Abstract
OBJECTIVES To find the economic burden of COPD and to identify the key cost drivers in the management of COPD patients across different European countries. BACKGROUND COPD is a major cause of mortality and morbidity and is associated with considerable economic burden on the individual and society. It limits the daily activities and working ability of the patients. METHODOLOGY We conducted a systematic search of PUBMED, SCIENCE DIRECT, Cochrane CENTRAL, SCOPUS, Google Scholar and SAGE Premier Databases to find scientific research articles evaluating the cost of COPD management from patient and societal perspective. RESULTS Estimated per patient per year direct cost in Norway, Denmark, Germany, Italy, Sweden, Greece, Belgium, and Serbia was €10,701, €9580, €7847, €7448, €7045, €2896, €1963, and €2047, respectively. Annual per patient cost of work productivity loss was highest in Germany as €5735 and lowest in Greece as €998. It was estimated as €4824, €2033 and €1298 in Bulgaria, Denmark and Sweden, respectively. Several factors found associated with increasing cost of COPD management that include but not limited to late diagnosis, severity of disease, frequency of exacerbation, hospital readmissions, non-adherence to the therapy and exposure to COPD risk factors. CONCLUSION Minimizing the COPD exacerbations and controlling the worsening of symptoms may potentially reduce the cost of COPD management at any stage.

Abstract
Background: Lack of information about economic burden of COPD is a major cause of lack of attention to this chronic condition from governments and policymakers. Objective: To find the economic burden of COPD in Asia, USA and Europe, and to identify the key cost driving factors in management of COPD patients. Methodology: Relevant studies assessing the cost of COPD from patient perspective or societal perspective were retrieved by thoroughly searching PUBMED, SCIENCE DIRECT, GOOGLE SCHOLAR, SCOPUS, and SAGE Premier Databases. Results: In the USA annual per patient direct medical cost and hospitalization cost were reported as $10,367 and $6852, respectively. In Asia annual per patient direct medical cost in Iran, Korea and Singapore was reported as $1544, $3077, and $2335, respectively. However, annual per patient hospitalization cost in Iran, Korea, Singapore, India, China, and Turkey was reported as $865, $1371, $1868, $296, $1477 and $1031, respectively. In Europe annual per patient direct medical cost was reported as $11,787, $10,552, $8644, $8203, $7760, $3190, $1889, $2162, and $2254 in Norway, Denmark, Germany, Italy, Sweden, Greece, Spain, Belgium, and Serbia, respectively. Conclusion: Limiting the disease to early stage and preventing exacerbations may reduce the cost of management of COPD.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease (COPD) affects over 12 million adults in the United States and is the third leading cause of 30-day readmissions. COPD is costly with almost $50 billion in direct costs annually. Total COPD costs can be up to double the identified direct costs because of comorbid disease and numerous indirect costs such as absenteeism. Acute exacerbations of COPD (AECOPD) are responsible for up to 70% of COPD-related healthcare costs; hospital readmissions alone account for over $15 billion annually. In this review, we aim to describe insights about the economic impact of COPD readmissions based on articles published over the last 18 months. RECENT FINDINGS Interventions aimed at reducing readmission, particularly those using interdisciplinary teams with bundled care interventions, were uniformly successful at improving the quality of care provided and demonstrating improved process measures. However, success at reducing readmissions and cost savings based on these interventions varied across the studies. SUMMARY The literature to date points to factors and conditions that may place patients at higher risk of readmissions and may lead to higher costs. Interventions aimed at reducing readmissions after index admissions for AECOPD have demonstrated variable results. Most interventions did not reflect cost-based analyses.

Abstract
BACKGROUND Evidence from several studies show poor guideline adherence to COPD treatment, but no such study has been undertaken in Norway. The objectives of this study, was to estimate and compare the guideline adherence to COPD treatment in general population-based and hospital-recruited COPD patients, and find possible predictors of guideline adherence. METHODS From the prospective, observational EconCOPD-study, we analysed guideline adherence for 90 population-based COPD cases compared to 245 hospital-recruited COPD patients. Overall guideline adherence was defined as correct pharmacological treatment, and influenza vaccination the preceding year, and having received smoking cessation advice. Multivariate logistic regression analysis was performed with the dichotomous outcome overall guideline adherence adjusting for relevant variables. RESULTS The overall guideline adherence for population-based COPD cases was 6.7%, significantly lower than the 29.8% overall guideline-adherence amongst hospital-recruited COPD patients. Adherence to pharmacological treatment guidelines was 10.0 and 35.5%, for the two recruitment sources, respectively. GOLD-stage 3 to 4 was associated with significantly better guideline adherence compared to GOLD-stage 2 (OR (95% CI) 18.9 (8.37,42.7)). The unadjusted difference between the two recruitment sources was completely explained by degree of airflow obstruction. CONCLUSION Overall guideline adherence was very low for both recruitment sources. We call for increased attention from authorities and healthcare personnel to improve the quality of care given to this patient group.

Abstract
Rationale: The efficacy of disease management programs in the treatment of patients with chronic obstructive pulmonary disease (COPD) remains uncertain.Objectives: To study the effect of disease management (DM) added to recommended care (RC) in ambulatory patients with COPD.Measurements and Main Results: In this trial, 1,202 patients with COPD (age, ≥40 yr), with moderate to very severe airflow limitation were randomly assigned either to DM plus RC (study intervention) or to RC alone (control intervention). RC included follow-up by pulmonologists, inhaled long-acting bronchodilators and corticosteroids, smoking cessation intervention, nutritional advice and psychosocial support when indicated, and supervised physical activity sessions. DM, delivered by trained nurses during patients' visits to the designated COPD centers and by remote contacts with the patients between these visits, included patient self-care education, monitoring patients' symptoms and adherence to treatment, provision of advice in case of acute disease exacerbation, and coordination of care vis-à-vis other healthcare providers. The primary composite endpoint was first hospital admission for respiratory symptoms or death from any cause. During 3,537 patient-years, 284 patients (47.2%) in the control group and 264 (44.0%) in the study intervention group had a primary endpoint event. The median (range) time elapsed until a primary endpoint event was 1.0 (0-4.0) years among patients assigned to the study intervention and 1.1 (0-4.1) years among patients assigned to the control intervention; adjusted hazard ratio, 0.92 (95% confidence interval, 0.77-1.08).Conclusions: DM added to RC was not superior to RC alone in delaying first hospital admission or death among ambulatory patients with COPD.

Abstract
OBJECTIVE To evaluate the efficacy of integrated Traditional Chinese Medicine-Western Medicine (TCM-WM) in the treatment of acute onset pulmonary heart disease (PHD). METHODS A total of 240 patients met the inclusion criteria and were enrolled. These inpatients were divided into group A (treatment group) and B (control group) in order of admission according to the principles of randomization and control. The research was performed simultaneously in three hospitals. Two groups were given basic treatment that included: controlled oxygen therapy, active and effective anti-infection, maintaining airway patency, correcting O2 deficiency and CO2 retention, correcting acid-base imbalance and electrolyte disturbance, reducing pulmonary hypertension and treating right heart failure, nutritional support and treatment of.complications. Group A was given basic treatment and integrated Traditional Chinese Medicine (TCM) differentiating therapy; group B was given basic therapy and a placebo that was similar in appearance and taste to TCM medicinal broth of pharmaceutical preparations, provided by Yibin Pharmaceutical Company (Yibin, China, Wuliangye Group). RESULTS The mortality in the treatment group decreased by 4.98% compared with the control group. The treatment group reported improved ventilation, corrected hypoxemia, improved nutritional status and promoted digestive functions. It also significantly improved the patient's self-life skills, improved the patient's quality of life and could shorten the length of hospital stay. CONCLUSION Comprehensive integrated TCM-WM treatment showed good clinical efficacy toward the acute onset period of PHD patients.

Abstract
Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66). Maintenance therapy (regular long-acting muscarinic antagonists, long-acting beta-2 agonists, inhaled corticosteroids, or theophylline) also increased the risk of AECOPD with both exacerbation definitions (incidence rate ratios 1.65 and 1.73, respectively). The risk of AECOPD was 59%–78% higher in the hospital sample than in the population sample. Conclusion If externally valid conclusions are to be made regarding incidence and predictors of AECOPD, studies should be based on general population samples or adjustments should be made on account of a likely higher incidence in other samples. Likewise, the effect of different AECOPD definitions should be taken into consideration.

Abstract
Objective To evaluate the impact of lung function, measured as forced expiratory volume in 1 second (FEV1) % predicted, on health care resource utilization and costs among patients with COPD in a real-world US managed-care population. Methods This observational retrospective cohort study utilized administrative claim data augmented with medical record data. The study population consisted of patients with one or more medical claims for pre- and postbronchodilator spirometry during the intake period (July 1, 2012 to June 30, 2013). The index date was the date of the earliest medical claim for pre- and postbronchodilator spirometry. Spirometry results were abstracted from patients’ medical records. Patients were divided into two groups (low FEV1% predicted [,50%] and high FEV1% predicted [≥50%]) based on the 2014 Global Initiative for Chronic Obstructive Lung Disease report. Health care resource utilization and costs were based on the prevalence and number of discrete encounters during the 12-month postindex follow-up period. Costs were adjusted to 2014 US dollars. Results A total of 754 patients were included (n=297 low FEV1% predicted group, n=457 high FEV1% predicted group). COPD exacerbations were more prevalent in the low FEV1% predicted group compared with the high group during the 12-month pre- (52.5% vs 39.6%) and postindex periods (49.8% vs 36.8%). Mean (standard deviation) follow-up all-cause and COPD-related costs were $27,380 ($38,199) and $15,873 ($29,609) for patients in the low FEV1% predicted group, and $22,075 ($28,108) and $10,174 ($18,521) for patients in the high group. In the multivariable analyses, patients in the low FEV1% predicted group were more likely to have COPD exacerbations and tended to have higher COPD-related costs when compared with patients in the high group. Conclusion Real-world data demonstrate that patients with COPD who have low FEV1% predicted levels use more COPD medications, have more COPD exacerbations, and incur higher COPD-related health care costs than those with high FEV1% predicted levels.

Abstract
BACKGROUND Co-morbidities are common in COPD; however, there is a lack of population-based studies evaluating the health economic impact of co-morbid diseases for subjects with COPD. The main objective of this study was to estimate annual direct health-care costs, divided into costs due to non-respiratory and respiratory conditions, comparing subjects with and without COPD. METHODS Subjects with and without COPD derived from population-based cohorts in northern Sweden have been invited to annual examinations involving spirometry and structured interviews since 2005. This paper is based on data from 1472 subjects examined in 2006. COPD classification was based on spirometry. RESULTS Mean annual costs for both respiratory and non-respiratory conditions were significantly higher for subjects with COPD than non-COPD subjects, in total USD 2139 vs. USD 1276 (p = 0.026), and COPD remained significantly associated with higher costs also after adjustment for common confounders as age, smoking habits, BMI and sex. The mean total cost increased with COPD disease severity and was higher for all severity stages (GOLD) than for non-COPD subjects. Hospitalization due to non-respiratory diseases was the main cost driver in COPD, after adjustment for common confounders amounting to about 46% (unadjusted 62%) of the total COPD-costs. CONCLUSIONS Costs were higher for COPD than non-COPD. In COPD, costs for co-morbid conditions were higher than those for respiratory conditions, and hospitalization due to co-morbid conditions was the main cost driver also when adjusted for common confounders.

Abstract
Despite the increasing availability of routine data, no analysis method has yet been presented for cost-of-illness (COI) studies based on massive data. We aim, first, to present such a method and, second, to assess the relevance of the associated gain in numerical efficiency. We propose a prevalence-based, top-down regression approach consisting of five steps: aggregating the data; fitting a generalized additive model (GAM); predicting costs via the fitted GAM; comparing predicted costs between prevalent and non-prevalent subjects; and quantifying the stochastic uncertainty via error propagation. To demonstrate the method, it was applied to aggregated data in the context of chronic lung disease to German sickness funds data (from 1999), covering over 7.3 million insured. To assess the gain in numerical efficiency, the computational time of the innovative approach has been compared with corresponding GAMs applied to simulated individual-level data. Furthermore, the probability of model failure was modeled via logistic regression. Applying the innovative method was reasonably fast (19 min). In contrast, regarding patient-level data, computational time increased disproportionately by sample size. Furthermore, using patient-level data was accompanied by a substantial risk of model failure (about 80 % for 6 million subjects). The gain in computational efficiency of the innovative COI method seems to be of practical relevance. Furthermore, it may yield more precise cost estimates.

Abstract
Objectives We aimed to estimate incremental productivity losses (sick leave and disability) of spirometry-defined chronic obstructive pulmonary disease (COPD) in a population-based sample and in hospital-recruited patients with COPD. Furthermore, we examined predictors of productivity losses by multivariate analyses. Methods We performed four quarterly telephone interviews of 53 and 107 population-based patients with COPD and controls, as well as 102 hospital-recruited patients with COPD below retirement age. Information was gathered regarding annual productivity loss, exacerbations of respiratory symptoms and comorbidities. Incremental productivity losses were estimated by multivariate quantile median regression according to the human capital approach, adjusting for sex, age, smoking habits, education and lung function. Main effect variables were COPD/control status, number of comorbidities and exacerbations of respiratory symptoms. Results Altogether 55%, 87% and 31% of population-based COPD cases, controls and hospital patients, respectively, had a paid job at baseline. The annual incremental productivity losses were 5.8 (95% CI 1.4 to 10.1) and 330.6 (95% CI 327.8 to 333.3) days, comparing population-recruited and hospital-recruited patients with COPD to controls, respectively. There were significantly higher productivity losses associated with female sex and less education. Additional adjustments for comorbidities, exacerbations and FEV1% predicted explained all productivity losses in the population-based sample, as well as nearly 40% of the productivity losses in hospital-recruited patients. Conclusions Annual incremental productivity losses were more than 50 times higher in hospital-recruited patients with COPD than that of population-recruited patients with COPD. To ensure a precise estimation of societal burden, studies on patients with COPD should be population-based.

THE CLINICAL RESPIRATORY JOURNAL 2013; 7:375-81. [PMID: 23347439 DOI: 10.1111/crj.12018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2012] [Revised: 12/03/2012] [Accepted: 12/16/2012] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common cause of hospitalisation, and the readmission rate is high. We aimed to determine whether patients discharged from a pulmonary department (PD) after an AECOPD episode had a lower COPD-related readmission rate during the next 12 months than comparable patients discharged from other internal medicine departments (ODs). METHODS The medical records of 566 patients discharged after an episode of AECOPD between March 2006 and December 2008 at Oslo University Hospital, Aker, were reviewed retrospectively. Demographic and medical data, together with number of readmissions because of AECOPD during 12 months following the index admission were extracted. We matched patients discharged from the PD and the ODs using a propensity score and used the paired t-test to compare COPD-related readmission rates between the matched patients. RESULTS In total, 481 patients were included in the analysis, 247 patients discharged from the PD and 234 from ODs. The propensity score matching process resulted in 155 well-matched pairs. The mean (standard deviation) number of readmissions within 1 year was 0.8 (1.3) for the PD versus 1.1 (1.9) for ODs (P = 0.09). After adjusting for exposure time, the corresponding readmission rates were 1.1 (2.3) and 1.6 (4.0) per year, respectively (P = 0.17). CONCLUSION There was little difference in COPD-related readmission rates between comparable patients discharged from the PD and the ODs after an AECOPD during 1 year following the index admission.

Respir Med 2013; 107:1931-8. [PMID: 23910072 DOI: 10.1016/j.rmed.2013.07.012] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2013] [Revised: 06/24/2013] [Accepted: 07/11/2013] [Indexed: 11/30/2022]
Abstract
OBJECTIVES The objectives of the presented study were to estimate societal costs of COPD in Sweden, the relationship between costs and disease severity, and possible changes in the costs during the last decade. METHODS Subjects with COPD derived from the general population in Northern Sweden were interviewed by telephone regarding their resource utilisation and productivity losses four times quarterly during 2009-10. Mean annual costs were estimated for each severity stage of COPD. RESULTS A strong relationship was found between disease severity and costs. Estimated mean annual costs per subject of mild, moderate, severe and very severe COPD amounted to 596 (SEK 5686), 3245 (SEK 30,957), 5686 (SEK 54,242), and 17,355 euros (SEK 165,569), respectively. The main cost drivers for direct costs were hospitalisations (for very severe COPD) and drugs (all other severity stages). The main cost driver for indirect costs was productivity loss due to sick-leave (for mild COPD) and early retirement (all other severity stages). Costs appeared to be lower in 2010 than in 1999 for subjects with severe and very severe COPD, but higher for those with mild and moderate COPD. CONCLUSION Our results show that costs of COPD are strongly related to disease severity, and scaling the data to the whole Swedish population indicates that the total costs in Sweden amounted to 1.5 billion euros (SEK 13.9 bn) in 2010. In addition, costs have decreased since 1999 for subjects with severe and very severe COPD, but increased for those with mild and moderate COPD.

Abstract
OBJECTIVE Assess the cost effectiveness of budesonide/formoterol (BUD/FORM) Turbuhaler(®)+tiotropium (TIO) HandiHaler(®) vs. placebo (PBO)+TIO in patients with chronic obstructive pulmonary disease (COPD) eligible for inhaled corticosteroids/long-acting β2-agonists (ICS/LABA). METHODS The cost-effectiveness analysis was based on the 12-week, randomised, double-blind CLIMB trial. The study included 659 patients with pre-bronchodilator forced expiratory volume in 1 s ≤ 50% and ≥1 exacerbation requiring systemic glucocorticosteroids or antibiotics the preceding year. Patients received BUD/FORM 320/9 μg bid + TIO 18 μg qd or PBO bid + TIO 18 μg qd. Effectiveness was defined as the number of severe exacerbations (hospitalisation/emergency room visit/systemic glucocorticosteroids) avoided. A sub-analysis included antibiotics in the definition of an exacerbation. Resource use from CLIMB was combined with Danish (DKK), Finnish (€), Norwegian (NOK) and Swedish (SEK) unit costs (2010). The incremental cost-effectiveness ratios (ICERs) for BUD/FORM + TIO vs. PBO + TIO were estimated using descriptive statistics and uncertainty around estimates using bootstrapping. Analyses were conducted from the societal and healthcare perspectives in Denmark, Finland, Norway and Sweden. RESULTS From a societal perspective, the ICER was estimated at €174/severe exacerbation avoided in Finland while BUD/FORM + TIO was dominant in the other countries. From the healthcare perspective, ICERs were DKK 1580 (€212), €307 and SEK 1573 (€165) per severe exacerbation avoided for Denmark, Finland and Sweden, respectively, while BUD/FORM + TIO was dominant in Norway. Including antibiotics decreased ICERs by 8-15%. Sensitivity analyses showed that results were overall robust. CONCLUSION BUD/FORM + TIO represents a clinical and economic benefit to health systems and society for the treatment of COPD in the Nordic countries. (ClinicalTrials.gov Identifier: NCT00496470).

Abstract
Comorbidities, are common in COPD, have been associated with poor outcomes and are thought to relate to systemic inflammation. To investigate comorbidities in relation to systemic inflammation and outcomes we recorded comorbidities in a well characterized cohort (ECLIPSE study) for 2164 clinically stable COPD subjects, 337 smokers and 245 non-smokers with normal lung function. COPD patients had a higher prevalence of osteoporosis, anxiety/panic attacks, heart trouble, heart attack, and heart failure, than smokers or nonsmokers. Heart failure (Hazard Ratio [HR] 1.9, 95% Confidence Interval [CI] 1.3-2.9), ischemic heart disease (HR 1.5, 95% CI 1.1-2.0), heart disease (HR 1.5, 95% CI 1.2-2.0), and diabetes (HR 1.7, 95% CI 1.2-2.4) had increased odds of mortality when coexistent with COPD. Multiple comorbidities had accumulative effect on mortality. COPD and cardiovascular disease was associated with poorer quality of life, higher MRC dyspnea scores, reduced 6MWD, higher BODE index scores. Osteoporosis, hypertension and diabetes were associated with higher MRC dyspnea scores and reduced 6MWD. Higher blood concentrations of fibrinogen, IL-6 and IL-8 levels occurred in those with heart disease. Comorbidity is associated with poor clinical outcomes in COPD. The comorbidities of heart disease, hypertension and diabetes are associated with increased systemic inflammation.

Abstract
The aim of this study was to describe the impact of chronic obstructive pulmonary disease (COPD) on health status in the Burden of Obstructive Lung Disease (BOLD) populations. We conducted a cross-sectional, general population-based survey in 11 985 subjects from 17 countries. We measured spirometric lung function and assessed health status using the Short Form 12 questionnaire. The physical and mental health component scores were calculated. Subjects with COPD (post-bronchodilator forced expiratory volume in 1 s/forced vital capacity <0.70, n = 2269) had lower physical component scores (44±10 versus 48±10 units, p<0.0001) and mental health component scores (51±10 versus 52±10 units, p = 0.005) than subjects without COPD. The effect of reported heart disease, hypertension and diabetes on physical health component scores (-3 to -4 units) was considerably less than the effect of COPD Global Initiative for Chronic Obstructive Lung Disease grade 3 (-8 units) or 4 (-11 units). Dyspnoea was the most important determinant of a low physical and mental health component scores. In addition, lower forced expiratory volume in 1 s, chronic cough, chronic phlegm and the presence of comorbidities were all associated with a lower physical health component score. COPD is associated with poorer health status but the effect is stronger on the physical than the mental aspects of health status. Severe COPD has a greater negative impact on health status than self-reported cardiovascular disease and diabetes. COPD is related to worse health status: impairment is greater than in self-reported cardiovascular diseases or diabeteshttp://ow.ly/p1cIx

Abstract
AIM While it is known that severe COPD has substantial economic consequences, evidence on resource use and costs in mild disease is scarce. The objective of this study was to investigate excess costs of early stages of COPD. METHODS Using data from two population-based studies in Southern Germany, current GOLD criteria were applied to pre-bronchodilator spirometry for COPD diagnosis and staging in 2255 participants aged 41 to 89. Utilization of physician visits, hospital stays and medication was compared between participants with COPD stage I, stage II+ (II or higher) and controls. Costs per year were calculated by applying national unit costs. In controlling for confounders, two-part generalized regression analyses were used to account for the skewed distribution of costs and the high proportion of subjects without costs. RESULTS Utilization in all categories was significantly higher in COPD patients than in controls. After adjusting for confounders, these differences remained present in physician visits and medication, but not in hospital days. Adjusted annual costs did not differ between stage I (€ 1830) and controls (€ 1822), but increased by about 54% to € 2812 in stage II+. CONCLUSION The finding that utilization and costs are considerably higher in moderate but not in mild COPD highlights the economic importance of prevention and of interventions aiming at early diagnosis and delayed disease progression.
