilitation over time. Studies of maintenance programmes following pulmonary rehabilitation are heterogeneous, especially regarding supervision frequency. Furthermore, new maintenance models (remote and home-based) are emerging. OBJECTIVES To determine whether supervised pulmonary rehabilitation maintenance programmes improve health-related quality of life (HRQoL), exercise performance, and health care utilisation in COPD patients compared with usual care. Secondly, to examine in subgroup analyses the impact of supervision frequency and model (remote or in-person) during the supervised maintenance programme. SEARCH METHODS We searched the Cochrane Airways Trials Register, CENTRAL, MEDLINE, Embase, PEDro, and two additional trial registries platforms up to 31 March 2020, without restriction by language or type of publication. We screened the reference lists of all primary studies for additional references. We also hand-searched conference abstracts and grey literature through the Cochrane Airways Trials Register and CENTRAL. SELECTION CRITERIA We included only randomised trials comparing pulmonary rehabilitation maintenance for COPD with attention control or usual care. The primary outcomes were HRQoL, exercise capacity and hospitalisation; the secondary outcomes were exacerbation rate, mortality, direct costs of care, and adverse events. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts, extracted data, and assessed the risk of bias. Results data that were similar enough to be pooled were meta-analysed using a random-effects model, and those that could not be pooled were reported in narrative form. Subgroup analyses were undertaken for frequency of supervision (programmes offered monthly or less frequently, versus more frequently) and those using remote supervision (e.g. telerehabilitation versus face-to-face supervision). We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 21 studies (39 reports) with 1799 COPD patients. Participants ranged in age from 52 years to 88 years. Disease severity ranged from 24% to 88% of the predicted forced expiratory volume in one second. Programme duration ranged from four weeks to 36 months. In-person supervision was provided in 12 studies, and remote supervision was provided in six studies (telephone or web platform). Four studies provided a combination of in-person and remote supervision. Most studies had a high risk of performance bias due to lack of blinding of participants, and high risk of detection, attrition, and reporting bias. Low- to moderate-certainty evidence showed that supervised maintenance programmes may improve health-related quality of life at six to 12 months following pulmonary rehabilitation compared to usual care (Chronic Respiratory Questionnaire total score mean difference (MD) 0.54 points, 95% confidence interval (CI) 0.04 to 1.03, 258 participants, four studies), with a mean difference that exceeded the minimal important difference of 0.5 points for this outcome. It is possible that supervised maintenance could improve six-minute walk distance, but this is uncertain (MD 26 metres (m), 95% CI -1.04 to 52.84, 639 participants, 10 studies). There was little to no difference between the maintenance programme and the usual care group in exacerbations or all-cause hospitalizations, or the chance of death (odds ratio (OR) for mortality 0.73, 95% CI 0.36 to 1.51, 755 participants, six studies). Insufficient data were available to understand the impact of the frequency of supervision, or of remote versus in-person supervision. No adverse events were reported. AUTHORS' CONCLUSIONS This review suggests that supervised maintenance programmes for COPD patients after pulmonary rehabilitation are not associated with increased adverse events, may improve health-related quality of life, and could possibly improve exercise capacity at six to 12 months. Effects on exacerbations, hospitalisation and mortality are similar to those of usual care. However, the strength of evidence was limited because most included studies had a high risk of bias and small sample size. The optimal supervision frequency and models for supervised maintenance programmes are still unclear.

Abstract
Clinical prognostic tools are used to objectively predict outcomes in many fields of medicine. Whilst over 400 have been developed for use in chronic obstructive pulmonary disease (COPD), only a minority have undergone full external validation and just one, the DECAF score, has undergone an implementation study supporting use in clinical practice. Little is known about how such tools are used in the UK. We distributed surveys at two time points, in 2017 and 2019, to hospitals included in the Royal College of Physicians of London national COPD secondary care audit program. The survey assessed the use of prognostic tools in routine care of hospitalized COPD patients. Hospital response rates were 71/196 in 2017 and 72/196 in 2019. The use of the DECAF and PEARL scores more than doubled in decisions about unsupported discharge (7%-15.3%), admission avoidance (8.1%-17%) and readmission avoidance (4.8%-13.1%); it more than tripled (8.8%-27.8%) in decisions around hospital-at-home or early supported discharge schemes. In other areas, routine use of clinical prognostic tools was uncommon. In palliative care decisions, the use of the Gold Standards Framework Prognostic Indicator Guidance fell (5.6%-1.4%). In 2017, 43.7% of hospitals used at least one clinical prognostic tool in routine COPD care, increasing to 52.1% in 2019. Such tools can help challenge prognostic pessimism and improve care. To integrate these further into routine clinical care, future research should explore current barriers to their use and focus on implementation studies.Supplemental data for this article is available online at https://dx.doi.org/10.1080/15412555.2021.1959540.

Abstract
BACKGROUND Optimizing self-management is a key element in multidisciplinary pulmonary rehabilitation in patients with asthma or COPD. This observational study aimed to investigate the changes in self-management following pulmonary rehabilitation in subjects with chronic lung disease. METHODS Data were prospectively and routinely gathered at initial assessment and discharge in subjects taking part in a 12-week multidisciplinary out-patient pulmonary rehabilitation program. Measures of self-management included the Patient Activation Measure (PAM), the Health Education Impact Questionnaire (HEIQ) (8 subscales), a Self-Efficacy Questionnaire (2 subscales), the Lung Information Needs Questionnaire (LINQ), and the Health Literacy Questionnaire (HLQ) (9 subscales). Mean differences with 95% CI and effect sizes were computed. RESULTS A total of 70 subjects (62.9% women) were included, with a median age of 63.5 y; most of the subjects had been diagnosed with COPD (77%). Between admission and discharge, all measures of self-management increased significantly except for the HEIQ subscales of constructive attitudes and approaches, social integration and support, and health services navigation; and the HLQ subscale of social support for health. The largest improvements (effect size > 0.55) were seen for the PAM (0.57); the HEIQ subscales of health-directed behavior (0.71), self-monitoring and insight (0.62), and skill and technique acquisition (1.00); the HLQ subscales of having sufficient information to manage my health (1.21) and actively managing my health (0.66); and the LINQ (1.85). CONLCUSIONS Self-management, including activation, improved significantly in subjects with asthma or COPD who took part in a multidisciplinary pulmonary rehabilitation program.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is associated with dyspnoea, cough or sputum production (or both) and affects quality of life and functional status. More efficient approaches to alternative management that may include patients themselves managing their condition need further exploration in order to reduce the impact on both patients and healthcare services. Digital interventions may potentially impact on health behaviours and encourage patient engagement. OBJECTIVES To assess benefits and harms of digital interventions for managing COPD and apply Behaviour Change Technique (BCT) taxonomy to describe and explore intervention content. SEARCH METHODS We identified randomised controlled trials (RCTs) from the Cochrane Airways Trials Register (date of last search 28 April 2020). We found other trials at web-based clinical trials registers. SELECTION CRITERIA We included RCTs comparing digital technology interventions with or without routine supported self-management to usual care, or control treatment for self-management. Multi-component interventions (of which one component was digital self-management) compared with usual care, standard care or control treatment were included. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Two review authors independently selected trials for inclusion, extracted data, and assessed risk of bias. Discrepancies were resolved with a third review author. We assessed certainty of the evidence using the GRADE approach. Primary outcomes were impact on health behaviours, self-efficacy, exacerbations and quality of life, including the St George's Respiratory Questionnaire (SGRQ). The minimally important difference (MID) for the SGRQ is 4 points. Two review authors independently applied BCT taxonomy to identify mechanisms in the digital interventions that influence behaviours. MAIN RESULTS Fourteen studies were included in the meta-analyses (1518 participants) ranging from 13 to 52 weeks duration. Participants had mild to very severe COPD. Risk of bias was high due to lack of blinding. GRADE ratings were low to very low certainty due to lack of blinding and imprecision. Common BCT clusters identified as behaviour change mechanisms in interventions were goals and planning, feedback and monitoring, social support, shaping knowledge and antecedents. Digital technology intervention with or without routine supported self-management Interventions included mobile phone (three studies), smartphone applications (one study), and web or Internet-based (five studies). Evidence is very uncertain about effects on impact on health behaviours as measured by six-minute walk distance (6MWD) at 13 weeks (mean difference (MD) 26.20, 95% confidence interval (CI) -21.70 to 74.10; participants = 122; studies = 2) or 23 to 26 weeks (MD 14.31, 95% CI -19.41 to 48.03; participants = 164; studies = 3). There may be improvement in 6MWD at 52 weeks (MD 54.33 95% CI -35.47 to 144.12; participants = 204; studies = 2) but studies were varied (very low certainty). There may be no difference in self-efficacy on managing Chronic Disease Scale (SEMCD) or pulmonary rehabilitation adapted index of self-efficacy tool (PRAISE). Evidence is very uncertain. Quality of life may be slightly improved on the chronic respiratory disease questionnaire (CRQ) at 13 weeks (MD 0.45, 95% CI 0.01 to 0.90; participants = 123; studies = 2; low certainty), but is not clinically important (MID 0.5). There may be little or no difference at 23 or 52 weeks (low to very low certainty). There may be a clinical improvement on SGRQ total at 52 weeks (MD -26.57, 95% CI -34.09 to -19.05; participants = 120; studies = 1; low certainty). Evidence for COPD assessment test (CAT) and Clinical COPD Questionnaire (CCQ) is very uncertain. There may be little or no difference in dyspnoea symptoms (CRQ dyspnoea) at 13, 23 weeks or 52 weeks (low to very low certainty evidence) or mean number of exacerbations at 26 weeks (low-certainty evidence). There was no evidence for the number of people experiencing adverse events. Multi-component interventions Digital components included mobile phone (one study), and web or internet-based (four studies). Evidence is very uncertain about effects on impact on health behaviour (6MWD) at 13 weeks (MD 99.60, 95% CI -15.23 to 214.43; participants = 20; studies = 1). No evidence was found for self-efficacy. Four studies reported effects on quality of life (SGRQ and CCQ scales). The evidence is very uncertain. There may be no difference in the number of people experiencing exacerbations or mean days to first exacerbation at 52 weeks with a multi-component intervention compared to standard care. Evidence is very uncertain about effects on the number of people experiencing adverse events at 52 weeks. AUTHORS' CONCLUSIONS There is insufficient evidence to demonstrate a clear benefit or harm of digital technology interventions with or without supported self-management, or multi-component interventions compared to usual care in improving the 6MWD or self-efficacy. We found there may be some short-term improvement in quality of life with digital interventions, but there is no evidence about whether the effect is sustained long term. Dyspnoea symptoms may improve over a longer duration of digital intervention use. The evidence for multi-component interventions is very uncertain and as there is little or no evidence for adverse events, we cannot determine the benefit or harm of these interventions. The evidence base is predominantly of very low certainty with concerns around high risk of bias due to lack of blinding. Given that variation of interventions and blinding is likely to be a concern, future, larger studies are needed taking these limitations in consideration. Future studies are needed to determine whether the small improvements observed in this review can be applied to the general COPD population. A clear understanding of behaviour change through the BCT classification is important to gauge uptake of digital interventions and health outcomes in people with varying severity of COPD. Currently there is no guidance for interpreting BCT components of a digital intervention for changes to health outcomes. We could not interpret the BCT findings to the health outcomes we were investigating due to limited evidence that was of very low certainty. In future research, standardised approaches need to be considered when designing protocols to investigate effectiveness of digital interventions by including a standardised approach to BCT classification in addition to validated behavioural outcome measures that may reflect changes in behaviour.

Abstract
BACKGROUND Fatigue is a distressing symptom in patients with COPD. Little is known about the factors that contribute to fatigue in COPD. This review summarises existing knowledge on the prevalence of fatigue, factors related to fatigue and the instruments most commonly used to assess fatigue in COPD. METHODS Pubmed, PsycINFO, EMBASE, Cochrane and CINAHL databases were searched for studies from inception up to 7 January 2020 using the medical subject headings "COPD" and "Fatigue". Studies were reviewed in accordance with PRISMA guidelines. RESULTS 196 studies were evaluated. The prevalence of fatigue ranged from 17-95%. Age (r=-0.23 to r=0.27), sex (r=0.11), marital status (r=-0.096), dyspnoea (r=0.13 to r=0.78), forced expiatory volume in 1 s % predicted (r=-0.55 to r=-0.076), number of exacerbations (r=0.27 to r=0.38), number of comorbidities (r=0.10), number of medications (r=0.35), anxiety (r=0.36 to r=0.61), depression (r=0.41 to r=0.66), muscle strength (r=-0.78 to r=-0.45), functional capacity (r=-0.77 to r=-0.14) and quality of life (r=0.48 to r=0.77) showed significant associations with fatigue. CONCLUSIONS Fatigue is a prevalent symptom in patients with COPD. Multiple physical and psychological factors seem to be associated with fatigue. Future studies are needed to evaluate these underlying factors in integral analyses in samples of patients with COPD.

Estimation of minimal clinically important difference for quadriceps and inspiratory muscle strength in older outpatients with chronic obstructive pulmonary disease: a prospective cohort study. Phys Ther Res 2020; 24:35-42.

Abstract
OBJECTIVE To estimate the minimal clinically important difference (MCID) of quadriceps and inspiratory muscle strength after a home-based pulmonary rehabilitation program (PRP) in chronic obstructive pulmonary disease (COPD). METHOD Eighty-five COPD patients were included. Quadriceps maximal voluntary contraction (QMVC) was measured. We measured maximal inspiratory mouth pressure (PImax), the 6-minute walk distance (6MWD), the chronic respiratory questionnaire (CRQ) and the modified Medical Research Council dyspnoea score (mMRC). All measurements were conducted at baseline and at the end of the PRP. The MCID was calculated using anchor-based (using 6MWD, CRQ, and mMRC as possible anchor variables) and distribution-based (half standard deviation and 1.96 standard error of measurement) approaches. Changes in the five variables were compared in patients with and without changes in QMVC or PImax >MCID for each variable. RESULTS Sixty-nine COPD patients (age 75±6 years) were analysed. QMVC improved by 2.4 (95%CI 1.1-3.7) kgf, PImax by 5.8 (2.7-8.8) cmH2O, 6MWD by 21 (11-32) meters and CRQ by 3.9 (1.6-6.3) points. The MCID of QMVC and PImax was 3.3-7.5 kgf and 17.2-17.6 cmH2O, respectively. The MCID of QMVC (3.3 kgf) could differentiate individuals with significant improvement in 6MWD and PImax from those without. CONCLUSION The MCID of QMVC (3.3 kgf) can identify a meaningful change in quadriceps muscle strength after a PRP. The MCID of PImax (17.2 cmH2O) should be used with careful consideration, because the value is estimated using distributionbased method.

Abstract
Background: The aim of the present work is the elaboration of a systematic review of existing research on physical fitness, self-efficacy for physical exercise, and quality of life in adulthood. Method: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines, and based on the findings in 493 articles, the final sample was composed of 37 articles, which were reviewed to show whether self-efficacy has previously been studied as a mediator in the relationship between physical fitness and quality of life in adulthood. Results: The results indicate that little research exists in relation to healthy, populations with the majority being people with pathology. Physical fitness should be considered as a fundamental aspect in determining the functional capacity of the person. Aerobic capacity was the most evaluated and the 6-min walk test was the most used. Only one article shows the joint relationship between the three variables. Conclusions: We discuss the need to investigate the mediation of self-efficacy in relation to the value of physical activity on quality of life and well-being in the healthy adult population in adult life.

Abstract
AIMS To analyse the effects of nurse-driven self-management (SM) programs on physical and psychosocial health variables in people with chronic obstructive pulmonary disease (COPD). DESIGN A systematic review and meta-analysis. DATA SOURCES An exhaustive scanning of PubMed, Cochrane Controlled Register of Trials, CINAHL, ScienceDirect and Medline databases between January 2010-December 2019 was conducted for this meta-analysis. REVIEW METHODS Randomized controlled trials (RCTs) related to nurse-driven SM programs in COPD population were included. The standardized mean differences with 95% confidence intervals were determined for the main variables and heterogeneity was analysed using the I2 test. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used. RESULTS Twelve studies were included. The results indicated that significant difference in physical health scores based on COPD Assessment Tool (CAT) and walking distance according to the 6-min walk distance (6MWD) test in the intervention groups compared with the control groups. About psychosocial health findings, the quality of life increased and the Hospital Anxiety and Depression Scale (HADS) scores decreased following SM programs. All of the studies had good quality (varying from 5-8 points) according to The Modified Jadad Scale. CONCLUSION Nurse-driven SM programs may contribute to prognosis in patients with COPD. Due to methodological weaknesses in the included trials, high-quality RCTs are needed to better determine the effects of nurse-driven SM programs in the management of COPD. Nurse-driven SM programs may be employed as a useful strategy to improve health status and QOL and psychosocial health in the COPD population, as well. IMPACT Current evidence shows that nurse-driven SM programs could be safely integrated into the clinical practice for patients with COPD. Future studies are warranted that evaluating the effects of nurse-driven SM programs on other frequently observed COPD symptoms such as dyspnoea, fatigue and sleep disturbance.

Efficacy of adding activity of daily living simulation training to traditional pulmonary rehabilitation on dyspnea and health-related quality-of-life. PLoS One 2020; 15:e0237973. [PMID: 32853275 PMCID: PMC7451521 DOI: 10.1371/journal.pone.0237973] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 08/06/2020] [Indexed: 12/14/2022] Open
Abstract
Introduction Exercise modalities offered as part of traditional pulmonary rehabilitation (PR) do not always translate to successful performance of Activities of Daily Living (ADL) and may hinder gains in patient’s sense of well-being. Data is lacking on the efficacy of incorporation of ADL-focused training in PR. The aim of this study was to determine the impact of incorporation of ADL simulation and energy-conservation training in PR as part of a quality-initiative on health-related-quality-of-life (HRQOL), dyspnea, fatigue, and six-minute-walk-test among PR patients. Methods Retrospective study where medical records of consecutive patients with chronic respiratory diseases who completed PR from 2016 to 2018 were reviewed. ADL-focused energy-conservation training was added to traditional PR in September 2017 by replacing three monthly sessions of traditional PR with energy-conservation training as a quality-improvement-initiative. The change from baseline on HRQOL measured by COPD assessment test (CAT), six-minute-walk-test, MMRC dyspnea score and CRQ-dyspnea and CRQ-fatigue questionnaires, were compared between patients who received traditional PR versus energy-conservation PR. Within and between group differences were calculated via repeated-measures ANOVA. Results The baseline characteristics of 91 patients who participated in traditional PR versus energy-conservation PR (n = 85) were similar (mean age = 68.6±10.4 years, 49% men). While improvement from baseline was similar and significant for both groups for MMRC, CRQ-dyspnea and CRQ-fatigue scores, and six-minute walk test, patients who participated in energy-conservation PR had significantly higher improvement in HRQOL CAT scores (p = 0.01) than those who completed traditional PR. Conclusion Tailoring patient’s training programs to include energy-conservation training exercises specific to ADL in PR improved HRQOL over traditional PR in patients with chronic respiratory diseases despite no significant change in functional status. Future randomized-controlled trials will be needed to confirm these initial findings.

Abstract
Palliative care was initially developed for patients with advanced cancer. The concept has evolved and now encompasses any life-threatening chronic disease. Studies carried out to compare end-of-life symptoms have shown that although symptoms such as pain and dyspnea are as prevalent in patients with lung disease as in patients with cancer, the former receive less palliative treatment than do the latter. There is a need to refute the idea that palliative care should be adopted only when curative treatment is no longer possible. Palliative care should be provided in conjunction with curative treatment at the time of diagnosis, by means of a joint decision-making process; that is, the patient and the physician should work together to plan the therapy, seeking to improve quality of life while reducing physical, psychological, and spiritual suffering.

Abstract
Physical inactivity and sleep disturbance are more problematic in patients with chronic obstructive pulmonary disease (COPD) than in healthy individuals. The purpose of the study was to identify impacts of nighttime sleep on next-day physical activity in COPD patients. The study included 52 COPD patients reporting disturbed sleep. Sleep and physical activity were measured using an accelerometer for 5 days. Increased sleep latency was associated with less next-day physical activity during the afternoon (4-6 p.m.). Greater waking duration/times were associated with less next-morning (6-8 a.m.) physical activity. Greater total sleep time was associated with less next-morning (12-9 a.m.) physical activity, and greater sleep efficiency was associated with less next-morning (1-3 a.m.) and more next-evening (6-7 p.m.) physical activity. Results suggest that sleep disturbance had varying influences on next-day hourly physical activity. These results support the potential value of sleep management in promoting physical activity in COPD patients.

Abstract
AIM To examine the effect of a 6-month, smartphone app-based self-management program for people with chronic obstructive pulmonary disease (COPD). BACKGROUND Technological interventions have been used for chronic disease management, but the effect of a self-management program using a smartphone app has not been evaluated in people with COPD. METHODS For this randomized controlled trial, patients with COPD (N = 44) were recruited in pulmonary medicine outpatient clinics at two, metropolitan, tertiary care, academic hospitals. Eligible participants were randomized into two groups and received group education and exercise sessions in the first month of the 6-month intervention. Participants in the experimental group received a smartphone app-based self-management program, which included education, exercises, self-monitoring of symptoms and exercise, and social support. Participants in the control group received one call a month from the research staff. Self-care behavior was measured as a primary outcome. All measures were administered at baseline and at 6 months. RESULTS After randomization, the experimental group numbered 22, the control group numbered 20, and 2 participants dropped out. Significant differences between groups were found in change score for self-care behavior, total activity count per wear time, and percent time spent in moderate-to-vigorous physical activity over 6 months. CONCLUSION A self-management program, using a smartphone app, can effect behavioral change in people with COPD. This program could be a boon to patients with COPD who have limited access to a health care provider, no opportunities for pulmonary rehabilitation, and frequent exacerbations.

Abstract
Introduction Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive lung disease that causes breathlessness and cough that worsen over time, limiting daily activities and negatively impacting quality of life. Although treatments are now available that slow the rate of lung function decline, trials of these treatments have failed to show improvement in symptoms or quality of life. There is an immediate unmet need for evidenced-based interventions that improve patients' symptom burden and make a difference to everyday living. This study aims to assess the feasibility of conducting a definitive randomised controlled trial of a holistic, complex breathlessness intervention in people with IPF. Methods and analysis The trial is a two-centre, randomised controlled feasibility trial of a complex breathlessness intervention compared with usual care in patients with IPF. 50 participants will be recruited from secondary care IPF clinics and randomised 1:1 to either start the intervention within 1 week of randomisation (fast-track group) or to receive usual care for 8 weeks before receiving the intervention (wait-list group). Participants will remain in the study for a total of 16 weeks. Outcome measures will be feasibility outcomes, including recruitment, retention, acceptability and fidelity of the intervention. Clinical outcomes will be measured to inform outcome selection and sample size calculation for a definitive trial. Ethics and dissemination Yorkshire and The Humber – Bradford Leeds Research Ethics Committee approved the study protocol (REC 18/YH/0147). Results of the main trial and all secondary end-points will be submitted for publication in a peer-reviewed journal. Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive lung disease. This study protocol describes the BREEZE-IPF study: a feasibility, randomised controlled trial of a holistic, complex breathlessness intervention in IPF.http://bit.ly/33eF9im

Abstract
Latent growth models are often used to measure individual trajectories representing change over time. The characteristics of the individual trajectories depend on the variability in the longitudinal outcomes. In many medical and epidemiological studies, the individual health outcomes cannot be observed directly and are indirectly observed through indicators (i.e. items of a questionnaire). An item response theory or a classical test theory measurement model is required, but the choice can influence the latent growth estimates. In this study, under various conditions, this influence is directly assessed by estimating latent growth parameters on a common scale for item response theory and classical test theory using a novel plausible value method in combination with Markov chain Monte Carlo. The latent outcomes are considered missing data and plausible values are generated from the corresponding posterior distribution, separately for item response theory and classical test theory. These plausible values are linearly transformed to a common scale. A Markov chain Monte Carlo method was developed to simultaneously estimate the latent growth and measurement model parameters using this plausible value technique. It is shown that estimated individual trajectories using item response theory, compared to classical test theory to measure outcomes, provide a more detailed description of individual change over time, since item response patterns (item response theory) are more informative about the health measurements than sum scores (classical test theory).

Abstract
The objective of this study is to review available functional status measures (FSMs) validated for use in the chronic obstructive pulmonary disease (COPD) population and categorizing the measures by their commonalities to formulate a framework that supports clinicians in the selection and application of FSMs. A literature review identifying valid and reliable measures of functional status for people with COPD was undertaken. Measures were thematically analyzed and categorized to develop a framework for clinical application. A variety of measures of activity levels exist, with 35 included in this review. Thematic categorization identified five categories of measures: daily activity, impact, surrogate, performance-based, and disability-based measures. The vast variety of FSMs available for clinicians to apply with people who have COPD may be overwhelming, and selection must be thoughtfully based on the nature of the population being studied/evaluated, and aims of evaluation being conducted, not simply as a standard measure used at the institution. Psychometric testing is a critical feature to a strong instrument and issues of reliability, validity, and responsiveness need to be understood prior to measurement use. Contextual nature of measures such as language used and activities measured is also important. A categorical framework to support clinicians in the selection and application of FSMs has been presented in this article.

Abstract
Background Concerning COPD, pulmonary rehabilitation (PR) has a positive effect on disease progression and mortality, is cost-effective, and is a part of recommendations of international guidelines. Only a minority of patients profit from conventional PR due to a lack of resources, physicians’ guideline adherence, or patients’ motivation. Novel digital therapies like Kaia COPD, a smartphone application that digitizes PR in COPD, are promising solutions to fill this void. Methods Kaia COPD provides a digital version of PR and is certified as a class-I medical device in the European Union. We investigated anonymized data from users of the Kaia COPD app on in-app retention and the change in health-related quality of life (COPD assessment test and Chronic Respiratory Disease Questionnaire [CRQ]) during a period of 20 exercise days with the app. Results Of 349 app downloads, 56 users fulfilled inclusion criteria and 34 (61%) had finished day 20 at the time of analysis and were included. Users took 33±11 days to complete the 20-day core program. Users finishing the program reduced their COPD assessment test scores (mean 2.5 units from 21.6±7.7 to 19.1±8.4 units, P=0.008). In finishers, there was a statistically significant effect above the minimum clinically important threshold of the CRQ score on the domains of fatigue, mastery, and emotional function. There was a statistically significant but not clinically relevant effect on the domain of dyspnea of CRQ. Conclusion Digitalizing PR with a smartphone app is feasible and accepted by selected patients. The app leads to short-term improvement of health-related quality of life in patients completing a 20-day core program. Due to its observational character, this study has several methodological limitations and was intended to show the feasibility and to extrapolate effect sizes for planned prospective randomized-controlled trials to confirm these findings.

Abstract
In addition to dyspnea and fatigue, pain is a prevalent symptom in chronic obstructive pulmonary disease (COPD). Understanding the relative prevalence, magnitude, and interference with aspects of daily living of these symptoms can improve COPD management. Therefore, the purposes of this study were to: (1) compare the prevalence and magnitude of dyspnea, fatigue, and pain and how each limits aspects of daily living; (2) determine the association between pain and the other two symptoms; and (3) assess the impact of these symptoms on quality of life in COPD. Participants were recruited from pulmonary rehabilitation programs. Pain, dyspnea, and fatigue were measured using the Brief Pain Inventory (BPI), Brief Fatigue Inventory (BFI), and Dyspnea Inventory (DI), respectively. Quality of life was measured using the Clinical COPD Questionnaire (CCQ). The prevalence of dyspnea, fatigue, and pain were 93%, 77%, and 74%, respectively. Individuals with COPD reported similar severity scores of the three symptoms. Dyspnea interfered with general activity more than pain (F1.7,79.9 = 3.1, p < 0.05), whilst pain interfered with mood (F1.8, 82.7 = 3.6, p < 0.05) and sleep (F1,46 = 7.4, p < 0.01) more than dyspnea and fatigue. These three symptoms were moderately-to-highly correlated with each other (ρ = 0.49-0.78, p < 0.01) and all individually impacted quality of life. In summary, pain is a common symptom in addition to dyspnea and fatigue in COPD; all three interfere similarly among aspects of daily living with some exceptions. Accordingly, management of COPD should include a multifaceted approach that addresses pain as well as dyspnea and fatigue.

Abstract
Chronic breathlessness is a common source of psychological and physical stress in patients with advanced or progressive disease, suggesting that hypothalamic-pituitary-adrenal (HPA) axis dysregulation may be prevalent. The aim of this study was to measure the salivary diurnal cortisol profile in patients receiving supportive and palliative care for a range of malignant and non-malignant conditions and to compare the profile of those experiencing moderate-to-severe disability due to breathlessness against that of patients with mild/no breathlessness and that of healthy controls. Saliva samples were collected over two consecutive weekdays at 3, 6, and 12h after awakening in 49 patients with moderate-to-severe breathlessness [Medical Research Council (MRC) dyspnoea grade ≥3], 11 patients with mild/no breathlessness (MRC dyspnoea grade ≤2), and 50 healthy controls. Measures of breathlessness, stress, anxiety, depression, wellbeing and sleep were examined concomitantly. The diurnal cortisol slope (DCS) was calculated for each participant by regressing log-transformed cortisol values against collection time. Mean DCS was compared across groups using ANCOVA. Individual slopes were categorised into one of four categories: consistent declining, consistent flat, consistent ascending and inconsistent. Controlling for age, gender and socioeconomic status, the mean DCS was significantly flatter in patients with moderate-to-severe breathlessness compared to patients with mild/no breathlessness and healthy controls [F (2, 103)=45.64, p<0.001]. Furthermore, there was a higher prevalence of flat and ascending cortisol profiles in patients with moderate-to-severe breathlessness (23.4%) compared to healthy controls (0%). The only variable which correlated significantly with DCS was MRC dyspnoea grade (rs=0.29, p<0.05). These findings suggest that patients with moderate-to-severe breathlessness have evidence of HPA axis dysregulation and that this dysregulation may be related to the functional disability imposed by breathlessness.

Abstract
Our aim was to comprehensively validate the 1-min sit-to-stand (STS) test in chronic obstructive pulmonary disease (COPD) patients and explore the physiological response to the test.We used data from two longitudinal studies of COPD patients who completed inpatient pulmonary rehabilitation programmes. We collected 1-min STS test, 6-min walk test (6MWT), health-related quality of life, dyspnoea and exercise cardiorespiratory data at admission and discharge. We assessed the learning effect, test-retest reliability, construct validity, responsiveness and minimal important difference of the 1-min STS test.In both studies (n=52 and n=203) the 1-min STS test was strongly correlated with the 6MWT at admission (r=0.59 and 0.64, respectively) and discharge (r=0.67 and 0.68, respectively). Intraclass correlation coefficients (95% CI) between 1-min STS tests were 0.93 (0.83-0.97) for learning effect and 0.99 (0.97-1.00) for reliability. Standardised response means (95% CI) were 0.87 (0.58-1.16) and 0.91 (0.78-1.07). The estimated minimal important difference was three repetitions. End-exercise oxygen consumption, carbon dioxide output, ventilation, breathing frequency and heart rate were similar in the 1-min STS test and 6MWT.The 1-min STS test is a reliable, valid and responsive test for measuring functional exercise capacity in COPD patients and elicited a physiological response comparable to that of the 6MWT.

Abstract
This review aimed to assess the impact of behavioural therapy for insomnia administered alone (BT-I) or in combination with cognitive techniques (cognitive-behavioural therapy for insomnia, CBT-I) on depressive and fatigue symptoms using network meta-analysis. PubMed, Scopus and Web of Science were searched from 1986 to May 2015. Studies were included if they incorporated sleep restriction, a core technique of BT-I treatment, and an adult insomnia sample, a control group and a standardised measure of depressive and/or fatigue symptoms. Face-to-face, group, self-help and internet therapies were all considered. Forty-seven studies were included in the meta-analysis. Eleven classes of treatment or control conditions were identified in the network. Cohen's d at 95% confidence interval (CI) was calculated to assess the effect sizes of each treatment class as compared with placebo. Results showed significant effects for individual face-to-face CBT-I on depressive (d = 0.34, 95% CI: 0.06-0.63) but not on fatigue symptoms, with high heterogeneity between studies. The source of heterogeneity was not identified even after including sex, age, comorbidity and risk of bias in sensitivity analyses. Findings highlight the need to reduce variability between study methodologies and suggest potential effects of individual face-to-face CBT-I on daytime symptoms.

Abstract
CONTEXT Dyspnea, fatigue, and pain are common in individuals with chronic obstructive pulmonary disease (COPD). However, questionnaires with a similar format are not available to assess their relative severity and interference. OBJECTIVES To determine the reliability and validity of the Brief Fatigue Inventory (BFI) and Dyspnea Inventory (DI) in COPD patients who attend pulmonary rehabilitation programs. METHODS Participants were recruited from four pulmonary rehabilitation programs to complete a survey package containing: the Chronic Respiratory Questionnaire (CRQ), BFI, and DI; and one week later, to complete the BFI and DI. Retrospective data of the CRQ, BFI, and DI were retrieved from one of the programs. RESULTS For the prospective component, there was an 85% response rate (n = 91) for the first package and 83.5% response rate (n = 76) for the second package. Retrospectively, CRQ, BFI, and DI data were retrieved from 48 charts. The BFI and DI demonstrated excellent internal consistency (Cronbach alpha = 0.96 both), and high test-retest reliability (intraclass correlation3,1 = 0.86 and 0.91, respectively). By comparison to the fatigue and dyspnea domains of the CRQ, the BFI showed high concurrent validity (ρ = -0.83), whereas the DI showed moderate (ρ = -0.57) to high (ρ = -0.78) concurrent validity. Factor analysis provided evidence that the items in the BFI and DI measured the intended constructs. CONCLUSION The BFI and DI are valid and reliable measures to evaluate fatigue and dyspnea in COPD patients and could be used concurrently with the Brief Pain Inventory to inform the relative severity and interference of these common symptoms in COPD.

Efficacy and mechanisms of behavioral therapy components for insomnia coexisting with chronic obstructive pulmonary disease: study protocol for a randomized controlled trial. Trials 2016; 17:258.

Abstract
BACKGROUND Difficulty falling asleep, staying asleep or poor-quality sleep (insomnia) is common in people with chronic obstructive pulmonary disease (COPD). Insomnia is related to greater mortality and morbidity, with four times the risk of mortality for sleep times below 300 min. However, insomnia medications are used with caution in COPD due to their potential adverse effects. While cognitive behavioral therapy for insomnia (CBT-I) is effective for people with primary insomnia and people with other chronic illnesses, the efficacy and mechanisms of action of such a therapy are yet unclear in people with both insomnia and COPD. The purpose of this study is to rigorously test the efficacy of two components of insomnia therapy - CBT-I and COPD education (COPD-ED) - in people with coexisting insomnia and COPD, and to identify mechanisms responsible for therapy outcomes. The rationale for the proposed study is that once the efficacy and mechanisms of CBT-I and COPD-ED are known, new and innovative approaches for insomnia coexisting with COPD can be developed to non-pharmacologically minimize insomnia and fatigue, thereby leading to longer, higher-quality and more productive lives for people with COPD, and reduced societal cost due to the effects of insomnia. METHODS We are conducting a randomized, controlled, parallel-group (N = 35 each group) comparison of CBT-I, COPD-ED and non-COPD, non-sleep health education Attention Control (AC) using a highly efficient four-group design. Arm 1 comprises 6 weekly sessions of CBT-I + AC; Arm 2 = 6 weekly sessions of COPD-ED + AC; Arm 3 = 6 weekly sessions of CBT-I + COPD-ED; and Arm 4 = 6 weekly sessions of AC. This design will allow completion of the following specific aims: (1) to determine the efficacy of individual treatment components, CBT-I and COPD-ED, on insomnia and fatigue, (2) to define the mechanistic contributors to the outcomes after CBT-I and COPD-ED. DISCUSSION The research is innovative because it represents a new and substantive departure from the usual insomnia therapy, namely by testing traditional CBT-I with education to enhance outcomes. The work proposed in aims 1 and 2 will provide systematic evidence of the efficacy and mechanisms of components of a novel approach to insomnia comorbid with COPD. Such results are highly likely to provide new approaches for preventive and therapeutic interventions for insomnia and fatigue in COPD. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01973647 .

Abstract
BACKGROUND Overuse of short-acting beta-agonists (SABA) is described in asthma, but little is known about overuse of SABA in chronic obstructive pulmonary disease (COPD). METHODS Prospective 3-month cohort study of patients with moderate-to-severe COPD who were provided a portable electronic inhaler sensor to monitor daily SABA use. Subjects wore a pedometer for 3 seven-day periods and were asked to complete a daily diary of symptoms and inhaler use. Overuse was defined as >8 actuations of their SABA per day while clinically stable. RESULTS Among 32 participants, 15 overused their SABA inhaler at least once (mean 8.6 ± 5.0 puffs/day), and 6 overused their inhaler more than 50% of monitored days. Compared to those with no overuse, overusers had greater dyspnea (modified Medical Research Council Dyspnea Scale: 2.7 vs. 1.9, p = 0.02), were more likely to use home oxygen (67% vs. 29%, p = 0.04), and were more likely to be on maximal inhaled therapy (long-acting beta-agonist, long-acting antimuscarinic agent, and an inhaled steroid: 40% vs. 6%, p = 0.03), and most had completed pulmonary rehabilitation (67% vs. 0%, p < 0.001). However, 27% of overusers of SABA were not on guideline-concordant COPD therapy. CONCLUSIONS Overuse of SABA was common and associated with increased disease severity and symptoms, even though overusers were on more COPD-related inhalers and more had completed pulmonary rehabilitation. More research is needed to understand factors associated with inhaler overuse and how to improve correct inhaler use.

Abstract
BACKGROUND Cognitive impairment is increasingly being found to be a common comorbidity in chronic obstructive pulmonary disease (COPD). This study sought to understand the relationship of comprehensively measured cognitive function with COPD severity, quality of life, living situation, health care utilization, and self-management abilities. METHODS Subjects with COPD were recruited from the outpatient pulmonary clinic. Cognitive function was assessed using the Montreal Cognitive Assessment (MOCA). Self-management abilities were measured using the Self Management Ability Score 30. Quality of life was measured using the Chronic Respiratory Disease Questionnaire. Pearson correlation was used to assess the bivariate association of the MOCA with other study measures. Multivariate analysis was completed to understand the interaction of the MOCA and living situation on COPD outcomes of hospitalization, quality of life, and self-management ability. RESULTS This study included 100 participants of mean age 70±9.4 years (63% male, 37% female) with COPD (mean FEV1 [forced expiratory volume in 1 second] percentage predicted 40.4±16.7). Mean MOCA score was 23.8±3.9 with 63% of patients having mild cognitive impairment. The MOCA was negatively correlated with age (r=-0.28, P=0.005) and positively correlated with education (r=+0.24, P=0.012). There was no significant correlation between cognitive function and exacerbations, emergency room (ER) visits, or hospitalizations. There was no association between the MOCA score and self-management abilities or quality of life. We tested the interaction of living situation and the MOCA with self-management abilities and found statistical significance (P=0.017), indicating that individuals living alone with higher cognitive function report lower self-management abilities. CONCLUSION Cognitive impairment in COPD does not appear to be meaningfully associated with COPD severity, health outcomes, or self-management abilities. The routine screening for cognitive impairment due to a diagnosis of COPD may not be indicated. Living alone significantly affects the interaction between self-management abilities and cognitive function.

Abstract
BACKGROUND The chronic respiratory disease questionnaire (CRDQ) is designed to assess health-related quality of life (HRQOL) in chronic respiratory conditions, but its reliability, validity and responsiveness in individuals with mild to moderate non-cystic fibrosis (CF) bronchiectasis are unclear. OBJECTIVES This study aimed to determine measurement properties of the CRDQ in non-CF bronchiectasis. METHODS Participants with non-CF bronchiectasis involved in a randomised controlled trial of exercise training were recruited. Internal consistency was assessed using Cronbach's α. Over 8 weeks, reliability was evaluated using intra-class correlation coefficients and Bland-Altman analysis for measures of agreement. Convergent and divergent validity was assessed by correlations with the other HRQOL questionnaires and the Hospital Anxiety and Depression Scale (HADS). The responsiveness to exercise training was assessed using effect sizes and standardised response means. RESULTS Eighty-five participants were included (mean age ± SD, 64 ± 13 years). Internal consistency was adequate (>0.7) for all CRDQ domains and the total score. Test-retest reliability ranged from 0.69 to 0.85 for each CRDQ domain and was 0.82 for the total score. Dyspnoea (CRDQ) was related to St George's respiratory questionnaire (SGRQ) symptoms only (r = 0.38), with no relationship to the Leicester cough questionnaire (LCQ) or HADS. Moderate correlations were found between the total score of the CRDQ, the SGRQ (rs = -0.49) and the LCQ score (rs = 0.51). Lower CRDQ scores were associated with higher anxiety and depression (rs = -0.46 to -0.56). The responsiveness of the CRDQ was small (effect size 0.1-0.24). CONCLUSIONS The CRDQ is a valid and reliable measure of HRQOL in mild to moderate non-CF bronchiectasis, but responsiveness was limited.

Abstract
PURPOSE Lung cancer poses multiple challenges to adopting an exercise (EX) program, and the ideal timing of an EX program to improve quality of life (QoL) is unknown. This study explored the EX counselling and programming preferences of lung cancer survivors and examined the association of EX before diagnosis, during treatment and after treatment on QoL. METHODS Cross-sectional, retrospective survey design in a sample of lung cancer survivors. EX preferences were compared between patients who had received radical chest radiation or lung surgery versus those who had not. EX was measured by self-report using the Godin Leisure Time Exercise Questionnaire (GLTEQ). Separate linear regression models, controlling for significant covariates, examined the association of EX at each time point with scores on QoL measures and subscales. RESULTS Participants (N = 66, M age 66.4 ± 9.1) were between 4 months and 11.5 years after lung cancer diagnosis (M = 31.7 ± 22.9 months). Patients who had lung surgery were more likely to prefer to start an EX program during adjuvant treatment than those who did not have surgery (t(33) = 2.43, p = .025). Compared to prediagnosis EX (M = 36.7 ± 56.0 MET h/week), EX levels declined significantly during (M = 12.4 ± 25.0 MET h/week) and after (M = 12.3 ± 17.4 MET h/week) treatment (p < .05). After controlling for disease stage and income, regression models were not significant, but EX after treatment was a significant individual predictor of fatigue (β = .049, p = .006) and QoL measured by the Chronic Respiratory Disease Questionnaire (β = .163, p = .025). CONCLUSIONS Lung cancer patient preferences indicate that EX program timing should take into account whether the patient has undergone surgery. Lung cancer survivors' EX levels declined after diagnosis and engaging in EX after treatment may improve fatigue and QoL.

Abstract
BACKGROUND: Dyspnea is a distressing symptom experienced by people with chronic obstructive pulmonary disease (COPD). The dyspnea-12 (D-12) questionnaire comprises of 12 items and assesses the quality of this symptom, its severity and the emotional response. The original (English) version of the D-12 is reliable and valid for the measurement of dyspnea in pulmonary diseases. AIM: To translate the D-12 into Arabic and determine whether this version is reliable and valid in Saudi nationals with COPD. METHODS: The D-12 was translated into Arabic version and reviewed by an expert panel before being back-translated into English. The Arabic version was administered to five patients with COPD to test whether it was easily understood after which a final Arabic version was produced. Thereafter, 40 patients with COPD (aged 63 9 years; 33 [82.5%] males; forced expiratory volume in one second (FEV
1) 47 16% predicted) completed the D-12, the COPD Assessment Test (CAT) and the Chronic Respiratory Disease Questionnaire (CRDQ). Lung function and 6-minute walk distance were also measured. The D-12 was re-administered two weeks later. RESULTS: The Arabic version of the D-12 demonstrated good reliability over the two administration (intraclass correlation coefficient = 0.94, P = 0.01). Strong associations were demonstrated between the (1) total score for the D-12 and the CAT, (2) quality sub-score of the D-12 and the CAT and (3) emotional response sub-score of the D-12 and emotional function domain of the CRDQ (r ≥ 0.6, all P < 0.01). CONCLUSION: The Arabic version of the D-12 is a reliable and valid instrument in Saudi nationals with COPD.

Abstract
Background Although the endurance shuttle walk test (ESWT) has proven to be responsive to change in exercise capacity after pulmonary rehabilitation (PR) for COPD, the minimally important difference (MID) has not yet been established. We aimed to establish the MID of the ESWT in patients with severe COPD and chronic hypercapnic respiratory failure following PR. Methods Data were derived from a randomized controlled trial, investigating the value of noninvasive positive pressure ventilation added to PR. Fifty-five patients with stable COPD, GOLD stage IV, with chronic respiratory failure were included (mean (SD) FEV1 31.1 (12.0) % pred, age 62 (9) y). MID estimates of the ESWT in seconds, percentage and meters change were calculated with anchor based and distribution based methods. Six minute walking distance (6MWD), peak work rate on bicycle ergometry (Wpeak) and Chronic Respiratory Questionnaire (CRQ) were used as anchors and Cohen’s effect size was used as distribution based method. Results The estimated MID of the ESWT with the different anchors ranged from 186–199 s, 76–82% and 154–164 m. Using the distribution based method the MID was 144 s, 61% and 137 m. Conclusions Estimates of the MID for the ESWT after PR showed only small differences using different anchors in patients with COPD and chronic respiratory failure. Therefore we recommend using a range of 186–199 s, 76–82% or 154–164 m as MID of the ESWT in COPD patients with chronic respiratory failure. Further research in larger populations should elucidate whether this cut-off value is also valid in other COPD populations and with other interventions.

CAD SAUDE PUBLICA 2015; 30:1270-80. [PMID: 25099050 DOI: 10.1590/0102-311x00072313] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2013] [Accepted: 11/14/2013] [Indexed: 11/21/2022] Open
Abstract
This qualitative study explores the illness experiences, the efficacy of pulmonary rehabilitation as perceived by patients with chronic obstructive pulmonary disease (COPD) and their rationale for improvements in health. 23 patients participated in a daily, three-month home-based pulmonary rehabilitation. A pre-post self-perceived assessment of efficacy was conducted. Semi-structured interviews, illness narratives and participant-observation provided a "dense description" of patients' lived-experience before and after the program. Interviews and narratives were tape-recorded, transcribed and coded. Qualitative data was subjected to "thematic content analysis" and "contextualized semantic interpretation". Patients compare functional status before and after falling ill, experience loss, stigma and depression, describe health improvements and judge the pulmonary rehabilitation's efficacy. Giving voice to chronically-ill patients, as individuals, is needed. To reduce clinical conflicts, health professionals should encourage illness narratives and value their patients' lived-experience.

[PMID: 25134693 PMCID: PMC4141095 DOI: 10.1186/1472-6963-14-349] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Accepted: 08/14/2014] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Although the burden of cardiopulmonary diseases in the Aboriginal community is high, utilisation of rehabilitation services has been poor. We evaluated the uptake and effectiveness of a cardiovascular and pulmonary rehabilitation program specifically designed and provided for the Aboriginal community, by the Tasmanian Aboriginal Centre, for people with diagnosed chronic heart or respiratory disease and those at high risk of developing such conditions. METHODS Participants had established chronic obstructive pulmonary disease, ischaemic heart disease or chronic heart failure or were at high risk of developing such diseases because of multiple risk factors. Rehabilitation programs (n = 13) comprised two exercise and one education session per week over eight weeks. Data, collected at baseline and on completion, included health status, risk factors, attendance, anthropometric measurements, physical capacity and quality of life. Data from participants who attended at least one program session were analysed. Qualitative written feedback from participants and staff was analysed thematically. RESULTS Of 92 participants (39% with an established disease diagnosis), 72 provided follow-up data. Participants lost weight, and waist circumference decreased (mean -3.6 cm, 95% confidence interval (CI)-2.5 to -4.7). There were clinically significant improvements in six-minute walk distance (mean 55.7 m, 95% CI 37.8 to 73.7) and incremental shuttle walk (mean 106.2 m, 95% CI 79.1 to 133.2). There were clinically significant improvements in generic quality of life domains, dyspnoea and fatigue. Generally, the improvements in participants with established cardiac or respiratory diseases did not differ from that in people with risk factors. Analysis of qualitative data identified three factors that facilitated participation: support from peers and health workers, provision of transport and the program structure. Participants' awareness of improvements in their health contributed to ongoing participation and positive health outcomes, and participants would recommend the program to family and friends. CONCLUSION A cardiopulmonary program, which included exercise and education and met national guidelines, was designed and delivered specifically for the Aboriginal community. It increased participation in rehabilitation by Aborigines with, or at high risk of, established disease and led to positive changes in health behaviours, functional exercise capacity and health related quality of life.
