Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is the third most common cause of death around the world. The affected patients suffer not only from impaired lung function, but also from a wide variety of comorbidities. Their cardiac comorbidities, in particular, lead to increased mortality. METHODS This review is based on pertinent publications retrieved by a selective search in PubMed, including guidelines from Germany and abroad. RESULTS The usual diagnostic criteria for COPD are a post-bronchodilator FEV1/FVC quotient below the fixed threshold of 0.7, or, preferably, below the lower limit of normal (LLN) according to the GLI reference values for the avoidance of over- and underdiagnosis. The overall prognosis is markedly affected by comorbidities of the lung itself and those that involve other organs; in particular, many persons with COPD die of heart disease. The potential presence of heart disease must be borne in mind in the evaluation of patients with COPD, as lung disease can impair the detection of heart disease. CONCLUSION As patients with COPD are often multimorbid, the early diagnosis and adequate treatment not only of their lung disease, but also of their extrapulmonary comorbidities are very important. Well-established diagnostic instruments and well-tested treatments are available and are described in detail in the guidelines concerning the comorbidities. Preliminary observations suggest that more attention should be paid to the potential positive effects of treating comorbidities on the lung disease itself, and vice versa.

Using a person-centered approach in clinical care for patients with complex chronic conditions: Perspectives from healthcare professionals caring for Veterans with COPD in the U.S. Veterans Health Administration's Whole Health System of Care. PLoS One 2023; 18:e0286326. [PMID: 37352241 PMCID: PMC10289382 DOI: 10.1371/journal.pone.0286326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 05/13/2023] [Indexed: 06/25/2023] Open
Abstract
BACKGROUND The largest nationally integrated health system in the United States, the Veterans Health Administration (VHA), has been undergoing a transformation toward a Whole Health (WH) System of Care. WH Clinical Care, a component of this system, includes holistically assessing the Veteran's life context, identifying what really matters to the Veteran, collaboratively setting and monitoring personal health and well-being goals, and equipping the Veteran with access to conventional and complementary and integrative health resources. Implementation of WH Clinical Care has been challenging. Understanding healthcare professionals' perspectives on the value of and barriers and facilitators to practicing WH Clinical Care holds relevance for not only VHA's efforts but also other health systems, in the U.S. and internationally, that are engaged in person-centered care implementation. OBJECTIVES We sought to understand perspectives of healthcare professionals at VHA on providing WH Clinical Care to Veterans with COPD, as a lens to understand the broader issue of WH Clinical Care for Veterans living with complex chronic conditions. DESIGN We interviewed 25 healthcare professionals across disciplines and services at a VA Medical Center in 2020-2021, including primary care providers, pulmonologists, palliative care providers, and chaplains. Interview transcripts were analyzed using qualitative content analysis. KEY RESULTS Each element of WH Clinical Care raised complex questions and/or concerns, including: (1) the appropriate depth/breadth of inquiry in person-centered assessment; (2) the rationale for elicitation of what really matters; (3) the feasibility and appropriate division of labor in personal health goal setting and planning; and (4) challenges related to referring Veterans to a broad spectrum of supportive services. CONCLUSIONS Efforts to promote person-centered care must account for healthcare professionals' existing comfort with its elements, advocate for a team-based approach, and continue to grapple with the conflicting structural conditions and organizational imperatives.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16986. [PMID: 36554866 PMCID: PMC9779594 DOI: 10.3390/ijerph192416986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/09/2022] [Accepted: 12/14/2022] [Indexed: 06/17/2023]
Abstract
Global policy documents for the promotion of physical activity (PA) play an important role in the measurement, evaluation, and monitoring of population PA levels. The World Health Organisation (WHO) guidelines include, for the first time, recommendations for specific populations, including individuals living with a range of non-communicable diseases. Of note, is the absence of any chronic respiratory diseases (CRDs) within the recommendations. Globally, CRDs are highly prevalent, are attributable to significant individual and societal burdens, and are characterised by low PA. As a community, there is a need to come together to understand how to increase CRD representation within global PA policy documents, including where the evidence gaps are and how we can align with PA research in other contexts. In this commentary, the potential for synergy between evidence into the relationships between PA in CRDs globally and the relevance to current policies, guidelines and action plans on population levels of PA are discussed. Furthermore, actions and considerations for future research, including the need to harmonize and promote PA assessment (particularly in low- and middle-income countries) and encompass the synergistic influences of PA, sedentary behaviour and sleep on health outcomes in CRD populations are presented.

Int J Chron Obstruct Pulmon Dis 2022; 17:2175-2185. [PMID: 36106158 PMCID: PMC9467295 DOI: 10.2147/copd.s369161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Accepted: 08/16/2022] [Indexed: 11/25/2022] Open
Abstract
Background Chronic Obstructive Pulmonary Disease (COPD) has been a concern all over the world because of its high prevalence and mortality. The ratio of low-density-lipoprotein to lymphocyte (LLR) has been widely used to predict the prognosis of cerebral infarction, but its association with COPD is less known. We aim to explore the relationship between LLR and COPD and to investigate its indicative role in the severity and prognosis of COPD. Methods In this study, 279 participants (n = 138 with COPD and n = 138 age- and sex-matched health control) were recruited. COPD patients were divided into two groups according to the optimal cut-off value of LLR determined by the receiver operating characteristic curve (ROC). We collected the clinical characteristics, pulmonary function, LLR, neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR) and other data of all subjects. t-test, Pearson correlation test, logistic regression analysis and other statistical analysis were carried out. Results Compared with the healthy control group, COPD patients had a significantly higher LLR level (p < 0.001). The disease was more serious in the high LLR group, which was reflected by Global Initiative for Chronic Obstructive Lung Disease (GOLD) and BMI, airway obstruction, dyspnoea, severe exacerbations (BODE) index and St. George’s Respiratory Questionnaire (SGRQ) index (p = 0.001, p = 0.013, p = 0.011, respectively). The forced expiration volume in 1 second (FEV₁) (p = 0.033) and forced expiratory volume in 1 second in percent of the predicted value (FEV₁%) (p = 0.009) in high LLR group were lower. Univariate and multivariate logistic regression analysis showed that LLR was an independent factor affecting the severity of COPD patients (odds ratio [OR] = 2.599, 95% CI: 1.266-5.337, p = 0.009). Conclusion We found that LLR is a novel biomarker in predicting the severity of patients with COPD. Further studies with larger database were recommended to verify our findings.

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.

Abstract
Abstract
Background
Many patients with chronic obstructive pulmonary disease (COPD) are treated in general practice only and have never received specialist care for COPD. They are seldom included in COPD cost studies but may account for a substantial proportion of the total costs.
Objective
To estimate and specify the total healthcare costs of patients who are treated for COPD in Denmark comparing those who have- and have not had specialist care for COPD.
Setting
Denmark, population 5.7 million citizens.
Methods
Via national registers, we specified the total healthcare costs of all + 30-years-old current users of respiratory pharmaceuticals. We identified the patients with COPD and compared those with at least one episode of pulmonary specialist care to those with GP care only.
Results
Among totally 329,428 users of respiratory drugs, we identified 46,084 with specialist-care- and 68,471 with GP-care-only COPD. GP-care-only accounted for 40% of the two populations’ total healthcare costs. The age- and gender-adjusted coefficient relating the individual total costs specialist-care versus GP-care-only was 2.19. The individual costs ranged widely and overlapped considerably (p25-75: specialist-care €2,175—€12,625, GP-care-only €1,110—€4,350). Hospital treatment accounted for most of the total cost (specialist-care 78%, GP-care-only 62%; coefficient 2.81), pharmaceuticals (specialist-care 16%, GP-care-only 27%; coefficient 1.28), and primary care costs (specialist-care 6%, GP-care-only 11%; coefficient 1.13). The total costs of primary care pulmonary specialists were negligible.
Conclusion
Healthcare policy makers should consider the substantial volume of patients who are treated for COPD in general practice only and do not appear in specialist statistics.

Int J Chron Obstruct Pulmon Dis 2021; 16:191-202.

Abstract
Background We explored the relationship between rural residency and in-hospital mortality in patients hospitalized with COPD exacerbations. Methods We retrospectively analyzed COPD hospitalizations from 2011 to 2017 at 124 acute care Veterans Health Administration (VHA) hospitals in the US. Patient residence was classified using Rural Urban Commuting Area codes as urban, rural, or isolated rural. We stratified patient hospitalizations into quartiles by travel time from patient residence to the nearest VHA primary care provider clinic and hospital. Multivariate analyses utilized generalized estimating equations with a logit link accounting for repeated hospitalizations among patients and adjusting for patient- and hospital-level characteristics. Results Of 64,914 COPD hospitalizations analyzed, 43,549 (67.1%) were for urban, 18,673 (28.8%) for rural, and 2,692 (4.1%) for isolated rural veterans. In-hospital mortality was 4.9% in urban, 5.5% in rural, and 5.2% in isolated rural veterans (P=0.008). Thirty-day mortality was 8.3% in urban, 9.9% in rural, and 9.2% in isolated rural veterans (P<0.001). Travel time to a primary care provider and VHA hospital was not associated with in-hospital mortality among isolated rural and rural veterans. In the multivariable analysis, compared to urban veterans, isolated rural patients did not have increased mortality. Rural residence was not associated with in-hospital (OR=0.87; 95% CI=0.67-1.12, P=0.28) but was associated with increased 30-day mortality (OR=1.13; 95% CI=1.04-1.22, P=0.002). Transfer from another acute care hospital (OR=14.97; 95% CI=9.80-17.16, P<0.001) or an unknown/other facility (OR=33.05; 95% CI=22.66-48.21, P<0.001) were the strongest predictors of increased in-hospital mortality compared to patients coming from the outpatient sector. Transfer from another acute care facility was also a risk factor for 30-day mortality. Conclusion Potential gaps in post-discharge care of rural veterans may be responsible for the rural-urban disparities. Further research should investigate the exact mechanism that inter-hospital transfers affect mortality.

Abstract
BACKGROUND Sepsis is more common in the elderly. TNF⍺ is recognized as an important mediator in sepsis and Toll-like receptors (TLRs) play an important role in initiating signaling cascades to produce TNF⍺. Little is known about how innate immunity is altered in healthy human aging that predisposes to sepsis. AIMS AND METHODS We tested the hypothesis that aging dysregulates the innate immune response to TLR 2 and 4 ligands. We performed whole blood assays on 554 healthy subjects aged 40-80 years. TNFα production was measured at baseline and after stimulation with the TLR2 agonists: peptidoglycan, lipoteichoic acid, Pam3CysK, Zymosan A and the TLR4 agonist lipopolysaccharide (LPS). In a subset of subjects (n = 250), we measured Toll-like receptor (TLR) 2, 4 and MyD88 expression using real-time PCR. RESULTS AND DISCUSSION We measured a 2.5% increase per year in basal secretion of TNFα with aging (n = 554 p = 0.02). Likewise, TNFα secretion was increased with aging after stimulation with peptidoglycan (1.3% increase/year; p = 0.0005) and zymosan A (1.1% increase/year p = 0.03). We also examined the difference between baseline and stimulated TNFα for each individual. We found that the increase was driven by the elevated baseline levels. In fact, there was a diminished stimulated response to LPS (1.9% decrease/year; p = 0.05), lipoteichoic acid (2.1% decrease/year p = 0.03), and Pam3CysK (2.6% decrease/year p = 0.0007). There were no differences in TLR or MyD88 mRNA expression with aging, however, there was an inverse relationship between TLR expression and stimulated TNFα production. CONCLUSIONS With aging, circulating leukocytes produce high levels of TNFα at baseline and have inadequate responses to TLR2 and TLR4 agonists. These defects likely contribute to the increased susceptibility to sepsis in older adults.

Abstract
Background We assessed direct and indirect costs associated with COPD in Sweden and examined how these costs vary across time, age, and disease stage in a cohort of patients with COPD and matched controls in a real-world, primary care (PC) setting. Patients and methods Data from electronic medical records linked to the mandatory national health registers were collected for COPD patients and a matched reference population in 52 PC centers from 2000 to 2014. Direct health care costs (drug, outpatient or inpatient, PC, both COPD related and not COPD related) and indirect health care costs (loss of income, absenteeism, loss of productivity) were assessed. Results A total of 17,479 patients with COPD and 84,514 reference controls were analyzed. During 2013, direct costs were considerably higher among the COPD patient population (€13,179) versus the reference population (€2,716), largely due to hospital nights unrelated to COPD. Direct costs increased with increasing disease severity and increasing age and were driven by higher respiratory drug costs and non-COPD-related hospital nights. Indirect costs (~€28,000 per patient) were the largest economic burden in COPD patients of working age during 2013. Conclusion As non-COPD-related hospital nights represent the largest direct cost, management of comorbidities in COPD would offer clinical benefits and relieve the financial burden of disease.

Abstract
PURPOSE We aimed to assess the effects of comorbidities on COPD costs and to investigate the relationship between comorbidities and clinical variables. PATIENTS AND METHODS All patients hospitalized with a diagnosis of COPD exacerbation between January 1, 2014, and December 31, 2014, at all state hospitals of Aydın province, a city located in the western part of Turkey, were included in this study. The costs examined in the study pertained to medications, laboratory tests, hospital stays, and other treatment-related factors, such as consumption of materials, doctor visits, and consultation fees. RESULTS A total of 3,095 patients with 5,237 exacerbations (mean age, 71.9±10.5 years; 2,434 males and 661 females) were evaluated. For 880 of the patients (28.9%), or 3,852 of the exacerbations (73.1%), at least one comorbid disease was recorded. The mean cost of each exacerbation was $808.5±1,586, including $325.1±879.9 (40.7%) for hospital stays, $223.1±1,300.9 (27.6%) for medications, $46.3±49.6 (0.9%) for laboratory expenditures, and $214±1,068 (26.5%) for other treatment-related factors, such as consumption of materials, doctor visits, and consultation fees. The cost of each exacerbation was $1,014.9 in patients with at least one comorbidity, whereas it was $233.6 in patients without comorbidity (P<0.001). Age >65 years, female gender, hospitalization in an intensive care unit, invasive or noninvasive mechanical ventilation, and a long duration of hospitalization were all found to be significant factors in increasing total costs during the exacerbations requiring hospitalization (P<0.05 for all). CONCLUSION Comorbidities have an important role in the total costs of acute exacerbations of COPD. Strategies for the prevention, diagnosis, and effective management of comorbidities would decrease the overall financial burden associated with acute exacerbations of COPD.

Abstract
COPD is the third-largest killer in the world, and certainly takes a toll on the health care system. Recurrent COPD exacerbations accelerate lung-function decline, worsen mortality, and consume over US$50 billion in health care spending annually. This has led to a tide of payment reforms eliciting interest in strategies reducing preventable COPD exacerbations. In this review, we analyze and discuss the evidence for COPD action plan-based self-management strategies. Although action plans may provide stabilization of acute symptomatology, there are several limitations. These include patient-centered attributes, such as comprehension and adherence, and nonadherence of health care providers to established guidelines. While no single intervention can be expected independently to translate into improved outcomes, structured together within a comprehensive integrated disease-management program, they may provide a robust paradigm.

Abstract
Background: Gastroesophageal reflux disease (GERD) is associated with frequent chronic obstructive pulmonary disease (COPD) exacerbations. Hiatal hernia (HH) contributes to GERD pathogenesis and is identifiable on chest high-resolution computed tomography (HRCT). We hypothesize that the presence of an HH on HRCT identifies those at increased risk for acute exacerbation of COPD. Methods: We retrospectively reviewed a prospectively enrolled cohort of smokers with and without airflow obstruction. HHs were identified visually on inspiratory HRCT. Individuals' demographic and clinical information was compared with secondary analysis performed using a propensity score generated matched cohort. Results: There were 523 COPD individuals and 607 unobstructed smokers. COPD individuals had more HHs than unobstructed smokers, (11.6% versus 6.1%, p < 0.001). COPD individuals with hernias were older, female, overweight and GERD positive as compared to those without hernia. There was no difference in self-reported exacerbation rates or hospitalizations per year, but similar severity of obstruction, smoking rates and long-term oxygen use. Analysis with the matched cohort revealed no significant difference in exacerbation rates. Conclusions: Presence of HHs on inspiratory HRCT scan did not predict worse symptoms or exacerbation rate in COPD individuals. Those with HHs were older, more obese, and predominantly female compared to those without HHs.

Abstract
Current guidelines limit regular use of inhaled corticosteroids (ICS) to a specific subgroup of patients with chronic obstructive pulmonary disease (COPD) in whom the forced expiratory volume in 1 s is <60% of predicted and who have frequent exacerbations. In these patients, there is evidence that ICS reduce the frequency of exacerbations and improve lung function and quality of life. However, a review of the literature suggests that the evidence available may be interpreted to favour or contradict these observations. It becomes apparent that COPD is a heterogeneous condition. Clinicians therefore need to be aware of the heterogeneity as well as having an understanding of how ICS may be used in the context of the specific subgroups of patients with COPD. This review argues for and against the use of ICS in COPD by providing an in-depth analysis of the currently available evidence.

Abstract
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Age and smoking are common risk factors for COPD and other illnesses, often leading COPD patients to demonstrate multiple coexisting comorbidities. COPD exacerbations and comorbidities contribute to the overall severity in individual patients. Clinical trials investigating the treatment of COPD routinely exclude patients with multiple comorbidities or advanced age. Clinical practice guidelines for a specific disease do not usually address comorbidities in their recommendations. However, the management and the medical intervention in COPD patients with comorbidities need a holistic approach that is not clearly established worldwide. This holistic approach should include the specific burden of each comorbidity in the COPD severity classification scale. Further, the pharmacological and nonpharmacological management should also include optimal interventions and risk factor modifications simultaneously for all diseases. All health care specialists in COPD management need to work together with professionals specialized in the management of the other major chronic diseases in order to provide a multidisciplinary approach to COPD patients with multiple diseases. In this review, we focus on the major comorbidities that affect COPD patients. We present an overview of the problems faced, the reasons and risk factors for the most commonly encountered comorbidities, and the burden on health care costs. We also provide a rationale for approaching the therapeutic options of the COPD patient afflicted by comorbidity.

Abstract
Background Low levels of physical activity are common in patients with chronic obstructive pulmonary disease (COPD), and a sedentary lifestyle is associated with poor outcomes including increased mortality, frequent hospitalizations, and poor health-related quality of life. Internet-mediated physical activity interventions may increase physical activity and improve health outcomes in persons with COPD. Methods/Design This manuscript describes the design and rationale of a randomized controlled trial that tests the effectiveness of Taking Healthy Steps, an Internet-mediated walking program for Veterans with COPD. Taking Healthy Steps includes an uploading pedometer, a website, and an online community. Eligible and consented patients wear a pedometer to obtain one week of baseline data and then are randomized on a 2:1 ratio to Taking Healthy Steps or to a wait list control. The intervention arm receives iterative step-count feedback; individualized step-count goals, motivational and informational messages, and access to an online community. Wait list controls are notified that they are enrolled, but that their intervention will start in one year; however, they keep the pedometer and have access to a static webpage. Discussion Participants include 239 Veterans (mean age 66.7 years, 93.7% male) with 155 randomized to Taking Healthy Steps and 84 to the wait list control arm; rural-living (45.2%); ever-smokers (93.3%); and current smokers (25.1%). Baseline mean St. George’s Respiratory Questionnaire Total Score was 46.0; 30.5% reported severe dyspnea; and the average number of comorbid conditions was 4.9. Mean baseline daily step counts was 3497 (+/- 2220). Veterans with COPD can be recruited to participate in an online walking program. We successfully recruited a cohort of older Veterans with a significant level of disability including Veterans who live in rural areas using a remote national recruitment strategy.

Abstract
Background COPD is a significant cause of morbidity and mortality in the Veterans Health Administration (VHA). To determine the clinical factors associated with the cost of COPD management, we analyzed the relationship between clinical characteristics and COPD healthcare costs at the Cincinnati VAMC. Methods We queried the VHA Decision Support System for patients diagnosed with COPD at the Cincinnati VAMC and calculated their VHA COPD-related encounters and costs in FY2008. Patients were ranked by COPD-related cost. We determined the detailed clinical characteristics of patients selected by modified systematic sampling and performed univariate and multivariable ordinary linear regression analysis to determine factors associated with cost. Results 3263 Veterans had 11,869 encounters with a primary or secondary diagnosis of COPD: 10,032 clinic visits, 505 emergency department (ED) visits, and 1,332 hospitalizations and incurred a total COPD-related healthcare cost of $21.4 M: $2.4 M clinic visits, $0.21 M ED visits, and $18.7 M hospitalizations and $0.89 M for COPD-related prescription costs. When the patients were ranked by VHA healthcare costs, the top 20% of patients accounted for 86% of the total costs and 57% of the total encounters with a primary or secondary diagnosis code of COPD and 90% of the total costs and 75% of the total encounters with a primary diagnosis code of COPD. The clinical characteristics and VHA healthcare costs of 840 of the 3263 unique individuals with COPD were analyzed to determine those characteristics associated with increased COPD-related costs. Univariate analysis showed significant associations with 24 clinical variables; the 4 most highly associated factors were nursing home residence, total hospital admissions, use of oral corticosteroids, and supplemental oxygen (p < 0.001 for all). In multivariate analysis, total number of admissions (p < 0.001), management by a pulmonologist (p < 0.001), number of clinic visits (p < 0.001), use of short acting anticholinergic (p = 0.001), forced expiratory volume in 1 second (FEV1) (p = 0.011), number of prescriptions (p = 0.011), body mass index (BMI) (p = 0.025), and use of inhaled corticosteroid (p = 0.043) were associated with COPD management cost. Conclusion The total number of admissions, clinic visits, physiologic impairment, BMI, number of medications, and type of provider are strongly associated with the total cost of COPD management. These factors may be used to focus COPD management toward patients with the potential for high utilization of healthcare resources.

Abstract
BACKGROUND There is paucity of data concerning the self-perceptions of health status and health-related quality of life (HRQoL) of veterans with multiple chronic medical conditions. MATERIAL AND METHODS Veterans who attended an out-patient power wheelchair clinic at a tertiary VA Medical Center were assessed. Health status and HRQoL were measured by using the EuroQol (EQ-5D) questionnaire. The EuroQol (ED-5D) visual analogue scale (EQ-5DVAS) measured their health state, and average values of the (EQ-5D) questionnaire for mobility, self-care, usual activities, pain or discomfort, and anxiety or depression (EQ-5Dprofile), and the EQ-5Dutility measured their HRQoL. RESULTS Of the 170 veterans who attended the out-patient clinic, the mean (±SD) age was 69.6±10.7 years, male/female ratio was 163/7, and 88% were non-Hispanic whites. Fifty-four percent were retired, 39% had a registered disabled, and only 3% were employed. Thirty-three percent were current smokers. More than 64% of the veterans had 4 or more co-morbid conditions for which they were receiving treatment. The mean (±SD) initial EQ-5Dprofile, EQ-5Dutility, and EQ-5DVAS scores were 10.3±1.5, 0.75±0.05 and 45.3±18.9, respectively. The social-demographic variables studied (age, gender, education, marital status, employment, co-morbid conditions, and current smoking history) were only able to predict the mobility and anxiety/depression domains of the EQ-5D. CONCLUSIONS Veterans who considered themselves disabled had multiple chronic medical conditions. Age, employment state, and number of chronic medical conditions were associated with poor health state and HRQoL. No relationship was found between health state and HRQoL in this sample of veterans.

Abstract
INTRODUCTION Long-acting beta-agonists (LABA) and/or inhaled corticosteroids (ICS) have been shown to reduce COPD exacerbation risk. Using data from a large integrated health-care system, we sought to examine whether these medication classes were initiated after an exacerbation of COPD. METHODS We identified patients who experienced an inpatient or outpatient COPD exacerbation within the Veterans Affairs Integrated Service Network (VISN)-20. We assessed the addition of a new inhaled therapy (an ICS, LABA or both) within 180 days after the exacerbation. We assessed independent predictors of adding treatment using logistic regression. RESULTS We identified 45,780 patients with COPD, of whom 2,760 patients experienced an exacerbation of COPD. Of these individuals, 2,570 (93.1 %) were on either none or only one long-acting medication studied (LABA or ICS). In the subsequent 180-day period after their exacerbation, only 875 (34.1 %) patients had at least one of these additional therapies dispensed from a VA pharmacy. Among patients who were treated in the outpatient setting, older age [OR 0.98/year, 95 % CI (0.97-0.99)], current tobacco use [OR 0.74, 95 % CI (0.60-0.90)], greater use of ipratropium bromide [OR 0.97/canister, 95 % CI (0.96-0.98)], prior COPD exacerbation [OR 0.55, 95 % CI (0.46-0.67)], depression [OR 0.77, 95 % CI (0.61-0.98)], CHF [OR 0.74, 95 % CI (0.57-0.97)], and diabetes (OR 0.77 (0.60-0.99)] were associated with lower odds of additional therapy. Patients who were treated in the hospital had similar associated predictors. CONCLUSION Among patients treated for an exacerbation of COPD, we found relatively few were subsequently prescribed inhaled therapies known to reduce exacerbations.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) patients present a high prevalence of cardiovascular disease. This excess of comorbidity could be related to a common pathogenic mechanism, but it could also be explained by the existence of common risk factors. The objective of this study was to determine whether COPD patients present greater cardiovascular comorbidity than control subjects and whether COPD can be considered a risk factor per se. Methods 1200 COPD patients and 300 control subjects were recruited for this multicenter, cross-sectional, case–control study. Results Compared with the control group, the COPD group showed a significantly higher prevalence of ischemic heart disease (12.5% versus 4.7%; P < 0.0001), cerebrovascular disease (10% versus 2%; P < 0.0001), and peripheral vascular disease (16.4% versus 4.1%; P < 0.001). In the univariate risk analysis, COPD, hypertension, diabetes, obesity, and dyslipidemia were risk factors for ischemic heart disease. In the multivariate analysis adjusted for the remaining factors, COPD was still an independent risk factor (odds ratio: 2.23; 95% confidence interval: 1.18–4.24; P = 0.014). Conclusion COPD patients show a high prevalence of cardiovascular disease, higher than expected given their age and the coexistence of classic cardiovascular risk factors.

Abstract
Purpose Pooled data were analyzed to evaluate the safety and tolerability of indacaterol, a once-daily inhaled long-acting β2-agonist for chronic obstructive pulmonary disease (COPD). Patients and methods Data were pooled from clinical studies of 3–12 months’ duration in patients with moderate-to-severe COPD receiving double-blind indacaterol 75 μg (n = 449), 150 μg (n = 2611), 300 μg (n = 1157), or 600 μg once daily (n = 547); formoterol 12 μg twice daily (n = 556); salmeterol 50 μg twice daily (n = 895); placebo (n = 2012); or tiotropium 18 μg once daily, given open label or blinded (n = 1214). Outcomes were adverse events, serious adverse events and deaths, plasma potassium, blood glucose, and QTc interval and vital signs. Results The commonest adverse events with indacaterol were COPD worsening, nasopharyngitis, and headache; most cases were mild or moderate and incidence was generally similar to placebo and other active treatments. The risk of acute respiratory serious adverse events (leading to hospitalization, intubation, or death) was not significantly increased with any of the active treatments compared with placebo. COPD exacerbation rates (analyzed in the intent-to-treat population) were significantly reduced with all active treatments versus placebo. Hazard ratios versus placebo for major cardiovascular adverse events were <1 for all indacaterol doses. Notable values for vital signs and measures of systemic β2-adrenoceptor activity were rare with indacaterol. The number of deaths adjusted per patient-year was lower with indacaterol (all doses combined) than with placebo (relative risk 0.21 [95% confidence interval 0.07–0.660], P = 0.008). Conclusion Indacaterol has a good profile of safety and tolerability that is appropriate for the maintenance treatment of patients with COPD.

Malnutrition is a serious condition in chronic obstructive pulmonary disease (COPD). Successful dietary intervention calls for calculations of resting metabolic rate (RMR). One disease-specific prediction equation for RMR exists based on mainly male patients. To construct a disease-specific equation for RMR based on measurements in underweight or weight-losing women and men with COPD, RMR was measured by indirect calorimetry in 30 women and 11 men with a diagnosis of COPD and body mass index <21 kg/m(2). The following variables, possibly influencing RMR were measured: length, weight, middle upper arm circumference, triceps skinfold, body composition by dual energy x-ray absorptiometry and bioelectrical impedance, lung function, and markers of inflammation. Relations between RMR and measured variables were studied using univariate analysis according to Pearson. Gender and variables that were associated with RMR with a P value <0.15 were included in a forward multiple regression analysis. The best-fit multiple regression equation included only fat-free mass (FFM): RMR (kJ/day) = 1856 + 76.0 FFM (kg). To conclude, FFM is the dominating factor influencing RMR. The developed equation can be used for prediction of RMR in underweight COPD patients.
