Abstract
Background Exacerbations of COPD (ECOPD) have a major impact on patients and healthcare systems across the world. Precise estimates of the global burden of ECOPD on mortality and hospital readmission are needed to inform policy makers and aid preventive strategies to mitigate this burden. The aims of the present study were to explore global in-hospital mortality, post-discharge mortality and hospital readmission rates after ECOPD-related hospitalisation using an individual patient data meta-analysis (IPDMA) design. Methods A systematic review was performed identifying studies that reported in-hospital mortality, post-discharge mortality and hospital readmission rates following ECOPD-related hospitalisation. Data analyses were conducted using a one-stage random-effects meta-analysis model. This study was conducted and reported in accordance with the PRISMA-IPD statement. Results Data of 65 945 individual patients with COPD were analysed. The pooled in-hospital mortality rate was 6.2%, pooled 30-, 90- and 365-day post-discharge mortality rates were 1.8%, 5.5% and 10.9%, respectively, and pooled 30-, 90- and 365-day hospital readmission rates were 7.1%, 12.6% and 32.1%, respectively, with noticeable variability between studies and countries. Strongest predictors of mortality and hospital readmission included noninvasive mechanical ventilation and a history of two or more ECOPD-related hospitalisations <12 months prior to the index event. Conclusions This IPDMA stresses the poor outcomes and high heterogeneity of ECOPD-related hospitalisation across the world. Whilst global standardisation of the management and follow-up of ECOPD-related hospitalisation should be at the heart of future implementation research, policy makers should focus on reimbursing evidence-based therapies that decrease (recurrent) ECOPD.

Shin HJ, Kim YI, Kim Y, Lee CY, Ra SW, Moon JY, Jung KS, Yoo KH, Shin KC, Lim SC. When is LABA/LAMA Better than LAMA in GOLD Group B or D Patients for Reducing Acute Exacerbations of COPD? Chonnam Med J 2023; 59:180-187. [PMID: 37840676 PMCID: PMC10570857 DOI: 10.4068/cmj.2023.59.3.180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 08/28/2023] [Accepted: 09/04/2023] [Indexed: 10/17/2023] Open
Abstract
Long-acting β2-agonist (LABA)/long-acting muscarinic-antagonist (LAMA) dual therapy has been found to be more effective than LAMA monotherapy in the treatment of chronic obstructive pulmonary disease (COPD). However, among patients with group B or D COPD, the characteristics of patients for whom LABA/LAMA dual therapy is superior to LAMA monotherapy in minimizing acute exacerbations remain unknown. With data from a prospective COPD cohort, subgroup analyses were conducted to determine whether LABA/LAMA dual therapy was superior to LAMA monotherapy in reducing the rate of acute exacerbations in group B and D COPD patients. Group B and D COPD patients taking LAMA or LABA/LAMA were enrolled according to the 2022 Global initiative for Chronic Obstructive Pulmonary Disease guidelines. A total of 737 patients were included in this study: 600 with group B COPD and 137 with group D COPD. Compared with patients taking LAMA monotherapy, those taking LABA/LAMA had a significantly lower incidence of acute exacerbations over 1 year. In the subgroup of patients ≥70 years old, there was a significantly lower risk of severe COPD exacerbations among group B patients taking LABA/LAMA than among those taking LAMA monotherapy (odds ratio [OR], 0.258; 95% confidence interval [CI], 0.095-0.703). In contrast, in the subgroup of group D patients with COPD Assessment Test scores ≥25, compared with LAMA monotherapy, LABA/LAMA treatment was associated with lower risk of severe COPD exacerbations (OR, 0.115; 95% CI, 0.018-0.749). The combination of LABA and LAMA was found to be superior to LAMA monotherapy, especially for treating older adults with group B COPD, as well as for group D patients with severe symptoms.

Abstract
PURPOSE Our study aimed to compare the predictive value of the COPD Assessment Test (CAT) score at baseline and short-term change in CAT for future exacerbations in chronic obstructive pulmonary disease (COPD) patients. METHODS This was a multicentre prospective study. Patients with COPD were recruited into the study and followed up for one year. CAT score and exacerbation in the previous year were collected at baseline. Change in CAT was defined as CAT score changing between baseline and the 6-month follow-up. Exacerbation was recorded during the one-year follow-up from 0th to 12th month. RESULT A total of 536 patients were enrolled for final analysis. The mean baseline CAT score was 14.5 ± 6.6 and the median (IQR) change in CAT was -2 (8). On Cox regression analysis, baseline CAT score, change in CAT and history of exacerbation were independent risk factors for exacerbation in the one-year follow-up. Compared with the r value of correlation between baseline CAT score and frequency of exacerbations during the one-year follow-up (r = 0.286, p < .001), that correlation between the change in CAT and frequency of exacerbations during follow-up was higher (r = 0.421, p < .001). The receiver operating characteristic (ROC) curves showed that change in CAT had a better predictive capacity for future exacerbation than baseline CAT (0.789 versus 0.609, p = .001). The ROC showed that change in CAT also had a better predictive capacity for future exacerbation than exacerbation in the previous year (0.789 versus 0.689, p = .011). CONCLUSION The correlation between baseline CAT score and future exacerbation was weak, however, the correlation between change in CAT and future exacerbation was moderate. Change in CAT in the short term had a better predictive value for future exacerbations of COPD than baseline CAT and exacerbation in the previous year.

Abstract
BACKGROUND In the InforMing the PAthway of COPD Treatment (IMPACT) trial, single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) reduced moderate/severe exacerbation rates versus FF/VI and UMEC/VI in patients with chronic obstructive pulmonary disease (COPD). This post hoc analysis tested the relationship between baseline health status, risk of future exacerbations, and efficacy outcomes. METHODS IMPACT was a Phase 3, double-blind, 52-week trial in patients with symptomatic COPD (COPD Assessment Test [CAT] score ≥10) and ≥1 moderate/severe exacerbation in the prior year randomized 2:2:1 to FF/UMEC/VI 100/62.5/25mcg, FF/VI 100/25mcg, or UMEC/VI 62.5/25mcg. Annual rate of on-treatment moderate/severe exacerbations, lung function, and safety were analyzed by continuous baseline CAT score. RESULTS Moderate/severe exacerbation rates increased with increasing baseline CAT scores in FF/UMEC/VI and UMEC/VI arms. There was a very small increase in on-treatment pneumonia rates at higher baseline CAT scores across all treatment arms. FF/UMEC/VI reduced moderate/severe exacerbation rates versus UMEC/VI (i.e., the inhaled corticosteroid effect) consistently across the range of CAT scores. The reduction with FF/UMEC/VI versus FF/VI (i.e., the long-acting muscarinic antagonist effect) was greatest at lower CAT scores and appeared lesser at higher CAT scores. Improvements in lung function were observed with FF/UMEC/VI versus FF/VI and UMEC/VI, regardless of baseline CAT score. CONCLUSIONS The CAT score was predictive of exacerbation risk. Worse baseline health status was associated with higher moderate/severe exacerbation and pneumonia rates. Irrespective of baseline CAT score, FF/UMEC/VI improved lung function, and reduced the annual moderate/severe exacerbation rates versus dual therapy. Results indicate an overall favorable benefit-risk profile of triple versus dual therapy, irrespective of CAT score. Clinical Trial Registration:GSK (CTT116855/NCT02164513).

Abstract
Background We developed the chronic obstructive pulmonary disease (COPD)-Lower Respiratory Tract Infection-Visual Analogue Score (c-LRTI-VAS) in order to easily quantify symptoms during exacerbations in patients with COPD. This study aimed to validate this score. Methods In our study, patients with stable COPD as well as those with an acute exacerbations of COPD (AECOPD) were included. The results of c-LRTI-VAS were compared with other markers of disease activity (lung function parameters, oxygen saturation and two health related quality of life questionnaires (St Georges Respiratory Questionnaire (SGRQ) and Clinical COPD Questionnaire (CCQ)) and validity, reliability and responsiveness were assessed. Results Eighty-eight patients with clinically stable COPD and 102 patients who had an AECOPD completed the c-LRTI-VAS questionnaire. When testing on two separate occasions for repeatability, no statistically significant difference between total scores was found 0.143 (SD 5.42) (p=0.826). Internal consistency was high across items (Cronbach’s apha 0.755). Correlation with SGRQ and CCQ total scores was moderate to high. After treatment for hospitalised AECOPD, the mean c-LRTI-VAS total score improved 8.14 points (SD 9.13; p≤0.001). Conclusions c-LRTI-VAS showed proper validity, responsiveness to change and moderate to high correlation with other questionnaires. It, therefore, appears a reliable tool for symptom measurement during AECOPD. Trial registration number NCT01232140.

Clinical and spirometric variables are better predictors of COPD exacerbations than routine blood biomarkers. Respir Med 2020; 171:106091. [PMID: 32829181 DOI: 10.1016/j.rmed.2020.106091] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 07/14/2020] [Accepted: 07/20/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Understanding the risk factors for exacerbations of COPD may help provide a more personalised approach to exacerbation prevention. METHOD Observational, prospective, international, multicentre study aimed at identifying risk factors for exacerbations of COPD. Clinical variables, lung function and CAT scores were collected at baseline. In addition, routine blood biomarkers were also obtained, and patients were followed for 12 months. RESULTS A total of 326 patients were included. Of these, 155 (47.5%) presented at least one exacerbation. The median time to the first exacerbation was 147 days. Exacerbators had more respiratory symptoms, more impairment in FEV1(%), FVC(%) and a worse CAT score. Regarding biomarkers, only C-reactive protein was significantly higher in exacerbators (2.8 (standard deviation (SD):3.8) mg/dL vs. 1.9 (SD:2.6) mg/dL; p = 0.037). In multivariate analysis, only CAT scores, FEV1(%) and previous exacerbations were significantly associated with having an exacerbation during follow-up. In the equation of risk, patients with a CAT score ≥15, FEV1(%) <55% and at least one exacerbation the previous year had a probability of 76% of having an exacerbation during the next year, compared with 17% in patients who had none of the previous variables. No biomarkers showed a significant association in multivariate analysis. CONCLUSIONS Less than half of the patients presented an exacerbation during the one-year follow-up. CAT scores, FEV1(%) and previous exacerbations were the only variables associated with increased risk of exacerbations. Routine biomarkers did not provide additional information to evaluate the risk of exacerbations.

Respiration 2020; 99:606-616. [PMID: 32659763 DOI: 10.1159/000507097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Accepted: 03/06/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The Clinical COPD Questionnaire (CCQ) has been suggested by the Global Initiative of Chronic Obstructive Lung Disease (GOLD) as a comprehensive symptom measurement tool, which helps to classify patients in order to direct pharmacological treatment. Therefore, it is essential to understand its determinants. OBJECTIVES To identify the determinants of the overall CCQ score and scores of its 3 subdomains among chronic obstructive pulmonary disease (COPD) patients from China. METHODS A total of 1,241 COPD patients in the outpatient department of the Second Xiangya Hospital in China were recruited. Basic information and clinical data were collected. Differences in the GOLD categories based on Modified Medical Research Council Dyspnea Scale (mMRC), COPD Assessment Test (CAT), and CCQ were compared. Multiple linear regression analyses were performed to evaluate determinant factors of the total CCQ and subdomain scores. RESULTS The total CCQ and/or separate domain scores significantly differed with sex, age, BMI, smoking status, biomass fuel exposure, exacerbation frequency, mMRC, CAT, and GOLD grades and groups. Subjects with asthma-COPD overlap (ACO) had worse health status based on CCQ than those with COPD alone. As for the 16 subgroups based on GOLD 2017, statistical differences in the total CCQ and functional domain scores were found among subgroups 1A-4A, 1B-4B, and 1D-4D. The mMRC classified much more patients into more symptom groups than CAT and CCQ. No significant difference was observed in the GOLD categories between the CAT and CCQ (cut point = 1.5). Multiple linear regression analysis showed that smoking status, underweight, ACO, post-bronchodilator FEV1% predicted <50%, exacerbation history, and mMRC were independently associated with the total CCQ score. Only 3 variables were significantly associated with the symptom domain: ACO, exacerbations, and mMRC; for the functional domain, age ≥75 years, ACO, post-bronchodilator FEV1% predicted <50%, exacerbation history, and mMRC were significant; female sex, underweight, frequent exacerbations (≥2), and mMRC were significantly associated with higher scores in the mental domain. CONCLUSIONS The classification of COPD produced by mMRC, CAT, and CCQ was not identical. Smoking status, underweight, ACO, post-bronchodilator FEV1% predicted <50%, exacerbation history, and mMRC were associated with lower health-related quality of life assessed by the total CCQ score, while different subdomains of CCQ had different determinant factors.

Abstract
BACKGROUND The COPD Assessment Test (CAT) has been proposed to help guide therapy in chronic obstructive pulmonary disease (COPD). It is important to understand the distribution of scores in different COPD populations and their determinants. METHODS The POPE study is an international, observational cross-sectional study of COPD subjects in 11 Central and Eastern European countries aimed at characterizing COPD phenotypes. Here we report the analysis of CAT scores with the objective of identifying their determinants, evaluating symptom load and investigating the distribution of scores among the participating countries. Additionally, we investigated the discrepancies between the CAT and modified Medical Research Council (mMRC) scores when used to classify patients according to the GOLD strategy. RESULTS The study included 3452 patients (69.2% men, mean forced expiratory volume in 1 s (FEV1% predicted) 52.5%). The mean CAT score was 17.5 (SD = 7.8), ranging from 15.1 in Hungary to 21.2 in Bulgaria. Multiple linear regression analysis showed six variables significantly associated with CAT scores: depression, number of previous exacerbations, 6-min walking distance, FEV1(%), mMRC and country and explained 47.2% of the variance of CAT. According to either CAT or mMRC, up to 23.9% patients would be classified in different GOLD groups. CONCLUSIONS The CAT score may be predicted by factors related to COPD severity, depression and exercise capacity, with significant differences in the distribution of CAT scores in different countries. According to our results CAT >10 is not equivalent to mMRC >2 for assessing symptom burden. TRIAL REGISTRATION ClinicalTrials.gov, identifier NCT02119494.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) exacerbations can accelerate disease progression and lead to higher health care costs. To improve patient survival and reduce cost, risk assessment measures should be developed to identify patients at risk for exacerbations and prevent future exacerbations. OBJECTIVES To (a) externally validate the COPD treatment ratio (CTR) as a measure of COPD exacerbation risk based on predictive models previously tested and (b) assess the measure's capability to assess risk using only pharmacy claims for use in Medicare Part D programs. METHODS This was a retrospective observational study conducted using the Humana research datasets. Separate assessments were performed using pharmacy-only models that excluded risk factors derived from medical claims. Patients were aged ≥ 40 years, with ≥ 1 inpatient hospitalization or ≥ 2 physician's office, emergency department, or urgent care visits with a COPD diagnosis. Using logistic regression models, risk factors (age, exacerbation history, COPD and concomitant medication use, and comorbidities) were assessed during the baseline period (year 1) and were used to predict the risk of exacerbation during year 2. Continuous and dichotomized CTRs were analyzed. A cut-point of 0.3 was initially used for dichotomizing CTR, and subsequently receiver operating characteristics (ROC) analysis was used to determine the optimal cut-point for CTR. RESULTS A total of 92,496 patients were identified, the majority of which (96.2%) were Medicare members with a mean age of 69 years. During the baseline period, 14.0% and 11.2% of patients had ≥ 1 moderate or severe exacerbation, respectively. Overall, the CTR performed well in predicting future COPD exacerbations, especially severe exacerbations. ROC analysis suggested that 0.7 was the optimal cut-point for dichotomizing CTR. Patients with a CTR ≥ 0.7 had a 7.9% (OR = 0.921; 95% CI = 0.852-0.995) lower risk of a severe exacerbation, compared with those with a CTR < 0.7. Stronger effects were seen in pharmacy-only models, with patients 17% less likely to experience a severe exacerbation with a CTR ≥ 0.7 compared with patients with a CTR < 0.7. CONCLUSIONS This study validated the use of CTR as a modifiable measure of risk of COPD exacerbation in a large commercial and Medicare population and remained a robust predictor when pharmacy-only claims data were available. A CTR of ≥ 0.7 may be a useful target to help reduce the risk of severe exacerbations, and its use by payer or quality organizations has the potential to improve COPD management. DISCLOSURES This study was funded by GlaxoSmithKline (GSK; study number HO-15-16651). GSK had a role in the study design, collection, analysis, and interpretation of data and in the writing of the study report but did not place any restrictions on access to the data or on the statements made in the manuscript.

Abstract
Background Disease control is an important objective of COPD management. The SINCON study evaluated the level of control in terms of respiratory symptoms and exacerbations in Spanish patients with COPD for ≥2 years. Methods SINCON was a descriptive, cross-sectional, multicenter study that assessed degree of control using a combined index comprising COPD assessment test (CAT), modified Medical Research Council dyspnea scale (mMRC), and number of moderate/severe exacerbations in the last year. Based on this score, patients were categorized as “well controlled” or “poorly controlled”. Degree of control was also assessed relative to patient phenotype, setting (primary care [PC] vs respiratory care [RC]), and impact of treatment on morning symptoms. Results Of the 481 patients (PC: 307, RC: 174) analyzed, COPD was poorly controlled in 63.2%. Some differences were found between clinical settings: PC patients were more poorly controlled (PC: 66.4% vs RC: 57.5%; P = 0.06) and had higher CAT score (PC: 17.9 vs RC: 15.5; P < 0.05), and higher rate of moderate/severe exacerbations during previous year (PC: 1.5 vs RC: 1.1; P < 0.05), while dyspnea degree was similar in both settings. Regarding phenotypes, non-exacerbators demonstrated better control vs exacerbators. Morning symptoms score improved between waking and 3 h after bronchodilator treatment (P < 0.05), with greater improvements in PC patients (PC: − 6.5 vs RC: − 5.0 points; P < 0.05). Conclusions Most COPD patients were poorly controlled with some differences observed between PC and RC settings and between patient phenotypes. Our index may be easily used in PC settings to optimize COPD treatment.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) impacts health-related quality of life in men more than in women. In patients with dyspnea, frailty is more likely to develop and aggravate disability. Despite this, few studies have addressed frailty in men with COPD. The present study investigated the effects of dyspnea and its related factors on frailty in men with COPD. Patients and methods This cross-sectional observational study selected 125 participants by voluntary sampling at the thoracic outpatient clinics of two medical centers in Taiwan. The modified Medical Research Council questionnaire was used as the basis to classify dyspnea. Data were collected using questionnaires and analyzed using IBM SPSS Statistics for Windows, version 24.0 (IBM Corporation., Armonk, NY, USA). Results There were 85.90% and 26.70% patients with COPD assessed in the unfit stage among the dyspnea and non-dyspnea groups, respectively. Additionally, the number of medication use and the COPD Assessment Test (CAT) scores were correlated with the period from fitness to unfitness among the dyspnea group and non-dyspnea group. Conclusion COPD with dyspnea was more common in the unfit stages. The total number of medication use and CAT scores were significantly related to frailty.

Abstract
Background Both the COPD Assessment Test (CAT) and the Clinical COPD Questionnaire (CCQ) were recommended as comprehensive symptom measures by the Global Initiative for Chronic Obstructive Lung disease. The main objective of this work was to compare the evaluation of symptom severity with the CAT and the CCQ and find a cutoff value of the CCQ for the Chinese clinical population. Methods Patients diagnosed with stable COPD in the outpatient department who completed the CAT and CCQ were enrolled from November 2015 to December 2016. Scores of 0-10, 11-20, 21-30, and 31-40 represent low, medium, high, and very high impact level, respectively, by CAT. Scores of the CCQ can be considered as acceptable (CCQ<1), acceptable for moderate disease (1≤CCQ<2), instable-severe limited (2≤CCQ<3), and very instable-very severe limited (CCQ≥3). Results According to the CAT, only 20.4% of patients belonged to the high (21≤CAT≤30) and very high (31≤CAT≤40) impact levels, which were statistically lower than those of the CCQ, which classified over half of the population (51.1%) into the instable-severe limited (2≤CCQ<3) and very instable-very severe limited (CCQ≥3) categories (P<0.001). The kappa of agreement for the symptom groups by CAT and CCQ (cutoff point 1.5) was 0.495, but only slight agreement (0.144) was found between the CAT and CCQ with the cutoff point of 1.0. The CAT and the total CCQ had a strong correlation (rho=0.776, P<0.01). The CCQ 1.0 and 1.5 corresponded to CAT 4.2 and 9.7, respectively. The CAT 10.0 was equivalent to 1.53 of the CCQ. In addition, with higher scores of the CAT and CCQ, subjects displayed more impairment in lung function, higher levels on modified Medical Research Council, and higher exacerbation rates in the last year (P<0.001). Similarly, patients with more exacerbations presented worse scores on the CAT and total CCQ as well as its 3 domains (P<0.001). Conclusion Compared with the CAT, the CCQ was more likely to classify the patients into more severe categories, and 1.5 might be a better cutoff point for the CCQ than 1.0. Both the CAT and the overall CCQ with its 3 domains were able to discriminate between groups of patients that differ in COPD severity.

Abstract
Background COPD assessment test (CAT) is a short, easy-to-complete health status tool that has been incorporated into the multidimensional assessment of COPD in order to guide therapy; therefore, it is important to understand the factors determining CAT scores. Methods This is a post hoc analysis of a cross-sectional, observational study conducted in respiratory medicine departments and primary care centers in Spain with the aim of identifying the factors determining CAT scores, focusing particularly on the cognitive status measured by the Mini-Mental State Examination (MMSE) and levels of depression measured by the short Beck Depression Inventory (BDI). Results A total of 684 COPD patients were analyzed; 84.1% were men, the mean age of patients was 68.7 years, and the mean forced expiratory volume in 1 second (%) was 55.1%. Mean CAT score was 21.8. CAT scores correlated with the MMSE score (Pearson's coefficient r=-0.371) and the BDI (r=0.620), both p<0.001. In the multivariate analysis, the usual COPD severity variables (age, dyspnea, lung function, and comorbidity) together with MMSE and BDI scores were significantly associated with CAT scores and explained 45% of the variability. However, a model including only MMSE and BDI scores explained up to 40% and BDI alone explained 38% of the CAT variance. Conclusion CAT scores are associated with clinical variables of severity of COPD. However, cognitive status and, in particular, the level of depression explain a larger percentage of the variance in the CAT scores than the usual COPD clinical severity variables.

Abstract
BACKGROUND No specific (only subgroup) recommendations for the use of long-acting muscarinic antagonists in chronic obstructive pulmonary disease (COPD) exist. The aim of this exploratory hypothesis generating study was to assess whether different phenotypic/endotypic characteristics could be determinants of the short-term ineffectiveness of the initial tiotropium bromide monotherapy in treatment naïve moderate to severe COPD patients. METHODS A total of 51 consecutively recruited COPD patients were followed for 3 months after the initial evaluation and prescribed initial treatment (tiotropium). Short-term treatment ineffectiveness was assessed as a composite measure comprising COPD exacerbations, need for additional treatment, and no improvement in functional parameters, e.g. 6‑min walking test (6MWT), body-mass index, airflow obstruction, dyspnea, and exercise (BODE) index and forced expiratory volume in 1 s (FEV1), and as single components. RESULTS Treatment ineffectiveness was significantly associated with baseline hemoglobin level, COPD assessment test (CAT) score, modified Medical Research Council (mMRC) scale and BODE index (p = 0.002). Incident exacerbation during the follow-up was associated with baseline bronchoalveolar lavage fluid (BALF) alpha-amylase level and CAT score (p < 0.001), and change in treatment with leukocyte count, 6MWT desaturation and fatigue (p < 0.001). No improvement in 6MWT was associated with baseline CAT score, body mass index, mMRC, fatigue, 6MWT and BODE index (p = 0.002). No improvement in BODE index was associated with leukocyte count, serum interleukin 8 (IL-8) and BALF albumin levels (p < 0.001); and no improvement in FEV1 with CAT score, baseline vital capacity and BALF tumor necrosis factor alpha (TNF-alpha) level (p < 0.001). CONCLUSION Our results suggest that there is a possibility to identify predictors of short-term tiotropium ineffectiveness in patients with moderate to severe COPD.

Abstract
The Clinical COPD Questionnaire (CCQ) is recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) to evaluate health status in patients with COPD. The objective of this work was to systemically assess the reliability, validity, responsiveness and minimum clinically important difference (MCID) of the CCQ. A structured search was conducted in three databases to identify articles that evaluated the psychometric properties of the CCQ in individuals with COPD. Two investigators screened the title, abstract and full text of the articles to determine study eligibility and performed the data extraction. Quality assessment of included studies was assessed by the COSMIN (Consensus-Based Standards for the Selection of Health Measurement Instruments) checklist. Finally, 43 studies were included, over half of which had fair methodological quality. Internal consistency (reliability) of the CCQ total score ranged from 0.84 to 0.94, and test-retest reliability was 0.70-0.99. The overall CCQ had a better correlation with St George's Respiratory Questionnaire (SGRQ; from 0.71 to 0.88) and COPD Assessment Test (CAT; from 0.64 to 0.88) than modified Medical Research Council (mMRC; from 0.392 to 0.668) and forced expiratory volume in 1 s (FEV1 % predicted; from -0.31 to -0.68). Scores were different within GOLD stages, groups, composite events and co-morbidities. CCQ was sensitive to exacerbations, pulmonary rehabilitation and smoking cessation with the MCID of 0.4. The CCQ is a very useful and practical tool that can be used in clinical populations with good reliability, validity and responsiveness to interventions.

Abstract
Severe exacerbations of COPD, ie, those leading to hospitalization, have profound clinical implications for patients and significant economic consequences for society. The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system. This review identified risk factors that contribute to the development of severe exacerbations, treatment options (bronchodilators, antibiotics, corticosteroids [CSs], oxygen therapy, and ventilator support) to manage severe exacerbations, and strategies to prevent readmission to hospital. Risk factors that are amenable to change have been highlighted. A number of bronchodilators have demonstrated successful reduction in risk of severe exacerbations, including long-acting muscarinic antagonist or long-acting β2-agonist mono- or combination therapies, in addition to vaccination, mucolytic and antibiotic therapy, and nonpharmacological interventions, such as pulmonary rehabilitation. Recognition of the importance of severe exacerbations is an essential step in improving outcomes for patients with COPD. Evidence-based approaches to prevent and manage severe exacerbations should be implemented as part of targeted strategies for disease management.

Abstract
Purpose Chronic bronchitis (CB), emphysematous (EM) and asthma–chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) phenotypes in COPD are well recognized. This study aimed to investigate distinguishing characteristics of these phenotypes in COPD patients with frequent exacerbations (FE). Patients and methods A retrospective study was carried out. COPD patients with acute exacerbations were consecutively reviewed from November 2015 to October 2016. Patients were divided into FE and infrequent exacerbations (iFE) subgroups. Results A total of 142 eligible COPD subjects were reviewed. In the CB phenotype subgroup, age, body mass index, forced expiratory volume in 1 second (FEV1) % predicted, COPD assessment test (CAT), modified Medical Research Council breathlessness measurement (mMRC) dyspnea scale, emphysema scores and arterial carbon dioxide pressure (PaCO2) were significantly different in subjects with FE when compared to those in subjects with iFE of CB. In the EM phenotype subgroup, age, CAT, mMRC scores and history of COPD were different in subjects with FE when compared to those in CB subjects with iFE. Multivariate analysis indicated that FEV1% predicted (odds ratio [OR] =0.90, P=0.04) and PaCO2 (OR =1.22, P=0.02) were independent risk factors for FE in COPD with CB phenotype, and CAT (OR =2.601, P=0.001) was the independent risk factor for FE in COPD with EM phenotype. No significant differences in characteristics were observed in ACOS phenotype subgroups with FE or iFE. Conclusion In CB or EM phenotypes, COPD patients with FE present several differential clinical characteristics compared to patients with iFE, while the characteristics of ACOS phenotype in patients with FE need more investigation.

Abstract
AIM To develop and do an initial validation of a new simple tool (self-administered questionnaire) that would be sensitive and specific enough to detect early changes in smokers leading to future development of chronic obstructive pulmonary disease (COPD). METHODS 224 consecutive participants (50.9% women), with mean±standard deviation age of 52.3±6.7 years, 37.5±16.7 pack-years smoking history (85.8% active smokers), and no prior diagnosis of COPD were recruited. The MARKO questionnaire was self-administered twice; at the general practitioner's office and after 2-4 weeks at the tertiary care hospital. Participants were assessed for COPD by a pulmonologist after filling in a quality of life (QoL) questionnaires, history-taking, physical examination, lung function test, 6-minute walk test, and laboratory tests. They were divided into four subgroups: "healthy" smokers, symptomatic smokers, and smokers with mild and moderately severe COPD. RESULTS Psychometric analyses indicated that the 18-item questionnaire had a very good internal consistency (Cronbach's alpha=0.91) and test-retest reliability for a four week period (c=0.89, 95% confidence interval [CI] 0.85-0.92, Lin's concordance). A significant correlations of MARKO scores were found with two QoL questionnaires; r=0.69 (P<0.001) and r=0.81 (P<0.001). Receiver operating characteristic curve analysis showed an area under the curve of 0.753 (95% CI 0.691-0.808, <0.001), with a sensitivity of 71.83% and specificity of 64.24% to discriminate "healthy" smokers from other subgroups. CONCLUSION Based on psychometric analyses and high convergent validity correlation with already validated QoL questionnaires, the newly developed MARKO questionnaire was shown to be a reliable self-administered short health status assessment tool.

Abstract
Background Early diagnosis of COPD is often not achieved due to limited recognition and limited access to the pulmonary function test. Our hypothesis was that lung function decline may be different between populations with mild COPD and those who are at high risk and do not receive treatment. Patients and methods Subjects with mild COPD and those from a high-risk COPD population were recruited from a community-based COPD epidemiological study after obtaining consent. Baseline clinical characteristics, symptom questionnaire, spirometry, low-dose computed tomography (LDCT) chest scan, and blood plasma biomarker data were collected initially and then 1 year later. Results A total of 617 participants were recruited, and 438 eventually completed the first-year follow-up visit; 72 participants (46 males) were in the mild COPD group, and 225 participants (165 males) were in the high-risk group. The mean forced expiratory volume in the first second of expiration (FEV1) decline in the mild COPD group was 129 mL, which was significantly higher than the 30 mL decline in the high-risk population group (P=0.005). Group category (odds ratio [OR] =0.230) and COPD Assessment Test (CAT) score (OR =9.912) were independent risk factors for an FEV1% predicted decline of >15% for all participants. In the mild COPD group, patients with a higher CAT (OR =5.310) and Emphysema Index (OR =5.681) were associated with a FEV1% predicted decline of >15% at the first-year follow-up. No factor showed a significantly predictive effect on FEV1 decline in the high-risk COPD group. Conclusion Group category was an independent influential factor associated with FEV1 decline.

Health Status of Patients with Moderate to Severe COPD after Treatment with Nebulized Arformoterol Tartrate or Placebo for 1 Year. Clin Ther 2016; 39:66-74.

Abstract
PURPOSE Chronic obstructive pulmonary disease (COPD) is a progressive disease that impairs both objectively measured lung function and patient-reported health status. In a randomized clinical trial of patients with moderate to severe COPD, we compared changes in health status after adding arformoterol tartrate or placebo to patients' treatment regimens. METHODS In this multicenter, double-blind trial, patients were randomized to receive nebulized arformoterol 15 µg BID (n = 420) or matched placebo (n = 421). Treatment with other COPD medications was permitted, except for long-acting β2-agonists. Inclusion criteria were a forced expiratory volume in 1 second (FEV1) ≤65% of predicted, FEV1 >0.50 L, age ≥40 years, smoking history ≥15 pack-years, and a baseline breathlessness severity grade ≥2. The Clinical COPD Questionnaire (CCQ) was used to measure health status at randomization and at months 3, 6, and 12. CCQ scores range from 0 to 6, with higher scores indicating worse health status, and a decrease from baseline in total score by 0.4 point is considered clinically significant. Outcomes were analyzed by using mixed models for repeated measures. FINDINGS At baseline, patients' mean age was 63.8 years; 42.9% of patients were female, and 51.4% were current smokers. The mean baseline CCQ total scores were 2.88 and 2.91 for the arformoterol and placebo groups, respectively. A total of 841 patients were randomized to receive either arformoterol (n = 420) or placebo (n = 421); among them, 211 (50.1%) who received placebo and 255 (60.7%) who received arformoterol completed the trial. Arformoterol-treated patients had greater mean improvement from baseline in CCQ total score (-0.18 vs 0.02; P = 0.001), symptoms (-0.21 vs 0.01; P = 0.002), functional state (-0.15 vs 0.02; P = 0.018), and mental state (-0.18 vs 0.02; P = 0.023) than patients receiving placebo. At study end, 38.3% of the arformoterol-treated patients and 30.8% of patients receiving placebo reported clinically significant improvements on the CCQ (P = 0.026). These improvements were only modestly correlated with improvements in FEV1 (r = -0.15; P < 0.01). IMPLICATIONS In this 52-week trial, arformoterol-treated patients had greater improvements in health status than patients receiving placebo. Assessing health status along with lung function seems to provide additional information regarding the effectiveness of COPD maintenance treatments. ClinicalTrials.gov identifier: NCT00909779.

Abstract
The aim of this study was to identify a multivariate model to predict poor outcomes after admission for exacerbation of chronic obstructive pulmonary disease (COPD). We performed a multicenter, observational, prospective study. Patients admitted to hospital for COPD were followed up for 3 months. Relevant clinical variables at admission were selected. For each variable, the best cut-offs for the risk of poor outcome were identified using receiver operating characteristic (ROC) curves. Finally, a stepwise logistic regression model was performed. A total of 106 patients with a mean age of 71.1 (9.8) years were included. The mean maximum expiratory volume in the first second (FEV1)(%) was 45.2%, and the mean COPD assessment test (CAT) score at admission was 24.8 (7.1). At 3 months, 39 (36.8%) patients demonstrated poor outcomes: death (2.8%), readmission (20.8%) or new exacerbation (13.2%). Variables included in the logistic model were: previous hospital admission, FEV1 < 45%, Charlson ≥ 3, hemoglobin (Hb)<13 g/L, PCO2 ≥ 46 mmHg, fibrinogen ≥ 554 g/L, C-reactive protein (CRP)≥45 mg/L, leukocyte count < 9810 × 109/L, purulent sputum, long-term oxygen therapy (LTOT) and CAT ≥ 31 at admission. The final model showed that Hb < 13 g/L (OR = 2.46, 95%CI 1.09-6.36), CRP ≥ 45 mg/L (OR = 2.91, 95%CI: 1.11-7.49) and LTOT (3.07, 95%CI: 1.07-8.82) increased the probability of poor outcome up to 82.4%. Adding a CAT ≥ 31 at admission increased the probability to 91.6% (AUC = 0.75; p = 0.001). Up to 36.8% of COPD patients had a poor outcome within 3 months after hospital discharge, with low hemoglobin and high CRP levels being the risk factors for poor outcome. A high CAT at admission increased the predictive value of the model.

Abstract
Background Chronic obstructive pulmonary disease (COPD) patients often present considerable individual medical burden in their symptoms, limitations, and well-being that complicate medical treatment. To improve their overall health status, while reducing the number of exacerbations, a multidisciplinary approach including different elements of care is needed. The aim of this study was to evaluate the effects of a remote support program on COPD patients at high risk of experiencing worsening of their disease and other health-related outcomes. Methods An observational, multicenter, prospective study aimed at evaluating the impact of a 7-month remote support program on COPD patients in exacerbations control and changes in health status measured with the COPD assessment test (CAT). Factors associated with a clinically relevant decrease in CAT were assessed using a logistic regression analysis. Results A total of 114 subjects started the program. The majority of the study population were males (81.6 %), retired (70.2 %), without academic qualifications or with a low level of education (68.4 %), and ex-smokers (79.8 %). The mean ± SD age was 69.6 ± 9.1 years and the BMI was 27.8 ± 5.5 Kg/m2. Overall, 41.9 % (95 % CI 31.9–52.0) patients, significantly improved health status (CAT decrease ≥ 2 points). Univariate analysis showed that significant improvement in CAT was associated with baseline CAT scores [high CAT score 19.2 (±7.5) vs. low CAT score 12.4 (±6.4); OR = 1.15, 95 % CI: 1.07–1.24; p < 0.001] and with being non-compliant [62.5 % (15/24) of non-compliant vs 34.7 % (24/69) of compliant patients significantly improved CAT scores; OR = 3.13, 95 % CI: 1.19–8.19; p = 0.021). After controlling for the effect of all variables in a multivariable logistic regression model, the only factor that remained significant was baseline CAT score. The proportion of smokers in the total population remained constant during the study. There was a significant reduction in the number of exacerbations after entering this remote support program with median -1 (IQR: -2, 0), (p < 0.001). The Morisky-Green questionnaire showed an increase of treatment compliance, namely at baseline, 25.8 % (24/93) of patients were noncompliant while in the end 66.7 % (16/24) of them became compliant) (p = 0.053). Conclusions A remote support program for high-risk COPD patients results in an improvement of the patients’ health status, particularly in those with initially poor health status, and it helps to reduce COPD exacerbations.
