Cost-Effectiveness of Once-Daily Single-Inhaler COPD Triple Therapy in Spain: IMPACT Trial. Int J Chron Obstruct Pulmon Dis 2022; 17:3097-3109. [PMID: 36561129 PMCID: PMC9766529 DOI: 10.2147/copd.s366765] [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: 03/16/2022] [Accepted: 11/30/2022] [Indexed: 12/23/2022] Open
Abstract
Purpose Given between-country differences in healthcare systems, treatment costs, and disease management guidelines, country-specific cost-effectiveness analyses are important. This study evaluated the cost-effectiveness of once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI and UMEC/VI among patients with symptomatic chronic obstructive pulmonary disease (COPD) at risk of exacerbations from a Spanish healthcare system perspective. Patients and Methods Baseline data and treatment effects from the IMPACT trial were populated into the validated GALAXY COPD progression model. Utilities were estimated using Spanish observational data. Direct healthcare costs (2019 €) were informed by Spanish public sources. A 3% discount rate for costs and benefits was applied. The time horizon and treatment duration were 3 years (base case). One-way sensitivity, scenario, and probabilistic sensitivity analyses were performed. Results FF/UMEC/VI treatment resulted in fewer exacerbations over 3 years (4.130 vs 3.648) versus FF/VI, with a mean (95% confidence interval [CI]) incremental cost of €444 (€149, €713) per patient and benefit of 0.064 (0.053, 0.076) quality-adjusted life years (QALYs), resulting in an incremental cost-effectiveness ratio (ICER) of €6887 per QALY gained. FF/UMEC/VI was a dominant treatment strategy versus UMEC/VI, resulting in fewer exacerbations (4.130 vs 3.360), with a mean (95% CI) incremental cost of -€450 (-€844, -€149) and benefit of 0.054 (0.043, 0.064) QALYs. FF/UMEC/VI was cost-effective versus FF/VI and UMEC/VI across all analyses. Conclusion FF/UMEC/VI was predicted to be a cost-effective treatment option versus FF/VI or UMEC/VI in symptomatic COPD patients at risk of exacerbations in Spain, across all scenarios and sensitivity analyses.

Abstract
Purpose This study aims to identify the effects of patient and clinical therapy factors on the length of hospital stay (LOS) for admission due to chronic obstructive pulmonary disease (COPD) in Macao. Patients and Methods Health record of patients with COPD admitted to Kiang Wu Hospital from January 2017 to December 2019 was retrospectively analyzed. Demographic information, blood test results, clinical therapies, and LOS were described and analyzed by multivariable regression. Results A total of 1116 admissions were included with the average LOS being 12.28 (±9.23) days. Among them, 735 (66.6%) were male with mean age 79.42 (±10.35) years old, 697 were current or previous smokers (62.5%), and 360 (32.2%) had 3 or more comorbidities. During hospitalization, the most common treatments received were oxygen therapy (n=991,88.8%), antibiotics (n=828,74.2%), and systemic steroids (n=596,53.4%); only 120 (10.8%) had pulmonary rehabilitation (PR) and 128 (11.5%) received noninvasive ventilation (NIV). Inhaled medications were used during nearly 95% of hospitalization cases, while 2 and 3 types of inhaled medications were used during 230 (20.6%) and 582 (52.2%) hospitalization cases, respectively. Patient factors including age (B=0.178, 95% CI:0.535–1.072), being female (B=−1.147, 95% CI:-0.138–0.056), being current (B=−0.086, 95% CI:-0.124–0.018) or previous smoker (B=0.072, 95% CI:0.004–0.087), having 1, 2, 3 and over 3 comorbidities (B=0.126, 95% CI:0.034–0.147; B=0.125, 95% CI:0.031–0.144; B=0.116, 95% CI:0.028–0.146, B=0.090, 95% CI:0.021–0.166) and having low hemoglobin level (B=−0.118, 95% CI:-0.629- −0.214) exhibited significant associations with LOS. The use of NIV (B=0.080, 95% CI:0.022–0.138), pulmonary rehabilitation (B=0.269, 95% CI:0.212–0.327), two and three types of inhaled medications (B=0.109, 95% CI:0.003–0.166, B=0.255, 95% CI:0.083–0.237) were significantly associated with longer LOS (P<0.05). Conclusion NIV, PR and combined inhaled medications, which are often used for AECOPD, are the main clinical therapies associated with longer LOS in Macao. Smoking cessation, early treatments of comorbidities may be crucial to avoiding AECOPD and reducing LOS and disease burden.

Abstract
OBJECTIVE The aim of this study was to evaluate the quality of diagnosis and treatment of COPD using Big Data methodology on the Savana Manager 2.1 clinical platform. MATERIALS AND METHODS A total of 59,369 patients with a diagnosis of COPD were included from a population of 1,219,749 adults over 40 years of age. RESULTS In total, 78% were men. Spirometry data were available for only 26,453 (43.5%) subjects. Disease severity was classified in 18,172 patients: 4,396 mild, 7,100 moderate, and 6,676 severe, although only 27%, 34%, and 28%, respectively, presented obstructive spirometry. The clinical management of COPD is mainly the responsibility of the primary care and pulmonology departments, while internal medicine and, to a lesser extent, geriatrics also participate. Drug treatment was based on bronchodilators and inhaled corticosteroids (ICS). A marked decline in the use of long-acting beta-2 agonists (LABA) in monotherapy and a slight reduction in ICS/LABA combinations, associated with a LAMA in 74% of cases, was observed. All-cause in-hospital mortality among the overall population was 5.6% compared to 1% of the general population older than 40 years. In total, 35% were admitted to hospital, with an average stay of 6.6 days and a rate of hospital mortality in this group of 10.74%. DISCUSSION This study identifies the main features of an unselected COPD population and the major errors made in the management of the disease.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the most prevalent diseases in the World, and one of the most important causes of mortality and morbidity. In adults 40 years and older, it affects more than 10% of the population and has enormous personal, family and social burden. Tobacco smoking is its main cause, but not the only one, and there is probably a genetic predisposition that increases the risk in some patients. The paradigm of this disease is changing in Spain, with an increase of women that has occurred in recent years. Many of the physio pathological mechanisms of this condition are well known, but the psychological alterations to which it leads, the impact of COPD on relatives and caregivers, the limitation of daily life observed in these patients, and the economic and societal burden that they represent for the health system, are not so well-known. A major problem is the high under-diagnosis, mainly due to difficulties for obtaining, in a systematic way, spirometries in hospitals and health-care centers. For this reason, the Fundación de Ciencias de la Salud and the Spanish National Network Center for Research in Respiratory Diseases (CIBERES) have brought together experts in COPD, patients and their organizations, clinical psychologists, experts in health economics, nurses and journalists to obtain their opinion about COPD in Spain. They also discussed the scientific bibliometrics on COPD that is being carried out from the CIBERES and speculated on the future of this condition. The format of the meeting consisted in the discussion of a series of questions that were addressed by different speakers and discussed until a consensus conclusion was reached.

Abstract
Purpose COPD has been associated with a high number of comorbidities and a relatively high level of health care resource utilization. This study aimed to estimate the social economic impact of COPD in the autonomous community of Extremadura (Spain) in 2015. Patients and methods This is a retrospective observational study carried out using a representative sample of patients diagnosed with COPD in Extremadura. Sociodemographic data, data on health care resource utilization, formal and informal care received by the patients, and loss of labor productivity in the last 12 months were collected through an electronic data collection platform. Direct health care costs were estimated using the bottom-up approach, costs of informal care were assessed using the substitution method, and labor productivity losses were calculated using the human capital method. Results A sample of 386 patients was obtained (mean age: 71.8±10.3 years, males: 76.2%). The results show an average annual cost per patient of 3,077 euros. Direct health care costs represented 43.8% (1,645 euros), direct non-health care costs amounted to 38.3% (1,440 euros), and labor productivity losses represented 17.9% (672 euros) of the average annual cost. The total annual cost of patients with COPD in Extremadura reached 36.2 million euros in 2015. Conclusion COPD poses a significant burden for the health care system and the society of Extremadura. The implementation of preventive and control measures could result in a substantial reduction in the economic impact.

Abstract
BACKGROUND AND AIMS Modelling return on investment (ROI) from smoking cessation interventions requires estimates of their costs and benefits. This paper describes a standardized method developed to source both economic costs of tobacco smoking and costs of implementing cessation interventions for a Europe-wide ROI model [European study on Quantifying Utility of Investment in Protection from Tobacco model (EQUIPTMOD)]. DESIGN Focused search of administrative and published data. A standardized checklist was developed in order to ensure consistency in methods of data collection. SETTING AND PARTICIPANTS Adult population (15+ years) in Hungary, Netherlands, Germany, Spain and England. For passive smoking-related costs, child population (0-15 years) was also included. MEASUREMENTS Costs of treating smoking-attributable diseases; productivity losses due to smoking-attributable absenteeism; and costs of implementing smoking cessation interventions. FINDINGS Annual costs (per case) of treating smoking attributable lung cancer were between €5074 (Hungary) and €52 106 (Germany); coronary heart disease between €1521 (Spain) and €3955 (Netherlands); chronic obstructive pulmonary disease between €1280 (England) and €4199 (Spain); stroke between €1829 (Hungary) and €14 880 (Netherlands). Costs (per recipient) of smoking cessation medications were estimated to be: for standard duration of varenicline between €225 (England) and €465 (Hungary); for bupropion between €25 (Hungary) and €220 (Germany). Costs (per recipient) of providing behavioural support were also wide-ranging: one-to-one behavioural support between €34 (Hungary) and €474 (Netherlands); and group-based behavioural support between €12 (Hungary) and €257 (Germany). The costs (per recipient) of delivering brief physician advice were: €24 (England); €9 (Germany); €4 (Hungary); €33 (Netherlands); and €27 (Spain). CONCLUSIONS Costs of treating smoking-attributable diseases as well as the costs of implementing smoking cessation interventions vary substantially across Hungary, Netherlands, Germany, Spain and England. Estimates for the costs of these diseases and interventions can contribute to return on investment estimates in support of national or regional policy decisions.

Abstract
BACKGROUND AND AIMS Although clear benefits are associated with reducing smoking, there is increasing pressure on public health providers to justify investment in tobacco control measures. Decision-makers need tools to assess the Return on Investment (ROI)/cost-effectiveness of programmes. The EQUIPT project adapted an ROI tool for England to four European countries (Germany, the Netherlands, Spain and Hungary). EQUIPTMOD, the economic model at the core of the ROI tool, is designed to assess the efficiency of packages of smoking cessation interventions. The objective of this paper is to describe the methods for EQUIPTMOD and identify key outcomes associated with continued and cessation of smoking. METHODS EQUIPTMOD uses a Markov model to estimate life-time costs, quality-adjusted life years (QALYs) and life years associated with a current and former smoker. It uses population data on smoking prevalence, disease prevalence, mortality and the impact of smoking combined with associated costs and utility effects of disease. To illustrate the tool's potential, costs, QALYs and life expectancy were estimated for the average current smoker for five countries based on the assumptions that they continue and that they cease smoking over the next 12 months. Costs and effects were discounted at country-specific rates. RESULTS For illustration, over a life-time horizon, not quitting smoking within the next 12 months in England will reduce life expectancy by 0.66, reduce QALYs by 1.09 and result in £4961 higher disease-related health care costs than if the smoker ceased smoking in the next 12 months. For all age-sex categories, costs were lower and QALYs higher for those who quit smoking in the 12 months than those who continued. CONCLUSIONS EQUIPTMOD facilitates assessment of the cost effectiveness of smoking cessation strategies. The demonstrated results indicate large potential benefits from smoking cessation at both an individual and population level.

Cost-effectiveness of alternative smoking cessation scenarios in Spain: results from the EQUIPTMOD. Addiction 2018; 113 Suppl 1:65-75. [PMID: 29532966 PMCID: PMC6032934 DOI: 10.1111/add.14090] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Revised: 08/07/2017] [Accepted: 11/02/2017] [Indexed: 12/02/2022]
Abstract
AIMS To assess the cost-effectiveness of alternative smoking cessation scenarios from the perspective of the Spanish National Health Service (NHS). DESIGN We used the European study on Quantifying Utility of Investment in Protection from Tobacco model (EQUIPTMOD), a Markov-based state transition economic model, to estimate the return on investment (ROI) of: (a) the current provision of smoking cessation services (brief physician advice and printed self-helped material + smoking ban and tobacco duty at current levels); and (b) four alternative scenarios to complement the current provision: coverage of proactive telephone calls; nicotine replacement therapy (mono and combo) [prescription nicotine replacement therapy (Rx NRT)]; varenicline (standard duration); or bupropion. A rate of 3% was used to discount life-time costs and benefits. SETTING Spain. PARTICIPANTS Adult smoking population (16+ years). MEASUREMENTS Health-care costs associated with treatment of smoking attributable diseases (lung cancer, coronary heart disease, chronic obstructive pulmonary infection and stroke); intervention costs; quality-adjusted life years (QALYs). Costs and outcomes were summarized using various ROI estimates. FINDINGS The cost of implementing the current provision of smoking cessation services is approximately €61 million in the current year. This translates to 18 quitters per 1000 smokers and a life-time benefit-cost ratio of 5, compared with no such provision. All alternative scenarios were dominant (cost-saving: less expensive to run and generated more QALYs) from the life-time perspective, compared with the current provision. The life-time benefit-cost ratios were: 1.87 (proactive telephone calls); 1.17 (Rx NRT); 2.40 (varenicline-standard duration); and bupropion (2.18). The results remained robust in the sensitivity analysis. CONCLUSIONS According to the EQUIPTMOD modelling tool it would be cost-effective for the Spanish authorities to expand the reach of existing GP brief interventions for smoking cessation, provide pro-active telephone support, and reimburse smoking cessation medication to smokers trying to stop. Such policies would more than pay for themselves in the long run.

Abstract
COPD is a common, preventable, and treatable disease characterized by persistent airflow obstruction associated with enhanced inflammation in the airways and the lung in response to noxious particles or gases. Clinical history and pulmonary function testing are necessary for accurate diagnosis. While exposure to tobacco smoke remains a common cause, other etiologies and underlying genetic predisposition play significant roles. Treatment options are numerous and should be individualized based on symptoms and exacerbation frequency.

Abstract
BACKGROUND An understanding of the humanistic and economic burden of individuals with symptomatic chronic obstructive pulmonary disease (COPD) is required to inform payers and healthcare professionals about the disease burden. OBJECTIVES The aim of this systematic review was to identify and present humanistic [health-related quality of life (HRQoL)] and economic burdens of symptomatic COPD. METHODS A comprehensive search of online databases (reimbursement or claims databases/other databases), abstracts from conference proceedings, published literature, clinical trials, medical records, health ministries, financial reports, registries, and other sources was conducted. Adult patients of any race or gender with symptomatic COPD were included. Humanistic and economic burdens included studies evaluating HRQoL and cost and resource use, respectively, associated with symptomatic COPD. RESULTS Thirty-two studies reporting humanistic burden and 74 economic studies were identified. Symptomatic COPD led to impairment in the health state of patients, as assessed by HRQoL instruments. It was also associated with high economic burden across all countries. The overall, direct, and indirect costs per patient increased with an increase in symptoms, dyspnoea severity, and duration of disease. Across countries, the annual societal costs associated with symptomatic COPD were higher among patients with comorbidities. CONCLUSIONS Symptomatic COPD is associated with a substantial economic burden. The HRQoL of patients with symptomatic COPD is, in general, low and influenced by dyspnoea.

Abstract
Chronic obstructive pulmonary disease (COPD) is an enormous public health problem and of growing importance due to its high prevalence, elevated morbimortality, and socioeconomic costs. Many Spanish epidemiological studies report a prevalence of 10% of the adult population, with its growth appearing to have stabilised. Nevertheless, over 75% of cases are still underdiagnosed. The diagnosis of mild and moderate obstruction is associated with a higher survival and lower costs (14 years and €9,730) compared to 10 years survival and €43,785 of patients diagnosed in the severe obstruction phase. COPD was the fourth cause of death in Spain in 2011, although the adjusted mortality rates have decreased more than 20% in the last decade, particularly in males. Patients with advanced COPD die from it, but patients with mild or moderate COPD die due to cardiovascular diseases or cancer (mainly of the lung). It is estimated that the annual cost of the disease is around 3,000 million Euros. These increase with the spirometric severity, and is mainly associated with exacerbations (almost 60% of the direct costs). Comorbidity, that is the presence of diseases that coexist with the studied disease, is higher in patients with COPD than in the general population and affects health results.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death and disability worldwide, but before the development of several new pharmacological treatments little could be done for COPD patients. Recognition that these new treatments could significantly improve the prognosis for COPD patients has radically changed clinical management guidelines from a palliative philosophy to an aggressive approach intended to reduce chronic symptoms, improve quality of life and prolong survival. These new treatments have also sparked interest in COPD cost-effectiveness research. Most COPD cost-effectiveness studies have been based on clinical trial populations, limited to direct medical costs, and used standard analysis methods such as Markov modelling, and they have usually found that newer therapies have favourable cost effectiveness. However, new insights into the clinical progression of COPD bring into question some of the assumptions underlying older analyses. In this review, we examine clinical factors unique to COPD and recent changes in clinical perspectives that have important implications for pharmacoeconomic analyses. The main parameters explored include (i) the high indirect medical costs for COPD and their relevance in assessing the societal benefits of new therapy; (ii) the importance of acute deteriorations in COPD, known as exacerbations, and approaches to modelling the cost benefit of exacerbation reduction; (iii) quality/utility instruments for COPD; (iv) the prevalence of co-morbid conditions and confounding between COPD and co-morbid disease utilization; (v) the limitations of Markov modelling; and (vi) the problem of outliers.

Abstract
BACKGROUND The objective of this study was to determine the level of knowledge about chronic obstructive pulmonary disease (COPD) and its determinants in the general population of Spain, and to compare it with a similar survey conducted in 2002. METHODS We conducted a cross-sectional, observational, epidemiological study in September 2011 by means of a telephone interview with a representative sample of individuals aged 40-80 years living in all 17 regions of Spain. RESULTS A total of 6,528 responses were obtained (response rate of 13.1%), 53% of respondents were females with a mean age of 59.8 years. Regarding tobacco use, 19.4% were current smokers while 27.9% reported being former smokers. Only 17.0% spontaneously recognized the term «COPD». Valencia was the region with the highest degree of ignorance regarding COPD (91%), while Aragon had the lowest (73.7%). Nevertheless, COPD is considered a severe disease, following angina pectoris in severity. Upon comparing these results with the previous survey from 2002, we observed significant improvements in the knowledge and understanding of COPD (8.6% vs. 17.0%), with a marked variability between the regions (P<.05). Currently, only 4.7% of the Spanish population knows that there is a National Strategy for COPD, although 86.0% have a favorable or very favorable opinion about the new Anti-tobacco Law. CONCLUSION The lack of knowledge about COPD and its determinants in the general population remains high compared to 2002; thus, more and better educational and awareness programs are necessary.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the main causes of death in Spain and elsewhere in the world, with an estimated 18,000 and 2.75 million deaths annually. Mortality is predicted to increase in the next few years due to smoking and the aging population. Multiple studies confirm that COPD is underreported as a cause of death on death certificates, due to the difficulty of determining the final cause of death in these patients. The main causes of mortality in COPD range from lung cancer and cardiovascular disease in patients with mild COPD to respiratory failure in the most advanced stages. Fortunately, in the latest updates, guidelines for the management and treatment of the disease identify reduction of mortality as one of the main clinical objectives to be achieved in these patients.

Abstract
Chronic obstructive pulmonary disease (COPD) poses a significant economic burden on society, and a substantial portion is related to exacerbations of COPD. A literature review of the direct and indirect costs of COPD exacerbations was performed. A systematic search of the MEDLINE database from 1998-2008 was conducted and supplemented with searches of conference abstracts and article bibliographies. Articles that contained cost data related to COPD exacerbations were selected for in-depth review. Eleven studies examining healthcare costs associated with COPD exacerbations were identified. The estimated costs of exacerbations vary widely across studies: $88 to $7,757 per exacerbation (2007 US dollars). The largest component of the total costs of COPD exacerbations was typically hospitalization. Costs were highly correlated with exacerbation severity. Indirect costs have rarely been measured. The wide variability in the cost estimates reflected cross-study differences in geographic locations, treatment patterns, and patient populations. Important methodological differences also existed across studies. Researchers have used different definitions of exacerbation (e.g., symptom- versus event-based definitions), different tools to identify and measure exacerbations, and different classification systems to define exacerbation severity. Unreported exacerbations are common and may influence the long-term costs of exacerbations. Measurement of indirect costs will provide a more comprehensive picture of the burden of exacerbations. Evaluation of pharmacoeconomic analyses would be aided by the use of more consistent and comprehensive approaches to defining and measuring COPD exacerbations.

Abstract
Aim: To analyze the accuracy of diagnosis in a population receiving inhaled therapies due to respiratory diseases in a primary care setting. Method: Noninterventional, multicenter, cross-sectional, observational epidemiologic study methodology. Results: A total of 9752 subjects were evaluated. Of these, 4188 (42.9%) patients were diagnosed with asthma, 4175 (42.8%) with chronic obstructive pulmonary disease (COPD), and 1389 had a diagnosis of disease of unknown origin. Of those over the age of 40 years, 4079 (50.9%) had COPD and 2877 (35.9%) had asthma. Sixty percent of the subjects were men, and the proportion of men was higher in patients with COPD (83.2%) than in the group with asthma (39.8%, P < 0.0001). Of subjects with COPD, 17.3% had mild, 55.3% had moderate, 24.1% had severe, and 3.2% had very severe disease. With regard to the level of severity of asthma, 34.9% of subjects had intermittent, 34.6% had mild persistent, 27.1% had moderate persistent, and 3.5% had severe persistent disease. Only 13.9% of patients in the COPD group had all the characteristics of COPD based on the Global Initiative for Chronic Obstructive Lung Disease criteria and an absence of the characteristics of asthma. Conclusions: The majority of patients receiving inhaled therapy in primary care did not have an accurate diagnosis according to current international guidelines for COPD and asthma. More initiatives for improving diagnostic accuracy in respiratory diseases must be implemented in primary care.

Abstract
Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States. Acute exacerbations of COPD account for up to 84% of the total economic cost of this disease. The altered mechanics of the COPD patient represent a unique challenge to the clinician instituting assisted ventilation in this population. We developed an alternative mode of limited extracorporeal support termed Venovenous carbon dioxide removal (VVCO2R). We report our first case using VVCO2R, a 42-year-old white woman with a history of COPD and asthma, who was a heavy smoker at the time of admission. We utilized a compact, low flow pediatric extracorporeal circuit interposed with a low resistance gas exchange device. Venovenous carbon dioxide removal allowed for a reduction in the patient's minute ventilation to 30% of baseline with improved arterial blood gases (ABGs), a reduction in peak airway pressures and improvement in her hyperinflation. Our experience demonstrates that this system can effectively remove CO2 safely in a single cannula venous configuration while maintaining minimal anticoagulation. We believe this system could potentially be utilized in any medical or surgical intensive care unit.

Abstract
Objectives 1) To estimate the annual cost of patients with stable chronic obstructive pulmonary disease (COPD) followed in primary care in Spain; 2) To analyze the possible cost predictor variables. Patients and methods A multicenter, epidemiological, observational, descriptive study. Sociodemographic data, severity of disease, associated comorbidity, treatment followed by patients, quality of life (SF-12 questionnaire), health care resource utilization in the previous 12 months and duration of working disability due to COPD were collected. Results A total of 10,711 patients (75.6% men; 24.4% women) with a mean age of 67.1 ± 9.66 years were evaluated. The mean forced expiratory volume in one second (FEV1) value was 57.4 ± 13.4%. The total cost per patient per year was €1,922.60 ± 2,306.44. The largest component of this cost was hospitalization (€788.72 ± 1,766.65), followed by cost of drugs (€492.87 ± 412.15) and visits to emergency rooms (€134.32 ± 195.44). Linear regression analysis found associated heart disease, FEV1, physical component of quality of life, number of medical visits (primary care physician, pneumologist and emergency room), hospital admissions (frequency and duration of stay) and duration of working disability to be significant predictors of the total annual cost. Conclusions The total annual cost of a COPD patient followed in primary care in Spain was considered high in this study. The presence of associated heart disease, severity of airflow obstruction, physical component of quality of life, health care resource utilization and duration of work disability were found to be predictor of cost.

Abstract
BACKGROUND Health-related quality of life measures are widely used in patients with chronic obstructive pulmonary disease (COPD). However, they are extremely limited when used to evaluate patients outside the clinical trials. The aim of this study was to analyse the burden of the disease using a simple, validated, self-administered questionnaire specifically developed for patients in daily clinical practice. METHODS A total of 3935 patients (74.5% men; mean age, 67 years) participated in a cross-sectional study. The burden of COPD on patients was measured using the Clinical COPD Questionnaire (CCQ). COPD was rated at four levels by the forced expiratory volume in one second (FEV(1)) according to The Global Initiative for Chronic Obstructive Lung Disease (GOLD) scale. RESULTS The disease mainly affects old men (more than 50% were over 65 years of age) and non-employed men (23% were employed). Of the patients studied, 22.7% continued smoking, especially men (24.4% of men vs. 18.1% of women). Most patients (54%) were diagnosed with moderate stage II COPD. Severity of COPD was lower in women: 29.6% of men had severe COPD compared with 13.7% of women. During the last year, 65.1% had at least one acute exacerbation and 36.6% were admitted to hospital because of COPD exacerbation. No association was found between the body mass index and COPD stage. The variable that most influenced the disease burden was dyspnoea, as progression from grade 0 to grade 4 increased the disease burden by 1.78 points for symptoms, 2.43 for functional state and 1.53 for mental state. The functional classification of COPD also had a significant influence on the disease burden. CONCLUSIONS The present findings show that dyspnoea and the degree of airflow limitation are the clinical variables that most affect the burden of COPD from the patient's point of view.

Abstract
Exacerbations of chronic obstructive pulmonary disease (COPD) have serious health consequences for patients and are strongly associated with unscheduled healthcare resource use. This study used a preference-based quality of life measure questionnaire (EQ-5D) to evaluate the impact of exacerbation on health status and utility during a patient's admission to hospital and short-term follow-up. Costs of admission were calculated. In total, 149 patients consented to take part in the study representing 222 admissions to hospital. At admission patients reported high levels of problems for all dimensions of the EQ-5D. Mean utility (-0.077) and Visual Analogue Scale (25.9) values indicated great impairment, with 61% of patients having a negative utility value representing a health state equivalent to 'worse than death' at admission. Many problems were still reported at discharge. By 3 months follow-up patients had deteriorated, with percentages of patients reporting problems in mobility (98%) and usual activity (88%) almost back up to admission levels. Health status and utility values were similar regardless of lung function at admission and at discharge. Approximately half of the patients in each category had a negative utility value at admission representing a health state 'worse than death', with similar levels of improvement by discharge. The mean cost of an admission was 2130.34 pounds (SD 1326.09) with only a mean of 110.37 pounds(5%) because of medication. No differences were noted by lung function category. In conclusion, all COPD patients requiring admission for an exacerbation suffer a serious deterioration in health status which, although improves during admission, notably deteriorates by 3 months postdischarge.

Abstract
We investigated changes in the geography of Chronic Obstructuve Pulmonary Disease (COPD) hospitalization charges in California over the period of 1993 and 1999. There is little information available at less than the county level for this increasingly costly disease in California. We found, using a uniform grid unit method, (4X4 and 16X16 mile urban and rural grids respectively, using zip codes as the base source for information) positive relationships between COPD charges and age, percentage Hispanics, and number of tobacco outlets. Further, inverse relationships were found between the incidence of COPD charges and income level and the percentage of the population with undergraduate degrees. When examining "hotspot" grid units, we found that COPD was clearly associated with minority/immigrant status and depressed socio-economic measures, suggesting the need for better smoking interventions among persons of color and the poor. In summary, the Los Angeles area had a marked increase in hotspots both in 1993 and 1999, and also experienced a significant increase in COPD hospitalization charges between 1993 and 1999. Transforming zip code level data into a uniform grid allows for relatively simple comparisons across time, without such a transformation, such temporal comparisons are extremely difficult to implement. This more, "fine grained" geographical analysis allows public health planners a better platform than is typically available to assess changes in COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality in the United States. In 2000, an estimated 10.5 million people had COPD, of which more than 7.2 million were from the under-age 65 employed population. The prevalence of COPD in the workforce population was substantial with 46.5% of current employment among adults having the disease. However, the cost burden in the employed population is unknown. We examined COPD prevalence and costs in a large employment-based population. Using claims data from 1999 to 2003, we estimated the cost associated with COPD-related hospitalizations, emergency department visits, outpatient services, and prescription drug use. Per patient use of hospital care for COPD decreased during 1999 through 2003, including a decrease in the number of hospital admissions (from 0.10 in 1999 to 0.04 in 2003) and in the length of stay in hospitals (from 0.53 in 1999 to 0.17 in 2003). The number of outpatient visits, however, increased from 3.45 in 1999 to 3.80 in 2003. COPD-related per patient total medical costs decreased from $1460 in 1999 to $1138 in 2003 largely because of a decrease in the cost of hospitalizations for COPD. In contrast, mean per patient expenditures for outpatient services increased over the same period from $243 in 1999 to $295 in 2003. The cost of COPD to employers is high, but the cost could be reduced by programs aimed at preventing new cases of COPD, reducing hospitalizations, and providing more outpatient services to COPD patients.

Abstract
QUESTION OF THE STUDY To assess the impact of prescribing pulmonary drugs according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines on direct costs in stable chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS A total of 560 ambulatory COPD patients completed a specific questionnaire that included data regarding drug therapy. Severity was graded according to the British Thoracic Society (BTS) criteria and appropriateness of pharmacological treatment according to GOLD guidelines. RESULTS Annual direct costs were 1,657 EUR in stage I, 2,425 EUR in stage II, and 3,303 EUR in stage III. The mean direct costs was 2,061 EUR (38% corresponded to drug therapy). Medication accounted for 43%, 37.6%, and 28.4% of total direct costs for stage I, II, and III, respectively. Inhaled steroids and long-acting beta2-agonists accounted for 78%, 76%, and 75% of total drugs costs in stages I, II, and III, respectively. Drug therapy which was not in accordance with guidelines accounted for 78.7% and 54% of total drug costs in stages I and II, respectively. Most patients with severe disease were treated adequately. ANSWER TO THE QUESTION: Pharmacologic treatment has a great impact on direct medical costs in stable COPD. According to GOLD guidelines, patients with mild or moderate COPD are frequently treated with nonrecommended drugs.

Abstract
The objective of this 1-week cross-sectional survey was to assess the clinical features of outpatients with chronic obstructive pulmonary disease (COPD). A one-page questionnaire was used to collect demographic data, smoking status, and COPD-related variables. Ten or 20 consecutive patients were selected from Primary care or specialised setting during a week. Pulmonary function (FEV1) was measured using an electronic device (Piko-1). The study sample comprised 11,973 COPD patients (83% men) with a mean (sd) age of 67 (10.7) years. Thirty-five percent of patients were current smokers and smoked a mean of 17.4 (9.9) cigarettes daily. COPD severity according to GOLD stages was mild in 20% of patients, moderate in 38%, severe in 30%, and very severe in 12%. A higher percentage of men showed severe (33%) or very severe (14%) disease compared to women (16% and 6%, respectively) (P<0.005). Forty-two percent of patients had severe functional impairment and 35% continued smoking. Moreover, 11% of patients with very severe COPD smoked more than 20 cigarettes a day. The mean frequency of visits in the previous year was every 4.6 (4.1) months, with cough as the main reason for consultation. The most commonly used drugs were long-acting beta2-agonists (78%) and inhaled steroids (77%). Inhaled steroids were used by 84% of patients with very severe, 82% with severe disease, 73% with moderate disease, and 69% with mild disease (chi2 for trend, P<0.0001). This survey carried out in a real life setting shows that 42% of the patients who completed the questionnaire had severe COPD, 35% of them continued smoking, and 69% of patients with mild COPD used inhaled steroids.

Abstract
COPD is a major cause of morbidity and mortality in Europe. The purpose of this literature review was to critically evaluate published data on COPD prevalence and the cost of COPD interventions in European countries. Selection of literature was based on article retrieval from a systematic literature search using PubMed and EMBASE. Only articles providing data in European countries published between January 1990 and March 2003 were included. European epidemiological (cross-sectional, cohort, case-control) and economic (cost-of-illness-, cost-minimization-, cost-effectiveness-, cost-benefit-, cost-utility-analysis) studies were included. Of 74 retrieved epidemiologic studies, only seven (9%) fulfilled the inclusion criteria. In the selected literature, COPD prevalence ranged from 3% among Finnish women to 57% among Italian men and women, 45 years and older. Of 56 economic studies, 24 satisfied entry criteria. Results from the final cost-of-illness studies indicated that hospital care and medication represented the major portion of costs associated with COPD. In a survey conducted in 1998/99, annual direct expenditures for COPD treatment per patient in Europe ranged from Euro 530 in France to Euro 3238 in Spain. There was a differential increase in COPD prevalence predominantly related to an aging patient population, with a high incidence of exposure to cigarette smoke. Data also showed differences in the economic impact of COPD in Europe based on the proportion of patients with severe COPD, frequency of exacerbations, and number of hospitalizations. Overall, results of this review demonstrated the need for global epidemiologic and economic studies to allow for more uniform guidelines for the prevention and cost-effective treatment of patients with COPD.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a major health problem. Few data about COPD economic burden are available. METHODS SCOPE was an observational economical retrospective and prospective study conducted in France in 2001, by 114 general practitioners (GPs) and 57 lung specialists. The aim was to describe the burden of COPD patients and to estimate the annual cost according to severity stages. Health resource utilization was collected by questionnaires over a 12-month period for 285 patients. RESULTS It was a cost-of-illness analysis. COPD patients followed by a lung specialist were more severe than patients followed by a GP and had a higher level of medical resource consumption. The COPD disease and its complications explained 66% of the total cost. The main cost drivers were inpatient care (35%, or 1509,9 euros/year/patient) and prescription medications (31%, or 1340,6 euros/year/patient). The direct total cost varied according to COPD severity on account of inpatient care and respiratory assistance. DISCUSSION This study confirmed the economic burden of COPD in France. Actions allowed to slow down the disease's evolution and to anticipate the exacerbation could reduce the cost.

Abstract
Chronic obstructive pulmonary disease (COPD) is an obstructive lung disorder characterized by progressive airflow limitation that is not reversible or only partially reversible, including chronic bronchitis and emphysema. Confronting COPD in North America and Europe was the first large-scale international survey to attempt to quantify the country-specific burden of the disease, collecting data on clinical outcomes, healthcare resource utilization, and lost productivity, from patients and physicians in France and seven other countries. The economic analysis of the French survey results showed that patients with COPD required considerable utilization of healthcare resources, with annual direct costs estimated at Euro 530 per patient In addition, COPD-related illness or disability prevented many patients from working, with an estimated annual indirect cost of Euro 1078 per patient The survey suggested underdiagnosis and undertreatment of COPD by healthcare professionals, and patients reported poor symptom control. The cost of unscheduled care (Euro 151) was almost double the cost of scheduled visits to healthcare professionals (Euro 82). This suggests that improving the long-term management of chronic symptoms by healthcare professionals could reduce the burden of disease. As in other countries, the clinical management of COPD in France may be improved by following guideline recommendations for COPD treatment. These include smoking cessation at all stages of the disease, regular treatment of chronic symptoms with bronchodilators in dyspnoeic patients, and pulmonary rehabilitation. The results of the survey also showed that the societal cost of COPD was considerably greater in patients with severe disease (Euro 2882) compared with mild COPD (Euro 289). This suggests that interventions that could help delay the progression of COPD to the advanced stages of the disease (such as smoking cessation) could be of economic benefit.

Abstract
Chronic obstructive pulmonary disease (COPD) is a condition characterized by progressive airflow limitation, which causes considerable morbidity and mortality worldwide. Yet the burden of COPD is poorly recognized, and the disease remains an inadequately managed health problem. Few studies have attempted to quantify the impact of the disease on patient health, the healthcare system and society as a whole. This provided the rationale for Confronting COPD in North America and Europe, the first large-scale international survey of the burden of COPD. This paper describes how quantitative measures of healthcare resource utilization and workplace productivity loss were derived from patient responses to the Confronting COPD survey, to investigate the country-specific impact of COPD on the healthcare system and society. The aim of this analysis is to inform countries of the economic impact of the condition, and demonstrate the need for better COPD treatment to improve health and reduce the sizeable burden of this disease.

Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive disorder of airflow limitation that is not fully reversible, with disabling symptoms including chronic cough and dyspnoea. Although a number of studies in the U.S.A. have assessed the impact of COPD on the healthcare system and society, data on healthcare resource utilization (particularly outpatient services and medication use) in patients with mild to moderate COPD, or patients who meet symptom criteria for COPD but have not received this diagnosis, are limited or unavailable. To fill gaps in current knowledge about the impact of this disease, an economic analysis was conducted on the data collected from patients enrolled in the U.S.A. sample of Confronting COPD in North America and Europe, the first large-scale international survey of the burden of the disease. The annual cost of healthcare resource utilization was estimated at US dollar 4119 per patient with COPD, with indirect (non-medical care) costs amounting to US dollar 1527 per patient. The annual estimated societal cost was therefore US dollar 5646 per patient. The majority of disease costs in the survey were associated with inpatient hospitalizations (US dollar 2891). The results of the survey suggest that interventions that improve COPD outcomes by decreasing symptoms and preventing acute exacerbations could substantially decrease the costs associated with this disease.

Abstract
An economic analysis of data from a large-scale international survey, Confronting COPD in North America and Europe, was conducted in seven countries (Canada, France, Italy, The Netherlands, Spain, the U.K and the U.SA.), to investigate the burden of chronic obstructive pulmonary disease (COPD). The results demonstrated the high economic impact of COPD on the healthcare system and society in each country. The mean annual direct costs of the disease were particularly high in the U.S.A. (US dollar 4119 per patient) and Spain (US dollar 3196 per patient) but relatively low in The Netherlands (US dollar 606) and France (US dollar 522). Lost productivity due to COPD had a particularly high impact on the economy in France, The Netherlands and the U.K, accounting for 67%, 50% and 41% of overall costs, respectively. The total societal cost of COPD per patient ranged from over US dollar 5646 in the U.S.A. to US dollar 1023 in The Netherlands. In five out of seven countries, the majority (52-84%) of direct costs associated with COPD were due to inpatient hospitalizations. As acute exacerbations of COPD are a key driver of secondary care costs, interventions aimed at preventing and treating exacerbations effectively could significantly reduce the economic impact of this disease. In all of the participating counties, COPD was underdiagnosed and undertreated. Between 9% and 30% of patients were undiagnosed despite having symptoms consistent with COPD, and up to 65% of patients did not receive regular prescribed medication. Patients reported poor symptom control and considerable use of healthcare resources. Therefore, reducing the burden of COPD will involve better evaluation and diagnosis of patients with COPD, as well as improved management of chronic COPD symptoms by healthcare professionals. The survey also demonstrated that the societal costs of COPD were 4-17 times higher in patients with severe COPD than in patients with mild COPD. Patients with comorbid conditions (accounting for 30-57% of patients in each country) were also particularly costly to society. These results suggest that a high priority should be given to interventions aimed at delaying the progression of disease, preventing exacerbations and reducing the risk of comorbidities, in order to alleviate the clinical and economic burden of COPD in North America and Europe.
